下面对本申请实施例涉及的相关技术及术语进行介绍。
一、下行控制信息(downlink control information，DCI)与该DCI调度的物理上行共享信道(physical uplink shared channel，PUSCH)之间的时序关系
例如图3所示，gNB在下行(downlink，DL)时隙X向UE发送DCI，该DCI用于调度UE发送PUSCH，该DCI可以称为上行调度DCI。gNB还向UE指示DCI与PUSCH之间的时间间隔为KDCI-PUSCH。UE在DL时隙X接收该DCI，UE DL与gNB DL之间的信号传输时延为信号往返时间(round-trip time，RTT)的一半，即RTT/2，也就是说，相同时隙标识的UE DL时隙与gNB DL时隙间隔RTT/2的时长，如标识为X的UE DL的时隙X与gNB DL的时隙X之间间隔RTT/2的时长。UE确定在与UL时隙X之间的时间间隔为KDCI-PUSCH的UL时隙M发送DCI调度的PUSCH，该UL时隙M与UL时隙X之间的时间间隔为KDCI-PUSCH。而由于UE上行(uplink，UL)发送的信号传输至gNB UL接收信号的传输时延为RTT/2，因此，gNB在初始接入阶段会为UE配置一个UE UL的时间提前(time advance，TA)量，UE根据TA量将UL时隙提前，使得gNB能够在gNB UL时隙M接收到UE在时间提前后的UE UL时隙M发送的PUSCH。如图3所示，相同 时隙标识的UE UL时隙与gNB UL时隙之间间隔RTT/2的时长，如标识为X的UE UL的时隙X与gNB UL的时隙X间隔RTT/2的时长，标识为M的UE UL的时隙M与gNB UL的时隙M间隔RTT/2的时长。
本申请中，由于信号传输时延、设备的信号处理时延的影响，使得相同标识的时间单元(如时间单元可以是符号、微时隙、时隙、子帧或帧)在同一设备的上行和下行的绝对时间可能不同，如图3所示的UE UL时隙X与UE DL时隙X的绝对时间不同。以及相同标识的时间单元、且同一传输方向(如DL或UL)在不同设备的绝对时间可能不同，如图3所示的gNB DL时隙X与UE DL时隙X的绝对时间不同。
其中，上行调度DCI与PUSCH之间的时间间隔KDCI-PUSCH，KDCI-PUSCH的时长主要考虑了中UE的信息处理时延(如DCI的解调、解码等处理时间以及PUSCH的编码、调制等处理时间)以及DCI和PUSCH的传输时延。该KDCI-PUSCH可以是gNB通过该上行调度DCI中的指示域指示给终端设备的。或者，在移动通信系统中，由于NTN网络的基站与终端设备之间大距离带来的较长的传输时延，gNB在初始接入阶段之后可以通过媒体接入控制(medium access control，MAC)控制元素(control element，CE)为终端设备配置一个时间间隔Koffset，该Koffset适用于一段时间的上行调度和下行调度，以及gNB在上行调度DCI中指示一个K2，终端设备接收到该上行调度DCI后，可以确定该DCI与PUSCH之间的时间间隔KDCI-PUSCH＝Koffset+K2。
二、PDSCH与该PDSCH的反馈信息之间的时序关系
例如图4所示，gNB在DL时隙Y的PDSCH向UE发送下行数据，相应地，UE在UE DL时隙Y接收到该PDSCH承载的下行数据，其中，UE DL时隙与gNB DL时隙之间存在RTT/2的传输时延。gNB还向UE指示该PDSCH与该PDSCH的反馈信息之间的时间间隔为KPDSCH-HARQ。如反馈信息可以是混合自动重传请求(hybrid automatic repeat request，HARQ)中的确认(acknowledge，ACK)反馈信息(记作HARQ-ACK)或非确认(non-acknowledge，NACK)反馈信息(记作HARQ-NACK)。UE在UE UL时隙中与时隙Y之间的时间间隔为KPDSCH-HARQ的时隙N发送HARQ反馈信息，使得gNB在gNB UL时隙N上接收到UE的该HARQ反馈信息。
其中，与KDCI-PUSCH类似，KPDSCH-HARQ的时长主要考虑了中UE的信息处理时延(如PDSCH的解调、解码等处理时间以及HARQ的编码、调制等处理时间)以及PDSCH和HARQ的传输时延。该KPDSCH-HARQ可以是gNB通过调度该PDSCH的该下行调度DCI中的指示域指示给终端设备的。或者，当传输时延较长时，该KPDSCH-HARQ包括MAC CE配置的Koffset，以及下行调度DCI中指示的K1，即KPDSCH-HARQ＝Koffset+K1。
三、MAC CE
MAC CE是MAC层的控制信息，MAC CE可以包括用于承载调度相关信息的MAC CE以及用于承载随机接入相关信息的MAC CE。以及，MAC CE还用于通知终端设备配置信息的激活或去激活，如可以包括但不限于如下MAC CE：
1、配置激活上述终端设备专用Koffset的MAC CE
2、信道状态相关资源的激活或去激活MAC CE
如半静态(semi-persistent)信道状态信息参考信号(CSI-reference signal，CSI-RS)资源集合的激活或去激活MAC CE、半静态(semi-persistent)CSI-干扰测量(interference measurement，IM)资源集合的激活或去激活MAC CE、UE专用(UE-specific)PDSCH的 传输配置指示(transmission configuration indicator，TCI)状态的激活或去激活MAC CE、物理上行控制信道(physical uplink control channel，PUCCH)承载的SP CSI报告的激活或去激活MAC CE，以及，SP探测参考信号(sounding reference signal，SRS)激活或去激活MAC CE等。
3、非连续接收(discontinuous reception，DRX)相关的MAC CE
DRX命令MAC CE、长DRX命令MAC CE用于激活或去激活UE的非连续接收状态。
4、PUCCH空间关系(即波束配置)激活MAC CE
5、分组数据汇聚层协议(packet data convergence protocol，PDCP)重复的激活或去激活MAC CE
四、MAC CE的生效时间
MAC CE作为下行数据承载在PDSCH上，对于上述用于通知终端设备配置信息激活或去激活的MAC CE，考虑传输时延、终端设备的处理时延、配置生效准备时间，以及终端设备是否成功接收到该MAC CE等因素，定义了MAC CE的生效时间。
以MAC CE激活Koffset为例，如图5所示，终端设备在时隙Y中成功接收到承载MAC CE的PDSCH后，根据PDSCH与HARQ的时序关系，在与时隙Y间隔KPDSCH-HARQ的时隙发送HARQ反馈信息。若终端设备成功接收到该MAC CE，对于上行MAC CE，即用于激活上行配置的MAC CE，终端设备与网络设备认为该MAC CE激活的上行配置在上行时隙E生效，生效。其中，表示子载波间隔(sub-carrier spacing，SCS)＝2μ·15kHz时每个子帧对应的时隙个数，μ＝0、1、2、3、4。对于不同SCS，的时长均为3ms。对于下行MAC CE，即用于激活下行配置的MAC CE，终端设备与网络设备认为该MAC CE激活的下行配置在下行时隙E′生效，其中，Kmac是SCS为15kHz，即μ＝0时，gNB的上行时隙与下行时隙之间的偏移量，即同一时隙标识对应的下行时隙与上行时隙之间的偏移量，如时隙标识Y对应的下行时隙Y与上行时隙Y之间的偏移量为Kmac。
然而，以上对于MAC CE激活的上行配置的生效时间的定义可能出现因终端设备与网络设备理解不一致造成传输失败的问题。如图6所示，以μ＝0，MAC CE激活Koffset,1，Kmac＝1为例，gNB在DL时隙Y的PDSCH向UE发送用于激活Koffset,1的MAC CE，相应地，UE在UE DL时隙Y的PDSCH接收到该MAC CE，UE确定Koffset,1将被激活。终端设备基于PDSCH与HARQ反馈信息之间的时序关系，根据当前生效的Koffset,0和K1，确定在UL时隙N向网络设备发送HARQ-ACK。因此，UE基于发送HARQ-ACK的UL时隙N确定该MAC CE在UL时隙E开始生效，相应地，gNB在gNB的UL时隙N接收到来自UE的HARQ-ACK，gNB基于UL时隙N确定该MAC CE在UL时隙E开始生效。以及对于DL时隙，gNB和UE认为该MAC CE在DL时隙E'生效，若gNB在DL时隙P向UE发送DCI，该DCI用于调度UE发送上行数据。由于gNB还未接收到来自UE对激活Koffset,1的MAC CE的反馈信息，因此，Koffset,1还为生效，gNB基于当前生效的Koffset,0以及该DCI指示的K2，确定在时隙Q'的PUSCH接收UE响应于该上行调度DCI发送的上行数据，其中Q'＝P+Koffset,0+K2。而UE在DL时隙P接收到来自gNB的该上行调度DCI后，由于UE上行时隙中该Koffset,1已生效，则UE基于Koffset,1以及该DCI指示的K2，确定在时隙Q的 PUSCH发送上行数据，其中Q＝P+Koffset,1+K2。这使得由于MAC CE生效时间的理解不一致，使得UE与gNB对发送上行数据的时隙未达成一致，造成调度失败的情况。
针对上述图6所示的问题，目前存在一种方案，如图7所示，由于gNB能够获知gNB和UE的同一时隙标识对应的DL时隙与UL时隙之间的偏移量，即Kmac和TA，以及能够获知gNB与UE之间的信号往返时间RTT，因此，gNB能够确定若UE正确接收MAC CE，该MAC CE将在UE的UL时隙E生效，该UL时隙E对应UE的DL时隙P，而gNB在DL时隙P认为MAC CE还未生效，则从DL时隙P开始gNB向UE发送的调度信息将出现理解不一致的情况。在DL时隙P之前的T1时间段gNB与UE均认为MAC CE未生效，能够理解一致。当gNB在UL时隙n接收到来自UE的HARQ反馈信息之后，gNB可以基于HARQ反馈信息指示UE是否成功接收到MAC CE，确定UE侧MAC CE是否已生效，UE采用Koffset,0还是Koffset,1。从而得到在T1时间段与T3时间段之间的T2时间段，UE与gNB对MAC CE是否生效的理解不能达成一致。该方案提出在该T2时间段gNB仅采用回退(fallback)格式(format)的DCI调度上行信息，并且fallback DCI format相关的传输均采用小区专用(cell-specific)Koffset。UE接收到fallback DCI format的DCI后，采用cell-specific Koffset，确定该DCI调度的上行信息的传输时隙。使得UE与gNB在T2时间段内对Koffset的理解一致。
图7所示的方案仍然存在理解不一致的问题，如尽管gNB已经收到了HARQ-ACK，但gNB侧MAC CE仍未生效，在时隙N的3ms之后才生效，而UE侧MAC CE已经生效，双方仍存在对于Koffset的理解不一致的问题。另一方面，该方案中gNB在T1、T2和T3需要分别采用Koffset,0、cell-specific Koffset和Koffset,1，使得gNB在连续的三个阶段采用三个不同的Koffset值，增加了gNB和UE的调度复杂度。并且，cell-specific Koffset是适用于随机接入阶段，是为满足小区边缘UE设计的。对于非小区边缘UE，cell-specific Koffset一般大于UE专用(UE-specific)的Koffset，在数据传输阶段采用cell-specific Koffset将带来不必要的传输时延。以及，如前文介绍MAC CE可以用于多种上行配置的激活，该方案仅能够解决Koffset的生效时间理解不一致的问题，对于激活其他上行配置(如DRX配置、PUCCH空间关系等)的MAC CE仍存在一段时间的对生效时间理解不一致的问题。
针对上述终端设备与网络设备对被激活的上行配置的生效时间理解不一致的问题，本申请提出了被激活的上行配置在终端设备侧的生效时刻的定义，使得终端设备与网络设备能够对上行配置的生效时刻理解一致，减小了调度失败的概率，提高了通信的可靠性。
下面将结合附图，对本申请提供的技术方案进行描述。图8是本申请实施例提供的通信方法800的示意性流程图。图8以网络设备和终端设备进行示意，网络设备和/或终端设备也可以替换为用于执行该方法的芯片，模块等，本申请不限于此。
S801，网络设备向终端设备发送第一信息，该第一信息用于激活第一上行配置。
相应地，终端设备接收来自网络设备的该第一信息，根据该第一信息确定该第一上行配置被激活。
例如，图9所示，gNB(即网络设备的一个示例)在DL时隙Y的PDSCH向终端设备发送MAC CE(即第一信息的一个示例)，该MAC CE用于激活第一上行配置。相应地，UE(即终端设备的一个示例)在DL时隙Y的PDSCH接收来自gNB的MAC CE，根据该MAC CE确定第一上行配置被激活。需要说明的是，为了更好的理解本申请提供的通信方法，本申请实施例中主要以网络设备为gNB，终端设备为UE，第一信息为MAC  CE为例对本方案进行描述，应理解，本申请并不限于此，网络设备、终端设备可以分别是但不限于前文中举例的网络设备、终端设备。
可选地，该第一上行配置可以包括但不限于以下一项或多项：
用于确定下行信息与上行信息时序关系的时间间隔Koffset、DRX配置或上行波束配置。
S802，终端设备在第一时间单元向网络设备发送第二信息，该第二信息用于确认接收到该第一信息。
终端设备成功接收到该第一信息后，向网络设备发送用于确认接收到第一信息的第二信息，如第二信息可以是第一信息的HARQ-ACK，以便网络设备确定终端设备已接收到第一信息，获知第一上行配置被激活。
终端设备与网络设备的传输资源在时间上被划分为了连续且等时长的多个时间单元，并通过时间单元的标识对时间单元进行区分。作为示例非限定，本申请中的时间单元可以是时域符号(如时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM))、微时隙(mini-slot)、时隙(slot)、子帧(subframe)或帧(frame)。本申请个示例中均以时间单元为时隙为例进行说明，应理解，本申请并不限于此。
例如图9所示，UE在DL时隙Y的PDSCH上接收到MAC CE后，根据gNB指示的KPDSCH-HARQ，确定在与时隙Y之间间隔KPDSCH-HARQ的UL时隙N发送HARQ-ACK。则UE确定UL时隙N(即UL时隙N为第一时间单元的一个示例)向gNB发送HARQ-ACK。相应地，gNB在gNB的UL时隙N接收来自UE的HARQ-ACK，确定UE已接收到MAC CE。
S803，终端设备确定第一上行配置的生效时刻，该生效时刻与第一时间单元之间的时间间隔为第一时间间隔，其中，第一时间间隔大于第一时间偏移量与第二时间偏移量之和。
终端设备在该生效时刻开始应用第一上行配置，在该生效时刻之前仍应用第一上行配置生效之前已生效的第二上行配置。其中，第一时间偏移量是同一时间单元标识对应的网络设备的上行时间单元与下行时间单元之间的时间偏移量，例如，第一时间偏移量为图9所示的KgNB,DL-UL，该第二时间偏移量是同一时间单元标识对应的终端设备的上行时间单元与下行时间单元之间的偏移量，例如，第二时间偏移量为图9所示的KUE,DL-UL。也就是第一时间间隔大于KgNB,DL-UL+KUE,DL-UL。
终端设备可以根据发送第二信息的第一时间单元和第一时间间隔，确定第一时间单元之后与该第一时间单元间隔第一时间间隔的绝对时间，终端设备认为该绝对时间为第一上行配置的生效时刻。该生效时刻既适用于DL时隙又适用于UL时隙。例如图9所示，终端设备确定与UL时隙N(即第一时间单元的一个示例)间隔第一时间间隔的绝对时间T为第一上行配置的生效时刻。该绝对时间T既适用于UE的DL时隙又适用于UE的UL时隙。如UE在该生效时刻T之前的DL时隙接收到一个上行调度信息，则UE采用第二上行配置发送响应于该上行调度信息的上行信息，若在生效时刻T之后的DL时隙接收到一个上行调度信息，则UE采用已生效的第一上行配置发送响应于该上行调度信息的上行信息。若UE在该生效时刻T之前的UL时隙向网络设备发送上行信息，如发送信道状态信息(channel state information，CSI)，则该UE采用该第二上行配置发送该CSI。若UE在该生效时刻之后的UL时隙采用已生效的第一上行配置向网络设备发送CSI。
终端设备可以根据但不限于以下两种实施方式确定第一时间间隔。
一种实施方式中，网络设备可以向终端设备发送指示信息，该指示信息用于指示该第 一时间间隔，该第一时间间隔大于第一时间偏移量与第二时间偏移量之和。终端设备根据该指示信息确定第一时间间隔。
例如，该指示第一时间间隔的指示信息可以是无线资源控制(radio resource control，RRC)消息中的一个信元(information element，IE)，如可以通过系统消息块(system information block，SIB)中的一个IE指示该第一时间间隔。示例性地，该IE可以称为MAC CE生效间隔IE，应理解，本申请对IE的具体名称不作限定。第一时间间隔的指示信息也可以承载在终端设备专用的(UE-specific)RRC消息中。或者，该第一时间间隔的指示信息可以是MAC CE中的一个指示域，如该指示信息可以是激活第一上行配置的MAC CE(即第一信息)中的一个指示域，但不申请不限于此，该指示信息也可以是其他MAC CE中的一个指示域。再或者，该指示信息可以是DCI中的一个指示域。如在现有DCI中增加一个指示域指示该第一时间间隔，或者复用现有DCI中的一个指示域，本申请对此不作限定。
终端设备根据终端设备发送第二信息的第一时间单元和该指示信息指示的第一时间间隔，确定与第一时间单元间隔第一时间间隔的时刻为第一上行配置的生效时刻。例如图9所示，时间单元为时隙，UE确定在UL时隙N发送HARQ-ACK，则与UL时隙N间隔第一时间间隔的时刻为该第一上行配置的生效时刻。
可选地，该第一时间间隔为时间单元的个数，例如，时隙的个数。
如图9所示，UE根据UL时隙N和第一时间间隔，确定与UL时隙N间隔第一时间间隔的UL时隙E″的起始时刻为该第一上行配置的生效时刻。示例性的，可以参考下式进行计算：
E″UE,UL＝NUE,UL+Kint1，
其中，NUE,UL表示UE的UL时隙N的时隙标识，E″UE,UL表示UE的UL时隙E″的时隙标识，Kint1表示第一时间间隔包含的时隙个数。
相应地，网络设备在UL时隙N接收到来自终端设备的HARQ-ACK反馈后，可以确定与UL时隙N之间间隔第二时间间隔的时刻为该上行配置的生效时刻。该第二时间间隔是第一时间间隔减去第一时间偏移量和第二时间偏移量得到的。
可选地，该第二时间间隔为时间单元的个数。
如图9所示，gNB根据UL时隙N和第二时间间隔，确定与UL时隙N间隔第二时间间隔的UL时隙E的起始时刻为该第一上行配置的生效时刻。示例性的，可以参考下式进行计算：
EgNB,UL＝NgNB,UL+Kint2
其中，NgNB,UL表示gNB的UL时隙N的时隙标识，EgNB,UL表示gNB的UL时隙E的时隙标识，Kint2表示第二时间间隔包含的时隙个数。
另一种实施方式中，该第一时间间隔大于或等于第二时间间隔、第一时间偏移量和第二时间偏移量之和。
其中，该第二时间间隔可以是预定义的配置生效最小时间间隔。可以规定配置生效的最小时间间隔(即第二时间间隔)使得网络设备与终端设备对配置生效的最小时间间隔达成共识。但本申请不限于此，第二时间间隔也可以是网络设备为终端设备配置的。
示例一，网络设备可以为终端设备预配置第一时间偏移量和第二时间偏移量。终端设备可以根据预定义的第二时间间隔，以及网络设备配置的第一时间偏移量和第二时间偏移 量，确定第一时间间隔。该第一时间间隔为第二时间间隔、第一时间偏移量和第二时间偏移量之和。
第二时间偏移量可以是网络设备通过随机接入消息配置给终端设备的，或者该第二时间偏移量可以是终端设备根据终端设备的位置和服务卫星的星历信息计算得到的。如第二时间偏移量可以称为UE的上行时间提前TA。第一时间偏移量可以是网络设备通过配置信息(如MAC CE或RRC消息)配置给终端设备的。但本申请不限于此，第一时间偏移量和第二时间偏移量也可以是通过同一配置信息中的不同信元或不同指示域配置给终端设备的。
示例二，网络设备可以为终端设备预配置用于确定配置生效时刻的时间间隔A，该时间间隔A大于或等于第一时间偏移量和第二时间偏移量之和。终端设备根据预定义的第二时间间隔和网络设备配置的时间间隔A，确定第一时间间隔。该第一时间间隔为时间间隔A与第二时间间隔之和。
在该实施方式中，终端设备确定第一时间间隔(如根据但不限于上述示例一或上述示例二确定第一时间间隔)后，终端设备可以根据第一时间间隔确定第一上行配置的生效时刻。例如图9所示，终端设备可以确定第一上行配置的生效时刻为与终端设备发送HARQ-ACK的UL时隙N之间间隔第一时间间隔的时刻。相应地，gNB在gNB的UL时隙N接收到HARQ-ACK后，根据第二时间间隔，确定第一上行配置的在gNB侧的生效时刻为与该UL时隙N之间间隔第二时间间隔的时刻。
以上介绍了终端设备基于第一时间单元确定第一上行配置的生效时刻(即绝对时间)以及网络设备基于接收到第二信息的时间单元确定第一上行配置的生效时刻的方式，但申请不限于此，终端设备、网络设备还可以采用如下可选方式，基于上行时间单元的标识和下行时间单元的标识，确定第一上行配置的生效时刻。
可选地，该终端设备确定该第一上行配置的生效时刻，包括：终端设备根据第一时间单元和第二时间间隔，确定第二时间单元，该第二时间单元与第一时间单元之间的时间间隔为第二时间间隔。终端设备再根据该第二时间单元的上行时间单元的第一标识，确定该第一标识对应的下行时间单元(记作第三时间单元)。以及终端设备根据该第一标识对应的下行时间单元和该第一时间偏移量，确定该生效时刻是与第三时间单元之间的时间间隔为该第一时间偏移量的时间单元(记作第四时间单元)的起始时刻。
例如图9所示，时间单元为时隙，第二时间间隔为4个时隙，UE可以根据发送HARQ-ACK的UL时隙N和第二时间间隔，确定与UL时隙N间隔4个时隙的UL时隙E(该DL时隙E′为第二时间单元的一个示例)。UE再根据UL时隙E的时隙标识为E，确定DL时隙E(该DL时隙E′为第三时间单元的一个示例)，即时隙标识E标识的下行时隙。UE确定DL时隙E之后，再基于DL时隙E和第一时间偏移量，确定第一上行配置的生效时刻是与DL时隙E之间间隔第一时间偏移量的DL时隙E′(该DL时隙E′为第四时间单元的一个示例)的起始时刻。
或者，UE可以根据发送HARQ-ACK的UL时隙N的时隙标识N，确定DL时隙N，再确定与DL时隙N间隔的第二时间间隔的DL时隙E。UE再根据DL时隙E和第一时间偏移量，确定与DL时隙E之间间隔一个时隙的DL时隙E′。从而UE确定该DL时隙E′的起始时刻为第一上行配置的生效时刻。
相应地，网络设备根据接收到来自终端设备的第二信息的时间单元(记作第七时间单 元)和第二时间间隔，确定第一上行配置的生效时刻是与接收到第二信息的时间单元间隔第二时间间隔的时间单元(记作第八时间单元)的生效时刻。
以及，网络设备可以根据与接收到第二信息的时间单元间隔第二时间间隔的时间单元对应的上行时间单元的第二标识，确定该第二标识对应的下行时间单元(记作第六时间单元)。网络设备再根据第二标识对应的下行时间单元和第一时间偏移量，确定该第一上行配置的生效时刻对应的下行时间单元是与第二标识对应的下行时间单元之间间隔第一时间偏移量的时间单元。
例如图9所示，时间单元为时隙，第二时间间隔为4个时隙，gNB可以根据接收到HARQ-ACK的UL时隙N(该UL时隙N为第七时间单元的一个示例)和第二时间间隔，确定与UL时隙N之间间隔4个时隙的UL时隙E(该UL时隙E为第八时间单元的一个示例)，该UL时隙E的起始时刻为该第一上行配置的生效时刻。以及，gNB可以根据UL时隙E的上行时隙标识E，确定DL时隙E(该UL时隙E为第六时间单元的一个示例)，即该时隙标识E标识的下行时隙。网络设备再确定该DL时隙E和第一时间偏移量为一个时隙，确定与DL时隙E间隔一个时隙的DL时隙E′(该DL时隙E′为第六时间单元的一个示例)，确定该DL时隙E′为该第一上行配置的生效时刻对应的DL时隙。
或者，gNB可以根据根据接收到HARQ-ACK的UL时隙N的时隙标识N，确定DL时隙N，即该时隙标识N标识的下行时隙。网络设备再确定该DL时隙N的第二时间间隔之后的DL时隙E，以及根据第一时间偏移量为一个时隙，确定该DL时隙E之后的DL时隙E′，从而确定该DL时隙E′为第一上行配置的生效时刻对应的DL时隙。
应理解，以上以终端设备、网络设备将承载第二信息的时间单元作为参考时间单元确定第一上行配置的生效时刻为例进行了说明，本申请不限于此，任何等效的替换参考时间单元的方式均应落在本申请的保护范围之内。
可选地，参考时间单元还可以是承载第一信息的时间单元(记作第五时间单元)。该承载第一信息的时间单元与第一时间单元之间的时间间隔为第四时间间隔，该第四时间间隔为网络设备指示的。则第一上行配置的生效时刻与承载第一信息的时间单元之间的时间间隔为第四时间间隔与第一时间间隔之和。
例如图9所示，gNB在DL时隙Y(该DL时隙Y为第五时间单元的一个示例)的PDSCH向UE发送用于激活第一上行配置的MAC CE，UE在UE的DL时隙Y的PDSCH接收到该MAC CE。UE可以基于UL时隙Y、KPDSCH-HARQ(即第四时间间隔)以及第一时间间隔，确定第一上行配置的生效时刻。该第一上行配置的生效时刻(即UL时隙E″)与UL时隙Y之间的时间间隔为KPDSCH-HARQ与第一时间间隔之和，示例性的，可以参考如下式进行计算：
E″UE,UL＝YUE,UL+KPDSCH-HARQ+Kint1。
相应地，网络设备可以基于PDSCH与反馈信息的时序关系，根据UL时隙Y、KPDSCH- HARQ、第二时间间隔，确定UL时隙E的起始时刻为该上行配置的生效时刻。示例性的，可以参考下式进行计算：
EgNB,UL＝YgNB,UL+KPDSCH-HARQ+Kint2。
需要说明的是，本申请实施例中以两个时间单元之间的时间间隔为两个时间单元的起始时刻之间的时间间隔为例进行说明，或者当两个时间单元之间的时间间隔以时间单元的标识表示时，可以理解为两个时间单元之间的时间间隔为该两个时间单元的时间单元标识的差值。如图9示例中gNB UL时隙N与UL时隙E之间的第二时间间隔为4个时隙，如 图9所示是UL时隙N的起始时刻与UL时隙E的起始时刻之间的时间间隔，即E＝N+4。但本申请不限于此，本申请对时间间隔的表示方式不作限定，应理解，不同时间间隔的表示方式的等价替换均应落在本申请的保护范围内。如两个时间单元之间的时间间隔可以以前一个时间单元的结束时刻与后一个时间单元的起始时刻之间间隔的时间长度或时间单元的个数表示。那么，图9示例中gNB UL时隙N与UL时隙E之间的第二时间间隔可以替换为3个时隙，即Kint2＝3，或者SCS为15kHz时，该第二时间间隔可以是时间长度3ms。若第二时间间隔采用该方式表示时间间隔，则时隙标识E的通过E＝N+Kint2+1计算得到。以及上述EgNB,UL可以参考下式进行计算：
EgNB,UL＝NgNB,UL+Kint2+1＝YgNB,UL+KPDSCH-HARQ+Kint2+1
若第一时间间隔也采用该方式表示时间间隔，则前文中的E″UE,UL可以参考下式进行计算：
E″UE,UL＝NUE,UL+Kint1+1＝YUE,UL+KPDSCH-HARQ+Kint1+1
在上述两式的第二个等号后，Kint1、Kint2以前一个时间单元的结束时刻与后一个时间单元的起始时刻之间间隔的时隙个数表示，而KPDSCH-HARQ以PDSCH和HARQ各自所在的时间单元的起始时刻之间间隔的时隙个数表示。另一种方式中，KPDSCH-HARQ同样可以以PDSCH所在的时间单元的结束时刻与HARQ所在的时间单元的起始时刻之间间隔的时间单元的个数表示。则上述EgNB,UL可以参考下式进行计算：
EgNB,UL＝NgNB,UL+Kint2+1＝YgNB,UL+KPDSCH-HARQ+Kint2+2
上述E″UE,UL可以参考下式进行计算：
E″UE,UL＝NUE,UL+Kint1+1＝YUE,UL+KPDSCH-HARQ+Kint1+2
以及本申请中的其他时间间隔也可以参考上述表示方式，为了简要，在此不再一一例举。
以上介绍了终端设备、网络设备确定第一上行配置的生效时刻的方式，若终端设备在第一上行配置生效时刻之前，接收来自网络设备的第三信息，第三信息用于调度终端设备发送上行信息。终端设备根据第二上行配置，发送该上行信息，该第二上行配置为第一上行配置生效之前已生效的上行配置。若终端设备在第一上行生效时刻之后接收到来自网络设备的调度信息，终端设备根据第一上行配置响应该调度信息发送该上行信息。能够使得终端设备与网络设备对一次调度采用的上行配置的理解达成一致，能够减小因通信双方理解不一致而导致调度失败的情况发生的概率，提高通信的可靠性。
例如图10所示，gNB在gNB的DL时隙Y的PDSCH向UE发送MAC CE，该MAC CE激活第一上行配置。UE在UE的DL时隙Y接收到该MAC CE，确定第一上行配置被激活，并确定在UE的UL时隙N向gNB发送HARQ-ACK，以及UE根据第一时间间隔和UL时隙N，确定该第一上行配置的生效时刻T与UL时隙N间隔第一时间间隔，即UL时隙E″的起始时刻，UE在第一上行配置之前采用第二上行配置发送上行信息。
一个示例中，该MAC CE用于更新Koffset,1，该Koffset,1用于更新UE发送调度响应信息的时间间隔Koffset。如前文描述，UE可以确定该Koffset,1的生效时刻为UL时隙E″的起始时刻，则UE在第一上行配置的生效时刻之前采用第二上行配置，即该Koffset,1的生效之前已生效的Koffset,0。如UE确定发送HARQ-ACK的时隙N是根据已生效的Koffset,0，以及调度该MAC CE的DCI指示的K1，确定时隙N与时隙Y之间的时间间隔为Koffset,0+K1。若gNB在DL时隙P向UE发送DCI，该DCI用于调度UE发送上行信息(如上行数据)。 UE在UE的DL时隙P接收到该DCI后，确定DL时隙P的绝对时间在该Koffset,1的生效时刻之前，即该Koffset,1未生效，则UE基于Koffset,0和DL时隙P接收到的该DCI指示的偏移量K2，确定UL时隙P与响应于该DCI发送的上行信息之间的时间间隔为Koffset,0+K2，则UE确定在UE的UL时隙Q中的PUSCH发送上行信息，示例性的，可以参考下式进行计算：
QUE,UL＝PUE,UL+Koffset,0+K2。
相应地，gNB在DL时隙P发送DCI，由于此时还未接收到UE对更新Koffset,1的MACCE的HARQ-ACK，gNB认为Koffset,1未生效，基于Koffset,0和偏移量K2，确定UE发送上行信息的UL时隙Q与UL时隙P之间的时间间隔为Koffset,0+K2，则gNB在gNB的UL时隙Q接收来自UE的上行信息，示例性的，可以参考下式进行计算：
QgNB,UL＝PgNB,UL+Koffset,0+K2。
如上，采用本申请提供的上行配置的生效时刻确定方式，gNB与UE能够对采用的用于确定UE发送调度响应信息的时间间隔Koffset达成共识，减小采用不同的Koffset确定发送调度响应信息的时刻的概率，提高了通信的可靠性。
另一个示例中，该MAC CE用于激活DRX配置，即网络设备通过该MAC CE指示终端设备进入休眠状态。如图10所示，UE在DL时隙Y接收到MAC CE后，确定DRX配置将被激活。以及UE可以根据承载HARQ反馈的UL时隙N和第一时间间隔，确定DRX配置的生效时刻与UL时隙N之间的间隔为第一时间间隔，即确定DRX配置生效时刻为UE的UL时隙E″的起始时刻。由于gNB在UL时隙P还为接收到UE对激活DRX配置的MAC CE的HARQ-ACK，gNB认为UE的DRX配置未生效，gNB可以在DL时隙P向UE发送调度上行信息的DCI，UE在UE的DL时隙P接收到该DCI，该DL时隙P的绝对时间在DRX配置的生效时刻之前，UE未进入休眠状态，仍在监听PDCCH，收到该DCI后需要响应该DCI，UE基于当前生效的Koffset,0和该DCI指示的偏移量K2，确定UL时隙Q，UE在该UL时隙Q中的PUSCH向gNB发送上行信息。相应地，gNB基于当前生效的Koffset,0和偏移量K2，确定UE发送上行信息的UL时隙Q，在gNB的UL时隙Q接收来自UE的上行信息。而gNB确定DRX配置的生效时刻为UL时隙E的起始时刻，由于DRX配置生效后UE进入休眠状态，gNB在DRX配置的生效时刻之后不向UE发送调度信息。UE在DRX配置的生效时刻(即UE的UL时隙E″的起始时刻，或UE的DL时隙E′的起始时刻)进入休眠状态不接收调度信息。如上，采用本申请提供的上行配置的生效时刻确定方式，gNB与UE确定的DRX配置的生效时刻，使得gNB与UE能够对UE能够响应调度的时间达成共识，减小了因UE无法响应gNB的调度而造成资源浪费的情况的概率，提高了通信的可靠性。
又一个示例中，如图11所示，gNB在gNB的DL时隙Y的PDSCH 1向UE发送MAC CE，该MAC CE为PUCCH空间关系激活MAC CE，用于激活PUCCH对应的波束配置1(如波束配置1配置了发送波束方向)。UE在UE的DL时隙Y接收到该MAC CE，确定PUCCH对应的波束配置1将被激活，并确定在UE的UL时隙N中的PUCCH向gNB发送该MAC CE的HARQ-ACK 1，以及UE根据第一时间间隔和UL时隙N，确定PUCCH对应的波束配置1的生效时刻T与UL时隙N间隔第一时间间隔，即波束配置1的生效时刻为UE的UL时隙E″的起始时刻。UE在PUCCH对应的波束配置1的生效时 刻之前采用波束0发送上行控制信息(如HARQ反馈信息等)。如UE的UL时隙N该波束1还未生效，UE采用目前已生效的波束配置0在PUCCH向gNB发送该MAC CE的反馈信息，即HARQ-ACK 1。以及gNB可以在DL时隙P向UE发送PDSCH 2。UE在UE的DL时隙P接收到该PDSCH 2，由于DL时隙P的绝对时间在波束配置1的生效时刻之前，UE采用波束配置0发送该PDSCH 2的反馈信息HARQ-ACK 2，如图11所示，UE在UL时隙Q采用波束配置0发送HARQ-ACK 2。相应地，gNB在DL时隙P发送PDSCH 2，由于此时还未接收到UE对PUCCH空间关系激活MAC CE的HARQ-ACK 1，gNB认为PUCCH对应的波束配置1未生效，UE采用波束配置0发送HARQ-ACK 2，gNB相应地采用波束配置0接收来自UE的HARQ-ACK 2。gNB在PUCCH对应的波束配置1的生效时刻之后的DL时隙发送的PDSCH，UE将在PUCCH对应的波束配置1的生效时刻之后接收到该PDSCH，UE采用波束配置1发送该PDSCH的HARQ反馈信息，相应地，gNB采用波束配置1接收来自UE的HARQ反馈信息。使得gNB与UE能够对PUCCH对应的波束配置对达成共识，减小采用不对应的波束配置发送、接收上行信息的概率，提高了通信的可靠性。
可选地，终端设备、网络设备可以确定在各自第一上行配置的生效时刻之前的第三时间间隔。该第三时间间隔大于或等于第一时间偏移量与第二时间偏移量之和。该第一上行配置的生效时刻之前的第三时间间隔可以称为上行配置生效的过渡期或上行配置的模糊期，但本申请不限于此。
例如图13所示，该第三时间间隔等于第一时间偏移量与第二时间偏移量之和，示例性地，gNB侧和UE侧的过渡期具体指时隙标识为N-KgNB,DL-UL至N+KUE,DL-UL的DL时隙，记作DL时隙[N-KgNB,DL-UL，N+KUE,DL-UL]，其中，N＝Y+KPDSCH-HARQ，则gNB侧和UE侧的过渡期还可以表示为DL时隙[Y+KPDSCH-HARQ-KgNB,DL-UL，Y+KPDSCH-HARQ+KUE,DL-UL]。以上以两个时间单元之间的时间间隔为两个时间单元的起始时刻之间的时间间隔为例进行说明，或者当两个时间单元之间的时间间隔以时间单元的标识表示时，可以理解为两个时间单元之间的时间间隔为该两个时间单元的时间单元标识的差值。但本申请不限于此，本申请对时间间隔的表示方式不作限定，应理解，不同时间间隔的表示方式的等价替换均应落在本申请的保护范围内。
针对上述终端设备与网络设备对被激活的上行配置的生效时间理解不一致的问题，本申请提出了被激活的上行配置在终端设备侧的生效时刻的定义，在图8所示实施例提出了终端设备与网络设备各自确定的第一上行配置的生效时刻之前采用第一上行配置生效之前已生效的第二上行配置进行上行传输，在第一上行配置的生效时刻之后采用第一上行配置进行上行传输。终端设备与网络设备对采用的上行配置理解一致，减小了调度失败的概率，提高了通信的可靠性。本申请还提供了如图12所示的另一个实施例，由于终端设备与网络设备在第一上行配置的生效时刻之前的一段时间内对采用的上行配置可能未达成共识，如终端设备采用已生效的第一上行配置，网络设备认为第一上行配置未生效，采用第二上行配置接收上行传输，造成上行信息无法正确接收。因此，图12所示实施例提出可以规定网络设备在可能与终端设备对采用的上行配置理解不一致的时间段内不发送上行信息的调度信息，以减小了调度失败的概率，提高了通信的可靠性。
图12是本申请实施例提供的通信方法1200的示意性流程图。图12以网络设备和终端设备进行示意，网络设备和/或终端设备也可以替换为用于执行该方法的芯片，模块等， 本申请不限于此。需要说明的是，图12所示实施例中与图8所示实施例相同的部分可以参考前文中对图8所示实施例的描述，为了简要，在此不再赘述。
S1201，网络设备向终端设备发送第一信息，该第一信息用于激活第一上行配置。
相应地，终端设备接收来自网络设备的该第一信息。终端设备根据该第一信息确定第一上行配置被激活。
S1202，网络设备确定在第一上行配置的生效时刻之前的第三时间间隔内，不向终端设备发送上行信息的调度信息。
其中，该第三时间间隔大于或等于第一时间偏移量与第二时间偏移量之和。该第一上行配置的生效时刻之前的第三时间间隔可以称为上行配置生效的过渡期或上行配置的模糊期，但本申请不限于此。
网络设备可以基于第一信息与反馈信息的时序关系，确定承载终端设备发送的第一信息的反馈信息的UL时隙，再根据第二时间间隔可以确定若终端设备接收到第一信息，第一上行配置的生效时刻。如图13所示，网络设备在DL时隙Y发送用于激活第一上行配置的MAC CE，则网络设备可以基于UL时隙Y、KPDSCH-HARQ(即第四时间间隔)以及第一时间间隔，确定在终端设备接收到该第一信息的情况下该第一上行配置的生效时刻，即UL时隙E的起始时刻。由于在该第一上行配置的生效时刻之前可能存在网络设备与终端设备对采用的上行配置理解不一致的情况，如终端设备成功接收到第一信息的情况下，终端设备将采用第一上行配置进行上行传输，而网络设备采用第二上行配置进行上行接收，造成上行信息无法正确接收的情况。因此，本申请提出网络设备在第一上行配置的生效时刻之前的第三时间间隔内，网络设备不向终端设备发送上行信息的调度信息。
例如图13所示以该第三时间间隔是第一时间偏移量和第二时间偏移量之和为例进行说明，第一时间偏移量KgNB,DL-UL为1个时隙，第二时间偏移量KUE,DL-UL为5个时隙。gNB可以确定第三时间间隔为KgNB,DL-UL+KgNB,DL-UL，即6个时隙。gNB在gNB的DL时隙Y发送用于激活第一上行配置的MAC CE，并基于该MAC CE的HARQ-ACK承载在UL时隙N和第一时间间隔，确定与该UL时隙N的间隔为第一时间间隔的第一上行配置的生效时刻，即gNB的UL时隙E的起始时刻或DL时隙E′的起始时刻。gNB基于第三时间间隔为6个时隙，确定该第一上行配置的生效时刻之前的6个时隙内为上行配置生效的过渡期，gNB在过渡期不向UE发送上行调度信息，由于UE不会收到上行调度信息，因此也不会发送上行信息。若gNB在过渡期之前向UE发送上行调度DCI，则gNB采用第二上行配置接收UE响应于该DCI发送的上行信息。以及gNB在过渡期之后向UE发送上行调度DCI，则gNB采用已生效的第一上行配置接收UE响应于该DCI向gNB发送上行信息。能够减小gNB和UE因理解不一致导致调度失败的情况发生的概率。
可选地，终端设备在第一上行配置的生效时刻之前的第三时间间隔内接收到第四信息，该第四信息用于调度终端设备发送上行信息，终端设备根据在第三时间间隔内接收到所述第四信息，确定不响应该第四信息。
终端设备接收到第一信息后，可以确定第一上行配置的生效时刻(具体确定方式可以参考图8所示示例中的描述，为了简要在此不再赘述)。由于网络设备在网络设备确定的第一上行配置的生效时刻之前的第三时间间隔内不向终端设备发送上行信息的调度信息。相应地，终端设备不期望在第一上行配置的生效时刻之前的第三时间间隔内接收到上行信息的调度信息。若终端设备在第一上行配置的生效时刻之前的第三时间间隔内接收到上行 信息的调度信息，则终端设备认为该调度信息不正确，终端设备不响应该调度信息。
一个示例中，该第三时间间隔是第一时间偏移量和第二时间偏移量之和。网络设备可以为终端设备配置第一时间偏移量和第二时间偏移量，终端设备基于第一时间偏移量和第二时间偏移量确定第三时间间隔。使得终端设备与网络设备对第三时间间隔达成共识。
另一个示例中，网络设备可以为终端设备配置该第三时间间隔，以便终端设备与网络设备对第三时间间隔达成共识。该第三时间间隔大于或等于第一时间偏移量和第二时间偏移量之和。
例如图13所示，该第三时间间隔是第一时间偏移量和第二时间偏移量之和，第一时间偏移量KgNB,DL-UL为1个时隙，第二时间偏移量KUE,DL-UL为5个时隙。UE可以确定第三时间间隔为KgNB,DL-UL+KgNB,DL-UL，即6个时隙。UE在UE的DL时隙Y接收到来自gNB的激活第一上行配置的MAC CE，并基于该MAC CE的HARQ-ACK承载在UE的UL时隙N和第一时间间隔，确定与该UL时隙N间隔第一时间间隔的第一上行配置的生效时刻，即UE的UL时隙E″或DL时隙E′的起始时刻。UE基于第三时间间隔为6个时隙，确定该第一上行配置的生效时刻之前的6个时隙内为上行配置生效的过渡期。若UE在UE的DL时隙X接收到DCI，该DCI为上行信息的调度信息，由于时隙X属于第一上行配置的生效时刻之前的第三时间间隔，UE认为该DCI不正确，不响应该DCI，即UE不发送该DCI调度的上行信息。若UE在过渡期之前接收到上行调度DCI，则UE响应于该DCI采用第二上行配置向gNB发送上行信息。以及UE在过渡期之后接收到上行调度DCI，则UE响应于该DCI采用已生效的第一上行配置向gNB发送上行信息。
根据本申请的上述方案，终端设备能够确定被激活的上行配置的生效时刻，能够减小终端设备与网络设备采用的上行配置不一致造成的调度失败的概率，提高通信的可靠性。
