图1示出本申请实施例可应用的一种无线通信系统的结构示意图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、游戏机、可穿戴式设备(wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B(evolved NodeB，eNB)、接入点、 基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
为便于理解，在此对本申请中提及的类型为0的公共搜索空间集合Type0 CSS set(即Type0-PDCCH CSS set)、类型为0A的公共搜索空间集合Type0A CSS set(即Type0A-PDCCH CSS set)、类型为1的公共搜索空间集合Type1 CSS set(即Type1-PDCCH CSS set)、类型为2的公共搜索空间集合Type2 CSS set(即Type1-PDCCH CSS set)进行简单介绍。
(1)Type0-PDCCH CSS set，由主信息块(Master Information Block，MIB)中的“pdcchConfigSIB1”或PDCCH-ConfigCommon中的“searchSpaceSIB1”或PDCCH-ConfigCommon中的“searchSpaceZero”配置，用于检测由系统信息-无线网络临时标识(System Information-Radio Network Temporary Identifier，SI-RNTI)(用于SIB 1)加扰的DCI format，该DCI在主小区组(Master cell group，MCG)中的主小区上发送。
(2)Type0A-PDCCH CSS set，由PDCCH-ConfigCommon中的“searchSpaceOtherSystemInformation”配置，用于检测由SI-RNTI(用于其他SI)加扰的DCI format，且该DCI在MCG中的主小区上发送。
(3)Type1-PDCCH CSS set，由PDCCH-ConfigCommon中“ra- SearchSpace”配置，用于检测由随机接入(Random Access，RA)-RNTI(用于RAR)或临时小区(Temporary Cell，TC)-RNTI(用于Msg4)或消息(Message，Msg)B-RNTI加扰的DCI format，该DCI在主小区中发送。
(4)Type2-PDCCH CSS set，由PDCCH-ConfigCommon中的“pagingSearchSpace”配置，用于检测由寻呼(Paging，P)-RNTI(用于寻呼)加扰的DCI format，该DCI在MCG中的主小区上发送。
此外，在上述Type 0 CSS set，Type 0A CSS set，Type 1 CSS set，Type 2 CSS set上，网络侧可以发送与调度数据相关的RNTI(例如，小区C-RNTI)加扰的DCI，因此终端除了需要在Type 0 CSS set，Type 0A CSS set，Type 1 CSS set，Type 2 CSS set上监听上述由P-RNTI、SI-RNTI等加扰的DCI，还需要监听调度数据相关RNTI加扰的DCI。
如图2所示，为本申请一示例性实施例提供的PDCCH监听方法200的流程示意图，该方法200可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，终端获取第一配置信息。
其中，所述第一配置信息用于配置第一CSS set与第一搜索空间组之间的关联关系(linkage)，如，所述第一配置信息中可以包括第一CSS set所关联到的第一搜索空间组的编号或索引信息、第一CSS set与第一搜索空间组是否存在关联关系、第一CSS set的类型信息、第一CSS set能否与第一搜索空间组关联的信息、第一CSS set可以关联哪些第一搜索空间组的信息、第一CSS set与第一搜索空间组进行关联的时间信息、是否开启或激活第一CSS set与第一搜索空间组之间的关联关系等，在此不作限制。
可以理解，本申请中所述的第一CSS set可以理解为任意公共搜索空间集合或公共搜索空间，而第一搜索空间组可以理解为是由网络侧配置 或协议规定或高层信令配置的一个搜索空间组，以通过是否激活该搜索空间组或是否切换到该搜索空间组上工作，来确定是否在与搜索空间组关联的CSS set监听PDCCH。可选地，本申请中所述的第一搜索空间组可以为空，也可以包括至少一个搜索空间集合或搜索空间。
本实施例中，所述第一配置信息可以通过网络侧配置或协议约定或高层信令(如无线资源控制(Radio Resource Control，RRC)信令)配置，例如，可通过协议约定Type 0 CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set中至少之一可以关联到第一搜索空间组等。
当然，本实施例通过第一配置信息，配置第一CSS set与第一搜索空间组之间的关联关系的目的是：终端可以根据第一搜索空间组是否被激活或当前是否切换到第一搜索空间组上工作，来确定PDCCH的监听(monitoring)行为，如是否需要在与第一搜索空间组关联的第一CSS set上监听PDCCH或特定DCI等，由此来避免由于第一CSS set不属于任意一个搜索空间组，而导致的无法通过搜索空间组的切换而跳过PDCCH监听的问题，使得终端无需一直在第一CSS set上监听PDCCH，有效的降低了终端的功耗，达到省电的目的。
在此情况下，本实施例中给出的所述第一配置信息可以包括以下(1)至(2)中至少一项。
(1)所述第一CSS set所关联的第一搜索空间组的编号信息。
其中，所述编号信息也可以理解索引信息或标识信息等。本实施例中，所述第一搜索空间组的编号信息可以为0、1、2等，用来分别代表搜索空间组#0、搜索空间组#1、搜索空间组#2，在此不做限制。
(2)所述第一CSS set能否关联到所述第一搜索空间组的信息。其中，“能否”也可以理解为“是否可以”、“是否支持”等。
此外，对于(2)可以理解为：是否可以让第一CSS set关联到第一搜索空间组。
一种实现方式中，还可以通过网络侧配置或协议约定选取：(1)第 一CSS set可以关联到第一搜索空间组，或(2)第一CSS set不可以关联到第一搜索空间组中的任一项作为默认配置。例如，在网络侧未配置该参数(指的是所述第一CSS set能否关联到所述第一搜索空间组)时，也就是说该参数缺省时，默认配置为可以让类型(Type)0 CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set中至少一项关联到第一搜索空间组上，也就是，默认所述第一CSS set能够关联到第一搜索空间组。
在本实施例中，所述第一CSS set可以有多个，如所述第一CSS set包括类型(Type)为0的CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set中至少一项。相应的，所述第一搜索空间组也可以有多种，如搜索空间组#0、搜索空间组#1等。例如，所述搜索空间组#0关联着稀疏的PDCCH监听周期的搜索空间；搜索空间组#1关联着密集的PDCCH监听周期的搜索空间。
基于此，作为一种实现方式，上述第一CSS set中如果包括多个CSS set，那么上述多个CSS set中的每一个CSS set可以分别关联不同的搜索空间组或相同的一个搜索空间组，或者，上述多个CSS set中的每一个CSS set可以关联不同的搜索空间组或相同的多个搜索空间组。例如，第一CSS set中包括Type1 CSS set、Type2 CSS set，那么，Type1 CSS set关联搜索空间组0，Type2 CSS set关联搜索空间组1，或者，Type1 CSS set、Type2 CSS set关联搜索空间组0等。
S220，所述终端根据所述第一配置信息，确定在所述第一CSS set上的PDCCH监听行为。
其中，在所述第一CSS set上的PDCCH监听行为也可以理解为：在第一CSS set所对应的PDCCH监听时机(Monitoring Occasion，MO)上的PDCCH监听行为。
本实施例中，终端根据第一配置信息，确定在所述第一CSS set上的PDCCH监听行为，由此，能够解决终端需要一直在第一CSS set上监听 PDCCH的问题，降低了终端功耗。
如图3所示，为本申请一示例性实施例提供的PDCCH监听方法300的流程示意图，该方法可以但不限于由终端执行，具体可由安装于终端中的硬件/和/或软件执行。本实施例中，所述方法300至少可以包括如下步骤。
S310，终端获取第一配置信息。
其中，所述第一配置信息用于配置第一CSS set与第一搜索空间组之间的关联关系。
需要注意，S310的实现方式除了可参照方法实施例200中的相关描述之外，作为本实施例中的一种可能的实现方式，所述第一搜索空间组可以为非休眠搜索空间组；其中，所述非休眠搜索空间组是除休眠搜索空间组之外的其他搜索空间组，所述休眠搜索空间组不关联任何搜索空间，或，所述终端在所述休眠搜索空间组上不监听新传PDCCH。新传
PDCCH又可称为初传PDCCH，新传PDCCH是相对于重传PDCCH而言的，可以指多次PDCCH传输中的第一次传输。
换言之，所述非休眠搜索空间组可以关联一个或多个搜索空间，或终端可以在非休眠搜索空间组上监听新传PDCCH，例如，在本实施例中，所述非休眠搜索空间组可以为搜索空间组#1和/或搜索空间组#0。
S320，所述终端根据所述第一配置信息，确定在所述第一CSS set上的PDCCH监听行为。
需要注意，S320的实现方式除了可参照方法实施例200中的相关描述之外，根据所述第一配置信息的不同，所述终端在所述第一CSS set上的PDCCH监听行为不同，例如，在本实施例中，作为一种可能的实现方式，终端根据所述第一配置信息，确定在第一CSS set上的PDCCH监听行为的步骤，可以包括以下(1)至(6)中的至少一项。
(1)在所述第一CSS set关联到所述第一搜索空间组、且所述第一搜索空间组处于非激活状态(inactive)的情况下，在所述第一CSS set 上，所述终端不监听由第一RNTI加扰的DCI。
其中，所述第一RNTI可以包括小区(Cell，C)-RNTI、调制和编码方案(Modulation and coding scheme，MCS)-CRNTI、配置调度(Configured Scheduling，CS)-RNTI中的至少一项。
进一步的，在一种实现方式中，在所述第一CSS set关联到所述第一搜索空间组、且所述第一搜索空间组处于非激活状态的情况下，在所述第一CSS set上，所述终端不监听由第一RNTI加扰的DCI，但仍然需要监听由第二RNTI加扰的DCI。其中，所述第二RNTI可以包括SI-RNTI、RA-RNTI、MsgB-RNTI、TC-RNTI、P-RNTI中的至少一项。
通过上述实现方式，能够减少由于终端在第一CSS set上监听由第一RNTI加扰的DCI(即与调度数据相关RNTI加扰的DCI)而导致的不必要的功率消耗，同时又不会跳过由第一RNTI加扰的DCI的PDCCH监听，也就是保证了寻呼消息、系统消息、随机接入的接收检测性能。
例如，假设协议约定Type 0 CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set可以关联到非休眠搜索空间组(即第一搜索空间组)。其中，网络侧配置Type 0 CSS set、Type 0A CSS set、Type 2 CSS set关联的搜索空间组号(SSS group ID，SSSG ID)为0；网络侧配置Type 1 CSS set关联的group ID为1。当SSSG 1(搜索空间组1)被激活时，也就是SSSG0未被激活时，终端在Type 0 CSS set、Type 0A CSS set、Type 2 CSS set所对应的PDCCH MO上不需要监听由C-RNTI、MCS-C-RNTI和CS-RNTI加扰的DCI format 1-0和0-0，而只需要在Type 0 CSS set、Type 0A CSS set、Type 2 CSS set所对应的各自的PDCCH MO上分别监听SI-RNTI加扰的DCI(对应Type 0 CSS set、Type 0A CSS set)和P-RNTI加扰的DCI(对应type 2 CSS set)即可。
此外，根据现有协议约定，当终端处于RRC连接态时，其可以在一个系统消息的修改周期(Modification Period)内的任何寻呼时机(paging occasion，PO)上至少监听一次SI-RNTI加扰的DCI，也就是终 端只需要监听一次SI-RNTI加扰的DCI来接收SI更新指示(update indication)即可。因此，通过本申请给出的PDCCH监听方法，当Type 0 CSS set、Type 0A CSS set、Type 2 CSS set关联到的SSSG0且SSSG0未被激活时，终端省去了监听由C-RNTI、MCS-C-RNTI和CS-RNTI加扰的DCI format 1-0和0-0而浪费的功耗，从而进一步实现节能。
(2)在所述第一CSS set关联到所述第一搜索空间组、且所述第一搜索空间组处于激活状态的情况下，在所述第一CSS set上，所述终端监听由第一RNTI和/或第二RNTI加扰的DCI。
可选的，所述第一RNTI可以包括C-RNTI、MCS-CRNTI、CS-RNTI中的至少一项；所述第二RNTI包括SI-RNTI、RA-RNTI、MsgB-RNTI、TC-RNTI、P-RNTI中的至少一项。
例如，假设协议约定Type 0 CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set可以关联到非休眠搜索空间组(即第一搜索空间组)。其中，网络侧配置Type 0 CSS set、Type 0A CSS set、Type 2 CSS set关联的搜索空间组号(SSS group ID，SSSG ID)为0；网络侧配置Type 1 CSS set关联的group ID为1。当SSSG 1(搜索空间组1)被激活时，也就是SSSG0未被激活时，终端在type1 CSS set所对应的PDCCH MO上监听由C-RNTI、MCS-C-RNTI和CS-RNTI加扰的DCI format 1-0和0-0，和/或，终端在type1 CSS set所对应的PDCCH MO上监听由RA-RNTI加扰的DCI。
(3)在所述第一CSS set关联到所述第一搜索空间组、且所述第一搜索空间组处于激活状态的情况下，在所述第一CSS set上，所述终端不监听由第一RNTI加扰的DCI。
其中，所述第一RNTI可以包括C-RNTI、MCS-CRNTI、CS-RNTI中的至少一项。
例如，假设协议约定Type 0 CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set可以关联到非休眠搜索空间组(即第一搜索空间 组)。其中，网络侧配置Type 0 CSS set、Type0A CSS set、Type 2 CSS set关联的搜索空间组号(SSS group ID，SSSG ID)为0；网络侧配置Type 1 CSS set关联的group ID为1。当SSSG 1(搜索空间组1)被激活时，也就是SSSG0未被激活时，终端在type1 CSS set所对应的PDCCH MO上不监听由C-RNTI、MCS-C-RNTI和CS-RNTI加扰的DCI format 1-0和0-0。
(4)在所述第一CSS set关联到所述第一搜索空间组、且所述第一搜索空间组处于非激活状态的情况下，在所述第一CSS set上，所述终端不监听PDCCH。
其中，终端不监听PDCCH可以理解为：终端不监听由任意RNTI加扰的DCI。
例如，假设协议约定Type 0 CSS set、Type0A CSS set、Type1 CSS set、Type2 CSS set可以关联到非休眠搜索空间组(即第一搜索空间组)。其中，网络侧配置Type 0 CSS set、Type0A CSS set、Type2 CSS set关联的搜索空间组号(SSS group ID，SSSG ID)为0；网络侧配置Type 1 CSS set关联的group ID为1。当SSSG0处于非激活状态，终端在Type 0 CSS set、Type0A CSS set、Type2 CSS set上不需要监听C-RNTI、MCS-C-RNTI和CS-RNTI等加扰的DCI format 1-0和0-0，也不需要监听P-RNTI和SI-RNTI加扰的DCI；也就是在该CSS set对应的PDCCH上不需要监听任何PDCCH，从而进一步实现节能。
(5)在所述第一CSS set不能与所述第一搜索空间组关联的情况下，在所述第一CSS set上，所述终端监听由第一RNTI和/或第二RNTI加扰的DCI。
其中，所述第一RNTI可以包括C-RNTI、MCS-CRNTI、CS-RNTI中的至少一项。所述第二RNTI包括SI-RNTI、RA-RNTI、MsgB-RNTI、TC-RNTI、P-RNTI中的至少一项。
例如，假设协议约定Type1 CSS set不能关联到非休眠搜索空间组 (即第一搜索空间组)，那么，终端在type1 CSS set所对应的PDCCH MO上监听由C-RNTI、MCS-C-RNTI、CS-RNTI加扰的DCI format 1-0和0-0，和/或，终端在Type1 CSS set所对应的PDCCH MO上监听由SI-RNTI、RA-RNTI、MsgB-RNTI、TC-RNTI、P-RNTI加扰的DCI。
(6)在所述第一CSS set不能与所述第一搜索空间组关联的情况下，在所述第一CSS set上，所述终端不监听由第一RNTI加扰的DCI。
其中，所述第一RNTI可以包括C-RNTI、MCS-CRNTI、CS-RNTI中的至少一项。
例如，假设协议约定Type1 CSS set不能关联到非休眠搜索空间组(即第一搜索空间组)，那么，终端在type1 CSS set所对应的PDCCH MO上，不监听由C-RNTI、MCS-C-RNTI、CS-RNTI加扰的DCIformat1-0和0-0。
需要说明的是，本实施例中，终端基于第一配置信息确定的PDCCH监听行为可以包括但不限于前述(1)至(6)中的一种或多种，在此不做限制。
另外，第一CSS set被高层信令配置用于监听其所对应的第二RNTI加扰的DCI。例如，Type 0 CSS set或Type 0A CSS set被高层信令配置用于监听SI-RNTI加扰的DCI；Type 1 CSS set被高层信令配置用于监听RA-RNTI或MsgB-RNTI或TC-RNTI加扰的DCI；Type 2 CSS set被高层信令配置用于监听P-RNTI加扰的DCI。
本实施例中终端根据第一配置信息，确定在第一CSS set上的PDCCH监听行为以及上述具体的步骤，可以实现避免由于终端在第一CSS set上监听由第一RNTI加扰的DCI而导致的不必要的功率消耗，并且在节省终端功耗的同时又不会影响寻呼消息、系统消息、随机接入的接收检测性能。
如图4所示，为本申请一示例性实施例提供的PDCCH监听方法400的流程示意图，该方法400可以但不限于由网络侧设备执行，具体可由 安装于网络侧设备中的硬件/和/或软件执行。本实施例中，所述方法400至少可以包括如下步骤。
