Description

一种媒体接入访问MAC信令适用时间的确定方法和装置 技术领域
本申请涉及通信技术领域，尤其涉及一种媒体接入访问MAC信令适用时间的确定方法和装置。
背景技术
在通信系统中，网络设备可以通过物理下行共享信道(physical downlink shared channel，PDSCH)承载媒体接入控制层(media access control，MAC)信令通知用户终端(user equipment，UE)执行某特定过程。其中，UE适用MAC信令的具体时刻与UE发送承载该MAC信令的PDSCH的混合自动重传请求(hybrid automatic repeat request，HARQ)确认信息(acknowledge character，ACK)的时隙紧密关联。比如，当UE收到PDSCH所承载的MAC信令时，UE可以根据调度该PDSCH的DCI所指示的发送HARQ-ACK的时隙k 1，在时隙

后的第一个时隙应用MAC信令。
但是，在第三代合作伙伴计划(3 rd generation partnership project，3GPP)中，引入了基于NR的非授权频谱接入(NR-based access to unlicensed spectrum，NR-U)。在NR-U中，由于使用了非授权频谱，在所在频谱的发送信息前需要对所在频谱进行空闲信道评估(clear channel assessment，CCA)或对所在频谱先听后说(listen before talk，LBT)。在CCA或LBT成功后，在信道占用时间(channel occupancy time，COT)内可以发送信息。
如果CCA或LBT失败，UE则无法发送信息。考虑在NR-U中UE可能因为CCA或LBT失败无法发送信息，从而无法发送HARQ-ACK，因此在NR-U中对HARQ过程进行了相关的增强。其中，DCI中指示发送HARQ-ACK的时隙k 1在NR-U中可以配置为-1，用来表示UE延迟反馈本次HARQ，具体的HARQ反馈时刻由后续DCI决定。
因此，在NR-U中，针对PDSCH承载的各种MAC信令，如果调度该PDSCH的DCI中所指示的发送HARQ-ACK时隙k 1被配置为-1，UE不能根据现有的方式处理得到MAC信令的适用时间。因此，此时MAC信令的适用时间并不明确，网络设备和UE会产生不同的理解，可能会影响通信系统的性能及灵活性。

具体实施方式
以下，对本申请实施例涉及的名词进行解释。
1)、MAC信令的适用时间，是指MAC信令中指示的命令的适用时间。例如，如果MAC信令指示SCell激活，则MAC信令的适用时间可以是指SCell激活的时间。又例如，如果MAC信令指示半静态信道状态信息(channel state information reference signal，CSI)物理上行共享信道(physical uplink shared channel，PUSCH)上报配置生效，则MAC信令的适用时间可以是指半静态CSI PUSCH上报配置生效的时间。
2)、适用的值，在NR-U场景中，网络设备指示发送HARQ-ACK的第一值被配置为除-1以外的值时，该第一值可以认为是适用的值。
3)、不适用的值，在NR-U场景中，网络设备指示发送HARQ-ACK的第一值被配置为-1时，该-1可以认为不适用的值。
4)、本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，其它量词与之类似。“和/或”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。此外，对于单数形式“a”，“an”和“the”出现的元素(element)，除非上下文另有明确规定，否则其不意味着“一个或仅一个”，而是意味着“一个或多于一个”。例如，“a device”意味着对一个或多个这样的device。再者，至少一个(at least one of).......”意味着后续关联对象中的一个或任意组合，例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC，或ABC。
在现有通信系统中，网络设备可以通过物理下行共享信道(physical downlink shared channel，PDSCH)承载媒体接入控制层(media access control，MAC)控制信令通知UE执行某特定过程。
例如，网络设备可以通过MAC信令激活辅小区(Secondary cell，SCell)，其流程可以如下所示：
UE在时隙(slot)n收到PDSCH承载的SCell激活命令，UE可以在时隙n+k适用SCell激活的操作。比如，UE可以在时隙n+k启动SCell去激活定时器(deactivation timer)以及上报信道状态信息(channel state information)。其中,
Figure PCTCN2021071921-appb-000002
k 1是UE收到的下行控制信息(downlink control information，DCI)中所指示的混合自动重传请求(hybrid automatic repeat request，HARQ)的时隙(PDSCH-to-HARQ_feedback timing  indicator)。其中，μ是子载波间隔配置，
Figure PCTCN2021071921-appb-000003
为子载波间隔配置μ为时每个子帧中的时隙数量。HARQ反馈可以是指发送PDSCH的HARQ确认信息(acknowledge character，ACK)。
又例如，网络设备也可以通过PDSCH承载的MAC信令，激活或去激活半静态信道状态信息参考信号(semi-persistent channel state information reference signal，SP CSI-RS)。其流程可以如下所示：
如果UE收到SP CSI-RS激活命令，DCI指示UE在时隙n发送承载SP CSI-RS激活命令的PDSCH的HARQ-ACK。UE可以认为SP CSI-RS的配置在时隙
Figure PCTCN2021071921-appb-000004
后的第一个时隙生效。
同理，对于被配置半静态探测参考信号(sounding reference signal，SRS)资源集的UE，网络设备可以通过PDSCH承载的激活命令激活半静态SRS资源集，DCI指示UE可以在时隙n发送该PDSCH的HARQ-ACK。UE可以认为半静态SRS资源集的配置从时隙
Figure PCTCN2021071921-appb-000005
后的第一个时隙开始生效。
除前述的SCell激活或去激活，SP CSI-RS激活或去激活和SP-SRS激活或去激活，网络设备还可以通过PDSCH承载MAC信令通知UE执行非周期CSI-RS激活或去激活，和(transmission configuration indicator，TCI)激活。
目前，对PDSCH承载的各种MAC信令的描述中，UE适用MAC信令的具体时刻与UE发送承载该MAC信令的PDSCH的HARQ-ACK时刻紧密关联。比如，当UE收到PDSCH所承载的MAC信令时，UE可以根据调度该PDSCH的DCI所指示的发送HARQ-ACK的时隙k 1，在时隙
Figure PCTCN2021071921-appb-000006
后的第一个时隙应用MAC信令。
但是，在第三代合作伙伴计划(3 rd generation partnership project，3GPP)中，引入了基于NR的非授权频谱接入(NR-based access to unlicensed spectrum，NR-U)。在NR-U中，由于使用了非授权频谱，在所在频谱的发送信息前需要对所在频谱进行空闲信道评估(clear channel assessment，CCA)或对所在频谱先听后说(listen before talk，LBT)。在CCA或LBT成功后，在信道占用时间(channel occupancy time，COT)内可以发送信息。
如果CCA或LBT失败，UE则无法发送信息。考虑在NR-U中UE可能因为CCA或LBT失败无法发送信息，从而无法发送HARQ-ACK，因此在NR-U中对HARQ过程进行了相关的增强。其中，DCI中指示发送HARQ-ACK的时隙k 1在NR-U中可以配置为-1，用来表示UE延迟反馈本次HARQ，具体的HARQ反馈时刻由后续DCI决定。
因此，在NR-U中，针对PDSCH承载的各种MAC信令，如果调度该PDSCH的DCI中所指示的发送HARQ-ACK时隙k 1被配置为-1，UE不能根据现有的方式处理得到MAC信令的适用时间。因此，此时MAC信令的适用时间并不明确，网络设备和UE会产生不同的理解，因此可能会影响通信系统的性能及灵活性。
基于上述问题，本申请实施例提供了一种MAC信令适用时间的确定方法。该方法中，在发送承载MAC信令的PDSCH的HARQ-ACK时隙k 1被配置为不适用的值，如-1时，终端设备可以根据该不适用的值，确定MAC信令的适用时间。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统，未来的第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，及未来的通信系统，如6G系统等。

本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或传输接收点(Transmission and Reception Point,TRP)，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。或者是，在以UE为中心的网络中，多个网络侧设备，如小站，可以有独立的控制器，如分布式控制器，各小站能够独立调度用户，小站之间在长期上存在交互信息，使得在为UE提供协作服务时，也能够有一定的灵活性。

Figure PCTCN2021071921-appb-000007
适用，或者终端设备可以确定MAC信令所指示的操作在时隙
Figure PCTCN2021071921-appb-000008
适用。终端设备可以确定在时隙
Figure PCTCN2021071921-appb-000009
启动SCell Deactivation Timer。
可选的，终端设备可以在时隙a+m发送HARQ-ACK。
另一种可能的实现方式中，如果DCI中发送HARQ-ACK的第一值m被配置为不适用的值，如-1，那么终端设备延迟发送HARQ-ACK。但是，终端设备无法根据上述方法准确的确定MAC信令的适用时间。
在一个示例中，终端设备不期待DCI中的第一值被配置如-1等不适用的值。网络设备发送给终端设备的DCI中的第一值不能被配置为如-1等不适用的值，也即DCI中的第一值指示终端设备不延迟反馈HARQ-ACK。因此，网络设备发送给终端设备DCI中的第一值均会被配置为适用的值，第一值也可以用于指示终端设备发送HARQ-ACK的时间。终端设备可以根据第一值，确定MAC信令的适用时间。
基于上述方案，可以预先定义网络设备向终端设备发送的DCI中的发送HARQ-ACK的第一值不会被配置为不适用的值，因此终端设备与网络设备可以根据第一值，确定MAC信令的适用时间，网络设备与终端设备可以对齐对MAC信令的适用时间的理解。
另一个示例中，如果DCI中的第一值指示终端设备延迟反馈发送HARQ-ACK，终端设备可以根据以下方式1-方式4，确定MAC信令的适用时间。以下，分别介绍方式1-方式4。
方式1：终端设备根据第二值，确定MAC信令的适用时间。
这里的第二值可以是通信性协议规定的，或者是网络设备指示的。该第二值与承载MAC信令的PDSCH的子载波间隔和终端设备对PDSCH的处理能力中的至少一个是相关的。
在一种可能的实现方式中，第二值可以是基于终端设备对PDSCH的处理能力确定的。基于终端设备对PDSCH的处理能力可以确定出终端设备有能力发送PDSCH的HARQ-ACK的第一个时隙。该第二值可以用于指示第一个时隙，或者可以用于指示第一个时隙之后的一个时隙。这里的有能力发送PDSCH的HARQ-ACK的时隙可以是指如果终端设备要发送PDSCH的HARQ-ACK，可以在该时隙开始发送HARQ-ACK。但是由于第一值指示终端设备延迟反馈HARQ-ACK，因此终端设备本次不发送HARQ-ACK。
其中，参见标准3GPP TS 38.214.V16.3.0(2020-09)中5.3节的描述，终端设备有能力发送PDSCH的HARQ-ACK的第一个时隙应该不早于时域符号L1。该时域符号L1可以是与上述PDSCH的最后一个时域符号间隔T之后的第一个上行符号。可选的，这里的第一个上行符号需要考虑L1的CP。
T＝(N1+d 1,1+d 2)(2048+144)·κ·2 -μ·T c+Text。
上述公式中，N1是子载波间隔配置μ确定的PDSCH解码时间。N1以时域符号为单位。T c是时间单元。T c可以根据以下公式确定。
Figure PCTCN2021071921-appb-000010
Δf max＝480·10 3Hz，N f＝4096，Text可以理解为循环前缀(cyclic prefix，CP)扩展(extension)有关的时间。d 1,1是通信协议规定的，可以根据PDSCH处理能力、PDSCH 映射类型、PDSCH符号位置、以及PDSCH与控制资源集(control-resource set，CORESET)位置关系确定的。d 2是在PUCCH有高优先级，且PUCCH与低优先级的PUCCH或PUSCH重合时终端设备上报的值，其他区情况d 2＝0。
由于终端设备对PDSCH的处理能力越快或者越强，确定出的终端设备有能力发送HARQ-ACK的时隙就越早，因此第二值可以越小。终端设备对PDSCH的处理能力越慢或者越弱，确定出的终端设备有能力发送HARQ-ACK的时隙就越晚，因此第二值可以越大。
另一个可能的实现方式中，第二值可以是根据PDSCH的子载波间隔确定的。其中，如果PDSCH的子载波间隔越大，当前子载波间隔下的时隙数量就越多，第二值可以越大。PDSCH的子载波间隔越小，当前子载波间隔下的时隙数量就越小，因此第二值可以越小。
基于以上原因，可以预先设置第二值与终端设备对PDSCH的处理能力的对应关系。或者，也可以预先设置第二值与PDSCH的子载波间隔的对应关系。或者，也可以预先设置第二值与终端设备对PDSCH的处理能力、PDSCH的子载波间隔的三方关系。终端设备可以根据自身对PDSCH的处理能力和/或PDSCH的子载波间隔确定第二值，继而确定MAC信令的适用时间。
可选的，第二值也可以与其他信息相关，本申请不做具体限定。
本申请实施例中，每一个终端设备可以基于自身对PDSCH的处理能力和/或PDSCH的子载波间隔确定第二值。或者，在DCI中的第一值指示延迟反馈HARQ-ACK时，所有的终端设备可以使用相同的第二值。
在一个示例中，终端设备可以基于第二值代替第一值，采用通信协议规定的方式，确定MAC信令的适用时间。举例来说，UE收到SP CSI-RS激活命令，DCI指示中的m指示终端设备延迟反馈HARQ-ACK。终端设备可以认为SP CSI-RS的配置在
Figure PCTCN2021071921-appb-000011
后的第一个时隙生效。X是第二值。
另一个示例中，第二值可以指示MAC信令的适用时间。终端设备可以基于第二值确定MAC信令的适用时间。例如，终端设备接收SP CSI-RS激活命令，DCI指示中的m指示终端设备延迟反馈HARQ-ACK。终端设备可以认为SP CSI-RS的配置在第二值所指示的时隙生效。
基于上述方案，由于终端设备可以确定自身对PDSCH的处理能力，且终端设备也可以确定PDSCH的子载波间隔。因此，如果终端设备接收到的DCI中第一值指示延迟反馈HARQ-ACK，终端设备可以根据自身对PDSCH的处理能力和/或PDSCH的子载波间隔，确定第二值，继而确定MAC信令的适用时间。
以下，结合附图3介绍本申请实施例提供的方式1。
参阅附图3，终端设备接收来自网络设备的DCI1，该DCI1用于调度承载MAC1的PDSCH1。终端设备在DCI1指示的时隙a接收来自网络设备的PDSCH1，获取MAC1。DCI1中的第一值m指示终端设备延迟发送HARQ-ACK。MAC1指示终端设备激活SCell。终端设备可以基于DCI1指示的时频资源，接收PDSCH1，获取MAC1。终端设备可以确定第二值b，继而确定在时隙

启动SCell去激活定时器。或者，终端设备可以确定在时隙b，启动SCell去激活定时器。可选的，终端设备可以在时隙
Figure PCTCN2021071921-appb-000013
之后的任一个时隙，或者时隙b之后的任一个时隙启动SCell去激活定时器。
可选的，由于DCI中的第一值指示终端设备延迟反馈HARQ-ACK，因此终端设备可 以基于后续的接收到的DCI，发送PDSCH1的HARQ-ACK。比如，终端设备接收来自网络设备的DCI2，DCI2用于调度PDSCH2。DCI2可以用于确定发送PDSCH1的HARQ-ACK的时隙。
方式2：终端设备基于网络设备指示的第三值，确定MAC信令的适用时间。
这里的第三值可以是与MAC信令一起指示的。在一个示例中，网络设备可以在MAC信令中指示该第三值。举例来说，网络设备可以在MAC信令中携带该第三值，或者网络设备可以在MAC信令中以一个比特序列指示该第三值。其中，比特序列的取值与该第三值的关系可以是网络设备发送给终端设备的，也可以是通信协议规定的。或者，网络设备可以在MAC信令中以一个标识指示该第三值。其中，标识与该第三值的关系可以是网络设备发送给终端设备的，也可以是通信协议规定的。
可选的，该第三值也可以是与MAC信令分开指示的。在一个示例中，网络设备可以在DCI中指示该第三值。其中，在DCI中指示该第三值的方式，可以参见如上述在MAC信令指示该第三值的方式，此处不再赘述。
另一个示例中，网络设备可以通过无线资源控制(radio resource control，RRC)消息向终端设备指示该第三值。比如，RRC重配置(RRC Reconfiguration)消息、或者RRC建立(RRC Set up)消息，或者RRC重建里(RRC Reestablishment)消息。网络设备可以同时发送携带有第三值的RRC消息和上述MAC信令，或者可以先发送携带有第三值的RRC消息再发送上述MAC信令，或者可以先发送上述MAC信令再发送携带有第三值的RRC消息。
举例来说，网络设备可以在终端设备的初始接入过程中，通过RRC消息向终端设备该第三值，向终端设备指示如果DCI中的第一值指示延迟反馈HARQ-ACK，终端设备可以基于该第三值，确定MAC信令的适用时间。
在一个示例中，终端设备可以基于第三值代替第一值，采用通信协议规定的方式，确定MAC信令的适用时间。举例来说，UE收到SP CSI-RS激活命令，DCI指示中的m指示终端设备延迟反馈HARQ-ACK。终端设备可以认为SP CSI-RS的配置在
Figure PCTCN2021071921-appb-000014
后的第一个时隙生效。X是第三值。
另一个示例中，第三值可以指示MAC信令的适用时间。终端设备可以基于第三值确定MAC信令的适用时间。例如，终端设备接收SP CSI-RS激活命令，DCI指示中的m指示终端设备延迟反馈HARQ-ACK。终端设备可以认为SP CSI-RS的配置在第三值所指示的时隙生效。
需要说明的是，网络设备指示的第三值可以是通过方式1中第二值的确定方式确定的。比如，网络设备可以根据终端设备对PDSCH的处理能力和/或PDSCH的子载波间隔确定第三值。其中，第三值与第二值的区别是，由网络设备为终端设备配置第三值，可以更加灵活，可以充分考虑网络设备以及终端设备当前处理的通信数据。
基于上述方案，在DCI中的第一值指示终端设备延迟反馈HARQ-ACK时，网络设备可以向终端设备发送第三值，用来让终端设备确定MAC信令的适用时间，让终端设备在该适用时间执行MAC信令指示的相关操作。网络设备与终端设备可以对齐对MAC信令的适用时间的理解，还可以提高通信系统的灵活性。
以下，结合图3介绍本申请实施例提供的方式2。
终端设备在随机接入过程接收来自网络设备的第三值p。终端设备接收来自网络设备的DCI1，该DCI1用于调度承载MAC1的PDSCH1。终端设备在DCI1指示的时隙n接收来自网络设备的PDSCH1，从而获得MAC1。该MAC1指示终端设备激活SCell。终端设备可以基于DCI1指示的时频资源，接收MAC1。该DCI1中的第一值指示终端设备延迟反馈HARQ-ACK。终端设备可以在时隙

启动SCell去激活定时器。或者，终端设备可以在时隙p，启动SCell去激活定时器。可选的，终端设备可以在时隙
Figure PCTCN2021071921-appb-000016
之后的任一个时隙，或时隙p之后的任一个时隙，启动SCell去激活定时器。
可选的，由于DCI1中的第一值指示终端设备延迟反馈HARQ-ACK，因此终端设备可以确定延迟反馈本次PDSCH1的HARQ-ACK。终端设备可以基于后续的接收到的DCI，反馈PDSCH1的HARQ-ACK。比如，终端设备接收来自网络设备的DCI2，DCI2用来调度PDSCH2。DCI2可以用于确定发送PDSCH1的HARQ-ACK的时隙。
方式3：终端设备根据对PDSCH的处理能力，确定MAC信令的适用时间。
在一种可能的实现方式中，基于终端设备对PDSCH的处理能力可以确定出终端设备有能力发送PDSCH的HARQ-ACK的第一时隙。该第一时隙可以是终端设备有能力发送PDSCH的HARQ-ACK的第一个时隙。终端设备可以基于第一时隙，或者第一时隙之后的一个时隙确定MAC信令的适用时间。其中，终端设备基于第一时隙还是基于第一时隙之后的一个时隙可以是通信协议规定的，或者也可以是网络设备指示的。可选的，终端设备基于第一时隙之后的哪一个时隙可以是通信协议规定的，或者也可以是网络设备指示的。比如，通信协议可以规定或者网络设备可以指示一个偏移k，该偏移k可以是指第一时隙之后的一个时隙针对第一时隙的偏移，k是大于等于0的整数。终端设备可以基于对PDSCH的处理能力确定的第一时隙以及偏移k，确定MAC信令的适用时间。
前述有能力发送PDSCH的HARQ-ACK的第一个时隙可以是指如果终端设备要发送PDSCH的HARQ-ACK，可以在该时隙开始发送HARQ-ACK。但是由于第一值指示终端设备延迟反馈HARQ-ACK，因此终端设备本次不发送HARQ-ACK。
其中，参见标准3GPP TS 38.214.V16.3.0(2020-09)中5.3节的描述，终端设备有能力发送PDSCH的HARQ-ACK的时隙应该不早于时域符号L1。该时域符号L1可以是与上述PDSCH的最后一个时域符号间隔T之后的第一个符号。可选的，这里的第一个上行符号需要考虑L1的CP。
T＝(N1+d 1,1+d 2)(2048+144)·κ·2 -μ·T c+Text。
上述公式中，N1是子载波间隔配置μ确定的PDSCH解码时间。N1以时域符号为单位。T c是时间单元。T c可以根据以下公式确定。
Figure PCTCN2021071921-appb-000017
Δf max＝480·10 3Hz，N f＝4096，Text可以理解为循环前缀(cyclic prefix，CP)扩展(extension)有关的时间。d 1,1是通信协议规定的，可以根据PDSCH处理能力、PDSCH映射类型、PDSCH符号位置、以及PDSCH与控制资源集(control-resource set，CORESET)位置关系确定的。d 2是在PUCCH有高优先级，且PUCCH与低优先级的PUCCH或PUSCH重合时终端设备上报的值，其他情况d 2＝0。
终端设备可以基于上述方法确定出第一时隙，确定MAC信令的适用时间。比如，可以根据该第一时隙代替DCI中的第一值，采用通信协议规定的公式，确定MAC信令的适用时间。或者，可以根据该第一时隙之后的一个时隙代替DCI中的第一值，采用通信协议规定的公式，确定MAC信令的适用时间。
基于上述方案，终端设备可以基于自身对PDSCH的处理能力，确定有能力发送PDSCH的HARQ-ACK的时隙，进而可以确定MAC信令的适用时间。网络设备和终端设备可以确定出相同的MAC信令的适用时间，对齐对MAC信令的适用时间的理解，并且可以节省传输资源。
以下，结合图3介绍本申请实施例提供的方式3。
终端设备接收来自网络设备的DCI1，该DCI1用于调度承载MAC1的PDSCH1。终端设备在DCI1指示的时隙1接收来自网络设备的PDSCH1，从而获得MAC1。该MAC1指示终端设备激活SCell。终端设备可以基于DCI1指示的时频资源，接收MAC1。该DCI1中的第一值指示终端设备延迟反馈HARQ-ACK。终端设备可以确定有能力发送PDSCH1的HARQ-ACK的时隙为时隙4，因此终端设备可以在时隙

启动SCell去激活定时器。可选的，通信协议规定MAC信令的适用时间与有能力发送PDSCH的HARQ-ACK的时隙的偏移为k，k是大于0的整数。终端设备可以基于有能力发送PDSCH1的时隙4以及偏移k，在时隙
Figure PCTCN2021071921-appb-000019
启动SCell去激活定时器。
可选的，由于DCI1中的第一值指示终端设备延迟反馈HARQ-ACK，因此终端设备可以确定延迟反馈本次PDSCH1的HARQ-ACK。终端设备可以基于后续的接收到的DCI，反馈PDSCH1的HARQ-ACK。比如，终端设备接收来自网络设备的DCI2，DCI2用来调度PDSCH2。DCI2可以用于确定发送PDSCH1的HARQ-ACK的时隙。
方式4：终端设备根据第三指示信息，确定MAC信令的适用时间。
其中，如果调度承载MAC信令的PDSCH的DCI中的第一值指示终端设备延迟反馈HARQ-ACK，那么终端设备可以不执行MAC信令指示的相关操作，等待后续的DCI。后续的DCI与前述的调度承载MAC信令的PDSCH的DCI，可以是调度承载MAC信令的PDSCH的DCI之后的DCI。
参阅图4，网络设备通过DCI1调度承载MAC1的PDSCH1，终端设备基于DCI1在时隙a接收到PDSCHA1，获取MAC1。该MAC1指示终端设备进行SCell去激活，由于DCI1中的第一值指示终端设备延迟反馈HARQ-ACK，因此终端设备可以暂时不确定SCell去激活的时间，直到终端设备接收到下一个DCI。比如，网络设备通过DCI2调度PDSCH2。DCI2中的第一值指示终端设备不延迟反馈HARQ-ACK，因此终端设备可以基于DCI2中的第一值确定SCell去激活的时间。
基于上述方案，在调度承载MAC信令的PDSCH的DCI中的第一值指示终端设备延迟反馈HARQ-ACK时，终端设备可以暂时不执行MAC信令的相关操作，等待后续的DCI。终端设备可以基于后续的DCI确定前述MAC信令的适用时间。
另外需要说明的是，由于网络设备与终端设备对于MAC信令的适用时间的理解需要对齐，因此网络设备也可以根据上述方式1-方式4确定MAC信令的适用时间。其中，网络设备使用的方式应该与终端设备使用的方式相同。
终端设备可以在确定的MAC信令的适用时间，执行MAC信令指示的操作。比如，MAC信令指示非周期CSI-RS上报配置激活，则终端设备可以在确定的MAC信令的适用时间，确定非周期CSI-RS的上报配置被激活，终端设备可以根据该非周期CSI-RS的上报配置上报CSI。或者，如果MAC信令指示半静态SRS资源集激活，则终端设备可以认为在确定的MAC信令的适用时间半静态SRS资源集的配置信息生效，终端设备可以基于该半静态SRS资源集的配置信息发送半静态SRS。
可选的，网络设备确定MAC信令的适用时间是为了终端设备可以在该MAC信令的适用时间能够执行相关操作。比如，MAC信令指示非周期CSI-RS上报配置激活，则终端设备可以在确定的MAC信令的适用时间，确定非周期CSI-RS的上报配置被激活。网络设备可以在确定的MAC信令的适用时间发送非周期CSI-RS资源，或者也可以在MAC信令的适用时间之前发送非周期CSI-RS资源，或者也可以在MAC信令的适用时间之后发送非周期CSI-RS资源，只要终端设备可以接收到非周期CSI-RS资源即可。
基于上述方案，如果在调度PDSCH的DCI中的第一值指示终端设备延迟反馈HARQ-ACK，终端设备可以根据上述方案确定出MAC信令的适用时间，因此可以对齐网络设备与终端设备对MAC信令的适用时间的理解，可以提高通信性能。
