Description

物理下行控制信道的监听方法、装置及设备
相关申请的交叉引用
本申请主张在2019年4月30日在中国提交的中国专利申请号No.201910365516.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种物理下行控制信道的监听方法、装置及设备。
背景技术
在新无线(NR，New Radio，也被称为5G)系统中，为了获得下行数据，终端设备需要对物理下行控制信道(PDCCH，Physical Downlink Control Channel)进行监听，来判断是否有下行调度信息。监听PDCCH的过程为：终端设备进行PDCCH译码，再通过循环冗余校验(CRC，Cyclic Redundancy Check)校验判断是否为携带终端设备调度信息的下行链路控制信息(DCI，Downlink Control Information)。
为了帮助理解本公开实施例的方案，以下将对本文可能涉及的相关概念进行简单介绍：
1)PDCCH监听：
基站会通过系统消息为用户分配一个或多个搜索空间(search space)，每个搜索空间的配置是周期性的，终端设备在所配置的搜索空间进行PDCCH检测。终端设备每次进行PDCCH检测的时刻被称为PDCCH监听机会(PDCCH monitoring occasion)。另外，搜索空间一般是周期性配置。
2)载波聚合(CA)传输
在CA传输过程中，用户初始的连接建立的小区称为主小区(Pcell，Primary cell)。在Pcell的基础上，提供额外的资源进行数据传输的小区称为辅小区(Scell，Secondary Cell)。
3)多小区列表的存储：
在进行无线资源控制配置(RRC configuration)时，通常可以通过CellGroupConfig→sCell ToAddModList为终端(UE)配置辅小区列表(Scell列表)，UE会对Scell列表进行维护。其中，Scell添加/修改/删去是通过SCellIndex进行小区指示。SCellIndex是Scell的一个短标识，具体的Scell信息通过ServingCellConfigCommon中具体信息单元(IE)进行配置。
4)多小区的PDCCH监听过程：
根据3GPP TR38.321中，当Scell被激活，UE需要对Scell进行监听，并重启Scell去激活定时器(sCellDeactivationTimer)。当Scell去激活定时器未超时时或没有收到MAC CE的去激活命令之前，Scell处于激活状态，此时，UE需要对该Scell的PDCCH进行持续的监听。
5)多小区的调度的过程：
下行调度时，基站(如gNB)可以向UE发送下行调度的DCI format 1_1，指示用户在不同的Scell上的资源分配情况。
对于下行激活多个Scell的情况，多个SCell调度可以令数据传输更具灵活性，但在Scell定时器超时或接收到去激活命令前，终端需要一直对激活的Scell的PDCCH进行监听，上述监听行为取决于辅小区是否激活，因此监听的灵活性较差。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。说明书以及权利要求中“和/或”表示所连接对象的至少其中之一。
本文所描述的技术不限于长期演进型(Long Time Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code  Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
如前文所述的，相关技术在下行激活了一个或多个Scell的情况下，在Scell定时器超时或接收到去激活命令前，终端需要一直对激活的Scell的PDCCH进行监听，因此其PDCCH监听的灵活性较差，且会产生较高的设备功耗，特别是在Scell上没有数据传输时，将会导致不必要的耗电。
为解决以上问题中的至少一个，本公开实施例提供了一种PDCCH的监听方法，可以提高PDCCH监听的灵活性，另外还可以减少监听功耗。
首先请参见图1，图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备(这里，网络侧设备以基站12为例进行说明)。其中，终端11也可以称作用户终端或用户设备(UE，User Equipment)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝 上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。基站12可以是各种基站和/或核心网网元，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，其中，基站12可被称为节点B、演进节点B、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，在本公开实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
基站12可在基站控制器的控制下与终端11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站12可经由一个或多个接入点天线与终端11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端11到基站12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从基站12到终端11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
为帮助理解本公开实施例，对本公开实施例涉及的相关信令进行说明。
节电信令：网络设备可以将本公开实施例采用的PDCCH监听指示信息和/或监听小区指示信息，携带在节电信令中发送给终端。这里，节电信令可以是一种专用信令，专用信令是指网络设备下发的，且可以单独实现某些功能的信令。
下行信令：下行信令泛指在用于指示下行传输的信令，本文中的下行信令中除了携带用于指示终端设备进行下行数据传输的调度信息之外，还可以携带PDCCH监听指示信息。下行信令包括DCI和媒体访问控制元素(Medium Access Control Control Element，MAC CE)等多种信令。网络设备可以通过多种下行信令中的某一种下行信令来发送PDCCH监听指示信息，也可以通过多种下行信令来发送PDCCH监听指示信息。通过多种下行信令来发送PDCCH监听指示信息，可以提高终端设备接收PDCCH监听指示信息的可靠性。
网络设备可以将PDCCH监听指示携带在DCI中，通过DCI将PDCCH监听指示信息发送给终端设备，例如，网络设备将PDCCH监听指示携带在格式1_0或格式1_1的DCI中。
或者，网络设备可以将PDCCH监听指示携带在MAC CE中，网络设备通过MAC CE将PDCCH监听指示信息发送给终端设备。
例如，网络设备将PDCCH监听信息指示携带在MAC CE中，该PDCCH监听信息指示可以是1bit信息，也可以是2bits信息。以1bit信息的PDCCH监听信息指示为例，且，PDCCH监听信息指示为终端设备是否改变PDCCH监听周期。
请参照图2，本公开实施例提供的PDCCH的监听方法，在应用于终端侧 时，包括：
步骤21，接收网络设备发送的携带有PDCCH监听指示信息和/或监听小区指示信息的节电信令，所述PDCCH监听指示信息用于指示是否改变第一PDCCH监听，所述第一PDCCH监听是在所述终端配置的搜索空间中的周期性的PDCCH监听，所述监听小区指示信息用于指示需要执行PDCCH监听的小区。
这里，网络设备可以通过终端的主小区发送所述节电信令。所述PDCCH监听指示信息用于指示是否改变第一PDCCH监听，具体可以指示是否改变在主小区和/或激活辅小区上的第一PDCCH监听。需要说明的是，这里的所述第一PDCCH监听，是指基于终端所配置的搜索空间所执行的周期性的PDCCH监听，即相关技术中的常规的PDCCH监听行为。
步骤22，根据所述节电信令中的PDCCH监听指示信息和/或监听小区指示信息的节电信令，进行PDCCH监听。
这里，所述改变所述第一PDCCH监听包括跳过所述第一PDCCH监听、变更所述第一PDCCH监听的PDCCH监听周期等。例如，在所述PDCCH监听指示信息指示跳过所述第一PDCCH监听时，终端可以不再在对应小区上执行所述第一PDCCH监听，这样，即使某个辅小区处于激活状态，也可以通过本公开实施例的以上方案，不再在该小区上进行相关技术的常规PDCCH监听，从而可以实现一种灵活的PDCCH监听方案，另外，停止进行上述常规的PDCCH监听，还可以减少终端的设备功耗，延长终端的待机时间。
网络设备可以根据各种策略，确定是否需要控制某个终端跳过主小区和/或至少一个辅小区的所述第一PDCCH监听，例如，在缓存中不存在待发送至所述终端的数据时，发送所述节电信令，控制终端跳过主小区和/或辅小区的第一PDCCH监听。又例如，在调度终端数据传输的过程中，可以根据剩余数据确定是否需要控制终端跳过主小区和/或辅小区的第一PDCCH监听。
通过以上步骤，本公开实施例可以实现灵活的PDCCH监听，另外还能够降低终端的设备功耗。
根据本公开的至少一个实施例，所述PDCCH监听指示信息可以包括以下信息中的至少一种：
第一指示信息，用于指示是否跳过所述第一PDCCH监听；
第二指示信息，用于指示是否跳过所述第一PDCCH监听，并在跳过所述第一PDCCH监听时指示下一个PDCCH监听机会；
第三指示信息，用于指示是否变更PDCCH监听周期，并在变更后的PDCCH监听周期进行PDCCH监听；
第四指示信息，用于指示是否变更PDCCH监听周期，，并指示变更后的PDCCH监听周期，或变更后PDCCH监听周期所对应的索引。
其中，在所述PDCCH监听指示信息为所述第一指示信息时，所述终端还可以接收网络设备通过高层信令为所述终端配置的在跳过所述第一PDCCH监听时的下一个PDCCH监听机会，从而可以在所述第一指示信息指示跳过所述第一PDCCH监听时，根据所述高层信令的配置，确定在跳过所述第一PDCCH监听时的下一个PDCCH监听机会。
又例如，在所述PDCCH监听指示信息为所述第三指示信息时，所述终端还可以接收网络设备通过高层信令为所述终端配置的变更后的PDCCH监听周期，以及，根据所述高层信令配置的变更后的PDCCH监听周期，确定在改变所述第一PDCCH监听时的下一个PDCCH监听机会。
又例如，在所述PDCCH监听指示信息为所述第四指示信息时，所述终端还可以接收网络设备通过高层信令为所述终端配置的所述第四指示信息的不同取值与所述变更后的PDCCH监听周期(或变更后PDCCH监听周期所对应的索引)之间的对应关系，以及，在所述第四指示信息指示变更PDCCH监听周期时，根据所述高层信令配置的所述对应关系，确定所述第四指示信息对应的变更后的PDCCH监听周期(或变更后PDCCH监听周期所对应的索引)，进而确定在改变所述第一PDCCH监听时的下一个PDCCH监听机会。
下面进一步给出了所述PDCCH监听指示信息的若干具体示例。
PDCCH监听指示信息指示，具体可以采用1比特指示，也可以采用2比特指示，可以有以下几种形式：
对应上述第一指示信息的形式一：指示终端是否跳过PDCCH监听；
对应上述第二指示信息的形式二：指示下一个PDCCH监听机会N，N>1；
对应于上述第三指示信息的形式三：指示PDCCH的监听周期是否变更；
对应上述第四指示信息的形式四：指示变更后的PDCCH的监听周期K，或变更后PDCCH监听周期所对应的索引，K>1。
1)对于PDCCH监听指示信息的形式一：
假设采用1比特指示信息，则该信息用于指示是否跳过PDCCH监听。例如，指示信息为“0”，则指示终端执行相关技术的常规PDCCH监听模式(上文的上述第一PDCCH监听)，即，在搜索空间中的下一个PDCCH监听机会要进行PDCCH监听；例如，指示信息为“1”，则指示终端需要跳过PDCCH监听，下一个PDCCH监听机可以由高层信令预配置。
2)对于PDCCH监听指示信息的形式二：
假设采用2比特指示信息，则该信息用于指示终端下一个进行PDCCH监听机会，例如：
‘00’指示在搜索空间中的下一个PDCCH监听机会进行PDCCH监听(即执行本文的所述第一PDCCH监听)；
‘01’指示在第N 1个PDCCH监听机会进行PDCCH监听；
‘10’指示在第N 2个PDCCH监听机会进行PDCCH监听；
‘11’指示在第N 3个PDCCH监听机会进行PDCCH监听；
在上述PDCCH监听指示信息取值为‘00’时，指示终端执行相关技术的常规PDCCH监听模式(即本文的所述第一PDCCH监听)；而在上述PDCCH监听指示信息取值非‘00’时，指示终端跳过相关技术的常规PDCCH监听模式，而在与所述第一下行信令对应的当前PDCCH间隔N 1-1个PDCCH监听机会的第N 1个PDCCH监听机会进行PDCCH监听，或者，指示终端在与所述第一下行信令对应的当前PDCCH间隔N 2-1个PDCCH监听机会的第N 2个PDCCH监听机会进行PDCCH监听，或者，指示终端在与所述第一下行信令对应的当前PDCCH间隔N 3-1个PDCCH监听机会的第N 3个PDCCH监听机会进行PDCCH监听。
3)对于PDCCH监听指示信息的形式三：
假设采用1比特指示信息，则该信息用于指示PDCCH监听周期是否改变。例如，在PDCCH监听指示信息为‘0’，则指示不改变PDCCH监听周期， 即，按高层信令配置的监听周期K进行PDCCH监听(即执行本文的所述第一PDCCH监听)，如K＝1，则每个PDCCH监听机会都进行PDCCH监听；例如，在PDCCH监听指示信息为‘1’，则指示终端需要改变PDCCH监听周期，更改后的PDCCH监听周期可以由高层信令(如RRC信令)配置。
4)对于PDCCH监听指示信息的形式四：
对于2比特的PDCCH监听指示信息的情况，可以用于指示变更后的PDCCH的监听周期，或者指示PDCCH监听周期的变更后的值所在预先配置的PDCCH监听周期集合中的索引值，其中PDCCH监听周期集合可以高层信令预配置。例如，高层信令预配置的PDCCH监听周期集合为{K 1时隙,K 2时隙,K 3时隙,K 4时隙}，上述集合中的K 1表示与所述第一下行信令对应的当前PDCCH所在的当前时隙，间隔K 1-1个时隙的第K 1个时隙中的PDCCH监听机会。具体的，接收到的PDCCH监听指示可以有以下情况：
‘00’指示PDCCH监听周期为第K 1时隙的监听机会；
‘01’指示PDCCH监听周期为第K 2时隙的监听机会；
‘10’指示PDCCH监听周期为第K 3时隙的监听机会；
‘11’指示PDCCH监听周期为第K 4时隙的监听机会；
如果当前时刻DCI有终端的调度信息，该终端能够通过CRC校验得到DCI中所携带的PDCCH监听指示信息，那么终端根据PDCCH监听指示来获得后续的PDCCH监听行为，如指示下一个PDCCH监听机会，或PDCCH监听周期的变化情况，或PDCCH监听周期变更为何值。
如果当前时刻DCI中没有该终端的调度信息，该终端不能CRC校验译得DCI中所携带的PDCCH监听指示信息，那么终端可以通过接收节电信令，读取其中所携带的PDCCH监听指示信息来获得后续的PDCCH监听行为，如指示下一个PDCCH监听机会，或PDCCH监听周期的变化情况，或PDCCH监听周期变更为何值。
根据本公开的至少一个实施例，所述监听小区指示信息包括以下信息中的至少一种：
第五指示信息，用于指示进行监听的辅小区的第一数量；
第六指示信息，用于指示进行监听的辅小区信息。
根据本公开的至少一个实施例，，在所述第五指示信息或第六指示信息指示的辅小区为全零比特时，表示仅在主小区上进行监听；在所述第五指示信息或第六指示信息指示的辅小区非全零比特时，表示在主小区以及所述第五指示信息或第六指示信息指示的辅小区上进行监听。
例如，在所述监听小区指示信息为所述第五指示信息时，所述第五指示信息指示的辅小区按照以下任一方式确定：
1)根据高层信令配置的所述第一数量的辅小区列表，确定所述第五指示信息指示的辅小区；
2)根据高层信令配置的辅小区的不同数量与辅小区列表之间的对应关系，确定所述第一数量对应的辅小区列表；
3)按照预定的排序算法从多个辅小区中选择所述第一数量的辅小区。
下面进一步给出了所述监听小区指示信息的若干具体示例。
监听小区指示信息形式一(对应于上述第五指示信息)：
所述监听小区指示信息为N比特的信息，用来指示需要监听的辅小区(组)的个数M。如，N＝5，M为5比特二进制信息所对应的十进制数，该信息最大可以指示31个Scell。另外，Scell或Scell组的列表是基于基站的高层信令预配置的。当监听小区指示信息为全零比特(即所有比特均为0)或零个比特时，表示没有Scell需要进行PDCCH监听，终端只需要监听主小区(Pcell)的PDCCH或节电信令。当所述监听小区指示信息为非全零比特(即不是所有比特都为0)或零个比特时，具体的监听小区可以通过以下几种方式确定：
方式一：根据高层信令半静态配置
基站通过Pcell的高层信令对待监听的Scell或Scell组进行配置。
方式二：根据高层信令预配置包括不同个数的Scell或Scell组的Scell列表清单。
例如，基站预先为用户配置一个针对节电信令的Scell列表清单，对应着的不同的Scell个数，如下表1所示：
Figure PCTCN2020083167-appb-000001
Figure PCTCN2020083167-appb-000002
表1
这里的Scell(s)i是高层信令配置的Scell或Scell组索引，不同列表中的索引可以相同，也可以不同。
方式三：根据基站和终端预先达成一致的排序算法排序，从多个辅小区(组)中的前M个
监听小区指示信息形式二(对应于上述第六指示信息)：
所述监听小区指示信息为M比特信息，M为Scell或Scell组的总个数，用来指示PDCCH监听指示信息的具体的Scell，每一位比特对应一个Scell或一个Scell组，当该比特为“1”时，表示需要对该Scell或Scell组采用相应的PDCCH监听行为，具体的监听行为由PDCCH监听指示信息确定。当Scell列表为全“0”时，表示没有Scell或Scell组需要进行PDCCH监听，此时终端只需要监听主小区(Pcell)的PDCCH和/或节电信令。
另外，对于节电信令中的PDCCH监听指示信息，该PDCCH监听指示信息可以是针对Pcell以及监听小区指示信息中的小区的共同监听动作，也可以是分别针对各个Scell或Scell组进行独立指示。
根据本公开的至少一个实施例，在上述步骤22中，所述终端可以在所述节电信令中的所述PDCCH监听指示信息和/或监听小区指示信息指示改变所述第一PDCCH监听时，根据高层信令和/或所述节电信令中携带的所述PDCCH监听指示信息和/或监听小区指示信息，确定第一目标PDCCH监听机会；然后，在所述第一目标PDCCH监听机会监听网络设备发送的下行信令和/或节电信令，其中，所述下行信令携带有所述PDCCH监听指示信息和/或监听小区指示信息。
进一步的，所述终端还可以根据所述第一目标PDCCH监听机会处监听到的所述下行信令和/或节电信令中的所述PDCCH监听指示信息和/或监听小区指示信息，改变或恢复所述第一PDCCH监听。
更进一步的，在所述第一目标PDCCH监听机会监听网络设备发送的所述下行信令和/或节电信令之后，所述终端还可以根据所述第一目标PDCCH监听机会处监听到的所述下行信令和/或节电信令中的所述PDCCH监听指示信息和/或监听小区指示信息，确定是否改变所述第一PDCCH监听：
1)在确定改变所述第一PDCCH监听时，可以根据高层信令以及所述第一目标PDCCH监听机会处监听到的所述PDCCH监听指示信息和/或监听小区指示信息，确定下一目标PDCCH监听机会，并在所述下一目标PDCCH监听机会继续监听网络设备发送的所述下行信令和/或节电信令，也即，在所述下一目标PDCCH监听机会继续监听网络设备发送的所述下行信令和/或新的节电信令，从而可以通过重复执行上述过程，改变或恢复所述第一PDCCH监听。
具体的，所述终端可以在所述监听小区指示信息指示的辅小区为全零比特时，针对所述主小区，在所述下一目标PDCCH监听机会监听网络设备发送的所述下行信令和/或节电信令。而在所述监听小区指示信息指示的辅小区非全零比特时，针对所述主小区以及所述监听小区指示信息指示的辅小区，在所述下一目标PDCCH监听机会监听网络设备发送的所述下行信令。
2)在确定不改变所述第一PDCCH监听时，可以恢复所述第一PDCCH监听。
这里，恢复所述第一PDCCH监听，具体可以包括：1)在所述监听小区指示信息指示的辅小区为全零比特时，针对所述主小区恢复所述第一PDCCH监听；2)在所述监听小区指示信息指示的辅小区非全零比特时，针对所述主小区以及所述监听小区指示信息指示的辅小区，恢复所述第一PDCCH监听。
这样，通过以上方式，本公开实施例的终端可以确定下一个PDCCH监听时机，包括所述第一PDCCH监听中的下一个PDCCH监听时机，以及，在改变所述第一PDCCH监听时的下一个PDCCH监听机会(即所述第一目标PDCCH监听机会)。例如，所述网络设备还可以在改变所述第一PDCCH监听时的下一个PDCCH监听机会，继续发送下行信令和/或节电信令，所述下行信令携带有所述PDCCH监听指示信息和/或监听小区指示信息。这里，监听小区指示信息可以与所述PDCCH监听指示信息配合使用，从而确定需要 监听的小区及其监听时机。
另外，根据本公开的至少一个实施例，在上述步骤21之前，所述终端还可以接收网络设备发送的携带有所述PDCCH监听指示信息和/或监听小区指示信息的第一下行信令；然后，在所述第一下行信令中的所述PDCCH监听指示信息和/或监听小区指示信息指示改变所述第一PDCCH监听时，可以根据高层信令和/或所述第一下行信令中携带的所述PDCCH监听指示信息和/或监听小区指示信息，确定第二目标PDCCH监听机会。然后，在步骤21中，所述终端可以在所述第二目标PDCCH监听机会监听并接收所述节电信令。
作为一个具体例子，在所述第一下行信令调度传输的数据为所述终端的最后一个数据包时，网络设备可以在所述第一下行控制信令中携带的所述PDCCH监听指示信息和/或监听小区指示信息中，指示改变所述第一PDCCH监听；而在所述第一下行信令调度传输的数据不是所述终端的最后一个数据包时，所述第一下行信令中的所述PDCCH监听指示信息和/或监听小区指示信息可以用于指示不改变所述第一PDCCH监听。
以上从终端侧对本公开实施例的PDCCH监听方法进行了说明。下面将进一步从网络侧进行描述。
请参照图3，本公开实施例提供的PDCCH的监听方法，在应用于网络设备(如基站)时，包括：
步骤31，向终端发送携带有PDCCH监听指示信息和/或监听小区指示信息的节电信令，所述PDCCH监听指示信息用于指示是否改变第一PDCCH监听，所述第一PDCCH监听是在所述终端配置的搜索空间中的周期性的PDCCH监听，所述监听小区指示信息用于指示需要执行PDCCH监听的小区。
通过以上步骤，本公开实施例的网络设备可以控制终端实现灵活的PDCCH监听。例如，网络设备可以根据各种策略，确定是否需要控制某个终端改变所述第一PDCCH监听，其中，所述改变所述第一PDCCH监听包括跳过所述第一PDCCH监听、变更所述第一PDCCH监听的PDCCH监听周期等。具体的，可以在缓存中不存在待发送至所述终端的数据时，发送所述节电信令，控制终端跳过主小区和/或辅小区的第一PDCCH监听。又例如，在调度终端数据传输的过程中，可以根据剩余数据确定是否需要控制终端跳过 主小区和/或辅小区的第一PDCCH监听。
根据本公开至少一个实施例，所述PDCCH监听指示信息可以包括以下信息中的至少一种：
第一指示信息，用于指示是否跳过所述第一PDCCH监听；

进一步，在所述第五指示信息或第六指示信息指示的辅小区为全零比特时，表示仅在主小区上进行监听；在所述第五指示信息或第六指示信息指示的辅小区非全零比特时，表示在主小区以及所述第五指示信息或第六指示信息指示的辅小区上进行监听。另外，关于上述第五/第六指示信息的更详细的说明，可以参考上文的描述，为节约篇幅，此处不再赘述。
另外，关于上述各个指示信息的更详细的说明，可以参考上文的描述，为节约篇幅，此处不再赘述。

根据本公开至少一个实施例，在所述PDCCH监听指示信息为所述第四指示信息时，所述网络设备还可以通过高层信令为所述终端配置所述第四指 示信息的不同取值与所述变更后的PDCCH监听周期之间的对应关系。
根据本公开至少一个实施例，在所述监听小区指示信息为所述第五指示信息时，所述网络设备还可以执行以下动作，以帮助所述终端确定需要监听的辅小区：
1)通过高层信令为所述终端配置所述第一数量的辅小区列表；
2)通过高层信令为所述终端配置辅小区的不同数量与辅小区列表之间的对应关系；
3)按照预定的排序算法从多个辅小区中选择所述第一数量的辅小区。
根据本公开的至少一个实施例，所述网络设备在所述目标PDCCH监听机会向所述终端发送所述节电信令之前，还可以根据第一条件，设置所述目标PDCCH监听机会发送的所述节电信令中的所述PDCCH监听指示信息和/或监听小区指示信息，所述第一条件包括以下条件中的至少一个：是否需要所述终端继续改变所述第一PDCCH监听，以及，在需要所述终端继续改变所述第一PDCCH监听时，所述终端的下一目标PDCCH监听机会；以及，根据需要进行所述第一PDCCH监听的小区或需要在所述下一目标PDCCH监听机会进行监听的小区，设置所述节电信令中的监听小区指示信息。
在上述步骤31中，若所述节电信令中的所述PDCCH监听指示信息和/或监听小区指示信息指示改变所述第一PDCCH监听，所述网络设备还可以根据高层信令和/或所述节电信令中携带的所述PDCCH监听指示信息和/或监听小区指示信息，确定第一目标PDCCH监听机会，并在所述第一目标PDCCH监听机会向所述终端发送下行信令和/或节电信令，其中，所述下行信令携带有所述PDCCH监听指示信息和/或监听小区指示信息。
通过以上步骤，可以实现控制终端改变所述第一PDCCH监听，并在网络设备指示的新的PDCCH监听机会处继续监听第一下行信令和/或节电信令。
根据本公开的至少一个实施例，在上述步骤31之前，所述网络设备还可以向所述终端发送用于调度携带有所述PDCCH监听指示信息和/或监听小区指示信息的第一下行信令。

以上分别从终端侧和网络侧介绍了本公开实施例的所述方法。下面将进一步结合若干具体实施例对以上方法进行更为详细的说明。
示例1：采用5比特的监听小区指示信息
基站侧：
1、通过在调度DCI中引入PDCCH监听改变指示信息，用于指示终端是否改变对Pcell或Scell的PDCCH监听动作。每个Scell或Scell组由各自调度的DCI中的PDCCH监听指示信息进行指示。
2、当最后一个数据包调度时，基站通过DCI向终端发送PDCCH监听指示，为非全零比特值，指示终端进行PDCCH监听改变。这里的DCI包括Pcell以及所有激活的Scell的调度DCI。例如：
1)如果PDCCH监听指示信息采用的是形式一，且为“1”，那么对相应的Cell进行PDCCH监听跳过，下一个PDCCH监听机会由高层信令进行预 配置。
2)如果PDCCH监听指示信息采用的是形式二，且为“01”，那么对相应的Cell进行PDCCH监听跳过，并在第N 1个监听机会进行监听。
3)如果PDCCH监听指示信息采用的是形式三，且为“1”，那么对相应的Cell的PDCCH监听周期发生改变，更改后的监听周期由高层信令配置。
4)如果PDCCH监听指示信息采用的是形式四，且为“01”，那么对相应的Cell的PDCCH监听周期调整为K 2。
进一步地，上述PDCCH监听改变仅以一个搜索空间为例，同样适用于多个搜索空间，且多个搜索空间的PDCCH监听指示信息可以是相同的动作，也可以是不同的动作。
3、当触发PDCCH监听改变后，基站通过节电信令向终端发送PDCCH监听指示信息以及对相应的监听小区指示信息。
4、如果没有下行数据调度，监听小区指示信息指示的是全零，PDCCH监听指示信息为非全零比特值，用户主要通过节电信令监听后续的PDCCH监听改变方式，具体指示形式参见上述第2点。
5、当在PDCCH监听机会到达或之前有数据到达时，基站通过节电信令携带的监听小区指示信息指示终端对哪些Scell进行监听，同时将PDCCH监听指示信息复位，即设置为0，表示终端将在下一个PDCCH监听机会进行PDCCH监听。
如果监听小区指示信息采用5比特信息且监听小区指示信息全为0，则表示终端只需在下一个监听机会上在Pcell上进行PDCCH监听，等待数据调度。
如果监听小区指示信息采用5比特信息且监听小区指示信息为非全零比特时，如00010，终端会根据监听小区指示信息所指示的Scell或Scell组个数，即M＝(00010) 10＝4个Scell或Scell组，进行相应的PDCCH监听。具体的监听Scell或Scell组的确定方法有以下几种：
方式一：根据高层信令半静态配置
基站通过Pcell的高层信令对待监听的Scell或Scell组进行配置。
方式二：根据高层信令预配置不同个数Scell或Scell组列表清单。
基站预先为用户配置一个针对节电信令的Scell或Scell组列表清单，对应着的不同的Scell个数，如下表所示：
Scell或Scell组个数 Scell或Scell组列表
1 {Scell(s)1}
2 {Scell(s)21，Scell(s)22}
3 {Scell(s)31，Scell(s)32，Scell(s)33}
…… ……
M＝2N-1 {Scell(s)M1，Scell(s)M2，…….，Scell(s)MM}
   
   
   
   
   
   
注：这里的Scell(s)i和Scell(s)j是高层信令配置的Scell或Scell组索引，不同列表中的索引可以相同，也可以不同。
方式三：根据基站和用户达成一致的排序算法排序，取前M个。
由于基站与用户采用达成一致的排序算法，基站只需要对待监听的Scell个数进行指定即可。
如果所述Scell因为收到去激活命令或Scell去激活定时器超时，处于去激活状态，那么：
1)如果节电信令不具有Scell激活功能，基站通过PCell的MAC CE的Scell激活命令进行相应的Scell激活。
2)如果节电信令具有Scell激活功能，基站通过PCell的高层信令进行Scell列表配置。
如果所述Scell都处于激活状态，则基站不需要对相应的Scell进行激活。
终端侧：
1、当终端能够获得调度DCI中的PDCCH监听指示信息，则终端按PDCCH监听指示信息改变后续的PDCCH监听动作。
1)如果PDCCH监听指示信息采用的是形式一，且为“1”，那么对相应的Cell进行PDCCH监听跳过，下一个PDCCH监听机会由高层信令进行预配置。
2)如果PDCCH监听指示信息采用的是形式二，且为“01”，那么对相应的Cell进行PDCCH监听跳过，并在N 1监听机会进行监听。
3)如果PDCCH监听指示信息采用的是形式三，且为“1”，那么对相应的Cell的PDCCH监听周期发生改变，更改后的监听周期由高层信令配置。
4)如果PDCCH监听指示信息采用的是形式四，且为“01”，那么对相应的Cell的PDCCH监听周期调整为K 2。
例如，当没有数据传输时，基站会通过调度DCI指示用户跳过所有Cell(包括Pcell和Scell)的PDCCH监听，PDCCH监听指示信息为非全零比特值。
2、终端接收下行信令，如调度DCI，中的PDCCH改变指示后，会按PDCCH监听指示信息所指示的动作进行节电信令的监听，同时改变对所有Cell(包括Pcell和Scell)的PDCCH监听。
3、当无数据传输时，终端主要进行节电信令的监听，此时，节电信令携带的PDCCH监听指示为非全零比特值，监听小区指示信息为全零值，其中，PDCCH监听指示为后续的节电信令的监听时刻。
4、当终端接收到的节电信令的PDCCH监听指示信息为全零比特，那么终端则在下一个PDCCH监听机会对相应的Cell进行PDCCH监听。
A)如果监听小区指示信息为全零，终端只需要对Pcell进行PDCCH监听；
B)如果监听小区指示信息为非全零值，如00010，终端除了对Pcell进行监听之外，还需要根据监听小区指示信息所指示的Scell(s)个数，即M＝(00010) 10＝4个Scell(s)，用户首先确定待监听的4个Scell。
对于不同的Scell列表的指示方法，终端获得监听小区指示信息不同，具体如下：
方式一：根据高层信令半静态配置
通过Pcell的高层信令来获得监听小区指示信息，并相应的Scell(s)的 PDCCH监听。
方式二：根据高层信令预配置不同个数Scell(s)列表清单。
由于基站高层信令预配置了监听小区指示信息清单，终端只需根据Scell列表所指示的Scell(s)找到相应的Scell(s)进行PDCCH监听即可。
方式三：根据基站和用户达成一致的排序算法排序，取前M个。
如果存在激活的Scell(s)大于等于M个，可参考的具体实现方式有：
a)如按sCellDeactivationTimer距离超时的时间长短排序后的前4个Scell(s)。
b)如按历史的统计的Scell信道质量，如RSRP/RSRQ/CQI等，进行排序取前4个Scell(s)。
c)如最近一次调度数据的4个Scell(s)。
当然，以上仅为排序算法的举例，本公开实施例不局限于上述几种。
如果存在激活的Scell(s)小于M个，终端待收到基站发送的Scell(s)激活命令的MAC CE或节电信令，进行Scell(s)的PDCCH监听。
示例2：采用32比特的监听小区指示信息
基站侧：
1、通过在调度DCI中引入PDCCH监听改变指示信息，用于指示终端是否改变对Pcell或Scell的PDCCH监听动作。每个Scell由各自调度的DCI中的PDCCH监听指示信息进行指示。
2、当最后一个数据包调度时，基站通过DCI向终端发送PDCCH监听指示，为非全零比特值，指示终端进行PDCCH监听改变。这里的DCI包括Pcell以及所有激活的Scell的调度DCI。例如：
1)如果PDCCH监听指示信息采用的是形式一，且为“1”，那么对相应的Cell进行PDCCH监听跳过，下一个PDCCH监听机会由高层信令进行预配置。
2)如果PDCCH监听指示信息采用的是形式二，且为“01”，那么对相应的Cell进行PDCCH监听跳过，并在N 1监听机会进行监听。
3)如果PDCCH监听指示信息采用的是形式三，且为“1”，那么对相应的Cell的PDCCH监听周期发生改变，更改后的监听周期由高层信令配置。
4)如果PDCCH监听指示信息采用的是形式四，且为“01”，那么对相应的Cell的PDCCH监听周期调整为K 2。
进一步地，上述PDCCH监听改变仅以一个搜索空间为例，同样适用于多个搜索空间，且多个搜索空间的PDCCH监听指示信息可以是相同的动作，也可以是不同的动作。
3、当触发PDCCH监听改变后，基站通过节电信令向终端发送PDCCH监听指示信息以及对相应的监听小区指示信息。
4、如果没有下行数据调度，监听小区指示信息指示的是全零，PDCCH监听指示信息为非全零比特值，用户主要通过节电信令监听后续的PDCCH监听改变方式，具体指示形式参见上述第2点。
5、当在PDCCH监听机会到达或之前有数据到达时，基站通过节电信令携带的监听小区指示信息指示终端对哪些Scell进行监听，同时将PDCCH监听指示信息复位，即设置为0，表示终端将在下一个PDCCH监听机会进行PDCCH监听。
如果Scell(s)全为0，则表示终端只需在下一个监听机会上在Pcell上进行PDCCH监听，等待数据调度。
如果监听小区指示信息采用31比特信息且监听小区指示信息为非全零比特时，如01000000 1000000 00000001 0000100，即指示的是Scell索引{2，9，24，29}，终端会根据监听小区指示信息所指示的Scell进行PDCCH监听。
如果所述Scell因为收到去激活命令或Scell去激活定时器超时，处于去激活状态，那么：
1)如果节电信令不具有Scell激活功能，基站通过PCell的MAC CE的Scell激活命令进行相应的Scell激活。
2)如果节电信令具有Scell激活功能，基站通过PCell的高层信令进行Scell列表配置。
如果所述Scell都处于激活状态，则基站不需要对相应的Scell进行激活。
注：上述方法也适用于指示Scell组，这里不作赘述。
终端侧：
1、当终端能够获得调度DCI中的PDCCH监听指示信息，则终端按 PDCCH监听指示信息执行后续的PDCCH监听动作。
1)如果PDCCH监听指示信息采用的是形式一，且为“1”，那么对相应的Cell进行PDCCH监听跳过，下一个PDCCH监听机会由高层信令进行预配置。
2)如果PDCCH监听指示信息采用的是形式二，且为“01”，那么对相应的Cell进行PDCCH监听跳过，并在N 1监听机会进行监听。
3)如果PDCCH监听指示信息采用的是形式三，且为“1”，那么对相应的Cell的PDCCH监听周期发生改变，更改后的监听周期由高层信令配置。
4)如果PDCCH监听指示信息采用的是形式四，且为“01”，那么对相应的Cell的PDCCH监听周期调整为K 2。
例如，当没有数据传输时，基站会通过调度DCI指示用户跳过所有Cell(包括Pcell和Scell)的PDCCH监听，PDCCH监听指示信息为非全零比特值。
2、终端接收下行信令，如调度DCI，中的PDCCH改变指示后，会按PDCCH监听指示信息所指示的动作进行节电信令的监听，同时跳过对所有Cell(包括Pcell和Scell)的PDCCH监听。
3、当无数据传输时，终端主要进行节电信令的监听，此时，节电信令携带的PDCCH监听指示为非全零比特值，监听小区指示信息为全零值，其中，PDCCH监听指示为后续的节电信令的监听时刻。
4、当有新的数据到达时，终端接收到的节电信令的PDCCH监听指示信息为全零比特，那么终端则在下一个PDCCH监听机会对相应的Cell进行PDCCH监听。
a)如果监听小区指示信息为全零，终端只需要对Pcell进行PDCCH监听；
b)如果监听小区指示信息为非全零值，终端除了对Pcell进行PDCCH监听，还要根据监听小区指示信息，如01000000 1000000 00000001 0000100，即指示的是Scell索引{2，9，24，29}，终端对所指示的Scell进行PDCCH监听。
