具体实施方式
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。
本公开实施例提供的天线切换配置的切换方法可应用于图1所示的无线通信系统中。参阅图1所示,该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备相连接,并进行数据传输。
可以理解的是,图1所示的无线通信系统仅是进行示意性说明,无线通信系统中还可包括其它网络设备,例如还可以包括核心网设备、无线中继设备和无线回传设备等,在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。
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,采用MIMO技术以提高数据传输速率,并提高数据吞吐量和信噪比。MIMO是指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,提高数据吞吐量和信噪比,从而提高系统性能改善通信质量。它能充分利用空间资源,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。
MIMO技术正越来越多地被应用于多种高数据速率技术,包括WiFi,4G长期演进(Long Term Evolution,LTE)以及5G NR。MIMO系统就是多个信号流在空中的并行传输。在发射端输入的数据流变成几路并行的符号流,分别从Nt个天线同时发射出去;接收端从Nr个接收天线将信号接收下来,恢复原始信号,如图2所示。
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。R15/16定义的终端的天线切换能力可以分为接收天线数量和发射天线数量相同(即,T=R),以及接收天线多于发射天线(即,R>T)。相关技术中,目前协议支持的T=R的情况,终端天线切换能力主要有一发一收(1T1R)、两发两收(2T2R)、四发四收(4T4R)。R>T的情况,即接收天线多于发射天线主要有几种情况:一发两收(1T2R)、一发四收(1T4R)、两发四收(2T4R)。
其中,R15中终端支持的天线切换能力为:1T2R,1T4R,2T4R,1T4R-2T4R,1T1R,2T2R,4T4R。
R16中终端支持的天线切换能力为:1T1R-1T2R,1T1R-1T2R-1T4R,1T1R-1T2R-2T2R-2T4R,1T1R-1T2R-2T2R-1T4R-2T4R,1T1R-2T2R,1T1R-2T2R-4T4R。
目前在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到最大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
其中,4T6R是否支持目前待定,后续从标准角度大概率会支持。
不同的天线切换配置对应不同的探测参考信号资源配置,当前协议中支持的主要天线切换配置,对应的,探测参考信号(Sounding Reference Signal,SRS)资源配置有如下几种情况:
(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,在一个集合中只有一个SRS资源其中端口数等于终端的发送天线数。两个SRS资源集合中一个可以配置为周期,另一个可以配置为非周期。
(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,在一个集合中有两个SRS资源、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,在一个集合中有两个SRS资源、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,周期或半持续SRS资源最多只能配置一个资源集合,其中有4个SRS资源各有1个端口;为非周期SRS资源最多可以配置2个SRS资源集合、两个SRS资源集合里一共有4个SRS资源,而这4个资源在两个slot内发送且这4个资源由不同的物理天线发送。两个资源集合可以每个集合各配置2个资源,或一个集合1个另一个集合3个资源,每个资源只有1端口。
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。
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探测参考信号(SRS)。一旦被激活终端开始发送探测参考信号(SRS)直到收到网络侧发的去激活命令。半持续探测参考信号(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,表2是具体的触发信令。
表2
Figure PCTCN2021075650-appb-000001
相关技术中,上行SRS可以是周期、半持续SRS或非周期SRS。窄带或宽带,单端口或多端口。上行SRS参数由网络向终端可以配置包括端口数目、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在一个上行时隙的最多六个符号上映射,如图3所示,示出了时隙内SRS映射区域。
其中,网络设备为终端可以配置多个上行SRS集合,一个资源集合包含一个或者多个SRS资源。一个SRS资源可以在N个连续OFDM符号上,N可以占用1,2,4个符号。
R15/16NR系统中支持gNB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gNB也能通过信道互易有效获取下行信息,NR系统特别设计了SRS参考信号。
进一步的,为了适用当前业务或者场景,终端可能需要改变天线配置,例如从2T4R降低为1T4R或者2T2R,或者从2T2R改变为4T4R的情况,这时就需要进行天线切换配置的切换。
如果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,或者从终端业务发送角度也需要考虑改变天线配置。
当前的天线配置为per BWP,可以通过无线资源控制(Radio Resource Control,RRC)重配或者BWP切换实现,但是这个切换主要通过业务变化由网络侧重新调度实现,无法根据其他终端侧的情况来触发,无法使网络满足UE侧的切换需求,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。目前机制同样也无法为BWP上的快速动态切换天线切换配置方法提供更好的测量上报支持。
有鉴于此,本公开实施例中提供一种天线切换配置的切换方法,终端根据网络配置上报天线切换配置需求信息,通过该天线切换配置需求信息指示终端期望使用的天线切换配置信息。网络设备接收终端发送的天线切换配置需求信息,基于天线切换配置需求信息,辅助进行天线切换配置的切换。故,本公开实施例提供的天线切换配置的切换方法,网络设备可以基于终端的需求较为准确并快速的实现天线切换配置的切换,辅助终端进行天线切换配置的切换,可以节约发送功率或接收功率,使系统资源可以优化使用。
图4是根据一示例性实施例示出的一种天线切换配置的切换方法的流程图,如图4所示,天线切换配置的切换方法用于终端中,包括以下步骤。
在步骤S11中,响应于确定需要进行天线切换配置的切换,根据网络配置上报天线切换配置需求信息。
其中,本公开实施例中,天线切换配置需求信息用于指示终端期望使用的天线切换配置信息。
本公开实施例中,终端设置有至少两个候选天线切换配置,且能够从所述至少两个候选天线切换配置中确定一个候选天线切换配置,或是能够从一个候选天线切换配置切换到另一个候选天线切换配置。
本公开实施例提供的天线切换配置的切换方法中,终端可以支持多个天线切换配置,例如1T1R_2T2R_4T4R。终端可以进行天线切换配置的切换。网络设备可以在当前BWP将天线切换配置切换为某个天线切换配置。其中,终端经过测量或者事件触发可以确定需要进行天线切换配置的切换,即希望改变天线切换配置。响应于终端确定需要进行天线切换配置的切换,根据网络配置上报天线切换配置需求信息,天线切换配置需求信息用于指 示终端期望使用的天线切换配置信息。故,本公开实施例提供的天线切换配置的切换方法可以基于终端的需求,较为准确并快速的实现天线切换配置的切换,并可以节约发送功率或接收功率,使系统资源可以优化使用。
本公开实施例提供的天线切换配置的切换方法中,天线切换配置需求信息有时也可以理解为是终端期望改变天线切换配置所上报的建议值,或者也可以理解为是终端期望改变天线切换配置所上报的上报量。本公开实施例对于指示终端期望使用的天线切换配置信息所向网络设备上报的信息的名称不作限定,以上涉及的名称有时会交换使用,本领域技术人员应理解其含义的一致性。

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比特位图(bitmap),如4个发送天线的终端,如果按照比特位图上报0011,则代表希望使用天线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,如4个接收天线的终端,如果按照比特位图上报0101,则代表希望使用天线1和3,不使用天线0和2;
3)终端期望的天线切换配置,如直接上报期望使用的nTmR的配置或者该配置对应的index或者其指示信息,比如终端支持3种天线切换配置的切换能力,分别为:1T1R_1T2R_2T2R。由高层编号或者预定义1T1R对应编号0,1T2R对应编号1,2T2R对 应编号2,那么当终端上报1则对应希望选择配置1T2R,或者终端上报对应的比特位图bitmap,如010则对应配置1T2R。
可以理解的是,本公开实施例提供的天线切换配置的切换方法中,天线切换配置需求信息除包括上述实施例涉及的信息以外,还可以包括其他信息。
进一步可以理解的是,天线切换配置需求信息可以是预定义的或者高层通知的定义方式。例如,终端期望的天线切换配置是预定义的或者高层通知的。
本公开实施例提供的天线切换配置的切换方法中,天线切换配置需求信息中包括多种天线切换配置需求信息时,终端可以对多种天线切换配置需求信息进行优先级排序,基于排序后的优先级进行天线切换配置的切换。例如,终端如果配置上报多个上报量时,可以根据对以上上报量进行优先级的排序;其中终端可以自行确定优先级,也可以根据相关通信协议确定优先级,还可以根据基站配置确定优先级。
本公开实施例提供的天线切换配置的切换方法中,终端经过测量或者事件触发可以确定需要进行天线切换配置的切换,即希望改变天线切换配置。
一示例中,响应于满足如下条件之一或组合,终端确定需要进行天线切换配置的切换:
