应当理解，在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。
如在本申请说明书和所附权利要求书中所使用的那样，术语“如果”可以依据上下文被解释为“当...时”或“一旦”或“响应于确定”或“响应于检测到”。
另外，在本申请说明书和所附权利要求书的描述中，术语“第一”、“第二”、“第三”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
在本申请说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
图1示出了一种本申请提供的天线选择方法的应用场景示意图，参考图1，场景中包括电子设备11、电子设备11上包括多根天线，例如，可以包括天线一111、天线二112、天线三113以及天线四114。场景中还包括网络设备12，电子设备11通过天线与网络设备12保持连接态。即，电子设备11为用户设备(User Equipment，UE)，网络设备12则为基站，例如可以是gNB或eNB。
由于UE上存在多根天线，因此需要选择其中最优天线进行通信，最优天线在通信时的通信质量最好。现有技术中，是通过配置与UE天线数量相同的多套上行无码表(noncoodbook，Non-CB)SRS资源，并依次在UE的每根天线上通过对应的Non-CB SRS资源，向基站轮发SRS，基站在接收到SRS后，根据天线对应的Non-CB SRS资源测量该天线的上行通信质量。同时，基站还会配置与UE天线数量相同的多套AS SRS资源，并通过AS SRS资源测量SRS的下行通信质量。最后，基站根据每根天线的上行通信质量、下行通信质量计算确定最优天线，并通知UE切换至最优天线。
或者，参考图2，图2示出了另一种本申请提供的天线选择方法的应用场景示意 图，在图2中，可以同时通过两根天线向基站发送SRS，由于Non-CB SRS资源和AS SRS资源进各自仅支持同时发送一个SRS，因此，为了同时发送两个SRS，则需要同时使用Non-CB SRS资源和AS SRS资源进行发送。
但是，部分UE在发送SRS时，不会考虑电磁波吸收比值(Specific Absorption Rate，SAR)。在确定最优天线后，通过天线发送上行物理共享信道(Physical Uplink Shared Channel，PUSCH)数据时，若天线的SAR大于规定的限值，则会对天线进行降SAR操作，降SAR后的天线通信质量可能并不是最优天线，因此，会导致并未在通信质量最优的天线上进行通信。
为此，本申请提供了一种应用于电子设备的天线选择方法，电子设备包括多根天线，该方法包括：依次通过每个天线，在不同的时频资源上向网络设备发送AS SRS和天线的标识信息。接收来自网络设备发送的天线选择消息，天线选择信息包括第一天线的标识消息以及其余每根天线相对于第一天线的信号质量增益。根据标识信息，获取第一天线的信号质量修正增益。当每个天线的信号质量增益均大于信号质量修正增益时，通过第一天线进行通信。
本申请还提供了一种应用于网络设备的天线选择方法，该方法包括：接收来自电子设备的多根AS SRS和每个AS SRS对应天线的标识信息。根据多个AS SRS的上行信号质量确定第一天线，第一天线对应的AS SRS的上行信号质量为接收到的多个AS SRS的上行信号质量中最好的。获取其余每根天线相对于第一天线的信号质量增益，信号质量增益是通过其余每根天线对应的AS SRS与第一天线的AS SRS计算得到的。向电子设备发送天线选择消息，天线选择信息包括第一天线的标识消息以及其余每根天线相对于第一天线的信号质量增益。
在本申请中，通过依次通过每个天线，在不同的时频资源上向网络设备发送AS SRS，并接收网络设备返回的第一天线的标识消息以及其余每根天线相对于第一天线的信号质量增益。最后根据第一天线的信号质量修正增益以及其余每根天线相对于第一天线的信号质量增益，确定是否使用第一天线进行通信。由于第一天线是网络设备测量得到的最优天线，根据最优天线的信号质量修正增益和其余每根天线相对于最优的信号质量增益确定是否使用网络设备测量得到的最优天线进行通信，可以更加准确地选择通信质量最好的天线并用于通信。
同时，由于使用AS SRS测量天线的上行信号质量，可以无需配置Non-CB SRS，或者只需配置一个Non-CB SRS以用于同时测量两根天线的情况，有效减少了基站的SRS资源占用，解决了基站的SRS资源不足的问题。

S301、电子设备的L3与网络设备的L3进行交互，网络设备获取电子设备的天线选择能力，电子设备接收网络设备配置的AS SRS资源。
一些实施方式中，天线选择能力包括天线数量、每根天线的标识信息以及是否支持闭环天线选择。例如，天线数量可以为4根，4个天线的标识信息可以分别为port0、port1、port2和port3。其中，闭环天线选择指的是能够发送用于天线选择的测量信号，并根据接收到的天线选择消息切换用于通信的天线。天线选择能力还包括发送天线选择(Transmit Antenna Selection，TAS)技术，该技术通过获取每根天线的下行能量，然后将每根下行能量中的主集能量与分集能量相减，得到下行能量差值。当下行能量差值大于预设的门限阈值时，确定当前测量的天线为最优天线。最后，检测当前用于通信的天线是否为最优天线，若是，则记录下行最优天线的标识信息。若不是，则将当前测量的天线用于通信，然后记录下行最优天线的标识信息。
需要说明的是，AS SRS资源为时域上的SRS资源。在时域上，SRS可占用普通上行子帧或特殊子帧的最后一个符号。在时分双工(Time Division Duplexing，TDD)系统中，SRS可以通过上行导频时隙(Uplink Pilot Time Slot,UpPTS)中的一个或两个单载波频分多址(Single-carrierfrequency division multiple access，SC-FDMA)符号传输。另外，SRS的传输周期(Tsks)可以从以单位为毫秒ms的时间集合{2，5，10，20，40，80，160，320}中选择。SRS资源包括一个确定的SC-FDMA和一个确定的传输周期。
一些实施方式中，网络设备还可以根据实际需求，为电子设备配置Non-CB SRS资源或者CB SRS资源。Non-CB SRS资源或者CB SRS资源与AS SRS资源类似，在此不做赘述。
一些实施方式中，网络设备可以根据电子设备天线的数量，配置对应数量的AS SRS资源。例如，若天线数量为4根，则可以为每个天线配置一个对应的AS SRS资源，即4套AS SRS资源。
S302、网络设备的L3获取电子设备配置的AS SRS的资源并上报给网络设备的L1。
S303、电子设备的L1依次通过每个天线，在不同的时频资源上发送AS SRS信号。
S304、网络设备的L1根据配置的AS SRS资源，测量每个AS SRS的上行信号质量。
一些实施方式中，假设电子设备的L1包括四根天线，每根天线配置了对应的AS SRS资源，四根天线依次通过对应的AS SRS资源发送AS SRS。网络设备的L1在接收到L3发送的配置给电子声的AS SRS资源后，在每个AS SRS资源上测量AS SRS的上行信号。当电子设备的四根天线轮发一遍后，网络设备即可测量到4个AS SRS的上行信号质量。
测量AS SRS的上行信号质量可以通过测量AS SRS的参考信号接收功率(Reference Signal Receiving Power，RSRP)或信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)来表示。
作为示例，当通过RSRP表示上行的信号质量时，RSRP越大表示上行信号质量越好。RSRP的单位是dBm。例如，参考S301中天线的示例，若port1的RSRP为-55dBm、port2的RSRP为-90dBm、port3的RSRP为-77dBm、port4的RSRP为-104dBm，则por1的上行信号质量最好，其次为port3，然后是port2，最次的为port4。
当通过SINR表示上行的信号质量时，SINR越大表示上行信号质量越好。SINR可基于RSRP计算获得，计算SINR可参照以下公式：
Figure PCTCN2021140163-appb-000001
其中，干扰功率(I)为网络设备接收到的AS SRS信号所占的资源块(Resource Element，RE)上接收到的邻小区的功率之和，噪声功率(N)为底噪，N的数值与具体测量带宽和接收机噪声系数有关。
S305、网络设备的L1将每个AS SRS的上行信号质量的测量结果发送给网络设备的L2。
S306、网络设备的L2确定第一天线，以及其余天线相对于第一天线的增益。
一些实施方式中，网络设备的L2可以将RSRP最大的天线确定为第一天线。或者，将SINR最大的天线确定为第一天线。
还有一种实施方式中，网络设备的L2可以根据RSRP，以及该RSRP对应天线的AS SRS发射功率，计算等效链路损耗(PathLoss)，将等效链路损耗最低的天线作为第一天线。例如，等效链路损耗可以为参考信号的信号功率即对应天线的AS SRS的RSRP之差，其中，参考信号的信号功率可从网络设备的系统消息中获取。
S307、网络设备的L2向网络设备的L3上报第一天线的标识信息，以及其余天线相对于第一天线的增益。
一些实施方式中，可以将其余每根天线的RSRP与第一天线的RSRP之差，作为该天线相对于第一天线的增益。或者，还可以将其余每根天线的SINR与第一天线的SINR之差，作为该天线相对于第一天线的增益。增益的算法在本申请中不做限制。
S308、网络设备的L3通过RRC消息向电子设备的L3发送第一天线的标识信息，以及其余天线相对于第一天线的增益。
S309、电子设备的L3根据标识信息，获取第一天线的信号质量修正增益。
一些实施方式中，信号质量修正增益可以为降SAR值，每根天线对应一个预设 的降SAR值，可根据天线的标识信息，从天线的属性信息中获取该天线对应的降SAR值。其中，天线的属性信息是制造电子设备时确定的。例如，天线数量可以为4根，4个天线的标识信息可以分别为port0、port1、port2和port3。port0、port1、port2和port3的降SAR值分别为2dB、5dB、6dB和7dB。
S310、电子设备的L3判断是否每个天线的信号质量增益均大于信号质量修正增益，若是，则执行S311，若否，则执行S312。
一些实施方式中，参考S309的示例，若port0对应的天线为第一天线，则port1、port2和port3相对于port0的增益可以分别为2dB、4dB和3dB。通过降SAR值修正后，port0、port1、port2和port3的综合增益可分别为-2dB(0dB-2dB)、-3dB(2dB-5dB)、-2dB(4dB-6dB)和-4dB(3dB-7dB)。port0的综合增益最大，因此执行S311。或者，若port0对应的天线为第一天线，则port1、port2和port3相对于port0的增益可以分别为2dB、4dB和6dB。通过降SAR值修正后，port0、port1、port2和port3的综合增益可分别为-2dB(0dB-2dB)、-3dB(2dB-5dB)、-2dB(4dB-6dB)和-1dB(6dB-7dB)。port3的综合增益大于port0，因此执行S312。
S311、电子设备的L1切换至第一天线进行通信。
一些实施方式中，若每个天线的信号质量增益均大于降SAR值，则表明当前的第一天线在降SAR之后，其通信质量依然优于其余天线。即确定第一天线为当前场景下的最优天线，可以通过第一天线进行通信。
S312、电子设备的L3通过TAS确定第二天线。
S313、电子设备的L1切换至第二天线进行通信。
另一些实施方式中，若每个天线的信号质量增益中存在小于降SAR值的，则表明当前的第一天线在降SAR之后，其通信质量并非最优。因此，需要通过TAS的方式重新选择最优天线(即第二天线)，然后通过第二天线进行通信。
在上述实施例中，网络设备通过RRC消息向电子设备通知最优天线以及其余天线相对于最优天线的选择结果。
在一些实施方式中，参考图6，网络设备还可以通过DCI消息向电子设备发送通知，以实现本申请提供的天线选择方法，该方法包括：
