For example, after the base station sends the DRX configuration information to the terminal device through RRC or MAC CE, the terminal device needs to combine the DRX configuration information and the actual packet incoming situation to determine the activation time or end activation time. That is to say, the possible activation time of the terminal equipment can only be inferred purely based on the DRX configuration, but it is usually difficult to know the actual packet incoming situation in advance.

本申请实施例中的基站可以是用于与终端设备通信的设备，该基站也可以称为接入网设备或无线接入网设备。本申请实施例中的基站可以是指将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称，或与如下名称进行替换，比如：节点B(NodeB)、演进型基站(evolved NodeB，eNB)、下一代基站(next generation NodeB，gNB)、中继站、接入点、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont，AP)、传输节点、收发节点、基带单元(base band unit，BBU)、射频拉远单元(Remote Radio Unit，RRU)、有源天线单元(active antenna unit，AAU)、射频头(remote radio head，RRH)、中心单元(central unit，CU)、分布式单元(distributed unit，DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物，或其组合。基站还可以指用于设置于前述设备或装置内的通信模块、调制解调器或芯片。基站还可以是移动交换中心以及设备到设备D2D、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备、6G网络中的网络侧设备、未来的通信系统中承担基站功能的设备等。基站可以支持相同或不同接入技术的网络。本申请的实施例对基站所采用的具体技术和具体设备形态不做限定。
基站可以是固定的，也可以是移动的。例如，直升机或无人机可以被配置成充当移动基站，一个或多个小区可以根据该移动基站的位置移动。在其他示例中，直升机或无人机可以被配置成用作与另一基站通信的设备。

基站和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和卫星上。本申请实施例中对基站和终端设备所处的场景不做限定。
通信系统中的定位技术
参见图2，通信系统100还可以包括定位设备130。该定位设备130可用于确定终端设备的位置信息。该定位设备130可以位于核心网。该定位设备130有时也可称为定位服务器。以NR系统为例，该定位设备130可以是定位管理功能(location management function，LMF)。以其他通信系统为例，该定位设备130可以是定位管理单元(location management unit，LMU)，定位管理中心(location management center，LMC)或演进服务移动位置中 心(evolved serving mobile location center，E-SMLC)。可以理解的是，该定位设备130还可以是其他用于确定终端设备的位置信息的网元、节点或设备，如可以是未来的通信系统中的用于确定终端设备的位置信息的网元或节点，本申请实施例对定位设备的名称不作具体限定。
通信系统100中的定位包括上行定位和下行定位。某些通信系统(如NR系统)基于定位参考信号(positioning reference signal，PRS)进行下行定位。PRS也可称为下行定位参考信号(downlink positioning reference signal，DL-PRS)，是用于定位功能的一种参考信号。例如，在下行定位过程中，终端设备120首先可以测量服务小区和邻区(或称相邻小区)发送的PRS，并估计出定位测量的相关信息。然后，终端设备120可以将定位测量的相关信息作为PRS的测量结果上报至定位设备130。定位设备130可以根据终端设备120上报的定位测量相关信息对终端设备120的位置进行解算，从而得到终端设备120的位置信息。例如，定位设备130可以基于三边定位法或三角定位法，计算终端设备120的位置信息。
某些通信系统(如NR系统)基于SRS进行上行定位。例如，在上行定位过程中，终端设备120发送SRS。基站110(服务小区的基站和邻区的基站)可以根据终端发送的SRS，得到测量结果。该SRS的测量结果可以包括定位测量的相关信息。然后，基站110可以将定位测量的相关信息发送至定位设备130。定位设备130可以根据基站110上报的定位测量相关信息对终端设备120的位置进行解算，从而得到终端设备120的位置信息。例如，定位设备130可以基于三边定位法或三角定位法，计算终端设备120的位置信息。
上述定位测量的相关信息可以包括以下信息中的一种或多种：时间信息、距离信息、功率信息、角度信息。更为具体地，定位测量的相关信息可以包括以下信息中的一种或多种：到达时间差(time difference of arrival，TDOA)、到达角度差(angle difference of arrival，ADOA)、参考信号接收功率(reference signal receive power，RSRP)等。
DRX模式
图3是DRX周期(DRX cycle)的示意图。如图3所示，T1为终端设备唤醒时间，或称DRX持续时间(on duration)。T2为终端设备的休眠时间，或称DRX机会(opportunity for DRX)。
终端设备的唤醒时间的时间长度可以由DRX持续时间定时器(drx-onDurationTimer)来控制。该DRX持续时间定时器的计时时长即为T1。终端设备在唤醒时间T1内需要持续监测物理下行控制信道(physical downlink control channel，PDCCH)，而在休眠时间T2内可以不进行PDCCH的监测。可以理解的是，T2时间越长，终端设备的能耗越低。
从图3中可以看出，对于长DRX周期(long DRX cycle)，终端设备唤醒的频率较低，因此对于终端设备来说更加省电；而对于短DRX周期(short DRX cycle)，终端设备的唤醒频率较高，会增加终端设备的能耗，但是可以提高基站成功调度终端设备的概率，减少数据传输时延。
每个媒质访问控制(medium access control，MAC)实体对应一个DRX配置。该DRX配置中可以包括上述DRX持续时间定时器。此外，DRX配置中还可以包括其他DRX定时器，从而共同用来调整终端设备的唤醒时间。
这里提及的其他DRX定时器例如可以包括以下定时器中的一种或多种：DRX去激活定时器(drx-InactivityTimer)、短DRX周期定时器(drx-ShortCycleTimer)、DRX下行重传定时器(drx-RetransmissionTimerDL)、DRX下行混合自动重传请求(hybrid automatic repeat reQuest，HARQ)往返时间(round-trip time，RTT)定时器(HARQ-RTT-TimerDL)。
DRX去激活定时器可以表示当终端设备成功检测到PDCCH以后，还需要继续监测多长时间。短DRX周期定时器可以表示终端设备遵循短DRX周期的持续时长。DRX下行重传定时器可用于终端设备接收下行重传调度，该定时器可表示终端设备为了接收期望的下行重传调度需要连续进行监测的时长。DRX下行混合自动重传请求往返时间(round- trip time，RTT)定时器(HARQ-RTT-TimerDL)用于终端设备接收下行重传调度，表示终端设备收到期望的下行重传调度前所需要等待的时长。
此外，基站还可以为终端设备配置其他DRX参数，例如短DRX周期、长DRX周期以及DRX起始子帧偏移量(drx-LongCycleStartOffset)、DRX时隙偏移量(drx-SlotOffset)等；以及配置其他DRX定时器，例如随机接入竞争解决定时器(ra-ContentionResolutionTimer)、DRX上行重传定时器(drx-RetransmissionTimerUL)、DRX上行HARQ往返时间定时器(HARQ-RTT-TimerUL)等。
在DRX机制中，长DRX周期的配置可以是默认配置，短DRX周期的配置可以是可选配置。对于配置了短DRX周期的终端设备，长DRX周期和短DRX周期之间可以通过以下方式进行转换：
当满足以下任意条件时，终端设备使用短DRX周期：1、DRX去激活定时器(drx-InactivityTimer)超时；2、终端设备收到DRX命令MAC CE(DRX Command MAC CE)；
当满足以下任意条件时，终端设备使用长DRX周期：1、短DRX周期定时器(Drx-shortCycleTimer)超时；2、终端设备收到长DRX命令MCA CE(long DRX command MAC CE)。
无论是长DRX周期还是短DRX周期，如果出现以下情况中的一种或多种，则终端设备处于DRX激活状态(有时也可称为DRX on态)，DRX激活状态对应时间可以称为DRX的激活时间(active time)。
情况1、DRX持续时间定时器、DRX去激活定时器、DRX下行重传定时器、DRX上行重传定时器和随机接入竞争解决定时器中的任意一个定时器正在运行；
情况2、终端设备在PUCCH上发送了(scheduling request，SR)且挂起(pending)；
情况3、终端设备的HARQ缓存(buffer)存在数据，并等待用于HARQ重传的上行授权(UL grant)；
情况4、终端设备成功接收响应于未由MAC实体选择的前导码(preamble)的随机接入响应(random access response，RAR)，却没有收到指示初传的使用该MAC实体的小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)的PDCCH。
在DRX周期中，除了DRX的激活时间，剩余的时间可以称为DRX的去激活时间(inactive time)或休眠时间。在休眠时间内，终端设备处于休眠状态(有时也可称为DRX off态)。
DRX模式下的定位
终端设备处于休眠状态时，当前协议规定该终端设备不允许发送周期性SRS和半持续SRS(semi-persistent SRS)，但可以发送非周期性SRS。此外，当终端设备处于休眠状态时，当前协议并未限制终端设备对PRS进行测量。由此可见，即使处于休眠状态，终端设备既可以发送用于上行定位的SRS(如非周期性SRS)，也可以对用于下行定位的PRS进行测量。由此可见，按照当前协议，DRX模式与上下行定位是相互独立设计的。
唤醒信号
为了终端设备的进一步节能，某些通信系统(如NR Rel-16)引入了基于唤醒信号(或称节能唤醒信号)的唤醒机制。唤醒信号能够与DRX机制结合使用。例如，终端设备可以在DRX on duration之前接收唤醒信号。如果终端设备在一个DRX周期有数据传输，则唤醒信号可以唤醒终端设备，使得终端设备在DRX on duration期间检测PDCCH。如果终端设备在一个DRX周期没有数据传输，则唤醒信号可以不唤醒终端设备。在这种情况下，终端设备可以不启动DRX持续时间定时器，从而不需要进行PDCCH的检测。由此可见，唤醒信号的引入使得终端设备可以省略某个或某些DRX on duration期间的PDCCH检测，从而实现进一步节能。需要说明的是，在本申请实施例中，如果通信系统支持唤醒机制，则术语“唤醒状态”和“激活状态”，以及术语“唤醒时间”和“激活时间”根据特定上下文可以被互换地使用。
结合前文内容可知，当终端设备未处于激活状态时，当前协议规定该终端设备不允许发送周期性SRS和半持续SRS。但是，终端设备的激活时间是难以预知的。例如，基站通过RRC或MAC CE将DRX配置信息发送至终端设备之后，终端设备需要结合该DRX配置信息以及实际的来包情况，确定进入激活时间或结束激活时间。也就是说，单纯根据DRX配置只能推断终端设备可能的激活时间，而实际来包情况通常难以提前获知。除了实际来包情况之外，激活时间还与许多其他参数有关(具体可以参见“DRX模式”一节列出的多种情况1至情况4)，这进一步增加了激活时间的不确定性。此外，在支持唤醒机制的通信系统中，终端设备的激活时间还与唤醒信号有关。例如，如果终端设备接收到唤醒信号，则该唤醒信号可以指示终端设备启动或不启动DRX持续时间定时器，如果唤醒信号指示终端设备不启动DRX持续时间定时器，则即使DRX持续时间定时器配置的时间也不属于激活时间。
激活时间的不可预知性会导致周期性SRS和/或半持续SRS的传输时间具有随机性，从而增加通信过程的不确定性。
除了上述问题之外，目前协议还存在邻区测量失真的问题。具体而言，按照目前协议，邻区无法获知终端设备什么时候处于休眠状态，也就无法获知周期性SRS和/或半持续SRS的有效测量时间。在这种情况下，即使终端设备并未发送某个周期性SRS或半持续SRS，邻区仍然会继续对该SRS进行测量，从而导致邻区定位测量失真。邻区将测量结果上报至核心网的定位设备之后，定位设备会将多个小区的测量结果联合进行位置解算，从而得到终端设备的位置估计。但是，由于邻区上报的测量结果不准确，这会严重降低终端设备的位置估计的准确性。
为了解决上述问题中的一个或多个，下面对本申请实施例进行详细描述。
图4是本申请一个实施例提供的无线通信的方法的流程示意图。图4的方法可以由前文提到的终端设备、基站和核心网中的定位设备中的任一设备执行。以图4的方法由基站执行为例，该基站可以是服务小区所属的基站，也可以是邻区所属的基站。换句话说，图4的方法可以由服务小区执行，也可以由邻区执行。
参见图4，在步骤S410，确定第一时间窗。该第一时间窗为SRS的传输时间窗(或传输时段)。
在一些实施例中，该SRS可以指用于定位的SRS。
在一些实施例中，该SRS可以指周期性SRS和/或半持续SRS。作为示例，该SRS可以指用于定位的周期性SRS和/或半持续SRS。
在一些实施例中，该第一时间窗可以由协议预配置(或称协议预定义)或由基站配置。
在一些实施例中，第一时间窗可以基于DRX持续时间定时器确定。或者说，第一时间窗可以与DRX持续时间定时器具有关联关系(如与DRX持续时间定时器的运行时间具有关联关系)。作为示例，第一时间窗的参数(如第一时间窗的起点和/或长度)可以基于DRX持续时间定时器的参数(如DRX持续时间定时器的起点(或称运行开始时间)和/或运行时长)确定。由于DRX持续时间定时器运行开始时间是事先通过高层信令配置的，所以在系统不配置唤醒信号时，DRX持续时间定时器运行开始时间不是动态变化的，是可以事先预知并通知给邻区或核心网的定位设备的，并且在DRX周期中，DRX持续时间定时器运行的时间，终端设备一定会醒来，也就是根据本申请实施例，定位测量被设置在终端设备一定会醒来时间相关的时间段。测量时间配置在非动态、会激活的区间，这样做的好处是可预先通知邻区或定位设备，使得邻区或定位设备可以在激活时间进行测量，节约功耗。
以步骤S410由终端设备或服务小区执行为例，则步骤S410可以替换为“根据DRX持续时间定时器确定第一时间窗”。以步骤S410由核心网中的定位设备执行为例，则步骤S410可以替换为“根据终端设备或服务小区发送的通知消息确定第一时间窗”。例如，终端设备或服务小区在根据DRX持续时间定时器确定第一时间窗之后，可以以通知消息 的形式将该第一时间窗传输至定位设备。以步骤S410由邻区执行为例，则邻区可以根据定位设备或服务小区的通知消息确定第一时间窗。例如，在服务小区根据DRX持续时间定时器确定第一时间窗之后，可以以通知消息的形式将该第一时间窗传输至邻区。在得到第一时间窗之后，邻区可以根据第一时间窗对SRS进行邻区测量，并将测量结果上报至定位设备。
在一些实施例中，第一时间窗可以位于DRX持续时间定时器对应的时间内。
在一些实施例中，第一时间窗的起点可以与DRX持续时间定时器的起点相同。
在一些实施例中，该第一时间窗的长度可以是静态值。所谓第一时间窗的长度为静态值，指的是第一时间窗的长度可以仅基于高层信令确定(如仅通过高层信令推算得到)，而不随数据(如PDSCH)调度情况动态变化。
在一些实施例中，第一时间窗可以在没有唤醒信号的情况下使用。例如，如果没有唤醒信号，则可以执行步骤S410；如果有唤醒信号，则可以不执行步骤S410。这里提到的“有唤醒信号”可以指系统配置了“唤醒信号”；“没有唤醒信号”可以指系统未配置“唤醒信号”。如果系统配置了“唤醒信号”，则基站会向终端设备发送唤醒信号，以指示终端设备是否需要唤醒以启动DRX持续时间定时器。相应地，如果系统未配置“唤醒信号”，则基站不会向终端设备发送唤醒信号，此时，DRX持续时间定时器通常会按照DRX周期启动。
在一些实施例中，第一时间窗可以在有唤醒信号的情况下使用。第一时间窗在有唤醒信号的情况下使用时，SRS的传输可以忽略唤醒信号(或者，SRS的传输可以与唤醒信号无关)。所谓“SRS的传输忽略唤醒信号”，例如可以指：通过协议预配置或高层信令配置的方式，指示终端设备在DRX持续时间定时器配置的时间仍传输周期性SRS和/或半持续SRS(从而进行定位测量)；或者，通过协议预配置或高层信令配置的方式，指示终端设备在DRX持续时间定时器配置的时间不传输周期性SRS和/或半持续SRS(从而不进行定位测量)。
在一些实施例中，SRS的传输是否忽略唤醒信号可以通过服务小区发送的指示信息确定。该指示信息可用于指示SRS(如用于定位的周期性SRS和/或半持续SRS)的传输是否忽略唤醒信号。该指示信息例如可以是高层信令。
综上，在没有唤醒信号的情况下，DRX持续时间定时器的起点(或运行开始时间)是事先通过高层信令配置的。因此，在没有唤醒信号的情况下，DRX持续时间定时器的起点不是动态变化的，而是可以事先预知并通知给邻区或定位设备的。换句话说，在没有唤醒信号的情况下，DRX持续时间定时器的运行时间通常是可以预知的，而在这段时间内终端设备是一定会醒来的。本申请实施例利用这一点，将SRS的传输时间窗(即前文提到的第一时间窗)设置在与DRX持续时间定时器对应的时间的相关时段内，从而使得SRS的传输时间窗也具有了确定性。例如，可以将第一时间窗设置在DRX持续时间定时器的运行时间内，这样做的好处是可以将该第一时间窗预先通知邻区或定位设备，使得邻区和定位设备可以在终端设备的激活时间内进行定位测量，从而节约功耗。
图5是本申请另一实施例提供的无线通信的方法的流程示意图。图5的方法是站在终端设备和服务小区交互的角度描述的。
参见图5，在步骤S510，服务小区向终端设备发送唤醒信号。在步骤S520，终端设备传输SRS，且SRS的传输忽略唤醒信号(或者，SRS的传输与唤醒信号无关)。
在一些实施例中，该SRS可以指用于定位的SRS。
在一些实施例中，该SRS可以指周期性SRS和/或半持续SRS。作为示例，该SRS可以指用于定位的周期性SRS和/或半持续SRS。
根据前文中的“唤醒信号”一节的描述可知，当系统配置了唤醒信号时，根据唤醒信号的指示，在DRX持续时间定时器配置的时间内，DRX持续时间定时器可能并不运行。因此，终端设备在DRX持续时间定时器配置的时间内可能并不会醒来进入激活时间。按 照目前标准，如果终端设备不醒来进入激活时间，则终端设备不会在DRX持续时间定时器配置的时间传输用于定位的周期性SRS和/或半持续SRS。由此可见，唤醒信号的引入会导致周期性SRS和/或半持续SRS的传输时间不确定。
为了避免唤醒信号对周期性SRS和/或半持续SRS的传输时间的影响，本申请实施例提出终端设备在传输周期性SRS和/或半持续SRS时，忽略唤醒信号。所谓“SRS的传输忽略唤醒信号”，例如可以指：通过协议预配置或高层信令配置的方式，指示终端设备在DRX持续时间定时器配置的时间仍传输周期性SRS和/或半持续SRS(从而进行定位测量)；或者，通过协议预配置或高层信令配置的方式，指示终端设备在DRX持续时间定时器配置的时间不传输周期性SRS和/或半持续SRS(从而不进行定位测量)。
在SRS的传输时间确定下来之后，无论终端设备处于激活状态还是未激活状态，该终端设备均可以按照设定的该传输时间传输SRS。或者，在一些实施例中，终端设备也可以仅在SRS的传输时间中的含有激活时间的传输时间内发送SRS。
在一些实施例中，在步骤S510之前，还可以包括步骤S505，即终端设备接收服务小区发送的指示信息。该指示信息可用于指示SRS(如用于定位的周期性SRS和/或半持续SRS)的传输是否忽略唤醒信号。
在一些实施例中，服务小区或定位设备可以将SRS的传输时间通知邻区。在收到该SRS的传输时间之后，邻区可以基于该SRS的传输时间对该SRS进行邻区测量，并将测量结果上报至定位设备，以便定位设备对终端设备的位置进行解算。
图6是本申请又一实施例提供的无线通信的方法的流程示意图。图6的方法是站在定位设备、服务小区(或服务小区对应的基站)、邻区(或邻区对应的基站)以及终端设备交互的角度进行描述的。终端设备、基站和定位设备的相关描述可以参见前文。以NR系统为例，基站可以为gNB，该定位设备可以为LMF。服务小区对应的基站和邻区对应的基站可以是同一基站，也可以不同基站。
参见图6，在步骤S620，服务小区向定位设备发送第一信息。可替换地，在一些实施例中，该第一信息也可以由终端设备向定位设备发送。以第一信息由服务小区发送为例，由于服务小区一般会向定位设备发送终端设备的SRS的配置信息(该SRS的配置用于定位设备从中选择部分SRS，作为上行定位的SRS)。因此，在一些实施例中，该第一信息可以与该SRS的配置信息一起发送至定位设备。
该第一信息可以指示终端设备的实际激活时间。前文提到，终端设备的激活时间受到很多因素的影响，具有一定的随机性。所谓“实际激活时间”，指的是考虑了这些因素之后，终端设备实际上会处于激活状态的时间(或真正处于激活状态的时间)。终端设备或服务小区通常能够准确获知该实际激活时间，因此，可以由终端设备或服务小区将该实际激活时间发送至定位设备，从而帮助定位设备进行定位测量。
本申请实施例对第一信息的内容不作具体限定，只要基于该第一信息可以直接获得或推算出终端设备的实际激活时间即可。作为一个示例，第一信息可以直接指示终端设备的实际激活时间。作为另一示例，第一信息可以包含影响终端设备的实际激活时间的各个参数，使得定位设备根据这些参数可以推算出该实际激活时间。
进一步地，在一些实施例中，在定位设备得到第一信息之后，该定位设备可以根据第一信息确定第一测量结果。这里提到的第一测量结果指的是邻区对终端设备在实际激活时间内传输的SRS进行测量得到的测量结果。
第一测量结果的确定方式可以有多种，下文给出两种可能的实现方式。
作为一种可能的实现方式，参见图6，定位设备向邻区发送第一信息(步骤S630)。例如，定位设备可以通过NR定位协议a(NR positioning protocol a，NRPPa)信令将第一信息发送至邻区。由于定位设备通常会向邻区发送该终端设备的SRS的配置信息，以便邻区进行邻区测量。因此，在一些实施例中，定位设备可以将该第一信息与该SRS的配置信息一起(或作为SRS的配置信息的一部分)，发送至邻区。在获取到第一信息之后，邻区 可以根据第一信息进行邻区测量，得到上述第一测量结果(步骤S640)。然后，邻区可以将第一测量结果发送至定位设备(参见步骤S650)。
作为另一种可能的实现方式，定位设备也可以接收邻区对SRS进行测量得到的第二测量结果。该第二测量结果可以包括有效测量结果(如前文提到的第一测量结果)和无效测量结果(如第二测量结果中的测量时间位于DRX的休眠时间的测量结果)。进一步地，该第二测量结果可以包括SRS的测量时间。定位设备获取到第二测量结果之后，可以根据该第二测量结果中包括的SRS的测量时间以及之前得到的第一信息，从第二测量结果中选取第一测量结果。例如，定位设备可以根据SRS的测量时间对第二测量结果进行筛选，保留第二测量结果中的测量时间位于第一信息指示的实际激活时间内的测量结果。
重新参见图6，在一些实施例中，图6的方法还可以包括步骤S660，即定位设备根据第一测量结果确定终端设备的位置信息。由于第一测量结果排除了邻区测量结果中的部分或全部无效测量结果(位于DRX休眠时间的测量结果)，从而可以使得终端设备的位置信息的计算更准确。
在一些实施例中，在步骤S620之前，图6的方法还可以包括步骤S610：终端设备与定位设备交互终端设备的能力信息。该能力信息的交互可以通过LTE定位协议(LTE positioning protocol，LPP)信令实现。例如，定位设备可以先向终端设备发送询问消息，以询问终端设备是否具备上行定位能力；终端设备在收到该询问消息之后，可以向定位设备发送该询问消息的响应消息，以通知定位设备自己具备上行定位能力。
