为便于理解本申请实施例的技术方案,以下对本申请实施例涉及到的相关技术进行说明。

多入多出(Multiple-Input Multiple-Output,MIMO)传输
MIMO已经被广泛地用于无线通信系统中,例如3G,4G(LTE),5G(NR),WiFi。利用MIMO技术,可以获得以下多种形式的增益:
·空间分集增益
·波束赋型增益(预编码增益)
·空间复用增益
为了获得波束赋型增益(也叫预编码增益)或空间复用增益,发送端需要确定一个波束赋型矩阵(或者预编码矩阵)来进行信号传输。为了描述简单,后续的“预编码”和“波束赋型”将会混合使用,不再做区分,即使用其中任何一个术语,描述内容都可以应用于“预编码”和“波束赋型”的场景。
预编码矩阵的确定,往往需要基于对应的传输信道信息。可选的,在这一基础上,预编码矩阵的确定还可以基于多用户MIMO配对用户对应的信道信息、干扰信息等。因此针对终端A的预编码矩阵的确定,一个基本需求就是要获得终端A对应的传输信道的某些形式的信道信息。
在实际系统中,为了终端A对应的传输信道的信道信息,可以有以下两大类方法:
1.反馈方法:基站B发送参考信息X(例如信道状态信息参考信号(CSI-RS)),终端A根据参考信号X,测量获得对应下行信道的信息,然后确定反馈信息。基站B根据终端A的反馈信息,确定对应的预编码矩阵,并给终端A发送物理下行共享信道(Physical Downlink Shared Channel,PDSCH)或者物理下行控制信道(Physical Downlink Control Channel,PDCCH),或其他下行信道或参考信号。其中,反馈信息可以包括以下一些形式(可以是部分):
a.秩指示信息(Rank Indication,RI),RI包括rank信息。
b.信道质量指示信息(Channel Quality Indicator,CQI),CQI包括调制与编码策略(Modulation and Coding Scheme,MCS)的相关信息。
c.预编码矩阵指示信息(Precoding Matrix Indicator,PMI),PMI包括码本信息。
2.基于信道互异性的方法:终端A根据基站B的配置信息发送SRS信息,基站B根据接收到的SRS信息测量得到对应的上行信道,根据上下行信道的互异性,基站B可以确定终端A对应的预编码矩阵用于发送PDSCH或PDCCH,或其他下行信道或参考信号。
需要说明的是,反馈方法适用于时分双工(Time Division Duplexing,TDD)系统和频分双工(Frequency Division Duplexing,FDD)系统;而基于信道互异性的方法主要用于TDD系统,也可以用于带有部分互异性的FDD系统。
Figure PCTCN2019098251-appb-000002
天线切换
从上面的技术方案可以看到,基于信道互异性的方法需要让终端A发送SRS信号。在NR中,这类SRS信号对应的SRS资源组(SRS resource set)的配置如下:
SRS-ResourceSet中的用途参数(usage)设为天线切换(antennaSwitching)。
这类SRS信号进行探测(sounding)的过程又被称为针对DL CSI acquisition的UE探测过程(UE sounding procedure for DL CSI acquisition),天线切换也可以称为SRS发射端口切换(SRS Tx port switching),SRS切换(SRS switching)或者SRS发送切换(SRS Tx switching)。
对于典型的终端(如智能手机)而言,接收天线数目往往会大于发送天线数目,或者说接收通道数目往往会大于发送通道数目,例如图2-1中,终端A有两个天线,其中,终端A支持1个发射通道和2个接收通道,即每个时刻,只有1个天线用于发送(连接所述的1个发射通道),可以有2个天线用于接收。因此如果终端A发送一次SRS(1个发射通道,对应的SRS资源是1个SRS端口),基站B只能获得8*1的信道信息,即有一半的信道对应的信道信息不知道,从而会影响获得更佳的预编码性能。
需要说明的是,上述描述是假设基站B通过预编码矩阵给终端A传输 信息,本申请实施例的技术方案也可以用于终端B通过预编码矩阵给终端A传输信息,两个终端之间的通信例如是设备到设备(Device to Device,D2D)通信,或者车联网(vehicle to X,V2X)通信,或者侧行链路(sidelink)通信。
为了解决上述问题,网络可以配置2个SRS资源,每个SRS资源具有1个SRS端口,两个SRS资源分别从2个天线发射,且两个SRS资源从不同时刻传输,例如在时刻T0上从天线0传输SRS资源0对应的SRS信号(此时发射通道切换到天线0上),在时刻T1上从天线1传输SRS资源1对应的SRS信号(此时发射通道切换到天线1上)。这样通过2次SRS发送,可以让基站B获得8*2的信道信息。上述2个SRS资源会被配置在同一个SRS资源组中,其中对应的usage也会被设为“antennaSwitching”。
终端A是否支持“antennaSwitching”(等效的,称为是否支持SRS Tx port switching),以及支持何种类型的天线切换,可以有不同的实现。因此通过UE能力(UE capability)来进行上报。NR对应的UE能力上报有以下这些:t1r2,t1r4,t2r4,t1r4-t2r4,t1r1,t2r2,t4r4,notSupported,其中('t1r2'for1T2R,'t2r4'for 2T4R,'t1r4'for 1T4R,'t1r4-t2r4'for 1T4R/2T4R,'t1r1'for1T1R,'t2r2'for 2T2R,or't4r4'for 4T4R)。各个能力对应的描述如下:
·对于1T2R:可以配置0个或1个或者2个(最多2个)SRS资源组,这两个SRS资源组对应的资源类型(resourceType)配置不同值,即可以是非周期(aperiodic)、半持续(semiPersistent)、周期(periodic)。后续配置2个SRS资源组时,如不作额外说明,则都是类似情况。每个SRS资源组里面含有2个SRS资源,每个SRS资源具有1个SRS端口,这两个SRS资源从不同的符号(symbol)上传输,并且同一个SRS资源组中的两个SRS资源对应不同的天线端口(antenna port)。
·对于2T4R:可以配置0个或1个或者2个SRS资源组。每个SRS资源组里面含有2个SRS资源,每个SRS资源具有2个SRS端口,两个SRS资源从不同的符号(symbol)上传输,并且同一个SRS资源组中的第二个SRS资源的SRS端口对对应的天线端口对与第一个SRS资源的SRS端口对对应的天线端口对不同。
·对于1T4R:可以配置0个或者1个SRS资源组(可以是周期性或者半持续)。每个SRS资源组中含有4个SRS资源,每个SRS资源具有1个SRS端口,不同的SRS资源从不同的符号上传输,并且不同的SRS资源对应不同的天线端口。
·对于1T4R:可以配置0个或者2个SRS资源组(都配置为非周期)。2个SRS资源组中总共有4个SRS资源,每个SRS资源具有1个SRS端口,4个SRS资源从两个不同的时隙(slot)的不同的符号上传输。4个SRS资源对应不同的天线端口。4个SRS资源可以是每个SRS资源组含有2个SRS资源,或者可以是1个SRS资源组含有3个SRS资源,另一个SRS资源组 含有1个SRS资源。这两个SRS资源组对应的RRC配置的功率参数相同,同时高层参数aperiodicSRS-ResourceTrigger相同,但是参数slotOffSRS资源组不同。
·对于1T=1R,或者2T=2R,或者4T=4R:可以配置0个或1个或2个SRS资源组,每个SRS资源组包含1个SRS资源,SRS资源对应的SRS端口分别为1,2或4。
如果UE上报支持't1r4-t2r4,所有SRS资源组里面的SRS资源都必须配置相同的SRS端口(即1或2个SRS端口)。
终端数据传输往往是突发的,即有的时候数据量特别大,有的时候数据流很小,甚至只需要维持基本连接,这时候,不需要很大的传输能力,可以通过关闭部分上行发射通道,来降低终端功耗,从而改善用户体验。
在天线切换中,如果终端上报支持't1r4-t2r4'(即支持1T4R/2T4R),当对数据速率要求低的场景时,网络可以配置终端只发送具有1个SRS口的SRS资源用于天线切换,这时候终端可以关闭一个上行发射通道,从而可以降低功耗,改善用户体验。
另外一种典型的终端实现如图2-2所示,终端A支持2个发射通道(即对应2个功放(Power Amplifier,PA))。如果终端进行2T4R时,每个PA(即对应的每个发送通道)在两个天线之间切换。如果数据速率要求低的场景时,终端实际上可以关闭一个PA(即关闭一个发射通道),只保留1个发射通道,可以有效降低功耗,改善用户性能。但是根据前面描述的技术方案,网络侧不支持这么配置,具体地,如果终端支持2T4R,网络侧配置的SRS资源必须具有2个SRS端口,不能具有1个SRS端口,因此终端就无法实现只保留1个发射通道的功能,这对于终端功耗、以及用户体验不利。为此,提出了本申请实施例的以下技术方案。
