一种通信资源的确定方法及通信装置
相关申请的交叉引用
本申请要求在2021年09月09日提交中国国家知识产权局、申请号为202111057895.9、申请名称为“一种通信资源的确定方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信资源的确定方法及通信装置。
背景技术
NR(new radio，新空口)系统中，接入网设备可以将物理下行控制信道(physical downlink control channel，PDCCH)在频域上占据的频段，和在时域上占用的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号数等信息封装在控制资源集(control resource set，CORESET)中；将物理下行控制信道的起始符号编号以及物理下行控制信道监测周期等信息封装在搜索空间(search space，SS)中，通过无线资源控制(radio resource control，RRC)信令向终端设备发送CORESET和SS。终端设备可以根据接入网设备发送的CORESET和SS确定资源，并在该确定的资源上检测物理下行控制信道。
在接入网设备确定小区负载变化时，接入网设备可根据小区负载的变化情况改变CORESET和SS，然后基于RRC信令的重配置过程向终端设备配置该改变之后CORESET和SS，从而终端设备可根据该改变之后CORESET和SS确定改变之后的物理下行控制信道的资源，并在该资源上检测物理下行控制信道。
但是基于RRC信令的重配置过程可能需要经过较长时间，比如经过几个或者几十个发射时间间隔(transmission time interval，TTI)之后，接入网设备才能成功将改变之后CORESET和SS配置给终端设备。如此，接入网设备不能基于小区负载的变化情况，及时地向终端设备重新配置CORESET和SS，导致接入网设备与终端设备之间的用于传输物理下行控制信道的资源不能较好的适用于小区负载。
发明内容
本申请提供一种通信资源的确定方法及通信装置，在小区负载发生变化时，有助于实现接入网设备与终端设备之间的用于传输物理下行控制信道的资源可较好的适用于小区负载。
第一方面，本申请提供一种通信资源的确定方法，该通信资源的确定方法可以由终端设备或者终端设备中模块(比如芯片)执行。如下以该方法由终端设备执行举例说明。
在一种可能的实现方式中，该通信资源的确定方法包括：终端设备接收来自接入网设备的第一指示信息，第一指示信息与终端设备所属的小区的负载信息相关联；终端设备根据第一指示信息和第一信息，确定用于终端设备检测物理下行控制信道的第一资源；第一信息中包括多个资源信息，第一指示信息对应于多个资源信息中的第一资源信息，第一资 源信息用于指示第一资源。在一种可能的实现方式中，第一信息还包括多个指示信息，多个指示信息和多个资源信息分别对应，多个指示信息中包含第一指示信息。
上述技术方案中，接入网设备可以根据小区的负载信息确定第一指示信息，并将该第一指示信息发送给终端设备，相应的，终端设备可根据第一指示信息和第一信息确定出第一资源，在第一资源上检测物理下行控制信道。在小区的负载信息发生变化时，接入网设备无需向终端设备重配置物理下行控制信道的配置信息，有助于提升接入网设备向终端设备指示用于传输物理下行控制信道的资源的速度。且终端设备确定出的用于传输物理下行控制信道的资源可较好的适用于终端设备所属的小区的负载信息。
在一种可能的实现方式中，第一信息中不同资源信息指示的用于终端设备检测物理下行控制信道的资源大小不同。在一种可能的实现方式中，第一信息中不同资源信息指示的用于终端设备检测物理下行控制信道的资源中包括的符号数和带宽中至少有一项不同。

上述技术方案中，接入网设备给终端设备配置多个不同的部分带宽，且每个部分带宽可独立配置有各自对应的资源信息，即每个部分带宽可以对应有各自的符号数和/或频域带宽。接入网设备可以通过调度终端设备切换工作带宽的方式，来为终端设备指示对应的资源信息。在小区负载发生变化时，接入网设备可快速高效的为终端设备指示与变化之后的小区负载相对应的第一部分带宽信息，有助于实现接入网设备与终端设备之间的用于传输物理下行控制信道的资源可较好的适用于小区负载。进一步的，第一部分带宽信息可以是接入网设备通过下行控制信息(downlink control information，DCI)向终端设备发送的，第一部分带宽信息可实现TTI粒度的配置。
在一种可能的实现方式中，多个资源信息中还包括第二资源信息，第二资源信息用于指示第二资源，第二资源中包括第一资源。在一种可能的实现方式中，第二资源中除第一资源以外的其他资源可用于终端设备接收物理下行共享信道，物理下行共享信道的位置可以是由第一资源中的物理下行控制信道中的速率匹配图样信息来指示。
上述技术方案中，接入网设备可以为终端设备设置多个速率匹配图样信息对应的速率匹配图样，即每个速率匹配图样可用于指示不同的物理下行共享信道的位置。接入网设备可以通过在物理下行控制信道中携带速率匹配图样信息的方式，为终端设备指示物理下行共享信道的位置，从而有助于提高资源的利用率。
在一种可能的实现方式中，该通信资源的确定方法还包括：终端设备通过RRC信令接收来自接入网设备的第一信息。
第二方面，本申请提供一种通信资源的确定方法，该通信资源的确定方法可以由接入网设备或者接入网设备中模块(比如芯片)执行。如下以该方法由接入网设备执行举例说明。

在一种可能的实现方式中，该通信资源的确定方法还包括：接入网设备根据预设策略，从小区所服务的终端设备中选择终端设备。在一种可能的实现方式中，预设策略可以是随机选择策略，或者是根据信号强度选择。在接入网设备根据信号强度从小区所服务的终端设备中选择终端设备的情况中，接入网设备可以确定该小区所服务的多个终端设备中各终端设备的信号强度，并选择信号强度符合预设条件的终端设备。
在一种可能的实现方式中，该通信资源的确定方法还包括：接入网设备通过RRC信令向终端设备发送第一信息。

上述技术方案中，接入网设备可以根据小区的负载信息确定第一资源信息，该第一资源信息指示的第一资源可用于接入网设备向终端设备发送物理下行控制信道。终端设备可确定多个资源信息分别指示的资源，并在多个资源信息分别指示的资源上检测是否接收到物理下行控制信道，即终端设备通过全量检测的方式确定是否接收到物理下行控制信道。通过该方式，接入网设备与终端设备之间的用于传输物理下行控制信道的资源可较好的适 用于终端设备所属的小区的负载信息。
在一种可能的实现方式中，多个资源信息中不同资源信息指示的用于终端设备检测物理下行控制信道的资源的大小不同。在一种可能的实现方式中，多个资源信息中不同资源信息指示的用于终端设备检测物理下行控制信道的资源中包括的符号数和带宽中至少有一项不同。
上述技术方案中，接入网设备可预先向终端设备指示多个资源信息，该多个资源信息可指示不同大小的资源，从而在终端设备所属小区的负载信息不同的情况下，接入网设备可确定出与小区的负载信息相对应大小(或容量)的传输资源，而终端设备可通过全量检测，检测到在该传输资源上传输的物理下行控制信道。
在一种可能的实现方式中，多个资源信息中还包括第二资源信息，第二资源信息用于指示第二资源，第二资源中包括第一资源。在一种可能的实现方式中，第二资源中除第一资源以外的其他资源可用于终端设备接收物理下行共享信道。物理下行共享信道的位置可以是由第一资源中的物理下行控制信道中的速率匹配图样信息来指示。上述技术方案有助于提高资源的利用率。

具体实施方式
下面将结合附图，对本申请进行详细描述。
如图1所示，为本申请所适用的一种通信系统的架构示意图，包括终端设备和接入网设备。该终端设备通过无线接口与接入网设备通信。
终端设备(terminal device)，是一种具有无线收发功能的设备，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(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、用户设备(user equipment，UE)等。
接入网设备，是一种为终端设备提供无线通信功能的设备，接入网设备包括但不限于：下一代基站(g nodeB，gNB)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)等。
为了兼容不同的业务、接入技术、带宽、制式等需求，NR系统中可支持物理下行控制信道资源的灵活配置，但取消了物理控制格式指示信道(physical control format indicator channel，PCFICH)，即接入网设备无法以显示指示的方式向终端设备指示接入网设备和终端设备之间的用于传输物理下行控制信道的资源。
本申请中，用于传输物理下行控制信道的资源还可以称为是PDCCH资源或下行控制资源，接入网设备与终端设备之间传输的PDCCH还可称为是DCI。PDCCH可用于调度物理下行共享信道(physical downlink shared channel，PDSCH)，接入网设备与终端设备之间传输的PDSCH还可称为是下行数据。本申请实施例中将物理下行控制信道称为是PDCCH，物理下行共享信道称为是PDSCH，终端设备称为是UE。可以理解的是，PDSCH、PDCCH和UE只是作为物理下行共享信道、物理下行控制信道和终端设备的一种举例，在不同的系统和不同的场景中，物理下行共享信道、物理下行控制信道和终端设备均可能有不同的名称，本申请的实施例对此并不做限定。
在NR系统中，接入网设备可通过CORESET和SS，向UE指示用于该UE检测PDCCH的资源(如下可称为PDCCH资源)。其中，UE检测PDCCH可理解为UE在PDCCH资源进行检测，并确定是否可以检测到PDCCH。若接入网设备在该PDCCH资源上向UE发送PDCCH，则UE在该PDCCH资源上可以检测到PDCCH；若接入网设备在该PDCCH资源上未向UE发送PDCCH，则UE在该PDCCH资源上不能检测到PDCCH。
具体的，接入网设备将PDCCH在频域上占据的频段和在时域上占用的符号数等信息封装在CORESET中；将PDCCH的起始符号的编号以及PDCCH监测周期等信息封装在SS中。其中，在时域上的符号可以是OFDM符号，也可以是离散傅里叶变换扩频OFDM符号。如果没有特别说明，本申请实施例中的符号均指在时域上的符号。
接入网设备可以在UE随机接入的时候，向UE发送配置信息，该配置信息可包括CORESET和SS。UE可根据配置信息中包括的CORESET和SS，确定UE检测PDCCH所需的信息，其中UE检测PDCCH所需的信息可包括检测PDCCH对应的符号数、频域位置、DCI类型、聚合级别及对应的检测次数等。
如图2示例性示出的UE确定PDCCH资源的示意图中，左边部分可理解为UE接收到的来自于网络的配置信息，配置信息中包括的CORESET和SS，UE可根据SS确定UE检测PDCCH对应的时隙(slot)、DCI类型、聚合级别等，UE还可根据CORESET确定图样(pattern)，其中，可以将UE检测PDCCH对应的slot称为是检测slot，将UE根据CORESET确定出的图样称为检测资源图样。右边部分可理解为UE从多个slot中确定出检测slot，该检测slot为slot M，UE可以进一步根据检测资源图样在slot M中确定出检测PDCCH对应的时域位置和频域位置(可参见图2示出的slot M中的阴影部分，其中纵坐标指示UE检测PDCCH对应的频域位置，横坐标指示UE检测PDCCH对应的时域位置)。
如图3为本申请示例性提供的一种接入网设备配置PDCCH资源的流程示意图：
步骤301，UE与接入网设备建立无线链路连接。
步骤302，接入网设备根据小区的负载信息，生成配置信息。
本申请中，接入网设备可对应于多个小区(cell)，每个小区中可以有多个UE接入，或者说每个小区可服务有多个UE，或者说每个小区中可以有多个UE。而对于UE来说，其接入的小区即为该UE的服务小区(service cell)。接入网设备可针对于每个小区，根据该小区的负载情况，比如该小区中UE的接入数量、该小区中UE请求的资源量、小区内接入网设备给UE分配PDCCH资源的成功率等因素中的至少一项，确定该小区的负载信息，该负载信息用于指示该小区的负载情况。
接入网设备可根据小区的负载信息，确定向小区内UE传输PDCCH所需的资源大小。结合小区中UE的接入数量举例说明，小区的负载越大，接入至小区的UE的数量则越多，而接入网设备需要为接入至小区中的多个UE分别发送PDCCH，从而接入网设备向小区内UE传输PDCCH所需资源则越多，即需要较大的PDCCH资源；同样的，小区的负载越小，接入网设备向小区内UE传输PDCCH所需资源则越少，即需要较小的PDCCH资源。示例性的，资源大小又可称为资源容量，可通过时域资源大小和频域资源大小来衡量，其中时域资源大小可以是一个slot中包括的符号数，频域资源大小可以是资源带宽或者在频域上包括的资源块(resource block，RB)数。
进一步的，接入网设备可根据向小区内UE传输PDCCH所需的资源大小，生成CORESET和SS，该CORESET和SS作为该配置信息。
步骤303，接入网设备向UE发送该配置信息；该配置信息可由接入网设备通过RRC信令向UE发送。
步骤304，UE根据该配置信息，确定PDCCH资源。一个可能的具体实现中，UE可根据配置信息中包括的SS确定UE检测slot、DCI类型、聚合级别等，以及根据配置信息中包括的CORESET确定出UE检测slot上的检测资源图样，进而根据检测资源图样从检测slot中确定出用于检测PDCCH的资源(即PDCCH资源)。
步骤305，UE和接入网设备在PDCCH资源上传输PDCCH。
对于UE来说，UE可在PDCCH资源上检测PDCCH，若接入网设备在该PDCCH资源上向UE发送PDCCH，则UE在该PDCCH资源上可以检测到PDCCH；若接入网设备在该PDCCH资源上未向UE发送PDCCH，则UE在该PDCCH资源上不能检测到PDCCH。
在一种可能的实现方式中，PDCCH用于调度PDSCH，UE可以根据PDCCH中指示的PDSCH的资源位置，进一步接收来自接入网设备的PDSCH。
接入网设备还可以根据小区的负载信息，调整向小区内UE传输PDCCH所需的资源 大小。当接入网设备确定小区负载增大时，可以增大PDCCH资源，当接入网设备确定小区负载减小时，可以减少PDCCH资源。通过该方式，可有助于实现接入网设备灵活调度PDCCH资源，有助于提高资源的利用率。
由于接入网设备需要通过RRC信令向UE发送配置信息，而基于RRC信令的重配置过程较慢，可能需要经过较长时间比如几个或者几十个TTI，才能向UE重新发送配置信息，导致接入网设备与UE之间用于传输PDCCH的资源大小不能及时的适用于小区负载。
如此，本申请提供一种通信资源的确定方法，该方法可用于在小区负载发生变化时，接入网设备与UE之间的用于传输PDCCH的资源可较好的适用于小区负载。该方法可以由图1示例性示出的终端设备(即UE)和接入网设备执行。
在一种可能的实现方式中，接入网设备可预先向UE发送第一信息，该第一信息中可包括多个指示信息和多个指示信息对应的资源信息。指示信息对应的资源信息可用于指示PDCCH资源(或者说，可用于指示PDCCH资源所在的位置)。
一种具体实现中，该资源信息可用于指示PDCCH的时域资源和频域资源。其中时域资源可以是PDCCH在slot中可占用的一个或多个符号，示例性的，在NR系统中一个slot中可包括14个符号，PDCCH可占用该slot中的1个、2个或3个符号。频域资源可以是小区带宽，其中小区带宽可理解为UE所在的小区占用的带宽，该小区带宽比如可以是20MHz、60MHz等。示例性的，该资源信息可以包括CORESET和SS。
在一种可能的方式中，指示信息可以是部分带宽(bandwidth part，BWP)信息，即第一信息中可包括多个BWP信息和多个BWP信息分别对应的资源信息。又或者，指示信息可以是检测资源图样信息，即第一信息中可包括多个检测资源图样信息和多个检测资源图样信息分别对应的资源信息。具体实现可参见下述图4至图8相关实施例中的描述。
本申请中，多个资源信息分别指示的PDCCH资源的资源大小可以相同，也可以不同。可以通过PDCCH资源在时域上占用的符号数，以及在频域上占用的带宽来衡量PDCCH资源的资源大小。多个资源信息分别指示的PDCCH资源中包括的符号数可以相同，也可以不同，比如多个资源信息中，某一个资源信息指示的PDCCH资源中包括的符号数为1，而另一个资源信息指示的PDCCH资源中包括的符号数为2，即该两个资源信息指示的PDCCH资源中包括的符号数不同。多个资源信息分别指示的PDCCH资源中包括的带宽可以相同，也可以不同，比如多个资源信息中，某一个资源信息指示PDCCH资源中包括的带宽为20MHz，而另一个资源信息指示PDCCH资源中包括的带宽为20MHz，即该两个资源信息指示的PDCCH资源中包括的带宽相同。
在一种可能的方式中，接入网设备可以将该第一信息通过高层信令配置给UE，高层信令比如是RRC信令。示例性的，接入网设备可向UE发送RRC重配置消息，该RRC重配置消息中包括第一信息。
如下结合图4示出的一种通信资源的确定方法的流程示意图解释说明。该流程中：
步骤401，接入网设备根据小区的负载信息和第一信息，确定第一指示信息。
接入网设备可以监测小区的负载情况，然后根据小区的负载情况确定小区的负载信息。示例性的，接入网设备可以在每个TTI中监测小区的负载情况，然后基于多个TTI中小区负载情况来确定小区的负载信息。其中，小区的负载情况比如是小区内处于RRC连接态的UE的数量，或者接入网设备给小区内UE分配PDCCH资源的成功率等。
在一种可能的方式中，小区的负载信息可以是小区负载等级，小区负载等级比如可包括轻负载、中负载和重负载。举个例子，当小区内处于RRC连接态的UE的数量小于500时，小区负载等级为低负载；当小区内处于RRC连接态的UE的数量大于500且小于1000时，小区负载等级为中负载；当小区内处于RRC连接态的UE的数量大于1000时，小区负载等级为重负载。
其中，第一信息中可包括多个资源信息，第一指示信息可对应于该多个资源信息中的第一资源信息，第一资源信息可用于指示第一资源。
该第一信息中还可包括多个指示信息，该多个指示信息与多个资源信息对应，示例性的，多个指示信息与多个资源信息可以为一一对应关系。
进一步的，一个示例中，第一指示信息是该多个指示信息中的一个，第一信息中第一指示信息对应的资源信息即第一资源信息。比如第一信息中包括指示信息1、指示信息2和指示信息3，以及指示信息1、指示信息2和指示信息3分别对应的资源信息1、资源信息2和资源信息3，第一指示信息比如是指示信息1，则第一资源信息是资源信息1。
又一个示例中，第一指示信息对应于该多个指示信息中的一个(可以理解，第一指示信息不包含于该多个指示信息中，第一指示信息所对应的指示信息包含于该多个指示信息中)，该第一指示信息所对应的指示信息在第一信息中可对应于第一资源信息。比如第一信息中包括指示信息1、指示信息2和指示信息3，以及指示信息1、指示信息2和指示信息3分别对应的资源信息1、资源信息2和资源信息3，第一指示信息比如是指示信息A，该指示信息A对应于指示信息1，第一信息中指示信息1对应于资源信息1，也可以理解，指示信息A对应的第一资源信息为资源信息1。
如下为方便描述，可以以第一指示信息是第一信息中的一个指示信息为例，解释说明接入网设备根据小区的负载信息和第一信息，确定第一指示信息的实现方式。
接入网设备可以根据小区的负载信息从多个指示信息中确定第一指示信息，该第一指示信息对应的资源信息即为第一资源信息，第一资源信息指示的PDCCH资源大小可以与小区的负载信息相匹配。可以理解，接入网设备可根据小区的负载信息，从第一信息的多个指示信息中确定出对应的PDCCH资源大小符合小区的负载信息的第一指示信息。
第一指示信息与小区的负载信息相关联，其中相关联又可认为是相对应或者具有对应关系。示例性的，小区的负载信息为小区负载等级。小区负载等级分别为轻负载、中负载和中负载时，可分别对应于第一信息中的不同指示信息，相应的，接入网设备可以根据小区负载等级确定第一信息中与小区负载等级相关联的第一指示信息；相关联也可以认为是，第一指示信息需要根据小区的负载信息来确定。
在一种可能的方式中，第一信息中可包括三个指示信息和三个指示信息分别对应的资源信息，其中该三个指示信息分别与轻负载、中负载和重负载对应。进一步的，轻负载对应的PDCCH资源可小于中负载对应的PDCCH资源，中负载对应的PDCCH资源可小于重负载对应的PDCCH资源。以符号数(其中资源带宽相同)为例，第一信息中可包括与轻负载、中负载和重负载分别对应的指示信息1、指示信息2和指示信息3。其中，该指示信息1对应的资源信息1指示PDCCH资源在时域上包括1个符号；该指示信息2对应的资源信息2指示PDCCH资源在时域上包括2个符号；该指示信息3对应的资源信息3指示PDCCH资源在时域上包括3个符号。
在一种可能的实现方式中，接入网设备可以在UE接入时，确定小区的负载信息，然 后根据小区的负载信息确定第一指示信息。在又一种可能的实现方式中，接入网设备可在小区的负载信息发生变化时，根据发生变化之后的小区的负载信息，确定第一指示信息。
此外，在第一指示信息对应于该多个指示信息中的一个的示例中，可以理解，接入网设备根据小区的负载信息和第一信息，从第一信息中确定与小区负载等级相关联的第三指示信息，该第三指示信息对应于第一指示信息。具体实现方式均可参见上述接入网设备确定第一指示信息的方式，不再赘述。
步骤402，接入网设备向UE发送第一指示信息。
在指示信息是BWP信息的情况下，第一信息中可包括多个BWP信息和多个BWP信息分别对应的资源信息，第一指示信息可以是第一BWP信息，第一资源信息可以是第一信息中第一BWP信息对应的资源信息。需要补充的是，该第一BWP信息不仅可指示UE确定第一资源信息，还可指示或被UE用于根据该第一BWP信息进行工作BWP的切换。
在指示信息是检测资源图样信息的情况下，第一信息中可包括多个检测资源图样信息和多个检测资源图样信息分别对应的资源信息，第一指示信息可以是第一检测资源图样信息，UE可根据该第一检测资源图样信息从第一信息中确定第一检测资源图样信息对应的第一资源信息，然后根据该第一资源信息确定出第一资源。
接入网设备可向UE发送DCI，该DCI中携带有第一指示信息。
步骤403，UE根据第一指示信息和第一信息，确定第一资源。
UE可根据第一指示信息，从第一信息中确定第一资源信息，然后根据第一资源信息，确定第一资源，该第一资源为UE检测PDCCH的资源。
需要补充的是，接入网设备可以指示该小区中的所有UE变更用于检测PDCCH的资源。或者接入网设备还可以指示该小区中的部分UE变更用于检测PDCCH的资源，可将该小区中的部分UE称为是目标UE。
可能方式1：接入网设备可以向小区中的所有UE发送该第一指示信息。相应的，小区中的所有UE可根据该第一指示信息，确定第一资源。
在可能方式1中，可设置第一信息中两个资源信息指示的PDCCH资源大小不同。示例性的，资源信息2指示的资源的大小，大于资源信息1指示的资源的大小，小区中所有UE基于资源信息1指示的资源来检测PDCCH，当接入网设备确定小区负载增大时，可向小区中所有UE发送用于指示资源信息2的指示信息2，小区中所有UE可根据指示信息2对应的资源信息2，确定用于检测PDCCH的资源。
可能方式2：接入网设备可根据预设策略，从小区UE中选择目标UE，向目标UE发送该第一指示信息。相应的，小区中的目标UE可根据该第一指示信息，确定第一资源。
在可能方式2中，可设置第一信息中两个资源信息指示的PDCCH资源大小相同。示例性的，资源信息1指示的资源与资源信息2指示的资源具有相同大小，小区中所有UE基于资源信息1指示的资源来检测PDCCH，当接入网设备确定小区负载增大时，可从小区UE中选择目标UE，并向目标UE发送用于指示资源信息2的指示信息2，相应的，目标UE接收到指示信息2之后，可根据资源信息2确定用于检测PDCCH的资源。小区中未接收到指示信息2的UE，仍可根据资源信息1确定用于检测PDCCH的资源。
在该可能方式2中，预设策略可以是随机选择策略，比如小区中有1000个UE，接入 网设备可以从该1000个UE中随机选择出500个UE作为目标UE。预设策略还可以是接入网设备根据信号强度选择。示例性的，接入网设备可以确定该小区中各UE的信号强度，并选择信号强度符合预设条件的UE，比如小区中有1000个UE，接入网设备可以确定该1000个UE的信号强度，然后从该1000个UE中选择出信号强度大于预设阈值的UE作为目标UE，或者接入网设备可以根据信号强度将该1000个UE进行由高到低的排序，并从该排序中选择出前500个UE作为目标UE。预设策略还可以是其他策略，本申请不限定。
可选的，步骤404，接入网设备可以在第一资源上向UE发送PDCCH。相应的，UE可在该第一资源上通过检测的方式接收到PDCCH。
需要补充的是，第一信息中还可包括第二指示信息，在第一信息中该第二指示信息对应于第二资源信息，第二资源信息指示的第二资源可以是接入网设备配置的、用于UE传输PDCCH的最大PDCCH资源，可以理解，接入网设备可以在第二资源中的部分资源或全部资源上向UE发送PDCCH，当接入网设备在第二资源的全部资源上向UE发送PDCCH时，该第二资源与第一资源为相同资源；当接入网设备在第二资源的部分资源上向UE发送PDCCH时，该第二资源中包含有第一资源。在后一种情况中，接入网设备不仅可以与UE通过第一资源传输PDCCH，还可在第二资源中除第一资源以外的其他资源上与UE传输PDSCH。示例性的，该PDSCH可以是由第一资源中的PDCCH来调度。
如下以指示信息为BWP信息为例，详细解释说明本申请实施例。
在UE处于RRC空闲态的情况下，接入网设备可通过系统消息配置初始部分带宽(初始BWP，initial BWP)用于UE的初始接入。当UE进入到RRC连接态的情况下，接入网设备可以为UE配置多个专用部分带宽(dedicated BWP)，接入网设备可以通过动态指示来激活UE的dedicated BWP。如图5示例性示出的UE对应的多个BWP的示意图，UE通过initial BWP接入至接入网设备，UE进入RRC连接态，然后接入网设备为UE配置3个dedicated BWP，3个dedicated BWP可分别表示为BWP1、BWP2、BWP3。示例性的，在时间t1，接入网设备为UE激活BWP1，UE可在BWP1上与接入网设备通信。在时间t2，接入网设备为UE激活BWP2，UE可在BWP2上与接入网设备通信。在时间t3，接入网设备为UE激活BWP3，UE可在BWP3上与接入网设备通信。在同一时刻，UE只有一个激活的dedicated BWP。UE当前被激活的dedicated BWP可称为是工作BWP，也可以理解，UE工作在工作BWP上，UE可在工作BWP上与接入网设备通信。
第一信息中可包括多个BWP信息和多个BWP信息对应的资源信息，其中BWP信息指示的BWP可以是initial BWP或者dedicated BWP。
一个示例中，BWP信息对应的资源信息可以是PDCCH资源的配置信息，该PDCCH资源的配置信息中可包括CORESET和SS，UE可以根据该PDCCH资源的配置信息确定PDCCH资源，如下将PDCCH资源的配置信息均简称为是配置信息。
可以理解，第一信息中可包括多个BWP信息和多个BWP信息分别对应的配置信息。示例性的，第一信息中包括的BWP信息和配置信息的对应关系可参见表1所示，其中，BWP信息1与配置信息1相对应，BWP信息2与配置信息2相对应等。该第一信息可以是接入网设备通过一条RRC信令发送给UE的。在该示例中，UE可以在接收到第一BWP信息之后，根据第一BWP信息从第一信息中匹配出配置信息(即第一资源信息，又可称为第一配置信息)，然后根据该第一配置信息确定第一资源。
表1
BWP信息 配置信息
BWP信息1 配置信息1
BWP信息2 配置信息2
BWP信息3 配置信息3
…… ……
又一个示例中，BWP信息对应的资源信息还可以是标识，该标识可用于指示配置信息。可以理解，第一信息中包括第二信息和第三信息，其中第二信息中包括多个BWP信息和多个BWP信息分别对应的标识，第三信息中包括多个标识和多个标识分别指示的配置信息。示例性的，第二信息中包括的BWP信息和标识的对应关系可参见表2所示，第三信息中包括的配置信息和标识的对应关系可参见表3所示。该第二信息和第三信息可承载于相同的RRC信令中，也可承载于不同的RRC信令中。
在该示例中，UE可以在接收到第一BWP信息之后，根据第一BWP信息从第二信息中匹配出目标标识(即第一资源信息)，然后根据该目标标识从第三信息中匹配出配置信息(又可称为第一配置信息)，并根据第一配置信息确定第一资源。
表2

BWP信息1 标识1
BWP信息2 标识2
BWP信息3 标识3
…… ……
表3
标识 配置信息
标识1 配置信息1
标识2 配置信息2
标识3 配置信息3
…… ……
第一信息中还可以包括多个BWP信息与多个BWP信息分别对应的其他信息，该其他信息又可进一步指示配置信息，UE可确定第一BWP信息对应的该其他信息，然后确定该其他信息对应的配置信息，即第一信息主要用于UE根据第一BWP信息确定第一资源，本申请可不限制第一信息中的具体内容。如下为方便描述，均以第一信息中包括多个BWP信息和多个BWP信息分别对应的配置信息为例说明。
在第一信息中，不同配置信息指示的资源大小可以相同或不同。具体的，不同配置信息指示的资源中符号数可以相同或不同，以及不同配置信息指示的资源中资源带宽可以相同或不同。基于不同配置信息指示的资源大小是否相同，如下至少分两种情况说明：
情况1，第一信息中各配置信息可对应于不同大小的资源。
比如表4中多个BWP信息可包括BWP信息1、BWP信息2和BWP信息3，该BWP 信息1、BWP信息2和BWP信息3分别为BWP1、BWP2、BWP3对应的BWP信息，且分别对应于配置信息11、配置信息12和配置信息13。
示例性的，配置信息11对应于1个符号和20MHz，配置信息11可指示PDCCH在时域上占用slot中的第1个符号，以及在频域上占用20MHz；
配置信息12对应于2个符号和20MHz，配置信息12可指示PDCCH在时域上占用slot中的第1个符号和第2个符号，以及在频域上占用20MHz；
配置信息13对应于3个符号和20MHz，配置信息13可指示PDCCH在时域上占用slot中的第1个符号、第2个符号和第3个符号，以及在频域上占用20MHz。
表4
指示信息 配置信息 符号数 资源带宽
BWP信息1 配置信息11 1 20MHz
BWP信息2 配置信息12 2 20MHz
BWP信息3 配置信息13 3 20MHz
可以理解，接入网设备可以为UE配置最大PDCCH资源(即第二资源)，该第二资源可由第二指示信息对应的第二资源信息来指示。其中第二资源信息又可称为第二配置信息。结合表4中例子，第二指示信息为BWP信息3，第二配置信息为配置信息13，该第二资源可由BWP信息3对应的配置信息13来指示，即第二资源在时域上占用slot中的第1个符号、第2个符号和第3个符号，以及在频域上占用20MHz。示例性的，第二资源可包括配置信息12指示的资源，也可包括配置信息11指示的资源。
在小区的负载信息发生变化的情况下，比如小区的负载等级由轻负载变为中负载，再比如小区的负载等级由重负载变为中负载，接入网设备可以根据当前小区的负载信息来确定用于传输PDCCH的资源大小，并将该资源大小对应的指示信息(即第一BWP信息)发送给UE，该第一BWP信息可用于指示UE切换工作BWP。
为方便描述，本申请中可区分第一BWP和第二BWP：UE工作在第二BWP上，然后UE接收到来自接入网设备的第一BWP信息，UE根据该第一BWP信息将工作BWP切换为第一BWP，其中第一BWP是与第一BWP信息相对应的BWP。可以理解，将UE接收第一BWP信息之前的工作BWP称为是第二BWP，将UE接收第一BWP信息之后的工作BWP称为是第一BWP。
一个具体实现方式中，小区的负载增大时，接入网设备可以向UE发送第一BWP信息。UE在接收到该第一BWP信息之后，从当前工作的第二BWP切换至第一BWP，UE还可根据第一BWP信息和第一信息，确定第一信息中与第一BWP信息相对应的第一配置信息，UE根据该第一配置信息确定PDCCH资源，并在该PDCCH资源上检测PDCCH。上述实施例中，第一BWP对应的PDCCH资源大于第二BWP对应的PDCCH资源，有助于接入网设备使用更多的资源来传输PDCCH。
结合表4举例，小区的负载等级为轻负载，比如小区内处于RRC连接态的UE有400个，接入网设备可将小区中的400个UE均调度到BWP1上。随后接入网设备确定小区的负载等级由轻负载变为中负载，比如小区内处于RRC连接态的UE的数量增大到700个，接入网设备可以向该700个UE发送BWP信息2，该700个UE可从当前工作的BWP1上切换至BWP2。该700个UE可根据配置信息12确定PDCCH资源。
在另一个具体实现方式中，小区的负载降低时，接入网设备可以向UE发送第一BWP信息。UE在接收到该第一BWP信息之后，从当前工作的第二BWP切换至第一BWP，并确定出第一BWP对应的第一配置信息，根据该第一配置信息确定PDCCH资源，在该PDCCH资源上检测PDCCH。上述实施例中，第一BWP对应的PDCCH资源小于第二BWP对应的PDCCH资源，有助于节省资源。
再结合表4举例，小区的负载等级为中负载，比如小区内处于RRC连接态的UE有700个，接入网设备可将小区中的700个UE均调度到BWP2上。随后小区中有部分UE由RRC连接态进入RRC空闲态或RRC非激活态，或者有部分UE移动至其他小区，接入网设备确定小区的负载等级由中负载变为轻负载，比如小区内处于RRC连接态的UE的数量减小到400个，接入网设备可以向该400个UE发送BWP信息1，该400个UE根据该BWP信息1的指示，从当前工作的BWP2上切换至BWP1。进一步的，该400个UE可根据配置信息11确定PDCCH资源。
结合图6示例性示出的接入网设备配置与调度PDCCH资源的示意图进一步解释。
预先说明的是，如图6中包括多个方块(比如加粗部分表示一个方块)，该多个方块可理解为接入网设备为UE配置的资源。具体的，该方块的横坐标指示时域资源(比如一个slot)，方块的纵坐标指示频域资源(比如小区带宽)。每个方块中包括阴影区域和非阴影区域，阴影区域指示接入网设备为UE配置的PDCCH资源，而非阴影区域指示的资源可用于接入网设备与UE之间进行PDSCH传输。需要指出的是，该说明同样适用于其他接入网设备配置与调度PDCCH资源的示意图中。
图6可以分为资源配置过程和资源切换过程，其中，资源配置过程可理解为接入网设备向UE发送第一信息的过程，资源切换过程可理解为接入网设备在确定小区负载发生变化之后，向小区中UE指示第一指示信息的过程。需要指出的是，该说明同样适用于其他接入网设备配置与调度PDCCH资源的示意图中。
在资源配置过程中，接入网设备可以通过RRC信令向UE发送第一信息，相应的，UE通过RRC信令接收来自接入网设备的第一信息。该第一信息中可包括BWP1、BWP2和BWP3分别对应的配置信息11、配置信息12和配置信息13。该配置信息11、配置信息12和配置信息13可分别指示接入网设备为UE配置的PDCCH资源。具体的：
配置信息指示的PDCCH资源中所包括的频域资源可参见阴影区域在纵坐标上占用的方块比例，比如配置信息12指示的频域资源在纵坐标上占满方块，即表征该频域资源占用的带宽与方块指示的带宽(比如小区带宽)相同。如图6中，配置信息11、配置信息12和配置信息13指示的PDCCH资源可包括相同的带宽，该带宽可以是小区带宽。
配置信息指示的PDCCH资源中所包括的时域资源可参见阴影区域在横坐标上阴影块的个数，其中一个阴影块可代表一个符号，比如配置信息12指示的时域资源中包括2个符号，该2个符号可占用slot中的第1个和第2个符号。同理，配置信息11指示的时域资源包括slot中的第1个符号，配置信息13指示的时域资源包括slot中的第1个符号、第2个符号和第3个符号。
在资源切换过程中，当小区负载等级为轻负载时，接入网设备调度小区中的UE工作在BWP1上，相应的，小区中的UE根据配置信息11确定用于检测PDCCH的资源。当小区负载等级由轻负载变为中负载时，接入网设备将小区中的UE由BWP1调度至BWP2，相应的，小区中的UE根据配置信息12确定用于检测PDCCH的资源(即第一资源)。
情况2，第一信息中各配置信息可对应于相同大小的资源。
比如表5中多个BWP信息包括BWP信息1、BWP信息2和BWP信息3，该BWP信息1、BWP信息2和BWP信息3分别为BWP1、BWP2、BWP3对应的BWP信息，且分别对应于配置信息21、配置信息22和配置信息23。
示例性的，配置信息21对应于1个符号和20MHz，配置信息21可指示PDCCH在时域上占用slot中的第1个符号，以及在频域上占用20MHz；
配置信息22对应于1个符号和20MHz，配置信息22可指示PDCCH在时域上占用slot中的第2个符号，以及在频域上占用20MHz；
配置信息23对应于1个符号和20MHz，配置信息23可指示PDCCH在时域上占用slot中的第3个符号，以及在频域上占用20MHz。
表5
指示信息 配置信息 符号数 资源带宽
BWP信息1 配置信息21 1 20MHz
BWP信息2 配置信息22 1 20MHz
BWP信息3 配置信息23 1 20MHz
可以理解，接入网设备可以为UE配置最大PDCCH资源(即第二资源)，该第二资源可由多个配置信息来指示。结合表5中例子，该第二资源可以由配置信息21、配置信息22和配置信息23来共同指示，第二资源在时域上占用slot中的第1个符号、第2个符号和第3个符号，以及在频域上占用20MHz。示例性的，第二资源可包括配置信息22指示的资源，也可包括配置信息21指示的资源，还可包括配置信息23指示的资源。
在小区的负载信息发生变化的情况下，比如小区的负载等级由轻负载变为中负载，再比如小区的负载等级由重负载变为中负载，接入网设备可以根据当前小区的负载信息来确定目标UE以及用于目标UE传输PDCCH的资源大小，并将该资源大小对应的指示信息(即第一BWP信息)发送给目标UE，该第一BWP信息可用于指示目标UE切换工作BWP。
一个具体实现方式中，小区的负载增大时，接入网设备可以从小区UE中确定出目标UE，向目标UE发送第一BWP信息。目标UE在接收到该第一BWP信息之后，从当前工作的第二BWP切换至第一BWP，目标UE还可根据第一BWP信息和第一信息，确定第一信息中与第一BWP信息相对应的第一配置信息，目标UE根据该第一配置信息确定PDCCH资源，并在该PDCCH资源上检测PDCCH。在该方式中，接入网设备将小区中的目标UE由第二BWP调度至第一BWP上，而小区中的另外一部分UE仍工作在第二BWP上，通过该方式，可以将小区中的UE分散至不同的BWP上，则工作在不同BWP上的UE可以使用不同的PDCCH资源进行检测。
结合表5举例，BWP信息1对应的资源可用于600个UE检测。小区中有1000个UE在BWP1上工作，接入网设备可以向该1000个UE中的400个UE(即目标UE)发送BWP信息2。该400个UE根据BWP信息2，从当前工作的BWP1上切换至BWP2。从而小区中的1000个UE可分散至不同的BWP上，具体的，调度至BWP2上的400个UE可根据配置信息22确定PDCCH资源，而仍工作在BWP1上的600个UE可根据配置信息21确定PDCCH资源。
在另一个具体实现方式中，小区的负载降低时，接入网设备可以向小区的目标UE发 送第一BWP信息。目标UE在接收到该第一BWP信息之后，从当前工作的第二BWP切换至第一BWP，并确定出第一BWP对应的第一配置信息，根据该第一配置信息确定PDCCH资源，在该PDCCH资源上检测PDCCH。在该方式中，接入网设备将小区中的目标UE由第二BWP调度至第一BWP上，从而目标UE可以与本来在第一BWP上工作的UE工作在同一个BWP上，通过该方式，可以将小区中的分散于不同BWP上UE汇集至同一个BWP上，则工作在同一个BWP上的UE可以使用相同的PDCCH资源进行检测，从而有利于提高资源的利用率。
仍结合表5举例，BWP信息1对应的资源可用于600个UE检测。小区中有200个UE在BWP1上工作，有300个UE在BWP2上工作，接入网设备可以向该在BWP2上工作的300个UE发送BWP信息1，该300个UE可从当前工作的BWP2上切换至BWP1，从而在BWP1上工作有500个UE，该500个UE可根据配置信息21确定PDCCH资源。
结合图7示例性示出的接入网设备配置与调度PDCCH资源的示意图进一步解释。图7同样可以分为资源配置过程和资源切换过程：
在资源配置过程中，接入网设备可以给UE配置BWP1、BWP2和BWP3分别对应的配置信息21、配置信息22和配置信息23。
如图7的资源配置过程中，BWP1对应的配置信息21指示的时域资源中包括第1个符号，BWP2对应的配置信息22指示的时域资源中包括第2个符号，BWP3对应的配置信息23指示的时域资源中包括第3个符号。
在资源切换过程中，当小区负载等级为轻负载时，接入网设备调度小区中的UE工作在BWP1上，相应的，小区中的UE根据配置信息21确定用于检测PDCCH的资源。当小区负载等级由轻负载变为中负载时，接入网设备调度小区中的一部分UE(即目标UE)由BWP1调度至BWP2，相应的，小区中的工作在BWP2上的UE根据配置信息22确定用于检测PDCCH的资源(即第一资源)。而小区中的仍工作在BWP1上的UE可根据配置信息21确定用于检测PDCCH的资源。
上述技术方案中，接入网设备可给每个UE配置多个不同的BWP，每个BWP可独立配置各自对应的PDCCH配置信息，即每个BWP可以对应有各自的符号数和频域带宽。接入网设备可以通过调度UE切换工作BWP的方式，来为UE指示对应的PDCCH的配置信息。在小区负载发生变化时，接入网设备可快速高效的为UE指示与变化之后的小区负载相对应的第一BWP信息，有助于接入网设备与UE之间的用于传输PDCCH的资源可较好的适用于小区负载。进一步的，第一BWP信息可以是接入网设备通过DCI向UE发送的，该第一BWP信息可实现TTI粒度的配置。
需要补充的是，在第一资源小于第二资源时，接入网设备还可指示第二资源中除第一资源以外的其他资源，可用于接入网设备与UE之间传输PDSCH。
结合上述表4示例性示出的例子，比如接入网设备调度UE工作在BWP2上，则UE可根据配置信息12确定出第一资源在时域上包括2个符号(即第1、2个符号)，那么接入网设备可以在第3个符号中，配置UE传输PDSCH，从而有助于提高资源的利用率。该PDSCH可由第1、2个符号上传输的PDCCH调度。
在一种可能的方式中，PDCCH中承载有用于指示PDSCH位置的指示信息，该指示信息可以是速率匹配资源图样信息(rate matching pattern，RM pattern)，或者该指示信息还可以是调度起始符号和长度指示值(start and length indicator value，SLIV)。
如下以指示信息是速率匹配图样信息为例说明，接入网设备预先向UE发送多个速率匹配图样信息和该多个速率匹配图样信息对应的速率匹配图样，其中速率匹配图样信息可以是标识，速率匹配图样信息对应的速率匹配图样可用于指示PDCCH和PDSCH之间的图样关系。也可以理解，速率匹配图样指示的PDCCH的子信道位置可作为打孔位置，而剩余的子信道位置可以用于传输PDSCH。
示例性的，接入网设备可以将多个速率匹配图样信息和该多个速率匹配图样信息对应的速率匹配图样承载于第一信息中发送给UE。接入网设备也可以将多个速率匹配图样信息和该多个速率匹配图样信息对应的速率匹配图样作为单独的消息发送给UE，示例性的，该单独的消息可以是RRC信令。
当UE从PDCCH中获取到速率匹配图样信息时，可以根据速率匹配图样信息确定与该速率匹配图样信息相对应的速率匹配图样，然后根据该速率匹配图样确定PDSCH的位置。参照图8示例性示出的多个速率匹配图样的示意图，该示意图中包括速率匹配图样信息1对应的速率匹配图样、速率匹配图样信息2对应的速率匹配图样、速率匹配图样信息3对应的速率匹配图样和速率匹配图样信息4对应的速率匹配图样。对于图8示出的每个速率匹配图样来说，速率匹配图样中可包括阴影区域和非阴影区域，其中阴影区域可用于传输PDCCH，非阴影区域可用于传输PDSCH。
比如UE从PDCCH中获取到速率匹配图样信息1，那么UE可以根据速率匹配图样信息1对应的速率匹配图样，确定PDSCH对应的时域资源的起始符号是第2个符号，PDSCH对应的频域资源占用20Mhz。再比如，UE从PDCCH中获取到速率匹配图样信息4，那么UE可以根据速率匹配图样信息4对应的速率匹配图样，确定PDSCH对应的时域资源的起始符号是第1个符号，频域资源占用10Mhz，而且在第3个符号以及第3个符号之后的时域资源中，对应的频域资源占用20Mhz。
接入网设备在向UE指示速率匹配资源图样信息时，可以结合小区中UE检测PDCCH对应的PDCCH资源来确定。结合表4中例子说明，在接入网设备向小区中UE指示BWP信息2时，小区中UE均工作在BWP 2上，即小区中UE均可在时域上的第1个符号和第2个符号，以及在频域上的20Mhz检测PDCCH。接入网设备可在PDCCH中承载速率匹配图样信息2，或者还可以在PDCCH中承载速率匹配图样信息4，从而UE在解析出PDCCH之后，可以根据PDCCH确定PDSCH的位置，进而解析PDSCH。
需要说明的是，在上述表5相关方式中，接入网设备在向UE指示速率匹配图样信息之前，还可以确定小区中UE工作在不同的BWP上，比如有一部分UE工作在BWP 1上，即该部分UE可在时域上的第1个符号，以及在频域上的20Mhz检测PDCCH。而有另一部分UE工作在BWP 2上，即该部分UE可在时域上的第2个符号，以及在频域上的20Mhz检测PDCCH。接入网设备可为工作在不同BWP上的UE指示相同的PDSCH资源，即可以通过相同的速率匹配图样信息来指示。示例性的，接入网设备可向小区中工作在BWP 1上的UE发送PDCCH，该PDCCH中可承载速率匹配图样信息2，同样的，接入网设备也可向小区中工作在BWP2上的UE发送PDCCH，该PDCCH中也可承载速率匹配图样信息2，从而避免工作在BWP 1上的UE确定出的PDSCH资源与工作在BWP2上的UE确定出的PDCCH资源相冲突。
上述仅是以第一指示信息是第一BWP信息为例说明，当第一指示信息是第一检测资源图样信息时，第一检测资源图样信息对应的资源信息可以是检测资源图样。在该实现方 式中，接入网设备可以预先向UE发送第二资源的配置信息，其中该第二资源的配置信息可以是承载于单独的一条RRC信令中发送至UE，也可以是和第一信息承载于同一条RRC信令中发送至UE。当UE接收到来自接入网设备的第一检测资源图样信息时，可以确定第一检测资源图样信息对应的检测资源图样，然后再根据检测资源图样和第二资源的配置信息，确定出第一资源。具体可以参照上述实施例中的描述。
当然，上述实现方式也仅是示例性的说明，第一信息中包括的指示信息和指示信息对应的资源信息还可以是其他方式，比如多个指示信息指示的资源信息中，有两个资源信息指示的资源大小不同，而其他两个资源信息指示的资源大小相同。接入网设备也可以根据当前的小区的负载信息，确定出第一指示信息(即第一BWP信息，或者第一检测资源图样信息)，并将该第一指示信息指示给小区中的所有UE或者目标UE。
此外，本申请还提供一种通信资源的确定方法，该方法可用于在小区负载发生变化时，接入网设备与终端设备之间的用于传输PDCCH的资源可较好的适用于小区负载。该方法可以由图1示例性示出的终端设备(即UE)和接入网设备执行。
在该方法中，接入网设备可预先确定第四信息，然后将该第四信息配置给UE。第四信息中可包括一个或多个资源信息，资源信息可以是PDCCH的配置信息，PDCCH的配置信息中可包括有CORESET和SS。第四信息中包括多个资源信息的情况下，该多个资源信息分别指示的多个PDCCH资源的资源大小可以相同或不同。多个PDCCH资源中包括的符号数可以相同或不同；多个PDCCH资源中包括的带宽可以相同或不同。
在一种可能方式中，第四信息中包括的一个或多个资源信息指示的PDCCH资源可对应于第1个符号和20Mhz，第2个符号和20Mhz，第3个符号和20Mhz，第1、2个符号和20Mhz，第1、2、3个符号和20Mhz中的一个或多个。
在示例1中，第四信息中包括的3个资源信息，可分别对应于第1个符号和20Mhz，第2个符号和20Mhz，第3个符号和20Mhz。
在示例2中，第四信息中包括的3个资源信息，可分别对应于第1个符号和20Mhz，第1、2个符号和20Mhz，第1、2、3个符号和20Mhz。
在一种可能的方式中，接入网设备可以将该第四信息通过高层信令配置给UE，高层信令比如是RRC信令。示例性的，接入网设备可向UE发送RRC重配置消息，该RRC重配置消息中包括该第四信息。
基于第四信息中包括一个资源信息，还是多个资源信息，如下分情况说明：
情况a、第四信息中包括多个资源信息。
接入网设备向UE发送PDCCH之前，可以从多个资源信息中选择出其中一个资源信息，然后在该选择的资源信息指示的资源上向UE发送PDCCH。UE由于不知道接入网设备具体在哪个资源上发送，所以通过全量检测的方式，在多个资源信息分别指示的资源上进行检测，确定在哪个资源上可以检测到PDCCH。
如下结合图9示出的再一种通信资源的确定方法的流程中：
步骤901，接入网设备根据小区的负载信息，从多个资源信息中确定第一资源信息，第一资源信息用于指示第一资源。
在一种可能的实现方式中，接入网设备在确定UE接入至小区时，或者接入网设备在确定小区的负载信息发生变化时，接入网设备可以根据小区的负载信息，从多个资源信息 中确定出第一资源信息，其中第一资源信息指示的PDCCH资源大小可符合小区的负载信息对PDCCH资源大小的需求。
步骤902，UE根据多个资源信息确定多个资源信息分别指示的PDCCH资源。示例性的，多个资源信息中的每个资源信息中可包括有各自的CORESET和SS，UE可以根据每个资源信息中包括的CORESET和SS，确定该资源信息指示的PDCCH资源，从而UE确定出多个资源信息分别指示的PDCCH资源。
步骤903，接入网设备在第一资源上向UE发送PDCCH。
步骤904，UE在多个资源信息指示的PDCCH资源中进行检测，其中，多个资源信息中的第一资源信息指示第一资源，第一资源中承载有PDCCH。
本申请中，不限定步骤902与步骤901的顺序。
上述步骤902至步骤904中，UE根据多个资源信息确定出多个资源信息分别对应的PDCCH资源，并在每个PDCCH资源上检测PDCCH，确定是否检测到PDCCH。比如，多个资源信息包括有资源信息31、资源信息32和资源信息33，UE可以在资源信息31指示的资源上检测PDCCH，确定是否检测到PDCCH；以及在资源信息32指示的资源上检测PDCCH，确定是否检测到PDCCH；以及在资源信息33指示的资源上检测PDCCH，确定是否检测到PDCCH。示例性的，接入网设备在资源信息32指示的资源上向UE发送PDCCH，则UE可在资源信息32指示的资源检测到PDCCH，而在资源信息31指示的资源上和在资源信息33指示的资源上检测不到PDCCH。
结合图10示例性示出的接入网设备配置与调度PDCCH资源的示意图解释说明，接入网设备给UE配置的第四信息中包括多个资源信息，该多个资源信息可包括资源信息31、资源信息32和资源信息33，其中资源信息31对应于第1个符号和20MHz，资源信息32对应于第1、2个符号和20MHz，资源信息33对应于第1、2、3个符号和20MHz。UE可以在该三个不同的PDCCH资源上检测PDCCH(即全量检测)。
在轻负载情况下，接入网设备可在资源信息31对应的资源上发送PDCCH，UE虽然执行了全量检测，但仅能从资源信息31对应的资源上检测到PDCCH，UE在资源信息32对应的资源和资源信息33对应的资源上的检测属于无效检测。
在中负载情况下，接入网设备可在资源信息32对应的资源上发送PDCCH，UE虽然执行了全量检测，但仅能从资源信息32对应的资源上检测到PDCCH，UE在资源信息31对应的资源和资源信息33对应的资源上的检测属于无效检测。
在重负载情况下，接入网设备可在资源信息33对应的资源上发送PDCCH，UE虽然执行了全量检测，但仅能从资源信息33对应的资源上检测到PDCCH，UE在资源信息32对应的资源和资源信息31对应的资源上的检测属于无效检测。
需要指出的是，接入网设备还可以根据小区的负载信息，从小区中确定出目标UE，然后确定目标UE对应的第一资源信息，并在该第一资源信息指示的第一资源上，向小区中目标UE发送PDCCH。对于小区中的目标UE，目标UE在多个资源信息分别指示的资源上进行全量检测，目标UE可在第一资源信息指示的第一资源上检测到PDCCH。而对于小区中的除目标UE以外的其他UE，接入网设备还可以在原有的资源上向该其他UE发送PDCCH。该方式可适用于多个资源信息指示相同大小资源的情况中，示例性的，该多个资源信息可包括资源信息41、资源信息42和资源信息43，其中资源信息41对应于第1个符号和20MHz，资源信息42对应于第2个符号和20MHz，资源信息43对应于第3个符 号和20MHz。UE可以在该三个不同的PDCCH资源上检测PDCCH(即全量检测)。
举例来说，小区的负载等级为轻负载，比如小区内处于RRC连接态的UE有400个，接入网设备可在资源信息41指示的资源上向小区内的400个UE发送PDCCH，该400个UE可经过全量检测，从资源信息41指示的资源上检测到PDCCH。随后接入网设备确定小区的负载等级由轻负载变为中负载，比如小区内处于RRC连接态的UE的数量增大到700个，则接入网设备可从700个UE中确定出200个目标UE，然后通过资源信息42指示的资源向该200个目标UE发送PDCCH，则该200个目标UE可经过全量检测，从资源信息42指示的资源上检测到PDCCH。而剩余的500个UE仍然可经过全量检测，从资源信息41指示的资源上检测到PDCCH。
还可以理解，第四信息还可指示最大PDCCH资源(即第二资源)，该第二资源可包括其他资源信息指示的资源。结合图10示出的例子，第四信息指示的多个资源信息中包括资源信息31、资源信息32和资源信息33，资源信息33为第二资源信息，该资源信息33指示的资源可包括资源信息32指示的资源，也可包括资源信息31指示的资源。
在第一资源小于第二资源时，接入网设备还可指示第二资源中除第一资源以外的其他资源，可用于接入网设备与UE之间传输PDSCH。在一种可能的方式中，PDCCH中承载有用于指示PDSCH位置的指示信息，该指示信息可以是速率匹配资源图样信息，或者该指示信息还可以是调度起始符号和长度指示值，该实现方式具体可参见图4相关实施例中的描述。
上述技术方案中，接入网设备可以为UE配置多个不同的资源信息，接入网设备在确定小区的负载信息发生变化时，确定与小区的负载信息相对应的资源信息，然后在该资源信息指示的资源上向UE发送PDCCH。UE在多个不同的资源信息分别指示的资源上检测PDCCH，确定是否在某个资源上检测到PDCCH。通过该方式，接入网设备无需指示UE变更PDCCH资源，从而有助于实现接入网设备与UE之间更灵活的传输PDCCH。
情况b、第四信息中包括一个资源信息。
该资源信息可以理解为是第二资源信息，第二资源信息可用于指示最大PDCCH资源(即第二资源)。示例性的，第二资源信息可用于指示第1个符号和20Mhz，第1、2个符号和20Mhz，第1、2、3个符号和20Mhz中的一个。
接入网设备根据小区的负载信息，确定第一资源信息，第一资源信息用于指示第一资源，该第一资源包含于第二资源中。UE可以全量检测第二资源，然后在第一资源中检测到PDCCH。该PDCCH中可以包括用于指示PDSCH位置的指示信息，该指示信息可以是速率匹配资源图样信息，或者该指示信息还可以是调度起始符号和长度指示值。UE根据该指示信息从指示信息指示的资源上检测PDSCH。
结合图11举例来说，第二资源信息指示的第二资源对应于第1、2、3个符号和20Mhz，接入网设备在第1、2、3个符号和10Mhz上向UE发送PDCCH。该PDCCH中可以包括速率匹配图样信息，该速率匹配图样信息可用于指示如图11所示的速率匹配图样。UE在第1、2、3个符号和20Mhz上全量检测PDCCH，然后检测到PDCCH，该PDCCH中可包括速率匹配图样信息，UE根据速率匹配图样信息指示的速率匹配图样和第二资源，确定出PDSCH的位置，并在该位置上解析PDSCH。参照图11示例性示出的箭头右侧的方块中，阴影区域指示PDCCH资源，非阴影区域指示PDSCH资源，UE可在非阴影区域指示的PDSCH资源上接收PDSCH。
上述技术方案中，接入网设备可以为UE配置最大PDCCH资源(即第二资源)，接入网设备在确定小区的负载信息发生变化时，确定与小区的负载信息相对应的第一资源，然后在第一资源上向UE发送PDCCH。UE在第二资源上检测PDCCH，接入网设备无需指示UE变更PDCCH资源，从而有助于实现接入网设备与UE之间更灵活的传输PDCCH。进一步的，接入网设备在PDCCH中携带用于指示PDSCH资源的指示信息，从而有助于提高资源的利用率。
