在一些实施例中,终端11之间还可以建立E2E(End to End,端到端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通信和V2P(vehicle to pedestrian,车对人)通信等场景。
在一些实施例中,上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连接。其中,网络管理设备13可以是无线通信系统中的核心网设备,比如,该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备13的实现形态,本公开实施例不做限定。
为了改善小区边缘的覆盖,在服务区内提供更为均衡的服务质量,多点协作传输(Coordinated Multiple Point transmission,CoMP)在新空口(NR,New Radio)系统中仍然是一种重要的技术手段。从网络形态角度考虑,以大量的分布式接入点结合基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率,并且显著的降低越区切换带来的时延和信令开销。随着频段的升高,从保证网络覆盖的角度出发,也需要相对密集的接入点部署。而在高频段,随着有源天线设备集成度的提高,将更加倾向于采用模块化的有源天线阵列。
根据发送信号流到多个收发点(TRP,Transmit Receive Point)/天线面板上的映射关系,多点协作传输技术可以分为相干和非相干传输两种。其中,相干传输时,每个数据层会通过加权向量映射到多个TRP/面板之上。而非相干传输时,每个数据流只映射到部分的TRP/面板上。相干传输对于传输点之间的同步以及回程链路的传输能力有着更高的要求,因而对现实部署条件中的很多非理想因素较为敏感。相对而言,非相干传输受上述因素的影响较小,因此是多点传输技术的重点考虑方案。
准共址(QCL,Quasi Co-Location)是指某个天线端口上的符号所经历 的信道的大尺度参数可以从另一个天线端口上的符号所经历的信道所推断出来。其中的大尺度参数可以包括时延扩展、平均时延、多普勒扩展、多普勒偏移、平均增益以及空间接收参数等。
QCL的概念是随着多点协作传输技术的出现而引入的。多点协作传输过程中涉及到的多个可能对应于多个地理位置不同的站点(包括:TRP)或者天线面板朝向有差异的多个扇区。例如当终端从不同的站点接收数据时,各个站点在空间上的差异会导致来自不同站点的接收链路的大尺度信道参数的差别,如多普勒频偏,时延扩展等。而信道的大尺度参数将直接影响到信道估计时滤波器系数的调整与优化,对应于不同站点发出的信号,应当使用不同的信道估计滤波参数以适应相应的信道传播特性。
因此,尽管各个站点在空间位置或角度上的差异对于UE以及CoMP操作本身而言是透明的,但是上述空间差异对于信道大尺度参数的影响则是UE进行信道估计与接收检测时需要考虑的重要因素。所谓两个天线端口在某些大尺度参数意义下QCL,就是指这两个端口的这些大尺度参数是相同的。或者说,只要两个端口的某些大尺度参数一致,不论他们的实际物理位置或对应的天线面板朝向是否存在差异,终端就可以认为这两个端口是发自相同的位置(即准共站址)。
针对一些典型的应用场景,考虑到各种参考信号之间可能的QCL关系,从简化信令的角度出发,NR中将几种信道大尺度参数分为以下4个类型,便于系统根据不同场景进行配置/指示:
QCL-TypeA:{Doppler频移,Doppler扩展,平均时延,时延扩展}
-除了空间接收参数之外,的其他大尺度参数均相同。
-对于6GHz以下频段而言,可能并不需要空间接收参数。
QCL-TypeB:{Doppler频移,Doppler扩展}
-仅针对6GHz以下频段的如下两种情况。
QCL-TypeC:{Doppler频移,平均时延}
QCL-TypeD:{空间接收参数}
-如前所述,由于这一参数主要针对6GHz以上频段,因此将其单独作为一个QCL type。
NR Release 15(Rel-15)中规定,在每个码分多路复用(CDM,Code Division Multiplexing)组内的解调参考信号(DMRS,Demodulation Reference Signal)端口是QCL的。
一种多点协作传输的场景如图2所示,包括1个终端和多个TRP。如图3所示,终端可以向多个基站的TRP方向进行上行PUSCH传输。终端可以采用时分复用技术(TDM,Time-Division Multiplexing)传输方式的进行协作传输。终端通过时域上的不同传输时机分时向基站的不同TRP发送PUSCH的同一TB。这种方法对终端能力的要求比较低,不要求支持同时发送波束的能力,而且传输时延较大。
针对上行传输,面向不同TRP的PUSCH信道,实际经过的信道可能空间特性差别很大,因此,认为不同的发送方向PUSCH信道的QCL-D不同。
根据发送信号流到多个TRP/天线面板(Panel)上的映射关系,多点协作传输技术可以大致分为相干和非相干传输两种。
相干传输时,每个数据传输层会通过加权向量映射到参与协作传输的多个TRP/天线面板上。如果各个TRP/天线面板的信道大尺度参数相同,而且使用了相同的频率源,那么相干传输等效于将多个子阵拼接成为更高维度的虚拟阵列,从而能够获得更高的赋形/预编码/复用增益。但是,在实际的部署环境中,这种方式对于传输点之间的同步以及回程(backhaul)的传输能力有着更高的要求。
非相干传输,是指每个数据流只映射到信道大尺度参数一致(即QCL) 的TRP/天线面板所对应的端口上,不同的数据流可以被映射到QCL不同的端口上,不需要将所有的协作点(协作传输的多个TRP/天线面板)统一作为一个虚拟阵列并对每个层都进行联合赋形。
联合传输可以包括:动态传输点选择(DPS,Dynamic Point Select)传输,相干联合传输(C-JT,Coherent-Joint Transmission)以及非相干联合传输(NC-JT,Non Coherent-Joint Transmission)等。如图4所示,单点传输(即DPS传输)的所有码字对应数据传输层都通过一个传输点发出;如图5所示,C-JT时,所有码字和层都通过两个传输点联合预编码之后发出;如图6所示,NC-JT方式中,码字0对应的两个数据传输层从传输点1(TP1,Transmit Point 1)发出,而码字1对应的两个数据传输层从TP2发出。
时分复用(TDM,Time Division Multiplexing)传输方式中,终端通过时域上的不同传输时机分时向基站的不同TRP发送PUSCH的同一TB,时延较大,吞吐率低。如何提高传输的可靠性和吞吐率,同时可以有效的降低多TRP下的传输时延,是亟待解决的问题。
如图7所示,本示例性实施例提供一种PUSCH配置方法,所述方法可以被蜂窝移动通信系统的网络侧设备和/或终端执行,包括:
步骤701:针对上行PUSCH的SFN传输,终端的不同天线面板配置不同的TCI;所述TCI关联于波束信息,不同的TCI同时关联相同的传输资源,其中,所述传输资源包括:时域资源和频域资源,其中,多个不同所述天线面板采用SDM进行所述PUSCH的SFN传输。
本实施例可以应用但不限于核心网设备、接入网设备等网络侧设备,和/或终端。这里终端可以包括:手持终端和/或非手持终端等。在此不进行限定。
终端可以是能够同时向多个基站的TRP方向实现多点协作传输的UE。UE能够同时向多个基站的TRP方向实现上行多点协作传输。多点协作传 输(CoMP,Coordinated Multiple Points Transmission/Reception)是指地理位置上分离的多个TRP,协同向一个终端发送数据或者协同接收一个终端发送的数据。这里,TRP可以包括:基站的天线面板等。
例如,终端能够支持通过N个天线面板同时向基站的N个TRP进行PUSCH的SFN传输,其中,N为大于或等于2的正整数。UE的每个天线面板可以分别对应于基站的一个TRP。终端的不同天线面板可以采用不同方向的波束同时进行PUSCH的SFN传输。
SFN传输可以包括:采用终端的多个天线面板在同一时间内可以采用相同的频域资源向TRP传输同一个数据内容。例如,SFN传输可以是终端采用多个天线面板在同一时间内可以采用相同的频域资源传输同一个传输块。
通过多个天线面板进行PUSCH的SFN传输,即通过多个天线面板传输相同的数据内容。网络侧设备可以通过多个TRP接收数据内容,通过联合解码等方式得数据内容,提高了上下传输的可靠性。
在一个实施例中,所述PUSCH的SFN传输,包括以下之一:
SFN的非相干传输NC-JT;
SFN的相干传输NC-JT。
在进行PUSCH的C-JT时,终端需要将发送的数据流通过多个天线面板进行联合赋形,协调不同传输点的于编码矩阵(相对相位)来保证同一个数据流在TRP端能够进行相干叠加,即将多个天线面板的子阵虚拟成一个维度更高的天线阵列来获得更高的赋形增益。各天线面板可以应用统一的预编码矩阵进行联合的预编码处理以进行C-JT。
在进行PUSCH的NC-JT时,终端不需要对多个天线面板进行联合赋形,每个天线面板可以独立对各自传输的数据李进行预编码,不需要协调相对的相位。各天线面板可以应用各所述天线面板分别对应的预编码矩阵 进行独立的预编码处理以进行NC-JT。
这里,可以分别为终端的每个天线面板配置一个TCI。TCI用于指示对应天线面板进行PUSH的SFN传输时采用的波束的波束信息。这里,波束信息至少用于指示波束的方向等。这里,TCI可以是TCI状态(TCI State)。
终端的不同天线面板配置不同的TCI,可以是网络侧设备为终端的每个天线面板配置不同的TCI。终端的不同天线面板配置不同的TCI,可以是终端为每个天线面板确定不同的TCI。这里,TCI可以是由网络侧设备发送给终端的。
在一个实施例中,所述TCI包括以下之一:
统一TCI;
空间关系信息SRI;
探测参考信号资源指示SRI。
TCI可以是统一TCI(Unified TCI)。可以在未配置有统一TCI时,使用SRI。
可以在TRP具有波束一致性时,采用统一TCI。统一TCI通过多信道和信号共享指示上下行波束,多CC使用公共的波束。TRP具有波束一致性可以包括:TRP下行接收波束和上行发射波束具有互性易,即下行接收波束和上行发射波束为波束对应(beam correspondence)。波束一致性时上行波束的方向同样是下行波束的方向。
基站也可以采用空间关系信息(SRI,Spatial Relation Info)向终端指示TCI。
基站还可以通过探测参考信号资源指示(SRI,Sounding Reference Signal RESOURCE INDICATOR)携带TCI。探测参考信号资源指示,用于在码本传输中指示上行发送PUSCH具体使用的SRS资源对应的上行发送模拟波束方向,以及在非码本的传输中指示具体发送PUSCH具体使用那几 个SRS资源的发送作为上行PUSCH的预编码,即不同层的发送波束方向。可以采用探测参考信号资源指示的预留比特位携带TCI。不同探测参考信号资源指示可以是针对不同天线面板发送的。探测参考信号资源指示中的TCI可以直接关联于接收到探测参考信号资源指示的天线面板。
在一个实施例中,所述统一TCI包括以下之一:
联合TCI;
独立TCI。
不同天线面板对应的不同的TCI可以是联合TCI,也可以是独立TCI。
统一TCI(Unified TCI)可以包括:联合(Joint)TCI和独立(separate)TCI。其中,联合TCI同时用于指示上行发送波束和下行接收波束;独立TCI用于指示上行发送波束或下行接收波束。
在一个实施例中,不同所述TCI对应于基站的不同收发点TRP方向。
TCI指示的波束可以在同一时间,如同一时隙内,采用相同的时域资源和频域资源进行传输。TCI可以通过指示不同方向的波束,实现不同天线面板采用SDM进行PUSCH的SFN传输
在一个实施例中,不同所述TCI用于指示不同的准共址类型D源参考信号,所述准共址类型D源参考信号用于确定所述TRP方向。
准共址类型D源参考信号(QCL Type-D source RS)可以包括以下至少之一:信道状态信息参考信号(CSI-RS,Channel State Information Reference Signal);同步信号广播信道块(SSB,Synchronous Signal/PBCH Block);探测参考信号(SRS,Sounding Reference Signal)。
基站和UE可以在不同的波束内交互不同的准共址类型D源参考信号,用于确定不同的可以进行通信的波束。一个准共址类型D源参考信号与一个波束具有关联关系。关联关系可以是一一对应关系。其中,不同波束的方向可以不同。
TCI可以通过准共址类型D源参考信号指示一个方向的波束。
在一个实施例中,
不同的所述统一TCI采用不同的TCI指示域承载;
或者,
不同的所述统一TCI采用一个TCI指示域承载。
可以通过多个个独立的TCI指示域分别承载一个TCI。例如,可以通过两个多个独立的TCI指示TCI,每个TCI指示域承载一个TCI,即每个TCI指示域指示一个波束方向。
也可以通过一个TCI指示域即一个TCI码点(Code Point)承载多个TCI。例如,可以通过一个TCI指示域承载两个TCI,即一个TCI指示域指示第一TRP波束方向和第二TRP波束方向。
在一个实施例中,所述PUSCH包括以下至少之一:
下行控制信息DCI调度的PUSCH;
免调度的类型1配置授权CG PUSCH;
免调度的类型2CG PUSCH。
PUSCH可以是由单个DCI调度的。DCI可以是通过PDCCH资源传送的。
配置授权(Configured Grant)CG PUSCH又分为两种类型:类型1(type1)和类型2(type2)。其中类型1CG PUSCH可以由RRC信令配置全部参数,一旦配置后便可以周期性发送。类型2CG PUSCH可以由RRC信令配置部分参数,然后需要下行控制信息(DCI,Downlink Control Information)激活/去激活,并在激活DCI中给出其他部分参数,激活后可以周期性使用。
在一个实施例中,所述TCI携带于以下至少之一
无线资源控制RRC信令;
媒体访问控制控制单元MAC-CE信令;
DCI信令。
基站可以通过不同的信令携带TCI,提高指示TCI的灵活性。
如此,一方面,通过不同TCI分别指示不同天线面板的波束信息,每个天线面板的波束信息可以单独配置,提高了波束配置的灵活性。另一方面,通过SDM方式进行上行PUSCH的SFN传输,多个天线面板同时进行传输降低了多TRP下的上行传输延时,提高了吞吐率,不同天线面板可以传输相同的数据内容,提高传输可靠性。多个天线面板采用相同的传输资源进行传输,节省了传输资源,提高传输资源利用率。
在一个实施例中,不同所述TCI关联的数据传输层集合相同,其中,一个所述数据传输层集合包括:一个或多个数据传输层。
TCI关联的数据传输层集合,可以是TCI关联的天线面板发送的数据传输层集合。每个TCI关联的数据传输层集合相同,即每个天线面板发送的数据传输层相同。不同天线面板可以传输相同的数据内容,提高传输可靠性。
例如,终端具有两个天线面板,两个天线面板对应的TCI的数据传输层集合包括数据传输层(Layer)1、数据传输层2、数据传输层3和数据传输层4,共4个数据传输层。如两个天线可以分别采用相同的传输资源传输4个数据传输层。
在一个实施例中,进行所述PUSCH的传输,所述终端各天线面板采用的最大数据传输层数为:min{N-p1,N-p2,…N-pX};
其中,X为所述终端具有的天线面板总数;所述N-px为第x个所述天线面板支持的最大数据传输层数;x为小于或等于X的正整数。
不同天线面板可以支持的数据传输层可以不同或相同。由于不同天线面板传输的数据传输层相同,因此,数据传输层数量需要满足数据传输层数支持能力最小的天线面板的支持能力。因此,TCI关联的数据传输层中数 据传输层的最大数量可以是各天线面板中数据传输层数支持能力最小的天线面板能支持的数据传输层数。
示例性的,终端可以向基站等网络侧设备上报终端的不同天线面板支持的最大源参考信号(SRS,source Reference Signal)资源包含的最大端口数(网络侧设备可以根据最大端口数,确定天线面板能支持的最大数据传输层数。例如,可以将最大端口数确定为天线面板能支持的最大数据传输层数),或UE能支持的最大数据传输层数。网络侧设备在向终端指示TCI时,可以基于各天线面板能支持的最大数据传输层数,确定数据传输层集合中数据传输层的数量。
例如,UE的两个天线面板(天线面板1和天线面板2)能支持的最大数据传输层数分别为N_p1和N_p2。在CW映射过程中支持的最大数据传输层数为:min{N_p1,N_p2}。CW可以映射到I个数据传输层,其中,I小于或等于min{N_p1,N_p2}。
如图8所示,本示例性实施例提供一种PUSCH配置方法,所述方法可以被蜂窝移动通信系统的网络侧设备和/或终端执行,包括:
步骤801:所述终端的不同天线面板进行所述PUSCH的一个传输块TB对应的单个码字CW传输,其中,所述单个CW关联于一个所述数据传输层集合。
这里,1个TB可以通过数据处理后得到1个码字(CW,Code Word)。数据处理可以包括:码块分割、信道编码、速率匹配、码块串联等。1个TB的CW可以映射在同一时隙的相同时频资源上的M个数据传输层,其中M为大于或等于1的正整数。由终端的多个天线面板均发送M个数据传输成。
示例性的,如图9所示,以终端具有两个天线面板为例。天线面板1对应TCI关联的数据传输层集合包括数据传输层(Layer)1、数据传输层2、 数据传输层3和数据传输层4。天线面板2对应TCI关联的数据传输层集合同样包括数据传输层(Layer)1、数据传输层2、数据传输层3和数据传输层4两个数据传输层。1个TB的CW可以被映射到4个数据传输层:数据传输层1、数据传输层2,数据传输层3和数据传输层4,即4个数据传输层的数据构成一个CW。发送时,天线面板1和天线面板2均发送数据传输层1、数据传输层2,数据传输层3和数据传输层4。这里,一个天线面板对应于一个TRP。每个TRP可以对应于一个波束方向。各TRP的波束方向不同。
如此,多个天线面板采用不同方向的波束均发送一个TB的多个数据传输层,实现了SDM。多个天线面板同时进行传输,在一个或多个天线由于传输环境影响,产生的发送失败等问题时,可以通过多个TRP分别接收到的多个数据传输层进行合并解码等,从而得到完整的数据。提高了传输的可靠性。
在一个实施例中,所述终端的不同天线面板使用单个冗余版本RV进行所述PUSCH的所述单个码字CW传输。
如图10所示,针对于1个TB对应于一个CW。一个TB可以基于一个冗余版本进行速率匹配(RATE MATCHING)等得到一个CW。将编码比特存储在循环缓存中,每次传输时根据冗余版本从循环缓存中顺序读取,实现速率匹配。
RV可以是由网络侧携带在DCI中向终端指示的。
在一个实施例中,
响应于进行所述PUSCH的NC-JT,各所述天线面板各所述天线面板分别对应的预编码矩阵进行独立的预编码处理;
或者,
响应于进行所述PUSCH的C-JT,所有所述天线面板应用一个预编码 矩阵进行联合的预编码处理。
针对于进行PUSCH的NC-JT,终端不需要对多个天线面板进行联合赋形,每个天线面板可以独立对各自传输的数据传输层进行预编码,不需要协调相对的相位。各天线面板可以应用各天线面板分别对应的预编码矩阵进行独立的预编码处理以进行NC-JT。
针对于进行PUSCH的C-JT,终端可以将每个天线面板各自传输的数据传输层通过多个天线面板进行联合赋形,协调不同传输点的预编码矩阵(相对相位)来保证同数据传输层在TRP端能够进行相干叠加,即将多个天线面板的子阵虚拟成一个维度更高的天线阵列来获得更高的赋形增益。各天线面板可以应用统一的一个预编码矩阵进行联合的预编码处理以进行C-JT。
在一个实施例中,响应于进行所述PUSCH的NC-JT或C-JT,不同所述TCI关联的解调参考信号DMRS端口集合相同,其中,一个所述DMRS端口集合包括:一个或多个DMRS端口。
针对SFN传输的NC-JT或C-JT,每个TCI关联的DMRS端口集合可以相同,即每个天线面板在相同时域资源和频域资源下,采用SDM进行NC-JT或C-JT的DMRS端口相同。
以下结合上述任意实施例提供一个具体示例:
基于统一TCI架构(unified TCI framework)配置给终端适于同时传输的N个TCI state,根据MP/MTRP波束一致性是否成立,可以通过N个不同的联合TCI(joint TCI)或者N个独立上行TCI(separate UL TCI)共同指示给终端。这里N可以为2。即可以有两个TIC:TCI1和TCI2。每个TCI对应终端一个天线面板(panel)的发送/接收波束,并面向一个发送TRP方向。TCI各自包含不同的QCL Type-D source RS,终端使用TCI中包含的QCL Type-D source RS对应的天线面板进行接收。
没有配置统一TCI时,回退到3GPP release 15/16(R15/16)指示方案,使用SRI组合指示的spatialRelationInfo1/2。
对于每个TCI实际对应的数据传输层数的支持,需要考虑终端能力。根据终端上报的不同panel支持的最大SRS资源包含的最大端口数目,或最大支持的数据传输层(Layer)数量可能会有不同,即不同天线面板支持的最大数据传输层数目对应panel1和panel2分别为N_p1,N_p2。
基于单个DCI(S-DCI)的SDM传输,可以通过以下方案实现上行MTRP的NC-JT传输:
方案(Scheme)SDM-4:如图9所示,
1个TB的数据在同一时隙的相同时频资源上通过同一个数据传输层集合进行传输。多个TCI同时与1个数据传输层集合相关联。多个TCI同时与分配的对应一个DMRS端口或多个DMRS端口组相关联。其中,数据传输层集合包括一个或多个数据传输层。例如,TCI1和TCI2同时与一个数据传输层或多个数据传输层相关联,以及与分配的对应一个DMRS端口或多个个DMRS端口相关联;
通过单个RV实现单CW传输,编码后的比特在同一个数据传输层集合中进行传输。
每个TCI方向独立进行预编码处理,即每个天线面板/TRP方向使用的独立的预编码器(Precoder)。
支持的最大总传输层数:4层,实际不超过min{N_p1,N_p2}。N_p1,N_p2分别为终端两个天线面板支持的最大数据传输层数。
方案(Scheme)SDM-5:如图9所示,
1个TB的数据在同一时隙的相同时频资源上通过同一个数据传输层集合进行传输。多个TCI同时与1个数据传输层集合相关联。多个TCI同时与分配的对应一个DMRS端口或多个DMRS端口组相关联。其中,数据传 输层集合包括一个或多个数据传输层。例如,TCI1和TCI2同时与一个数据传输层或多个数据传输层相关联,以及与分配的对应一个DMRS端口或多个个DMRS端口相关联;
通过单个RV实现单CW传输,编码后的比特在同一个数据传输层集合中进行传输。
两个TCI方向联合进行预编码处理,即所有的天线面板/TRP发送数据在每个数据传输层均使用同一个预编码器(Precoder)。
支持的最大总传输层数:4层,实际不超过min{N_p1,N_p2}。N_p1,N_p2分别为终端两个天线面板支持的最大数据传输层数。
