Description

探测参考信号的传输方法、装置及系统
本申请要求于2017年08月11日提交中国专利局、申请号为201710687907.3、申请名称为“探测参考信号的传输方法、装置及系统”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，尤其涉及探测参考信号(sounding reference signal，SRS)的传输方法、装置及系统。
背景技术
为了进行上行信道测量，长期演进(long term evolution，LTE)系统引入了SRS。同时，在时分双工(time division multiplexing，TDD)场景下，利用上下行信道的互易性，根据SRS测量的上行信道信息还可以进行准确的下行传输。
现有技术中，LTE-版本(release)13最多支持32成员载波(component carrier，CC)的载波聚合(carrier aggregation，CA)。并且，受限于终端的能力，配置的上行CC数通常不能大于下行CC数。这样，当配置有TDDCC时，若一些TDD CC仅用于下行传输，则终端无法在这些TDD CC上传输SRS，进而无法根据SRS测量的上行信道信息进行准确的下行传输。为了解决该问题，LTE-release14引入了SRS的载波级切换(SRS carrier-based switching)，即可以从一个CC切换到另一个CC上传输SRS，从而可以测量另一个CC的上行信道信息。其中，切换前的CC记作switching from CC，切换后的CC记作switching to CC。switching from CC为上行可以传输物理上行共享信道(physical uplink shared channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理随机接入信道(physical random access channel，PRACH)或SRS中至少一个的载波，switching to CC为上行仅传输SRS和/或PRACH的TDD载波。
类似的，在新空口(new radio，NR)支持的宽带CC中，可以将宽带CC划分为多个带宽部分(bandwidth Part，BP或BWP，以下均用BP表示)。其中，对于上行可以传输PUSCH、PUCCH、PRACH或SRS等的BP称为上行(uplink，UL)BP；对于上行仅传输SRS和/或PRACH的带宽部分(bandwidth Part，BP或BWP，以下均用BP表示)称为SRS BP。另外，由于NR设计时，终端的射频(Radio Frequency，RF)能力和系统带宽解耦，终端的RF能力和终端的工作带宽解耦，因此可能出现多个SRS BP。为了测量SRS BP的上行信道信息，终端可以从终端激活的上行BP切换到SRS BP。此时，如何进行SRS的BP级切换(SRS BP-based switching)，目前并没有相关的解决方案。
发明内容
本申请实施例提供SRS的传输方法、设备及系统，可以实现SRS的BP级切换。
为达到上述目的，本申请实施例提供如下技术方案：
第一方面，提供一种探测参考信号SRS的传输方法，该方法包括：确定第一带宽部分BP上的SRS与第二BP上的SRS发生传输冲突；丢弃该第一BP上的SRS，其中，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级。基于该方案，由于在两个BP上的SRS发生传输冲突的情况下，可以丢弃SRS的优先级较低的SRS，也就是说，可以使得终端从激活的上行BP切换到传输优先级较高的SRS的BP上，在传输优先级较高的SRS的BP上传输SRS，因此可以实现SRS的BP级切换。
可选的，该第一BP为终端激活的上行BP，该第二BP为该终端的SRSBP；或者，该第一BP和该第二BP均为该终端的SRSBP。其中，若第一BP为终端激活的上行BP，该第二BP为该终端的SRSBP，则终端可以从第一BP切换到第二BP，在第二BP上传输SRS；若第一BP和第二BP均为该终端的SRSBP，则终端可以从激活的上行BP切换切换到第二BP，在第二BP上传输SRS。
可选的，该第一BP上的SRS的优先级和该第二BP上的SRS的优先级与终端的射频RF位置相关。
比如，在一种可能的设计中，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级，包括：该第一BP为终端的RF内的SRSBP，该第二BP为该终端的RF外的SRSBP。也就是说，考虑到终端激活的上行BP在终端的RF内，因此，终端从激活的上行BP切换到第一BP时不需要进行RF切换，终端从激活的上行BP切换到第二BP时需要进行RF切换。而通常在不需要进行RF切换的SRS BP上，SRS配置的密度较高；在需要进行RF切换的SRS BP上，SRS配置的密度较低，因此，为了尽快的获取整个载波带宽的信道状态，可以在终端的RF外的SRSBP上的SRS和终端的RF内的SRSBP上的SRS发生传输冲突时，丢弃终端的RF内的SRSBP。
或者，比如，在一种可能的设计中，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级，包括：该第一BP和该第二BP均为终端的RF内的SRSBP，且该第一BP上的SRS的传输周期小于该第二BP上的SRS的传输周期，其中，该第一BP上的SRS和该第二BP上的SRS均是周期性SRS，或者，该第一BP上的SRS和该第二BP上的SRS均是半静态SRS。也就是说，对于与终端的RF的相对位置相同的BP上的同类型SRS，考虑到传输周期较小的SRS相对于传输周期较大的SRS出现的概率更高，因此可以在传输周期较小的SRS和传输周期较大的SRS发生传输冲突时，丢弃传输周期较小的SRS，等下一个传输周期再传输该SRS。
或者，比如，在一种可能的设计中，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级，包括：该第一BP和该第二BP均为终端的RF外的SRSBP，且该第一BP上的SRS的传输周期小于该第二BP上的SRS的传输周期，其中，该第一BP上的SRS和该第二BP上的SRS均是周期性SRS，或者，该第一BP上的SRS和该第二BP上的SRS均是半静态SRS。也就是说，对于与终端的RF的相对位置相同的BP上的同类型SRS，考虑到传输周期较小的SRS相对于传输周期较大的SRS出现的概率更高，因此可以在传输周期较小的SRS和传输周期较大的SRS发生传输冲突时，丢弃传输周期较小的SRS，等下一个传输周期再传输该SRS。
或者，比如，在一种可能的设计中，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级，包括：该第一BP和该第二BP均为终端的RF内的SRSBP，且 该第一BP上的SRS为周期性SRS，该第二BP上的SRS为半静态SRS；或者，该第一BP上的SRS为周期性SRS，该第二BP上的SRS为非周期性SRS；或者，该第一BP上的SRS为半静态SRS，该第二BP上的SRS为非周期性SRS。也就是说，对于不同类型的SRS，考虑到非周期性SRS出现较为不规律，半静态SRS虽然出现较为规律，但是取决于DCI触发还是终止，周期性SRS出现规律，且不依赖外部条件，因此可以在周期性SRS与半静态SRS发生传输冲突时，丢弃周期性SRS，等下次出现再传输该SRS；在非周期性SRS与半静态SRS发生传输冲突时，丢弃半静态SRS，等下次出现再传输该SRS。即，非周期性SRS的优先级＞半静态SRS的优先级＞周期性SRS的优先级。
或者，比如，在一种可能的设计中，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级，包括：该第一BP和该第二BP均为终端的RF外的SRSBP，且该第一BP上的SRS为周期性SRS，该第二BP上的SRS为半静态SRS；或者，该第一BP上的SRS为周期性SRS，该第二BP上的SRS为非周期性SRS；或者，该第一BP上的SRS为半静态SRS，该第二BP上的SRS为非周期性SRS。也就是说，对于不同类型的SRS，考虑到非周期性SRS出现较为不规律，半静态SRS虽然出现较为规律，但是取决于DCI触发还是终止，周期性SRS出现规律，且不依赖外部条件，因此可以在周期性SRS与半静态SRS发生传输冲突时，丢弃周期性SRS，等下次出现再传输该SRS；在非周期性SRS与半静态SRS发生传输冲突时，丢弃半静态SRS，等下次出现再传输该SRS。即，非周期性SRS的优先级＞半静态SRS的优先级＞周期性SRS的优先级。
可选的，该第一BP上的SRS的优先级低于该第二BP上的SRS的优先级，包括：该第一BP上的SRS的传输周期小于该第二BP上的SRS的传输周期，其中，该第一BP上的SRS和该第二BP上的SRS均是周期性SRS，或者，该第一BP上的SRS和该第二BP上的SRS均是半静态SRS。也就是说，对于同类型的SRS，考虑到传输周期较小的SRS相对于传输周期较大的SRS出现的概率更高，因此可以在传输周期较小的SRS和传输周期较大的SRS发生传输冲突时，丢弃传输周期较小的SRS，等下一个传输周期再传输该SRS。
可选的，该第一BP和该第二BP为同一个宽带成员载波CC中的BP。
可选的，该方法还包括：接收SRS的配置信息，其中，该SRS的配置信息包括该第一BP上的SRS的配置信息和该第二BP上的SRS的配置信息，该第一BP上的SRS的配置信息包括在该第一BP上传输SRS的第一时域资源，该第二BP上的SRS的配置信息包括在该第二BP上传输SRS的第二时域资源；该确定第一BP上的SRS与第二BP上的SRS发生传输冲突，包括：根据该第一时域资源、该第二时域资源和RF切换时间，确定该第一BP上的SRS与该第二BP上的SRS发生传输冲突。基于该方式，可以确定第一BP上的SRS与第二BP上的SRS发生传输冲突。
在一种可能的设计中，该根据该第一时域资源、该第二时域资源和RF切换的时间，确定该第一BP上的SRS与该第二BP上的SRS发生传输冲突，包括：根据该第一时域资源、该第二时域资源、第一RF切换时间和第二RF切换时间，确定该终端从该终端激活的上行BP切换到该第一BP上时所需的时域资源和该终端从该终端激活的 上行BP切换到该第二BP上时所需的时域资源存在重叠部分，其中，该第一RF切换时间为该终端从该终端激活的上行BP切换到该第一BP上时所需的时间，该第二RF切换时间为该终端从该终端激活的上行BP切换到该第二BP上时所需的时间，该第一BP和该第二BP均为该终端的SRSBP。基于该方式，可以确定第一BP上的SRS与第二BP上的SRS发生传输冲突。
在一种可能的设计中，该根据该第一时域资源、该第二时域资源和RF切换的时间，确定该第一BP上的SRS与该第二BP上的SRS发生传输冲突，包括：根据该第一时域资源、该第二时域资源和第三RF切换时间，确定该终端从该第一BP切换到该第二BP时所需的时域资源包括该第二时域资源，其中，该第三RF切换时间为该终端从该第一BP切换到该第二BP上时所需的时间，该第一BP为该终端激活的上行BP，该第二BP为该终端的SRSBP。基于该方式，可以确定第一BP上的SRS与第二BP上的SRS发生传输冲突。
第二方面，提供了一种通信装置，该SRS的传输装置具有实现上述第一方面所述的方法的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块。
第三方面，提供了一种通信装置，包括：处理器和存储器；该存储器用于存储计算机执行指令，该处理器与该存储器连接，当该SRS的传输装置运行时，该处理器执行该存储器存储的计算机执行指令，以使该SRS的传输装置执行如上述第一方面中任一所述的SRS的传输方法。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术的简要介绍如下。
TDD:TDD模式是指系统中的接收和传送是在同一频率信道即载波的不同时隙，用保证时间来分离接收与传送信道。
频分双工(frequencydivision duplexing，FDD)：FDD模式是指系统中的接收和传送是在分离的两个对称频率信道上，用保证频段来分离接收与传送信道。
周期性SRS(periodic SRS，P-SRS)：无线资源控制(radio resource control，RRC)信令配置SRS传输使用的时域、频域、码域和梳齿(comb)资源。其中，时域资源包括：SRS的周期、SRS发送的时隙(slot)和SRS发送使用的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。按照配置的SRS的周期，每隔SRS的周期发送一次SRS。
非周期性SRS(aperiodic SRS，A-SRS)：RRC信令配置SRS传输使用的时域、频域、码域和comb资源。其中，SRS传输使用的时域资源是不固定的，由下行控制信息(downlink control information，DCI)触发终端不定期的发送SRS。
半静态SRS(semi-persistent scheduling SRS，SPS-SRS)：RRC信令配置SRS传输使用的时域、频域、码域和comb资源。其中，时域资源包括：SRS的周期、SRS发送的slot和SRS发送使用的OFDM符号。DCI触发终端按照配置的SRS的周期，每隔SRS的周期发送一次SRS。此外，DCI还可以触发终端终止SRS的发送。
载波：本申请实施例中的载波包括非CA场景下的载波和CA场景下的CC。其中，CA场景下的CC可以为主CC或辅CC，CA场景下的服务小区可以为主服务小区(primary serving cell，PCell)或辅服务小区(secondary serving cell，Scell)。为了方便描述，在本申请实施例的某些场景下，可以将非CA场景下的载波和CA场景下的CC统称为载波，本申请实施例对此不作具体限定。此外，载波或服务小区用于上行传输的部分可以理解为上行资源或上行载波，载波或服务小区用于下行传输的部分可以理解为下行资源或下行载波。例如，在FDD系统中，载波上用于上行传输的频域资源可以理解为上行资源或上行载波；载波上用于下行传输的频域资源可以理解为下行资源或下行载波。或者，例如，在TDD系统中，载波上用于上行传输的时域资源可以理解为上行资源或上行载波；载波上用于下行传输的时域资源可以理解为下行资源或下行载波。
工作带宽：即终端激活的(active)BP。其中，工作带宽分包括上行工作带宽和下行工作带宽。上行工作带宽即终端激活的上行BP，下行工作带宽即终端激活的下行BP，在此进行统一说明，以下不再赘述。
子带或BP：即载波上的一段频域资源。
UL BP：指上行可以传输PUSCH、PUCCH或SRS等的BP，该BP具有带宽大小、带宽位置和带宽的子载波间隔等属性。
SRS BP：指上行仅传输SRS和/或PRACH的BP，该BP具有带宽大小、带宽位 置和带宽的子载波间隔等属性。
RF切换(retuning)：本申请实施例中的RF切换发生在不在同一个RF覆盖范围内的两个BP之间。若发生切换的两个BP在同一个RF的覆盖范围内，则不会发生RF切换。其中，本申请实施例中，两个BP在同一个RF的覆盖范围内是指，这两个BP的全部频域资源均在同一个RF的覆盖范围；两个BP不在同一个RF的覆盖范围内是指，这两个BP的全部频域资源不在同一个RF的覆盖范围，在此进行统一说明，以下不再赘述。
比如，如图1中(1a)所示，若终端从激活的上行BP切换到SRS BP1或SRS BP2，则由于激活的上行BP、SRS BP1和SRS BP2均在的RF的覆盖范围内，此时不会发生RF切换；若终端从激活的上行BP切换到SRS BP3，则由于激活的上行BP在的RF的覆盖范围内，SRS BP3在的RF的覆盖范围外，即两个BP不在同一个RF的覆盖范围内，因此将发生RF切换。如图1中(1b)所示，发生RF切换后RF覆盖SRS BP3，此时可以在SRS BP3上发送SRS。
或者，如图2的(2a)所示，若终端从激活的上行BP切换到SRS BP1，则由于激活的上行BP和SRS BP1均在的RF的覆盖范围内，此时不会发生RF切换；若终端从激活的上行BP切换到SRS BP3，则由于激活的上行BP在的RF的覆盖范围内，SRS BP3在的RF的覆盖范围外，即两个BP不在同一个RF的覆盖范围内，因此将发生RF切换。如图2的(2b)所示，发生RF切换后RF覆盖SRS BP3，此时可以在SRS BP3上发送SRS；若终端从激活的上行BP切换到SRS BP2，则由于激活的上行BP在的RF的覆盖范围内，SRS BP2的一部分在的RF的覆盖范围内，一部分在的RF的覆盖范围外，此时两个BP也认为不在同一个RF的覆盖范围内，因此将发生RF切换。如图2的(2c)所示，发生RF切换后RF覆盖SRS BP2，此时可以在SRS BP2上发送SRS。
需要说明的是，图2所示的示例中，发生RF切换后，RF的中心与SRS BP2或SRS BP3的中心并未对齐，当然，也可以采用RF的中心与SRS BP的中心对齐的方式进行RF切换，本申请实施例对此不作具体限定，附图仅用于示例性说明RF切换的场景。

如图5所示，为本申请实施例提供的一种SRS的传输方法的流程示意图。该SRS的传输方法中，若终端确定第一BP上的SRS与第二BP上的SRS发生传输冲突，则丢弃SRS的优先级较低的BP上的SRS，从而可以实现SRS的BP级切换。具体的，该SRS的传输方法包括如下步骤：
S501、基站向终端发送SRS的配置的信息。
其中，本申请实施例中，SRS的配置信息包括第一BP上的SRS的配置信息和第二BP上的SRS的配置信息。该第一BP上的SRS的配置信息包括在第一BP上传输SRS的第一时域资源，该第二BP上的SRS的配置信息包括在第二BP上传输SRS的第二时域资源。
具体的，本申请实施例中的第一时域资源用于在第一BP上传输SRS，第二时域资源用于在第二BP上传输SRS。其中，这里的时域资源包括时隙内用于SRS传输的OFDM符号的个数和位置等信息，在此进行统一说明，以下不再赘述。
可选的，本申请实施例中，基站可以将SRS的配置信息携带在RRC信令中发送给终端，本申请实施例对此不作具体限定。
可选的，本申请实施例中的第一BP和第二BP可以是根据终端激活的上行BP和终端的RF中的至少一个确定的，本申请实施例对此不作具体限定。
可选的，本申请实施例中的第一BP和第二BP可以是CA场景下同一个CC载波中的BP，或者是非CA场景下载波中的BP。比如，如图1或图2所示，第一BP可以是SRS BP1，第二BP可以是SRS BP2；或者，第一BP可以是SRS BP2，第二BP可以是SRS BP3；或者，第一BP可以是SRS BP1，第二BP可以是SRS BP3。

可选的，本申请实施例中CC载波可以是宽带CC载波，也可以是非宽带CC载波，本申请实施例对此不作具体限定。
需要说明的是，为了方便描述，下述实施例均以第一BP和第二BP是CA场景下同一个宽带CC载波中的BP为例进行说明，在此进行统一说明，以下不再赘述。

S502、终端接收来自基站的SRS的配置信息。
S503、终端根据第一时域资源、第二时域资源和RF切换时间，确定第一BP上的SRS和第二BP上的SRS发生传输冲突。
可选的，本申请实施例中的RF切换时间是指，在发生RF切换时，终端从一个BP切换到另外一个BP上时所需的时间。比如，如图6的(6a)所示，假设当终端从子载波间隔为30kHZ的BP1切换到子载波间隔为30kHZ的BP2时发生RF切换，则RF切换时间＝t1，即时隙N的OFDM符号9，10，11，12所对应的时间。假设SRS在时隙N的OFDM符号13上传输，则RF切换的往返时间＝2×t1+SRS的传输时间，即时隙N的OFDM符号9，10，11，12，13对应的时间以及时隙N+1的OFDM符号0，1，2，3对应的时间。
可选的，本申请实施例中的RF切换时间与终端的RF能力相关，通常，终端的RF能力越强，RF切换时间越短。此外，RF切换时间可以配置在终端中或者由终端根据终端的RF能力确定，具体可参考现有的实现方式，本申请实施例对此不作具体限定。
可选的，本申请实施例中，终端也可以将RF切换时间上报给基站，以使得基站可以根据RF切换时间下发相应的时域资源，具体可参考协议3GPP TS36.331中UE能力中关于RF切换时间的描述，在此不再赘述。
可选的，本申请实施例中，第一BP上的SRS和第二BP上的SRS发生传输冲突包括以下两种场景：
场景一，第一BP为终端激活的上行BP，第二BP为终端的SRS BP，即存在一个BP对，该BP对由第一BP和第二BP组成：
此时，步骤S503具体可以包括：终端根据第一时域资源、第二时域资源和第三RF切换时间，确定终端从第一BP切换到第二BP时所需的时域资源包括第二时域资 源，其中，第三RF切换时间为终端从第一BP切换到第二BP上时所需的时间。
示例性的，如图6的(6a)所示，假设第一BP为子载波间隔为30kHZ的BP1，第二BP为子载波间隔为30kHZ的BP2，第一时域资源为时隙N的OFDM符号13，即第一BP上的SRS在时隙N的OFDM符号13上传输；第二时域资源为时隙N的OFDM符号13，即第二BP上的SRS在时隙N的OFDM符号13上传输；第三RF切换时间为4个OFDM符号。则，根据第一时域资源、第二时域资源和第三RF切换时间可知，从BP1切换到BP2所需的时域资源为时隙N的OFDM符号9，10，11，12，13以及时隙N+1的OFDM符号0，1，2，3，包括时隙N的OFDM符号13，即与第二时域资源存在重合部分。也就是说，若在BP1上传输SRS，则无法在BP2上传输SRS；若在BP2上传输SRS，则无法在BP1上传输SRS。即，BP1上的SRS传输所需的时域资源和BP2上的SRS传输所需的时域资源发生冲突。
场景二，第一BP为SRS BP，第二BP为SRS BP，即存在两个BP对，其中一个BP对由终端激活的上行BP和第一BP组成，另外一个BP对由终端激活的上行BP和第二BP组成：
此时，步骤S503具体可以包括：终端根据第一时域资源、第二时域资源、第一RF切换时间和第二RF切换时间，确定终端从终端激活的上行BP切换到第一BP上时所需的时域资源和终端从终端激活的上行BP切换到第二BP上时所需的时域资源存在重叠部分，其中，第一RF切换时间为终端从终端激活的上行BP切换到第一BP上时所需的时间，第二RF切换时间为终端从终端激活的上行BP切换到第二BP上时所需的时间。
示例性的，如图6的(6a)和(6b)所示，假设终端激活的上行BP为子载波间隔为30kHZ的BP1，第一BP为子载波间隔为30kHZ的BP2，第二BP为子载波间隔为60kHZ的BP3，第一BP对应的第一时域资源为时隙N的OFDM符号13，即第一BP上的SRS在时隙N的OFDM符号13上传输；第二BP对应的第二时域资源为时隙N的OFDM符号13，即第二BP上的SRS在时隙N的OFDM符号13上传输；第一RF切换时间和第二RF切换时间均为4个OFDM符号。则，根据第一时域资源和第一RF切换时间可知，从BP1切换到BP2所需的时域资源为时隙N的OFDM符号9，10，11，12，13以及时隙N+1的OFDM符号0，1，2，3；根据第二时域资源和第二RF切换时间可知，从BP1切换到BP3所需的时域资源为时隙N的OFDM符号2至OFDM符号10。此时，终端从BP1切换到BP2上时所需的时域资源和终端从BP1切换到BP3上时所需的时域资源存在重叠部分，重叠部分为时隙N的OFDM符号9和10。因此，若终端从BP1切换到BP2，则无法从BP1切换到BP3；若终端从BP1切换到BP3，则无法从BP1切换到BP2，也就是说，若在BP2上传输SRS，则无法在BP3上传输SRS；若在BP3上传输SRS，则无法在BP2上传输SRS。即，BP2上的SRS传输所需的时域资源和BP3上的SRS传输所需的时域资源发生冲突。
需要说明的是，步骤S501至S503仅是示例性的给出了一种确定第一BP上的SRS和第二BP上的SRS发生传输冲突的具体实现。当然，还可能存在其他确定第一BP上的SRS和第二BP上的SRS发生传输冲突的方式。本申请实施例是为了解决在BP之间的SRS发生冲突后进行SRS传输的问题，只要确定出第一BP上的SRS和第二 BP上的SRS发生传输冲突，都可以采用本申请实施例的方案，因此本申请实施例对如何确定两个BP上的SRS发生传输冲突不作具体限定。
S504、终端丢弃第一BP上的SRS。
其中，第一BP的上的SRS的优先级低于第二BP上的SRS的优先级。也就是说，终端丢弃SRS的优先级较低的BP上的SRS。
可选的，本申请实施例中，在第一BP上的SRS和第二BP上的SRS发生传输冲突时：
若第一BP为终端激活的上行BP，第二BP为SRS BP，则终端丢弃第一BP上的SRS具体是指，终端可以从第一BP切换到第二BP，在第二BP上传输SRS。
若第一BP和第二BP均为SRS BP，则终端丢弃第一BP上的SRS具体是指，终端可以从终端激活的上行BP切换到第二BP，在第二BP上传输SRS。
可选的，本申请实施例中可以通过如下方式确定第一BP的上的SRS的优先级低于第二BP上的SRS的优先级：
方式一：通过SRS的传输周期确定不同BP上的SRS的优先级。具体的，第一BP上的SRS的优先级低于第二BP上的SRS的优先级，包括：第一BP上的SRS的传输周期小于所述第二BP上的SRS的传输周期，其中，第一BP上的SRS和第二BP上的SRS均是周期性SRS；或者，第一BP上的SRS和第二BP上的SRS均是半静态SRS。也就是说，对于同类型的SRS，考虑到传输周期较小的SRS相对于传输周期较大的SRS出现的概率更高，因此可以在传输周期较小的SRS和传输周期较大的SRS发生传输冲突时，丢弃传输周期较小的SRS，等下一个传输周期再传输该SRS。其中，周期性SRS和半静态SRS的相关描述可参考具体实施方式部分的前序部分，在此不再赘述。
示例性的，假设第一BP为图2的(2a)中的SRS BP1，第二BP为图2的(2a)中的SRS BP3。SRS BP1为周期性SRS，传输周期为T1；SRS BP3为周期性SRS，传输周期为T2，其中，T1＜T2，则由于传输周期较小的SRS的优先级低于传输周期较大的SRS的优先级，因此在SRS BP1上的SRS和SRS BP3上的SRS发生传输冲突时，终端将丢弃SRS BP1上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP3，在SRS BP3上传输SRS。
方式二：通过不同BP与终端的RF的相对位置确定不同BP上的SRS的优先级。具体的，第一BP上的SRS的优先级低于第二BP上的SRS的优先级，包括：第一BP为终端的RF内的SRSBP，第二BP为终端的RF外的SRSBP。也就是说，考虑到终端激活的上行BP在终端的RF内，因此，终端从激活的上行BP切换到第一BP时不需要进行RF切换，终端从激活的上行BP切换到第二BP时需要进行RF切换。而通常在不需要进行RF切换的SRS BP上，SRS配置的密度较高；在需要进行RF切换的SRS BP上，SRS配置的密度较低，因此，为了尽快的获取整个载波带宽的信道状态，可以在终端的RF外的SRSBP上的SRS和终端的RF内的SRSBP上的SRS发生传输冲突时，丢弃终端的RF内的SRSBP。
示例性的，假设第一BP为图2的(2a)中的SRS BP1，第二BP为图2的(2a)中的SRS BP2。则由于SRS BP1在终端的RF内，SRS BP2在终端的RF外，因此在 SRS BP1上的SRS和SRS BP2上的SRS发生传输冲突时，终端将丢弃SRS BP1上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP2，在SRS BP2上传输SRS。
方式三：通过BP的类型确定不同BP上的SRS的优先级。具体的，第一BP上的SRS的优先级低于第二BP上的SRS的优先级，包括：第一BP为终端激活的上行BP，第二BP为终端的SRSBP。也就是说，考虑到终端激活的上行BP上SRS配置的密度相对终端的SRSBP上SRS配置的密度较高，因此，为了尽快的获取整个载波带宽的信道状态，可以在终端激活的上行BP上的SRS和终端的SRS BP上的SRS发生传输冲突时，丢弃终端激活的上行BP上的SRS。
示例性的，假设第一BP为图2的(2a)中的激活的上行BP，第二BP为图2的(2a)中的SRS BP2。则由于激活的上行BP的优先级低于SRS BP的优先级，因此在激活的上行BP上的SRS和SRS BP2上的SRS发生传输冲突时，终端将丢弃激活的上行BP上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP2，在SRS BP2上传输SRS。
方式四：通过SRS的传输周期以及BP与终端的RF的相对位置确定不同BP上的SRS的优先级。具体的，第一BP上的SRS的优先级低于第二BP上的SRS的优先级，包括：第一BP和第二BP均为终端的RF内的SRSBP或者均为终端的RF外的SRSBP，且第一BP上的SRS的传输周期小于第二BP上的SRS的传输周期，其中，第一BP上的SRS和第二BP上的SRS均是周期性SRS；或者，第一BP上的SRS和第二BP上的SRS均是半静态SRS。也就是说，对于与终端的RF的相对位置相同的BP上的同类型SRS，考虑到传输周期较小的SRS相对于传输周期较大的SRS出现的概率更高，因此可以在传输周期较小的SRS和传输周期较大的SRS发生传输冲突时，丢弃传输周期较小的SRS，等下一个传输周期再传输该SRS。其中，周期性SRS和半静态SRS的相关描述可参考具体实施方式部分的前序部分，在此不再赘述。
与方式一的区别在于，方式一中不考虑不同BP与终端的RF的相对位置，仅考虑SRS的传输周期；而方式四中，第一BP和第二BP均为终端的RF内的SRSBP，或者，第一BP和第二BP均为终端的RF外的SRSBP。
示例性的，假设第一BP为图1的(1a)中的SRS BP1，第二BP为图1的(1a)中的SRS BP2。SRS BP1为半静态SRS，传输周期为T3；SRS BP2为半静态SRS，传输周期为T4，其中，T3＜T4，则由于由于传输周期较小的SRS的优先级低于传输周期较大的SRS的优先级，因此在SRS BP1上的SRS和SRS BP2上的SRS发生传输冲突时，终端将丢弃SRS BP1上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP2，在SRS BP2上传输SRS。
或者，示例性的，假设第一BP为图2的(2a)中的SRS BP2，第二BP为图2的(2a)中的SRS BP3。SRS BP2为周期性SRS，传输周期为T5；SRS BP3为周期性SRS，传输周期为T2，其中，T5＜T2，则由于传输周期较小的SRS的优先级低于传输周期较大的SRS的优先级，因此在SRS BP2上的SRS和SRS BP3上的SRS发生传输冲突时，终端将丢弃SRS BP2上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP3，在SRS BP3上传输SRS。
方式五：通过SRS的类型以及BP与终端的RF的相对位置确定不同BP上的SRS 的优先级。具体的，第一BP上的SRS的优先级低于第二BP上的SRS的优先级，包括：第一BP和所述第二BP均为终端的RF内的SRSBP或者均为终端的RF外的SRS BP，且所述第一BP上的SRS为周期性SRS，所述第二BP上的SRS为半静态SRS；或者，所述第一BP上的SRS为周期性SRS，所述第二BP上的SRS为非周期性SRS；或者，所述第一BP上的SRS为半静态SRS，所述第二BP上的SRS为非周期性SRS。也就是说，对于不同类型的SRS，考虑到非周期性SRS出现较为不规律，半静态SRS虽然出现较为规律，但是取决于DCI触发还是终止，周期性SRS出现规律，且不依赖外部条件，因此可以在周期性SRS与半静态SRS发生传输冲突时，丢弃周期性SRS，等下次出现再传输该SRS；在非周期性SRS与半静态SRS发生传输冲突时，丢弃半静态SRS，等下次出现再传输该SRS。即，非周期性SRS的优先级＞半静态SRS的优先级＞周期性SRS的优先级。其中，周期性SRS、非周期性SRS和半静态SRS的相关描述可参考具体实施方式部分的前序部分，在此不再赘述。
示例性的，假设第一BP为图1的(1a)中的SRS BP1，第二BP为图1的(1a)中的SRS BP2。SRS BP1为半静态SRS；SRS BP2为非周期性SRS，则由于半静态SRS的优先级低于非周期性SRS的优先级，因此在SRS BP1上的SRS和SRS BP2上的SRS发生传输冲突时，终端将丢弃SRS BP1上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP2，在SRS BP2上传输SRS。
或者，示例性的，假设第一BP为图2的(2a)中的SRS BP2，第二BP为图2的(2a)中的SRS BP3。SRS BP2为周期性SRS；SRS BP3为非周期性SRS，则由于周期性SRS的优先级低于非周期性SRS的优先级，因此在SRS BP2上的SRS和SRS BP3上的SRS发生传输冲突时，终端将丢弃SRS BP2上的SRS。比如，终端可以从终端激活的上行BP切换到SRS BP3，在SRS BP3上传输SRS。
上述示例一至示例五中提供了几种确定第一BP的上的SRS的优先级低于第二BP上的SRS的优先级的方式，其中，在示例二、示例四和示例五中，第一BP上SRS的优先级和第二BP上的SRS的优先级与终端的RF位置相关。当然，还可以通过其它方式确定第一BP的上的SRS的优先级低于第二BP上的SRS的优先级，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中，当存在多个BP时，任意两个BP上的SRS均可以采用本申请实施例提供的SRS的传输方法进行传输。比如，对于图1的(1a)中的激活的上行BP、SRS BP1、SRS BP2和SRS BP3，若SRS BP1上的SRS为周期性SRS，SRS BP2上的SRS为非周期SRS，则可以通过上述方式分别确定各个BP上的SRS的优先级，进而确定最终可以传输的SRS。示例性的，若SRS BP1上的SRS和激活的上行BP上的SRS发生传输冲突，则可以通过方式三确定激活的上行BP上的SRS的优先级低于SRS BP1上的SRS的优先级，从而丢弃激活的上行BP上的SRS；若SRS BP1上的SRS和SRS BP2上的SRS发生传输冲突，则可以通过方式五确定SRS BP1上的SRS的优先级低于SRS BP2上的SRS的优先级，从而丢弃SRS BP1上的SRS；若SRS BP2上的SRS和SRS BP3上的SRS发生传输冲突，则可以通过方式二确定SRS BP2上的SRS的优先级低于SRS BP3上的SRS的优先级，从而丢弃SRS BP2上的SRS。 此时，若没有其他BP上的SRS与SRS BP3上的SRS发生传输冲突，则终端可以从终端激活的上行BP切换到SRS BP3，在SRS BP3上传输SRS，从而可以获得SRS BP3的信道测量结果。
本申请实施例提供的SRS的传输方法中，在两个BP上的SRS发生传输冲突的情况下，可以丢弃SRS的优先级较低的SRS，也就是说，可以使得终端从激活的上行BP切换到传输优先级较高的SRS的BP上，在传输优先级较高的SRS的BP上传输SRS，因此可以实现SRS的BP级切换。
其中，上述步骤S501至S504中终端的动作可以由图4所示的通信装置40中的处理器401调用存储器402中存储的应用程序代码来执行，本申请实施例对此不作任何限制。
上述主要从各个网元之间交互的角度对本申请实施例提供的方案进行了介绍。可以理解的是，上述通信装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对通信装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
比如，以采用集成的方式划分各个功能模块的情况下，图7示出了上述实施例中所涉及的通信装置70的一种可能的结构示意图，该通信装置70包括：确定模块702和处理模块701。该确定模块702，用于确定第一BP上的SRS与第二BP上的SRS发生传输冲突；处理模块701，用于丢弃第一BP上的SRS，其中，第一BP上的SRS的优先级低于第二BP上的SRS的优先级。

在一种可能的实现方式中，确定模块702具体用于：根据第一时域资源、第二时域资源、第一RF切换时间和第二RF切换时间，确定终端从终端激活的上行BP切换到第一BP上时所需的时域资源和终端从终端激活的上行BP切换到第二BP上时所需的时域资源存在重叠部分，其中，第一RF切换时间为终端从终端激活的上行BP切换到第一BP上时所需的时间，第二RF切换时间为终端从终端激活的上行BP切换到第二BP上时所需的时间，第一BP和第二BP均为终端的SRSBP。
在一种可能的实现方式中，确定模块702具体用于：根据第一时域资源、第二时域资源和第三RF切换时间，确定终端从第一BP切换到第二BP时所需的时域资源包括第二时域资源，其中，第三RF切换时间为终端从第一BP切换到第二BP上时所需的时间，第一BP为终端激活的上行BP，第二BP为终端的SRSBP。
其中，上述方法实施例涉及的各步骤的所有相关内容均可以援引到对应功能模块的功能描述，在此不再赘述。

由于本申请实施例提供的通信装置70可用于执行上述SRS的传输方法，因此其所能获得的技术效果可参考上述方法实施例，在此不再赘述。
上述实施例中，该通信装置70以采用集成的方式划分各个功能模块的形式来呈现。当然，本申请实施例也可以对应各个功能划分通信装置的各个功能模块，本申请实施例对此不作具体限定。
可选的，本申请实施例提供了一种芯片系统，该芯片系统包括处理器，用于支持通信装置实现上述的SRS的传输方法，例如确定第一BP上的SRS与第二BP上的SRS发生传输冲突。在一种可能的设计中，该芯片系统还包括存储器。该存储器，用于保存通信装置必要的程序指令和数据。该芯片系统，可以由芯片构成，也可以包含芯片和其他分立器件，本申请实施例对此不作具体限定。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件程序实现时，可以全部或部分地以计算机程序产品的形式来实现。该计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行计算机程序指令时，全部或部分地产生按照本申请实施例所述的流程或功能。所述计算机可以是通用计算机、专用计算机、计算机网络、或者其他可编程装置。所述计算机指令可以存储在计算机可读存储介质中，或者从一个计算机可读存储介质向另一个计算机可读存储介质传输，例如，所述计算机指令可以从一个网站站点、计算机、服务器或者数据中心通过有线(例如同轴电缆、光纤、数字用户线(Digital Subscriber Line，DSL))或无线(例如红外、无线、微波等)方式向另一个网站站点、计算机、服务器或数据中心进行传输。所述计算机可读存储介质可以是计算机能够存取的任何可用介质或者是包含一个或多个可以用介质集成的服务器、数据中心等数据存储设备。所述可用介质可以是磁性介质(例如，软盘、硬盘、磁带)，光介质(例如，DVD)、或者半导体介质(例如固态硬盘(Solid State Disk，SSD))等。
尽管在此结合各实施例对本申请进行了描述，然而，在实施所要求保护的本申请过程中，本领域技术人员通过查看所述附图、公开内容、以及所附权利要求书，可理解并实现所述公开实施例的其他变化。在权利要求中，“包括”(comprising)一词不排除其他组成部分或步骤，“一”或“一个”不排除多个的情况。单个处理器或其他单元可以实现权利要求中列举的若干项功能。相互不同的从属权利要求中记载了某些措施，但这并不表示这些措施不能组合起来产生良好的效果。
尽管结合具体特征及其实施例对本申请进行了描述，显而易见的，在不脱离本申请的精神和范围的情况下，可对其进行各种修改和组合。相应地，本说明书和附图仅仅是所附权利要求所界定的本申请的示例性说明，且视为已覆盖本申请范围内的任意和所有修改、变化、组合或等同物。显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
