Description

通信方法及装置
本申请要求于2018年05月11日提交国家知识产权局、申请号为201810450801.6、申请名称为“通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，并且更具体地，涉及一种通信方法及装置。
背景技术
在诸如长期演进(long term evolution，LTE)/长期演进增强(LTE advanced，LTE-A)等第4代(4th generation，4G)移动通信系统中，用户设备(user equipment，UE)根据基站(evolved Node B，eNB)配置的探测参考信号(sounding reference signal，SRS)资源，周期性地或非周期性地向eNB发送SRS，以便eNB完成上行信道测量和上行资源调度。然而，若基站为同一UE配置多个SRS资源，且上述多个SRS资源在同一子帧内，则该UE会认为上述多个SRS资源冲突，从而放弃在该子帧发送SRS，导致原本用于发送SRS的资源闲置，降低了资源利用率，且对上行信道测量和上行资源调度造成不良影响。
在诸如新的无线接入技术(new radio access technology,NR)等第5代(5th generation，5G)移动通信系统中，UE也会根据基站(g Node B，gNB)配置的SRS资源，周期性地，半持续性地，或非周期性地向eNB发送SRS。其中，gNB配置的SRS资源可以是至少一个SRS资源集合，每个SRS资源集合均可包括至少一个SRS资源。目前，SRS资源集合可以采用如下类型(setUse)之一：基于码本(codebook，CB)的SRS资源集合、基于非码本(non-codebook，NCB)的SRS资源集合、用于波束管理(beam management，BM)的SRS资源集合和用于天线切换(Antenna Switching,AS)的SRS资源集合。从技术本身而言，NR能够支持BM、时隙(slot)内AS等技术，即同一UE是可以在同一时隙内不同SRS资源上同时发送SRS的，只要保证不同SRS资源中的时域资源、频域资源和码域资源中的至少一项能够区分即可。然而，现有NR协议版本R15(release 15)并未区分上述各种场景，而是一律放弃在同一时隙发送SRS，即NR也存在与LTE/LTE-A类似的问题。
发明内容
本申请提供一种通信方法及装置，以期适用于通信系统中资源冲突时用于上行信道质量测量的上行信号收发。
第一方面，提供了一种通信方法，包括：终端接收第一探测参考信号SRS配置信息和第二SRS配置信息，并确定第一SRS资源与第二SRS资源在时间单元内是否冲突。即使冲突，终端也可以确定在该时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上发送SRS。其中，第一SRS配置信息用于指示终端在第一SRS资源上发 送SRS，第二SRS配置信息用于指示终端在第二SRS资源上发送SRS，时间单元包括：时隙或符号。
可选的，当时间单元为符号时，终端还可以确定在所述时间单元所在的时隙内除所述时间单元以外的符号上，不在所述第一SRS资源和第二SRS资源中的一个SRS资源之外的另一个SRS资源上传输SRS，即所述终端确定在所述时间单元所在的时隙内仅在所述第一SRS资源和第二SRS资源中的一个SRS资源上传输SRS，或者说所述终端确定在所述时间单元所在的时隙内，不在所述第一SRS资源和第二SRS资源中的一个SRS资源之外的另一个SRS资源上传输SRS。
或者所述终端不认为会收到配置了第一SRS资源与第二SRS资源在时间单元内冲突的第一配置信息和第二配置信息。可选的，当终端收到所述配置了第一SRS资源与第二SRS资源在时间单元内冲突的第一配置信息和第二配置信息时，终端确定所述第一配置信息和所述第二配置信息为错误的配置信息。
由此可见，即使第一SRS资源与第二SRS资源在时间单元内冲突，终端也能够在该时间单元内，在第一SRS资源和第二SRS资源中的一个资源上发送SRS，避免了在该时间单元内第一SRS资源和第二SRS资源均被闲置的情况，能够提高SRS资源的利用效率和SRS的传输效率，从而提高了上行信道的测量效率和上行资源的调度效率。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第一时域冲突条件，且第一SRS资源集合和第二SRS资源集合中的至少一个为用于天线切换AS的资源集合。其中，第一时域冲突条件为：第一SRS资源所包括的至少一个时隙与第二SRS资源所包括的至少一个时隙相同，时间单元为时隙。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。其中，第一SRS资源集合与第二SRS资源集合可以分别为以下一种类型的SRS资源集合：基于码本CB的SRS资源集合、基于非码本NCB的SRS资源集合、用于波束管理BM的SRS资源集合和用于天线切换AS的SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第一类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第一类型冲突条件为：第一SRS资源集合和第二SRS资源集合为不同类型的SRS资源集合。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第二类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第二类型冲突条件为：第一SRS资源集合与第二SRS资源集合均为用于天线切换AS的SRS资源集合。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS 资源与第二SRS资源满足第二时域冲突条件和第三类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第三类型冲突条件为：第一SRS资源集合为用于波束管理BM的SRS资源集合，第二SRS配置信息中的空间关系信息所指示的第三SRS资源属于第一SRS资源集合，且第三SRS资源与第一SRS资源不同。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第四类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第四类型冲突条件为：第一SRS配置信息中的空间关系信息所指示的第四SRS资源与第二SRS配置信息中的空间关系信息所指示的第五SRS资源不同，且第四SRS资源与第五SRS资源属于同一个SRS资源集合，且同一个SRS资源集合为用于波束管理的SRS资源集合。
可选的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源和第二SRS资源同时满足第二时域冲突条件、频域冲突条件和码域冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。频域冲突条件为：第一SRS资源和第二SRS资源包括至少一个相同子载波；码域冲突条件为：第一SRS资源和第二SRS资源包括至少一个具有相同循环移位的SRS序列。
可选的，终端确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上发送SRS，可以包括：若终端确定第一SRS资源的优先级高于第二SRS资源的优先级，则终端确定在时间单元内，在第一SRS资源上发送SRS，从而能够保证高优先级SRS资源优先用于传输SRS。其中，SRS资源的优先级可以根据SRS资源所属SRS资源集合的类型(基于CB的SRS资源集合、基于NCB的SRS资源集合、用于BM的SRS资源集合、用于AS的SRS资源集合)、SRS发送方式(周期性、半持续性、非周期性)、SRS资源所包括的时隙数量或符号数量、调度时间(接收到触发非周期SRS的DCI的时间)或激活时间(接收到激活半持续SRS的MAC CE的时间)等至少一个因素确定。应理解，影响SRS资源优先级的因素，还可以包括除上述因素之外的其他因素，本申请不再一一列举。
示例性的，可以为对上行信道测量和上行资源调度具有更大影响的SRS资源设置更高的优先级。例如，用于BM的SRS资源集合所包括的SRS资源的优先级，通常高于上述其他3种类型的SRS资源集合所包括的SRS资源的优先级。又例如，可以为同一时隙内占用符号数量较多的SRS资源的优先级，通常高于同一时隙内占用符号数量较少的SRS资源的优先级。
示例性的，也可以为对上行信道测量和上行资源调度的时效性要求较高的SRS资源设置较高的优先级。例如，采用非周期性(aperiodic，AP)发送方式的SRS资源的优先级高于采用半持续性(semi-persistent，SP)发送方式的SRS资源的优先级，且采用半持续性发送方式的SRS资源的优先级高于采用周期性(periodic，P)发送方式的SRS资源的优先级。
示例性的，不同的SRS资源的优先级还可以根据不同的SRS资源的调度时间或激活时间的先后顺序来确定。例如，调度时间或激活时间在后的SRS资源的优先级高于调度时间或激活时间在前的SRS资源的优先级。
应理解，SRS资源的优先级可以根据一个因素确定，也可以根据多个因素综合确定，比如，既考虑时效性要求又考虑调度时间或激活时间的顺序。例如，可以首先根据SRS发送方式将SRS资源分为非周期性组、半持续性组和周期性组，非周期性组、半持续性组和周期性组的优先级依次从高到低。然后，针对每个分组，根据该分组所包括的所有SRS资源的调度时间或激活时间的先后顺序确定该分组内每个SRS资源的优先级。
可选的，该通信方法还可以包括：终端接收第三SRS配置信息。其中，第三SRS配置信息用于指示终端在第六SRS资源上发送SRS。然后，终端确定在时间单元内，第六SRS资源与第二SRS资源冲突，且与第一SRS资源不冲突。相应的，终端确定在时间单元内，在第一SRS资源上发送SRS，可以包括：终端确定在时间单元内，在第一SRS资源上和第六SRS资源上发送SRS。
可选的，该通信方法还可以包括：终端上报可在同一个符号内发送SRS的资源数量或端口数量，以便网络设备依据上述资源数量或端口数量为该终端确定SRS配置信息，从而保证配置的同时传输的SRS资源或端口数量不超过终端所能支持的最大数量，因此可以降低不同SRS配置信息所指示的SRS资源冲突的概率，从而进一步提高了SRS资源的利用效率和SRS的传输效率。
第二方面，提供了一种通信方法，包括：网络设备发送第一探测参考信号SRS配置信息和第二SRS配置信息。其中，第一SRS配置信息用于指示终端在第一SRS资源上发送SRS，第二SRS配置信息用于指示终端在第二SRS资源上发送SRS。之后，若第一SRS资源与第二SRS资源在时间单元内冲突，则网络设备确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上接收SRS。其中，时间单元包括：时隙或符号。
由此可见，即使第一SRS资源与第二SRS资源在时间单元内冲突，网络设备也能够在该时间单元内，在第一SRS资源和第二SRS资源中的一个资源上接收SRS，避免了在该时间单元内第一SRS资源和第二SRS资源均被闲置的情况，能够提高SRS资源的利用效率和SRS的传输效率，从而提高了上行信道的测量效率和上行资源的调度效率。
可以理解，第一SRS配置信息和第二SRS配置信息是由网络设备确定并发送的，即网络设备也具备第一方面及其可选方案中所述的第一SRS资源与第二SRS资源是否冲突的判断能力。因此，网络设备能够根据判断结果只在不冲突的SRS资源上接收SRS，以减少网络设备的计算工作量，从而进一步提高SRS的传输效率和上行资源的调度效率。
可以理解，网络设备也可以根据已发送的SRS配置信息，确定待发送SRS配置信息，以避免两个SRS配置信息所指示的SRS资源冲突。
可以理解，在网络设备确定第一SRS资源与第二SRS资源在时间单元内冲突时，也可以根据终端侧相同的通信方法确定第一SRS资源和第二SRS资源的优先级，并根 据确定的优先级确定SRS接收方案。因此，相应的，网络设备确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上接收SRS，可以包括：网络设备确定第一SRS资源的优先级高于第二SRS资源的优先级，且在时间单元内，在第一SRS资源上接收SRS。
可选的，在网络设备确定在时间单元内，该通信方法还包括：网络设备发送第三SRS配置信息。其中，第三SRS配置信息用于指示终端在第六SRS资源上发送SRS。然后，网络设备确定在时间单元内，第六SRS资源与第二SRS资源冲突，且与第一SRS资源不冲突，以及第二SRS资源的优先级高于第六SRS资源的优先级。相应地，网络设备确定在时间单元内，在第一SRS资源上接收SRS，可以包括：网络设备在时间单元内，在第一SRS资源上和第六SRS资源上接收SRS。
可选的，与第一方面所述的终端上报可在同一个符号内发送SRS的资源数量或端口数量相对应，该通信方法还包括：网络设备接收终端可在同一个符号内发送SRS的资源数量或端口数量，并依据上述资源数量或端口数量为该终端确定SRS配置信息，降低不同SRS配置信息所指示的SRS资源冲突的概率，从而进一步提高SRS资源的利用效率和SRS的传输效率。
第三方面，提供了一种通信方法，包括：终端接收第一配置信息和第二配置信息。其中，第一配置信息用于指示终端在第一资源集合所包括的至少一个第一资源上发送探测参考信号SRS，第一资源集合为用于天线切换AS的SRS资源集合；第二配置信息用于指示终端在第二资源上发送SRS或上行控制信道PUCCH。然后，若第一资源集合中的第一资源间的至少一个保护间隔GP符号与第二资源中的符号相同，则终端确定在第二资源上发送SRS或PUCCH，避免了第一资源集合所包括的第一资源和第二资源均被闲置的情况，能够提高资源利用效率和信号传输效率。
可选的，该通信方法还可以包括：终端确定在第一资源集合中除满足第一条件的符号之外的第一资源上发送SRS。其中，第一条件为以下条件之一：第一资源集合中位于GP符号前、且与GP符号距离最近的符号；第一资源集合中位于GP符号前、且与GP符号距离最近的第一资源中的所有符号；第一资源集合中位于GP符号后、且与GP符号距离最近的符号；第一资源集合中位于GP符号后、且与GP符号距离最近的第一资源中的所有符号；第一资源集合中位于GP符号前和GP符号后、且与GP符号距离最近的符号；第一资源集合中位于GP符号前和GP符号后、且与GP符号距离最近的第一资源中的所有符号；第一资源集合中与第二资源使用不同发送天线的符号。
可以理解，为了简化处理，终端也可以不进行上述第一条件的判断。因此，可选的，该通信方法还可以包括：终端确定不在第二资源所在时隙内的第一资源集合上发送SRS。
第四方面，提供了一种通信方法，包括：网络设备发送第一配置信息和第二配置信息。其中，第一配置信息用于指示终端在第一资源集合所包括的至少一个第一资源上发送探测参考信号SRS，第一资源集合为用于天线切换AS的SRS资源集合；第二配置信息用于指示终端在第二资源上发送SRS或上行控制信道PUCCH。之后，若第一资源集合中的第一资源间的至少一个保护间隔GP符号与第二资源中的符号相同，则网络设备确定在第二资源上接收SRS或PUCCH，避免了第一资源集合所包括的第一资源和 第二资源均被闲置的情况，能够提高资源利用效率和信号传输效率。
可选的，该通信方法还可以包括：网络设备确定在第一资源集合中除满足第一条件的符号之外的第一资源上接收SRS。其中，第一条件为以下条件之一：第一资源集合中位于GP符号前、且与GP符号距离最近的符号；第一资源集合中位于GP符号前、且与GP符号距离最近的第一资源中的所有符号；第一资源集合中位于GP符号后、且与GP符号距离最近的符号；第一资源集合中位于GP符号后、且与GP符号距离最近的第一资源中的所有符号；第一资源集合中位于GP符号前和GP符号后、且与GP符号距离最近的符号；第一资源集合中位于GP符号前和GP符号后、且与GP符号距离最近的第一资源中的所有符号；第一资源集合中与第二资源使用不同发送天线的符号。
可以理解，为了简化处理，网络设备也可以不进行上述第一条件的判断。因此，可选的，该通信方法还可以包括：网络设备确定不在第二资源所在时隙内的第一资源集合上接收SRS。
可以理解，第一配置信息和第二配置信息是由网络设备确定并发送的，即网络设备也具备第三方面及其可选方案中所述的第一资源与第二资源冲突的判断能力。因此，网络设备可以根据判断结果只在不冲突的资源上接收SRS，以减少网络设备的计算工作量，从而进一步提高SRS的传输效率和上行资源的调度效率。
可以理解，网络设备也可以根据已发送的配置信息，确定待发送的配置信息，以避免两个配置信息所指示的资源冲突。
第五方面，提供了一种通信方法，包括：终端接收第一配置信息和第二配置信息。其中，第一配置信息用于指示终端在第一资源集合所包括的至少一个SRS资源上发送探测参考信号SRS，第一资源集合为用于天线切换AS的SRS资源集合；第二配置信息用于指示终端在第二资源上发送上行控制信道PUCCH。然后，终端在第一资源上发送SRS，在第二资源上发送PUCCH。其中，在同一时隙内，第一资源集合中的第一个第一资源的第一个符号或最后一个第一资源的最后一个符号与第二资源之间存在至少一个保护间隔GP符号。
可选的，若在一个时隙内，所述第二资源的符号位于第一资源集合中所述时隙内的所有SRS资源之前，则终端确定所述第二资源与所述第一资源集合在所述时隙内的第一个SRS资源之间具有Y个符号的GP。
可选的，若在一个时隙内，所述第二资源的符号位于第一资源集合中所述时隙内的所有SRS资源之后，则终端确定所述第二资源与所述第一资源集合在所述时隙内的最后一个SRS资源之间具有Y个符号的GP。其中Y为大于等于1的正整数，可以是网络设备配置的或者预先定义的，例如对于15千赫兹(kilo-hertz，KHz)到60KHz的子载波间隔，Y＝1，对于120KHz子载波间隔Y＝2，对于240KHz子载波间隔Y＝4。所述终端在所述GP内不进行任何传输，或不进行任何上行传输。这样可以在SRS与PUCCH之间如果需要天线切换时可以保证足够的切换时间，从而不影响两者的发送性能。
可以理解的是，第一资源集合中至少一个SRS资源之间的GP符号是否用于传输其他信道或信号，在此不予限定。
第六方面，提供了一种通信方法，包括：网络设备发送第一配置信息和第二配置信息。其中，第一配置信息用于指示终端在第一资源集合所包括的至少一个SRS资源 上发送探测参考信号SRS，第一资源集合为用于天线切换AS的SRS资源集合；第二配置信息用于指示终端在第二资源上发送上行控制信道PUCCH。然后，网络设备在第一资源上接收SRS，在第二资源上接收PUCCH。其中，在同一时隙内，第一资源集合中的第一个第一资源的第一个符号或最后一个第一资源的最后一个符号与第二资源之间存在至少一个保护间隔GP符号。可以理解的是，第一资源集合中至少一个SRS资源之间的GP符号是否用于传输其他信道或信号，在此不予限定。
可以理解，网络设备也可以根据已发送的配置信息，确定待发送的配置信息，以避免两个配置信息所指示的资源冲突。
本申请实施例提供的通信方法，能够在一个时隙内，第一资源集合所包括的一个SRS资源与第二资源之间存在至少一个GP符号的情况下，则在该时隙内，在上述GP符号之前的第一资源上收发SRS，在GP符号之后的第二资源上收发PUCCH，或者在该时隙内，在上述GP符号之后的第一资源上收发SRS，在GP符号之前的第二资源上收发PUCCH，以便为天线切换预留足够时间，从而避免对SRS和PUCCH的传输造成不利影响，能够保证依据SRS测量结果和PUCCH的测量结果评估上行信道质量和调度上行资源的准确性。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：LTE系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，未来的第五代5G系统，如NR系统，以及未来的通信系统，如第六代(6th generation，6G)系统等。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
另外，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例中，“信息(information)”，“信号(signal)”，“消息(message)”，“信道(channel)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例中，有时候下标如W1可能会笔误为非下标的形式如W1，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例既可以应用于时分双工(time division duplexing，TDD)的场景，也可以适用于频分双工(frequency division duplexing，FDD)的场景。
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。以UE为中心的网络引入无小区(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)，每个小站为超级小区的一个传输点(transmission point,TP)或TRP，并与一个集中控制器(controller)相连。当UE在超级小区内移动时，网络侧设备时时为UE选择新的子簇(sub-cluster)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，如基站。
本申请实施例中不同基站可以为具有不同的标识的基站，也可以为具有相同的标识、且被部署在不同地理位置的基站。由于在基站被部署前，基站并不会知道其是否会涉及本申请实施例所应用的场景，因而，基站，或基带芯片，都应在部署前就支持本申请实施例所提供的通信方法。可以理解的是，前述具有不同标识的基站的标识可 以为基站标识，也可以为小区标识或者其他标识。
本申请实施例中部分场景以无线通信网络中NR网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请实施例中，波束beam可以理解为空间资源，可以指具有能量传输指向性的发送或接收预编码向量。并且，该发送或接收预编码向量能够通过索引信息进行标识。其中，所述能量传输指向性可以指在一定空间位置内，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等；所述能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。
可选地，同一通信设备(比如终端或网络设备)可以有不同的预编码向量，不同的设备也可以有不同的预编码向量，即对应不同的波束。
针对通信设备的配置或者能力，一个通信设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个或多个波束。波束的信息可以通过索引信息进行标识。可选地，所述索引信息可以对应配置终端(如用户设备UE)的资源标识(identity，ID)，比如，所述索引信息可以对应配置的信道状态信息参考信号(channel state information reference signal，CSI-RS)的ID或者资源，也可以对应配置的上行探测参考信号(sounding reference signal，SRS)的ID或者资源。或者，可选地，所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息，比如，所述索引信息可以是通过波束发送的同步信号或者广播信道指示该波束的索引信息。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的通信方法的通信系统的示意图。如图1所示，该通信系统100包括网络设备102和终端106，网络设备102可配置有多个天线，终端也可配置有多个天线。可选地，该通信系统还可包括网络设备104，以及提供网络设备104接入网络设备102的终端108，且网络设备104也可配置有多个天线，终端108也可配置有多个天线。
应理解，网络设备102或网络设备104还可包括与信号发送和接收相关的多个部件(例如，处理器、调制器、复用器、解调器或解复用器等)。
其中，网络设备为具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
终端也可以称为用户设备(user equipment，UE)、接入终端、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。本申请的实施例中的终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。本申请中将前述终端及可设置于前述终端的芯片统称为终端。
在该通信系统100中，网络设备102和网络设备104均可以与多个终端(例如图1中示出的终端106和终端110)通信。网络设备102和网络设备104可以与类似于终端106的任意数目的终端通信。但应理解，与网络设备102通信的终端和与网络设备104通信的终端可以是相同的，也可以是不同的。图1中示出的终端106可同时与网络设备102和网络设备104通信，但这仅示出了一种可能的场景，在某些场景中，终端可能仅与网络设备102或网络设备104通信，本申请对此不做限定。
需要说明的是，在采用宏-微基站架构部署的通信系统中，当网络设备为宏基站时，终端也可以替代为微基站或中继站。例如，如图1所示，网络设备102可以为宏基站，相应的，终端可以替代为网络设备104。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备或者还可以包括其他终端，图1中未予以画出。
本申请提供的通信方法涉及各种上行信号，以及用于传输各种上行信号的资源。在LTE中，包括PUSCH、PUCCH和SRS，在5G中，可以对应地针对上行数据信道、控制信道、用于解调的参考信号、用于信道测量的参考信号、随机接入的信道等等。上述资源可以是不同资源粒度的资源，例如可以是最小资源粒度的资源，也可以是一个资源集合。其中，资源集合内包含了一个以上的最小资源粒度。资源集合在时域的角度上可以是系统帧、无线帧、帧、子帧、时隙、半时隙、迷你时隙、符号、符号集合中的至少一个等。在频域的角度上可以是载波、系统带宽、部分带宽、带宽部分、子 带、资源块、子载波、或，服务小区等中的至少一个。资源集合在码域上的角度上可以是上行信号携带的导频序列、伪随机序列、训练序列、正交化码序列、同步序列，或，同步序列的循环移位中的至少一个。资源集合在空域的角度上可以是发射天线、接收天线、波束等中的至少一个。一般地，资源粒度可以是一个信道或信号的调度粒度。举例而言，一个时隙可以包括一个或多个符号，比如包括14个符号，或者，7个符号。一个子帧可以包括一个或多个符号，比如14个符号。
在现代通信系统中，多天线技术被广泛应用，如在LTE、5G NR、WIFI等网络中。一个节点通过多天线发送或者接收信号，后文简称MIMO。在MIMO系统中，节点通过调整MIMO发送、接收方案，如调整发送天线的权值，分配不同的信号到不同的天线上等，可以获取分集、复用等增益，提高系统容量、增加系统可靠性。随着MIMO技术的发展，大规模MIMO(massive MIMO,M-MIMO)的应用，能够进一步提高系统性能。在高频的频段，信号的波长较短，如只有毫米级，对应的天线尺寸也会缩减，这，网络中的节点就有了配置大规模的天线阵列的能力。在M-MIMO中，节点可配置几十个、上百个甚至更多的天线阵子。这些天线阵子，按照一定的排布，如线性排布、圆形排布等，可形成天线阵列。例如，可以将天线阵列划分为多个可独立控制的天线面板，每个天线面板可以包括至少一个天线阵子。其中，可以在上述多个天线面板上同时发射不同波束，也可以在部分天线面板上发射波束,可以通过预编码(precoding)、波束管理(beam management，BM)、天线切换(antenna switching，AS)等中的至少一种技术手段予以实现。节点通过天线阵列发送或者接收信号时，可以通过调整天线阵子上的权值，获得天线增益，使得发送或者接收的信号，在空间中呈现出不均匀的能量分布。通过一些算法，可以使得信号在空间中的部分方向上具有能量集中的效果。这种效果可以成为称为是波束成形。此时信号在空间中形成波束的存在。这里的空间，可以是指水平方向的角度分布和/或垂直方向的角度分布等等。
网络设备和终端之间可以是采用波束传输。波束是一种物理资源，在一些通信系统中，可以是索引为一些导频资源和/或时频资源等等上。
波束的物理含义是，在发送或者接收信号时，可以采用多天线的技术进行发送、接收，传输节点如网络设备、终端等可以对多天线进行权值处理，使得发送和/或接收的信号在一定的空间方向中呈现出能量的非均匀分布，使得信号能量有一定的聚集，这种能量的聚集可以称为是波束。
如图2所示，本申请实施例提供一种通信方法，以适用于NR系统中的SRS传输。本申请实施例可以应用于网络设备与网络设备(如宏基站与微基站)、网络设备与终端之间的通信。在此，以网络设备与终端之间的通信为例进行描述，但并不限于此。
如图2所示，该通信方法200可以包括S201-S206：
S201、网络设备发送第一探测参考信号SRS配置信息和第二SRS配置信息。
其中，第一SRS配置信息用于指示终端在第一SRS资源上发送SRS，第二SRS配置信息用于指示终端在第二SRS资源上发送SRS。
示例性地，网络设备发送第一SRS配置信息和第二SRS配置信息中的任意一个SRS配置信息，可以包括如下步骤：
步骤一：网络设备发送携带有至少一个SRS资源集合的SRS配置信息。
其中，网络设备可以发送携带有至少一个用于上行信道质量探测的信道的资源集合的无线资源控制(radio resource control，RRC)信令。其中，RRC信令可以包括：至少一个用于上行信道质量探测的信道的资源集合、每个用于上行信道质量探测的信道的资源集合的类型(setUse)，以及每个用于上行信道质量探测的信道的资源集合所包括的至少一个用于上行信道质量探测的信道的资源的标识。示例性的，上述用于上行信道质量探测的信道可以为SRS，也可以为物理上行控制信道PUCCH，还可以为其他用于上行信道质量探测的信号、信道、信令等，本申请对此不作限定。
通常，至少一个用于上行信道质量探测的信道的资源集合可以包括：至多1个基于CB的用于上行信道质量探测的信道的资源集合，至多1个基于NCB的用于上行信道质量探测的信道的资源集合，0个、1个或多个用于BM的用于上行信道质量探测的信道的资源集合，以及0个、1个或多个用于AS的用于上行信道质量探测的信道的资源集合。鉴于上述4种类型的用于上行信道质量探测的信道的资源集合为现有技术，此处不再赘述。下文中以SRS和SRS资源集合为例进行说明。
步骤二：网络设备可以采用如下4种方式之一触发SRS资源集合。
方式一：不发送触发指示。
若未接收到触发指示，终端会周期性地在每个SRS资源集合所包括的SRS资源上发送SRS。
与方式一不同，在方式二至方式四中，网络设备还会发送携带有部分或全部SRS资源集合的激活指示或触发指示的信令。具体如下：
方式二：网络设备发送携带有每个SRS资源集合对应的半持续(semi-persistent，SP)激活(avitivation)指示的媒体接入控制控制单元(media access control control element，MAC CE)信令。若上述激活指示表示激活该SRS资源集合，则终端在收到激活指示后，在该SRS资源集合所包括的SRS资源上发送SRS，直到该终端接收到另一个MAC CE信令，且另一个MAC CE信令携带的去激活指示表示去激活该SRS资源集合为止。
需要说明的是，MAC CE信令还可以携带生效时间等信息。其中，生效时间为终端接收到该MAC CE信令后，第一次发送SRS的时间。鉴于生效时间为现有技术，本申请实施例不再赘述。
方式三：网络设备发送携带有SRS资源集合对应的非周期性(aperiodic，AP)触发指示的下行控制信息(downlink control information，DCI)信令。例如，在DCI信令的SRS请求(SRS Request)域可以携带一个或多个SRS资源集合的非周期性触发指示。若上述调度指示表示调度该SRS资源集合，则终端在该SRS资源集合所包括的SRS资源上发送SRS，之后自行停止。
此外，DCI信令还可以携带生效时间、发送次数等信息。其中，生效时间为终端接收到该DCI信令后，第一次发送SRS的时间。发送次数是指，终端接收到一个DCI信令后，终端总共需要发送SRS的次数，在达到发送次数之后，终端自行停止发送SRS。鉴于生效时间、发送次数为现有技术，本申请实施例不再赘述。
方式四：网络设备发送携带有上述非周期性触发指示的DCI信令，此外还需要发送携带有配置所述非周期触发指示所触发的SRS资源集合的候选集合配置信息的MAC  CE信令。
或者，网络设备可以发送携带有上述半持续触发指示的MAC CE信令以及携带有上述非周期触发指示的DCI信令。
示例性的，网络设备可以为同一个SRS资源集合下发在不同时间采用不同发送方式的触发指示，也可以为不同SRS资源集合下发在同一时间采用相同发送方式的触发指示。例如，网络设备为SRS资源集合A下发在第一时间采用半持续方式发送SRS的MAC CE信令，以及在第二时间采用非周期性方式发送SRS的MAC CE信令。又例如，当网络设备要求SRS资源集合A和SRS资源集合B均采用非周期方式发送SRS时，网络设备可以为SRS资源集合A和SRS资源集合B下发同一个携带有非周期触发指示的DCI信令。
需要说明的是，对于采用半持续方式发送SRS的SRS资源集合，网络设备需要为每个SRS资源集合的每次激活各下发一次携带有激活指示的MAC CE信令。而对于采用非周期方式发送SRS的SRS资源集合，网络设备可以在一个DCI信令中携带一个或多于一个SRS资源集合的触发指示。可以理解，对于采用半持续方式发送SRS的SRS资源集合，在终端开始在该SRS资源集合所包括的SRS资源上发送SRS之后，若网络设备需要停止该终端发送SRS，则网络设备还需要下发一个携带有停止发送指示的MAC CE信令。
应理解，第一SRS配置信息和第二SRS配置信息，可以在同一个下行信令中下发，也可以在不同的下行信令中下发。例如，第一SRS配置信息在RRC信令1中下发，第二SRS配置信息在RRC信令2中下发。同理，同一SRS配置信息中的不同部分，可以在同一个下行信令中下发，也可以在不同的下行信令中下发。例如，配置信息中的SRS资源集合，可以在DCI信令中下发，配置信息中的SRS资源集合触发指示，可以在MAC CE信令或DCI信令中下发。
S202、网络设备确定第一SRS资源与第二SRS资源在时间单元内冲突。
其中，时间单元包括：时隙或符号。
示例性的，第一SRS资源与第二SRS资源在时间单元内冲突，可能是由以下至少一个原因导致的：
原因一：受限于终端能力，终端不能在该时间单元内的第一SRS资源上和第二SRS资源上同时发送SRS。例如，终端不支持全天线发送(即终端发送天线数量小于接收天线数量)，若第一SRS资源和第二SRS资源分别位于不同天线上，则第一SRS资源和第二SRS资源冲突。再例如，终端支持BM，若第一SRS资源和第二SRS资源分别对应一个面板上的不同模拟发送波束，则第一SRS资源和第二SRS资源冲突。
原因二：第一SRS资源和第二SRS资源所包括的时域资源，频域资源和码域资源三者均存在相同部分，将会导致在第一SRS资源上发送的SRS与在第二SRS资源上发送的SRS之间存在严重干扰，从而导致网络设备无法正确解析上述两个SRS。
原因三：由于网络设备发送了错误的配置信息，导致第一SRS资源和第二SRS资源在时间单元内冲突。
需要说明的是，实际应用中，还可能存在其他导致冲突的原因，本申请实施例不再赘述。
可选的，当时间单元为符号时，终端还可以确定在所述时间单元所在的时隙内除所述时间单元以外的符号上，不在所述第一SRS资源和第二SRS资源中的一个SRS资源之外的另一个SRS资源上传输SRS，即所述终端确定在所述时间单元所在的时隙内仅在所述第一SRS资源和第二SRS资源中的一个SRS资源上传输SRS，或者说所述终端确定在所述时间单元所在的时隙内，不在所述第一SRS资源和第二SRS资源中的一个SRS资源之外的另一个SRS资源上传输SRS。
或者，所述终端不认为会收到配置了第一SRS资源与第二SRS资源在时间单元内冲突的第一配置信息和第二配置信息。可选的，当终端收到所述配置了第一SRS资源与第二SRS资源在时间单元内冲突的第一配置信息和第二配置信息时，终端确定所述第一配置信息和所述第二配置信息为错误的配置信息。进一步可选的，终端可以在第一SRS资源上发送SRS，也可以在第二SRS资源上发送SRS，还可以不在第一SRS资源和第二SRS资源上发送SRS。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第一时域冲突条件，且第一SRS资源集合和第二SRS资源集合中的至少一个为用于天线切换AS的资源集合。其中，第一时域冲突条件为：第一SRS资源所包括的至少一个时隙与第二SRS资源所包括的至少一个时隙相同，时间单元为时隙。
示例性的，如图3A所示，第一SRS资源集合为用于AS的资源集合，第二SRS资源集合可以是用于AS的资源集合，也可以不是用于AS的资源集合，本申请对此不作限定。下面以第二SRS资源集合不是用于AS的资源集合为例进行说明。
如图3A所示，第一SRS资源集合包括时隙m、时隙m+1和时隙m+2，其中时隙m+1中包含有GP符号，第二SRS资源包括时隙m+1和m+3，不包括时隙m+2(图3A中以虚线框表示)，即第一SRS资源集合和第二SRS资源在时隙m+1上满足第一时域冲突条件。
需要说明的是，图3A中第一SRS资源集合与第二SRS资源只包括一个相同时隙。事实上，相同时隙的数量可以不止一个，且当相同时隙为多个时，多个相同时隙之间可以连续，也可以不连续，本申请对此不作限定。
当然，一个时隙通常可以包括多个符号，一次天线切换通常只需要该时隙中的部分符号。因此，该时隙所包括的不用于天线切换的符号可以用于发送SRS，也可以用于发送其他信号，如下行信道测量报告和数据。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。其中，第一SRS资源集合与第二SRS资源集合可以分别为以下类型的SRS资源集合中的一种：基于码本CB的SRS资源集合、基于非码本NCB的SRS资源集合、用于波束管理BM的SRS资源集合和用于天线切换AS的SRS资源集合。第一SRS资源集合与第二SRS资源集合的类型可以相同，也可以不同。
相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第一类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符 号相同，时间单元为符号。
示例性的，如图3B所示，第一SRS资源包括符号n和n+1，第二SRS资源包括符号n+1和n+2，即第一SRS资源(符号n+1)与第二SRS资源(符号n+1)满足第二时域冲突条件。
需要说明的是，图3B中示出的为一个符号(符号n+1)满足第二时域冲突条件的情形。事实上，满足第二时域冲突条件的符号可能不止一个。当满足第二时域冲突条件的符号为多个时，上述多个符号之间可以连续，也可以不连续，本申请对此不作限定。
可选的，为了简化资源集合类型是否冲突的判断过程，减少计算量，提高判断效率，也可以只判断第一SRS资源集合与第二SRS资源集合是否为同一类型的SRS资源集合。因此，第一类型冲突条件可以为：第一SRS资源集合和第二SRS资源集合为不同类型的SRS资源集合。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第二类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第二类型冲突条件为：第一SRS资源集合与第二SRS资源集合均为用于天线切换AS的SRS资源集合。
在现有NR协议R15中，用于AS的GP符号的位置并不固定。例如，GP符号可以为时隙内所述用于AS的SRS资源集合中SRS资源之间的部分或全部符号，或时隙内所述用于AS的SRS资源集合中SRS资源前和/或后的Y个符号，Y为大于等于0的整数，例如Y＝1或Y＝2。
如图3C所示，第一SRS资源集合包括符号n、符号n+2和符号n+3，符号n+1为GP符号，第二SRS资源集合包括符号n+1和符号n+3，符号n+2为GP符号，即第一SRS资源集合与第二SRS资源集合均包括符号n+3，视为第一SRS资源与第二SRS资源满足第二时域冲突条件和第二类型冲突条件。
需要说明的是，若第一SRS资源集合所包括的第一SRS资源间的GP符号与第二SRS资源集合所包括的第二SRS资源间的GP符号相同，例如上述2个GP符号均为符号n+1，且第一SRS资源与第二SRS资源在其他用于发送SRS的符号上不冲突，则视为第一SRS资源与第二SRS资源不满足第二时域冲突条件和第二类型冲突条件。若第一SRS资源集合所包括的第一SRS资源间的GP符号与第二SRS资源集合所包括的第二SRS资源的SRS符号相同，则可以采用如图5所示的方式进行冲突解决。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第三类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第三类型冲突条件为：第一SRS资源集合为用于波束管理BM的SRS资源集合，第二SRS配置信息中的空间关系信息(spatialRelationInfo，SRI)所指示的第三SRS资源属于第一SRS资源集合，且第三SRS资源与第一SRS资源 不同。
通常，SRI所指示的波束，可以是用来发送SRS的天线面板，即SRS资源也可以包括空域资源。可以理解，第二SRS配置信息中的SRI所指示的第三SRS资源，是指：指示终端在第二SRS资源上，且在与第三SRS资源上发送SRS所使用的天线面板相同的同一天线面板上发送SRS。若第三SRS资源属于第一SRS资源集合，且与第一SRS资源不同，则视为满足第三类型冲突条件。
需要说明的是，本申请并不需要限定第二SRS资源集合是否为用于BM的SRS资源集合类型，即，无论第二SRS资源集合的类型为何种，都可以适用。
可选的，第一SRS资源属于第一SRS资源集合，第二SRS资源属于第二SRS资源集合。相应的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源与第二SRS资源满足第二时域冲突条件和第四类型冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。第四类型冲突条件为：第一SRS配置信息中的空间关系信息所指示的第四SRS资源与第二SRS配置信息中的空间关系信息所指示的第五SRS资源不同，且第四SRS资源与第五SRS资源属于同一个SRS资源集合，且上述同一个SRS资源集合为用于波束管理的SRS资源集合。
示例性的，第一SRS资源集合为基于CB的SRS资源集合，第二SRS资源集合为用于AS的SRS资源集合，第一SRS配置信息中的空间关系信息所指示的第四SRS资源，第二SRS配置信息中的空间关系信息所指示的第五SRS资源，第四SRS资源和第五SRS资源不同，且均属于同一个用于BM的SRS资源集合，视为第一SRS资源和第二SRS资源满足第四类型冲突条件。
需要说明的是，本申请不需要限定第一SRS资源集合与第二SRS资源集合是否为同一类型，即可以为相同类型，也可以为不同类型。其原因在于：只要第一SRS资源的空间关系信息所指示的第四SRS资源和第二SRS资源的空间关系信息所指示的第五SRS资源均属于同一个用于BM的SRS资源集合，且第四SRS资源与第五SRS资源不同，即要求第一SRS资源和第二SRS资源在不同的天线面板上发送SRS，而对于用于BM的SRS资源集合，是不能在同一个天线面板上同时发送不同的SRS的。
可选的，第一SRS资源与第二SRS资源在时间单元内冲突，可以包括：第一SRS资源和第二SRS资源同时满足第二时域冲突条件、频域冲突条件和码域冲突条件。其中，第二时域冲突条件为：第一SRS资源所包括的至少一个符号与第二SRS资源所包括的至少一个符号相同，时间单元为符号。频域冲突条件为：第一SRS资源和第二SRS资源包括至少一个相同子载波；码域冲突条件为：第一SRS资源和第二SRS资源包括至少一个具有相同循环移位的SRS序列。
在不包括S202的情况下，网络设备需要在第一SRS资源和第二SRS资源组成的并集中接收和解析SRS。也就是说，本申请实施例可以不包括S202，即S202为可选步骤。
S203、终端接收第一探测参考信号SRS配置信息和第二SRS配置信息。
示例性的，终端可以通过空口连接接收上述2个SRS配置信息。
S204、终端确定第一SRS资源与第二SRS资源在时间单元内冲突。
示例性的，终端可以采用与S202中相同的通信方法确定第一SRS资源与第二SRS 资源在时间单元内冲突，本申请实施例不再赘述。
可以理解的是，为了确保网络设备和终端判断行为的一致性，以上冲突判断条件可以协议预定义并存储在网络设备和终端中，也可以通过网络设备向终端配置，具体保存方式或配置方式在此不予限定。比如：以上判断条件可以通过网络设备发送第一SRS配置信息或第二SRS配置信息时配置。
S205、终端确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上发送SRS。
可选的，S205终端确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上发送SRS，可以包括：若终端确定第一SRS资源的优先级高于第二SRS资源的优先级，则终端确定在时间单元内，在第一SRS资源上发送SRS，从而能够保证高优先级SRS资源优先用于传输SRS。其中，高优先级SRS资源可以为对上行信道测量和上行资源调度具有更大影响的SRS资源。例如，用于BM的SRS资源，或者在同一时隙内占用符号较多的SRS资源。高优先级SRS资源也可以为对上行信道测量和上行资源调度的时效性要求较高的SRS资源。例如，非周期性(aperiodic，AP)的SRS资源的优先级高于半持续性(semi-persistent，SP)的SRS资源，且半持续性的SRS资源的优先级高于周期性(periodic，P)的SRS资源。此外，高优先级SRS资源还可以为两个SRS资源中调度时间或激活时间在后的SRS资源。
可选的，在终端确定在时间单元内，该通信方法还可以包括：终端接收第三SRS配置信息。其中，第三SRS配置信息用于指示终端在第六SRS资源上发送SRS。然后，终端确定在时间单元内，第六SRS资源与第二SRS资源冲突，且与第一SRS资源不冲突，以及第二SRS资源的优先级高于第六SRS资源的优先级。相应的，终端确定在时间单元内，在第一SRS资源上发送SRS，可以包括：终端在时间单元内，在第一SRS资源上和第六SRS资源上发送SRS。
示例性的，如图4所示，在指定时间段内，如一个时隙(slot)内，第一SRS资源包括符号n、符号n+1和符号n+2，第二SRS资源包括符号n，第六SRS资源包括符号n+2，即第一SRS资源和第六SRS资源均与第二SRS资源冲突，但第一SRS资源与第六SRS资源不冲突。假定第一SRS资源的优先级高于第二SRS资源的优先级，且第二SRS资源的优先级高于第六SRS资源的优先级，则终端可以采用如下两者方式之一确定如何发送SRS。
方式一：终端以发送时间先后顺序判断优先级，并在优先级最高的SRS资源上发送SRS。
步骤一：在符号n上，终端确定第二SRS资源的优先级高于第六SRS资源的优先级，且第二SRS资源与第六SRS资源冲突，终端确定不在第六SRS资源上发送SRS。
步骤二：在符号n+2上，终端确定第一SRS资源的优先级高于第二SRS资源的优先级，且第一SRS资源与第二SRS资源冲突，终端确定不在第二SRS资源上发送SRS，即终端只在第一SRS资源上发送SRS。
方式二：终端在优先级最高的SRS资源上，以及与优先级最高的SRS资源不冲突的SRS资源上发送SRS。
步骤一：终端确定第一SRS资源和第六SRS资源均与第二SRS资源冲突，但第一 SRS资源与第六SRS资源不冲突。
步骤二：终端确定第一SRS资源的优先级高于第二SRS资源的优先级，或者第六SRS资源的优先级高于第二SRS资源的优先级。
步骤三：终端根据步骤一和步骤二的判断结果，确定在第一SRS资源上和第六SRS资源上发送SRS，不在第二SRS资源上发送SRS。
与方式一只在第一SRS资源上发送SRS相比，方式二可以在第一SRS资源上和第六SRS资源上发送SRS，即在保证优先级最高的第一SRS资源优先用于发送SRS的情况下，方式二还能够在第六SRS资源上发送SRS，从而进一步提高了SRS资源的利用效率和SRS的传输效率。
可选的，该通信方法还可以包括：终端上报可在同一个符号内发送SRS的资源数量或端口数量，以便网络设备依据上述资源数量或端口数量为该终端确定SRS配置信息，可以确保配置的资源数量或端口数量不会超过终端所能支持的最大资源数或最大端口数，从而降低不同SRS配置信息所指示的SRS资源冲突的概率，从而进一步提高了SRS资源的利用效率和SRS的传输效率。
S206、网络设备确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上接收SRS。
可以理解，在网络设备确定第一SRS资源与第二SRS资源在时间单元内冲突时，也可以根据终端侧相同的通信方法确定第一SRS资源和第二SRS资源的优先级，并根据确定的优先级确定需要接收和解析的SRS的数量，可以避免在第一SRS资源和第二SRS资源组成的并集上接收和解析SRS的情况，减少了网络设备的计算工作量，从而可以进一步提高SRS的传输效率。基于此，相应的，网络设备确定在时间单元内，在第一SRS资源和第二SRS资源中的一个SRS资源上接收SRS，可以包括：网络设备确定第一SRS资源的优先级高于第二SRS资源的优先级，且在时间单元内，在第一SRS资源上接收SRS。
可选的，该通信方法还包括：网络设备发送第三SRS配置信息。其中，第三SRS配置信息用于指示终端在第六SRS资源上发送SRS。然后，网络设备确定在时间单元内，第六SRS资源与第二SRS资源冲突，且与第一SRS资源不冲突，以及第二SRS资源的优先级高于第六SRS资源的优先级。相应地，网络设备确定在时间单元内，在第一SRS资源上接收SRS，可以包括：网络设备在时间单元内，在第一SRS资源上和第六SRS资源上接收SRS，即在保证优先级最高的第一SRS资源优先用于接收SRS的情况下，网络设备还能够在第六SRS资源上接收SRS，从而进一步提高了SRS资源的利用效率和SRS的传输效率。
可选的，与第一方面所述的终端上报可在同一个符号内发送SRS的资源数量或端口数量相对应，该通信方法还包括：网络设备接收终端可在同一个符号内发送SRS的资源数量或端口数量，并依据上述资源数量或端口数量为该终端确定SRS配置信息，降低不同SRS配置信息所指示的SRS资源冲突的概率，从而进一步提高SRS资源的利用效率和SRS传输效率。
需要说明的是，对于S201-S206，具体的执行顺序可能与其描述顺序可能不同。例如，S202也可以在S201后之执行，也可以在执行S201之前进行，即先判断冲突再 下发SRS配置信息。又例如，S202可以在执行S204之前执行，也可以在执行S204之后执行，只要保证S202在S206之前执行完毕即可。
本申请实施例提供的通信方法，即使第一配置信息所配置的第一SRS资源与第二配置信息所配置的第二SRS资源在时间单元内冲突，也能够在该时间单元内，在第一SRS资源和第二SRS资源中的一个资源上收发SRS，避免了在该时间单元内第一SRS资源和第二SRS资源均被闲置的情况，能够提高SRS资源的利用效率和SRS的传输效率，从而提高了上行信道的测量效率和上行资源的调度效率。
如图5所示，本申请实施例提供一种通信方法，以适用于NR系统中的SRS传输。本申请实施例可以应用于网络设备与网络设备(如宏基站与微基站)，网络设备与终端之间的通信。在此，以网络设备与终端之间的通信为例进行描述，但并不限于此，比如可以统称为发送端与接收端之间的通信。在本申请中，上行可以指终端为发送端，网络设备为接收端，下行可以指网络设备为发送端，终端为接收端。本申请应用于发送端与接收端之间的通信时，上行可以指一个传输方向，下行可以指与上行相对的另一传输方向。

需要说明的是，本申请实施例也可以不包括S502，即S502为可选步骤。在不包括S502的情况下，网络设备需要在第一资源集合和第二资源组成的并集中接收和解析SRS或PUCCH。
需要说明的是，本申请实施例不需要限定第二资源所属的资源集合是否为用于AS的资源集合。若是，则以第二资源作为第一资源集合，将第一资源集合在时隙内所包括的全部资源作为第二资源，然后重新执行本申请实施例提供的通信方法即可。

可选的，为了简化判断过程，降低终端的工作量，终端也可以不再判断第一条件，而是直接确定不在第二资源所在时隙内的第一资源集合上发送SRS，该通信方法还可以包括：终端确定不在第二资源所在时隙内的第一资源集合上发送SRS。
S506、网络设备确定在第二资源上接收SRS或PUCCH。
其中，网络设备可以根据S502中的判断结果，确定终端在第二资源上发送SRS或PUCCH。因此，网络设备也可以有针对性地在第二资源上接收并解析接收到的SRS或PUCCH，可以减少网络设备接收并解析SRS或PUCCH的工作量，从而可以提高信号传输效率。
可选的，网络设备也可以执行上述第一条件中的条件1至条件7中的判断流程(可以理解的是，网络设备和终端应遵循相同的条件)，并根据判断结果确定在与终端发 送SRS相同的第一资源上接收SRS，以便网络设备有正对性地接收和解析SRS，减少工作量，从而提高SRS的传输效率和上行资源调度效率。

其中，第一配置信息用于指示终端在第一资源集合所包括的至少一个第一资源上发送探测参考信号SRS，第一资源集合为用于天线切换AS的SRS资源集合；第二配置信息用于指示终端在第二资源上发送上行控制信道PUCCH。

具体的，若在一个时隙内，所述第二资源的符号位于第一资源集合中所述时隙内的所有SRS资源之前，终端确定所述第二资源与所述第一资源集合在所述时隙内的第一个SRS资源之间具有Y个符号的GP；若在一个时隙内，所述第二资源的符号位于第一资源集合中所述时隙内的所有SRS资源之后，则终端确定所述第二资源与所述第一资源集合在所述时隙内的最后一个SRS资源之间具有Y个符号的GP。其中Y为大于等于1的正整数，可以是基站配置的或者预先定义的，例如对于15KHz到60KHz的子载波间隔，Y＝1，对于120KHz子载波间隔Y＝2，对于240KHz子载波间隔Y＝4.所述终端在所述GP内不进行任何传输，或不进行任何上行传输。这样可以在SRS与PUCCH之间如果需要天线切换时可以保证足够的切换时间，从而不影响两者的发送性能。
