背景技术
新无线(new radio，NR)系统是目前主流的无线通信技术，其针对车联网(vehicle to everthing，V2X)业务特性及新的业务传输需求，目标是支持更低延迟，更高可靠性的V2X通信。但是，在侧链路(sidelink)中，接收终端设备(RX UE)会一直监听侧链路控制信息(sidelink control information，SCI)，查看是否有来自于发送终端设备(TX UE)的信息。
然而，UE自主选择资源的场景下，RX UE并不是一直在和TX UE进行有效信息的交互。那么，在收发UE之间没有数据交互的时候，如果RX UE还持续监听SCI，会增加RX UE的功耗。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。以下描述中，参考形成本申请一部分并以说明之方式示出本申请实施例的具体方面或可使用本申请实施例的具体方面的附图。应理解，本申请实施例可在其它方面中使用，并可包括附图中未描绘的结构或逻辑变化。例如，应理解，结合所描述方法的揭示内容可以同样适用于用于执行所述方法的对应设备或系统，且反之亦然。例如，如果描述一个或多个具体方法步骤，则对应的设备可以包含如功能单元等一个或多个单元，来执行所描述的一个或多个方法步骤(例如，一个单元执行一个或多个步骤，或多个单元，其中每一个都执行多个步骤中的一个或多个)，即使附图中未明确描述或说明这种一个或多个单元。另一方面，例如，如果基于如功能单元等一个或多个单元描述具体装置，则对应的方法可以包含一个步骤来执行一个或多个单元的功能性(例如，一个步骤执行一个或多个单元的功能性，或多个步骤，其中每一个执行多个单元中一个或多个单元的功能性)，即使附图中未明确描述或说明这种一个或多个步骤。进一步，应理解的是，除非另外明确提出，本文中所描述的各示例性实施例和/或方面的特征可以相互组合。
新无线(new radio，NR)系统是目前主流的无线通信技术，其针对车联网(vehicle to everthing，V2X)业务特性及新的业务传输需求，目标是支持更低延迟，更高可靠性的V2X通信。但是，在侧链路(sidelink，SL)中，接收端用户设备(RX UE)会一直监听SCI，查看是否有来自及发送端用户设备的(TX UE)的信息。然而，在sidelink中，RX UE和TX UE之间不是一直有业务传输。那么，在收发UE之间没有数据交互的时候，如 果RX UE还持续监听SCI，会增加RX UE的功耗。
那么，为了解决侧链路中UE持续监听SCI所造成的功耗较高的问题，本申请实施例提供一种通信方法，该通信方法可以应用于通信系统，该通信系统可以为侧链路通信系统，侧链路通信系统可以适应于车联网(vehicle to everything，V2X)、智能网联汽车及自动驾驶汽车等领域。上述通信系统中可以包括至少一个通信设备。在一种场景下，图1为本申请实施例中的通信系统的一种架构示意图，参见图1所示，该通信系统10中可以包括：网络设备11和终端设备12。在另一种场景下，图2为本申请实施例中的通信系统的另一种架构示意图，参见图2所示，该通信系统10还可以包括多个终端设备12。当然，在本申请实施例中，通信系统包含的网元的类型、数量，以及网元之间的连接关系不限于此。
在本申请实施例中，终端设备与网络设备通信的同时，还可以与其他终端设备通信。网络设备可以对终端设备之间通信的侧链路(sidelink)进行资源的配置、调度、协调等，以辅助终端设备之间直接进行通信。终端设备也可以自行对于其他终端设备之间通信的侧链路进行资源的配置、调度、协调等，本申请实施例不做具体限定。
在一些可能的实施方式中，上述网络设备可以是接入网侧用于支持终端接入无线通信系统的设备，例如，可以是5G接入技术通信系统中的下一代基站(next generation NodeB，gNB)、发送接收点(transmission reception point，TRP)、中继节点(relay node)、接入点(access point，AP)、路边装置(road site unit，RSU)等。
上述终端设备可以是一种向用户提供语音或者数据连通性的设备，例如也可以称为用户设备(user equipment，UE)、移动台(mobile station)、用户单元(subscriber unit)、站台(STAtion)或者终端设备(terminal equipment，TE)等。通信设备可以为蜂窝电话(cellular phone)、个人数字助理(personal digital assistant，PDA)、无线调制解调器(modem)、手持V2P设备(handheld vehicle to perdestrian)、膝上型电脑(laptop computer)、无绳电话(cordless phone)、无线本地环路(wireless local loop，WLL)台或者平板电脑(pad)、中继节点、AP等。随着无线通信技术的发展，可以接入无线通信系统、可以与无线通信系统的网络侧进行通信，或者通过无线通信系统与其它设备进行通信的设备都可以是本申请实施例中的终端设备，譬如，智能交通中的终端、汽车或RSU、智能家居中的家用设备、智能电网中的电力抄表仪器、电压监测仪器、环境监测仪器、智能安全网络中的视频监控仪器、收款机等。通信设备可以是静态固定的，也可以是移动的。
进一步地，在侧链路传输场景中，上述通信设备(可以包括终端设备和/或网络设备)按照数据传输方向可以分为发送端设备和接收端设备。其中，发送端设备可以包括发送端网络设备、发送终端设备、发送端用户设备等；接收端设备可以包括接收端网络设备、接收终端设备、接收端用户设备等。
需要说明的是，上述发送端设备(或者发送端网络设备、发送终端设备、发送端用户设备等)以及接收端设备(或者接收端网络设备、接收终端设备、接收端用户设备等)是针对某一条侧链路连接(sidelink connection)而言的。例如，一个通信设备(或者网络设备、终端设备、用户设备等)对于侧链路连接A来说，可以为发送端设备(或者发送端网络设备、发送终端设备、发送端用户设备等)；而对于侧链路连接B来说，该通 信设备(或者网络设备、终端设备、用户设备等)可以为接收端设备(或者接收端网络设备、接收终端设备、接收端用户设备等)。
下面结合上述通信系统，对本申请实施例提供的通信方法进行说明。
在NR SL中，网络设备，如基站为UE的SL通信配置资源池，一个资源池为一些时频资源的集合。UE在SL链路上进行通信的资源是从预配置或者基站侧配置的资源池中确定的。具体的，TX UE从网络设备获取在SL链路进行通信的传输资源有两种模式，分别是mode1和mode2。其中，上述预配置的资源可以是从核心网的网元获取的，也可以是预置在UE内的。
在mode1下，基站通过调度为TX UE分配SL传输资源。在此模式下，当TX UE有SL待传输数据时，通过Uu口向基站上报SL缓存状态报告(buffer status report，BSR)MAC CE，以告知基站当前TX UE在PC5口的待传输数据的数据量。基站可以为TX UE动态分配传输资源。
在mode2下，UE根据需要自主从预配置或者基站配置的资源池中选择传输资源，不需要基站进行调度。UE确定的SL资源是基站配置的(如通过RRC信令配置或者系统信息块(system information block，SIB)配置)，或者预配置的。这里所说的预配置可以是从核心网的网元获取，也可以是预置在UE内的。
在UE自主选择资源(即mode2)场景下，TX UE进行一次资源选择，会为一个业务，如一个通信目标(用destination ID来指示，如destination L1 ID或destination L2 ID)、一个侧链路连接(如无线资源控制(radio resource control，RRC)连接)、一个SL链路、一个源和目标对(如{source L2/L1 ID，destination L2/L1 ID})、一个侧链路业务、一个逻辑信道、一个资源池、一个传输块(transform block，TB)、一个或者多个媒介访问控制层分组数据单元(medium access control packet data unit，MAC PDU)等选择至少一个资源(通常可以包括用于一次传输机会的1个到3个资源及其对应的周期性资源)，至少一个资源用于新传或者重传该业务，这至少一个资源也可以称为预留资源(reserved resources)。
图3为本申请实施例中的在UE自主选择资源场景下的通信方法的流程示意图，参见图3所示，该方法可以包括：
S301：TX UE进行感知(sensing)；
TX UE持续监听其他UE发送的SCI，并按照SCI的指示进行测量，获得测量结果。这里，TX UE监听到其他UE的SCI后，对SCI进行解调，解调的SCI至少可以反映出sidelink上资源的使用情况。
在本申请实施例中，上述“测量”可以包括基于sidelink解调参考信号(demodulation reference signal，DMRS)的sidelink RSRP的测量，例如，测量PSCCH的参考信号接收功率(reference signal receiving power，RSRP)(即PSCCH-RSRP)或者PSSCH-RSRP；或者，还可以测量侧链路接收信号强度指示符(sidelink received signal strength indicator，S-RSSI)等。其中PSCCH-RSRP是对PSCCH关联的DMRS测量确定的，PSSCH-RSRP是对PSSCH关联的DMRS测量确定的。当然，UE还可以对SCI指示的资源的其他参数进行测量，对此本申请实施例不做具体限定。
S302：TX UE根据得到的测量结果，对SCI所指示的资源进行资源排除，确定候选 资源集。
TX UE从SCI指示的资源中，将测量结果满足于某一个条件的资源排除，由此便可以得到TX UE的候选资源集，那么，TX UE在传输业务时可以在候选资源集中选择资源进行传输。例如，通过S301，TX UE对SCI进行参考信号接收功率的测量，获得PSCCH-RSRP或者PSSCH-RSRP，然后，TX UE可以将PSCCH-RSRP或者PSSCH-RSRP满足预设条件的资源排除，或者，TX UE可以根据SCI的指示，将其他UE占用的资源排除，再者，TX UE还可以其他UE占用的资源、且RSRP高于预设门限值的资源排除。
在实际应用中，上述预设条件可以为RSRP值在预设范围内，例如RSRP值在所有测量得到的RSRP值由大到小或者由小到大排序后前20％，或者，RSRP值高于所有RSRP值的70％，当然，上述预设条件还可以为其他条件，如可以根据TX UE的传输优先级与其他UE的SCI中指示的传输优先级来设定，本申请实施例不做具体限定。
在一些可能的实施方式中，TX UE还可以通过S301解调SCI，获得资源的子载波间隔配置，RX UE还可以根据资源的子载波间隔配置，对资源进行筛选，使得选择的子载波间隔能够满足传输需求的资源，以供后续侧链路传输使用。
当然，TX UE可以根据其他条件进行资源排除，本申请不做具体限定。
S303：TX UE从候选资源集中选取用于侧链路传输的资源；
其中，TX UE所选取的资源可以理解为预留资源。
在业务到来之后，TX UE首先进行资源选择或资源重选的校验，来确定是否触发资源选择或重选；如果触发资源选择或重选，则TX UE确定资源预留周期、选定混合自动重传请求(hybrid automatic repeat request，HARQ)重传次数等；然后，TX UE从候选资源集中，根据选定的频域资源数及载波上允许的逻辑信道的可用侧链路数据的剩余包延迟预算(packet delay budge，PDB)选定用于一次传输机会的时频资源，进一步TX UE还可以利用选定的时域资源，以确定好的资源预留周期再选定对应的周期性资源集。若TX UE确定没有重传，则可以将TX UE选定的时域资源及其对应的周期性资源集视为“选定的SL grant(授权)”
可选的，TX UE根据HARQ重传次数，确定有一次或多次重传，且物理层指示的资源中还有可用的资源来用于多次传输机会，则根据选定的频域资源数、选定的HARQ重传次数及载波上允许的逻辑信道的可用SL数据的剩余PDB，从可用资源中为一次或多次传输机会选定时频资源。然后利用该时频资源及资源预留周期选定对应的周期资源集，并将选定的资源及其对应的这周期性资源集视为“选择的SL grant”(资源)
在本申请实施例中，上述S303中的业务可以包括：通信目标、侧链路连接(如源和目标对、sidelink链路等)、逻辑信道、资源池(resource pool)、侧链路业务、MAC PDU、TB等其中的一个或者多个的组合，本申请实施例对此不做具体限定。当业务为MAC PDU时，MAC PDU可以为一个或者多个。需要注意到的是，上述通信目标可以通过destination ID(通信目标标识)来标识，本申请不做具体限定。
S304：TX UE对预留资源进行重新评估；
在进行业务传输之前，TX UE还会对预留资源进行重新评估，看通过S303选择的预留资源是否能够用于侧链路传输，以保证最终选择的资源是可以用于侧链路传输的。
S305：若评估结果表示预留资源无法用于侧链路传输，则TX UE触发资源重选，返回S302；
S306：若评估结果表示预留资源可以用于侧链路传输，则TX UE采用预留资源开始侧链路传输；
S307：在使用预留资源传输的过程中，TX UE判断是否触发资源重选；
在S305和S307中，因为一些原因可能会导致预留资源无法用于侧链路传输，因此，TX UE还需要对第一资源进行评估，判断是否触发资源重选。例如，上述原因可以包括：上层配置或重配资源池；或，无configured sidelink gran；或，在过去一秒MAC实体在任何configured sidelink grant指示的资源上即无新传又无重传；或，配置了sl-ReselectAfter、且configured sidelink grant指示的连续未使用的传输机会达到sl-ReselectAfter；或，configured sidelink grant指示的传输资源不能满足根据对应的逻辑信道的优先级确定的某个逻辑信道上数据的时延要求，且MAC实体选择不进行相应单个MAC PDU的传输；或，UE收到的SCI指示的逻辑信道的优先级比待传数据的逻辑信道的优先级更高，该SCI调度的某个sl传输预期会与当前预留的某个资源重叠，且该SCI指示的sl传输的SL-RSRP测量结果高于门限。当第一资源满足如上述任意条件时，清除该SL process关联的预留资源(若有的话)，并触发TX资源选择/重选。
S308：若触发资源重选，则TX UE返回S302；
S309：若不触发资源重选，则TX UE继续使用预留资源进行侧链路传输。
通过上述过程，TX UE自主选择用于侧链路传输资源。为了节约RX UE的功耗，可以为RX UE配置DRX功能，一个DRX周期(DRX cycle)可以分为激活期(onduration)和睡眠期(opportunity for DRX)，“on duration”的这段时间是UE监控下行PSCCH和/或PSSCH子帧的时间，在这段时间里，UE是处于唤醒状态的，可以接收来自TX UE的传输；“opportunity for DRX”的这段时间是DRX睡眠时间，即UE为了省电，进入了睡眠状态，关闭自身的接收机，而不监控PSCCH和/或PSSCH子帧的时间。这样就可能导致如果RX UE在激活期没有监听到SCI，就会进入睡眠期，从而导致RX UE无法在TX UE所选择的资源上接收侧链路传输。
在实际应用中，DRX配置中的激活期可以为周期性的。
那么，为了解决这个问题，本申请实施例提供一种通信方法，可以应用于上述通信系统中的第一通信设备，如TX UE。
首先，需要说明的是，本申请实施例中所说的“资源与DRX激活期在时域上存在交集”可以理解为：资源在时域上全部或者部分位于DRX激活期的时间范围内。反之，“资源与DRX激活期在时域上不存在交集”可以理解为：资源在时域上位于DRX激活期的时间范围外，资源与DRX激活期在时域上是分开的。例如，图4为本申请实施例中的资源与DRX激活期的第一种示意图，参见图4所示，在时域上，资源位于DRX激活期的时间范围内，也就是说该资源包含于DRX激活期；或者，图5为本申请实施例中的资源与DRX激活期的第二种示意图，参见图5所示，在时域上，资源中的一部分，如至少一个符号位于DRX激活期内；图6为本申请实施例中的资源与DRX激活期的第三种示意图，参见图6所示，在时域上，资源没有一个符号位于DRX激活期内。在本申请其他实施例中，资源与DRX激活期在时域上的关系可以参见图4至图6的描述，下面不再 赘述。
在本申请实施例中，“当…时”仅用于表示步骤的执行条件，对步骤的执行时机不做限定，也可以理解为“如果”或者“若”。
在一些可能的实施方式中，DRX配置可以是按照每(per)业务进行配置的，DRX配置信息中可以包括DRX激活期。这里，“业务”可以如上所述，可以包括：通信目标、侧链路连接、源和目标对、sidelink链路、逻辑信道、资源池、侧链路业务、MAC PDU、TB等其中的一个或者多个的组合，本申请实施例对此不做具体限定。
假设，以第一业务为destination ID标识的通信目标为例，可以为每一个destination ID配置DRX配置信息。可以理解的，DRX配置可以是由基站为UE配置的，也可以是TX UE或者RX UE自行确定的，还可以是收发UE之间协商配置的，还可以是预先设置于UE中的，本申请实施例不做具体限定。
图7为本申请实施例中的第一通信设备侧通信方法的第一流程示意图，参见图7所示，该方法。包括：
S701：第一通信设备进行感知(sensing)；
第一通信设备持续监听其他UE发送的SCI，并按照SCI的指示进行测量，获得测量结果。这里，第一通信设备监听到其他UE的SCI后，对SCI进行解调，解调的SCI至少可以反映出sidelink上资源的使用情况。
在本申请实施例中，上述“测量”可以包括基于sidelink DMRS的L1sidelink RSRP的测量，例如，测量PSCCH的RSRP(即PSCCH-RSRP)或者PSSCH-RSRP；或者，还可以测量S-RSSI等。其中PSCCH-RSRP是对PSCCH关联的DMRS测量获得的，PSSCH-RSRP是对PSSCH关联的DMRS测量获得的。当然，第一通信设备还可以对SCI的其他参数进行测量，对此本申请实施例不做具体限定。
S702：第一通信设备根据得到的测量结果，对SCI所指示的资源进行资源排除。
第一通信设备从SCI指示的资源中，将测量结果满足于某一个条件的资源排除，由此便可以得到第一通信设备的候选资源集，那么，第一通信设备在传输业务时可以在候选资源集中选择资源进行传输。例如，通过S701，第一通信设备对SCI进行参考信号接收功率的测量，获得PSCCH-RSRP或者PSSCH-RSRP，然后，第一通信设备可以将PSCCH-RSRP或者PSSCH-RSRP满足预设条件的资源排除，或者，第一通信设备可以根据SCI的指示，将其他UE占用的资源排除，再者，第一通信设备还可以其他UE占用的资源、且相应RSRP高于预设门限值的资源排除。
在实际应用中，上述预设条件可以为RSRP值在预设范围内，例如RSRP值在所有测量得到的RSRP值由大到小或者由小到大排序后前20％，或者，RSRP值高于所有RSRP值的70％，当然，上述预设条件还可以为其他条件，如可以根据第一通信设备的传输优先级与其他UE的SCI中指示的传输的优先级来设定，本申请实施例不做具体限定。
在一些可能的实施方式中，第一通信设备还可以通过S701解调SCI，获得资源的子载波间隔配置，第一通信设备还可以根据资源的子载波间隔配置，对资源进行筛选，使得选择的子载波间隔满足传输需求的资源，以供后续侧链路传输使用。
当然，第一通信设备可以根据其他条件进行资源排除，本申请不做具体限定。
S703：第一通信设备确定用于侧链路传输的第一候选资源和第一业务；
第一通信设备通过S702确定第一候选资源，并获取自身当前可确定的第一业务，第一业务可以包括当前业务和/或历史业务。这里，“第一业务”可以如上所述，假设，以第一业务为destination ID标识的通信目标为例，第一通信设备可以确定至少一个destination ID作为候选destination ID集合，候选destination ID集合可以包括第一通信设备当前可选的destination ID，和/或历史可选的destination ID。
S704：第一通信设备从第一候选资源中确定第一资源；
由于DRX配置是针对第一业务进行配置的，那么，第一通信设备可以从第一候选资源中，选择与第一激活期存在交集的资源作为第二候选资源，进而从第二选择资源中确定第一资源。此时，第一资源可以理解为预留资源。
在本申请实施例中，第一通信设备可以通过如S303所述的方法，从第二候选资源中确定第一资源。
在本申请实施例中，为了实现资源与第一业务的DRX激活期匹配，上述第一激活期可以包括第一业务对应的至少一个DRX激活期，例如，第一激活期可以为一个destination ID对应的DRX激活期或者多个destination ID对应的DRX激活期。
可以理解的，如果存在多个destination ID，第一激活期可以为多个destination ID对应的DRX配置中的多个DRX激活期的并集；那么，第一通信设备可以从第一候选资源中选择与该并集存在交集的资源作为第二候选资源，然后，第一通信设备还可以从第二候选资源中选择第一资源，例如，第一通信设备从第一候选资源中选择部分或者全部位于上述等多个DRX激活期所组成的并集中得到资源作为第二候选资源，再从第二候选资源中，根据选定的频域资源数及载波上允许的逻辑信道的可用侧链路数据的剩余PDB选定用于一次传输机会的时频资源，进一步还可以利用选定的时域资源，以确定好的资源预留周期再选定对应的周期性资源。
或者，如果存在一个destination ID，第一激活期可以为该destination ID对应的DRX配置中的多个DRX激活期，那么，第一通信设备可以选择在时域上与第一业务对应的DRX激活期的交集满足第一条件的资源作为第二候选资源。
在实际应用中，上述第一条件可以包括：在时域上与第一业务对应的DRX激活期的交集最大、在时域上与第一业务对应的DRX激活期的交集在预设范围(可以为经验值)内、在时域上与第一业务对应的DRX激活期的交集大于预设门限等。例如，一个destination ID对应的DRX激活期为子帧0，那么，第一通信设备将第一候选资源中与子帧0的交集的符号数最大的资源确定为第二候选资源，或者，第一通信设备将第一候选资源中与子帧0的交集的符号数大于80％(也就是11个符号)的资源确定为第二候选资源，再或者，第一通信设备将第一候选资源中在子帧0的符号1至符号12内的资源确定为第二候选资源。类似的，一个destination ID对应的DRX激活期为子帧0、子帧3、子帧6，那么，第一通信设备将第一候选资源中分别与子帧0、子帧3、子帧6存在交集最大的多个资源确定为第二候选资源，即选择第一候选资源中与子帧0的交集最大的资源a，与子帧3交集最大的资源b，与子帧6交集最大的资源c，将资源a、b、c确定为第二候选资源；或者，第一通信设备将第一候选资源中分别与子帧0、子帧3、子帧6的交集的符号数大于80％的多个资源确定为第二候选资源，再或者，第一通信设备将第一候选资源中分别位于子帧0、子帧3、子帧6的符号1至符号12内的多个资源确定为第二候 选资源。当然，第一条件还可以为其他条件，本申请实施例不做具体限定。
至此，第一通信设备完成资源选择。
S705：第一通信设备对第一资源进行重新评估；
在进行业务传输之前，第一通信设备还会对第一资源进行重新评估，看通过S703选择的第一资源是否能够用于侧链路传输。例如，由于存在新业务到达、第一资源被其他UE占用等情况的发生，就可能导致之前选择的第一资源无法用于侧链路传输，所以，第一通信设备需要重新对选择的第一资源进行评估。
S706：若评估结果表示第一资源无法用于侧链路传输，则第一通信设备触发资源重选，返回S702；
S707：若评估结果表示第一资源可以用于侧链路传输，则第一通信设备在采用第一资源开始侧链路传输；
S708：在使用第一资源传输的过程中，第一通信设备判断是否触发资源重选；
第一通信设备在侧链路传输过程中，因为一些原因，可能会导致第一资源无法用于侧链路传输，因此，第一通信设备还需要对第一资源进行评估，判断是否触发资源重选。例如，上述原因可以包括：上层配置或重配资源池；或，无configured sidelink gran；或，在过去一秒MAC实体在任何configured sidelink grant指示的资源上即无新传又无重传；或，配置了sl-ReselectAfter、且configured sidelink grant指示的连续未使用的传输机会达到sl-ReselectAfter；或，configured sidelink grant指示的传输资源不能满足根据对应的逻辑信道的优先级确定的某个逻辑信道上数据的时延要求，且MAC实体选择不进行相应单个MAC PDU的传输；或，UE收到的SCI指示的逻辑信道的优先级比待传数据的逻辑信道的优先级更高，该SCI调度的某个sl传输预期会与当前预留的某个资源重叠，且该SCI指示的sl传输的SL-RSRP测量结果高于门限。当第一资源满足如上述任意条件时，清除该SL process关联的预留资源(若有的话)，并触发TX资源选择/重选。
S709：若触发资源重选，则第一通信设备返回S702；
S710：若不触发资源重选，则第一通信设备继续使用第一资源进行侧链路传输。
在一些可能的实施方式中，第一通信设备执行S703至S704选择的第一资源还可以作为候选资源，以供第一通信设备从候选资源中选取预留资源，进而执行S705至S710。
在本申请实施例中，通过上述S701至S710所述的方法，第一通信设备选择与第一业务对应的DRX激活期存在交集的资源作为预留资源，并使用该预留资源进行侧链路传输，如此能够保证第一通信设备可以在激活期内接收到来自第二通信设备(如TX UE)的传输，节约RX UE的功耗，并保证第一通信设备与第二通信设备之间的侧链路传输。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，如果在存在多个destination ID的场景下，第一通信设备在执行S707使用第一资源开始侧链路传输之前，还可以对第一业务，也就是destination ID进行选择，此时，第一通信设备可以从上述多个destination ID中选择对应的DRX激活期与第一资源在时域上存在交集的destination ID(用于标识第二业务)，也就是说，最后选择的destination ID对应的DRX激活期与预留资源在时域上存在交集。
在一些可能的实施方式中，第一通信设备还可以在执行S706之前，采用上述方法进行destination ID进行选择，使得选中的destination ID在时域上与预留资源存在交集。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，第一通信设备在执行S701时，首先，第一通信设备的MAC层可以确定至少一个DRX配置中DRX激活期在时域上的并集，也就是第一激活期，并向物理层指示，这里，至少一个DRX配置可以为第一通信设备能够确定的部分或者全部DRX配置，例如，至少一个DRX配置可以包括第一业务的DRX配置。然后，物理层在第一激活期内进行sensing，解调其他UE的SCI，并进行测量。例如，测量PSCCH-RSRP或者PSSCH-RSRP；或者，测量S-RSSI。其中PSCCH-RSRP是对PSCCH关联的DMRS测量确定的，PSSCH-RSRP是对PSSCH关联的DMRS测量确定的。当然，第一通信设备还可以对SCI指示的资源的其他参数进行测量，对此本申请实施例不做具体限定。
可以理解的，第一通信设备在第一激活期内监听SCI，那么，SCI是位于第一激活期内的，那么，第一通信设备对SCI进行测量，也可以认为是在第一激活期内进行测量。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，在第一通信设备进行S702对候选资源进行资源排除时，第一通信设备的MAC层先向物理层指示第一业务对应的DRX激活期的并集和/或第一业务中的当前业务及历史业务中非周期业务对应的DRX激活期的并集，然后，物理层从第二资源中排除资源，确定与上述并集存在交集的资源作为第一候选资源，可以理解的，第一候选资源需要满足以下至少一个条件：在时域上与第一业务对应的DRX激活期的并集存在交集；在时域上与第一业务中的当前业务及历史业务中非周期业务对应的DRX激活期的并集存在交集。
在一些可能的实施例中，物理层还可以进一步地从第一候选资源中执行如上述S702所述的方法来进一步地排除资源，以确定候选资源，进而确定第一资，本申请实施例不做具体限定。
需要说明的是，第二资源可以为物理层通过sensing确定的资源在选择窗中对应的资源，还可以为物理层从通过sensing确定的资源选择中执行S702进行资源排除后剩下的资源。
在本申请其他实施例中，图8为本申请实施例中的第一通信设备侧通信方法的第二流程示意图，参见图8所示，该方法。包括：
S801：第一通信设备确定第二激活期；
S802：第一通信设备在第二激活期内监听其他UE发送的SCI；
这里，SCI用于指示其他UE用于侧链路传输的资源。
在本申请中，第一通信设备的MAC层在确定第二激活期之后，向第一通信设备的物理层指示第二激活期，物理层在第二激活期内监听其他UE发送的SCI，进而物理层在第二激活期内进行测量。
在一些可能的实施方式中，首先，第一通信设备确定至少一个DRX配置中DRX激活期在时域上的并集，也就是第二激活期，这里，至少一个DRX配置可以为第一通信设备能够确定的部分或者全部DRX配置，例如，至少一个DRX配置可以包括第一业务的DRX配置。
进一步地，在S802之后，第一通信设备可以根据SCI，在第二激活期内进行测量，也就是对SCI进行测量。例如，测量PSCCH-RSRP或者PSSCH-RSRP；或者，测量S-RSSI。其中PSCCH-RSRP是对PSCCH关联的DMRS测量确定的，PSSCH-RSRP是对 PSSCH关联的DMRS测量确定的。当然，第一通信设备还可以对SCI的其他参数进行测量，对此本申请实施例不做具体限定。
可以理解的，第一通信设备在第二激活期内监听SCI，那么，SCI是位于第二激活期内的，那么，第一通信设备对SCI进行测量，也可以认为是在第二激活期内进行测量。
至此，第一通信设备完成在第二激活期内sensing。
S803：第一通信设备根据得到的测量结果，对SCI所指示资源进行资源排除，确定第一候选资源。
第一通信设备从SCI指示的资源中，将测量结果满足于某一个条件的资源排除，由此便可以得到第一通信设备的候选资源集，那么，第一通信设备在传输业务时可以在候选资源集中选择资源进行传输。例如，通过S801，第一通信设备对SCI进行参考信号接收功率的测量，确定PSCCH-RSRP或者PSSCH-RSRP，然后，第一通信设备可以将PSCCH-RSRP或者PSSCH-RSRP满足预设条件的资源排除，或者，第一通信设备可以根据SCI的指示，将其他UE占用的资源排除，再者，第一通信设备还可以其他UE占用的资源以及RSRP高于预设门限值的资源排除。
在实际应用中，上述预设条件可以为RSRP值在预设范围内，例如RSRP值在所有测量得到的RSRP值由大到小或者由小到大排序后前20％，或者，RSRP值高于所有RSRP值的低于70％，当然，上述预设条件还可以为其他条件，可以根据第一通信设备的传输优先级与其他UE的SCI中指示的传输优先级来设定，本申请实施例不做具体限定。
在一些可能的实施方式中，第一通信设备还可以通过S801解调SCI，确定资源的子载波间隔配置，第一通信设备还可以根据资源的子载波间隔配置，对资源进行筛选，使得选择的子载波间隔满足传输需求的资源，以供后续侧链路传输使用。
当然，第一通信设备可以根据其他条件进行资源排除，本申请不做具体限定。
S804：第一通信设备从第一候选资源中选取用于侧链路传输的第一资源；
在第一业务到来之后，第一通信设备可以从第一候选资源中针对第一业务选择预留资源，就是第一资源。
在本申请实施例中，上述第一业务可以包括：通信目标、侧链路连接、源和目标对、sidelink链路、逻辑信道、资源池、侧链路业务、MAC PDU、TB等其中的一个或者多个的组合，本申请实施例对此不做具体限定。
S805：第一通信设备对第一资源进行重新评估；
在进行业务传输之前，第一通信设备还会对第一资源进行重新评估，看通过S803选择的第一资源是否能够用于侧链路传输。例如，由于存在新业务到达、第一资源被其他UE占用等情况的发生，就可能导致之前选择的第一资源无法用于侧链路传输，所以，第一通信设备需要重新对选择的第一资源进行评估。
S806：若评估结果表示第一资源无法用于侧链路传输，则第一通信设备触发资源重选，返回S802；
S807：若评估结果表示第一资源可以用于侧链路传输，则第一通信设备在采用第一资源开始侧链路传输；
S808：在使用第一资源传输的过程中，第一通信设备判断是否触发资源重选；
第一通信设备在侧链路传输过程中，因为一些原因，可能会导致第一资源无法用于 侧链路传输，因此，第一通信设备还需要对第一资源进行评估，判断是否触发资源重选。例如，上述原因可以包括：上层配置或重配资源池；或，无configured sidelink gran；或，在过去一秒MAC实体在任何configured sidelink grant指示的资源上即无新传又无重传；或，配置了sl-ReselectAfter、且configured sidelink grant指示的连续未使用的传输机会达到sl-ReselectAfter；或，configured sidelink grant指示的传输资源不能满足根据对应的逻辑信道的优先级确定的某个逻辑信道上数据的时延要求，且MAC实体选择不进行相应单个MAC PDU的传输；或，UE收到的SCI指示的逻辑信道的优先级比待传数据的逻辑信道的优先级更高，该SCI调度的某个sl传输预期会与当前预留的某个资源重叠，且该SCI指示的sl传输的SL-RSRP测量结果高于门限。当第一资源满足如上述任意条件时，清除该SL process关联的预留资源(若有的话)，并触发第一通信设备资源选择/重选。
S809：若触发资源重选，则第一通信设备返回S802；
S810：若不触发资源重选，则第一通信设备继续使用第一资源进行侧链路传输。
在本申请实施例中，通过上述S801至S810所示的方法，第一通信设备选择与第一业务对应的DRX激活期存在交集(即第二激活期)的资源作为预留资源，并使用该预留资源进行侧链路传输，如此能够保证第一通信设备可以在激活期内接收到来自第二通信设备(如TX UE)的传输，节约RX UE的功耗，并保证第一通信设备与第二通信设备之间的侧链路传输。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，在S803之后，第一通信设备还可以确定用于侧链路传输的第一候选资源和第一业务；第一通信设备从第一候选资源中确定第一资源。
第一通信设备通过S803确定第一候选资源后，还可以获取自身当前可确定的第一业务。由于DRX配置是针对第一业务进行配置的，那么，第一通信设备可以从第一候选资源中，选择与第二激活期存在交集的资源作为第二候选资源，进而从第二选择资源中确定第一资源。此时，第一资源可以理解为预留资源。这里，第一业务可以包括当前业务和/或历史业务，“第一业务”如上所述，假设，以第一业务为destination ID标识的通信目标为例，第一通信设备可以确定至少一个destination ID作为候选destination ID集合，候选destination ID集合可以包括第一通信设备当前可选的destination ID，和/或历史可选的destination ID。
在本申请实施例中，为了实现资源与第一业务的DRX激活期匹配，上述第二激活期可以为一个destination ID对应的激活期或者多个destination ID对应的激活期。
那么，如果存在多个destination ID，第二激活期可以为多个destination ID对应的DRX配置中的多个DRX激活期的并集；那么，第一通信设备可以从第一候选资源中选择与该并集存在交集的资源作为第二候选资源，然后，第一通信设备还可以从第二候选资源中选择第一资源，例如，第一通信设备从第一候选资源中选择部分或者全部位于上述等多个DRX激活期所组成的并集中得到资源作为第二候选资源，再从第二候选资源中，根据选定的频域资源数及载波上允许的逻辑信道的可用侧链路数据的剩余PDB选定用于一次传输机会的时频资源，进一步还可以利用选定的时域资源，以确定好的资源预留周期再选定对应的周期性资源。
或者，如果存在一个destination ID，第二激活期可以为该destination ID对应的DRX配置中的多个DRX激活期，那么，第一通信设备可以选择在时域上与第一业务对应的DRX激活期的交集满足第一条件的资源作为第二候选资源。
在实际应用中，上述第一条件可以包括：在时域上与第一业务对应的DRX激活期的交集最大、在时域上与第一业务对应的DRX激活期的交集在预设范围内、在时域上与第一业务对应的DRX激活期的交集大于预设门限等中的一个或多个。例如，一个destination ID对应的DRX激活期为子帧0，那么，第一通信设备将第一候选资源中与子帧0的交集的符号数最大的资源确定为第二候选资源，或者，第一通信设备将第一候选资源中与子帧0的交集的符号数大于80％(即11个符号)的资源确定为第二候选资源，再者，第一通信设备将第一候选资源中在子帧0的符号1至符号12内的资源确定为第二候选资源。类似的，一个destination ID对应对的DRX激活期为子帧0、子帧3、子帧6，那么，第一通信设备将第一候选资源中分别与子帧0、子帧3、子帧6的交集为最大的多个资源确定为第二候选资源，或者，第一通信设备将第一候选资源中分别与子帧0、子帧3、子帧6的交集的符号数大于80％(即11个符号)的多个资源确定为第二候选资源，再者，第一通信设备将第一候选资源中分别位于子帧0、子帧3、子帧6的符号1至符号12内的多个资源确定为第二候选资源。当然，第一条件还可以为其他条件，本申请实施例不做具体限定。
在一些可能的实施方式中，第一通信设备执行S804选择的第一资源还可以作为候选资源，以供第一通信设备从候选资源中选取预留资源，进而执行S805至S810。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，在存在多个destination ID的场景下，第一通信设备在执行S807使用第一资源开始侧链路传输之前，还可以对第一业务，也就是destination ID进行选择，此时，第一通信设备可以从上述多个destination ID中选择对应的DRX激活期与第一资源在时域上存在交集的destination ID(用于标识第二业务)，也就是说，最后选择的destination ID对应的DRX激活期与预留资源在时域上存在交集。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，在第一通信设备进行S803对候选资源进行资源排除时，第一通信设备的MAC层先向物理层指示第一业务对应的DRX激活期的并集和/或第一业务中的当前业务及历史业务中非周期业务对应的DRX激活期的并集，然后，物理层从第二资源中进行资源排除，确定与上述并集存在交集的资源作为第三候选资源，也就是说，第三候选资源需要满足以下至少一个条件：在时域上与第一业务对应的DRX激活期的并集存在交集；在时域上与第一业务中的当前业务及历史业务中非周期业务对应的DRX激活期的并集存在交集。第三候选资源就可以作为上述第一候选资源，当然，物理层也可以进一步地从第三候选资源中执行如S803所述的方法来确定第一候选资源，本申请实施例不做具体限定。
在本申请中，第二资源可以为物理层通过sensing确定的资源在选择窗中对应的资源，还可以为物理层从通过sensing确定的资源选择中执行S702进行资源排除后剩下的资源。
在本申请其他实施例中，图9为本申请实施例中的第一通信设备侧通信方法的第三流程示意图，参见图9所示，该方法。包括：
S901：第一通信设备进行感知(sensing)；
第一通信设备持续监听其他UE发送的SCI，并按照SCI的指示，对SCI所指示的资源进行测量，确定测量结果。这里，第一通信设备监听到其他UE的SCI后，对SCI进行解调，解调的SCI至少可以反映出sidelink上资源的使用情况。
在本申请实施例中，上述“测量”可以包括基于sidelink DMRS的sidelink RSRP的测量，例如，测量PSCCH的RSRP(即PSCCH-RSRP)或者PSSCH-RSRP；或者，还可以测量S-RSSI等。其中PSCCH-RSRP是对PSCCH关联的DMRS测量确定的，PSSCH-RSRP是对PSSCH关联的DMRS测量确定的。当然，第一通信设备还可以对SCI指示的资源的其他参数进行测量，对此本申请实施例不做具体限定。
S902：第一通信设备确定第四资源；
在本申请实施例中，第四资源可以为在选择窗的资源，还可以为选择窗中的资源进行资源排除后剩下的资源。
S903：第一通信设备从第四资源中确定出第三候选资源；
这里，第三候选资源需要满足以下至少一个条件：在时域上与第一业务对应的DRX激活期的并集存在交集；在时域上与第一业务中当前业务及历史业务中非周期业务对应的DRX激活期的并集存在交集；
第一通信设备在进行S901之后，第一通信设备的MAC层先向物理层指示第一业务对应的DRX激活期的并集和/或第一业务中的当前业务及历史业务中非周期业务对应的DRX激活期的并集，也就是第一激活期，然后，物理层从第四资源中进行资源排除，确定与上述并集存在交集的资源作为第三候选资源，也就是说，第三候选资源需要满足以下至少一个条件：在时域上与第一业务对应的DRX激活期的并集存在交集；在时域上与第一业务中的当前业务及历史业务中非周期业务对应的DRX激活期的并集存在交集。那么，第三候选资源可以用于确定第五资资源。
当然，物理层还可以进一步地从第三候选资源中进一步排除资源，例如，第一通信设备从第三候选资源中，将测量结果满足于某一个条件的资源排除，将剩下的资源确定为第一通信设备的候选资源，进而第一通信设备还可以在传输第一业务时从候选资源中确定第五资源进行传输。例如，通过S902，第一通信设备对SCI进行参考信号接收功率的测量，确定PSCCH-RSRP或者PSSCH-RSRP，然后，第一通信设备可以将PSCCH-RSRP或者PSSCH-RSRP满足预设条件的资源排除，或者，第一通信设备可以根据SCI的指示，将其他UE占用的资源排除，再者，第一通信设备还可以其他UE占用的资源、且相应RSRP高于预设门限值的资源排除。
在实际应用中，上述预设条件可以为RSRP值在预设范围内，例如RSRP值在所有测量得到的RSRP值由大到小或者由小到大排序后前20％，或者，RSRP值高于所有RSRP值的70％，当然，上述预设条件还可以为其他条件，可以根据第一通信设备的传输优先级与其他UE的SCI中指示的传输优先级来设定，本申请实施例不做具体限定。

S905：第一通信设备对第五资源进行重新评估；
在进行业务传输之前，第一通信设备还会对第五资源进行重新评估，看通过S903选择的第五资源是否能够用于侧链路传输，以保证最终选择的资源是可以用于侧链路传输的。
S906：若评估结果表示第五资源无法用于侧链路传输，则第一通信设备触发资源重选，返回S902；
S907：若评估结果表示第五资源可以用于侧链路传输，则第一通信设备在采用第五资源开始侧链路传输；
S908：在使用第五资源传输的过程中，第一通信设备持续判断是否触发资源重选；
在S905和S908中，第一通信设备在侧链路传输过程中，因为一些原因，可能会导致第一资源无法用于侧链路传输，因此，第一通信设备还需要对第一资源进行评估，判断是否触发资源重选。例如，上述原因可以包括：上层配置或重配资源池；或，无configured sidelink gran；或，在过去一秒MAC实体在任何configured sidelink grant指示的资源上即无新传又无重传；或，配置了sl-ReselectAfter、且configured sidelink grant指示的连续未使用的传输机会达到sl-ReselectAfter；或，configured sidelink grant指示的传输资源不能满足根据对应的逻辑信道的优先级确定的某个逻辑信道上数据的时延要求，且MAC实体选择不进行相应单个MAC PDU的传输；或，UE收到的SCI指示的逻辑信道的优先级比待传数据的逻辑信道的优先级更高，该SCI调度的某个sl传输预期会与当前预留的某个资源重叠，且该SCI指示的sl传输的SL-RSRP测量结果高于门限。当第一资源满足如上述任意条件时，清除该SL process关联的预留资源(若有的话)，并触发第一通信设备资源选择/重选。
S909：若触发资源重选，则第一通信设备返回S902；
S910：若不触发资源重选，则第一通信设备继续使用第五资源进行侧链路传输。
在本申请实施例中，通过上述S901至S910所示的方法，第一通信设备选择与第一业务对应的DRX激活期存在交集的资源作为预留资源，并使用该预留资源进行侧链路传输，如此能够保证第一通信设备可以在激活期内接收到来自第二通信设备(如TX UE)的传输，节约RX UE的功耗，并保证第一通信设备与第二通信设备之间的侧链路传输。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，第一通信设备在执行S901时，首先，确定至少一个DRX配置中DRX激活期在时域上的并集，也就是第一激活期，这里，至少一个DRX配置可以为第一通信设备能够确定的部分或者全部DRX配置，例如，至少一个DRX配置可以包括第一业务的DRX配置。然后，第一通信设备在第一激活期内进行sensing，解调其他UE的SCI，并对SCI进行测量。例如，测量PSCCH-RSRP或者PSSCH-RSRP；或者，测量S-RSSI。其中PSCCH- RSRP是对PSCCH关联的DMRS测量确定的，PSSCH-RSRP是对PSSCH关联的DMRS测量确定的。当然，第一通信设备还可以对SCI指示的资源的其他参数进行测量，对此本申请实施例不做具体限定。
在本申请实施例中，第一通信设备的MAC层在确定第一激活期之后，向第一通信设备的物理层指示第一激活期，物理层在第一激活期内监听其他UE发送的SCI，进而物理层在第一激活期内进行测量。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，在S903之后，第一通信设备还可以确定用于侧链路传输的第三候选资源和第一业务；第一通信设备从第三候选资源中确定第五资源。
第一通信设备通过S903确定第三候选资源后，还可以获取自身当前可确定的第一业务。由于DRX配置是针对第一业务进行配置的，那么，第一通信设备可以从第三候选资源中，选择与第一激活期存在交集的资源作为第五资源。此时，第五资源可以为预留资源。这里，第一业务可以包括当前业务和/或历史业务，“第一业务”如上所述，假设，以第一业务为destination ID标识的通信目标为例，第一通信设备可以确定至少一个destination ID作为候选destination ID集合，候选destination ID集合可以包括第一通信设备当前可选的destination ID，和/或历史可选的destination ID。
在本申请实施例中，为了实现资源与第一业务的DRX激活期匹配，上述第一激活期可以为一个destination ID对应的激活期或者多个destination ID对应的激活期的并集。
那么，如果存在多个destination ID，第一激活期可以为多个destination ID对应的DRX配置中的多个DRX激活期的并集；那么，第一通信设备可以从第三候选资源中选择与该并集存在交集的资源作为第四候选资源，然后，第一通信设备还可以从第四候选资源中选择第五资源，例如，第一通信设备从第三候选资源中选择部分或者全部位于上述等多个DRX激活期所组成的并集中得到资源作为第四候选资源，再从第四候选资源中，根据选定的频域资源数及载波上允许的逻辑信道的可用侧链路数据的剩余PDB选定用于一次传输机会的时频资源，进一步还可以利用选定的时域资源，以确定好的资源预留周期再选定对应的周期性资源。
或者，如果存在一个destination ID，第一激活期可以为该destination ID对应的DRX配置中的多个DRX激活期，那么，第一通信设备可以选择在时域上与第一业务对应的DRX激活期的交集满足第一条件的资源作为第四候选资源。
在实际应用中，上述第一条件可以包括以下一个或者多个：在时域上与第一业务对应的DRX激活期的交集最大、在时域上与第一业务对应的DRX激活期的交集在预设范围内、在时域上与第一业务对应的DRX激活期的交集大于预设门限等。
在一些可能的实施方式中，第一通信设备执行S904选择的第五资源还可以作为候选资源，以供第一通信设备从候选资源中选取预留资源，进而执行S905至S910。
在一些可能的实施方式中，为了提高预留资源与第一业务的DRX激活期的匹配程度，在多个destination ID的场景下，第一通信设备在执行S907使用第五资源开始侧链路传输之前，还可以对destination ID进行选择，此时，第一通信设备可以从上述多个destination ID中选择对应的DRX激活期与第五资源在时域上存在交集的destination ID (用于标识第二业务)，也就是说，最后选择的destination ID对应的DRX激活期与预留资源在时域上存在交集。
在本申请实施例中，在上述一个或者多个实施例中，第一通信设备可以持续对第三资源(即第一通信设备选择的预留资源)进行评估，若第一通信设备确定第三资源与第一通信设备的当前业务(第三业务或者第四业务)对应的DRX激活期不存在交集，也就是说，第三资源在时域上位于当前业务对应的DRX激活期之外，那么，第一通信设备触发资源重选，以重新选择与第当前业务的DRX激活期存在交集的资源。
需要说明的是，当前业务是第一通信设备对第三资源进行评估时的业务，可以与第一业务可以相同，也可以与第一业务不相同。例如，第三业务可以包括：通信目标、侧链路连接、源和目标对、sidelink链路、逻辑信道、资源池、侧链路业务、MAC PDU、TB等其中的一个或者多个的组合，本申请实施例对此不做具体限定。第四业务可以包括：可以包括：通信目标、侧链路连接、源和目标对、sidelink链路、逻辑信道、资源池、侧链路业务、MAC PDU、TB等其中的一个或者多个的组合，本申请实施例对此不做具体限定。
第一通信设备在进行侧链路传输的过程中，由于业务发生变化，如有新业务到达、当前资源池发生变化、当前资源发生重配等，导致第三资源无法用于侧链路传输，例如，第三资源不满足第一业务的时延要求，此时，第一通信设备可以触发资源重选。进一步地，第一通信设备还可以考虑第三资源与当前业务的DRX激活期的关系，来决定是否触发资源重选。
举例来说，图10为本申请实施例中的资源与当前业务对应的DRX激活期的示意图，参见图10所示，当前业务在t1时刻到达，第三资源的开始时间t2与t1之间的时间差满足当前业务的时延要求，但是，由于第三资源位于当前业务对应的DRX激活期之外，即第三资源与当前业务对应的DRX激活期不存在交集，此时，第一通信设备触发资源重选。
在一些可能的实施方式中，上述第三资源与第一通信设备的当前业务对应的DRX激活期不存在交集，可以包括：第三资源与当前业务对应的多个DRX激活期的并集不存在交集；或者，第三资源与当前业务对应的多个DRX激活期中的至少一个DRX激活期不存在交集；或者，第三资源与当前业务对应的多个DRX激活期中满足预设数量的DRX激活期不存在交集。可以理解的，当前业务对应的多个DRX激活期中与第三资源不存在交集的DRX激活期达到预设数量(可以为经验值)，或者在预设数量范围(可以为经验值)内，第一通信设备确定第三资源与当前业务对应的多个DRX激活期中满足预设数量的DRX激活期不存在交集。
在一些可能的实施方式中，第一通信设备还可以为第一资源配置周期，那么，第一通信设备可以将第一业务对应的DRX配置中满足第二条件的DRX周期(即DRX cycle)配置为第一资源对应的周期。
这里，第二条件可以包括：第一业务对应的DRX配置中DRX周期的最小值、第一业务对应的DRX配置中DRX周期小于预设门限、第一业务对应的DRX配置中DRX周期小于20％等，第二条件还可以为其他条件，本申请实施例不做具体限定。
需要说明的是，第一通信设备为第一资源配置周期与第一通信设备选择第一资源并 无执行的先后顺序，两者可以先后执行，也可以同时执行。当两者先后执行时，第一通信设备可以先为第一资源配置周期再选择第一资源，也可以先选择第一资源再为第一资源配置周期。对于第一通信设备为第一资源配置周期与第一通信设备选择第一资源的执行时机，本申请实施例不做具体限定。
在本申请实施例中，通过将第一资源的周期选取为第一业务对应的所有DRX配置的周期的最小值，以使得第一通信设备醒来监听SCI的周期与第一业务发送的周期相匹配，从而提升了侧链路资源被有效利用的概率。
本申请实施例还提供一种通信方法，可以应用于上述通信系统，其中，第一通信设备可以为TX UE，也可以为RX UE，相应地，第二通信设备可以为RX UE，也可以为TX UE。
图11为本申请实施例中的通信方法的流程示意图，参见图11所示，该方法可以包括：
S1101：第一通信设备确定第一资源池或第一资源池中的资源满足第三条件；
这里，第一资源池是第一通信设备当前进行资源选择的资源池；
在一些可能的实施方式中，第三条件包括：当前资源池的信道拥塞率(channel busy ratio，CBR)满足第四条件，如第四条件可以为CBR大于预设值(可以经验值)或者CBR在预设范围内、第一通信设备触发资源池重选和/或丢包率满足第五条件，如第五条件可以为丢包率大于预设值(可以经验值)，或者丢包率在预设范围内等。
在一些可能的实施方式中，第三条件还可以包括以下一个条件或者多个条件的组合：CBR满足第四条件达到第一阈值、第一通信设备触发资源池重选的次数达到第二阈值、第二通信设备的丢包率满足第五条件的次数达到第三阈值。其中，第一阈值、第二阈值以及第三阈值可以为经验值，如3次、5次、8次。
在本申请实施例中，第三条件不限于上述几种情况，对此不做具体限定。
S1102：第一通信设备进行DRX配置；
第一通信设备在执行S1101之后，执行S1102,，以使得第一通信设备选择能够用于侧链路传输的资源池。
S1103：第一通信设备指示第二通信设备进行DRX配置。
需要说明的是，这里所说的“DRX配置”可以理解为根据预留资源进行DRX配置，例如，根据预留资源进行DRX重配，使得预留资源在时域上与重配后的DRX激活期存在交集；或者，根据预留资源进行DRX初配，使得预留资源在时域上与配置的DRX激活期存在交集。
在一些可能的实施方式中，上述“DRX配置”还可以理解为使能(enable)或者去使能(disabled)DRX功能，也就是说第一通信设备可以指示第二通信设备配置DRX功能或者取消DRX功能。进一步地，如果第一通信设备指示第二通信设备配置DRX功能，那么，第一通信设备可以同时向第二通信设备发送DRX配置信息，或者，由第二通信设备自行配置DRX配置信息，当然，第二通信设备还可以通过其他方式确定DRX配置信息，对此，本申请实施例不做具体限定。
在本申请其他实施例中，第一通信设备在执行S1101之后，还可以执行S1103，以指示第二通信设备选择能够用于侧链路传输的资源池。
在一些可能的实施方式中，S1103可以包括：第一指示消息用于向第二通信设备通知第一通信设备的当前资源池或当前资源池中的资源满足第三条件；或者，第一通信设备向第二通信设备发送第二指示消息，第二指示消息用于指示第二通信设备进行DRX配置；和/或，第一通信设备向第二通信设备发送第三指示消息，第三指示消息用于指示DRX配置信息。
在实际应用中，DRX配置信息可以包括部分或者全部的侧链路DRX参数。可选的，DRX参数可以包括以下一个或多个参数：SL DRX持续时间定时器(drx-onDurationTimerSL)、SL DRX时隙补偿(drx-SlotOffsetSL)、SL DRX静止定时器(drx-InactivityTimerSL)、SL DRX重传定时器(drx-RetransmissionTimerSL)、SL DRX长周期起始补偿(drx-LongCycleStartOffsetSL)、SL DRX长周期(drx-LongCycleSL)、SL DRX短周期(drx-ShortCycleSL)、SL DRX短周期定时器(drx-ShortCycleTimerSL)或者SL DRX HARQ往返时延(round trip time，RTT)定时器(drx-HARQ-RTT-TimerSL)。这里，可以理解的上述参数中所说的“定时器”实际上是指该定时器的长度。
在本申请其他实施例中，如果第一通信设备为TX UE，那么，在S1101之前，第一通信设备还可以接收来自第二通信设备(RX UE)的第四指示消息，第四指示消息用于指示第二通信设的丢包率或者丢包率满足第五条件，例如，第五条件可以为丢包率大于预设值(可以经验值)，或者丢包率在预设范围内。当然，第五条件还可以为其他条件，本申请实施例不做具体限定。
在一些可能的实施方式中，第二通信设备还可以在丢包率满足第五条件达到第四阈值，如丢包率满足第五条件达到3次、5次或者10次，第二通信设备向第一通信设备发送第四指示信息，此时第四指示信息可以用于指示最近一次的丢包率或者最近一次的丢包率满足第五条件。在实际应用中，第二通信设备发送第四指示信息的触发条件还可以为其他条件，本申请实施例不做具体限定。
基于相同的发明构思，本申请实施例提供一种通信装置，该通信装置可以为第一通信设备中的芯片或者片上系统，还可以为第一通信设备中用于实现上述任一实施例所述方法的功能模块。该芯片或者片上系统包括存储器，存储器中存储有指令，当指令被片上系统或者芯片调用的时候，执行上述方法。图12为本申请实施例中的通信装置的一种结构示意图，参见图12所示，该通信装置1200可以包括：确定模块1201；还可以包括触发模块1202、监听模块1203、配置模块1204或者指示模块1205中的一个或者多个。

基于相同的发明构思，本申请实施例提供一种通信装置，可以应用于上述通信系 统。该通信装置可以与上述一个或者多个实施例所述的第一通信设备一致。图13为本申请实施例中的通信装置的另一种结构示意图，参见图13所示，该通信装置1300可以包括：包括处理器1301、存储器1302、总线1303、输入设备1304、输出设备1305。
具体的，存储器1302可以包括以易失性和/或非易失性存储器形式的计算机存储媒体，如只读存储器和/或随机存取存储器。存储器1302可以存储操作系统、应用程序、其他程序模块、可执行代码、程序数据、用户开户数据、用户订阅数据等。

第一通信设备可以通过网络接口1306连接到网络中，例如连接到局域网(local area network，LAN)。在联网环境下，第一通信设备中存储的计算机执行指令可以存储在远程存储设备中，而不限于在本地存储。
当第一通信设备中的处理器1301执行存储器1302中存储的可执行代码或应用程序时，可以执行以上实施例中的第一通信设备一侧的方法步骤，具体执行过程参见上述实施例，在此不再赘述。

基于相同的发明构思，在本申请实施例还提供一种通信方法，该方法可以应用于一通信系统，图14为本申请实施例中的通信系统的又一种架构示意图，参见图14所示，该通信系统10可以包括：第一通信设备141、第二通信设备142以及第三通信设备143，其中，针对不同的应用场景，第一通信设备可以为发送终端设备(记为TX UE)或接收终端设备(记为RX UE)，第二通信设备可以为TX UE、RX UE、TX UE所属的网络设备(如基站)或RX UE所属的网络设备(如基站)，第三通信设备也可以为TX UE、RX UE、TX UE所属的网络设备(如基站)或RX UE所属的网络设备(如基站)。
在侧链路传输的过程中，上述第一通信设备可以收到第二通信设备为第一通信设备对应的第一侧链路配置的第一DRX配置信息，还可以收到第三通信设备为第一通信设备对应的第二侧链路配置的第一资源配置信息。其中，第一DRX配置信息可以包括部分或者全部的侧链路DRX参数。进一步地，第一DRX配置信息用于指示第一侧链路的DRX激活时段，例如，DRX激活时段可以包括：DRX激活期(onduration)或者活动时长(active time)。这里，活动时长可以包括激活定时器(onduration timer)的时长、重传定时器(retransmission timer)的时长、静止定时器(inactivity timer)的时长等，当然，active time还包括其他时段，本申请实施例不做 具体限定。
在一些可能的实施方式中，第一侧链路可以为第一通信设备与第二通信设备之间的侧链路，也可以为第一通信设备与其他终端设备(可以记为其他UE)之间的侧链路。那么，第一DRX配置信息可以用于第一通信设备与第二通信设备之间的第一侧链路，还可以用于第一通信设备与其他UE之间的第一侧链路。
在一些可能的实施方式中，第一侧链路可以为一条或者多条侧链路，第二侧链路也可以为一条或者多条侧链路。需要注意的是，当第一侧链路为一条侧链路时，第二侧链路与第一侧链路可以为同一侧链路，或者第二侧链路与第一侧链路为不同侧链路，例如，第一侧链路为TX UE与RX UE之间的侧链路，而第二侧链路可以为RX UE与TX UE之间的侧链路，也可以为RX UE作为TX UE与其他RX UE之间的侧链路。第一侧链路还可以为TX UE或者RX UE与其他UE之间的侧链路，而第二侧链路可以为RX UE与TX UE之间的侧链路，也可以为TX UE或者RX UE与其他UE之间的侧链路。进一步地，当第一侧链路为多条侧链路时，第二侧链路可以为第一侧链路中的一条或者多条，也就是说，第二侧链路为第一侧链路中的部分侧链路或者全部侧链路。
在本申请实施例中，第一通信设备可以为自身配置第一DRX配置信息，而第三通信设备为第一通信设备配置第一资源配置信息；或者，第二通信设备可以为第一通信设备配置第一DRX配置信息，第一通信设备为自身配置第一资源配置信息；或者，第二通信设备可以为第一通信设备配置第一DRX配置信息，第三通信设备为第一通信设备配置第一资源配置信息。可见，由于DRX配置信息和资源配置信息是由不同的主体进行配置的，那么，DRX配置信息所指示的DRX激活时段与资源配置信息所指示的时间区域可能会在一个或者多个时间段内存在冲突，例如，参见图6所示，DRX激活期与时域区间没有交集，或者，参见图5所示，DRX激活期与时区间的交集小于某一与阈值，此时，可以称为DRX配置信息与资源配置信息不匹配。在本申请实施例中，上述“一个时间段”可以指已发生的时域区间对应的时隙，也可以指未发生的时域区间对应的时隙。
进一步地，对于mode1来说，上述时域区间可以为基站为UE配置的资源对应的时域区间；对于mode2来说，上述时域区间可以为基站为UE配置的资源池、对端UE为UE配置的资源池或者UE自己选择的资源池中的时域区间。在实际应用中，上述时域区间可以采用符号(symbol)、时隙(slot)、子帧、系统帧、超帧等表示。
具体来说，如果n个DRX激活时段(由DRX配置信息指示的)与时域区间(由资源配置信息指示的)重叠的时隙数小于预设阈值(如n个onduration与时域区间的总重叠时隙数＜b)，则可以认为DRX激活时段与时域区间在一个时间段内存在冲突；或者，n个DRX激活时段与时域区间重叠的时隙数除以n倍的DRX激活期的时隙数小于预设阈值(如n个onduration与时域区间的总重叠时隙数/(n×onduration时隙数)＜a)，则可以认为DRX激活时段与时域区间在一个时间段内存在冲突。其中，上述参数n、a、b可以由网络根据资源池的CBR、业务特性等因素确定，并通过系统信息、RRC消息或者MAC CE/SCI配置或者预配置；或者，n的取值也可定义 为(onduration的时隙数与时域区间的位图(bitmap)的长度的最小公倍数)/onduration的时隙数。当然，上述参数n、a、b还可以存在其他的取值情况，本申请实施例不做具体限定。
结合上述通信系统，本申请提供一种通信方法。在该通信方法中，若第一DRX配置信息与第一资源配置信息不匹配，则第一通信设备向第二通信设备发送第一信息，和/或向第三通信设备发送第二信息。也就是说，若第一DRX配置信息指示的激活时段与第一资源配置信息所指示的时域区间在至少一个时间段内存在冲突，则第一通信设备向第二通信设备(为第一通信设备配置DRX配置信息的主体)发送第一信息，以请求第二通信设备为第一通信设备的第一侧链路配置(可以是初次配置，也可以是重新配置)DRX配置信息(此时，第一资源配置信息可以为第一通信设备自己配置的，也可以是第三通信设备为第一通信设备配置的)；或者，若第一DRX配置信息指示的激活时段与第一资源配置信息所指示的时域区间在至少一个时间段内存在冲突，则第一通信设备向第三通信设备(为第一通信设备配置资源配置信息的主体)发送第二信息，以请求第三通信设备为第一通信设备的第二侧链路配置(可以是初次配置，也可以是重新配置)资源配置信息(此时，第一DRX配置信息可以为第二通信设备为第一通信设备配置的，也可以是第一通信设备自己配置的)。在一些可能的实施方式中，上述第一资源配置信息可以为当前的资源配置信息，第一DRX配置信息可以为第一通信设备收到的DRX配置信息。那么，图15为本申请实施例中的第一通信设备侧通信方法的第四流程示意图，参见图15中实线所示，该方法包括：
S1501：第一通信设备接收来自第二通信设备的第一DRX配置信息；
这里，第一通信设备接收第二通信设备为第一侧链路配置的第一DRX配置信息。
S1502：第一通信设备判断第一DRX配置信息与第一资源配置信息是否匹配；若是，流程结束，若否，执行S1504；
其中，第一资源配置信息可以为第一通信设备当前的资源配置信息。
这里，第一通信设备在通过S1501接收到第一DRX配置信息之后，判断第一DRX配置信息与第一通信设备当前的资源配置信息(即第一资源配置信息)是否匹配。
示例性地，参见图15中虚线所示，在S1501之前，上述方法还可以包括：S1503：第一通信设备接收来自第三通信设备的第一资源配置信息。
这里，第一通信设备接收第三通信设备为第二侧链路配置的第一资源配置信息，然后，第一通信设备可以按照第一资源配置信息确定第二侧链路对应的时域区间。接下来，第一通信设备可以在该时域区间上进行第二侧链路传输。此时，第一资源配置信息可以理解为第一通信设备当前的资源配置信息。
S1504：第一通信设备向第二通信设备发送第一信息，和/或第一通信设备向第三通信设备发送第二信息。
在本申请实施例中，第一通信设备在判断DRX配置信息与当前的资源配置信息不匹配的时候，可以向第二通信设备请求进行DRX配置，和/或向第三通信设备请求进行资源配置，使得DRX配置信息与资源配置信息相匹配。
下面以具体场景为例，对上述通信方法进行说明。
第一种情况，第一通信设备为TX UE，第二通信设备为RX UE，第三通信设备为 TX UE所属的网络设备(如基站)。图16为本申请实施例中的资源配置和DRX配置的第一种场景示意图，参见图16所示，RX UE或者RX UE所属的基站为TX UE配置第一DRX配置信息，TX UE或者TX UE所属的基站为TX UE配置第一资源配置信息。其中，第一DRX配置信息可以用于RX UE与TX UE之间的第一侧链路，还可以用于RX UE与其他UE之间的第一侧链路，第一资源配置信息可以用于指示mode1中基站为TX UE配置的资源，也可以用于指示mode2中TX UE对应的资源池。
可以理解的，在第一种情况中，TX UE可以自己确定第一资源配置信息，那么，TX UE在通过S1501收到来自RX UE的第一DRX配置信息后执行S1502，进而当第一DRX配置信息与第一资源配置信息不匹配时执行S1504，此时，示例性的，TX UE可以向RX UE发送第一信息或者自行重新确定资源配配置信息。或者，TX UE所属的基站可以为TX UE配置第一资源配置信息，那么，TX UE在通过S1501收到来自RX UE的第一DRX配置信息后执行S1502，进而当第一DRX配置信息与第一资源配置信息不匹配时执行S1504，此时，示例性的，TX UE可以向RX UE发送第一信息和/或向TX UE自身所属基站发送第二信息。
在一些可能的实施方式中，上述S1504可以且不限于包括以下几种具体实施方式：

具体实施方式二：在RX UE所属的基站为TX UE配置第一DRX配置信息的情况下，TX UE向RX UE发送DRX配置失败信息(如第一信息)，然后，RX UE向自身所属的基站发送第四信息，以向RX UE所属的基站指示第一侧链路对应的DRX配置失败，使得基站在接收DRX配置失败信息到后，可以根据第四信息中携带的第一DRX配置信息对应的标识信息为第一侧链路配置或者重新配置DRX配置信息。
这里，第四信息可以为上述DRX配置失败信息，即RX UE向自身所属的基站转发DRX配置失败信息，或者，第四信息还可以包括RX UE基于DRX配置失败信息生成的指示信息，以指示第一侧链路对应的DRX配置失败。
上述DRX配置失败信息或者第四信息可以包括以下至少一种：用于表示DRX配置失败的第三信息(如表示失败原因为SL DRX配置冲突的信息)、第一DRX配置信息对应的标识信息、用于表示DRX配置信息与资源配置信息不匹配的配置失败类型、不允许RX UE为TX UE配置DRX的有效时长、第一资源配置信息(可以理解为发生冲突的资源配置信息)、期望的DRX配置信息(可以理解为建议的DRX配置信息，期望的DRX配置信息可以包括如DRX激活时段等部分DRX参数或者包括全部DRX参数)、DRX调整量以及对应的标识信息。当然，DRX配置失败信息还可以包括其他信息，本申请实施例不做具体限定。

进一步地，在RX UE所属的基站为TX UE配置第一DRX配置信息的情况下，RX UE还可以向自身所属的基站发送第四信息，以向RX UE所属的基站指示第一侧链路对应的DRX配置失败，使得基站在接收DRX配置失败信息到后，可以根据第四信息中携带的第一DRX配置信息对应的标识信息为第一侧链路配置或者重新配置DRX配置信息。
