出于说明的目的，下文中以3GPP中的NR通信***为背景来描述本公开的实施例。然而，应当理解，本公开的实施例不限于该通信***，而是可以被应用到任何存在类似问题的通信***中，例如无线局域网(WLAN)、有线通信***、或者将来开发的其他通信***等。
在本公开中使用的术语“终端设备”指能够与网络设备之间或者彼此之间进行有线或无线通信的任何终端设备。终端设备有时可以称为用户设备(User Equipment，UE)。终端设备可以是任意类型的移动终端、固定终端或便携式终端。作为示例，终端设备可以包括移动手机、站点、单元、设备、移动终端(Mobile Terminal，MT)、订阅台、便携式订阅台、互联网节点、通信器、台式计算机、膝上型计算机、笔记本计算机、平板计算机、个人通信***设备、个人导航设备、个人数字助理(Personal Digital Assistant，PDA)、定位设备、无线电广播接收器、电子书设备、游戏设备、物联网(Internet of Things，IoT)设备、车载设备、飞行器、虚拟现实(Virtual Reality，VR)设备、增强现实(Augmented Reality，AR)设备、可穿戴设备、5G网络中的终端设备或者演进的公用陆地移动网络(Public Land Mobile Network，PLMN)中的任何终端设备、可用于通信的其他设备、或者上述的任意组合。本公开的实施例对此并不做限定。
在本公开中使用的术语“网络设备”是可以用于与终端设备通信的实体或节点，例如可以是接入网设备。接入网设备可以是部署在无线接入网中为移动终端提供无线通信功能的装置，例如可以是无线接入网(Radio Access Network，RAN)网络设备。接入网设备可以包括 各种类型的基站。作为示例，接入网设备可以包括各种形式的宏基站、微基站、微微基站、毫微微基站、中继站、接入点、远程无线电单元(Remote Radio Unit，RRU)、射频头(Radio Head，RH)、远程无线电头端(Remote Radio Head，RRH)等等。在采用不同的无线接入技术的***中，接入网设备的名称可能会有所不同，例如在长期演进***(Long Term Evolution，LTE)网络中称为演进的节点B(evolved NodeB，eNB或eNodeB)，在3G网络中称为节点B(NodeB，NB)，在5G网络中可以称为g节点B(gNB)或NR节点B(NR NB)，等等。在某些场景下，接入网设备可以包含集中单元(Central Unit，CU)和/或分布单元(Distributed Unit，DU)。CU和DU可以放置在不同的地方，例如：DU拉远，放置于高话务量的区域，CU放置于中心机房。或者，CU和DU也可以放置在同一机房。CU和DU也可以为一个机架下的不同部件。为方便描述，本公开后续的实施例中，上述为终端设备提供无线通信功能的装置统称为网络设备，本公开的实施例不再具体限定。
下行物理信道对应于承载来自高层信息的一组资源单元(Resource Element，RE)。PDCCH是下行物理信道之一，其承载调度信息和其他控制信息。PDCCH可以承载关于上行数据和/或下行数据的调度信息，终端设备可以周期性地监听PDCCH以获取调度信息。如果终端设备监听到调度信息，则进一步地终端设备可以基于调度信息通过物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)接收下行数据，或者通过物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)发送上行数据。PDCCH还可以承载上行功率控制命令字、时隙格式等信息。承载不同的控制信息的PDCCH可以采用不同的无线网络临时标识(Radio Network Temporary Identifier，RNTI)进行加扰。
应注意的是，终端设备对PDCCH的监听(monitoring)也可以被称为侦听(listening)、检测(detecting)等，本公开的实施例对该术语不限定。
PDCCH在一个或多个连续的控制信道单元(Control Channel Element，CCE)的聚合上进行传输，其中一个CCE可以对应6个资源单元组(Resource Element Group，REG)。网络设备可以为终端设备配置至少一个搜索空间集(Search Space Set，SSS)，其中一个搜索空间集可以用于定义一组候选PDCCH。终端设备可以根据搜索空间集的配置信息确定PDCCH监听时机(Monitoring Occasion，MO)，进而可以在所确定的PDCCH监听时机上监听PDCCH，如图1所示，其中PDCCH监听时机也可以被称为PDCCH候选位置。
搜索空间集的配置信息可以包括以下中的至少一项：
(1)搜索空间集的标识信息，用于标识搜索空间集。
(2)与搜索空间集关联的控制资源集(control resource set，CORESET)的标识信息。CORESET表示用于承载PDCCH的时频资源集，一个CORESET在频域上由若干个连续的或非连续的资源块(Resource Block，RB)组成，时域上由连续的1或多个符号组成。
(3)PDCCH监听周期(例如表示为Ks)和偏移(例如表示为Os)，其中Ks和Os的量纲可以为时隙(slot)，或者可选地，Os的量纲可以为符号。
(4)时隙内PDCCH监听图案(pattern)，或者称为时隙内PDCCH监听符号，用于指示搜索空间集关联的CORESET在时隙内监听PDCCH的起始符号。
(5)持续时间(例如表示为Ts)，用于指示搜索空间集存在的连续的时隙的个数，其中Ts小于Ks，Ts的取值可以为1个时隙。
(6)聚合等级以及各聚合等级对应的候选PDCCH(PDCCH candidate)的个数。
(7)搜索空间集类型指示信息，用于指示搜索空间集是公共搜索空间集(Common Search  Space set，CSS set)，或者是用户设备专用搜索空间集(UE-specific Search Space set，USS set)。示例性地，公共搜索空间集可以简称为CSS，用户设备专用搜索空间集可以简称为USS。
示例性地，公共搜索空间集包括类型3公共搜索空间集(type-3 CSS)，其可以主要用于监听承载被下列任一无线网络临时标识符(Radio Network Temporary Identifier，RNTI)所加扰的DCI的PDCCH：中断-RNTI(Interruption RNTI，INT-RNTI)、时隙格式指示-RNTI(Slot Format Indication-RNTI，SFI-RNTI)、传输功率控制-物理上行链路共享信道-RNTI(Transmit Power Control-Physical Uplink Shared Channel-RNTI，TPC-PUSCH-RNTI)、传输功率控制-物理上行链路控制信道-RNTI(Transmit Power Control-Physical Uplink Control Channel-RNTI，TPC-PUCCH-RNTI)、传输功率控制-探测参考信号-RNTI(Transmit Power Control-Sounding Reference Symbols-RNTI，TPC-SRS-RNTI)、或者取消指示-RNTI(Cancellation Indication-RNTI，CI-RNTI)、主小区上的小区-RNTI(Cell-RNTI，C-RNTI)、调制与编码策略-C-RNTI(Modulation and Coding Scheme-Cell-RNTI，MCS-C-RNTI)、配置的调度-RNTI(Configured Scheduling-RNTI，CS-RNTI)、功率节省-RNTI(Power Saving-RNTI，PS-RNTI)等。
示例性地，用户设备专用搜索空间集可以用于监听承载被下列任一RNTI所加扰的DCI的PDCCH：C-RNTI、MCS-C-RNTI、半持续-信道状态指示-RNTI(Semi Persistent-Channel State Indication-RNTI，SP-CSI-RNTI)、CS-RNTI、侧链路-RNTI(Side Link-RNTI，SL-RNTI)、SL-CS-RNTI、侧链路半持续调度车辆-RNTI(SL Semi-Persistent Scheduling V-RNTI)等。
并且，若搜索空间集的类型为CSS，网络设备还会配置在PDCCH候选位置监听的下行链路控制信息(Downlink Control Information，DCI)格式(format)，例如，可以为DCI格式0_0、DCI格式1_0、DCI格式2_0、DCI格式2_1、DCI格式2_2、DCI格式2_3、DCI格式2_4、DCI格式2_5或DCI格式2_6等。若搜索空间集的类型为USS，则网络设备还会配置在PDCCH候选位置监听的DCI格式，例如，可以为DCI格式0_0、DCI格式1_0、DCI格式0_1、DCI格式1_1、DCI格式0_2、DCI格式1_2、DCI格式3_0、或DCI格式3_1等。示例性地，关于不同的DCI格式所对应的不同的使用如下面的表1所示，但是应理解，表1仅是示意，实际场景中DCI格式的种类可以更多或更少，在一些场景下，某DCI格式可以具有与表1中不同的使用。
如此，终端设备可以根据搜索空间集的配置信息来监听PDCCH。具体而言，终端设备可以基于搜索空间集的配置信息所包括的PDCCH监听周期和偏移、时隙内PDCCH监听图案等，在与搜索空间集关联的CORESET上进行PDCCH监听。

可见，终端设备可以根据PDCCH监听周期，周期性地监听PDCCH。但是，在网络设备与终端设备之间不存在待传输业务时，终端设备的周期性监听会造成功耗浪费。为了达到节省终端功耗的目的，可以通过跳过PDCCH监听机制或者搜索空间集组切换机制来尽可能减少不必要的PDCCH监听。
跳过(skip)PDCCH监听机制
具体而言，网络设备可以通过DCI指示终端设备在接下来的一段时间内跳过PDCCH的监听(或者在一段时间内停止监听PDCCH，或者在一段时间内不监听PDCCH)。
图2示出了跳过PDCCH监听200的示意图。参见图2，假设在PDCCH监听时机210，终端设备通过监听PDCCH获取来自网络设备的DCI，且该DCI指示终端设备在接下来的一段时间(表示为Tskip)内跳过PDCCH的监听。那么在Tskip内的220-250处终端设备不监听PDCCH，而在经过Tskip之后在PDCCH监听时机260继续监听PDCCH。可理解，图2中的220-250是按照搜索空间集的配置信息确定的、被跳过监听的PDCCH监听时机。
另外，示例性地，被跳过的时间段(skipped duration)Tskip可以通过DCI指示，和/或通过无线资源控制(Radio Resource Control，RRC)信令配置或者协议预定义。例如，RRC信令可以配置多个被跳过的时间段的取值，并且通过DCI指示多个取值中的其中一个取值作为当前的被跳过的时间段。
应注意的是，跳过PDCCH监听包括跳过类型3公共搜索空间集上的PDCCH监听和用户设备专用搜索空间集上的PDCCH监听。对于其他类型的公共搜索空间集，例如，类型0、类型0A、类型1、类型2公共搜索空间集，终端设备可以跳过或不跳过C-RNTI、MCS-C-RNTI或CS-RNTI加扰的DCI的PDCCH监听，本公开的实施例不限定。对于类型0、类型0A、类型1、类型2公共搜索空间集，终端设备是否监听SI-RNTI、RA-RNTI、TC-RNTI或P-RNTI加扰的DCI的PDCCH，本公开的实施例不限定。
类型0和类型0A公共搜索空间集可以用于监听***信息-RNTI(System Information RNTI， SI-RNTI)加扰的DCI的PDCCH；类型1公共搜索空间集可以用于监听随机接入-RNTI(Random Access-RNTI，RA-RNTI)、消息B-RNTI(MessageB-RNTI，MsgB-RNTI)、或临时小区-RNTI(Temporary Cell-RNTI，TC-RNTI)加扰的DCI的PDCCH；类型2公共搜索空间集可以用于监听寻呼-RNTI(Paging-RNTI，P-RNTI)加扰的DCI的PDCCH。对于类型0、类型0A、类型1、类型2公共搜索空间集，在终端设备监听SI-RNTI、RA-RNTI、MsgB-RNTI、或P-RNTI加扰的DCI的PDCCH的时隙上，终端设备可以监听C-RNTI、MCS-C-RNTI或CS-RNTI加扰的DCI(DCI格式0_0和DCI格式1_0)的PDCCH。
如此，终端设备通过在时间段Tskip内跳过PDCCH监听，能够进入睡眠状态，而达到节省功耗的目的。
应注意的是，终端设备跳过PDCCH监听也可以被称为停止(stop)PDCCH监听、不监听PDCCH等，本公开的实施例对该术语不限定。
搜索空间集组(Search Space Set Group，SSSG)的切换机制
参照上述结合图1的部分，针对一个下行带宽部分(Band Width Part，BWP)，网络设备可以为终端设备配置多个搜索空间集(SS set)。进一步地，可以将多个搜索空间集进行分组，例如分为2组或3组或更多组。
在被分组的情况下，搜索空间集的配置信息还可以包括该搜索空间集属于哪一个SSSG的指示信息。举例而言，假设一个下行BWP上的搜索空间集被分为2组，表示为SSSG0和SSSG1。那么可以指示搜索空间集是属于第一个组(SSSG0)还是属于第二个组(SSSG1)。举例而言，假设被分为3组，表示为SSSG0、SSSG1和SSSG2。那么可以指示搜索空间集是属于第一个组(SSSG0)、第二个组(SSSG1)还是第三个组(SSSG2)。这样，终端设备只需要根据所指示的SSSG中的搜索空间集来监听PDCCH，这样能够减小对PDCCH监听的次数等，从而降低功耗。可理解，某个搜索空间集可能同时属于两个或三个不同的SSSG。
可理解，对于没有被分组的SS set，终端设备仍按照SS set的配置信息监听PDCCH，本公开的实施例不限定。
图3示出了对一个下行BWP内4个搜索空间集进行分组300的示意图。参照图3，按照PDCCH监听周期的稀疏程度，可以将4个搜索空间集分为2组：SSSG0和SSSG1，其中SSSG0包括搜索空间集3和搜索空间集4，SSSG1包括搜索空间集1和搜索空间集2。
举例而言，假设终端设备被指示的搜索空间集组是SSSG1，那么终端设备可以根据属于SSSG1的搜索空间集1和搜索空间集2来监听PDCCH，而不需要根据搜索空间集3和搜索空间集4来监听PDCCH。由于属于SSSG1的搜索空间集的PDCCH监听周期更稀疏，因此能减少监听次数，降低功耗。
可选地，网络设备还可以指示终端设备切换搜索空间集组。作为示例，网络设备可以通过DCI中的比特域显式指示或者通过DCI隐式指示SSSG切换。
举例而言，假设搜索空间集被分为2组，SSSG0和SSSG1。显式指示的方式可以为：DCI中的特定比特域为“0”，指示终端设备根据属于SSSG0的搜索空间集来监听PDCCH；DCI中的特定比特域为“1”，指示终端设备根据属于SSSG1的搜索空间集来监听PDCCH。显式指示的方式或者还可以为：DCI中的特定比特域为“0”，指示终端设备根据属于当前SSSG的搜索空间集来监听PDCCH，即不切换SSSG；DCI中的特定比特域为“1”，指示终端设备进行SSSG切换(如果当前为SSSG0，则切换到SSSG1。或者如果当前为SSSG1，则切换到SSSG0)，并根据属于切换后SSSG的搜索空间集来监听PDCCH。隐式指示的方式可以为： 当前监听PDCCH的SSSG为SSSG0，终端设备监听到特定的DCI或者任意DCI，则切换到SSSG1，或者，当前监听PDCCH的SSSG为SSSG1，终端设备监听到特定的DCI或者任意DCI，则切换到SSSG0。
再举例而言，假设所有的搜索空间集被分为3组，SSSG0、SSSG1和SSSG2。显式指示的方式可以为：DCI中的特定比特域为“00”，指示终端设备根据属于SSSG0的搜索空间集来监听PDCCH；DCI中的特定比特域为“01”，指示终端设备根据属于SSSG1的搜索空间集来监听PDCCH；DCI中的特定比特域为“10”，指示终端设备根据属于SSSG2的搜索空间集来监听PDCCH：DCI中的特定比特域“11”可以为预留。显式指示的方式或者还可以为：DCI中的特定比特域为“0”，指示终端设备根据属于当前SSSG的搜索空间集来监听PDCCH，即不切换SSSG；DCI中的特定比特域为“1”，指示终端设备进行SSSG切换，并根据属于切换后SSSG的搜索空间集来监听PDCCH，其中SSSG切换可以是：如果当前为SSSG0，则切换到SSSG1；如果当前为SSSG1，则切换到SSSG2；如果当前为SSSG2，则切换到SSSG0。隐式指示的方式可以为：当前监听PDCCH的SSSG为SSSGx，终端设备监听到特定的DCI或者任意DCI，则切换到SSSGy，协议可以预定义SSSGx和SSSGy，例如SSSGx为SSSG0，SSSGy为SSSG1。
可选地，终端设备也可以基于定时器来切换SSSG。
举例而言，假设搜索空间集被分为2组，SSSG0和SSSG1。终端设备根据属于当前SSSG(以SSSG1为例)的搜索空间集来监听PDCCH，并启动定时器。在该定时器到期后，切换到SSSG0，终端设备根据属于SSSG0的搜索空间集来监听PDCCH。
再举例而言，假设搜索空间集被分为3组，SSSG0、SSSG1和SSSG2。终端设备根据属于当前SSSG(以SSSG1为例)的搜索空间集来监听PDCCH，并启动定时器。在该定时器到期后，切换到SSSG2，终端设备根据属于SSSG2的搜索空间集来监听PDCCH，并重置定时器。在该定时器到期后，切换到SSSG0，终端设备根据属于SSSG0的搜索空间集来监听PDCCH。再例如，当终端设备根据属于SSSG1的搜索空间集来监听PDCCH，并启动定时器。在该定时器到期后，切换到SSSG0，终端设备根据属于SSSG0的搜索空间集来监听PDCCH。当终端设备根据属于SSSG2的搜索空间集来监听PDCCH，并启动定时器。在该定时器到期后，切换到SSSG0，终端设备根据属于SSSG0的搜索空间集来监听PDCCH。即无论终端设备当前根据SSSG1的搜索空间集还是根据SSSG2的搜索空间集来监听PDCCH，在定时器到期后，都切换到SSSG0。
应注意的是，根据属于某一个SSSG的搜索空间集来监听PDCCH是指，根据属于某一个SSSG的类型3公共搜索空间集和用户设备专用搜索空间集来监听PDCCH。相应地，可理解，对多个搜索空间集进行分组是指对类型3公共搜索空间集和用户设备专用搜索空间集进行分组。
如此，终端设备通过切换SSSG，在激活的下行BWP内能够仅根据部分搜索空间集进行PDCCH监听，而达到节省功耗的目的。
基于上述的跳过PDCCH监听机制和搜索空间集组的切换机制，可以定义终端设备监听PDCCH的多种不同的监听行为，例如可以为下述的第一候选监听行为至第五候选监听行为。
第一候选监听行为：根据配置的搜索空间集监听PDCCH。具体而言，可以根据搜索空间集的配置信息来监听PDCCH，其中搜索空间集的配置信息包括PDCCH监听周期。可以被理解为，跳过PDCCH监听机制没有被激活或者没有被应用。在激活的下行BWP上终端设备没 有被配置搜索空间集组，则终端设备可以按照激活的下行BWP上配置的搜索空间集来监听PDCCH。如果在激活的下行BWP上终端设备被配置了搜索空间集组，则终端设备可以根据属于当前SSSG的搜索空间集来监听PDCCH。
第二候选监听行为：在被跳过的时间段(skipped duration)内跳过(或停止)监听PDCCH。即跳过PDCCH监听机制。
第三候选监听行为：根据属于SSSG0的搜索空间集来监听PDCCH。具体而言，停止根据SSSG1和SSSG2(如果有SSSG2)的搜索空间集监听PDCCH。
第四候选监听行为：根据属于SSSG1的搜索空间集来监听PDCCH。具体而言，停止根据SSSG0和SSSG2(如果有SSSG2)的搜索空间集监听PDCCH。
第五候选监听行为：根据属于SSSG2的搜索空间集来监听PDCCH。具体而言，停止根据SSSG0和SSSG1的搜索空间集监听PDCCH。
在一些示例中，可以将第一候选监听行为表示为Behavior 1，将第二候选监听行为表示为Behavior 1A，将第三候选监听行为表示为Behavior 2，将第四候选监听行为表示为Behavior 2A，将第五候选监听行为表示为Behavior 2B。
终端设备可以根据第一候选监听行为至第五候选监听行为中的其中一种来监听PDCCH，但是目前缺乏一种有效地方案来指示终端设备如何确定具体的监听行为。如果5种候选监听行为可以被任意指示，则增加了终端设备的实现复杂度，却没有带来额外的好处。
有鉴于此，本公开的实施例提供了一种网络设备向终端设备配置监听组合的方案，终端设备能够基于所配置的监听组合指示来确定监听行为，进而有效地减少终端设备的功耗并且降低终端设备的实现复杂度。
图4示出了本公开实施例可实现在其中的通信***400的一个示意图。图4所示的***400包括终端设备410和网络设备420，并且终端设备410能够与网络设备420进行通信。
可理解的是，图4仅是示意，本公开的实施例对终端设备410的类型、网络设备420的类型、通信***400所使用的通信协议等不作限定。下面将结合图4所示的通信***400描述本公开的一些实施例。
图5示出了根据本公开的一些实施例的终端设备410与网络设备420之间的过程500的交互信令图。
网络设备420向终端设备410发送510第一监听组合指示信息，第一监听组合指示信息指示至少两种候选监听行为。
本公开的实施例中所涉及的候选监听行为包括第一候选监听行为、第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为。第一候选监听行为表示根据配置的搜索空间集监听PDCCH，第二候选监听行为表示在预设时间段内停止监听PDCCH，第三候选监听行为表示根据第一搜索空间集组中的搜索空间集监听PDCCH，第四候选监听行为表示根据第二搜索空间集组中的搜索空间集监听PDCCH，第五候选监听行为表示根据第三搜索空间集组中的搜索空间集监听PDCCH。
具体而言，第一监听组合指示信息所指示的监听组合可以为以下中的一项：第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合。在另一示例中，第一监听组合指示信息所指示的监听组合可以为以下中的一项：第一监听组合、第二监听组合、第四监听组合或者第五监听组合。
第一监听组合包括第一候选监听行为和第二候选监听行为。第二监听组合包括第二候选 监听行为、第三候选监听行为和第四候选监听行为。第三监听组合包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为。第四监听组合包括第三候选监听行为和第四候选监听行为。第五监听组合包括第三候选监听行为、第四候选监听行为和第五候选监听行为。
在本公开的实施例中，网络设备420可以通过RRC信令向终端设备410显式地或隐式地指示第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合。
具体地，网络设备420可以基于跳过PDCCH监听机制和搜索空间集组的切换机制来配置该第一监听组合指示信息。举例而言，如果在激活的下行BWP上终端设备410没有被配置搜索空间集组，则第一监听组合指示信息所指示的至少两种候选监听行为不包括第三候选监听行为、第四候选监听行为和第五候选监听行为。如果在激活的下行BWP上搜索空间集被分为两组，则第一监听组合指示信息所指示的至少两种候选监听行为不包括第五候选监听行为。
在一些实施例中，RRC信令中的特定参数可以作为第一监听组合指示信息，来指示第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合中的任一种监听组合。
举例而言，特定参数可以为PDCCH监听适应(PdcchMonitorAdaptation)参数，那么网络设备420可以通过该PdcchMonitorAdaptation指示监听组合。例如，
Figure PCTCN2022118774-appb-000003
“ENUMERATED”表示枚举。“Beh 1and1A”表示包括第一候选监听行为和第二候选监听行为的第一监听组合。“Beh 1Aand2and2A”表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。“Beh 1Aand2and2Aand2B”表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。“Beh 2and2A”表示包括第三候选监听行为和第四候选监听行为的第四监听组合。“Beh 2and2Aand2B”表示包括第三候选监听行为、第四候选监听行为和第五候选监听行为的第五监听组合。
示例性地，该特定参数可以被包括在RRC的某个信元(Information Element，IE)中，例如被包括在PDCCH配置(PDCCH-Config)中，或者可以被包括在BWP下行链路专用(BWP-DownlinkDedicated)中，或者可以被包括在服务小区配置(ServingCellConfig)中。
可选地，在至少两种候选监听行为包括第二候选监听行为的情况下，网络设备420还可以进一步配置被跳过的时间段(skipped duration)。举例而言，网络设备420可以向终端设备410发送预设时间段的指示信息，从而终端设备410在预设时间段内停止监听PDCCH。可理解，预设时间段的指示信息可以被包括在PDCCH配置中，或者可以独立于PDCCH配置，本公开对此不限定。预设时间段的时间单元可以是秒、毫秒、帧、子帧、时隙、PDCCH监听时机的个数、或若干个连续时隙组成的时隙集合等，本公开对此不限定。
在一些实施例中，RRC信令可以直接通过列举的形式来配置至少两种候选监听行为，例如可以通过{参数1，参数2，…，参数N}的形式来配置，每一个参数对应一种候选监听行为。
具体而言，可以通过{Beh 1，Beh 1A}表示包括第一候选监听行为和第二候选监听行为的第一监听组合。通过{Beh 1A，Beh 2，Beh 2A}表示包括第二候选监听行为、第三候选监听行 为和第四候选监听行为的第二监听组合。通过{Beh 1A，Beh 2，Beh 2A，Beh 2B}表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。通过{Beh 2，Beh 2A}表示包括第三候选监听行为和第四候选监听行为的第四监听组合。通过{Beh 2，Beh 2A，Beh 2B}表示包括第三候选监听行为、第四候选监听行为和第五候选监听行为的第五监听组合。
在一些实施例中，网络设备420可以通过RRC信令中的第一特定参数和第二特定参数的结合来指示第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合中的任一种监听组合。
举例而言，第一特定参数可以为PDCCH监听适应(PdcchMonitorAdaptation)，第二特定参数可以为搜索空间集组的数量(nrofSearchSpaceSetGroup)。例如，
Figure PCTCN2022118774-appb-000004
“ENUMERATED”表示枚举，“INTEGER”表示整数。
具体而言，PdcchMonitorAdaptation指示“PdcchSkipping”表示包括第一候选监听行为和第二候选监听行为的第一监听组合。
具体而言，PdcchMonitorAdaptation指示“PdcchSkippingAndSearchSpaceSetGroupSwitching”且nrofSearchSpaceSetGroup指示“2”表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。或者可选地，PdcchMonitorAdaptation指示“PdcchSkippingAndSearchSpaceSetGroupSwitching”表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。
具体而言，PdcchMonitorAdaptation指示“PdcchSkippingAndSearchSpaceSetGroupSwitching”且nrofSearchSpaceSetGroup指示“3”表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。
具体而言，PdcchMonitorAdaptation指示“SearchSpaceSetGroupSwitching”且nrofSearchSpaceSetGroup指示“2”表示包括第三候选监听行为和第四候选监听行为的第四监听组合。
具体而言，PdcchMonitorAdaptation指示“SearchSpaceSetGroupSwitching”且nrofSearchSpaceSetGroup指示“3”表示包括第三候选监听行为、第四候选监听行为和第五候选监听行为的第五监听组合。
可选地，在至少两种候选监听行为包括第二候选监听行为的情况下，网络设备420还可以进一步配置被跳过的时间段(skipped duration)。举例而言，网络设备420可以向终端设备410发送预设时间段的指示信息，从而终端设备410在预设时间段内停止监听PDCCH。可理解，预设时间段的指示信息可以被包括在PDCCH配置中，或者可以独立于PDCCH配置(如通过另一配置信息进行发送)，本公开对此不限定。预设时间段的时间单元可以是秒、毫秒、帧、子帧、时隙、PDCCH监听时机的个数、或若干个连续时隙组成的时隙集合等，本公开对此不限定。
在一些实施例中，网络设备420可以通过RRC信令中的第三特定参数和第四特定参数的 结合来指示第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合中的任一种监听组合。
举例而言，第三特定参数可以指示停止PDCCH监听的被跳过的时间段(skipped duration)。第三特定参数可以被包括在PDCCH配置中，或者可以独立于PDCCH配置，本公开对此不限定。
举例而言，第四特定参数可以指示搜索空间集所属的SSSG的索引，其中，该索引可以为0、1、2中的至少一个。第四特定参数可以被包括在搜索空间集的配置信息中。以搜索空间集SS set 1为例，该搜索时空间集的配置信息可以包括第四特定参数，其指示该搜索空间集所属的SSSG的索引。
具体地，网络设备420配置了第三特定参数且没有配置第四特定参数，表示包括第一候选监听行为和第二候选监听行为的第一监听组合。网络设备420配置了第三特定参数且配置了第四特定参数，第四特定参数有0和1两种，表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。网络设备420配置了第三特定参数且配置了第四特定参数，第四特定参数有0、1和2三种，表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。网络设备420配置了第四特定参数且没有配置第三特定参数，第四特定参数有0和1两种，表示包括第三候选监听行为和第四候选监听行为的第四监听组合。网络设备420配置了第四特定参数且没有配置第三特定参数，第四特定参数有0、1和2三种，表示包括第三候选监听行为、第四候选监听行为和第五候选监听行为的第五监听组合。
附加地或可选地，网络设备420还可以向终端设备410发送搜索空间集的配置信息，该搜索空间集的配置信息可以包括以下中的至少一项：搜索空间集的标识信息、与搜索空间集关联的控制资源集、PDCCH监听周期和偏移、时隙内PDCCH监听图案、持续时间、聚合等级以及各聚合等级对应的候选PDCCH的个数、和搜索空间集类型指示信息等。
可选地，在本公开的一些实施例中，第一监听组合指示信息可以指示第一BWP的监听组合。并且网络设备420还可以向终端设备410发送第二监听组合指示信息，该第二监听组合指示信息指示第二BWP的监听组合。第一监听组合指示信息所指示的可以为以下中的一项：第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合。第二监听组合指示信息所指示的可以为以下中的一项：第一监听组合、第二监听组合、第三监听组合、第四监听组合或者第五监听组合。可理解，尽管此处以两个BWP为例进行阐述，但是对于更多个BWP的情形也是适用的，例如可以针对每个BWP分别指示各自BWP的监听组合。相应地，第一候选监听行为表示在激活的下行BWP上根据配置的搜索空间集监听PDCCH，第二候选监听行为表示在激活的下行BWP上在预设时间段内停止监听PDCCH，第三候选监听行为表示在激活的下行BWP上根据第一搜索空间集组中的搜索空间集监听PDCCH，第四候选监听行为表示在激活的下行BWP上根据第二搜索空间集组中的搜索空间集监听PDCCH，第五候选监听行为表示在激活的下行BWP上根据第三搜索空间集组中的搜索空间集监听PDCCH。
在终端设备410被配置有多个BWP的情况下，可以为不同的BWP分别配置监听组合，并且可理解不同的BWP所配置的监听组合可以相同也可以不同。举例而言，网络设备420可以为属于同一小区的多个BWP配置相同的监听组合。
可选地，在本公开的一些实施例中，第一监听组合指示信息可以指示第一小区的监听组 合。并且网络设备420还可以向终端设备410发送第三监听组合指示信息，该第三监听组合指示信息指示第二小区的监听组合。在终端设备410被配置有多个小区的情况下，可以为不同的小区分别配置监听组合，并且可理解不同的小区所配置的监听组合可以相同也可以不同。举例而言，网络设备420可以为属于同一小区组的多个小区配置相同的监听组合。
可选地，在本公开的一些实施例中，第一监听组合指示信息可以指示第一小区组的监听组合。并且网络设备420还可以向终端设备410发送第四监听组合指示信息，该第四监听组合指示信息指示第二小区组的监听组合。在终端设备410被配置有多个小区组的情况下，可以为不同的小区组分别配置监听组合，并且可理解不同的小区组所配置的监听组合可以相同也可以不同。
如图5所示，附加地或可选地，终端设备410可以向网络设备420发送502支持的监听组合信息。
具体地，该支持的监听组合信息可以指示终端设备410所支持的监听组合，其中终端设备410所支持的监听组合可以包括第一监听组合、第二监听组合、第三监听组合、第四监听组合和第五监听组合中的至少一种监听组合。并且，相应地，网络设备420所发送的第一监听组合指示信息所指示的监听组合中的候选监听行为是终端设备410所支持的监听组合中的候选监听行为的子集或全集。支持的监听组合信息可以被包括在UE能力信息中或者被包括在UE辅助信息中。在另一示例中，终端设备410所支持的监听组合可以包括第一监听组合、第二监听组合、第四监听组合和第五监听组合中的至少一种监听组合。
在一些实施例中，可以通过UE能力信息或UE辅助信息中的第一参数来指示终端设备410所支持的监听组合。举例而言，第一参数可以为支持的PDCCH监听适应(supportedPdcchMonitoringAdaptation)，例如，
Figure PCTCN2022118774-appb-000005
“ENUMERATED”表示枚举。“Beh 1and1A”表示包括第一候选监听行为和第二候选监听行为的第一监听组合。“Beh 1Aand2and2A”表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。“Beh 1Aand2and2Aand2B”表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。“Beh 2and2A”表示包括第三候选监听行为和第四候选监听行为的第四监听组合。“Beh 2and2Aand2B”表示包括第三候选监听行为、第四候选监听行为和第五候选监听行为的第五监听组合。
在一些实施例中，UE能力信息或UE辅助信息可以直接通过列举的形式来指示终端设备410所支持的监听组合，例如可以通过{参数1，参数2，…，参数N}的形式来配置，每一个参数对应一种候选监听行为。
具体而言，可以通过{Beh 1，Beh 1A}表示包括第一候选监听行为和第二候选监听行为的第一监听组合。通过{Beh 1A，Beh 2，Beh 2A}表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。通过{Beh 1A，Beh 2，Beh 2A，Beh 2B}表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。通过{Beh 2，Beh 2A}表示包括第三候选监听行为和第四候选监听行为的第四监听组合。通过{Beh 2，Beh 2A，Beh 2B}表示包括第三候选监听行为、第四候选监听行为和第五候选监 听行为的第五监听组合。
在一些实施例中，可以通过UE能力信息或UE辅助信息中的第二参数和第三参数的结合来指示终端设备410所支持的监听组合。举例而言，第二参数可以为支持的PDCCH监听适应(supportedPdcchMonitoringAdaptation)，第三参数可以为支持的搜索空间集组的数量(supportedNrofSearchSpaceSetGroup)。例如，
Figure PCTCN2022118774-appb-000006
“ENUMERATED”表示枚举，“INTEGER”表示整数。
具体而言，supportedPdcchMonitoringAdaptation指示“PdcchSkipping”表示包括第一候选监听行为和第二候选监听行为的第一监听组合。
具体而言，supportedPdcchMonitoringAdaptation指示“PdcchSkippingAndSearchSpaceSetGroupSwitching”且supportedNrofSearchSpaceSetGroup指示“2”表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。可选的，supportedPdcchMonitoringAdaptation指示“PdcchSkippingAndSearchSpaceSetGroupSwitching”表示包括第二候选监听行为、第三候选监听行为和第四候选监听行为的第二监听组合。
具体而言，supportedPdcchMonitoringAdaptation指示“PdcchSkippingAndSearchSpaceSetGroupSwitching”且supportedNrofSearchSpaceSetGroup指示“3”表示包括第二候选监听行为、第三候选监听行为、第四候选监听行为和第五候选监听行为的第三监听组合。
具体而言，supportedPdcchMonitoringAdaptation指示“SearchSpaceSetGroupSwitching”且supportedNrofSearchSpaceSetGroup指示“2”表示包括第三候选监听行为和第四候选监听行为的第四监听组合。
具体而言，supportedPdcchMonitoringAdaptation指示“SearchSpaceSetGroupSwitching”且supportedNrofSearchSpaceSetGroup指示“3”表示包括第三候选监听行为、第四候选监听行为和第五候选监听行为的第五监听组合。
可理解，网络设备420可以基于来自终端设备410的支持的监听组合信息，确定第一监听组合指示信息。并且随后，网络设备420可以将第一监听组合指示信息通过RRC信令发送到终端设备410。举例而言，可以从支持的监听组合信息所指示的监听组合中选择其中一种监听组合，并通过第一监听组合指示信息来指示所选择的监听组合。
在过程500中，网络设备420向终端设备410发送520DCI。
具体而言，终端设备410可以根据搜索空间集的配置信息确定PDCCH监听时机，进而可以在所确定的PDCCH监听时机上监听PDCCH。在某个PDCCH监听时机，终端设备410监听到来自网络设备420的DCI，该DCI被承载在PDCCH上。
该DCI可以用于指示终端设备410的监听行为，并且该指示的监听行为属于第一监听组 合指示信息中所包括的至少两种候选监听行为中的一种。
在过程500中，终端设备410可以基于第一监听组合指示信息和DCI，执行530PDCCH的监听行为。
附加地或可选地，终端设备410可以基于第一监听组合指示信息和DCI，从至少两个候选监听行为中确定522监听行为。
第一监听组合指示信息所指示的监听组合包括至少两个候选监听行为。可以基于DCI的具体值，从至少两个候选监听行为中选择与DCI的值对应的候选监听行为。
本公开的实施例中，DCI可以具有预定数量的比特，例如该预定数量的比特可以为1比特、2比特或更多比特。以该预定数量的比特是2比特为例，DCI可以具有四个不同的值：00、01、10和11。可理解，2比特可以是DCI中连续的两个比特，例如，同一个字段中的两个比特，或者可以是被间隔开的两个独立比特，例如，两个独立字段中分别有1比特，那么四个不同的值可以理解是由两个间隔开的独立比特所表示的值。
在一些实施例中，可以通过如下的表2所示的示例，来确定监听行为。例如，当第一监听组合指示信息指示第二监听组合且DCI为第一值时，确定监听行为为第二候选监听行为。当第一监听组合指示信息指示第五监听组合且DCI为第二值时，确定监听行为为第四候选监听行为。可选的，当第一监听组合指示信息指示第一监听组合，DCI为第二值、第三值或第四值的任一值，确定监听行为为第一候选监听行为。表2中示出的第一值、第二值、第三值和第四值互不相等。作为一例，第一值为00，第二值为01，第三值为10，第四值为11。但是本领域技术人员可理解，这仅是一个示例，其他的各种不同的示例可以在此基础上得到，依然属于本公开的保护范围。
表2
Figure PCTCN2022118774-appb-000007
应注意的是，表2示出的仅是本公开的一个示例。作为其他的示例，例如当第一监听组合指示信息指示第一监听组合时，可以通过DCI为第一值来指示第二候选监听行为，通过DCI为第二值来指示第一候选监听行为。或者，可以通过DCI为第二值来指示第二候选监听行为，通过DCI为第一值来指示第一候选监听行为。或者，可以通过DCI为第三值来指示第 二候选监听行为，通过DCI为第四值来指示第一候选监听行为。等等。这里不再一一罗列。
在另一些实施例中，在所确定的监听行为是第二候选监听行为时，可以使用固定的预设时间段(即被跳过的时间段)，或者可以使用多个不同的预定时间段。作为一例，如下表3所示。
表3
Figure PCTCN2022118774-appb-000008
应注意，在表3中仅示出了第一监听组合指示信息所指示的是第一监听组合或第二监听组合的情形，对于其他的情形可以参照表2，并且可理解，表3仅是示意，可以在表3的基础上进行各种变型以得到其他的实施例。
在另一些实施例中，可以通过DCI的值与该RRC信令中的至少两种候选监听行为的位置或索引的一一对应关系来确定监听行为。在一些实施例中，RRC信令可以通过列举的形式来配置至少两种候选监听行为。例如，RRC信令配置的至少两种候选监听行为为{Beh 1A，Beh 2，Beh 2A}时，DCI为第一值对应第一个索引的候选监听行为，即第二候选监听行为Beh 1A；DCI为第二值对应第二个索引的候选监听行为，即第三候选监听行为Beh 2；DCI为第三值对应第三个索引的候选监听行为，即第四候选监听行为Beh 2A。作为一例，可以通过DCI的值与该RRC信令中至少两种候选监听行为的位置或索引的一对多的对应关系来确定监听行为。例如，RRC信令配置的至少两种候选监听行为为{Beh 1A，Beh 2，Beh 2A}时，DCI为第一值对应第一个索引的候选监听行为，即第二候选监听行为Beh 1A，且使用第一预设时间段；DCI为第二值对应第一个索引的候选监听行为，即第二候选监听行为Beh 1A，且使用第二预设时间段。DCI为第三值对应第二个索引的候选监听行为，即第三候选监听行为Beh 2；DCI为第四值对应第三个索引的候选监听行为，即第四候选监听行为Beh 2A。
可理解的是，终端设备410所确定的监听行为可以用于类型3公共搜索空间集和终端设备专用搜索空间集。举例而言，假设监听行为是第二候选监听行为，那么可以针对类型3公共搜索空间集和终端设备专用搜索空间集，在预设时间段内停止监听，在该预设时间段之后再监听PDCCH。对于其他类型的公共搜索空间集，例如，类型0、类型0A、类型1、类型2公共搜索空间集，终端设备410可以跳过或不跳过C-RNTI、MCS-C-RNTI或CS-RNTI加扰的DCI的PDCCH监听，本公开的实施例不限定。对于类型0、类型0A、类型1、类型2公共搜索空间集，终端设备是否监听SI-RNTI、RA-RNTI、TC-RNTI或P-RNTI加扰的DCI的PDCCH，本公开的实施例不限定。
在终端设备410被配置有多个BWP，为不同的BWP分别配置监听组合的情况下，DCI 还可以进一步指示BWP标识(Identifier，ID)，终端设备410可以基于BWP ID对应的BWP的监听组合和上述实施例确定监听行为。
如此，本公开的实施例中，网络设备可以向终端设备配置监听组合，进而终端设备可以基于所配置的监听组合和来自网络设备的DCI来确定监听行为，终端设备通过执行该监听行为，能够减少对PDCCH的不必要监听，从而极大地降低了功耗。并且，通过本公开实施例中的监听组合的配置方式，实现了对于多种监听行为的合理组合，降低终端设备的实现复杂度。
应理解，在本公开的实施例中，“第一”，“第二”，“第三”等只是为了表示多个对象可能是不同的，但是同时不排除两个对象之间是相同的。“第一”，“第二”，“第三”等不应当解释为对本公开实施例的任何限制。
还应理解，本公开的实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便，不应构成特别的限定，各种方式、类别、情况以及实施例中的特征在符合逻辑的情况下，可以相互结合。
还应理解，上述内容只是为了帮助本领域技术人员更好地理解本公开的实施例，而不是要限制本公开的实施例的范围。本领域技术人员根据上述内容，可以进行各种修改或变化或组合等。这样的修改、变化或组合后的方案也在本公开的实施例的范围内。
还应理解，上述内容的描述着重于强调各个实施例之前的不同之处，相同或相似之处可以互相参考或借鉴，为了简洁，这里不再赘述。
