相关申请的交叉引用
本申请主张在2022年6月15日在中国提交的中国专利申请号No.202210680784.1的优先权,其全部内容通过引用包含于此。
本申请属于通信技术领域,具体涉及一种天线能力变更方法、装置、终端及网络侧设备。
多卡终端(Multi-USIM,MUSIM)是指安装了不止一张通用用户识别模块(Universal Subscriber Identity Module,USIM)卡的终端。以双卡终端为例,为了支持双卡同时处于无线资源控制(Radio Resource Control,RRC)连接态进行信号的传输。目前包括两种方案:一种方案是用两套硬件或射频来实现,相当于两个完整的终端主板合在一起,放在同一个终端外壳中。这样的实现方式,能够支持两张USIM卡同时工作,但存在成本高、耗电量高、设备体积大等缺点。另一种方案是双卡可以共同使用终端的部分硬件或射频,这些硬件或射频根据双卡的实际需要在双卡的网络中变更。例如,当卡1在连接态,卡2在非连接态,终端的能力被卡1占用。若卡2将要建立或恢复RRC连接,需要将卡1的能力变更一部分到卡2,此时网络1会以终端之前上报的用户设备(User Equipment,UE)能力来配置或调度终端,从而导致终端会丢失网络1的数据或造成网络1资源浪费等后果。
综上,在MUSIM场景下,多卡终端在多张USIM卡间可以复用一些天线,来节省终端成本和减小体积。但是将卡1的部分天线切到卡2,卡1会存在以下问题:
问题1:如果在MUSIM天线变更中将卡1的载波1的多入多出(Multiple-In Multiple-Out,MIMO)能力全部变更到至卡2,那么变更后载波1没有可以用于传输的天线。
问题2:如果在MUSIM天线变更中将卡1的载波1的MIMO降阶,而载波1因为双卡频带干扰无法进行数据传输,此时载波1的剩余MIMO能力也无法使用。
上述问题导致多卡终端将部分天线从卡1切到卡2后,卡1的传输性能会收到影响。

需要说明的是,天线能力可以包括以下至少一项:射频链(RF chain)、发送链(Tx chain)、接收链(Rx chain)、发送(Tx)、接收(Rx)、MIMO层(MIMO layer)、接口(Port)、面板(Panel)、波束(Beam)。进一步地,天线能力可以是上行的和/或下行的。
本申请实施例中,终端向发生天线能力变更的第一USIM卡对应的网络侧设备发送天线能力变更的相关信息,使得网络侧设备能够基于终端上报的天线能力变更的相关信息配置或调度终端,从而降低多卡的天线能力变更对当前网络侧造成的性能影响,提升多卡终端的用户体验。
在本申请的至少一个实施例中,在所述天线能力变更的相关信息用于请求变更终端天线能力的情况下,所述天线能力变更的相关信息包括以下至少一项:

作为另一个可选实施例,上述天线能力变更信息可以为RRC消息或MAC CE。
示例一,终端通过天线能力变更请求来指示载波对的天线变更
步骤1,UE1向网络侧上报自己的MIMO能力。例如,指示自己在频带(Band)1、Band 2、Band 3分别支持2个下行多入多出层(2DL MIMO layer)。
步骤2:UE1被配置了3个载波,载波1、载波2、载波3的最大下行多入多出层(max DL MIMO layer)均为2;3个载波分别在band1,band2,band3。
UE2要在卡2发起RRC连接建立,多卡终端根据内部实现决定将UE1的某个载波(如载波1)的2个MIMO layer挪走。
步骤3:UE1向网络侧请求将载波1的MIMO layer降至0,基于MUSIM变更目的(for MUSIM switch purpose)。
步骤4:UE1发送天线能力变更请求,请求将载波3的2MIMO变更至载波1。所述天线能力变更请求包括以下域:
第一载波:3;
第二载波:1;
MIMO layer:2;
方向:下行。
步骤5:UE1接收天线能力变更信息,指示终端将载波3的2MIMIO变更至载波1。第一下行消息包括以下域:
载波A:3;
载波B:1;
MIMO layer:2。
在本申请的至少一个可选实施例中,在网络侧,由于网络侧的策略,比如是否有下行数据要发送给某个载波以及某个载波的负载情况,网络侧可能会有自己的偏好,从而网络侧可能会指示终端执行天线变更的载波对以及变更的天线数和终端上报的偏好不同。基于此,终端可以先向网络侧上报自己支持天线变更的载波对,在需要执行变更天线时,可以由终端和网络侧协商使用哪一个载波对,或者单独由网络侧决定。具体包括:在向网络侧设备发送所述第一信息之前,所述方法还包括:
向所述网络侧设备发送第一能力信息,所述第一能力信息用于指示所述终端执行所述天线能力变更的能力;其中,所述第一能力信息包括以下至少一项:

所述终端支持的变更天线数量,如MIMO层数;
所述终端执行天线能力变更期间被影响的频带或载波的信息,如频带列表或载波列表;
所述终端在支持天线能力变更的频带组合上支持的特性。
作为一个可选实施例,上述第一能力信息可以是RRC消息,例如UE能
力信息或UE辅助信息。
承接上例,在终端发送第一能力信息的情况下,所述方法还包括:
所述终端接收所述网络侧设备发送的至少一套天线变更配置信息;每套天线变更配置信息与一对候选载波对关联;其中,一套所述天线变更配置信息包括以下至少一项:
天线能力切出的载波的标识;
天线能力切入的载波的标识;
变更天线数量,如变更的MIMO层数。
作为一个可选实施例,在网络侧设备发送至少两套天线变更配置信息的情况下,所述方法还包括:
所述终端接收网络侧设备发送的第二信息,所述第二信息用于触发至少两套天线变更配置信息中的一套天线变更配置信息对应的天线变更。例如,网络侧设备使用RRC消息配置至少两套天线变更配置信息,再使用下行控制信息(Downlink Control Information,DCI)或MAC CE或基于定时器(timer-based)方式触发天线变更。
可选的,在接收第二信息之前,所述终端还向网络侧请求触发天线变更,然后接收网络侧发送的第二信息。
作为另一个可选实施例,在网络侧设备发送一套天线变更配置信息的情况下,所述一套天线变更配置信息还用于触发对应的天线变更。例如RRC消息中仅配置一套的情况下直接激活这套配置,也即直接触发这对载波的天线变更。此外,网络侧也可以直接通过DCI或者MAC CE来指示在一对载波间进行天线变更。
示例二,终端发送第一能力信息,网络预配置天线变更的配置,使用低层信令来触发变更
步骤1:UE1向网络侧上报自己的MIMO能力。例如,指示自己在Band1、Band2、Band3支持2DL MIMO layer。

在该BC上,指示终端支持在{band1,band2}、{band1,band3}这两个band pair上进行下行天线变更;
指示在支持的band pair上,终端支持或期望变更的天线数量,如1RX MIMO、1DL MIMO等;
指示终端执行下行天线变更所需要的时间,所述时间可以是基于频带对(per band pair)的,也可以是基于频带组合(per BC)的;
步骤3:UE1被配置了3个载波,载波1、载波2、载波3的max DL MIMO layer为2,3个载波分别在band1,band2,band3。
步骤4:UE1接收网络侧发送的天线变更配置信息;例如,指示2个候选载波对(pair):
Pair 1:将载波1的1MIMO变更至载波2;
Pair 2:将载波1的1MIMO变更至载波3。
UE2要在卡2发起RRC连接建立,多卡终端根据内部实现决定将UE1的某个载波(如载波1)的1个MIMO layer挪走。
步骤5:UE1向网络侧发送第一请求,用于请求执行天线能力变更,可以是RRC或者MAC CE或者DCI信令。
步骤6:UE1接收第一MAC CE,若步骤4中网络侧配置了多对候选pair,则所述第一MAC CE指示哪一对载波对触发了天线变更(如pair 1)。若步骤4中仅配置了一个候选pair,则第一MAC CE直接触发这一对载波的天线变更。
目前终端可以在出于过热(overheating)或节能(power saving)的目的向网络侧发送UE辅助信息,其中指示自己期望的max MIMO layer数,从而达到缓解过热和省电效果。UE辅助信息只能指示终端想要在所有的载波上减少的MIMO layer,无法指示自己想要仅在某个载波上进行MIMO layer降阶。要想实现天线能力在一对载波间变更,本申请实施例对UE辅助信息消息进行改进,具体如下:所述第一信息还包括终端辅助信息,所述终端辅助信息包括以下至少一项:
在第三载波上终端期望降低的多入多出MIMO层数;

步骤2:UE1被配置了3个载波,载波1、载波2、载波3的max DL MIMO layer为2,3个载波分别在Band1,Band2,Band 3。
UE2要在卡2发起RRC连接建立,多卡终端根据内部实现决定将UE1的某个载波(如载波1)的1个MIMO layer挪走。
步骤3:UE1向网络侧请求将载波1的MIMO layer降至0 for MUSIM switch purpose。
步骤4:UE1向网络侧发送第一UAI,其中指示载波1的DL MIMO layer增加为2,载波2的DL MIMO layer将为0。
步骤5:UE1接收RRC重配消息,将载波1的max MIMO layer配置为2,将载波2的max MIMO layer配置为0。
在本申请的至少一个实施例中,由于多卡终端从卡1切走一些能力到卡2的时候,会有调整终端在卡1的不同band/不同载波上的能力分配情况的需求,那么终端可以在上报UE能力时上报2套UE能力,具体如下:所述第一信息还包括终端的第二能力信息,所述第二能力信息包括:

承接上例,所述方法还包括:
所述终端接收所述网络侧设备发送的第四信息,所述第四信息用于指示终端变更所述目标载波的状态为第一状态;其中,所述第一状态包括以下至少一项:释放状态、激活状态、去激活状态、休眠状态。
