Description

[根据细则37.2由ISA制定的发明名称] PUSCH传输配置方法及装置、通信设备及存储介质 技术领域
本公开涉及无线通信技术领域但不限于无线通信技术领域,尤其涉及一种物理上行共享信道(Physical Uplink Shared Channel,PUSCH)配置方法及装置、通信设备及存储介质。
背景技术
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,多点协作在新无线(New Radio,NR)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和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。每个发收点(Transmission Reception Point,TRP)的天线阵可以被分为若干相对独立的天线面板,因此整个阵面的形态和端口数都可以随部署场景与业务需求进行灵活的调整。
而天线面板或TRP之间也可以由光纤连接,进行更为灵活的分布式部署。
在毫米波波段,随着波长的减小,人体或车辆等障碍物所产生的阻挡效应将更为显著。
这种情况下,从保障链路连接鲁棒性的角度出发,也可以利用多个TRP或面板之间的协作,从多个角度的多个波束进行传输/接收,从而降低阻挡效应带来的不利影响。

请参考图1,其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统,该无线通信系统可以包括:若干个UE 11以及若干个接入设备12。
其中,UE 11可以是指向用户提供语音和/或数据连通性的设备。UE 11可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,UE 11可以是物联网UE,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment,UE)。或者,UE 11也可以是无人飞行器的设备。或者,UE 11也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线通信设备。或者,UE 11也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
接入设备12可以是无线通信系统中的网络侧设备。其中,该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication,4G)系统,又称长期演进(Long Term Evolution,LTE)系统;或者,该无线通信系统也可以是5G系统,又称新空口(new radio,NR)系统或5G NR系统。或者,该无线通信系统也可以是5G系统的再下一代系统。其中,5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。或者,MTC系统。
其中,接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者,接入设备12也可以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备12采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对接入设备12的具体实现方式不加以限定。
接入设备12和UE 11之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
如图2所示,本公开实施例提供一种PUSCH传输配置方法,其中,所述方法包括:
S1110:针对PUSCH的NC-JT,为终端的不同天线面板配置不同的TCI,且不同所述天线面板 采用FDM进行所述PUSCH的NC-JT。
该PUSCH传输配置为:针对具有两个或者两个以上天线面板的终端的PUSCH传输进行配置。
在一些实施例中,为终端的不同天线面板配置不同TCI的通信设备可为基站。
示例性地,该终端包括两个天线面板,终端的这两个天线面板的朝向可是相反的。一个所述天线面板上包括一个或多个天线振子。
在本公开实施例中,终端的不同天线面板可以用于向基站的不同TRP发送数据。
如图3所示,一个终端具有两个天线面板,可以向基站的TRP1和TRP2同时发送数据。
终端在执行PUSCH的NC-JT时,不需要进行多个天线面板发射的波束的联合赋形,每个天线面板可以独立对各自传输的数据流进行预编码,天线面板之间不需要相互协调相位。且终端在进行PUSCH的NC-JT时,数据流仅会映射到终端的部分天线面板上,无需映射到所有天线面板。
不同天线面板具有不同的TCI(即终端的不同天线面板配置有独立的TCI状态(state)),则不同天线面板的发射波束的波束方向是由各自对应的TCI单独指示的。
假设终端的两个天线面板执行PUSCH数据传输层数为4层,则图4所示的为终端的两个天线面板分别向TRP1和TRP2的C-JT,此时多个天线面板发送的数据传输层数相同,且需要传输每一个数据传输层。
在本公开实施例中,终端的不同天线面板采用FDM进行PUSCH的NC-JT,则天线面板使用的载波频率不同。
示例性地,终端的天线面板1使用频率1的载波,且终端的天线面板2使用频率2的载波。频率1不等于频率2,且示例性地,频率1和频率2之间具有一定频率间隔,从而使得天线面板同时收发信号的干扰降低,确保通信质量。
如图5所示为:以终端的两个天线面板的数据传输为例进行FDM。终端的一个天线面板使用波束1,另一个天线面板使用波束2;波束1和波束2的波束方向,分别由各自对应的TCI指示。在图5中纵轴为频域轴,横轴为时间轴。可见,波束1和波束2在时域使用相同的时域资源,且在频域使用不同的频域资源,实现基于FDM的PUSCH的NC-JT。示例性,波束1和波束2使用的时域资源可为一个或多个符号、一个或多个子时隙或者一个或多个时隙。
若终端的多个天线面板,根据各自对应的TCI,同时进行PUSCH的NC-JT传输,能够提升的通信系统的吞吐量,且提升传输可靠性。
天线面板对应的TCI、不同天线面板之间采用FDM进行PUSCH传输,且采用NC-JT进行PUSCH都属于前述PUSCH传输配置。
在一个实施例中,该终端被分配的频域资源可是连续的,即为同一个终端配置的RB可在频域连续分布。
在一个实施例中,所述PUSCH传输配置的一项或多项可由基站通过一个或多个网络信令发送给终端,也可以由网络协议预先约定上述PUSCH传输配置。
该网络信令包括但不限于:RRC信令、MAC CE和/或DCI。
在一些实施例中,不同所述TCI关联的时域资源相同且关联的频域资源不同。
在本公开实施例中,终端的不同天线面板采用FDM,再将终端不同天线面板的PUSCH的NC-JT配置在相同时域资源上,能够让终端的不同天线面板同时向基站的不同TRP发送数据,提升终端的传输带宽和发送速率。
在一个实施例中,一个所述TCI关联一个资源块RB集合,其中,一个所述RB集合包括:一个或多个RB。终端这种一个所述TCI关联一个资源块RB集合的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
在本公开实施例中,在进行PUSCH的NC-JT时,是以RB集合为频域资源调度的粒度。该RB集合最少包括一个RB。由于TCI与终端的天线面板具有对应关系,如此,TCI关联的RB集合,则相当于是将该RB集合配置给对应的天线面板。
在一些实施例中,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。终端这种不同所述TCI关联的数据传输层集合相同的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
采用NC-JT,则不同的天线面板可以不用关联到所有数据传输层,可以仅仅关联部分数据传输层。在本公开实施例中,一个TCI关联的数据传输层以集合的形式体现,则在对应的PUSCH传输配置中,该数据传输层集合可以以数据传输层集合的集合标识体现。一个数据传输层集合包括至少一个数据传输层。
在一些实施例中,不同所述TCI关联所述终端的一个解调参考信号(Demodulation of reference signal,DMRS)端口组合相同;
其中,一个所述DMRS端口组合包括所述终端的一个或多个DMRS端口。
终端这种TCI关联的DMRS端口组合的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
在本公开实施例中,采用NC-JT,则终端的多个TCI可以关联相同的DRMS端口组合。示例性地,此处一个DMRS端口组合包括的DMRS端口可为终端的部分或者全部端口。
示例性地,终端具有两个天线面板,且包括4个DMRS端口,则这两个天线面板对应的TCI均关联终端的第1至第3个DMRS端口。
在一些实施例中,进行所述NC-JT的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,所述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;所述x为小于或等于所述X的正整数。
由于采用PUSCH的NC-JC,终端的天线面板不用于进行联合赋形,则天线面板支持的最大数据传输层数可仅仅取决于该天线面板自身支持的最大数据传输层数。
示例性地,在进行PUSCH传输配置时,各个TCI关联的实际数据传输层数是根据该TC对应的天线面板支持支持的最大数据传输层数确定的。
终端这种天线面板和最大数据传输层数之间的关联关系的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
在一些实施例中,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NC-JT的单个TB传输,其中,一个所述TB对应于一个码字(Code Word,CW)。
终端这种不同天线面板使用单个冗余版本RV进行所述PUSCH的NC-JT的单个TB传输的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
不同天线面板关联单个RV,则终端进行PUSCH的NC-JC的多个天线面板对应的TCI可以关联相同的RV。
在一个实施例中,所述终端的多个天线面板使用单个调制与编码策略MCS通过不同所述天线面板实现所述PUSCH的NC-JT。
在本公开实施例中,多个天线面板使用相同的MCS进行PUSCH的NC-JT。若终端采用相同的MCS进行PUSCH的NC-JT,则基站侧可以采用相同的MCS进行PUSCH的NC-JT的接收数据的处理。
在一些实施例中,所述终端的频域资源在不同所述天线面板间均衡分配。
值得注意是:终端这种频域资源在不同所述天线面板间均衡分配的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
在本公开实施例中,所述终端的多个天线面板采用FDM进行PUCCH的NC-JT,此时FDM使用的频域资源数量分配方式有多种,其中一种为在多个天线面板之间进行均衡分配。若采用均衡分配,则终端的不同天线面板使用的频域资源数量是相等的。
具体地,终端的多个天线面板资源如何进行均衡分配时,单个天线面板的频域资源在频域连续分布的,或者,多个天线面板使用的频域资源在频域交错分布。
在一个实施例中,所述终端的使用多个冗余版本RV实现所述PUSCH的NC-JT的不同码字CW传输,其中,一个所述CW对应于一个传输块TB。
在一些实施例中,所述终端的多个天线面板使用多个MCS实现所述PUSCH的NC-JT。
值得注意是:终端这种多个天线面板使用多个MCS实现所述PUSCH的NC-JT的PUSCH传输配置,可以由基站通过网络信令配置或者终端根据协议约定配置。
当然不同天线面板使用多个MCS实现PUSCH的NC-JT,一种实现方式是:不同的天线面板可使用不同的MCS进行PUSCH的NC-JT;另一种实现方式是:不同天线面板使用相同的多个MCS进行PUSCH的NC-JT。若多个天线面板使用多个MCS进行PUSCH的NC-JC,则各天线面板对应的TCI关联的MCS的标识可为多个。
在一些实施例中,所述天线面板进行所述PUSCH的NC-JT的频域资源数量,与对应所述天线面板进行所述PUSCH的NC-JT的MCS具有关联关系。
在一些实施例中,针对所述PUSCH的NC-JT,多个所述天线面板使用的预编码矩阵独立。
天线面板进行PUSCH的NC-JT,则多个天线面板可以采用各自最适用的预编码矩阵进行预编码。
此时,不同天线面板对应的TCI,将关联各自的预编码矩阵的矩阵标识。

终端的多个天线面板(multi-panel)/基站的多个TRP(multi-TRP)的上行同时传输用于支持更高的吞吐率和更可靠的传输性能。
本公开实施例考虑如何基于单个(single)DCI调度的PUSCH传输或者免调度的PUSCH传输,以实现支持MP/MTRP的FDM传输方案定义和波束指示,具体方法如下:
考虑基于统一TCI框架(unified TCI framework)配置给终端适于同时传输的N个TCI的状态值(state)。
若MP/MTRP波束一致性成立,则可以通过N个不同的联合(joint)TCI指示终端的不同面板的TCI。
若MP/MTRP波束一致性不成立,则可以通过N个独立(separate)UL TCI共同指示给终端的PUSCH传输时各天线面板的TCI。
假设终端仅有两个天线面,即终端的天线面板个数N=2,则终端将被配置2个TCI,这里简化为TCI1和TCI2。
每个TCI对应终端一个天线面板的发送/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)。
终端使用TCI中包含的QCL Type-D source RS对应的天线面板收发。没有配置统一TCI框架时, 使用SRI组合指示的spatialRelationInfo1/2。
对于每个TCI实际对应的传输层数的支持,需要考虑终端能力,根据终端上报的不同天线面板支持的最大SRS资源包含的最大端口数目或最大支持的layer数目可能会有不同,即不同天线面板支持的最大layer数目对应天线面板1和天线面板2分别为N_p1,N_p2。
基于S-DCI的FDM传输,可以通过以下方案实现上行多个发收点(MTRP)的传输:
方式一:终端的多个天线面板基于FDM进行PUSCH的NC-JT的PUSCH传输配置,可如下:
1个TB的数据在同一时隙中不重叠的频域资源上进行映射传输,每个TCI与分配带宽内的1组RB集合相关联;每个时隙/符号上包含的TCI总数为N=2;
多个TCI对应一组DMRS端口或端口组合,支持的最大总数据传输层数为:4层。
实际配置的数据传输层数不超过min{N_p1,N_p2}。
使用单个RV实现单CW传输。
支持单个MCS;
在一种方式中,若使用单个MCS时,多个天线面板之间的频域资源均衡分配。
方式二:终端的多个天线面板基于FDM进行PUSCH的NC-JT的PUSCH传输配置,可如下:
1个TB通过2个CW在同一时隙中不重叠的频域资源上进行映射传输,每个TCI与分配带宽内的1组RB sets相关联;每个时隙/符号上包含的TCI总数为N=2;
多个TCI对应一组DMRS端口或端口组合,支持的最大总传输层数可为:4层,实际不超过min{N_p1,N_p2}。
多个天线面板使用多个RV实现多个CW的共同传输。多个天线面板使用多个RV实现多个CW的共同传输,可采用如下方式进行频域资源分配。
采用多MCS进行传输时,可以多个天线面板之间的频域资源可以均衡分配,也可以灵活调度。若多个天线面板的频域资源灵活调度时,多个天线面板之间的频域资源可以不均衡分配。
在本公开实施例中,考虑上行MP/MTRP同时传输情况下的不同增强方案,可以根据不同天线面板/TRP传输信道的实际质量分配DMRS端口,增加FDM传输方案下的灵活性,同时实现整体系统传输的可靠性和吞吐量的提升。
