现结合附图和具体实施方式对本公开实施例进一步说明。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。

下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
如图1所示，本公开实施例提供的一种传输能力信息的方法可应用于无线通信系统100， 该无线通信系统可以包括用户设备101和网络设备102。其中，用户设备101被配置为支持载波聚合，并可连接至网络设备102的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信系统100既可适用于低频场景，也可适用于高频场景。无线通信系统100的应用场景包括但不限于长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信系统、云无线接入网络(cloud radio access network，CRAN)系统、未来的第五代(5th-Generation，5G)系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示用户设备101可以是终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该用户设备101可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信)，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备102。
其中，用户设备101可以是蜂窝电话、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)设备、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、未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。
网络设备102可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备102具体可包括基站(base station，BS)，或包括基站以及用于控制基站的无线资源管理设备等。该网络设备102还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的通信芯片。
比如，网络设备102包括但不限于：5G中的下一代基站(gnodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、WCDMA系统中的节点B(node B，NB)、CRAN系统下的无线控制器、基站控制器(basestation controller，BSC)、GSM系统或CDMA系统中的基站收发台(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)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。
以图2为例进行说明，结合图2所示，用户设备101支持1发4收(1T4R)模式，即 用户设备101具备一个收发共用天线(或称主集天线)201，三个接收天线(或称分集天线)202。收发共用天线201通过主收发模块203进行发射信号(如SRS)时，信号路径经过路径1，路径1上包含单刀四掷开关(SP4T)205元件。任一接收天线202与对应的分集接收模块204连接，以接收信号。
而在SRS天线切换场景中，接收天线202需要切换至与主收发模块203连接以发射SRS，此时SRS信号路径变为虚线的路径2，该路径2上包括单刀四掷开关(SP4T)205元件以及单刀双掷开关(SPDT)206元件。其中，每个接收天线202对应的路径2-1、路径2-2和路径2-3的长度也可能不同。
在图2示例的基础上可知，在SRS天线切换场景中，切换接收天线202来发射SRS的路径，相较于收发共用天线201发射SRS的路径，额外增加了SPDT206的插损以及额外的线路损耗。
现有协议针对SRS天线切换场景定义了统一的插损(ΔT RxSRS)，例如在小于4.4GHz的频段ΔT RxSRS为3dB，在大于或等于4.4GHz的频段ΔT RxSRS为4.5dB，该ΔT RxSRS是根据对比各个天线上额外插损，取最大值得出的。也就是说，基于现有协议不同的UE在由收发共用天线201切换至接收天线202时，基站在进行下行信道估计或者UE计算最大可配置功率(Pcmax)的过程中，考虑在接收天线202对应的测量结果上补偿该统一的ΔT RxSRS。
但对于不同的UE，以及UE内部的不同信号路径，采用统一的插损ΔT RxSRS进行信道估计可能会带来较大的误差，影响信道估计的准确性。并且，随着UE中接收天线数量的增加(如8R)，ΔT RxSRS会更大。因此，需要提供更准确的进行信道估计的方法。
本公开实施例提供了一种传输能力信息的方法。参照图3，图3是根据一示例性实施例示出的一种传输能力信息的方法，如图3所示，该方法包括步骤S301～S302，具体的：

在一示例中，下行信道质量的参数包括但不限于SRS的参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)、信号噪声干扰比(Signal to Interference plus Noise Ratio，SINR)或者接收信号强度指示(Receive Signal Strength Indication，RSSI)。在采用插损参数进行补偿时，可以结合每种质量参数的计算方式进行补偿，例如，在质量参数上增加或减去对应的插损参数。
本公开实施例中，用户设备101通过向网络设备102上报能力信息，上报SRS天线切换场景中接收天线对应的插损参数，从而网络设备102可以获知该用户设备101接收天线的插损参数，以便于网络设备基于该用户设备接收天线的插损参数进行更合理的处理，如进行更准确的信道估计。

在一些可能的实施方式中，N等于1，即能力信息中通过1个比特指示插损参数。
在一示例中，插损参数为插损值。该1个比特值为0时，对应指示插损值为3dB；该一个比特值为1时，对应指示插损值为4dB。
在一示例中，插损参数为插损值范围。该1个比特值为0时，对应指示插损值范围为0～4dB；该一个比特值为1时，对应指示插损值范围为4～6dB。
在一些可能的实施方式中，N等于2，即能力信息中通过2个比特指示插损参数。

在一些可能的实施方式中，能力信息中上报插损参数时，可能适用多个频段。

在一些可能的实施方式中，能力信息中包括多个频段分别对应的信息域，每个信息域中可以包括N个比特。
在一些可能的实施方式中，每个频段下对应上报一个插损参数。其中，可通过1个比特或2个比特指示某一个频段对应的插损参数。

其中，能力信息包括第一频段下对应的至少一个插损参数。
在一些可能的实施方式中，该至少一个插损参数可以对应不同的接收天线。
在一些可能的实施方式中，能力信息中插损参数的个数与用户设备101的能力相关。
在一示例中，用户设备101支持1T2R，则可以上报一个插损参数。该一个插损参数适用第一频段，以及除收发共用天线外的一个接收天线。
在一示例中，用户设备101支持1T4R，则可以上报两个或三个插损参数，每个插损参数对应一个接收天线。
在一些可能的实施方式中，由网络设备102根据能力信息，确定插损参数适用的接收天线。
在一些可能的实施方式中，用户设备101在能力信息中同时上报接收天线的标识以及该接收天线对应的插损参数。
在一些在可能的实施方式中，插损参数包括以下中的一项：插损值，插损值范围。
可以理解的，在多个频段中每个频段对应有插损参数的场景中，若任一频段下对应多于一个的插损参数，其实施方式可参见第一频段对应的实施例。
本公开实施例中，用户设备101可以在某个频段上报至少一个插损参数，从而可以对应到不同的接收天线，即不同的接收天线对应的插损参数可能不同，以进一步提升每个天线对应信道估计的准确性。
本公开实施例提供了一种发送能力信息的方法，该方法被用户设备101执行。参照图5，图5是根据一示例性实施例示出的一种发送能力信息的方法，如图5所示，该方法包括步骤S501～S502，具体的：
步骤S501，用户设备101根据SRS天线切换能力以及网络设备102发送的配置信息，确定能力信息，配置信息中包括SRS端口数。
步骤S502，用户设备101向网络设备102发送能力信息。

在一些可能的实施方式中，网络设备102下发的配置信息包括配置的SRS资源集(SRS resources set)，SRS resources set中包括SRS资源和该资源关联的SRS端口(SRS port)数。用户设备101在天线轮发过程中，每个天线依据对应的SRS资源发送SRS。
在一些可能的实施方式中，SRS端口表征逻辑端口，可以映射到物理天线端口。

步骤S501’，根据用户设备支持的收发共用天线的数量以及SRS的端口数，确定插损参数的数量M，以确定包括M个插损参数的能力信息。
该实施方式中，SRS端口数一般为1个、2个或4个。
该实施方式中，用户设备的SRS天线切换能力(SRS-TxSwitch capability)即可表征其支持的收发共用天线的数量。
为便于理解本公开实施例，以下结合表3列举三个示例进行说明。
在第一个示例中：
结合表3所示，在用户设备支持收发共用天线的数量最大为1，例如SRS天线切换能力对应1T2R或者1T1R转1T2R时，用户设备101支持1个收发共用天线(天线1)和1个接收天线(天线2)。其中，收发共用天线即支持同时接收和发射信号的天线。
本示例中，SRS端口数为1，表明用户设备101最多支持1个天线同时执行发送。此时M＝1，即仅为该一个接收天线(天线2)配置插损参数即可。
在第二个示例中：
结合表3所示，在用户设备支持收发共用天线的数量最大为2，例如SRS天线切换能力对应1T4R、或者1T4R转2T4R、或者1T1R转1T2R转1T4R、或者1T1R转1T2R转2T2R转1T4R转2T4R时，用户设备101支持1个收发共用天线(天线1)和3个接收天线(天线2、天线3和天线4)。
本示例中，SRS端口数为1，表明用户设备101最多支持1个天线同时执行发送。此时M＝3，要为三个接收天线即天线2、天线3和天线4，分别配置插损参数。当插损参数为插损值，天线2对应的插损值为ΔT RxSRS(1)、天线3对应的插损值为ΔT RxSRS(2)和天线4对应的插损值为ΔT RxSRS(3)。
在第三个示例中：
结合表3所示，在用户设备支持收发共用天线的数量最大为2，例如SRS天线切换能力对应2T4R、或者1T4R转2T4R、或者1T1R转1T2R转2T2R转2T4R、或者1T1R转1T2R转2T2R转1T4R转2T4R时，用户设备101支持2个收发共用天线(天线1和天线2)和2个接收天线(天线3和天线4)。
本示例中，SRS端口数为2，表明用户设备101最多支持2个天线同时执行发送，例如天线1和天线2可以同时收发。此时M＝2，要为两个接收天线即天线3和天线4，分别配置插损参数。当插损参数为插损值，二者的插损值可以相同或不同。

在第四个示例中：
当用户设备101具有更多的天线时，如支持1T8R，用户设备101可能上报更多的ΔT RxSRS。
例如，在SRS天线切换能力对应1T8R，且SRS端口数为1时，用户设备101可以上报7个ΔT RxSRS，以分别对应7个接收天线。此时，用户设备101在能力信息中可上报天线标识及其对应的插损参数。
再例如，在SRS天线切换能力对应1T8R，且SRS端口数为2时，用户设备101可以上报3个ΔT RxSRS，每个ΔT RxSRS对应一组接收天线，每组接收天线可包含两个天线。此时，用户设备101可在能力信息中上报天线的组标识以及每组对应的插损参数。
再例如，在SRS天线切换能力对应1T8R，且SRS端口数为4时，用户设备101可以上报1个ΔT RxSRS，该ΔT RxSRS适用四个接收天线。
本公开实施例中，用户设备101在某一频段上报多个插损参数的场景中，用户设备可以结合自身能力以及网络的配置信息，确定要上报插损参数的数量，从而该多个插损参数可以匹配至对应的天线。
本公开实施例提供了一种发送能力信息的方法，该方法被用户设备101执行。该方法包括步骤S401，具体的：
步骤S401，用户设备101向网络设备102发送能力信息，能力信息包括用户设备101在探测参考信号SRS天线切换场景下接收天线的插损参数。
其中，能力信息包括第一频段下对应的至少一个插损参数。
在一些可能的实施方式中，该至少一个插损参数可以对应不同的接收天线。
在一些可能的实施方式中，能力信息还包括至少一个插损参数对应的接收天线的标识。
在一个示例中，结合表3对应的示例，当接收天线对应不同的插损参数时，用户设备101上报能力信息时，可在能力信息中同步上报每个接收天线对应的标识。
在一些在可能的实施方式中，插损参数包括以下中的一项：插损值，插损值范围。
本公开实施例中，在多个接收天线分别对应插损参数的场景下，用户设备101可在能力信息中同步上报接收天线的标识。

在一些可能的实施方式中，网络设备101可以根据该能力信息进行下行信道估计，例如估计下行信道质量。
本公开实施例中，网络设备102通过用户设备101上报的能力信息，获知该用户设备101接收天线的插损参数，以便于网络设备基于该用户设备接收天线的插损参数进行更合理的处理，如进行更准确的信道估计。
本公开实施例提供了一种接收能力信息的方法，该方法被网络设备102执行。参照图7，图7是根据一示例性实施例示出的一种接收能力信息的方法，如图7所示，该方法包括步骤S701～S702，具体的：
步骤S701，网络设备102接收用户设备101发送的能力信息，能力信息包括用户设备101在探测参考信号SRS天线切换场景下接收天线的插损参数。
步骤S702，网络设备102根据能力信息，确定插损参数适用的第一部分接收天线。
在一些可能的实施方式中，网络设备102先确定能力信息中指示的插损参数。
在一示例中，能力信息中可以是直接包含插损值，则网络设备102对能力信息解调处理后即可确定插损参数。
在一示例中，能力信息可以间接指示插损参数，例如通过比特指示的方式。此时，网络设备102根据能力信息中N个比特的值，确定对应的插损参数。
该示例中，N可以大于或等于1。
该示例中，结合表1或者表2对应的示例，网络设备102根据N个比特的值，确定对应的插损值，或者插损值范围。
在一些可能的实施方式中，对于多天线的用户设备101，在天线轮发过程中，结合切换能力和SRS端口数的差异，可能其部分天线适用于能力信息中上报的插损参数。适用该插损参数的天线，在SRS天线切换场景中，插损参数才可用于补偿该天线对应的信道质量评估。
在一些可能的实施方式中，第一部分接收天线可能是用户设备101的全部接收天线，或者部分接收天线。
在一些可能的实施方式中，在能力信息还包括SRS天线切换能力的场景下，步骤S702可以包括如下步骤S702’，具体的：
步骤S702’，网络设备102根据SRS天线切换能力以及网络设备配置的SRS端口数，确定插损参数适用的第一部分接收天线。
该实施方式中，能力信息还包括：用户设备的SRS天线切换能力。例如，用户设备101支持1T2R、1T4R或者2T4R等等。
该实施方式中，能力信息可能包括多个频段分别对应的插损参数，或者包括某一频段(如第一频段)对应的插损参数。
在一些可能的实施方式中，能力信息包括多个频段中每个频段对应的插损参数。例如，用户设备101对于不同频段分别上报该频段对应的插损参数。
该实施方式中，步骤S702可以包括如下步骤S702-1，具体的：
步骤S702-1，在多个频段的任一频段下，确定任一频段对应的插损参数适用的第一部分接收天线。
该实施方式中，每个频段可对应上报一个插损参数。即，该示例中，网络设备102可确定任一频段中，适用该一个插损参数的第一部分接收天线。
该实施方式中，当每个频段上报一个以上的插损参数，实施方式可参照下述第一频段对应实施例的描述。
该实施方式中，网络设备102需要结合用户设备101的切换能力以及SRS端口数，确定适用插损参数的接收天线。
为便于理解本公开实施例，以下结合表3列举三个示例进行说明。
在第一个示例中：
结合表4所示，能力信息中包括多个频段中某一频段对应的插损值ΔT RxSRS。
在用户设备支持收发共用天线的数量最大为1，例如SRS天线切换能力对应1T2R或者1T1R转1T2R时，用户设备101支持1个收发共用天线(天线1)和1个接收天线(天线2)。
本示例中，SRS端口数为1，表明用户设备101最多支持1个天线同时执行发送。网络设备102即可确定该插损参数仅适用于该1个接收天线(天线2)。即本示例中，第一部分天线包括天线2。
在第二个示例中：
