第一种示例中，当N等于1时，上述当所述第一时频资源与承载所述终端设备待发送的N个上行信道的第二时频资源重叠时，终端设备调整所述N个上行信道的发送可以包括：当所述第二时频资源的部分时频资源与所述第一时频资源重叠，且所述第二时频资源的剩余部分的时频资源与所述第一时频资源不重叠时，终端设备调整所述上行信道的发送。
第二种示例中，当N大于或等于2时，则上述第二时频资源可以包括N个时间单元，每个时间单元承载一个所述上行信道，每个所述上行信道承载相同的信息，所述N个时间单元中M个时间单元与所述第一时频资源重叠，所述N个时间单元中除所述M个时间单元以外的Q个时间单元与所述第一时频资源不重叠，其中，M，Q均为小于或等于N的正整数，且N为M与Q之和。
针对上述第一种示例和第二种示例，上述终端设备调整所述N个上行信道的发送可以是，终端设备丢弃所述第二时频资源上承载的所述N个上行信道。即终端设备不发送承载在第二时频资源上承载的N个上行信道，这样可以完全避免第二时频资源上承载的信息对第一时频资源上承载的信息的干扰。
可选的，针对第二种示例，终端设备调整所述N个上行信道的发送可以是丢弃部分上行信道，发送部分上行信道，此时根据上行信道的调度方式的不同，分为两种情况。
第一种情况，当所述上行信道是基于调度的上行信道，则终端设备调整所述上行信道的发送，可以包括：丢弃所述M个时间单元上承载的所述上行信道；且发送所述Q个时间单元上承载的所述上行信道。
在第一种情况下，所述N个上行信道中的P个上行信道可以共享一个DMRS，其中，P为小于或等于Q的正整数。此时，本申请实施例的方法还可以包括：当承载所述P个上行信道中R个上行信道的时间单元属于所述Q个时间单元，且承载所述DMRS的时间单元属于所述M个时间单元，终端设备确定所述R个上行信道共享所述Q个时间单元中承载的第一个DMRS，其中，R为小于所述P的正整数。
第二种情况，当所述上行信道是免调度或免许可的上行信道，上述终端设备调整所述上行信道的发送，可以包括：从所述Q个时间单元中确定第一个承载DMRS的目标时间单元；丢弃所述N个时间单元中所述目标时间单元之前的时间单元上承载的所述上行信道；并发送所述目标时间单元、以及所述N个时间单元中所述目标时间单元之后的时间单元上承载的所述上行信道。
即本申请实施例的技术方案，当上行信道是基于调度的上行信道时，终端设备丢弃所述M个时间单元上承载的所述上行信道并发送所述Q个时间单元上承载的所述上行信道。当上行信道是免调度或免许可的上行信道，则终端设备首先从所述Q个时间单元中确定第一个承载DMRS的目标时间单元；丢弃N个时间单元中目标时间单元之前的时间单元上承载的上行信道；并发送目标时间单元、以及N个时间单元中目标时间单元之后的时间单元上承载的上行信道。这样，在实现对承载在第一时频资源上的上行信息的准确发送的同时，传输第二时频资源上承载的至少一个上行信道，进一步提高了通信系统的上行传输的可靠性和传输效率。
可选的，上述终端设备调整所述N个上行信道的发送还可以是，终端设备暂时不 发送承载在第二时频资源上的所有上行信道。待承载在第一时频资源上的上行信息发送结束后，再发送承载在第二时频资源上的N个上行信道。或者，当所述上行信道是基于调度的上行信道，则终端设备暂时不发送所述M个时间单元上承载的所述上行信道，且发送所述Q个时间单元上承载的所述上行信道，待承载在第一时频资源上的上行信息发送结束后，再发送所述M个时间单元上承载的所述上行信道。或者，当所述上行信道是基于免调度或免许可的上行信道，则终端设备暂时不发送所述N个时间单元中所述目标时间单元之前的时间单元上承载的所述上行信道，并发送所述目标时间单元、以及所述N个时间单元中所述目标时间单元之后的时间单元上承载的所述上行信道，待承载在第一时频资源上的上行信息发送结束后，再发送所述N个时间单元中所述目标时间单元之前的时间单元上承载的所述上行信道。这样可以保证对承载在第一时频资源上的上行信息的准确发送的同时，实现第二时频资源上承载的上行信道的可靠传输。
第三种情况，若上述N个上行信道是格式0的上行控制信道(physical uplink control channel，PUCCH)，且当第二时频资源的部分时频资源与第一时频资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠时，终端设备调整N个上行信道的发送可以包括：在第二时频资源与第一时频资源时域不重叠的时频资源上发送上述N个上行信道承载的信息，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信息发送，该静默可以理解为放弃。该第三种情况下，同一个格式0的PUCCH的不同符号上承载的信息相同，因此，在第二时频资源与第一时频资源时域不重叠的时频资源上发送该N个上行信道承载的信息，可以避免格式0的PUCCH的重复发送，进而节约了通信资源。
在一种示例中，若上述N为1，即第二时频资源上承载一个格式0的PUCCH，该PUCCH在频域上占用第二时频资源的两个符号，分别为第一符号和第二符号，其中第一符号与第一时频资源的时域重叠，第二符号与第一时域资源的时域不重叠，此时，终端设备可以发送第二符号上承载的信息，而不发送第一符号上承载的信息。由于第一符号和第二符号上承载的信息相同，因此在发送第二符号上承载的信息后，不再重新发送该PUCCH，进而避免该PUCCH的重复发送，从而节约了通信资源。
在一种实现方式中，上述终端设备调整N个上行信道的发送包括：当第一时间间隔小于第二时间间隔时，终端设备调整该N个上行信道的发送，该第一时间间隔为所述终端设备处理网络设备发送的指示信息所需要时间，该第二时间间隔为所述终端设备接收到该指示信息的时间与终端设备开始发送该N个上行信道的时间之间的时间间隔。
第二方面，本申请实施例提供了一种通信方法，应用于网络设备，该方法包括：网络设备向终端设备发送指示信息，该指示信息用于指示第一时频资源；当该第一时频资源与承载所述终端设备待发送的N个上行信道的第二时频资源重叠时，网络设备从所述终端设备接收所述第二时频资源中与所述第一时频资源不重叠的时频资源上承载的至少一个所述上行信道，其中，N为大于或等于2的正整数。
可选的，上述第二时频资源可以包括N个时间单元，每个时间单元承载一个所述 上行信道，每个所述上行信道承载相同的信息，所述N个时间单元中M个时间单元与所述第一时频资源重叠，所述N个时间单元中除所述M个时间单元以外的Q个时间单元与所述第一时频资源不重叠，其中，M，Q均为小于或等于N的正整数，且N为M与Q之和。
由于上行信道的调度方式不同，终端设备发送的上行信道会不同，对应的，网络设备接收到的上行信道也会不同。
第一种示例中，当所述上行信道是基于调度的上行信道，则上述网络设备从所述终端设备接收所述第二时频资源中与所述第一时频资源不重叠的时频资源上承载的至少一个所述上行信道，可以包括：网络设备接收所述Q个时间单元上承载的所述上行信道。
在第一种示例下，N个上行信道中的P个上行信道可以共享一个解调参考信号DMRS，其中，P为小于或等于Q的正整数。此时，本申请实施例的方法还可以包括：当承载所述P个上行信道中R个上行信道的时间单元属于所述Q个时间单元，且承载所述DMRS的时间单元属于所述M个时间单元，网络设备确定所述R个上行信道共享所述Q个时间单元中承载的第一个DMRS，其中，R为小于所述P的正整数。
在第二种示例中，当所述上行信道是免调度或免许可的上行信道，网络设备从所述终端设备接收所述第二时频资源中与所述第一时频资源不重叠的时频资源上承载的至少一个所述上行信道，可以包括：网络设备接收目标时间单元、以及所述N个时间单元中所述目标时间单元之后的时间单元上承载的所述上行信道，其中，该目标时间单元为所述Q个时间单元中第一个承载DMRS的时间单元。
可选的，本申请实施例中当第二时频资源中与第一时频资源不重叠的时频资源上承载的所述上行信道的数量小于P时，则丢失所述第二时频资源上承载的N个上行信道。
可选的，本申请实施例中的时间单元为迷你时隙，该迷你时隙包括的符号数小于14。
可选的，本申请实施例中的第一时频资源用于其他终端设备的上行传输。
在一种实现方式下，当上述第二时频资源的部分时频资源与第一时频资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠时，本申请实施例的方法还包括：在第二时频资源与第一时频资源时域不重叠的时频资源上接收N个上行信道承载的信息，该N为大于或等于1的正整数，N个上行信道是格式0的上行控制信道。

第二种示例中，当N大于或等于2时，上述第二时频资源包括N个时间单元，每个时间单元承载一个所述上行信道，每个所述上行信道承载相同的信息，所述N个时间单元中M个时间单元与所述第一时频资源重叠，所述N个时间单元中除所述M个时间单元以外的Q个时间单元与所述第一时频资源不重叠，其中，M，Q均为小于或等于N的正整数，且N为M与Q之和。

图2为本申请实施例一提供的通信方法的流程图，如图2所示，本申请实施例的方法可以包括：
S201、网络设备向终端设备发送指示信息。
其中，所述指示信息用于指示第一时频资源。
具体地，所述第一时频资源可以是网络设备向该终端设备以外的其他终端设备分配的时频资源，可以用于承载其他终端设备的上行传输的业务或数据。所述指示信息可以用于指示所述第一时频资源用于承载其他终端设备的上行传输的业务或数据。
可选的，本申请实施例的指示信息可以是上行抢占指示(UpLink Preemption Indication，UL PI)，或者为上行取消指示信息(Uplink cancelation)，用于指示其他终端设备用于上行传输的资源。
可选的，上述指示信息可以是组公共(group common)信令，能被同一服务小区或者同一带宽部分(Band Width Part，BWP)内所有的UE接收。
S202、当所述第一时频资源与承载所述终端设备待发送的N个上行信道的第二时频资源重叠时，终端设备调整所述N个上行信道的发送。
其中，所述N为正整数，即第二时频资源上承载1个或多个上行信道。
本申请实施例涉及的上行信道可以是用于承载上行数据的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，也可以为用于传输上行控制信息的物理上行控制信道(Physical Uplink Control Channel，PUCCH)，例如PUCCH format 0,1,2,3,4，还可以为传输初始接入前导(preamble)序列的物理初始接入信道(Physical Random Access Channel，PRACH)。
在一种示例中，本申请实施例可以适用于eMBB、URLLC和mMTC业务中任一相同业务在上行信道复用的场景，例如，适用于两种不同的eMBB业务在上行信道复用的场景，或者两种不同的URLLC业务在上行信道复用的场景，或者两种不同的mMTC业务在上行信道复用的场景。可选的，本申请实施例还适用于eMBB、URLLC和mMTC业务中任意两种不同业务在上行信道复用的场景，例如适用于eMBB业务和URLLC业务在上行信道复用的场景，该场景下，上述终端设备当前正在进行eMBB业务，而上述第一时频资源用于承载URLLC业务；或者适用于eMBB业务和mMTC业务在上行信道复用的场景，该场景下，上述终端设备当前正在进行eMBB业务，而上述第一时频资源用于承载mMTC业务；或者适用于URLLC业务和mMTC业务在上行信道复用的场景，该场景下，上述终端设备当前正在进行URLLC业务，而上述第一时频资源用于承载mMTC业务，或者，在该场景下，上述终端设备当前正在进行mMTC业务，而上述第一时频资源用于承载URLLC业务。其中，用于传输eMBB业务的终端设备记为eMBB UE，用于传输URLLC业务的终端设备记为URLLC UE，用于传输mMTC业务的终端设备记为mMTC UE。需要说明的是，上述各业务只是示例，本申请实施例适用的业务复用场景不局限于上述各业务的复用。
为了便于阐述，本申请以eMBB业务和URLLC业务在上行信道复用的场景为例进行说明，其他的业务参照即可。该场景下，上述终端设备当前正在进行eMBB业务，记为eMBB UE，而上述第一时频资源用于承载其他终端设备的URLLC业务，此处的其他终端设备记为URLLC UE。
URLLC业务对时延要求极高，不考虑可靠性的情况下，传输时延要求在0.5毫秒以内，在达到99.999％的可靠性的前提下，传输时延要求在1毫秒(ms)以内。
URLLC业务的数据包的产生具有突发性和随机性，可能在很长一段时间内都不会产生数据包，也可能在很短时间内产生多个数据包。URLLC业务的数据包在多数情况下为小包，例如50个字节。
在上行传输中，网络设备为终端设备，例如eMBB UE，调度了第二时频资源，该第二时频资源用于承载终端设备待发送的N个上行信道。此时，有突发的URLLC业务需要传输，URLLC UE会首先给网络设备发送调度请求(Scheduling Request，SR)。为了避免eMBB业务和URLLC业务在相同的时频资源上传输而产生对彼此的干扰，网络设备收到SR之后会发送指示信息给eMBB UE，该指示信息用于指示第一时频资源，该指示信息指示该第一时频资源用于承载其他终端设备，例如，URLLC UE，的上行传输。
而当指示信息指示的第一时频资源与URLLC业务实际传输所需的时频资源的大小如图3所示，即一个指示信息指示的第一时频资源大于URLLC业务实际传输所需的时频资源，此时一个指示信息指示的第一时频资源上不仅可以承载URLLC UE的上 行信道，例如承载URLLC PUSCH，还可能会承载eMBB UE的上行信道，例如承载eMBB PUSCH1、eMBB PUSCH2和已取消传输的eMBB PUSCH1等。其中，第一时频资源内具体哪部分时频资源用于承载URLLC业务可以由指示信息的DCI域中的比特来指示。
对于图3所示的第一时频资源和第二时频资源的关系可知，指示信息指示的第一时频资源与承载终端设备待发送的N个上行信道的第二时频资源之间可能存在重叠。特别地，当第二时频资源上只有一个待发送的上行信道，且第二时频资源的一部分与第一时频资源重叠，第二时频资源用于传输eMBB业务数据，此时，若在重叠的时频资源上即发送eMBB业务，又发送URLLC业务，可能会造成eMBB业务与URLLC业务相互影响。
为了解决该技术问题，本申请实施例，终端设备从网络设备接收指示信息，并根据该指示信息指示的第一时频资源，判断第一时频资源与第二时频资源之间是否重叠。若第一时频资源与第二时频资源重叠，则调整承载在第二时频资源上的N个上行信道的发送。
其中，第一时频资源与第二时频资源之间的重叠，如图4所示，可以是，第二时频资源的一部分时频资源与第一时频资源的一部分时频资源的时域和频域完全重叠，而另一部时频资源与第一时频资源的时域或者频域不重叠。或者第二时频资源的一部分时频资源与第一时频资源的时域和频域完全重叠，第二时频资源的另一部分与第一时频资源的频域或时域完全不同。或者，如图5所示，第二时频资源的全部时频资源与第一时频资源重叠，即第二时频资源全部位于第一时频资源中。
其中，本申请实施例中调整上行信道的发送包括不发送上行信道，或者暂停上行信道的发送，或者丢弃第二时频资源中与第一时频资源重叠的时频资源上承载的上行信道，且发送第二时频资源中与第一时频资源不重叠的时频资源上承载的一个或多个上行信道。
在第一种示例中，当第一时频资源与第二时频资源重叠时，为了防止承载在第二时频资源上的N个上行信道对承载在第一时频资源上的上行信息的干扰，如图6所示，则不发送承载在第二时频资源上的所有上行信道，即丢弃承载在第二时频资源上的N个上行信道，此时，N可以为大于或等于1的正整数。
在第二种示例中，当第一时频资源与第二时频资源重叠时，为了防止承载在第二时频资源上的N个上行信道对承载在第一时频资源上的上行信息的干扰，则暂时不发送承载在第二时频资源上的所有上行信道。待承载在第一时频资源上的上行信息发送结束后，再发送承载在第二时频资源上的N个上行信道。
在第三种示例中，当N大于或等于2，且第二时频资源中不与第一时频资源重叠的时频资源上至少承载一个上行信道。此时，为了防止承载在第二时频资源上的N个上行信道对承载在第一时频资源上的上行信息的干扰，如图7所示，可以暂时不发送第二时频资源中与第一时频资源重叠的时频资源上承载的上行信道(即图7中阴影部分上承载的上行信道)，并发送第二时频资源中不与第一时频资源重叠的时频资源上承载的上行信道。待第一时频资源中与第二时频资源重叠的时频资源上承载的上行信息发送结束后，发送第二时频资源中与第一时频资源重叠的时频资源上承载的上行信 道。
在第四种示例中，当N大于或等于2，且第二时频资源中不与第一时频资源重叠的时频资源上至少承载一个上行信道。此时，为了防止承载在第二时频资源上的N个上行信道对承载在第一时频资源上的上行信息的干扰，如图7所示，可以丢弃第二时频资源中与第一时频资源重叠的时频资源上承载的上行信道，并发送第二时频资源中不与第一时频资源重叠的时频资源上承载的上行信道。
第五种示例，当N等于1，且第二时频资源的部分时频资源与所述第一时频资源重叠，所述第二时频资源的剩余部分时频资源与所述第一时频资源不重叠。此时，为了防止承载在第二时频资源上的N个上行信道对承载在第一时频资源上的上行信息的干扰，则丢弃第二时频资源上承载的该上行信道。
在第六种示例中，当第二时频资源的一部分时频资源与第一时频资源的一部分时频资源重叠，而另一部时频资源与第一时频资源不重叠，且第二时频资源上承载一个上行信道，或者，第二时频资源上传承载的N个上行信道上承载的信息不同。此时，为了防止承载在第二时频资源上的N个上行信道对承载在第一时频资源上的上行信息的干扰，终端设备重新组包，不改变原承载在第二时频资源上一个上行信道，或原承载在第二时频资源上的N个上行信道的传输块大小(即承载的比特数)，减小承载该一个上行信道或承载该N个上行信道的时频资源。具体可以通过调整调制编码方式(Modulation and Coding Scheme，MCS)来调整时频资源的大小，具体地可以通过提高码率，或者改变调制方式，增大调制符号上承载的比特数来实现，例如将正交相移键控(Quadrature Phase Shift Keyin，QPSK)调制方式调整为16正交振幅调制(Quadrature Amplitude Modulation，QAM)，或者将16QAM调整为64QAM。这样，将经过重新组包后的一个上行信道或N个上行信道承载在第二时频资源中不与第一时频资源重叠的时频资源上发送。
可选的，由于指示信息是网络设备发送的，N个上行信道所占用的第二时频资源也是由网络设备调度的，因此，网络设备知道指示信息指示的第一时频资源和第二时频资源有重叠，这样，网络设备在向终端设备发送指示信息的同时，也可以发送一个新的上行调度(UL grant)信令给终端设备，该新的上行调度信令用于指示终端设备在不与第一时频资源重叠的时频资源上发送这N个上行信道。
本申请实施例的通信方法，网络设备向终端设备发送指示信息，终端设备接收到该指示信息后，判断该指示信息指示的第一时频资源与承载该终端设备待发送的N个上行信道的第二时频资源是否重叠，当终端设备判断第一时频资源与第二时频资源重叠，则调整N个上行信息的发送。以优先发送承载在第一时频资源上的信息，进而避免第一时频资源与第二时频资源重叠时，第二时频资源上承载的信息对第一时频资源上承载的信息的干扰，进而提升第一时频资源上信息的传输效率与传输质量。例如，在eMBB业务和URLLC业务并行的应用场景中，可以优先且完整传输URLLC业务，提升URLLC业务的传输质量。
图8为本申请实施例二提供的通信方法的流程图，在上述实施例的基础上，当本申请实施例的第二时频资源包括N个时间单元，每个时间单元承载一个所述上行信道， 每个所述上行信道承载相同的信息，所述N个时间单元中M个时间单元与所述第一时频资源重叠，且，所述N个时间单元中除所述M个时间单元以外的Q个时间单元与所述第一时频资源不重叠时，如图8所示，本申请实施例的方法可以包括：
S301、网络设备向终端设备发送指示信息，所述指示信息用于指示第一时频资源。
所述第一时频资源可以是网络设备为其他终端设备分配的时频资源，具体描述参照本申请其他实施例的相关描述，不做赘述。
S302、当所述第一时频资源与承载所述终端设备待发送的N个上行信道的第二时频资源的部分时频资源重叠时，终端设备向网络设备发送所述第二时频资源中与所述第一时频资源不重叠的时频资源上承载的至少一个所述上行信道。
需要说明的是，本申请实施例涉及的N为大于或等于2的正整数，M和Q为小于或等于N的正整数，且M+Q＝N，P为小于或等于Q的正整数，R为小于P的正整数。
本申请实施例中，第二时频资源包括N个时间单元，每个时间单元承载一个所述上行信道，每个所述上行信道承载相同的信息，所述N个时间单元中M个时间单元与所述第一时频资源重叠，所述N个时间单元中除所述M个时间单元以外的Q个时间单元与所述第一时频资源不重叠。可以理解，上述N个时间单元与S202中描述的N个上行信道的数量是相同的，即一个时间单元承载一个上行信道。
具体的，如图9所示，本申请实施例的第二时频资源包括N个时间单元，每个时间单元由一个或多个符号组成，每个时间单元上承载一个上述实施例中的上行信道，这样，N个时间单元共承载N个上行信道。其中，每个上行信道上承载的信息相同，例如N个上行信道均为相同的PUSCH。这样，在第二时频资源上重复发送N个上行信道，提高了上行信道的发送可靠性。
可选的，本申请实施例的时间单元可以为迷你时隙，每个迷你时隙包括的符号数小于14。
采用迷你时隙(mini-slot)(也称为非基于时隙(non-slot-based))的时域调度粒度，每个迷你时隙由一个或多个符号组成，例如为2,3,4,5,6,7,8,9,10,11,12,13个符号，可选的，该符号可以为正交频分复用((Orthogonal Frequency Division Multiplexing，OFDM)符号。基于迷你时隙的调度可以满足小包(通常为32byte即256bits为一个小包)发送，满足低时延的特征。为了满足可靠性，本申请实施例基于迷你时隙的重复(mini-slot based PUSCH repetition)的方法，在第二时频资源上重复发送N个相同的上行信道，提高了上行信道的发送可靠性。
可选的，本申请实施例的时间单元包括的符号数小于14。例如，本申请实施例的时间单元可以为1个符号的mini-slot、2个符号的mini-slot、4个符号的mini-slot，……，或者14个符号的mini-slot。对应的，第二时频资源上承载的上行信道最多可以为13个，最少可以为1个。
基于迷你时隙的重复可以是基于调度的(grant-based)，也可以是免许可的或者免调度或免许可的(grant-free/configured grant)。
当上行信道是基于调度的上行信道时，S302可以包括：丢弃所述M个时间单元上承载的所述上行信道；发送所述Q个时间单元上承载的所述上行信道。
对应的，网络设备接收终端设备发送的所述第二时频资源中与所述第一时频资源不重叠的时频资源上承载的至少一个所述上行信道，可以包括：接收所述Q个时间单元上承载的所述上行信道。
本申请实施例中，基于mini-slot based PUSCH repetition的第二时频资源和上行调度指示信息(UL grant)，以及混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)的进程号都是由DCI动态指示的。即网络设备指示了第二时频资源中每个时间单元包括的符号数。
如图10所示，第二时频资源的N个时间单元中，有M个时间单元与第一时频资源重叠，有Q个时间单元与第一时频资源不重叠。此时，如图11所示，上述S302可以包括：丢弃M个时间单元上承载的上行信道，并发送Q个时间单元上承载的上行信道，进而避免第二时间资源上承载的上行信道对第一时频资源上承载的信息的干扰，提高了第一时频资源上承载的信息的发送可靠性。同时，通过在第二时频资源上承载相同的多个上行信道，发送Q个时间单元上承载的上行信道，保证了至少一个上行信道的传输，进而提高了通信的可靠性以及通信系统的通信效率。
可选的，本申请实施例中N个时间单元中M个时间单元与所述第一时频资源重叠，可以是，M个时间单元中的每个时间单元完全属于第一时频资源。
可选的，如图10所示，本申请实施例中N个时间单元中M个时间单元与所述第一时频资源重叠，可以是，M个时间单元中的至少一个时间单元中的部分符号属于第一时频资源，部分符号不属于第一时频资源。例如，第M个时间单元所在的部分符号属于第一时频资源，部分符号不属于第一时频资源。
在第一种示例中，本申请实施例中每个上行信息对应一个解调参考信号(Demodulation reference signal，DMRS)。
在第二种示例中，所述N个上行信道中的P个上行信道共享一个DMRS，所述P为小于或等于Q的正整数。
在第二种示例的基础上，本申请实施例还包括：当承载所述P个上行信道中R个上行信道的时间单元属于所述Q个时间单元，且承载所述DMRS的时间单元属于所述M个时间单元，确定所述R个上行信道共享所述Q个时间单元中承载的第一个DMRS，其中，所述R为小于所述P的正整数。
可选的，本申请实施例中当第二时频资源中与第一时频资源不重叠的时频资源上承载的所述上行信道的数量小于P时，则丢失所述第二时频资源上承载的N个上行信道。
具体的，在基于迷你时隙的重复调度中，每个时隙中有1～2个符号用于承载解调参考信号(demodulation reference signals，DMRS)。而基于非时隙或迷你时隙的传输调度的单位较小，一般为2、4或者7个符号。1～2个符号的DMRS对于非时隙或迷你时隙调度来说开销过大。因此，一种共享DMRS(DMRS sharing)的方法被提出。具体地，不为每个上行信道配置或者调度DMRS，而是为一个上行信道配置或调度DMRS，若干个上行信道共享此DMRS，即N个上行信道中的P个上行信道共享一个DMRS。网络设备接收到此DMRS后对P个上行物理信道进行信道估计，以便正确解调承载在P个上行信道承载的数据块。例如，如图12所示，两个上行信道共享一个 DMRS，网络设备可以根据接收到的一个DMRS，解调该DMRS后的两个上行信道。
举例说明，如图12，假设上行信道1和上行信道2共享一个DMRS1，承载上行信道1的为时间单元1，承载上行信道2的为时间单元2，且DMRS1承载在时间单元1上。而时间单元1上承载的DMRS1的符号正好与第一时频资源重叠，而上行信道2上承载的时间单元2与第一时频资源不重叠。此时，发送上行信道2，而丢弃DMRS1，这样，使得上行信道2没有对应的DMRS1。此时，时间单元2后用于承载DMRS2的时间单元3与第一时频资源不重叠，即承载在时间单元3上的DMRS2发送，这样，可以确定上行信道2共享该DMRS2。也就是说，第二时频资源上承载的多个DMRS是相同，可以被相同的上行信道共享。
本申请实施例的方法，当上行信道是基于调度的上行信道时，终端设备丢弃所述M个时间单元上承载的所述上行信道并发送所述Q个时间单元上承载的所述上行信道。对应的，网络设备接收Q个时间单元上承载的所述上行信道，进而实现对承载在第一时频资源上的上行信道的准确发送的同时，传输第二时频资源上承载的至少一个上行信道，进一步提高了通信系统的上行传输可靠性和传输效率。
当上行信道是基于免调度或免许可的上行信道时，上述S302可以包括：从所述Q个时间单元中确定第一个承载DMRS的目标时间单元，丢弃所述N个时间单元中所述目标时间单元之前的时间单元上承载的所述上行信道，并发送所述目标时间单元、以及所述N个时间单元中所述目标时间单元之后的时间单元上承载的所述上行信道。
对应的，网络设备接收终端设备发送的所述第二时频资源中与所述第一时频资源不重叠的时频资源上承载的至少一个所述上行信道，可以包括：网络设备接收目标时间单元、以及所述N个时间单元中所述目标时间单元之后的时间单元上承载的所述上行信道，其中，所述目标时间单元为所述Q个时间单元中第一个承载DMRS的时间单元。
本申请实施例中，网络设备为终端设备配置免调度或免许可资源，终端设备可以在免调度或免许可资源上给网络设备发送对时延要求较高的业务，例如URLLC业务。由于URLLC业务的控制和数据信息要求低时延，端到端时延可低至0.5ms，通过网络设备传输下行调度信息后，终端设备再根据调度信息进行上行传输无法满足这种时延要求，所以URLLC UE或者支持URLLC业务也支持其他类型业务的终端设备可以通过免调度或免许可资源发送上行信息。
但是，网络设备在接收到免调度或免许可的上行信道之前，对于该上行信道所占的时频资源和传输数据量大小，以及HARQ进程号等信息一无所知。当免调度或免许可的mini-slot PUSCH repetition中的N个时间单元中，有M个时间单元与所述第一时频资源重叠，有Q个时间单元与所述第一时频资源不重叠，则不发送不与第一时频资源重叠的第一个DMRS之前的时间单元上承载的上行信道，即从不与第一时频资源重叠的第一个DMRS所在时间单元开始传输。
具体的，如图12所示，当第二时频资源包括的N个时间单元中，有M个时间单元与所述第一时频资源重叠，有Q个时间单元与所述第一时频资源不重叠，且上行信道是基于免调度或免许可的上行信道时，则如图13所示，从所述Q个时间单元中确 定第一个承载DMRS的目标时间单元，丢弃所述N个时间单元中所述目标时间单元之前的时间单元上承载的所述上行信道，并发送所述目标时间单元、以及所述N个时间单元中所述目标时间单元之后的时间单元上承载的所述上行信道。这样，网络设备能够根据接收到的DMRS准确解调该DMRS之后的上行信道，保证了上行信道解析的准确性。
可选的，本申请实施例的终端设备从冗余版本(redundancy version，RV)为0的上行信息开始发送。由于grant free传输业务是随机而来的，当冗余序列为(0，2，3，1)时，规定第一个发送的上行信道是RV为0的那一个，则网络设备只需要在RV为0的位置开始盲检，而不需要在0,2,3,1都盲检，从而可以降低网络设备盲检测的复杂度。另外，只从RV为0的上行信道开始发送的传输效率也比较高。因为只有接收到全部信息的比特位后，网络设备才能成功解调数据。
本申请实施例提供的通信方法，第二时频资源中的N个时间单元中，M个时间单元与第一时频资源重叠，N个时间单元中除M个时间单元以外的Q个时间单元与第一时频资源不重叠，此时，当上行信道是基于调度的上行信道，则终端设备丢弃M个时间单元上承载的所述上行信道，并发送Q个时间单元上承载的上行信道。当上行信道是基于免调度或免许可的上行信道，则终端设备首先从Q个时间单元中确定第一个承载DMRS的目标时间单元，并丢弃N个时间单元中目标时间单元之前的时间单元上承载的所述上行信道，发送目标时间单元、以及N个时间单元中目标时间单元之后的时间单元上承载的上行信道，进而根据不同的情况，避免第二时频资源上承载的信息对第一时频资源上承载的信息产生干扰的基础上，实现对承载在第一时频资源上的上行信息的准确发送的同时，传输第二时频资源上承载的至少一个上行信道，进一步提高了通信系统的上行传输可靠性和传输效率。
图14为本申请一实施例提供的通信方法流程图，在上述实施例的基础上，若上述N个上行信道是格式0的PUCCH，则本申请实施例的方法可以包括：
S401、网络设备向终端设备发送指示信息，所述指示信息用于指示第一时频资源。
所述第一时频资源可以是网络设备为其他终端设备分配的时频资源，具体描述参照上述S201实施例的相关描述，不做赘述。
S402、当第二时频资源的部分时频资源与第一时频资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠时，终端设备在第二时频资源与第一时频资源时域不重叠的时频资源上发送上述N个上行信道承载的信息，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信息发送。
本步骤中，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信息发送，可以理解为不发送第二时频资源中与第一时频资源时域重叠的时频资源上的信息，或者理解为丢弃第二时频资源中与第一时频资源时域重叠的时频资源上的信息。
本步骤中，第二时频资源的部分时频资源与第一时频资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠可以包括图15和图4所示两种情况。如图15所示，当第一时频资源的全部时域资源与第二时频资源的部分时域资源重叠，即第一时域资源属于第二时域资源，且第二时域资源大于第一时域资源。如图4所示， 当第二时频资源的部分时频资源与第一时频资源的部分时域资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠。
PUCCH的格式包括格式0,1,2,3,4，假设第二时频资源上承载一个PUCCH。对于格式1和格式4的PUCCH，通常使用正交覆盖码(orthogonal cover code，OCC)对时域资源上承载的信息进行正交处理。若该格式1或格式4的PUCCH在时域上占用第二时域资源的多个符号，该多个符号中的部分符号与第一时频资源重叠，剩余部分符号与第一时频资源不重叠。此时，为了保证PUCCH承载信息的正交性，则终端设备丢弃该PUCCH，即不发送该PUCCH。
对于格式2和格式3的PUCCH，其中格式2的PUCCH在时域上可以包括1个或2个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，格式3的PUCCH在时域上可以包括4个到14个OFDM符号。由于格式2或格式3的PUCCH的各符号上承载的信息不相同，若格式2或格式3的PUCCH在时域上占用第二时频资源的多个符号，该多个符号中的部分符号与第一时频资源不重叠，剩余部分符号与第一时频资源不重叠，此时，为了保证该PUCCH上承载信息的发送完整性，则终端设备丢弃该PUCCH，即不发送该PUCCH。
对于格式0的PUCCH，该PUCCH用于传输正向或负向调度请求信息(scheduling request，SR)，或者用于传输反馈信息混合自动重复请求响应(Hybrid Automatic Repeat Request-Acknowledgement，HARQ-ACK)，且传输信息的比特数为1或2bit。格式0的PUCCH传输占用的符号数为2，即PUCCH承载在第二时域资源的第一符号和第二符号上，第一符号和第二符号上传输的信息相同。此时，如图16所示，当第一个符号与第一时频资源重叠，而第二个符号与第一时频资源不重叠时，第二符号上的信息可以正常发送，这样可以避免该格式0的PUCCH的重传，进而节约了通信资源。
因此，当第二时频资源上承载N个格式0的PUCCH，同一个格式0的PUCCH的每个符号上承载的信息相同时，终端设备可以在第二时频资源与第一时频资源时域不重叠的时频资源上发送该N个PUCCH上承载的信息，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信息。
第一种情况，N＝1，即第二时域资源上承载一个格式0的PUCCH，如图16所示，该PUCCH在时域上占用第二时频资源的2个符号，记为第一符号和第二符号，其中，第一个符号与第一时频资源重叠，第二个符号与第一时频资源不重叠。在该情况下，终端设备不发送第一个符号上承载的信息，且发送第二个符号上承载的信息。由于第一符号和第二符号上承载的信息相同，因此在发送第二符号上承载的信息后，不再重新发送PUCCH，进而避免PUCCH的重复发送，从而节约了通信资源。
第二种情况是，N为大于等于2的正整数，假设N为3，即第二时频资源上承载3个格式0的PUCCH，每个格式0的PUCCH在时域上占用第二时频资源的2个符号。示例性的，如图17所示，第一PUCCH完全与第一时域资源重叠，第二PUCCH中的第一符号与第一时频资源部分或全部重叠，第二PUCCH中的第二符号与第一时频资源完全不重叠，第三PUCCH与第一时域资源完全不重叠。在这种情况下，终端设备可以发送第三PUCCH以及第二PUCCH中的第二符号上承载的信息，而不发送第一PUCCH以及第二PUCCH中的第一符号上承载的信息。
在该第二种情况的另一种示例中，如图18所示，第一PUCCH完全与第一时域资源重叠，第二PUCCH中的第一符号与第一时频资源完全重叠，第二PUCCH中的第二符号的部分与第一时频资源重叠，第二PUCCH中的第二符号的剩余部分与第一时频资源不重叠，第三PUCCH与第一时域资源完全不重叠。在这种情况下，终端设备可以发送第三PUCCH上承载的信息，而不发送第一PUCCH以及第二PUCCH上承载的信息。
本申请实施例提供的通信方法，当第二时域资源承载N个格式0的PUCCH，由于同一个格式0的PUCCH的各符号上承载的信息也相同，这样在第二时频资源与第一时频资源时域不重叠的时频资源上发送N个PUCCH的信息，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信息发送，实现在不影响其他传输的前提下，避免该PUCCH的重传，提高了通信系统的传输效率，节约了通信资源。
需要说明的是，上述各实施例中，终端设备调整N个上行信道的发送包括：当第一时间间隔小于第二时间间隔时，终端设备调整该N个上行信道的发送，该第一时间间隔为所述终端设备处理网络设备发送的指示信息所需要时间，该第二时间间隔为所述终端设备接收到该指示信息的时间与终端设备开始发送所述N个上行信道的时间之间的时间间隔。例如，上述N个上行信道为一个格式0的PUCCH，该第二时间间隔为终端设备从网络设备处接收到该指示信息的时间与终端设备开始发送该PUCCH的时间之间的时间间隔。
在一个示例中，假设上述N个上行信道为一个格式0的PUCCH，终端设备在时间a从网络设备处接收到指示第一时域资源的指示信息，接着对该指示信息进行处理，假设处理该指示信息所需要的时间为b，即第一时间间隔为b。该第二时间间隔为终端设备从网络设备处接收到该指示信息的时间a与终端设备开始发送该PUCCH的时间c之间的时间间隔，即第二时间间隔为c-a。为了能够及时终止PUCCH的一部分或整个PUCCH的发送，则指示信息的处理需要在PUCCH开始发送之前完成，即c-a大于b。
图19为本申请实施例提供的通信方法流程图，在上述实施例的基础上，若第二时域资源上承载N个上行信号，则本申请实施例的方法可以包括：
S501、网络设备向终端设备发送指示信息，所述指示信息用于指示第一时频资源。
所述第一时频资源可以是网络设备为其他终端设备分配的时频资源，具体描述参照上述S201实施例的相关描述，不做赘述。
S502、当第二时频资源的部分时频资源与第一时频资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠时，终端设备在第二时频资源与第一时频资源时域不重叠的时频资源上发送该N个上行信号，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信号发送。
本步骤中，第二时频资源的部分时频资源与第一时频资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠可以包括图15和图4所示两种情况。如图15所示，当第一时频资源的全部时域资源与第二时频资源的部分时域资源重叠，即第一时域资源属于第二时域资源，且第二时域资源大于第一时域资源。如图4所示， 当第二时频资源的部分时频资源与第一时频资源的部分时域资源重叠，且第二时频资源的剩余部分的时频资源与第一时频资源不重叠。
需要说明的是，上述N个上行信号相同，每个上行信号在时域上占用第二时频资源的多个符号，每个符号上承载的信息也相同。此时，为了防止上行信号的重复发送，终端设备在第二时频资源与第一时频资源时域不重叠的时频资源上发送该N个上行信号，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信号发送，进而提高了系统的传输效率。
可选的，上述N个上行信号为SRS，SRS主要用于上行信道质量的估计，基站的调度器可以根据上行信道状态估计，将瞬时信道状态好的资源块(Resource Block，RB)分配给终端设备的上行PUSCH传输。SRS还可以用于估计上行定时，上行波束管理等。在频域上，SRS可以覆盖调度器感兴趣的频带，可以发送多个“窄带SRS”并在频域上进行跳频，然后将一连串发送的SRS联合起来就能覆盖整个感兴趣的频带。这样可以将可用的传输功率集中在更窄的频率范围内，并在频带内进行跳频，获得频率增益。
SRS在一个时隙内的符号间可以重复发送，

为高层信令配置的一个时隙中SRS所占的OFDM符号数量，R为高层信令配置的SRS在时隙内重复的次数，
Figure PCTCN2019108482-appb-000002
在一种示例中，若上述N为1，即第二时频资源上承载一个上行信号，例如承载一个SRS，该SRS在频域上占用第二时频资源的多个符号，例如图20所示，SRS在频域上占用第二时域资源的K个符号，其中K个符号中的K1个符号与第一时域资源重叠，K个符号中除K1个符号外的K2个符号与第一时域资源不重叠，K1与K2之和等于K。在该情况下，终端设备可以发送K2个符号上承载的信号，而不发送该K1个符号上承载的信号。由于上述K个符号中每个符号上承载的信号相同，因此在发送上述K2个符号上承载的信号，即可实现该SRS的发送，这样可以避免SRS的重复发送，从而节约了通信资源。
如图20所示，SRS中的符号K1与第一时频资源的重叠包括两种情况：情况一，该符号K1全部位于第一时频资源中，即符号K1与第一时频资源完全重叠；情况二，该符号K1部分位于第一时频资源中，符号K1的剩余部分位于第一时频资源外。
需要说明的是，上述终端设备调整N个上行信号的发送包括：当第三时间间隔小于第四时间间隔时，终端设备调整该N个上行信号的发送，该第三时间间隔为所述终端设备处理网络设备发送的指示信息所需要时间，该第四时间间隔为所述终端设备接收到该指示信息的时间与终端设备开始发送该N个上行信号的时间之间的时间间隔。
本申请实施例提供的通信方法，当第二时域资源上承载N个上行信号，该N个上行信号相同，每个上行信号在时域上占用第二时频资源的多个符号，每个符号上承载的信息也相同，且第二时域资源与第一时域资源部分重叠，第二时域资源与第一时域资源部分不重叠时，终端设备在第二时频资源与第一时频资源时域不重叠的时频资源上发送该N个上行信号，静默第二时频资源中与第一时频资源时域重叠的时频资源上的信号发送，进而避免上行信号的重传，提高了系统的传输效率。
