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。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统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系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(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。
该通信系统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系统(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/或全球定位系统(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。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G系统或5G网络还可以称为新无线(New Radio，NR)系统或NR网络。
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，该通信系统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，该通信系统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/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统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系统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“系统”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。
考虑到通过RRC消息指示激活或者更新SRS resource set中的pathloss RS时延较大，因此，本申请实施例提供了一种激活或者更新探测参考信号对应的路损参考信号的方法，可以通过介质访问控制(medium access control，MAC)控制元素(control element，CE)进行指示。
具体地，图2为本申请实施例提供的一种激活或者更新探测参考信号对应的路损参考信号的方法200的示意性流程图。如图2所示，该方法200包括：S210，发送MAC CE，即网络设备向终端设备发送MAC CE。其中，该MAC CE包括至少一个SRS resource set字段和/或至少一个pathloss RS字段，该至少一个SRS resource set字段用于指示至少一个SRS resource set，该至少一个pathloss RS字段用于指示与该至少一个SRS resource set对应的至少一个pathloss RS。
应理解，上述的这一类MAC CE可以通过逻辑信道标识符(logical channel identifier，LCID)进行区分。例如，该MAC CE所在的MAC协议数据单元(Protocol Data Unit，PDU)的包头中或者MAC subPDU的包头中包括LCID字段，该LCID字段用于指示该MAC CE的类型。另外，用于指示本申请实施例中该MAC CE类型的LCID的取值可以根据实际应用进行设置，例如，可以选择33-46之间任意值，但本申请实施例并不限于此。
可选地，该MAC CE还可以包括服务小区(Serving Cell)标识字段，该服务小区标识字段用于指示该终端设备驻留的服务小区的ID。该服务小区标识字段的大小可以根据服务小区的最大个数进行设置，例如，若服务小区的最大个数为32，那么对应的服务小区标识字段占用5bits(比特)。
可选地，该MAC CE还包括带宽部分(bandwidth part，BWP)标识字段，该带宽部分标识字段用于指示该终端设备对应的BWP ID。该带宽部分标识字段的大小可以根据带宽部分的最大个数进行设置，例如，若带宽部分的最大个数为4，那么对应的该带宽部分标识字段占用2bits。
可选地，该MAC CE还可以包括保留比特位，用“R”表示，但本申请实施例并不限于此。
应理解，本申请实施例的方法200可以由终端设备和网络设备执行。例如，该终端设备可以为如图1所示的终端设备，该网络设备可以为如图1所示的网络设备，但本申请实施例并不限于此。
如图2所示，该方法200还包括：S220，确定更新或激活的SRS resource set对应的pathloss RS，终端设备接收网络设备发送的MAC CE，根据该MAC CE，更新或者激活MAC CE指示的至少一个SRS resource set对应的该至少一个pathloss RS。
网络设备可以为终端设备配置一个或者多个SRS resource set，也可以配置一个或者多个pathloss RS，并且，SRS resource set与pathloss RS之间具有对应关系。例如，SRS Resource Set的最大个数通常为16个，Pathloss RS的最大个数通常为8个或者16个；另外，一个SRS Resource Set通常对应有一个Pathloss RS，但一个Pathloss RS可能对应一个或者多个SRS Resource Set，本申请实施例并不限于此。
可选地，网络设备可以通过RRC消息为该终端设备配置该一个或者多个SRS resource set和/或配置一个或者多个pathloss RS，本申请实施例并不限于此。
应理解，本申请实施例的MAC CE可以有多种形式，例如，MAC CE包括的至少一个SRS resource set字段和/或至少一个pathloss RS字段可以有不同设置方式。下面将结合图3至图14，详细描述各种情况，其中，图3至图14分别示出了几种不同MAC CE的格式。
可选地，作为第一个实施例，该MAC CE可以包括至少一个SRS resource set字段以及至少一个pathloss RS字段，并且，该至少一个SRS resource set字段与该至少一个pathloss RS字段一一对应，也就是说，一个SRS resource set字段对应一个pathloss RS字段，该至少一个SRS resource set字段中一个SRS resource set字段用于表示该至少一个SRS resource set中一个SRS resource set的标识(ID)，该至少一个pathloss RS字段中一个pathloss RS字段用于表示该至少一个pathloss RS中一个pathloss RS的 ID。
可选地，由于可能存在多个SRS resource set对应同一pathloss RS的情况，因此，在该第一个实施例中，MAC CE中的至少一个pathloss RS字段中可能包括多个pathloss RS字段包括了同一个pathloss RS的ID的情况。
应理解，由于SRS resource set字段用于表示SRS resource set的ID，pathloss RS字段用于表示pathloss RS的ID，所以每个SRS resource set字段的大小与SRS resource set的个数相关，每个pathloss RS字段的大小与pathloss RS的个数相关。
可选地，该方法200还可以包括：该终端设备根据该至少一个SRS resource set的个数，确定该至少一个SRS resource set字段中每个SRS resource set字段的大小。例如，如图3至图6所示，假设该至少一个SRS resource set的最大个数为16，那么每个SRS resource set字段占用4比特。
类似的，该方法200还可以包括：该终端设备根据该至少一个pathloss RS字段的个数，确定该至少一个pathloss RS字段中每个pathloss RS字段的大小。例如，如图3和图5所示，假设该至少一个pathloss RS的最大个数为8，那么每个pathloss RS字段占用3比特；再例如，如图4和图6所示，假设该至少一个pathloss RS的最大个数为16，那么每个pathloss RS字段占用4比特。
在该第一个实施例中，一个SRS resource set字段对应一个pathloss RS字段，那么对于任意一个MCA CE，该MAC CE可以用于指示一个或者多个SRS resource set对应的pathloss RS。例如，如图3和图4所示，一个MAC CE可以仅用于指示一个SRS resource set对应的一个pathloss RS，那么该MCA CE中包括一个SRS resource set字段以及一个pathloss RS字段，SRS resource set字段包括SRS resource set的ID，pathloss RS字段包括该SRS resource set对应的pathloss RS的ID，则终端设备根据该MCA CE，确定需要激活或者更新的一个SRS resource set对应的pathloss RS。若需要激活或者更新多个SRS resource set对应的pathloss RS，则可以向终端设备发送多个MAC CE。
再例如，如图5和图6所示，一个MCA CE还可以用于指示多个SRS resource set对应的pathloss RS，那么该MCA CE包括多个SRS resource set字段以及多个pathloss RS字段，其中，一个SRS resource set字段包括一个SRS resource set的ID，与之对应的一个pathloss RS字段包括该SRS resource set对应的pathloss RS的ID。假设该MCA CE包括如图5和图6所示的N个八比特组(Oct)，那么该MCA CE可以用于指示至少N-1个SRS resource set及其对应的pathloss RS，以便于终端设备根据该MCA CE，更新或者激活该N-1个SRS resource set对应的pathloss RS。
可选地，作为第二个实施例，仍然以该MAC CE包括至少一个SRS resource set字段和至少一个pathloss RS字段为例，但是与第一个实施例不同的是，该MAC CE具体包括多个SRS resource set字段，该多个SRS resource set字段一一对应于为该终端设备配置的多个SRS resource set，该多个SRS resource set字段中每个SRS resource set字段用于指示是否需要更新或者激活对应的SRS resource set的pathloss RS，也就是说，每个SRS resource set字段不再是第一个实施例中的SRS resource set的ID。
另外，该多个SRS resource set字段中表示为第一值的SRS resource set字段为该至少一个SRS resource set字段，也就是说，若该多个SRS resource set字段中某个SRS resource set字段为第一值，那么该SRS resource set字段属于上述S210中的至少一个SRS resource set字段，即该SRS resource set字段对应的SRS resource set的pathloss RS需要更新或者激活；相反的，如果该多个SRS resource set字段中某个SRS resource set字段不等于该第一值，那么该SRS resource set字段就不属于上述S210中的至少一个SRS resource set字段，即该SRS resource set字段对应的SRS resource set的pathloss RS不需要更新或者激活。
网络设备可以为终端设备配置多个SRS resource set，与之一一对应设置有多个SRS resource set字段，该多个SRS resource set字段中可能存在部分或者全部字段属于至少一个SRS resource set字段，在该MAC CE中，与该至少一个SRS resource set字段一一对应设置该至少一个pathloss RS字段，其中，该至少一个pathloss RS字段中一个pathloss RS字段用于表示该至少一个pathloss RS中一个pathloss RS的ID。
应理解，由于pathloss RS字段用于表示pathloss RS的ID，所以每个pathloss RS字段的大小与pathloss RS的个数相关。可选地，该方法200还可以包括：该终端设备根据该至少一个pathloss RS字段的个数，确定该至少一个pathloss RS字段中每个pathloss RS字段的大小。例如，如图7和图9所示，假设该至少一个pathloss RS的最大个数为8，那么每个pathloss RS字段占用3比特；再例如，如图8所示，假设该至少一个pathloss RS的最大个数为16，那么每个pathloss RS字段占用4比特。
另外，该多个SRS resource set字段中每个SRS resource set字段用于指示是否需要更新或者激活对应的SRS resource set的pathloss RS，因此，每个SRS resource set字段可以设置为仅占用1bit。例如，若SRS resource set字段为“1”，则表示该SRS resource set字段为第一值，即该SRS resource set字段对 应的SRS resource set的pathloss RS需要更新或者激活，并且与该SRS resource set字段对应设置有pathloss RS字段，以表示更新或者激活的SRS resource set的pathloss RS的ID；若该SRS resource set字段为“0”，则表示该SRS resource set字段不为第一值，即该SRS resource set字段对应的SRS resource set的pathloss RS不需要更新或者激活。可选地，该多个SRS resource set字段中每个SRS resource set字段也可以设置为占用多个比特，本申请实施例并不限于此。
该第二个实施例中的MAC CE中的多个SRS resource set字段可以是连续的，或者也可以是不连续的。具体地，作为第一种情况，该多个SRS resource set字段可以是连续的，例如，该MAC CE可以包括SRS resource set位图，该多个SRS resource set字段为该SRS resource set位图包括的连续的多个比特位。
例如，如图7和图8所示，假设终端设备最多具有16个SRS resource set，那么对应的，该MCA CE包括的SRS resource set位图可以设置为16bits，即如图7和图8所示的Oct2和Oct3中的S 0至S 15，每个比特位对应表示一个SRS resource set字段，该MCA CE共包括16个SRS resource set字段。其中，该16个SRS resource set字段的排列顺序可以如图7或者8所示，或者也可以采用其它排列顺序，本申请实施例并不限于此，
对于该16个SRS resource set字段构成的位图中比特位的值为“1”的至少一个SRS resource set字段，在后面对应一一设置有至少一个pathloss RS字段，每个pathloss RS字段包括一个pathloss RS的ID，表示终端设备更新或者激活该pathloss RS。例如，假设S 3的值为“1”，那么与S 3对应的设置一个pathloss RS字段，该pathloss RS字段包括一个pathloss RS的ID，终端设备更新或者激活该S 3对应的SRS resource set的pathloss RS的ID。
相反的，对于该16个SRS resource set字段构成的位图中比特位的值为“0”的其它SRS resource set字段，可以不设置pathloss RS字段，或者也可以设置pathloss RS字段，但是终端设备并不需要激活或者更新其携带的pathloss RS的ID。
应理解，在该第一种情况中，如果不需要终端设备激活或者更新的pathloss RS不设置pathloss RS字段，即SRS resource set位图中某个比特位的值不为第一值时，不设置与之对应的pathloss RS字段，那么MAC CE的大小取决于终端设备需要更新或者激活的SRS resource set的pathloss RS个数。
可选地，作为另一种情况，该多个SRS resource set字段也可以是不连续的，例如，该MAC CE包括多个SRS resource set字段，另外，还包括多个pathloss RS字段，该多个pathloss RS字段与该多个SRS resource set字段一一对应。例如，该多个pathloss RS字段中第一pathloss RS字段对应于该多个SRS resource set字段中的第一SRS resource set字段，该第一pathloss RS字段与该第一SRS resource set字段连续，其中，第一SRS resource set字段为多个SRS resource set字段中的任意一个，第一pathloss RS字段为多个pathloss RS字段中与第一SRS resource set字段对应的一个字段。
第一SRS resource set字段用于指示终端设备是否激活或者更新对应的第一SRS resource set的第一pathloss RS，该第一pathloss RS字段用于表示该第一pathloss RS的ID，即该第一pathloss RS对应于该第一SRS resource set字段对应的第一SRS resource set。
在这种情况下，MAC CE的大小取决于网络设备为终端设备配置的SRS resource set的个数，如果SRS resource set的个数固定，那么MAC CE的大小固定。
例如，如图9所示，假设终端设备最多具有16个SRS resource set，那么MAC CE可以设置有16个SRS resource set字段，并分别表示为图9所示的S 0至S 15，每个SRS resource set字段对应有一个pathloss RS字段，即该MAC CE有16个pathloss RS字段。若该16个SRS resource set字段中的某个SRS resource set字段为“1”，例如假设S 1为“1”，则终端设备获取该S 1之后的一个pathloss RS字段中的pathloss RS的ID，并且该ID指示的pathloss RS为该终端设备需要更新或者激活的S 1对应的SRS resource set的pathloss RS。相反的，若某个该SRS resource set字段不为“1”，例如假设S 2为“0”，则表示该S 2对应的SRS resource set的pathloss RS不需要更新或者激活。
可选地，作为第三个实施例，仍然以该MAC CE包括至少一个SRS resource set字段和至少一个pathloss RS字段为例，但是与前两个实施例不同的是，这里假设网络设备为该终端设备配置的多个SRS resource set中不存在多个SRS resource set对应同一个pathloss RS的情况，例如，多个SRS resource set一一对应多个pathloss RS，那么参照第二个实施例中设置多个SRS resource set字段的方式，也可以设置多个pathloss RS字段，例如，在第二个实施例中SRS resource set字段可以是位图，那么，在该第三个实施例中，pathloss RS也可以设置为位图。
具体地，该MAC CE可以包括多个pathloss RS字段，该多个pathloss RS字段一一对应于网络设备为终端设备配置的多个pathloss RS，每个pathloss RS字段用于指示是否需要更新或者激活对应的pathloss RS。例如，该多个pathloss RS字段可以为pathloss RS位图，该pathloss RS位图包括的多个比 特位一一对应于网络设备为终端设备配置的多个pathloss RS，该pathloss RS位图中的每一个比特位用于指示是否需要更新或者激活对应的pathloss RS，也就是说，若该多个pathloss RS字段中某个pathloss RS字段为第一值，那么该pathloss RS字段属于上述S210中的至少一个pathloss RS字段，即该pathloss RS字段对应的SRS resource set的pathloss RS需要更新或者激活；相反的，如果该多个pathloss RS字段中某个pathloss RS字段不等于该第一值，那么该pathloss RS字段就不属于上述S210中的至少一个pathloss RS字段，即该pathloss RS字段对应的SRS resource set的pathloss RS不需要更新或者激活。
网络设备可以为终端设备配置多个pathloss RS，与之一一对应设置有多个pathloss RS字段，该多个pathloss RS字段中可能存在部分或者全部字段属于至少一个pathloss RS字段，在该MAC CE中，与该至少一个pathloss RS字段一一对应设置至少一个SRS resource set字段，其中，该至少一个SRS resource set字段中一个SRS resource set字段用于表示该至少一个SRS resource set中一个SRS resource set的标识。
应理解，由于SRS resource set字段用于表示SRS resource set的ID，所以每个SRS resource set字段的大小与SRS resource set的个数相关。可选地，该方法200还可以包括：该终端设备根据该至少一个SRS resource set的个数，确定该至少一个SRS resource set字段中每个SRS resource set字段的大小。例如，如图10和图11所示，假设该至少一个SRS resource set的最大个数为16，那么每个SRS resource set字段占用4比特。
另外，该多个pathloss RS字段中每个pathloss RS字段用于指示是否需要更新或者激活对应的SRS resource set的pathloss RS，因此，每个pathloss RS字段可以设置为仅占用1bit。例如，若某个pathloss RS字段为“1”，则表示该pathloss RS字段为第一值，那么在该MAC CE中设置有与该pathloss RS字段对应的SRS resource set字段，该SRS resource set字段包括SRS resource set的ID，该ID表示的SRS resource set的pathloss RS需要更新或者激活；若该pathloss RS字段为“0”，则表示该pathloss RS字段不为第一值，即该pathloss RS字段对应的SRS resource set的pathloss RS不需要更新或者激活。可选地，该多个pathloss RS字段中每个pathloss RS字段也可以设置为占用多个比特，本申请实施例并不限于此。
应理解，类似该第二个实施例中的MAC CE，在该第三个实施例中，MAC CE中的多个pathloss RS字段可以是连续的，或者也可以是不连续的。具体地，这里以该多个SRS resource set字段是连续的为例进行说明，即该MAC CE可以包括pathloss RS位图，该多个pathloss RS字段为该pathloss RS位图包括的连续的多个比特位。
例如，如图10所示，假设终端设备最多具有16个pathloss RS，并且该16个pathloss RS一一对应有16个SRS resource set，那么对应的，该MCA CE包括的pathloss RS位图可以设置为16bits，即如图10所示的Oct2和Oct3中的S 0至S 15，每个比特位对应表示一个pathloss RS字段，该MCA CE共包括16个pathloss RS字段。或者，如图11所示，假设终端设备最多具有8个pathloss RS，并且该8个pathloss RS一一对应有8个SRS resource set，那么对应的，该MCA CE包括的pathloss RS位图可以设置为8bits，即如图11所示的Oct2中的S 0至S 7，每个比特位对应表示一个pathloss RS字段，该MCA CE共包括8个pathloss RS字段。
可选地，16个pathloss RS字段的排列顺序可以如图10所示，8个pathloss RS字段的排列顺序可以如图11所示，或者也可以采用其它排列顺序，本申请实施例并不限于此，
如图10或者图11所示，对于该16个或者8个pathloss RS字段构成的位图中比特位的值为“1”的至少一个pathloss RS字段，在后面对应一一设置有至少一个SRS resource set字段，每个SRS resource set字段包括一个SRS resource set的ID，表示终端设备更新或者激活该SRS resource set对应的pathloss RS。例如，假设S 3的值为“1”，那么与S 3对应的设置一个SRS resource set字段，该SRS resource set字段包括一个SRS resource set的ID，终端设备更新或者激活该SRS resource set的pathloss RS的ID为S 3对应的pathloss RS。
相反的，对于该16个或者8个pathloss RS字段构成的位图中比特位的值为“0”的其它pathloss RS字段，可以不设置SRS resource set字段，或者也可以设置SRS resource set字段，但是终端设备并不需要激活或者更新该SRS resource set字段指示的SRS resource set的pathloss RS的ID。
应理解，在该这种设置pathloss RS位图的情况中，如果不需要终端设备激活或者更新某个SRS resource set的pathloss RS，那么就不设置SRS resource set字段，即pathloss RS位图中某个比特位的值不为第一值时，不设置与之对应的SRS resource set字段，那么MAC CE的大小取决于终端设备需要更新或者激活的SRS resource set的pathloss RS个数。
应理解，MAC CE中的多个pathloss RS字段也可以是不连续的，具体可参考第二个实施例中的第二种情况进行设置，为了简洁，在此不再赘述。
可选地，作为第四个实施例，仍然以该MAC CE包括至少一个SRS resource set字段和至少一个 pathloss RS字段为例，但是与前三个实施例不同的是，该MAC CE包括的该至少一个SRS resource set字段与该至少一个pathloss RS字段一一对应，其中，每个pathloss RS字段均为pathloss RS位图。具体地，假设第一pathloss RS字段为多个pathloss RS字段中的任意一个，第一SRS resource set字段为多个SRS resource set字段中的任意一个，并且，该第一SRS resource set字段对应于第一pathloss RS字段。该第一SRS resource set字段用于表示该至少一个SRS resource set中的第一SRS resource set的ID，该第一pathloss RS字段为一个位图，这里称为第一pathloss RS位图，该第一pathloss RS位图包括的多个比特位一一对应于为该终端设备配置的多个pathloss RS，该第一pathloss RS位图中存在一个或者多个第一比特位满足：该第一比特位的值为第一值，该第一比特位对应的pathloss RS为该第一SRS resource set对应的pathloss RS。
应理解，由于SRS resource set字段用于表示SRS resource set的ID，所以每个SRS resource set字段的大小与SRS resource set的个数相关。可选地，该方法200还可以包括：该终端设备根据该至少一个SRS resource set的个数，确定该至少一个SRS resource set字段中每个SRS resource set字段的大小。例如，如图12所示，假设该至少一个SRS resource set的最大个数为16，那么每个SRS resource set字段占用4比特。
应理解，该MAC CE包括的至少一个pathloss RS位图中每个位图的比特位的总个数由终端设备具有的pathloss RS个数决定。例如，若pathloss RS最大个数为8，则每个pathloss RS位图具有8个比特位；若pathloss RS的最大个数为16，则每个pathloss RS位图具有16个比特位。
例如，如图12所示，该MAC CE包括至少一个SRS resource set字段，每个SRS resource set字段包括一个SRS resource set的ID，以用于指示终端设备需要激活或者更新至少一个SRS resource set对应的pathloss RS。对于至少一个SRS resource set字段中任意一个SRS resource set字段，例如，以Oct2中的SRS resource set字段为例，这里将其称为第一SRS resource set字段，该第一SRS resource set字段包括第一SRS resource set的ID，与该第一SRS resource set字段对应的为第一pathloss RS字段，该第一pathloss RS字段为一个位图，这里称其为第一pathloss RS位图，并假设终端设备具有8个pathloss RS，即如图12中的Oct3所示，该第一pathloss RS位图具有8个比特位，每个比特位对应表示一个pathloss RS。
假设该第一SRS resource set字段对应的第一pathloss RS位图中仅有S 5的值为“1”，即第一值为“1”，第一pathloss RS位图中其余比特位均为“0”，那么表示该第一SRS resource set字段指示的第一SRS resource set对应的pathloss RS为S 5，并且终端设备激活或者更新该SRS resource set对应的pathloss RS的ID为S 5。
可选地，该MAC CE中包括的至少一个SRS resource set字段以及对应的pathloss RS字段的排列方式可以如图12所示，或者，也可以采用其他方式进行设置，本申请实施例并不限于此。
在上述四个实施例中，MAC CE中都包括SRS resource set字段和pathloss RS字段这两类字段，但该MAC CE也可以只包括SRS resource set字段和pathloss RS字段中的一类。
可选地，作为第五个实施例，该MAC CE可以包括pathloss RS字段，但不包括SRS resource set字段。具体地，该MAC CE可以包括多个pathloss RS字段，该多个pathloss RS字段一一对应于为该终端设备配置的多个SRS resource set以及pathloss RS。由于通常情况下，一个SRS resource set仅对应一个pathloss RS，因此，可以按照为终端设备配置的多个SRS resource set的某个特定顺序，排列与之对应的多个pathloss RS字段，那么该多个pathloss RS字段中一个pathloss RS字段用于表示对应的SRS resource set的pathloss RS的ID；另外，该方法200还可以包括：该终端设备根据该多个pathloss RS字段中每个pathloss RS字段指示的pathloss RS的ID，确定是否更新或者激活该每个pathloss RS字段对应的SRS resource set的pathloss RS。
可选地，考虑到可能存在多个SRS resource set对应同一个pathloss RS的情况，因此，可能存在多个pathloss RS字段包括的pathloss RS的ID相同，即该多个pathloss RS字段对应的多个SRS resource set对应同一个pathloss RS。
应理解，由于每个pathloss RS字段包括pathloss RS的ID，所以每个pathloss RS字段的大小与pathloss RS的个数相关。可选地，该方法200还可以包括：该终端设备根据该至少一个pathloss RS字段的个数，确定该至少一个pathloss RS字段中每个pathloss RS字段的大小。例如，假设该至少一个pathloss RS的最大个数为8，那么每个pathloss RS字段占用3比特；再例如，如图13所示，假设该至少一个pathloss RS的最大个数为16，那么每个pathloss RS字段占用4比特。
具体地，以图13为例，按照终端设备具有的多个SRS resource set对应设置多个pathloss RS字段，每个pathloss RS字段对应一个SRS resource set，并且每个pathloss RS字段包括其对应的SRS resource set的pathloss RS的ID，那么终端设备可以根据每个pathloss RS字段中包括的pathloss RS的ID，确定每 个SRS resource set对应的pathloss RS是否需要更新或者激活。例如，假设某个SRS resource set对应的pathloss RS字段包括的pathloss RS的ID改变，则表示终端设备需要激活该pathloss RS字段对应的SRS resource set的pathloss RS。
可选地，作为第六个实施例，该MAC CE还可以包括SRS resource set字段，但不包括pathloss RS字段。具体地，这里假设网络设备为该终端设备配置的多个SRS resource set中不存在不同SRS resource set对应同一个pathloss RS的情况，例如，多个SRS resource set一一对应多个pathloss RS，那么该MAC CE可以包括多个SRS resource set字段，该多个SRS resource set字段一一对应于为该终端设备配置的多个SRS resource set以及pathloss RS。
由于一个pathloss RS仅对应一个SRS resource set，因此，可以按照为终端设备配置的多个pathloss RS的某个特定顺序，排列与之对应的多个SRS resource set字段，那么该多个SRS resource set字段中一个SRS resource set字段用于表示对应的SRS resource set的ID；另外，该方法200还可以包括：该终端设备根据该多个SRS resource set字段中每个SRS resource set字段指示的SRS resource set的ID，确定是否更新或者激活该每个SRS resource set字段对应的SRS resource set的pathloss RS。
可选地，假设存在多个pathloss RS对应同一个SRS resource set的情况，那么可能存在多个SRS resource set字段包括的SRS resource set的ID相同，即该多个SRS resource set字段对应的多个pathloss RS对应同一个SRS resource set。
应理解，由于SRS resource set字段用于表示SRS resource set的ID，所以每个SRS resource set字段的大小与SRS resource set的个数相关。可选地，该方法200还可以包括：该终端设备根据该至少一个SRS resource set的个数，确定该至少一个SRS resource set字段中每个SRS resource set字段的大小。例如，如图14所示，假设该至少一个SRS resource set的最大个数为16，那么每个SRS resource set字段占用4比特。
具体地，以图14为例，按照终端设备具有的多个pathloss RS对应设置多个SRS resource set字段，每个SRS resource set字段对应一个pathloss RS，并且每个SRS resource set字段包括其对应的SRS resource set的ID，那么终端设备可以根据每个SRS resource set字段中包括的SRS resource set的ID以及每个SRS resource set字段对应的pathloss RS，确定每个SRS resource set对应的pathloss RS是否需要更新或者激活。例如，假设某个pathloss RS对应的SRS resource set字段包括的SRS resource set的ID改变，则表示终端设备需要激活该SRS resource set字段对应的SRS resource set的pathloss RS。
因此，本申请实施例的激活或者更新探测参考信号对应的路损参考信号的方法，可以灵活设置多种不同的MAC CE格式，并基于该MAC CE激活或更新SRS resource set的pathloss RS ID，使得传输时延大大降低。
应理解，在本申请的各种实施例中，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。
