具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、先进的长期演进(Advanced long term evolution，LTE-A)***、新无线(New Radio，NR)***、NR***的演进***、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)***、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)***、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信***或其他通信***等。
通常来说，传统的通信***支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信***将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信***。
可选地，本申请实施例中的通信***可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。
示例性的，本申请实施例应用的通信***100如图1所示。该通信***100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域 内的终端设备进行通信。可选地，该网络设备110可以是GSM***或CDMA***中的基站(Base Transceiver Station，BTS)，也可以是WCDMA***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信***100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信***(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位***(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
网络设备110可以为小区提供服务，终端设备120通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备110进行通信，该小区可以是网络设备110(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括例如城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信***100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该通信***100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/***中具有通信功能的设备可称为通信设备。以图1示出的通信***100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信***100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“***”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
在本申请的一些实施例中，所述通信***100可以为5G NR。5G NR可以在4G基础上进一步增大***带宽，以提供更大的数据传输速率，进而提升用户体验。例如，在5G NR中，对于6GHz以下频段，单载波支持的最大带宽可以为100MHz；对于6GHz以上频段，单载波支持的最大带宽可以为400MHz。
与LTE***相同，5G NR也可以支持CA技术。对于支持CA特性的终端设备，例如，网络设备可以为终端设备配置多个服务小区，终端设备可以同时在这多个服务小区上进行数据的发送和接收，从而提升数据传输速率。
从另一方面来看，对于一个大的载波带宽，比如100HMz，终端设备可以使用的带宽往往非常有限，如果让终端设备始终在整个带宽上进行检测和测量，对终端设备的功耗将会是极大的挑战，不利于终端设备的省电。因此，5G NR中引入了带宽部分(BandWidth Part，BWP)的概念，即终端设备可以在整个大带宽的载波内的一部分连续的带宽(即BWP)上进行数据收发。终端设备只在网络设备配置的这部分带宽内进行相关操作，从而可以起到降低终端设备的耗电量的效果。
对于终端设备的每个服务小区，网络设备可以通过无线资源控制(Radio Resource Control，RRC)配置信息为终端设备在这个服务小区上配置一个或者多个BWP。例如，可配置的最大BWP数目可以为4。在每个时刻，终端设备在这个服务小区上可以只有1个激活的下行(Downlink，DL)BWP和1个激活的上行(Uplink，UL)BWP，终端设备可以只在激活的BWP上进行数据收发。
进一步地，可以使用以下4种方式来实现BWP切换：
1.基于物理下行控制信道(Physical Downlink Control Channel，PDCCH)的BWP切换。
2.基于RRC(重)配置的BWP切换。
3.基于定时器(timer)超时的BWP切换。
4.随机接入初始化引起的BWP切换。
终端设备通过接收网络设备发送的PDCCH来获知下行或上行调度信息，从而进一步完成业务数据的接收和发送。由于网络设备调度终端设备的时刻是不固定的，且没有相关信令告知终端设备网络设备是否给该终端设备发送了PDCCH，因此终端设备需要盲检PDCCH。
在现在的5G NR标准化过程中，从终端设备省电的角度出发，考虑在版本Rel-16中引入PDCCH跳过(skipping)机制，即网络可以通过发送动态信令指示终端设备跳过一段时间的PDCCH监听。
对于CA场景，如何控制终端设备在多个服务小区上的PDCCH skipping，目前还没有明确的规定。鉴于此，本申请实施例提出了一种监听控制信道的方法，可以在CA场景下实现终端设备在多个服务小区上的PDCCH skipping，从而可以动态地降低终端设备的耗电量。
图2是根据本申请实施例的监听控制信道的方法200的示意性流程图。图2所述的方法可以由终端设备和网络设备执行，该终端设备例如可以为图1中所示的终端设备120，该网络设备例如可以为图1中所示的网络设备110。如图2所示，该方法200可以包括以下内容中的至少部分内容。
在210中，在PDCCH搜索空间内，网络设备在多个服务小区中的至少一个服务小区上发送第一PDCCH，其中，所述第一PDCCH用于指示终端设备不监听PDCCH(PDCCH skipping)。
在220中，在PDCCH搜索空间内，终端设备在多个服务小区中的至少一个服务小区上接收第一PDCCH。
在230中，终端设备根据第一PDCCH，进行PDCCH skipping。
其中，第一PDCCH的数量可以是多个，也可以是一个，本申请对此不作具体限定。 比如，当网络设备在终端设备的4个服务小区上分别发送第一PDCCH时，第一PDCCH的数量为4。再比如，当网络设备在终端设备的1个服务小区上发送第一PDCCH时，第一PDCCH的数量为1。
上述内容提到的多个服务小区可以包括一个主服务小区(Primary Cell，PCell)，以及一个或者多个辅服务小区(Secondary Cell，SCell)。终端设备可以同时在PCell和激活的一个或者多个SCell上进行数据的发送和接收，从而提升数据传输速率。
其中，SCell有激活和非激活两种状态，当SCell处于激活状态时，终端设备可以在该SCell上进行数据的发送和接收。对于网络设备为终端设备配置的SCell，其初始状态为非激活状态。可以通过以下两种方式来实现SCell的激活/去激活：
1、通过媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)指示SCell激活/去激活。
2、基于timer超时的SCell去激活。
在本申请实施例中，PDCCH搜索空间可以理解为终端设备需要盲检的PDCCH资源集合。如此，可以限制终端设备盲检PDCCH的集合，从而降低终端设备盲检PDCCH的复杂度。
网络设备可以为终端设备的每个BWP配置一个或者多个PDCCH搜索空间。终端设备可以只在当前激活的BWP对应的PDCCH搜索空间上监听PDCCH，从而完成数据的收发。
可选地，网络设备可以通过配置信息将PDCCH搜索空间配置给终端设备。例如，网络设备可以向终端设备发送RRC配置信息，该RRC配置信息包括PDCCH搜索空间。
可选地，RRC配置信息还可以包括但不限于以下中的至少一项：
(a)Scell的配置参数。其中，Scell的配置参数可以包括但不限于以下中的至少一个：Scell的频点和物理小区标识(Physical Cell Identity，PCI)、Scell的标识、Scell的索引(Index)；
(b)多个服务小区中的每个服务小区的至少一个DL BWP；
(c)每个服务小区DL BWP上的至少一个PDCCH搜索空间；
(d)每个服务小区可支持的至少一个PDCCH skipping的时间长度(duration)，即PDCCH skipping duration集合。
可选地，在本申请实施例中，终端设备进行PDCCH skipping的时间长度(duration)(为了描述方便，称为第一PDCCH skipping duration值)可以是协议规定预设在终端设备上的。
或者，第一PDCCH skipping duration值可以是终端设备和网络设备提前协商好，预设在终端设备上的。
或者，第一PDCCH除了指示终端设备的调度信息之外，还可以用于指示第一PDCCH skipping duration值。其中，第一PDCCH指示第一PDCCH skipping duration值可以包括两种情况。
情况1
网络设备可以通过RRC配置信息为每个服务小区预配置PDCCH skipping duration集合，该PDCCH skipping duration集合包括第一PDCCH skipping duration值。在该情况中，第一PDCCH可以用于指示第一PDCCH skipping duration值在PDCCH skipping duration集合中的索引或者编号。例如，对于PCell，网络设备为终端设备预配置的PDCCH skipping duration集合包括2时隙(slots)、4slots、8slots和16slots，该4个PDCCH skipping duration值的索引分别为0、1、2和3，若第一PDCCH skipping duration值为4slots，则第一PDCCH可以指示索引1。
或者，第一PDDCH可以用于指示PDCCH skipping duration集合中的第一PDCCH skipping duration值。例如，对于PCell，网络设备为终端设备预配置的PDCCH skipping  duration集合包括2slots、4slots、8slots和16slots，若第一PDCCH skipping duration值为4slots，则第一PDCCH可以指示4slots。
情况2
网络设备不预配置PDCCH skipping duration集合，第一PDCCH中携带第一PDCCH skipping duration值的指示。
在本申请实施例中，终端设备进行PDCCH skipping的起始时刻可以有多种可能，作为一种示例，参考图3，终端设备进行PDCCH skipping的起始时刻可以为终端设备接收到第一PDCCH的下一个时间单元的起始时刻，即终端设备在完成第一PDCCH接收的下一个时间单元开始不监听PDCCH。
其中，时间单元可以为子帧、时隙、时域符号(symbol)或短传输时间间隔(Short Transmission Timing Interval,sTTI)等。
作为另一种示例，终端设备进行PDCCH skipping的起始时刻可以是第一PDCCH调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输或者物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输成功的下一个时间单元的起始时刻，即终端设备在完成第一PDCCH调度的上行传输后停止监听PDCCH。
若第一PDCCH调度终端设备的下行数据传输，如图4所示，终端设备进行PDCCH skipping的起始时刻可以为终端设备发送完上行控制信息(Uplink Control Information，UCI)的下一个时间单元的起始时刻，其中，UCI是针对物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的反馈。也就是说，如果终端设备接收到的是指示终端设备下行调度的第一PDCCH，则终端设备可以在完成PDSCH接收和针对该PDSCH的UCI反馈的下一个时间单元开始不监听PDCCH。
若第一PDCCH调度终端设备的上行数据传输，如图5所示，终端设备进行PDCCH skipping的起始时刻可以为终端设备发送完PUSCH的下一个时间单元的起始时刻。也就是说，如果终端设备接收到的是指示该终端设备上行调度的第一PDCCH，则终端设备在完成PUSCH发送的下一个时间单元开始不监听PDCCH。
为了描述方便，本申请实施例将终端设备进行PDCCH skipping的服务小区称为第一服务小区，其中，第一服务小区包括多个服务小区中的至少一个服务小区。
下面将详细描述网络设备在多个服务小区中的至少一个服务小区上发送第一PDCCH的两种实现方式。
在一种实现方式中，网络设备可以在多个服务小区中的每个服务小区上分别发送一个第一PDCCH，相应地，终端设备可以在多个服务小区中的每个服务小区上分别接收一个第一PDCCH。此时，第一PDCCH的数量与多个服务小区的数量相等。
在该实现方式中，终端设备在每个服务小区上接收到的第一PDCCH可以指示终端设备在该服务小区上进行PDCCH skipping。此时，第一服务小区为终端设备所有的服务小区。例如，对于配置了PCell、SCell 1和SCell 2的终端设备，网络设备可以针对终端设备的每个服务小区，即PCell、SCell 1和SCell 2分别发送第一PDCCH，终端设备在PCell上接收到的第一PDCCH可以指示终端设备在PCell上进行PDCCH skipping，终端设备在SCell 1上接收到的第一PDCCH可以指示终端设备在SCell 1上进行PDCCH skipping，终端设备在SCell 2上接收到的第一PDCCH可以指示终端设备在SCell 2上进行PDCCH skipping。此时，终端设备可以根据每个服务小区上接收的一个第一PDCCH，进行PDCCH skipping。
或者，终端设备在每个服务小区上接收到的第一PDCCH可以指示终端设备在所有的服务小区上进行PDCCH skipping。例如，对于配置了PCell、SCell 1和SCell 2的终端设备，网络设备可以针对PCell、SCell 1和SCell 2分别发送第一PDCCH，终端设备在PCell、SCell 1和SCell 2上接收到的第一PDCCH都可以用于指示终端设备在PCell、SCell1和SCell 2上进行PDCCH skipping。
再或者，终端设备在每个服务小区上接收到的第一PDCCH可以指示终端设备在多个服务小区中的部分服务小区上进行PDCCH skipping。比如，对于配置了PCell、SCell 1和SCell 2的终端设备，网络设备针对终端设备的每个服务小区分别发送第一PDCCH，终端设备在PCell上接收到的第一PDCCH指示终端设备在SCell 1和SCell 2上进行PDCCH skipping，终端设备在SCell 1上接收到的第一PDCCH指示终端设备在SCell 1上进行PDCCH skipping，终端设备在SCell 2上接收到的第一PDCCH指示终端设备在SCell 2上进行PDCCH skipping。此时，第一服务小区为SCell 1和SCell 2。
在另一种实现方式中，网络设备可以在多个服务小区中的部分服务小区上发送第一PDCCH，相应地，终端设备可以在多个服务小区中的部分服务小区上接收第一PDCCH。
作为一种示例，若第一服务小区包括N个服务小区，且该N个服务小区为多个服务小区中的部分服务小区，N为大于1的正整数，则网络设备可以在第一服务小区上分别发送第一PDCCH。例如，对于同时配置了PCell、SCell 1和SCell 2的终端设备，第一服务小区为PCell和SCell 1，则网络设备可以在PCell和SCell 1上分别向终端设备发送第一PDCCH，相应地，终端设备可以在PCell和SCell 1上分别接收第一PDCCH。
作为另一种示例，终端设备可以在多个服务小区中的一个服务小区上接收第一PDCCH。可选地，所述一个服务小区可以是PCell。之后，终端设备可以根据第一PDCCH，在第一服务小区上进行PDCCH skipping。例如，对于同时配置了PCell、SCell 1和SCell2的终端设备，第一服务小区为PCell、SCell 1和SCell 2，终端设备在PCell上接收第一PDCCH，然后终端设备可以根据第一PDCCH的指示在PCell、SCell 1和SCell 2上进行PDCCH skipping。此时，第一PDCCH的数量为1。
可选地，在本申请实施例中，若第一服务小区包括N个服务小区，终端设备在N个服务小区上的第一PDCCH skipping duration值可以相同。
可选地，在本申请实施例中，若第一服务小区包括N个服务小区，终端设备在N个服务小区中的至少两个服务小区上的第一PDCCH skipping duration值可以不同。例如，对于同时配置了PCell、SCell 1和SCell 2的终端设备，终端设备在PCell上接收第一PDCCH，然后终端设备可以根据第一PDCCH的指示在PCell、SCell 1和SCell 2上进行PDCCH skipping，其中，终端设备在PCell和SCell 1上的第一PDCCH skipping duration值为8slots，终端设备在SCell 2上的第一PDCCH skipping duration值为16slots。
可选地，第一PDCCH还可以用于指示第一服务小区，即第一PDCCH还可以指示终端设备在哪一个或者哪几个服务小区上进行PDCCH skipping。比如，第一PDCCH指示第一服务小区为PCell。
或者，第一PDCCH可以不指示第一服务小区，第一服务小区可以是协议规定的。此时，第一服务小区可以是该多个服务小区，或者，第一服务小区是PCell，或者，第一服务小区是所有的SCell，或者，第一服务小区是SCell中的部分服务小区。
可选地，对于需要PDCCH skipping的服务小区，即第一服务小区，终端设备在第一服务小区中的各个服务小区上PDCCH skipping的起始时刻可以相同，也可以不同，本申请实施例对此不作具体限定。
下面将结合3个具体实施例详细描述本申请实施例的技术方案。
实施例一
对于同时配置了多个服务小区的终端设备，网络设备可以通过在终端设备的每个服务小区上分别发送第一PDCCH，以指示终端设备在每个服务小区上进行PDCCH skipping。
具体而言，如图6所示，步骤1：终端设备接收网络设备发送的RRC配置信息，其中，RRC配置信息包括：
(a)SCell配置：2个SCell，分别是SCell 1和SCell 2；
(b)各个服务小区的DL BWP配置：对于PCell和每个SCell，各配置1个DL BWP；
(c)各个服务小区DL BWP上的PDCCH搜索空间配置：对于PCell和每个SCell上的DL BWP，各配置一个PDCCH搜索空间。其中，PCell和SCell 1上的DL BWP的PDCCH搜索空间对应的PDCCH监听周期都为2slots，SCell 2上的DL BWP的PDCCH搜索空间对应的PDCCH监听周期为4slots；
(d)各个服务小区的PDCCH skipping duration配置：对于每个服务小区，各配置4个PDCCH skipping duration值。对于PCell，配置的4个PDCCH skipping duration值分别为2slots、4slots、8slots和16slots；对于SCell 1和SCell 2，配置的4个PDCCH skipping duration值分别为4slots、8slots、16slots和32slots。
步骤2：终端设备在PCell、SCell 1和SCell 2的PDCCH搜索空间上监听PDCCH，如果终端设备接收到的第一PDCCH中包含了PDCCH skipping指示信息，则终端设备可以根据接收到的第一PDCCH指示在随后的一段时间内不监听PDCCH。
例如，终端设备在PCell上监听PDCCH，当终端设备在PCell上接收到的第一PDCCH指示终端设备PDCCH skipping的时长为8slots，则终端设备在随后的8slots时间内在PCell上不监听PDCCH。随后，终端设备又在PCell上接收到第一PDCCH，该第一PDCCH指示终端设备PDCCH skipping的时长为4slots，则终端设备在随后的4slots时间内在PCell上不监听PDCCH。后来，终端设备又在PCell上接收到的第一PDCCH指示终端设备PDCCH skipping的时长为16slots,则终端设备在随后的16slots时间内在PCell上不监听PDCCH。
类似地，终端设备在SCell 1监听PDCCH，当终端设备在SCell 1上接收到的第一PDCCH指示终端设备PDCCH skipping的时长为4slots，则终端设备在随后的4slots时间内在SCell 1上不监听PDCCH。随后，终端设备又在SCell 1上接收到的第一PDCCH指示终端设备PDCCH skipping的时长为16slots，则终端设备在随后的16slots时间内在SCell 1上不监听PDCCH。
终端设备在SCell 2上监听PDCCH，当终端设备在SCell 2上接收到第一PDCCH，该第一PDCCH指示终端设备PDCCH skipping的时长为8slots，则终端设备在随后的8slots时间内在SCell 2上不监听PDCCH。随后，终端设备又在SCell 2上接收到的第一PDCCH指示终端设备PDCCH skipping的时长为4slots，则终端设备在随后的4slots时间内在SCell 2上不监听PDCCH。后来，终端设备又在SCell 2上接收到的第一PDCCH指示终端设备PDCCH skipping的时长为16slots,则终端设备在随后的16slots时间内在SCell 2上不监听PDCCH。
实施例一的技术方案可以灵活地控制终端设备在各个服务小区上的PDCCH skipping，从而实施例一的技术方案节能增益较大。
实施例二
对于同时配置了多个服务小区的终端设备，网络设备在PCell上发送第一PDCCH，以指示终端设备在部分或者所有的服务小区上进行PDCCH skipping，其中，终端设备在所有的服务小区上的PDCCH skipping duration值相同。
具体而言，参考图7，步骤1：终端设备接收网络设备发送的RRC配置信息，其中，RRC配置信息包括：
(a)SCell配置：2个SCell，分别是SCell 1和SCell 2；
(b)各个服务小区的DL BWP配置：对于PCell和每个SCell，各配置1个DL BWP；
(c)各个服务小区DL BWP上的PDCCH搜索空间配置：对于PCell和每个SCell上的DL BWP，各配置一个PDCCH搜索空间。其中，PCell和SCell 1上的DL BWP的PDCCH搜索空间对应的PDCCH监听周期都为2slots，SCell 2上的DL BWP的PDCCH搜索空间对应的PDCCH监听周期为4slots；
(d)PDCCH skipping duration配置：为终端设备配置4个PDCCH skipping duration值，分别为4slots、8slots、16slots和32slots。
步骤2：终端设备在PCell的PDCCH搜索空间上监听PDCCH，如果终端设备接收的第一PDCCH中包含了PDCCH skipping指示信息，则终端设备可以根据接收到的第一PDCCH的指示，在随后的一段时间内在部分或者所有服务小区上都不监听PDCCH。
例如，终端设备在PCell上接收到第一PDCCH，该第一PDCCH指示终端设备PDCCH skipping的时长为8slots，则终端设备在随后的8slots时间内在PCell、SCell 1和SCell 2上都不监听PDCCH。随后，终端设备又在PCell上接收到指示终端设备PDCCH skipping的时长为4slots的第一PDCCH,则终端设备在随后的4slots时间内在PCell、SCell 1和SCell 2上都不监听PDCCH。之后，终端设备又在PCell上接收到指示终端设备PDCCH skipping的时长为16slots的第一PDCCH，则终端设备在随后的16slots时间内在PCell、SCell 1和SCell 2上都不监听PDCCH。
可以看到，实施例一中网络设备可以为终端设备的每个服务小区分别配置一套PDCCH skipping duration参数，而实施例二中网络设备可以只为终端设备配置一套PDCCH skipping duration参数。
实施例二的技术方案通过在PCell发送动态信令控制终端设备在部分或者所有服务小区上的PDCCH skipping，终端设备在所有第一服务小区上的PDCCH skipping duration相同，且PDCCH skipping duration可以动态调整，相对于实施例一的方案来说，信令开销较小。
实施例三
对于同时配置了多个服务小区的终端设备，网络设备可以通过在终端设备的PCell上发送第一PDCCH，以指示终端设备在部分或者所有服务小区上进行PDCCH skipping，且终端设备在各服务小区上的PDCCH skipping duration可以不同。
具体而言，参考图8，步骤1：终端设备接收网络设备发送的RRC配置信息，其中，RRC配置信息包括：
(a)SCell配置：2个SCell，分别是SCell 1和SCell 2；
(b)各个服务小区的DL BWP配置：对于PCell和每个SCell，各配置1个DL BWP；
(c)各个服务小区DL BWP上的PDCCH搜索空间配置：对于PCell和每个SCell上的DL BWP，各配置一个PDCCH搜索空间。其中，PCell和SCell 1上的DL BWP的PDCCH搜索空间对应的PDCCH监听周期都为2slots，SCell 2上的DL BWP的PDCCH搜索空间对应的PDCCH监听周期为4slots；
(d)各个服务小区的PDCCH skipping duration配置：PCell和SCell 1上的PDCCH skipping duration值为16slots，SCell 2上的PDCCH skipping duration值为8slots。
步骤2：终端设备在PCell的PDCCH搜索空间上监听PDCCH，如果终端设备接收的第一PDCCH中包含了PDCCH skipping指示信息，则终端设备可以根据接收到的第一PDCCH指示在随后的一段时间内在部分或所有服务小区上都不监听PDCCH。
例如，终端设备在PCell上接收到第一PDCCH，该第一PDCCH指示终端设备在SCell1和SCell 2上进行PDCCH skipping，则终端设备在随后的16slots时间内在SCell 1上不监听PDCCH，同时终端设备在随后的8slots在SCell 2上也不监听PDCCH。随后，终端设备又在PCell上接收到第一PDCCH指示终端设备在所有服务小区上进行PDCCH skipping，则终端设备在随后的16slots时间内在PCell和SCell 1上不监听PDCCH，同时终端设备在随后的8slots在SCell 2上不监听PDCCH。
实施例三的技术方案，由于第一PDCCH可以不用于指示第一PDCCH skipping duration值，因此，实施例三的信令开销最小。
应理解，实施例一、实施例二和实施例三中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
还应理解，用于指示终端设备进行PDCCH skipping的信令除了可以是PDCCH之外，还可以是其他的动态信令，如MAC CE等。
本申请实施例，对于同时配置多个服务小区的终端设备，网络设备可以向终端设备发送用于指示终端设备进行PDCCH skipping的PDCCH，终端设备接收到该PDCCH后可以在一段时间内不监听PDCCH，从而可以动态地支持终端设备节电，即可以降低终端设备的耗电量。
上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于上述实施方式中的具体细节，在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，这些简单变型均属于本申请的保护范围。
例如，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。
又例如，本申请的各种不同的实施方式之间也可以进行任意组合，只要其不违背本申请的思想，其同样应当视为本申请所公开的内容。
应理解，在本申请的各种方法实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
上文中详细描述了根据本申请实施例的通信方法，下面将结合图9至图11，描述根据本申请实施例的通信装置，方法实施例所描述的技术特征适用于以下装置实施例。
