进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、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 point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
相关技术中，在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收。通过多个天线实现多发多收，在不增加频谱资源和天 线发射功率的情况下，可以成倍的提高系统信道容量，并提高数据吞吐量和信噪比,从而提高系统性能并改善通信质量。
为了支持各种终端收发能力下能够通过信道，有效的获取到下行信息，通信系统中针对终端设置不同的天线切换配置。不同的天线切换配置对应不同的SRS。
在标准版本(R15或R16)中，支持网络设备侧通过信道互易获取下行信道信息，以提高下行数据传输性能。为了支持各种终端收发能力下，网络设备都能通过信道互易有效获取下行信息，设计了SRS参考信号。目前，在R15/R16中，定义的终端的收发能力可以分为收发天线数目相同(T＝R)以及收天线多于发天线(R>T)。其中，收发天线数目相同的终端收发能力主要有：一发一收(1T1R)、两发两收(2T2R)、四发四收(4T4R)。收天线多于发天线的终端收发能力主要有：一发两收(1T2R)、一发四收(1T4R)、两发四收(2T4R)。
在5G NR系统中，SRS资源的触发可以包括周期/半持续/非周期的SRS资源配置触发机制。周期/半持续/非周期的SRS资源配置触发机制不同。其中，周期的SRS(P-SRS)所有参数由高层信令配置，由高层信令进行配置后终端根据所配置的参数进行周期性发送。半持续的SRS(SP-SRS)所有参数也由高层信令配置，与周期探测参考信号(SRS)不同之处是，虽然相应参数已经被配置，但是终端在收到激活命令之前不能发送SRS。一旦被激活终端开始发送SRS，直到收到网络设备发送的去激活命令，停止发送SRS。SP-SRS的激活、去激活命令由MAC层发送也就是MAC CE命令。非周期的SRS资源(AP-SRS)触发通过下行控制信令(Downlink Control Information，DCI)中的SRS request来触发。
相关技术中，上行SRS可以是周期SRS、半持续SRS或非周期SRS。窄带或宽带，单端口或多端口。上行SRS参数由网络设备向终端配置，并包括端口数目、频域资源位置、时域资源位置、序列、序列循环偏移量等。在5G NR系统中，SRS资源在一个上行时隙的最多六个符号上映射，如图2所示，示出了时隙内SRS资源映射区域。
其中，网络设备为终端可以配置多个上行SRS资源集合，一个SRS资源集合包含一个或者多个SRS资源。一个SRS资源可以映射在N个连续OFDM符号上，N可以占用1，2，4个符号。
其中，对于不同的天线配置，SRS资源配置情况也各不相同：
(1)对于收发天线数相同(T＝R)终端，网络设备可以最多配置两个SRS资源集合，在一个SRS资源集合中只有一个SRS资源集合的端口数等于终端的发送天线数。两个SRS资源集合中一个SRS资源集合可以配置为周期，另一个SRS资源集合可以配置为非周期。
(2)对于一发两收(1T2R)能力的终端，网络设备可以最多配置两个SRS资源集合， 在一个SRS资源集合中有两个SRS资源，两个SRS资源中的每个SRS资源仅有一个端口。
(3)对于两发四收(2T4R)能力的终端，网络设备可以最多配置两个SRS资源集合，在一个SRS资源集合中有两个SRS资源，两个SRS资源中的每个SRS资源有两个端口。
(4)对于一发四收(1T4R)能力的终端，网络设备配置SRS资源需要特殊考虑。对于周期或半持续SRS资源最多只能配置一个SRS资源集合，SRS资源集合中有四个SRS资源，并且四个SRS资源各有一个端口。对于非周期SRS资源最多可以配置两个SRS资源集合、两个SRS资源集合里一共有四个SRS资源，而这四个SRS资源在两个时隙内发送且这四个SRS资源由不同的物理天线发送。两个SRS资源集合可以每个SRS资源集合各配置两个SRS资源，或一个SRS资源集合配置一个SRS资源，另一个SRS资源集合配置三个SRS资源，且每个SRS资源只有1端口。
相关技术中，支持终端进行天线能力上报。其中，在R15中，终端支持的天线能力为：T1R2,T1R4,T2R4,T1R4-T2R4,T1R1,T2R2,T4R4。在R16中，终端支持的天线能力为：T1R1-T1R2，T1R1-T1R2-T1R4，T1R1-T1R2-T2R2-T2R4，T1R1-T1R2-T2R2-T1R4-T2R4，T1R1-T2R2，T1R1-T2R2-T4R4。
在最新的标准版本(R17)中，定义终端可以在任意一个符号上发送SRS资源，SRS资源的长度也可以支持最大传输14个符号。进一步的，在R17的研究中，考虑终端的天线数有进一步增加的需求，因此会进一步增加天线数目。目前，指出最大6天线或者最大8天线。目前定义的典型的天线配置为{1T6R，1T8R，2T6R，2T8R，[4T6R]，4T8R}，如下表1所示：
表1：最多到8天线的SRS天线切换组合
Tx\Rx 6Rx 8Rx
1T 1T6R 1T8R
2T 2T6R 2T8R
4T 4T6R 4T8R
为了适用当前业务或者场景，终端可能需要改变天线配置，例如，当前终端有部分天线处于其他无线接入技术(Radio access technology，RAT)接收，或者某些天线在当前频段下的增益较低，或者终端当前有省电需求，或者这时从终端业务发送角度也需要考虑改变天线配置。例如从2T4R降低为1T4R或者2T2R。或者从2T2R改变为4T4R。终端改变天线配置时，需要使用不同的功能为“天线切换”的SRS资源配置用于下行信道状态信息(Channel State Information，CSI)的获取。
相关技术中，终端的天线配置是对应每个BWP的。通过无线资源控制(Radio Resource  Control，RRC)重配或者BWP切换实现天线配置的切换。但是这个切换主要通过业务变化由网络设备重新调度实现，无法根据终端的情况来触发，也就无法使网络设备满足终端的切换需求，无法更快更灵活的适应终端和业务要求支持天线配置的切换或者回退。
在R17中，支持终端上报天线切换配置能力。终端可以上报期望使用的天线切换配置。网络设备基于终端上报的天线切换配置，辅助调度天线切换配置为终端上报的天线切换配置。例如，终端上报期望的天线切换配置为：T1R1-T1R2-T1R4，网络设备在当前BWP的天线切换配置中配置为T1R1-T1R2-T1R4中的某个天线切换胚子，辅助终端进行天线切换配置改变。
相关技术中，终端经过测量或者事件触发，可以考虑天线切换配置的上报建议，并通过RRC或者媒体接入控制(Medium Access Control，MAC)控制单元(control element，CE)上报期望的天线切换配置。其中，终端通过RRC或者MAC-CE上报期望的天线切换配置可以采用如下方式：
1)终端期望的发送天线(端口)数目或者对应期望使用的发送天线的bitmap。例如，对于具有4个发送天线的终端，上报0011，则希望使用天线2和3，不使用天线0和1。
2)终端期望的接收天线(端口)数目或者对应期望使用的接收天线的bitmap。例如，对于具有4个接收天线的终端，上报0101，则希望使用天线1和3，不使用天线0和2。
3)终端期望的天线切换配置。例如，直接上报期望使用的nTmR的配置，或者上报该nTmR配置对应的索引(index)，或者上报该nTmR配置对应的指示信息。
上述进行天线切换配置的上报时，需要引入新的MAC-CE进行上报。本公开提供一种上报天线切换配置的方法，终端在满足触发通过MAC-CE上报终端期望的天线切换配置的触发条件下，上报终端期望的SRS天线切换配置。
图3是根据一示例性实施例示出的一种上报天线切换配置的方法的流程图，如图3所示，上报天线切换配置的方法用于终端中，包括以下步骤。
在步骤S11中，确定触发条件，该触发条件用于触发通过MAC-CE上报终端期望的天线切换配置。
在步骤S12中，响应于满足触发条件，通过MAC-CE上报终端期望的天线切换配置。
本公开中，用于触发通过MAC-CE上报终端期望的天线切换配置的触发条件可以是基于协议预定义的，也可以是基于网络信令配置的。例如，可以由网络设备通过网络信令为终端配置一项或多项触发条件。
本公开中，在满足通过MAC-CE上报终端期望的天线切换配置的触发条件情况下，终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开一种实施方式中，由定时器触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。本公开中为描述方便将该配置的用于触发终端通过MAC-CE向网络设备上报天线切换配置报告的定时器称为第一定时器。
本公开中可以配置第一定时器，以定时触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。即，通过第一定时器，控制终端周期性通过MAC-CE向网络设备上报终端期望的天线切换配置。换言之，本公开中通过第一定时器定时触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。其中，第一定时器用于控制天线切换配置的上报周期。
本公开另一种实施方式中，可以是在天线端口接收质量发生改变的情况下，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开中，天线端口接收质量发生改变，包括以下至少之一：
A：存在第一数量的天线端口的接收质量发生改变，且改变后的接收质量低于第一门限值。
B：存在第二数量的天线端口的接收质量与最近一次上报的天线端口接收质量不同，且二者之间的差值，大于第二门限值。
C：存在第三数量的天线端口的接收质量与天线端口接收质量最好的接收质量不同，且二者之间的差值，大于第三门限值。
一示例中，响应于当前有N个天线端口的接收质量改变,且该N个天线端口改变后的接收质量低于配置门限K1_threshold，通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，响应于当前有N个天线端口的接收质量相对最近一次上报的天线端口的接收质量改变，且接收质量相对最近一次上报的天线端口的接收质量变差，二者之间的差值超过配置门限K2_threshold，通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，响应于当前有N个天线端口的接收质量和接收质量最好的端口之间的接收质量差异超过一定的配置门限K3_threshold，通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，响应于当前有N个天线端口的接收质量改变,且该N个天线端口改变后的接收质量低于配置门限K1_threshold，且N个天线端口的接收质量和接收质量最好的端口之间的接收质量差异超过一定的配置门限K3_threshold，通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开中，上述涉及的第一数量、第二数量以及第三数量基于网络信令确定，或者基 于预定义规则确定。
其中，第一数量、第二数量以及第三数量可以相同，也可以不同。
本公开中，上述涉及的第一门限值、第二门限值以及第三门限值基于网络信令确定，或者基于预定义规则确定。
其中，第一门限值、第二门限值以及第三门限值可以相同，也可以不同。
本公开又一种实施方式中，可以是在终端基于省电需求关闭部分天线的情况下，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，响应于终端启动省电模式或其他省电需求，终端需要关闭部分接收天线或发送天线，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开又一种实施方式中，可以是在终端天线用途发生改变的情况下，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，响应于终端天线用途发生改变，通过MAC-CE向网络设备上报终端期望的天线切换配置。例如，对于NR\无线保真(Wireless Fidelity，WIFI)\蓝牙(BLUETOOTH)进行天线复用的情况，天线用途由NR转向WIFI或BLUETOOTH时，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开又一种实施方式中，可以是在终端天线损坏的情况下，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，响应于终端天线损坏，通过MAC-CE向网络设备上报终端期望的天线切换配置。例如，对于终端用户驻地设备(Customer premises equipment，CPE)等终端，响应于出现天线故障损坏，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开又一种实施方式中，响应于终端进行上行信道调度信息上报的冗余比特填充量大于天线切换配置报告对应的比特，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
一示例中，在通过冗余比特进行代替填充的方案中，如果匹配调度传输块所需的填充量大于天线切换配置报告，则可以通过插入天线切换配置报告，以利用净荷为调度提供有用信息。换言之，响应于匹配调度传输块所需的冗余比特填充量大于天线切换配置报告对应的比特，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开中，触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置的触发条件中，可以是包括以下至少一项：
A：通过第一定时器定时触发，第一定时器用于控制天线切换配置的上报周期；
B：天线端口接收质量发生改变；
C：终端基于省电需求关闭部分天线；
D：终端天线用途发生改变；
E：终端天线损坏；
F：终端进行上行信道调度信息上报的冗余比特填充量大于天线切换配置报告对应的比特。
例如，本公开实施例中，可以在天线端口接收质量发生改变的情况下，通过第一定时器定时触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
再例如，本公开实施例中们可以在终端天线损坏，并改变天线用途的情况下，通过第一定时器触发终端通过MAC-CE向网络设备上报终端期望的天线切换配置。
本公开上述涉及的触发条件可以是有多种组合形式，本公开对此不进行限定，也不再一一列举。
本公开中为了减少通过MAC-CE向网络设备上报天线切换配置的上行信令，可以配置终端通过MAC-CE上报天线切换配置的时间间隔。例如，本公开中可以配置终端通过MAC-CE上报天线切换配置的最小时间间隔，该最小时间间隔为相邻两次上报天线切换配置的时间间隔。终端基于最小时间间隔上报终端期望的天线切换配置。
可以理解的是，本公开中终端相邻两次上报天线切换配置的时间间隔应该大于或等于配置的最小时间间隔。
一种实施方式中，本公开中可以基于定时器配置终端相邻两次通过MAC-CE上报天线切换配置的最小时间间隔。本公开中将用于确定终端相邻两次通过MAC-CE上报天线切换配置的最小时间间隔的定时器，称为第二定时器。其中，该第二定时器可以理解为是禁止定时器。其中，禁止定时器可以理解为是在定时器停止之前，不允许终端通过MAC-CE上报天线切换配置。
本公开中，基于最小时间间隔上报终端期望的天线切换配置时，可以基于第二定时器上报终端期望的天线切换配置。其中，该第二定时器用于确定终端相邻两次通过MAC-CE上报天线切换配置的最小时间间隔。
本公开提供的上报天线切换配置的方法，基于终端的各类需求，对终端通过MAC-CE上报天线切换配置的触发条件进行定义，以在终端满足触发通过MAC-CE上报终端期望的天线切换配置的触发条件情况下，通过MAC-CE上报终端期望的天线切换配置。
基于相同的构思，本公开还提供一种应用于网络设备的上报天线切换配置的方法。
图4是根据一示例性实施例示出的一种上报天线切换配置的方法的流程图，如图4所示，上报天线切换配置的方法用于网络设备中，包括以下步骤。
在步骤S21中，响应于满足触发条件，通过MAC-CE接收终端上报的天线切换配置。
本公开中，上述涉及的触发条件用于触发终端通过MAC-CE上报终端期望的天线切换配置。
其中，用于触发终端通过MAC-CE上报终端期望的天线切换配置的触发条件可以是基于协议预定义的，也可以是网络设备确定并通过网络信令配置给终端的。

一种实施方式中，第一数量、第二数量以及第三数量基于网络信令确定，或者基于预定义规则确定。
其中，第一数量、第二数量以及第三数量可以相同，也可以不同。
本公开中，上述涉及的第一门限值、第二门限值以及第三门限值基于网络信令确定，或者基于预定义规则确定。
