Abstract

Description

TCI状态的确定方法、装置、设备及存储介质 技术领域
本申请涉及移动通信领域,特别涉及一种TCI状态的确定方法、装置、终端及介质。
背景技术
在新空口(New Radio,NR)系统中,特别是通信频段在频段范围2时,由于高频信道衰减较快,为了保证覆盖范围,需要使用基于波束(beam)的发送和接收。
当网络设备有多个TRP时,网络设备可以使用多个TRP为终端提供服务,包括使用多个TRP为终端发送PDCCH。传统方法中,网络设备使用一个TRP为终端发送PDCCH时,CORESET配置一个TCI状态,那么与该CORESET关联的搜索空间集的TCI状态都与该CORESET的TCI状态一样。
当使用多个TRP的PDCCH的重复发送方法时,相当于终端需要使用不同TCI状态对应的波束来接收不同TRP发送的PDCCH,而这多个PDCCH可能来自相同的或不同的搜索空间集(Search Space Set,SS set),如何指示搜索空间集的TCI状态,是需要解决的问题。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
在本公开以下的所有实施例中,虽然不同的步骤采用了数字来进行编号,但是这些编号都只是为了使得文字更为清楚的目的而进行的编号,并非是对于步骤的执行顺序和时隙的限定。本公开的所有实施例中,这些编号的步骤可以被单独实施,也可以被任何组合在一起实施;当这些步骤被任意组合在一起实施时,其执行顺序并不受到编号的数字的限制,即其可以以任意的顺序被执行。
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14提供无线通信功能的装置统称为网络设备。在车联网通信中,网络设备还可以是车载终端。
终端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、计算设备或物联网(Internet of Things,IoT)设备或工业物联网(Industry Internet of Things,IIoT)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。网络设备120与终端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:频分双工(Frequency Division Duplex,FDD)系统、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。
本申请提出了一种搜索空间集的TCI状态的指示方法,使得终端能够确定多个TRP传输的PDCCH各自对应的TCI状态,从而提高DCI信令的接收成功率。
图2示出了本申请一个实施例提供的TCI状态的确定方法的流程图。本实施例以该方法由终端执行来举例说明,所述方法包括:
步骤202:接收指示信令;
终端接收网络设备发送的指示信令。指示信令为无线资源控制(Radio Resource Control,RRC)信令、媒体接入控制(Medium Access Control,MAC)信令和下行控制信息(Downlink Control Information,DCI)信令中的至少一种。
步骤204:根据指示信令确定终端的搜索空间集(Search Space set,SS set)对应的N个TCI状态,N为正整数。
终端根据指示信令确定终端的搜索空间集对应的N个TCI状态,N可以为1个,也可以为两个或两个以上。
综上所述,本实施例提供的方法,通过提出了当网络设备使用多个TRP为终端发送PDCCH服务时,当同一CORESET的不同SS set对应不同TRP,或同一SS set的不同PDCCH候选位置(candidate)对应不同TRP,或一个SS set对应多个CORESET时,提出了不同SS set或不同PDCCH candidate的TCI状态指示方法,使得终端能按照正确的TCI状态来接收对应的PDCCH资源块上发送的DCI,提高DCI的解码成功率。
上述指示信令可以采用显式配置方式,或隐式配置方式。
针对显式配置方式:
在基于图2的可选实施例中,上述步骤204可替代实现成为步骤204a,如图3所示:
步骤204a:从指示信令中读取搜索空间集的配置,搜索空间集的配置包括:搜索空间集对应的N个TCI状态的TCI状态标识。
在搜索空间集为一个或多个时,终端从指示信令中读取每个搜索空间集的配置,第i个搜索空间集的配置包括:第i个搜索空间集对应的N i个TCI状态的TCI状态标识。其中,i为正整数。
示意性的,TCI状态标识包括:TCI状态的绝对标识。
比如:网络设备向终端发送无线资源控制(Radio Resource Control,RRC)信令,该RRC信令为发送PDCCH的所有CORESET配置了64个TCI状态,那么用于该搜索空间集的TCI状态的标识取值为0~63中的其中一个或多个。即每个TCI状态还需要6bit来指示(因为有64个TCI状态)。如表一所示:
表一
搜索空间集 TCI状态标识
搜索空间集1 000001、000010、000011
搜索空间集2 110001、110010、110011
示意性的,TCI状态标识包括:TCI状态在搜索空间集所属的一个CORESET对应的M个TCI状态按照编号排序后的序号,其中M为大于1的整数。
比如网络设备向终端发送RRC信令,RRC信令为搜索空间集所属的CORESET配置了64个TCI状态,网络设备再向终端发送MAC信令,该MAC信令为搜索空间集所属的CORESET配置了TCI#3,TCI#5,那么该搜索空间集对应的TCI状态的序号可以为新TCI#0(对应TCI#3)和/或新TCI#1(对应TCI#5),即每个TCI状态只需要1bit来指示,因为搜索空间集所属的CORESET只配置了2个TCI状态。
综上所述,本实施例提供的方法,通过网络设备向终端发送显式配置的指示信令,使得当网络设备使用多个TRP为终端发送PDCCH服务时,提出了不同搜索空间集的TCI状态指示方法,使得终端能按照正确的TCI状态来接收对应的PDCCH资源块上发送的DCI,提高DCI的解码成功率。
针对隐式配置方式:
每个搜索空间集的TCI状态与所属的CORESET对应的TCI状态有默认的映射关系。
映射方式一(排名不分先后):
在基于图2的可选实施例中,上述步骤204可替代实现成为步骤204b和步骤204c,如图4所示:
步骤204b,从指示信令中读取搜索空间集所属的CORESET和CORESET对应的TCI状态;
同一个搜索空间集可以属于一个或多个CORESET。
以搜索空间集对应多个CORESET为例,终端从指示信令中读取至少两个CORESET和每个CORESET对应的TCI状态。可选地,每个CORESET对应的TCI状态为一个。
步骤204c,将搜索空间集所属的CORESET对应的TCI状态,均确定为搜索空间集对应的TCI状态。
终端将同一个搜索空间集所属的各个CORESET对应的TCI状态,均确定为搜索空间集对应的TCI状态。
映射方式二:
在基于图2的可选实施例中,上述步骤204可替代实现成为步骤204d和步骤204e,如图5所示:
步骤204d:从指示信令中读取搜索空间集所属的CORESET对应的M个TCI状态,M为正整数;
同一个搜索空间集可以属于一个或多个CORESET。每个CORESET对应M个TCI状态。需要说明的是,每个CORESET对应的TCI状态的个数相同或不同。在存在至少两个CORESET对应的TCI状态不同的情况下,第i个CORESET对应的TCI状态的个数为M i
在一个示例中,M为大于1的整数。也即,一个CORESET对应的TCI状态可以为多个。
以搜索空间集对应一个CORESET为例,终端从指示信令中读取该CORESET和该CORESET对应的M个TCI状态。以搜索空间集对应两个以上的CORESET为例,终端从指示信令中读取至少两个CORESET和每个CORESET对应的M i个TCI状态。第i个CORESET对应的TCI状态的个数为M i,i为正整数。
步骤204e:将M个TCI状态中的全部或一部分TCI状态,确定为搜索空间集对应的TCI状态。
终端将M个TCI状态中的N个TCI状态,确定为单个搜索空间集对应的TCI状态,其中,N为不大于M的整数。或者,终端将M个TCI状态中的一个或多个TCI状态,确定为单个搜索空间集对应的TCI状态。属于同一个CORESET的搜索空间集可以为多个。
可选地,在N=1的情况下,终端按照预设映射关系将M个TCI状态中的一个TCI状态,确定为搜索空间集对应的TCI状态。也即,终端将M个TCI状态中的一个TCI状态,确定为单个搜索空间集对应的TCI状态。至少可以采用如下三种方式中的任意一种:
·终端根据搜索空间集的标识,按照循环映射(Cyclical mapping)方式确定搜索空间集对应的一个TCI状态;
比如M为2,即CORESET配置了2个TCI状态(TCI#3和TCI#5)。那么:SS set ID为0,2,4……对应TCI#3;SS set ID为1,3,5……对应TCI#5。
·终端根据搜索空间集的标识,按照顺序映射(Sequential mapping)方式确定搜索空间集对应的一个TCI状态;
比如M为2,即CORESET配置了2个TCI状态(TCI#3和TCI#5)。SS set ID为0,1,2对应TCI#3;SS set ID为3,4,5对应TCI#5。
·终端确定搜索空间集对应的搜索空间集组(pair),搜索空间集组内的M个搜索空间集与M个TCI状态一一对应。
比如M为2,即CORESET配置了2个TCI状态(TCI#3和TCI#5)。一个搜索空间集组为搜索空间集#0和搜索空间集#1,则搜索空间集#0对应TCI#3,搜索空间集#1对应TCI#5。另一个搜索空间集组为搜索空间集#2和搜索空间集#3,则搜索空间集#2对应TCI#3,搜索空间集#3对应TCI#5。即搜索空间集的ID较小者对应TCI状态中的编号较小者。
这种情况下,当存在至少一个搜索空间集不是以组形式出现的情况下,默认这些搜索空间集对应CORESET的M个TCI状态,或者M个TCI状态中编号最小的一个TCI状态。
综上所述,本实施例提供的方法,通过网络设备向终端发送隐式配置的指示信令,相比于上一个实施例,能够减少指示信令所需要携带的数据量,从而节约空口资源。
在基于上述各个实施例的基础上,当一个搜索空间集对应多个TCI状态时,还可能包括两种情况:
·该搜索空间集中的每个PDCCH候选位置都对应该多个TCI状态;
在搜索空间集为对应多个TCI状态的第一搜索空间集,第一搜索空间集包括至少两个PDCCH候选位置的情况下,至少两个PDCCH候选位置中的每个PDCCH候选位置均对应该多个TCI状态。
·该搜索空间集中的不同PDCCH候选位置对应不同TCI状态。
在搜索空间集为对应多个TCI状态的第一搜索空间集,第一搜索空间集包括至少两个PDCCH候选位置的情况下,至少两个PDCCH候选位置中的不同PDCCH候选位置对应不同TCI状态。
在一个示例中,终端从指示信令读取至少两个PDCCH候选位置对应的TCI状态标识。比如,指示信令中显式配置有每个PDCCH候选位置对应的TCI状态标识,该TCI状态标识是绝对标识,该TCI绝对标识可以是0-63;或该TCI状态标识是该第一搜索空间集对应的多个TCI状态标识按照编号重新排序后的序号。比如第一搜索空间集对应的TCI#3,TCI#5,那么该至少两个PDCCH候选位置对应的TCI状态的序号可以为新TCI#0(对应TCI#3)和/或新TCI#1(对应TCI#5),这样,每个PDCCH候选位置对应的TCI状态标识只需要1bit来指示即可。
在另一个示例中,终端按照循环映射方式确定至少两个PDCCH候选位置对应的TCI状态。比如:第一搜索空间集对应TCI状态#1和TCI状态#2,4个PDCCH候选位置分别对应TCI状态#1、TCI状态#2、TCI状态#1、TCI状态#2。
在另一个示例中,终端按照顺序映射方式确定至少两个PDCCH候选位置对应的TCI状态。比如:第一搜索空间集对应TCI状态#1和TCI状态#2,4个PDCCH候选位置分别对应TCI状态#1、TCI状态#1、TCI状态#2、TCI状态#2。
需要说明的是,至少两个PDCCH候选位置的PDCCH聚合等级一样或不一样。
综上所述,本实施例提供的方法,通过提出了当网络设备使用多个TRP为终端发送PDCCH服务时,当同一SS set的不同PDCCH候选位置对应不同TRP时,提出了不同PDCCH候选位置的TCI状态指示方法,使得终端能按照正确的TCI状态来接收对应的PDCCH资源块上发送的DCI,提高DCI的解码成功率。
