Description

通信方法和用户设备
本申请要求于2019年11月7日提交中国专利局、申请号为201911083130.5、申请名称为“通信方法和用户设备”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
本申请实施例涉及通信技术领域，尤其涉及一种上报探测参考信号(Sounding Reference Signal，SRS)能力信息的通信方法和用户设备。
背景技术
目前，用户设备(User equipment，简称UE)可以通过能力消息(UE Capability Information)和辅助消息(UE Assistance Information)上报用户天线转换的探测参考信号(Sounding reference signals，SRS)的转换能力信息，网络设备根据SRS天线转换能力信息为UE配置相应的SRS资源。
发明内容
本申请的一些实施方式提供了一种通信方法和用户设备。以下从多个方面介绍本申请，以下多个方面的实施方式和有益效果可互相参考。
当用户设备(User equipment，简称UE)出现设备内部过热问题，可以通过降低UE能力或配置来降温解决过热问题，此时，UE可以上报辅助信息(UE Assistance Information)通知网络设备(例如，基站)UE期望降低的能力或配置，供基站参考、进行重配。例如，当过热相关的辅助信息包括UE的多输入多输出(multiple input multiple output，MIMO)层(layer)数时，网络设备可以为UE重新配置低能力的MIMO layer数，用于UE按低能力的MIMO layer数关闭部分射频链路及天线端口，以降低UE的功耗解决过热问题。但是，在网络设备为UE调低MIMO layer数后，如果网络设备不相应的重配用于用户天线转换的探测参考信号(Sounding reference signals，SRS)资源，在进行天线端口转换时，会出现能力不匹配的问题，从而导致UE无法真正降温，浪费某些SRS资源，和/或影响通话质量的问题。
为了应对上述场景，第一方面，本申请的实施方式提供了一种用于用户设备(UE)的通信方法，用于将回退的SRS天线转换能力信息和载波关联起来。该方法包括：确定用于UE的可回退的信道探测参考信号(SRS)天线转换能力信息，例如，可回退的SRS天线转换能力信息指示UE支持的用于传输SRS的天线端口转换能力，天线端口转换能力包括UE能够传输SRS的天线和天线端口的数量中的至少一个，并且可回退的SRS天线转换能力信息意味着上述能力等于或小于预设的用于传输SRS的天线和天线端口的数量中的至少一个；其中，可回退的SRS天线转换能力信息与UE支持的一 个或多个载波和/或至少一个小区对应。
之后，向网络设备发送可回退的SRS天线转换能力信息。
根据本申请的实施方式，将根据UE支持的载波和/或当前配置的载波确定与载波对应的可回退的SRS天线转换能力信息上报在网络设备，实现以UE的载波为粒度的SRS能力的相关配置。使得在相关配置的过程中,UE和网络设备之间的网络通信的信令开销更小，并且配置过程更加符合UE在载波上工作的实际情况。
在一些实施方式中，具体来说，UE能够传输SRS的天线和天线端口包括：UE能够通过一个或多个载波和/或至少一个小区，传输SRS的天线和天线端口。
在一些实施方式中，可回退的SRS天线转换能力信息还指示：对应于一个或多个载波中的每一个载波，转换天线端口对于一个或多个载波中的其他载波中的上行载波的影响，和/或转换天线端口对于一个或多个载波中的其他载波中的下行载波的影响。
在一些实施方式中，通过比特图指示上述影响，在比特图中每一元素与载波/小区的对应关系按照预先确定好的顺序排列。例如，对应于一个或多个载波中的每一个载波，上行载波的影响和下行载波的影响中的至少一个包括一个或多个比特位，其中一个或多个比特位与一个或多个载波一一对应。
在一些实施方式中，还可以通过信息包的方式对每个载波的可回退的SRS天线转换能力信息打包，例如，在可回退的SRS天线转换能力信息与多个载波和/或多个小区相对应的情况下，可回退的SRS天线转换能力信息包括多个可回退的SRS天线能力信息包，其中多个可回退的SRS天线能力信息包与多个载波和/或多个小区一一对应，并且，多个可回退的SRS天线能力信息包中的每一个指示天线端口转换能力，对上行载波的影响和对下行载波的影响中的至少一个。

图1实施本申请示意性的实施例的通信***100的示意图。该通信***100可以包括至少一个UE 10(仅示出一个)和至少一个网络设备12(仅示出一个)。例如UE10可以基于蜂窝通信协议与网络设备12通信地耦接，蜂窝通信协议例如可以是全球移动通信***(GSM)协议、码分多址(CDMA)网络协议、即按即说(PTT)协议、蜂窝PTT(POC)协议、通用移动电信***(UMTS)协议、3GPP长期演进(LTE)协议、第五代(5G)协议、新无线电(NR)协议等。
如图1所示，UE 10可以包括用户使用的终端设备，例如，手机、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
UE 10还包括：处理器102、通信模块104和存储器106，这些模块通过总线通信地耦接。处理器102可以包括但不限于中央处理器CPU(Central Processing Unit)、图像处理器GPU(Graphics Processing Unit)、数字信号处理器DSP、微处理器MCU(Micro-programmed Control Unit)、AI(Artificial Intelligence)处理器或可编程逻辑器件FPGA(Field Programmable Gate Array)等的处理模块或处理电路。在一些实施例中，处理器102可以被配置为执行下文描述的各种实施例的一个或多个实施例。
在一种可能的实施方式中处理器102可以运行UE 10的操作***，例如，Android、iOS、Windows OS、Liunix和鸿蒙操作***等。在另一些可能的实施方式中，处理器102可以运行特定的应用程序。
存储器106可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器106可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至UE 10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
通信模块104可以包括控制单元1041和收发单元1042。控制单元1041可以处理从收发单元1042接收的无线信号，并生成用于收发单元1042发送的无线信号。在一些实施方式中，控制单元1041可以包括第三代(3G)基带处理器、***(4G)基带处理器、第五代(5G)基带处理器，和/或用于其他现有代、在开发中或未来将要开发的代(例如，第六代(6G)等)的(一个或多个)其他基带处理器。控制单元1041可以处理经由收发单元1042与一个或多个无线电网络进行通信的各种无线电控制功能。在一些实施方式中，通信模块104可以提供与一个或多个无线电技术兼容的通信。收发单元1042可以包括射频链路，例如，包含三级射频集成电路、功率放大器以及双工器/ 滤波器等。
网络设备12可以包括用于与UE通信的网络侧设备，例如，宏基站、微基站或者分散单元-控制单元(distribute unit-control unit，DU-CU)等。其中，基站可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB，)，也可以是NR中的gNB等。基站还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者可以为中继站、接入点、车载设备、可穿戴设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的网络设备等，DU-CU是一种部署在无线接入网中能够和用户设备进行无线通信的设备。本申请实施例对此并不限定。
在通信***100中，例如UE 10出现过热问题或需要降低功耗节省电池寿命的时候，UE可以上报UE辅助信息(UE Assistance Information)通知网络设备该UE期望降低的能力或配置，供基站参考、进行重配。以UE 10过热为例：
通常，网络设备12向UE 10发送RRC(Radio Resource Control，无线资源控制)连接重配消息。其中，该RRC连接重配置消息可以包括：过热相关的配置信息。例如，过热相关的配置信息可以指示UE 10是否可以发送过热相关的辅助信息给网络设备12，以及过热相关的禁止定时器的取值等。
若网络设备12配置UE 10可以发送过热相关的辅助信息，当UE 10出现过热问题，且过热相关的禁止定时器不在运行状态，UE 10向网络设备发送辅助信息消息。其中，该辅助信息消息中包括过热相关的辅助信息，用于网络设备12解决UE 10的过热问题。
可以理解，过热相关的辅助信息的内容可以根据实际需求配置，本申请实施例对此并不进行具体限定。当过热相关的辅助信息包括UE类型或MIMO layer数，即用于指示UE期望降低MIMO layer数时，网络设备可以根据UE上报的UE类型或MIMO layer数，给UE重新配置合适的MIMO layer数。
在上述降低UE能力或配置的过程中，网络设备根据UE的上报仅重新配置MIMO layer数，UE降低的MIMO layer数关闭射频链路及天线端口存在弊端，会影响UE正常能力下的SRS能力。比如，若网络设备配置UE降低上行最大MIMO layer数，UE会关闭发射射频链路，这时，UE无法支持正常能力下的天线轮发SRS，从而导致某些SRS资源的浪费。若网络设备配置UE降低下行最大MIMO layer数，UE期望关闭部分接收射频链路，这时UE仍然按照正常能力下的天线轮发SRS，就会导致网络设备根据SRS估计的信道质量与调度物理下行共享信道(physical downlink shared channel，PDSCH)传输的下行信道质量不一致。因此，即使网络设备为UE重配了低能力的MIMO layer数，UE为了实现SRS天线转换能力，仍然要保持原来的射频链路及天线端口数目，UE的功耗无法降低，网络设备为UE重新配置的低能力的MIMO layer数也无法发挥降温的作用。
因此，在通信***100中，UE 10需要将自身支持的可回退的SRS天线转换能力信息上报给网络设备12，以便网络设备12可以根据UE 10上报的可回退的SRS天线转换能力信息配置对应的SRS资源。以下参见图2具体描述UE 10上报可回退的SRS天线转换能力信息上报给网络设备12。
可以理解，本申请的实施方法可以应用于任一UE需上报可回退的SRS能力的场景中，UE发生过热问题或者需降低功耗仅是示例的应用场景，并不是对本申请方案的应用场景的具体限定，后续内容对此不再一一说明。
以下参考图2描述根据本申请实施例的示例通信***100的通信方法的流程示意图。
如图2所示，在块201，网络设备12向UE 10发送能力请求(UE Capability Enquiry)消息，用于请求UE发送UE在某一/些RAT的无线接入能力。
在块202，响应于网络设备12的能力请求消息，UE 10确定自身的无线能力(radio capability)，并通过能力消息(UE Capability Information)向网络设备12上报自身的无线能力(radio capability)。UE的能力消息中可以包含该UE在多种无线接入技术(Radio Access Technology，RAT)中的能力。能力消息可以在UE 10接入网络设备12所在的小区时进行上报，也可以在网络设备12需要了解UE 10的无线能力时，指令UE 10进行上报。
在一些实施方式中，UE 10的能力消息可以由通信模块104的控制单元1041生成，并经由收发单元1042发送给网络设备12。可以理解，在本申请的一个或多个实施方式中，通信模块104可以对UE 10进行各种与无线通信相关的配置。
在一些实施方式中，能力消息中可以包括UE 10预设的SRS天线转换/轮发(sounding reference signal antenna switch)能力，即UE 10期望被配置的能力。其中，该能力指示了UE 10向网络设备12发送SRS时可以支持的天线数量和天线端口数量。
在可选的或附加的一些实施方式中，能力消息中还可以包括UE 10支持的可回退的SRS天线转换能力。
在现有标准中，网络设备12并不明确知道UE 10有多少射频链路，而是采用天线这一术语进行描述。比如当UE 10实际有两个发射射频链路的时候，该UE 10最多支持同时使用2个天线与网络设备12进行上行通信。如果UE 10使用2个天线与网络设备12进行通信，则在实际上每个射频链路会对应一个天线。如果UE 10使用1个天线与网络设备12进行通信，UE 10可以使用任意一个上行射频链路对应到这个天线，也可以同时使用两个射频链路模拟成一个天线，这取决于UE 10的具体实现，对网络设备12而言是透明的。网络设备12只需要调度UE 10在哪个或哪些天线上发送数据即可。下面为了简化描述，将一个UE 10支持一个发射射频链路(transmit，T)，两个接收射频链路(receive，R)称为t1r2。以此类推，一个UE 10支持2个发射射频链路和4个接收射频链路称为t2r4。通常情况下，UE 10中的接收射频链路数量会大于或等于发射射频链路数量，并且每一个接收射频链路与一根天线(即电磁波的辐射单元)连接，因此t1r2也可以理解为该UE 10中有一个发射射频链路与两根天线。以此类推，t2r4也可以理解为该UE 10中有两个发射射频链路与四根天线。因此，SRS能力信息中的天线数量也可以理解为接收射频链路/接收天线的数量，天线端口数量也可以理解为发射射频链路/发射天线的数量。这里所述的天线具有发射电磁波与接收电磁波的能力，因此本申请实施例中的天线、发送天线以及接收天线可视为同一事物。
对于UE 10的SRS天线转换能力而言，由于不同的UE硬件配置不相同，基于硬件配置，UE的天线轮发能力也是不一样的。在NR中规定SRS天线轮发能力如下：t1r2、 t1r4、t2r4、t1r4-t2r4、t1r1、t2r2或t4r4等。下面举例说明，t1r2为UE中有一个发射射频链路与两根天线，此时UE每次可以使用单端口发送一个SRS，完成轮发需要发送两次，即第一次发送SRS使用第一发射射频链路与第一天线，第二次发送SRS使用第一发射射频链路与第二天线。t2r4为UE有两个发射射频链路与四根天线，此时UE每次可以使用双端口发送一个SRS，完成轮发需要发送两次，即第一次发送SRS使用第一发射射频链路与第二发射射频链路以及第一天线与第二天线，第二次发送SRS使用第一发射射频链路与第二发射射频链路以及第三天线与第四天线。t1r4-t2r4为该UE既支持t1r4的SRS天线轮发也支持t2r4的SRS天线轮发。
根据本申请的各种实施方式，UE 10预设的SRS天线转换能力和针对预设的SRS天线转换能力的可回退的SRS天线转换能力可以针对UE 10的载波进行配置和上报。
可以理解，本文的通信***100可以支持多个小区或载波的操作，此特征可以被称为载波聚合(Carrier Aggregation，CA)或多载波操作。载波还可以被称为分量载波(component carrier，CC)、层、信道等。本申请中，术语“载波”、“分量载波”、和“小区”(在没有上行补充链路Supplementary UL，SUL的场景中)在本文中可以可互换地使用。载波可以或可以不与彼此相邻。载波的分配可以是关于DL和UL不对称的(例如，与UL相比，可以为DL分配更多或更少的载波)。分量载波可以包括主分量载波(简称主载波)和一个或多个辅分量载波(简称辅载波)。主分量载波可以被称为主小区(PCell)，并且辅分量载波可以被称为辅小区(SCell)。
在无线通信中，UE 10可以使用一个或多个载波，即UE 10可以在该一个或多个载波上工作。根据可以用于指示载波的标识信息，可以为UE 10支持的每个载波配置SRS天线转换机制。指示载波的标识信息例如包括：载波标识(identity，ID)，和/或载波的辅小区索引(SCellIndex)。作为一个示例，对于主载波/主小区的辅小区索引可以配置为索引值为SCellIndex＝0，而辅载波/辅小区的辅小区索引的索引值可以依次设置为没有被其他辅载波/辅小区占用的值，例如，SCellIndex＝1，SCellIndex＝3等等，如此，载波可以由辅小区索引指示。
在一些实施方式中，UE 10可以上报针对支持的一个或多个载波和/或一个或多个小区的SRS天线转换能力和/或可回退的SRS天线转换能力。
作为一个示例，在SRS天线转换能力信息中，按照UE 10上报支持的一个或多个载波的默认顺序，排列一个或多个载波对应的SRS天线转换能力和/或可回退的SRS天线转换能力。SRS天线转换能力信息中无需体现SRS天线转换能力和/或可回退的SRS天线转换能力与载波的对应关系，网络设备12根据UE 10的载波的默认顺序，即可确定上述能力与载波的对应关系，即确定UE 10在哪个载波上支持的SRS天线转换能力和可回退的SRS天线转换能力分别是什么。
默认顺序可以为预先规定的可支持的载波的顺序，或者也可以是UE 10的能力信息中载波上报的顺序，例如，按照载波的ID排序后的顺序，或者按照载波的辅小区索引排序后的顺序，排序可以根据ID和/或索引的大小或其他方式进行，本申请实施例对此不进行具体限定。
在一些实施方式中，例如，假设UE 10支持3个载波，分别为(主)载波1、(辅)载波2和3，其中，主载波1的SCellIndex＝0，辅载波2的SCellIndex＝1，辅载波3的 SCellIndex＝3。那么如果，UE 10按照辅载波索引从小到大的顺序上报载波1-3，则与载波对应的SRS天线转换能力信息的顺序可以为：UE 10在载波1支持的SRS天线转换能力1、UE 10在载波2支持的SRS天线转换能力2、UE10在载波3支持的SRS天线转换能力3。作为另一个示例，UE 10的SRS天线转换能力信息中每个载波对应的SRS天线转换能力可以以集合或列表的方式统一上报，例如，SRS天线转换能力信息可以是{UE 10在载波1支持的SRS天线转换能力1、UE 10在载波2支持的SRS天线转换能力2、UE10在载波3支持的SRS天线转换能力3}。
在另一些实施方式中，可以将指示载波的标识信息与载波的SRS天线转换能力一一对应。例如，同样假设UE 10支持3个载波，分别为(主)载波1、(辅)载波2和3，其中，主载波1的SCellIndex＝0，辅载波2的SCellIndex＝1，辅载波3的SCellIndex＝3。在SRS天线转换能力信息中可以包括多个信息包，每个信息包对应一个载波，例如：信息包1{SCellIndex 0，UE 10在载波1支持的SRS天线转换能力1}、信息包2{SCellIndex 1，UE 10在载波2支持的SRS天线转换能力2}、信息包3{SCellIndex 3，UE 10在载波3支持的SRS天线转换能力3}。作为另一个示例，每个载波对应的SRS天线转换能力可以以集合或列表的方式统一上报，例如，SRS天线转换能力信息可以是{SCellIndex 0，UE 10在载波1支持的SRS天线转换能力1；SCellIndex 1，UE 10在载波2支持的SRS天线转换能力2；SCellIndex 3，UE 10在载波3支持的SRS天线转换能力3}。
需要说明的是，上述示例只是通过举例的形式描述SRS天线转换能力信息与载波的对应关系，并不是对SRS天线转换能力信息内容的限定。
类似地，对于UE 10支持的可回退的SRS天线转换能力可以按照与上述SRS天线转换能力相同的对应方式进行上报，网络设备12根据如上所述的方式即可以确定UE 10在每个载波上支持的可回退的SRS天线转换能力是什么。可回退的SRS天线转换能力信息的上报过程将参考图3描述。
可以理解，在上述各个实施方式中，在UE 10支持的一个或多个载波中可能存在不支持SRS能力的载波，例如，UE 10支持的主载波1支持SRS天线转换能力，但存在辅载波2和3其中至少一个载波不支持SRS天线转换能力的情况，在这种情况下，SRS天线转换能力信息和/或可回退的SRS天线转换能力信息可以仅包括具备SRS天线转换能力的载波的SRS天线转换能力和/或相应的回退能力。
根据本申请的另一些实施方式，SRS天线转换能力信息和可回退的SRS天线转换能力信息还可以包括UE 10支持的一个或多个载波/一个或多个小区的天线转换能力/回退的天线转换能力对其他下行载波的影响和/或对其他上行载波的影响。以下参考图3具体描述这些影响。
在上述实施方式中，UE 10向网络设备12上报UE 10支持的SRS天线转换能力信息，该信息根据UE 10支持的一个或多个载波/一个或多个小区来配置。
在块203，网络设备12接收UE 10发送的SRS天线转换能力信息。网络设备12接收的内容即为上述块202中描述的内容，在此不再赘述。
在块204，网络设备12根据UE 10发送的SRS天线转换能力信息，向UE 10发送配置信息。网络设备12可以为UE 10配置SRS资源。例如，网络设备12为UE 10 配置/重配置SRS天线转换能力时，可以参考UE 10发送的上述信息为UE 10对应地配置用于天线端口转换的SRS资源。当然，网络设备12也可以配置其他，本申请对此不进行具体限定，对于配置的具体过程不进行赘述。
在块205，UE 10接收并执行配置信息。
根据本申请的另一些实施方式，以下参考图3描述UE 10想要降低SRS天线转换能力的时候，上报可回退的SRS天线转换能力信息的示例。
图3示出了UE 10通过UE辅助信息(UE Assistance Information)上报可回退的SRS天线转换能力信息的示例。
在块301，网络设备12向UE 10发送RRC连接重配消息。在块302，UE 10确定是否需要降低SRS天线转换能力。在需要降低能力的情况下，在块303，UE 10向网络设备12发送辅助信息。在一些实施方式中，在RRC消息中可以包括网络设备12为UE 10预先配置的SRS天线转换能力信息，也可能包括UE 10的载波配置，例如，在上述块205中UE 10接收的配置信息。在另一些实施方式中，例如UE 10出现过热问题或需要降低功耗节省电池寿命的时候，在RRC消息中可以包括上文描述的过热相关的配置信息，对应RRC连接重配消息和辅助信息的其他内容可以参考上文的内容，在此不再赘述。
在辅助信息中UE 10可以上报UE 10当前配置的载波的可回退的SRS天线转换能力信息。
在一些实施方式中，对于UE 10的可回退的SRS天线转换能力而言，该能力可以由UE 10根据其硬件配置和/或当前SRS资源配置情况确定上报。例如，UE 10当前的SRS天线转换能力配置为2T4R，即UE 10能够通过4个天线在2个天线端口上传输SRS；相应的，UE 10支持的可回退的SRS天线转换能力可以为1T4R和/或1T2R，即UE 10的SRS天线转换能力为通过4个天线在1个天线端口上传输SRS和/或UE 10的SRS天线转换能力为通过2个天线在1个天线端口上传输SRS。
根据本申请的实施方式，可回退的SRS天线转换能力信息可以包括一种或多种UE 10期望的回退的SRS能力。例如，UE 10期望的回退的能力的最大值，或者UE 10期望的回退的能力的绝对值。
作为一个示例，例如，在UE 10上报的SRS天线转换能力为t4r4的情况下，如果在可回退的SRS天线转换能力信息中，UE 10期望的回退的能力的最大值为t2r4，则UE 10可以请求网络设备12向其配置小于或等于t2r4的回退能力，即，UE 10可配置的回退能力包括t1r4和/或t1r2，这样，UE 10期望的天线端口和天线的数量为一种或多种。如果在可回退的SRS天线转换能力信息中，UE 10期望的回退的能力的绝对值为t2r4，则UE 10可以请求网络设备12向其配置等于t2r4的回退能力，即UE 10可配置的回退能力仅有一种。
需要说明的是，UE可以根据网络需求或者场景需求，来确定回退的天线端口和天线的数量，进而确定SRS天线转换能力信息，本申请实施例对于该过程不进行具体限定。
例如，UE可以在发生过热时，根据当前设备温度以及理想温度，得到期望降低的功耗值，再按照预设的功耗与SRS天线转换能力的映射关系，确定回退的天线端口和 天线的数量，进而确SRS天线转换能力信息。当然，此处只是以过热场景下的一种实现举例，并不对应用场景以及实现方式构成限定。
根据本申请的一些实施方式，针对UE 10支持的每个载波的可回退的SRS天线转换能力，UE 10可以仅在可回退的SRS天线转换能力信息中上报一个UE 10期望的回退的SRS能力的值，该回退的能力的值可以用于UE 10支持的所有载波。在这种情况下，可回退的SRS天线转换能力信息中无需体现该回退能力与载波的对应关系。可以理解，该回退的SRS天线转换能力的值需要小于或等于UE 10上报的所有SRS天线转换能力中最小的能力的值。此外，该回退的能力的值也可以是UE 10期望的回退的能力的最大值，或者UE 10期望的回退的能力的绝对值，在此不再赘述。
根据本申请的另一些实施方式，SRS天线转换能力信息和可回退的SRS天线转换能力信息还可以包括UE 10支持的一个或多个载波/一个或多个小区的天线转换能力/回退的天线转换能力对其他下行载波的影响和/或对其他上行载波的影响。针对回退的天线转换能力对其他下行载波的影响为例，描述如何在可回退的SRS天线转换能力信息中表示该影响。可以理解，以下描述同样可用于可回退的SRS天线转换能力信息中对其他上行载波的影响以及在SRS天线转换能力信息中对其他下/上行载波影响，以下不一一列举。
在一些实施方式中，可以通过1-32个整数来体现回退的天线转换能力对其他下行载波的影响，其中，在现有标准中，最多可以配置32个载波，因此可以使用1-32个整数来表示可配置的全部载波。例如，同样假设UE 10支持3个载波，分别为(主)载波1、(辅)载波2和3，那么可以最多使用1-3的整数表示载波间的影响。如果将载波1的其他下行载波的影响的值设置为1，并且假如载波1对载波2没有影响，载波1对载波3有影响，那么载波3的其他下行载波的影响的值需要设置为1，即设置的值与载波1的其他下行载波的影响的值相同，载波2的其他下行载波的影响的值可以设置为1以外的值，例如，2或3。
每个载波的回退的天线转换能力对其他下行载波的影响也可以通过前述实施方式中描述的各种的载波与能力的对应关系来上报给网络设备12。例如，按照UE 10上报支持的一个或多个载波的默认顺序，排列一个或多个载波对应的对其他下行载波的影响，以及将指示载波的标识信息与载波的回退的天线转换能力对其他下行载波的影响一一对应，具体参见前述描述，在此不再赘述。
在另一些实施方式中，还可以通过比特位体现回退的天线转换能力对其他下行载波的影响。例如，对其他下行载波的影响通过比特图表示，在每个载波的比特图中，按照UE 10上报支持的一个或多个载波的默认顺序，设置比特位，比特图中的每一位表示一个载波，其中比特0表示无影响，比特1表示有影响。还是假设UE 10支持3个载波，分别为(主)载波1、(辅)载波2和3，如果UE 10按照辅载波索引从小到大的顺序上报载波1-3，那么每个载波的比特图为{载波1，载波2，载波3}。例如，载波1的回退的天线转换能力对载波3有影响，对载波2没有影响，那么载波1的比特图可以为{1，0，1}，相应地，载波2的比特图为{0，0，0}，载波3的比特图为{1，0，1}。作为另一个示例，还可以在每个载波的可回退的SRS天线转换能力信息中仅使用比特图{1，0，1}表示每个载波的对其他下行载波的影响。
在另一些实施方式中，还可以通过用于指示载波的标识信息，例如载波ID、辅小区索引等表示载波的回退的SRS天线转换能力对其他上/下行载波的影响。在这种情况下，假设UE 10支持3个载波，分别为(主)载波1、(辅)载波2和3，其中，主载波1的SCellIndex＝0，辅载波2的SCellIndex＝1，辅载波3的SCellIndex＝3。载波1的回退的天线转换能力对载波3有影响，对载波2没有影响，那么在可回退的天线转换能力信息中，对其他上/下行载波的影响可以包括{SCellIndex 0，SCellIndex 1}，指示载波1对载波3有影响。
在可选的或附加的实施方式中，可回退的SRS天线转换能力信息还可以采用在上文描述的信息包，每个信息包通过载波的标识信息与各个载波一一对应，在信息包中不仅包括上文中描述的天线端口转换能力，还可以包括对上行载波的影响和对下行载波的影响中的至少一个。作为一个示例，载波1的信息包可以为{SCellIndex 0，UE 10在载波1支持的SRS天线转换能力1，载波1对其他下行载波的影响，载波1对其他上行载波的影响}，以上信息包的格式仅作为示例用于说明，并不作为本申请对信息包的任何限定。
UE 10针对当前配置的一个或多个载波，即UE 10当前使用的载波上报可回退的SRS天线转换能力信息。其中，在可回退的SRS天线转换能力信息中，UE 10当前配置的每个载波的回退的SRS天线转换能力和/或对其他上/下行载波的影响可以一一对应，对应的方式可以参考上述描述，在此不再赘述。
对于UE 10当前配置的载波，网络设备12可以根据自身配置的规则在任意UE 10所需的时候为UE 10配置载波，该规则可以基于现有标准，本申请对于规则的配置方法以及规则内容不进行具体限定。
块304-306中描述的内容与块203-205类似，在此不再赘述。
以下参考图4描述示例通信***100的另一种通信方法。
根据本申请的实施方式，图4提供另一种上报可回退SRS天线转换能力相关的方法。在块401，网络设备12向UE 10发送RRC连接重配消息。本实施方式中的内容与块301相似，此处不再赘述。
在块402，UE 10确定是否需要降低SRS天线转换能力。在需要降低能力的情况下，在块403，UE 10向网络设备12发送辅助信息。在辅助信息中UE 10可以上报UE 10针对当前配置的载波的可回退的载波配置，以及回退的载波配置的可回退的SRS天线转换能力信息。
作为一个示例，假设UE 10当前配置有3个载波，分别为载波1、载波2和载波3。UE 10可以根据当前的过热情况和配置规则，任意回退最多n-1个载波，其中n为当前配置的最大载波数，生成回退的载波配置信息。可以理解，UE 10的配置规则可以基于现有标准，本申请对于规则的配置方法以及规则内容不进行具体限定。
可以理解，回退的载波配置信息可以包括载波标识(identity，ID)，载波数量，载波的频点信息，和/或载波的带宽信息等。凡是可以用于指示回退的载波的信息，都可以包括在本文所称的载波配置信息中，例如，载波的辅小区索引(SCellIndex)，对于主载波/主小区的辅小区索引可以配置为索引值为SCellIndex＝0，而辅载波/辅小区的辅小区索引的索引值可以依次设置为没有被其他辅载波/辅小区占用的值，例如， SCellIndex＝1，SCellIndex＝3等等。
之后，根据该回退的载波配置信息，UE 10可以进一步为回退的载波提供与载波对应的可回退的SRS天线转换能力信息。与载波对应的可回退的SRS天线转换能力信息可以参考前述实施方式的详细描述，在此不再赘述。
在块404，网络设备12接收回退的载波配置和与载波配置对应的可回退的SRS天线转换能力信息。本实施方式中的内容与块304相似，此处不再赘述。
在块405，网络设备12根据UE 10发送的回退的载波配置和可回退的SRS天线转换能力信息，向UE 10发送配置信息。例如，网络设备12为UE 10重配置载波和SRS天线转换能力时，可以参考UE 10发送的上述信息，为UE 10配置回退的载波以及与回退的载波对应的用于天线端口转换的SRS资源。
在块406，UE 10接收并执行配置信息。
需要说明的是，本申请实施例提供的上报SRS能力的方法所包括的上述一个或多个块，可以根据实际需求配置执行顺序，图2-图4中仅示意了一种可能的执行顺序，并不是对此的具体限定。
根据本申请的各种实施方式，将根据UE支持的载波和/或当前配置的载波确定与载波对应的SRS天线转换能力信息和/或可回退的SRS天线转换能力信息上报在网络设备，实现以UE的载波为粒度的SRS能力的相关配置。使得在相关配置的过程中,UE和网络设备之间的网络通信的信令开销更小，并且配置过程更加符合UE在载波上工作的实际情况。
此外，根据本申请的各种实施方式，还可以实现UE根据当前载波配置工作时，网络设备基于UE上报的回退载波配置和/或可回退的SRS天线转换能力信息为UE进行相关配置，能够邮箱降低UE的功耗，解决UE过热问题，并延长UE使用时间。
