具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示例性实施例提供的通信系统的框图,该通信系统可以包括:接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站,所述基站是一种部署在接入网中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如在LTE系统中,称为eNodeB或者eNB;在5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“基站”这一描述可能会变化。为方便本公开实施例中的描述,上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备,移动台(Mobile Station,MS),终端(terminal device)等等。为方便描述,上面提到的设备统称为终端设备。网络设备120与终端设备14之间通过某种空口技术互相通信,例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯 (Global System of Mobile Communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)系统、先进的长期演进(Advanced long Term Evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum,LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),车辆间(Vehicle to Vehicle,V2V)通信以及车联网(Vehicle to Everything,V2X)系统等。本公开实施例也可以应用于这些通信系统。
图2示出了本公开一个示例性实施例提供的PUSCH上行发送的示意图。
终端设备210处于服务小区(serving cell)之中,也处于邻小区(neighboring cell)之中。
终端设备210设置有至少一个天线面板。不同的天线面板的朝向可不同,从而可以收发不同传输方向的波束,从而实现多空间分集。如图2所示,终端设备210设备有2个天线面板:天线面板1和天线面板2。
终端设备210支持在同一时刻有一个或多个天线面板进行上行发送。示例性的,终端设备支持在同一时刻只有一个天线面板进行上行发送:终端设备控制天线面板1通过上行发送波束方向1进行上行发送。示例性的,终端设备支持在同一时刻支持2个天线面板都进行上行发送:终端设备控制天线面板1通过上行发送波束方向1进行上行发送,天线面板2通过上行发送波束方向2进行上行发送。
一个天线面板对应于一个或多个上行波束方向。示例性的,天线面板2在时刻1对应于上行发送波束方向2,在时刻2对应于上行发送波束方向3。
图3示出了本公开一个示例性实施例提供的上行发送方法的流程图,应用于如图1所示的终端设备和网络设备中。该方法包括:
步骤301,网络设备向终端设备发送RRC消息。
其中,无线资源控制(Radio Resource Control,RRC)消息用于指示上行波束信息集合,上行波束信息集合中的多个上行波束信息对应于终端设备的同一个或不同的多个天线面板。
上行波束信息集合包括至少两个个上行波束信息。示例性的,上行波束信息集合为:上行波束信息1、上行波束信息2,其中,上行波束信息1、上行波束信息2都对应于终端设备的天线面板1。示例性的,上行波束信息集合为:上行波束信息1、上行波束信息2和上行波束信息3。其中,上行波束信息1对应于终端设备的天线面板1,上行波束信息2和上行波束信息3对应于终端设备的天线面板2。
可选地,上行波束信息包括:空间关系信息(spatial relation info)、传输配置指示(Transmission Configuration Indication,TCI)状态,和上行TCI状态中的任意一种。
步骤302,终端设备接收RRC消息。
终端设备根据接收到的RRC消息,确定上行波束信息集合。
在一个示例中,上行波束信息集合中的上行波束信息对应于至少两个天线面板。或者说,在上行波束信息集合中,存在至少两个上行波束信息对应的天线面板不同。
步骤303,网络设备向终端设备发送第一下行信令。
第一下行信令包括若干个信息域,其中的一个信息域为上行波束信息域。本公开实施例对第一下行信令的具体格式不进行限定。
第一下行信令包括但不限于:DCI信令和MAC信令中的一种。在第一下行信令是DCI信令时,上行波束信息域用于指示PUSCH的上行波束;在第一下行信令是MAC信令时,上行波束信息域用于指示物理上行控制信道(Physical Uplink Control Channel,PUCCH)的上行波束。
步骤304,终端设备接收第一下行信令。
步骤305,终端设备根据第一下行信令携带的上行波束信息域,在上行波束信息集合中确定出目标上行波束信息。
其中,上行波束信息域对应于一个或多个目标上行波束信息。
可选地,上行波束信息域的一种取值称为一个码点。如,对于1bit的上行波束信息域,包括两个码点:0和1。上行波束信息域对应于一个或多个目标上行波束信息指的是上行波束信息域的所有码点中的每个码点(code point)对应于一个或多个目标上行波束信息。
示例性的,上行波束信息域包括3个比特。其中,码点000对应于1个上行波束信息:上行波束信息0。码点001对应于2个上行波束信息:上行波束信息2和上行波束信息3。
终端设备在第一下行信令中确定出上行波束信息域,再根据上行波束信息域的比特码字,在上行波束信息集合中确定出与该比特码字对应的目标上行波束信息。
步骤306,终端设备将目标上行波束信息对应的上行发送波束方向,确定为目标上行发送波束方向。
其中,一个目标上行波束信息对应于一个上行发送波束方向。可选地,终端设备在确定目标上行波束信息(一个或多个)后,将上述上行波束信息对应的上行发送波束方向(一个或多个),确定为目标上行发送波束方向(一个或多个)。若终端设备支持在同一时刻只有一个天线面板进行上行传输,则该天线面板使用确定好的一个目标上行发送波束方向进行上行传输;若终端设备支持在同一时刻有多个天线面板进行上行传输,则多个天线面板使用各自的目标上行发送波束方向进行上行传输。
示例性的,目标上行波束信息是空间关系信息。目标上行发送波束方向与空间关系信息指示的SRS的发送波束方向一样;或,与空间关系信息指示的SSB的接收波束对应的发送波束方向一样;或,与空间关系信息指示的非零功率CSI-RS的接收波束对应的发送波束方向一样。
示例性的,目标上行波束信息是(上行)TCI状态。目标上行发送波束方向与(上行)TCI状态指示的SRS的发送波束方向一样;或,与(上行)TCI状态指示的SSB的接收波束对应的发送波束方向一样;或,与(上行)TCI状态指示的非零功率CSI-RS的接收波束对应的发送波束方向一样。
综上所述,本实施例提供的方法,由网络设备下发的RRC消息指示的上行 波束集合中的上行波束可以对应于终端设备的多个天线面板,从而终端设备可以后续根据第一下行信令中的上行波束信息域的指示,在上行波束集合中确定出目标上行波束信息,由终端设备的一个或多个天线面板根据目标波束信息对应的目标上行发送波束方向进行上行发送,以适应多个天线面板上更多波束的动态切换。
在基于图3的可选实施例中,包括如下3个场景:
场景1:终端设备支持在同一时刻只有一个天线面板进行上行发送,上行波束信息域对应于一个目标上行波束信息。
场景2:终端设备支持在同一时刻只有一个天线面板进行上行发送,上行波束信息域对应于一个或多个目标上行波束信息。
场景3:终端设备支持在同一时刻有一个或多个天线面板进行上行发送,上行波束信息域对应于一个或多个目标上行波束信息。
需要说明的是,上述3个场景中,第一下行信令是MAC信令或DCI信令。
情况1:第一下行信令是DCI信令。
针对场景1,结合参考图4。图4示出了本公开一个示例性实施例提供的上行发送方法的流程图,应用于如图1所示的终端设备和网络设备中。
在本实施例中,终端设备支持在同一时刻只有一个天线面板进行上行发送,上行波束信息域对应于一个目标上行波束信息,第一下行信令为DCI信令。在本实施例中,步骤305替换实现为步骤3051和步骤3052:
步骤301,网络设备向终端设备发送RRC消息。
步骤302,终端设备接收RRC消息。
可选地,上行波束信息集合中的上行波束信息携带有指示标识,指示标识用于指示上行波束信息对应的天线面板;其中,指示标识包括:小区(cell)ID、传输接收点(Transmission Reception Point,TRP)ID、天线面板(panel)ID、参考信号资源或资源集ID中的至少一种。
示例性的,指示标识包括:小区ID。在每个小区只有一个天线面板的情况下,根据小区ID,即可确定对应的天线面板。小区ID可以是服务小区的小区ID,或者是邻小区的小区ID。
示例性的,指示标识包括:传输接收点ID。在每个传输接收点只有一个天 线面板的情况下,根据传输接收点ID,即可确定对应的天线面板。
示例性的,指示标识包括:天线面板ID。天线面板ID用于唯一的标识一个天线面板,根据天线面板ID,即可确定对应的天线面板。天线面板ID可以是网络设备端的天线面板ID,或者是终端设备侧的天线面板ID。当天线面板ID为网络设备端时,也可以使用CORESET(Control Resource Set,控制资源集合)ID。
示例性的,指示标识包括:参考信号资源ID或资源集ID。参考信号资源ID或资源集ID用于区分天线面板。在每个小区(或传输接收点)只有一个天线面板的情况下,参考信号资源ID或资源集ID也可用于区分小区(或传输接收点),根据参考信号资源ID或资源集ID,即可确定对应的天线面板。
步骤3051,终端设备在上行波束信息集合中确定出多个激活的候选上行波束信息。
对于上行波束信息集合中的上行波束信息,终端对所有或部分的上行波束信息进行激活,将激活的上行波束信息作为候选上行波束信息。
在一个可选的实施例中,在上行波束信息集合中确定出多个激活的候选上行波束信息,包括:在上行波束信息集合中上行波束信息的个数小于或等于M的情况下,确定上行波束信息集合中所有上行波束信息为候选上行波束信息,M为正整数;在上行波束信息集合中的上行波束信息的个数大于M的情况下,接收MAC信令;根据MAC信令,在上行波束信息集合中激活M个上行波束信息为候选上行波束信息。
示例性的,M为8。上行波束信息集合中的上行波束信息的个数为6个,则将这6个上行波束信息都激活,确定为候选上行波束信息;上行波束信息集合中的上行波束信息的个数为10个,则需要根据MAC信令激活其中的8个上行波束信息,将激活的8个上行波束信息确定为候选上行波束信息。
步骤303a,网络设备向终端设备发送DCI信令。
步骤304a,终端设备接收DCI信令。
步骤3052,终端设备根据DCI信令中的上行波束信息域,在多个候选上行波束信息中确定出目标上行波束信息。
DCI信令直接指示在所有的候选上行波束信息中的一个候选上行波束信息作为目标上行波束信息,将目标上行波束信息提供给终端设备。
可选地,终端设备对激活的多个候选上行波束信息按顺序从0开始进行重新编号。上行波束信息域的每个码点对应于一个重新编号后的候选上行波束信 息。
示例性的,被MAC信令激活的8个候选上行波束信息为:候选上行波束信息#3,候选上行波束信息#8,候选上行波束信息#13,候选上行波束信息#15,候选上行波束信息#16,候选上行波束信息#19,候选上行波束信息#21,候选上行波束信息#23。对这8个候选上行波束信息重新编号为0~7,即候选上行波束信息#3变为候选上行波束信息#0(对应于码点000),候选上行波束信息#8变为候选上行波束信息#1(对应于码点001),候选上行波束信息#13变为候选上行波束信息#2(对应于码点010),候选上行波束信息#15变为候选上行波束信息#3(对应于码点011),候选上行波束信息#16变为候选上行波束信息#4(对应于码点100),候选上行波束信息#19变为候选上行波束信息#5(对应于码点101),候选上行波束信息#21变为候选上行波束信息#6(对应于码点110),候选上行波束信息#23变为候选上行波束信息#7(对应于码点111)。
步骤306,终端设备将目标上行波束信息对应的上行发送波束方向,确定为目标上行发送波束方向。
由于上行波束信息域对应于一个目标上行波束信息,终端设备可以确定出一个目标上行发送波束方向。在终端设备支持在同一时刻只有一个天线面板进行上行发送的情况下,终端设备将上述目标上行发送波束方向作为天线面板1(正在进行上行发送的天线面板)的发送波束方向。
综上所述,本实施例提供的方法,第一下行信令是DCI信令时,在终端设备支持在同一时刻只有一个天线面板进行上行发送的情况下,上行波束信息域对应于一个目标上行波束信息,使得终端设备可以根据上行波束信息域,在RRC消息给出的上行波束信息集合中确定出一个目标上行波束信息,使用目标上行波束信息对应的上行发送波束方向作为天线面板的上行发送波束方向。
针对场景2和场景3,结合参考图5。图5示出了本公开一个示例性实施例提供的上行发送方法的流程图,应用于如图1所示的终端设备和网络设备中。
在本实施例中,终端设备支持在同一时刻有一个或多个天线面板进行上行发送,上行波束信息域对应于一个或多个目标上行波束信息,第一下行信令为DCI信令。在本实施例中,步骤305替换实现为步骤3053和步骤3055:
步骤301,网络设备向终端设备发送RRC消息。
步骤302,终端设备接收RRC消息。
可选地,上行波束信息集合中的上行波束信息携带有指示标识,指示标识用于指示上行波束信息对应的天线面板;其中,指示标识包括:小区ID、传输接收点ID、天线面板ID、参考信号资源ID或资源集ID中的至少一种。
示例性的,指示标识包括:小区ID。在每个小区只有一个天线面板的情况下,根据小区ID,即可确定对应的天线面板。小区ID可以是服务小区的小区ID,或者是邻小区的小区ID。
示例性的,指示标识包括:传输接收点ID。在每个传输接收点只有一个天线面板的情况下,根据传输接收点ID,即可确定对应的天线面板。示例性的,指示标识包括:天线面板ID。天线面板ID用于唯一的标识一个天线面板,根据天线面板ID,即可确定对应的天线面板。天线面板ID可以是网络设备端的天线面板ID,或者是终端设备侧的天线面板ID。当天线面板ID为网络设备端时,也可以使用CORESET ID。
示例性的,指示标识包括:参考信号资源ID或资源集ID。参考信号资源ID或资源集ID用于区分天线面板。在每个小区(或传输接收点)只有一个天线面板的情况下,参考信号资源ID或资源集ID也可用于区分小区(或传输接收点),根据参考信号资源ID或资源集ID,即可确定对应的天线面板。
步骤3053,终端设备在上行波束信息集合中确定出多个激活的候选上行波束信息。
对于上行波束信息集合中的上行波束信息,终端对所有或部分的上行波束信息进行激活,将激活的上行波束信息作为候选上行波束信息。
可选地,激活的候选上行波束信息对应于不同的天线面板。如:共激活了8个候选上行波束信息,其中4个候选上行波束信息对应于天线面板1,另外4个候选上行波束信息对应于天线面板2。
在一个可选的实施例中,在上行波束信息集合中确定出多个激活的候选上行波束信息,包括:在上行波束信息集合中上行波束信息的个数小于或等于M的情况下,确定上行波束信息集合中所有上行波束信息为候选上行波束信息,M为正整数;在上行波束信息集合中的上行波束信息的个数大于M的情况下,接收MAC信令;根据MAC信令,在上行波束信息集合中激活M个上行波束信息为候选上行波束信息。
示例性的,M为8。上行波束信息集合中的上行波束信息的个数为6个,则将这6个上行波束信息都激活,确定为候选上行波束信息;上行波束信息集合 中的上行波束信息的个数为10个,则需要根据MAC信令激活其中的8个上行波束信息,将激活的8个上行波束信息确定为候选上行波束信息。
可选地,终端设备对激活的多个候选上行波束信息按顺序从0开始进行重新编号。
示例性的,被MAC信令激活的4个候选上行波束信息为:候选上行波束信息#3,候选上行波束信息#8,候选上行波束信息#13,候选上行波束信息#15,候选上行波束信息#18,候选上行波束信息#20,候选上行波束信息#26,候选上行波束信息#29。对这8个候选上行波束信息重新编号为0~7,即候选上行波束信息#3变为候选上行波束信息#0,候选上行波束信息#8变为候选上行波束信息#1,候选上行波束信息#13变为候选上行波束信息#2,候选上行波束信息#15变为候选上行波束信息#3,候选上行波束信息#18变为候选上行波束信息#4,候选上行波束信息#20变为候选上行波束信息#5,候选上行波束信息#26变为候选上行波束信息#6,候选上行波束信息#29变为候选上行波束信息#7。
步骤303a,网络设备向终端设备发送DCI信令。
步骤304a,终端设备接收DCI信令。
步骤3054,终端设备获取MAC信令携带的映射关系。
其中,映射关系用于指示上行波束信息域的比特码字与候选上行波束信息之间的对应关系。
可选地,在终端设备需要MAC信令激活候选上行信息的情况下,终端设备在步骤3053之前接收网络设备下发的MAC信令。在终端设备不需要MAC信令激活候选上行信息的情况下,终端设备在步骤3054之前接收网络设备下发的MAC信令。
示例性的,MAC信令通过如表一所示的表格,告知终端设备映射关系。
表一
Figure PCTCN2020089211-appb-000001
Figure PCTCN2020089211-appb-000002
如表一所示,上行波束信息域的一个码点对应于一个或多个目标上行波束信息。如:上行波束信息域为000时,对应于1个目标上行波束信息:上行波束信息#0。上行波束信息域为111时,对应于2个目标上行波束信息:上行波束信息#3和上行波束信息#7。
可选地,DCI中上行波束信息域的每个3bit的序列对应MAC CE中的一个8bit,比如DCI中上行波束信息域的3bit为000时,对应MAC CE中的第一个8bit,这个8bit中每个bit对应一个被激活的上行波束信息,当bit位置为1,标识000指示终端使用该上行波束信息对应的波束方向。而DCI中上行波束信息域的3bit为001时,对应MAC CE中的第2个8bit,以此类推,最多需要MAC CE的8个8bit来指示上述映射关系。可选地,当MAC CE最多激活16个上行波束信息、且DCI中上行波束信息域为4bit时,MAC CE需要16个16bit来指示上述映射关系。
步骤3055,终端设备根据上行波束信息域的比特码字信息,在映射关系中查找出对应的目标上行波束信息。
示例性的,上行波束信息域的比特码字信息为001,则目标上行波束信息为:上行波束信息#4。上行波束信息域的比特码字信息为100,则目标上行波束信息为:上行波束信息#0和上行波束信息#4。
步骤306,终端设备将目标上行波束信息对应的上行发送波束方向,确定为目标上行发送波束方向。
在终端设备支持在同一时刻只有一个天线面板进行上行发送的情况下,将目标上行波束信息对应的上行发送波束方向,确定为目标上行发送波束方向,包括:在目标上行波束信息的个数为1个的情况下,将目标上行波束信息对应的上行发送波束方向确定为目标上行发送波束方向;在目标上行波束信息的个 数为多个的情况下,将其中一个或其中多个目标上行波束信息对应的上行发送波束方向确定为目标上行发送波束方向;其中,多个目标上行波束信息对应于不同的时域资源。
示例性的,上行波束信息域的比特码字信息为110,则目标上行波束信息为:上行波束信息#2和上行波束信息#6。由于同时只有一个天线面板进行发送,所以上行波束信息#2和上行波束信息#6对应不同的时域资源。终端设备根据当前使用的时域资源,将上行波束信息#2(或上行波束信息#6)对应的发送波束方向确定为天线面板当前的目标上行发送波束方向。
在终端设备支持在同一时刻有多个天线面板进行上行发送的情况下,将目标上行波束信息对应的上行发送波束方向,确定为目标上行发送波束方向,包括:在目标上行波束信息的个数为1个的情况下,将目标上行波束信息对应的上行发送波束方向确定为目标上行发送波束方向;在目标上行波束信息的个数为多个的情况下,将其中一个或其中多个目标上行波束信息对应的上行发送波束方向确定为目标上行发送波束方向;其中,多个目标上行波束信息对应于同样的时域资源或不同的时域资源。当终端设备同一时刻支持2个天线面板进行上行发送时,2个天线面板使用不同的目标上行波束方向同时发送,而如果指示的目标上行发送波束方向数目大于2,比如为4时,两个天线面板可以在T1时刻使用其中2个目标上行波束方向同时发送,在T2时刻使用其中另外2个目标上行波束方向同时发送。
示例性的,上行波束信息域的比特码字信息为110,则目标上行波束信息为:上行波束信息#2和上行波束信息#6。其中,上行波束信息#2对应于天线面板1,上行波束信息#6对应于天线面板2。终端设备将上行波束信息#2和上行波束信息#6对应的上行发送波束方向都确定为目标上行发送波束方向。
由于同时有天线面板1和天线面板2进行上行发送,所以上行波束信息#2和上行波束信息#6可以对应同样的时域资源,或对应不同的时域资源(Time Division Multiplex,TDM)。当对应同样的时域资源时,可以使用不同的频域资源(Frequency Division Multiplex,FDM),或使用同样的频域资源但波束方向不同(Space Division Multiplex,SDM)。
综上所述,本实施例提供的方法,第一下行信令是DCI信令时,在终端设备支持在同一时刻只有一个天线面板进行上行发送的情况下,上行波束信息域对应于一个或多个目标上行波束信息,使得终端设备可以根据上行波束信息域, 在RRC消息给出的上行波束信息集合中确定出一个目标上行波束信息,使用目标上行波束信息对应的上行发送波束方向作为天线面板的上行发送波束方向。
在终端设备支持在同一时刻有多个天线面板进行上行发送的情况下,上行波束信息域对应于一个或多个目标上行波束信息,使得终端设备可以根据上行波束信息域,在RRC消息给出的上行波束信息集合中确定出一个或多个目标上行波束信息,使用目标上行波束信息对应的上行发送波束方向作为一个或多个天线面板的上行发送波束方向。
情况2:第一下行信令是MAC信令。

示例性的,指示标识包括:小区ID。在每个小区只有一个天线面板的情况下,根据小区ID,即可确定对应的天线面板。小区ID可以是服务小区的小区ID,或者是邻小区的小区ID。
示例性的,指示标识包括:传输接收点ID。在每个传输接收点只有一个天线面板的情况下,根据传输接收点ID,即可确定对应的天线面板。
示例性的,指示标识包括:天线面板ID。天线面板ID用于唯一的标识一个天线面板,根据天线面板ID,即可确定对应的天线面板。天线面板ID可以是网络设备端的天线面板ID,或者是终端设备侧的天线面板ID。当天线面板ID为网络设备端时,也可以使用CORESET ID。
示例性的,指示标识包括:参考信号资源ID或资源集ID。参考信号资源ID或资源集ID用于区分天线面板。在每个小区(或传输接收点)只有一个天线面板的情况下,参考信号资源ID或资源集ID也可用于区分小区(或传输接收 点),根据参考信号资源ID或资源集ID,即可确定对应的天线面板。
步骤303b,网络设备向终端设备发送MAC信令。
MAC信令携带有上行波束信息域,上行波束信息域用于在上行波束信息集合给出的上行波束信息中激活目标上行波束信息。目标上行波束信息用于终端设备的天线面板进行PUCCH上行发送。
步骤304a,终端设备接收MAC信令。
步骤305,终端设备根据上行波束信息域,在上行波束信息集合中确定出目标上行波束信息。
其中,上行波束信息域对应于一个或多个目标上行波束信息。
终端设备在接收到MAC信令后,根据MAC信令携带的上行波束信息域,在上行波束信息集合中激活一个或多个上行波束信息作为目标上行波束信息。
步骤306,终端设备将目标上行波束信息对应的上行发送波束方向,确定为目标上行发送波束方向。
针对场景1,由于上行波束信息域对应于一个目标上行波束信息,终端设备根据MAC信令激活的一个目标上行波束信息来确定目标上行发送波束方向。在终端设备支持在同一时刻只有一个天线面板进行上行发送的情况下,终端设备将上述目标上行发送波束方向作为天线面板1(正在进行上行发送的天线面板)的发送波束方向。
示例性的,MAC信令激活的目标上行波束信息为:上行波束信息#2,终端设备当前只有天线面板2进行上行发送,则终端设备将上行波束信息#2对应的上行发送波束方向确定为天线面板2的目标上行发送波束方向。
针对场景2,由于上行波束信息域对应于多个目标上行波束信息,终端设备根据MAC信令激活的多个目标上行波束信息来确定目标上行发送波束方向。在终端设备支持在同一时刻只有一个天线面板进行上行发送的情况下,终端设备将上述多个目标上行发送波束方向作为天线面板2(正在进行上行发送的天线面板)的发送波束方向。其中,激活的多个目标上行波束信息对应于不同的时域资源。
示例性的,MAC信令激活的目标上行波束信息为:上行波束信息#2和上行波束信息#3。由于同时只有一个天线面板进行发送,所以上行波束信息#2和上行波束信息#3对应不同的时域资源。终端设备根据当前使用的时域资源,将上行波束信息#2(或上行波束信息#3)对应的发送波束方向确定为天线面 板当前的目标上行发送波束方向。
针对场景3,由于上行波束信息域对应于多个目标上行波束信息,终端设备根据MAC信令激活的多个目标上行波束信息来确定多个目标上行发送波束方向。在终端设备支持在同一时刻有多个天线面板进行上行发送的情况下,终端设备将上述多个目标上行发送波束方向作为多个天线面板的发送波束方向。激活的多个目标上行波束信息对应于相同或不同的时域资源。
示例性的,目标上行波束信息为:上行波束信息#1和上行波束信息#2。其中,上行波束信息#1对应于天线面板1,上行波束信息#2对应于天线面板2。终端设备将上行波束信息#1和上行波束信息#2对应的上行发送波束方向都确定为目标上行发送波束方向。由于同时有天线面板1和天线面板2进行上行发送,所以上行波束信息#1和上行波束信息#2可以对应同样的时域资源,或对应不同的时域资源。当对应同样的时域资源时,可以使用不同的频域资源,或使用同样的频域资源但波束方向不同。
综上所述,本实施例提供的方法,第一下行信令为MAC信令,由于RRC信令给出的上行波束集合中的上行波束信息可以对应于不同的天线面板,终端设备可以根据MAC信令在上行波束集合中确定出一个或多个目标上行波束信息,使用目标上行波束信息对应的上行发送波束方向作为多个天线面板的上行发送波束方向。

终端设备的相同天线面板的不同上行发送波束之间的切换时间中的至少一 种。
示例性的,终端设备设置有2个天线面板,包括:天线面板1和天线面板2。终端设备不支持2个天线面板同时进行上行发送,终端设备上报的天线面板信息包括:切换时间1。若终端设备需要切换进行上行发送的天线面板,如:由天线面板1切换至天线面板2,则需要切换时间1执行上述切换过程。
示例性的,终端设备的天线面板1在执行上行发送,终端设备上报的天线面板信息包括:切换时间2。天线面板1需要由上行发送波束1切换至上行发送波束2,则需要切换时间2执行上述切换过程。
可选地,终端设备处在空闲(idle)状态的情况下,使用非接入层(Non-Access Stratum,NAS)信令将天线面板信息发送给核心网,由核心网转发给网络设备。终端设备处在连接(connected)状态的情况下,网络设备向终端设备请求天线面板信息,终端设备使用RRC信令将天线面板信息发送给网络设备。
步骤308,网络设备接收天线面板信息。
网络设备根据接收到的天线面板信息,确定终端设备的多个天线面板的上行激活能力,或,上行发送能力。
可选地,网络设备根据接收到的天线面板信息,向终端设备发送DCI信令,以确定目标上行发送波束方向。
综上所述,本实施例提供的方法,在终端设备确定天线面板的上行发送波束方向之前,需要向网络设备上报自身的天线面板信息,使得网络设备可以根据终端设备的情况,为终端设备下发DCI信令。
需要说明的是,上述方法实施例可以分别单独实施,也可以组合实施,本公开对此不进行限制。
