为了更好的理解本申请实施例公开的一种基于多面板同时传输的上行通信方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1a，图1a为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1a所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备和两个或两个以上的终端设备。图1a所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(Long Term Evolution，LTE)系统、第五代移动通信系统、5G新空口系统，或者其他未来的新型移动通信系统等。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101和可以为演进型基站(Evolved NodeB，eNB)、传输点(Transmission Reception Point，TRP)、NR系统中的下一代基站(Next Generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(Wireless Fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(Central Unit，CU)与分布式单元(Distributed Unit，DU)组成的，其中，CU也可以称为控制单元(Control Unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(Mobile Station，MS)、移动终端设备(Mobile Terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(Mobile Phone)、物联网(Internet of Things，IoT)终端、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(Industrial Control)中的无线终端设备、无人驾驶(Self-Driving)中的无线终端设备、远程手术(Remote Medical Surgery)中的无线终端设备、智能电网(Smart Grid)中的无线终端设备、运输安全(Transportation Safety)中的无线终端设备、智慧城市(Smart City)中的无线终端设备、智慧家庭(Smart Home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
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)技术在NR(New Radio，新空口)系统中仍然是一种重要的技术手段。从保障链路连接鲁棒性的角度出发，也可以利用多个TRP(Transmission/Reception Point，传输/接收点)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。
根据发送信号流到多个TRP/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。
目前，Rel 18对于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)/物理上行控制信 道(Physical Uplink Control Channel，PUCCH)考虑基于多面板(panel)终端设备多个发送接收点(MultiTransmission and Reception Point，M-TRP)的同时传输增强。
也就是，主要是考虑在Multi-TRP场景下，利用多panel终端进行上行同时传输来提高上行速率，并进一步提高传输的可靠性。传输可以基于一个PDCCH信道承载的一个DCI进行调度，也可以考虑基于不同PDCCH承载的不同DCI分别调度。目前考虑的同步传输方案主要是不用Panel的信道发送基于空分复用(Space Division Multiplexing，SDM)或者频分复用(Frequency Division Multiplexing，FDM)来实现的。如图1b所示，图1b是本申请提供的一种基于单下行控制信息(Downlink Control Information，DCI；单DCI，single DCI，S-DCI)的多panel发送实现的逻辑示意图。
终端多panel实现一般会配置多个物理panel，不同的panel的能力可能也不相同，比如，该多个panel可能具备不同的探测参考信号(Sounding Reference Signal，SRS)端口数，或者该多个panel支持的最大数据传输层数也不一定相同，比如一个panel支持最大2层的传输，另一个panel支持最大4层的传输。网络调度器会判断终端当前是否适合多Panel的上行同时传输，如果终端当前适合多panel的上行同时传输同时被调度，则网络会直接或间接指示相关的传输参数，包括终端具体波束指示信息，传输使用的数据层数，以及使用的解调参考信号(Demodulation Reference Signal，DMRS)端口分配情况，以及预编码的指示信息等。在本申请各实施例中，主要需要确定在S-DCI调度下的DMRS端口指示问题，即如何确定不同panel上的PUSCH分别采用哪些DMRS端口来进行发送。其中，需要说明的是，对于NR系统中的数据信道(物理下行共享信道(PhysicalDownlink Shared Channel，PDSCH)/PUSCH)，数据传输的数据层与解调使用的DMRS端口相对应。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的基于多面板同时传输的上行通信方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种基于多面板同时传输的上行通信方法的流程示意图。需要说明的是，本申请实施例的基于多面板同时传输的上行通信方法由终端设备执行。该方法可以独立执行，也可以结合本申请任意一个其他实施例一起被执行。如图2所示，该方法可以包括如下步骤：
步骤201，接收网络设备发送的第一指示信息，该第一指示信息用于指示用于PUSCH传输的总的DMRS端口。
在本申请实施例中，该PUSCH传输是基于单下行控制信息(Downlink Control Information，DCI；单DCI，single DCI，S-DCI)的空分复用(Space Division Multiplexing，SDM)多天线面板同时传输(Simultaneous Transmission from Multiple Panels，STxMP)。
其中，需要说明的是，在Rel 18中，对于基于S-DCI的SDM上行STxMP方案包括：PUSCH的一个传输块(Transmission Block，TB)的不同部分分别通过不同panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的panel/TRP/传输时机(Transmission Occasion，TO)分别和不同的传输配置指示(Transmission Configuration Indication，TCI)状态(state)即波束相关联。
其中，PUSCH的TO是指PUSCH的一个传输块的不同数据层通过终端不同panel面向不同的TRP 在相同时频资源上进行发送，其中每个panel-TRP的传输链路上传输的部分PUSCH数据层对应一个PUSCH传输时机。
在本申请实施例中，终端设备能够接收网络设备发送的第一指示信息，该第一指示信息能够用于指示网络侧分配给用于PUSCH传输的总的DMRS端口。
在本申请各实施例中，该PUSCH的传输层数最大为4。
可选地，该第一指示信息可以为DCI。
进一步地，该第一指示信息可以为DCI中的天线端口(antenna ports)指示域。
需要说明的是，目前NR系统中对于数据信道(PUSCH/PDSCH)的DMRS设计主要包含以下几个方面：
(1)前置DMRS(front-loadDMRS)：在每个调度时间单位内，DMRS首次出现的位置应当尽可能地靠近调度的起始点。front-loadDMRS的使用，有助于接收侧快速估计信道并进行接收检测，对于降低时延并支持所谓的自包含结构具有重要的作用。取决于总共的正交DMRS端口数，front-loadDMRS最多可以占用两个连续的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
(2)附加DMRS(additionalDMRS)：对于低移动性场景，front-loadDMRS能以较低的开销获得满足解调需求的信道估计性能。但是，NR系统所考虑的移动速度动态范围很大，还需考虑高速移动的场景，除了front-loadDMRS之外，在中/高速场景之中，还需要在调度持续时间内安插更多的DMRS符号，以满足对信道时变性的估计精度。针对这一问题，NR系统中采用了front-load DMRS与时域密度可配置的additionalDMRS相结合的DMRS结构。每一组additionalDMRS的图样都是front-loadDMRS的重复。
在每个调度时间单位内，如果存在additionalDMRS，则每组additionalDMRS的图样均与front-loadDMRS保持一致。因此，front-loadDMRS的图样设计是DMRS设计的基础。front-load DMRS的设计思路分为两类，其中第一类(type1)是基于COMB(梳状码)+OCC(Orthogonal Cover Code，正交覆盖码)结构设计的，第二类(type2)是基于FDM+OCC结构设计的。
取决于传输所使用的正交端口数，front-loadDMRS最多可以配置为两个OFDM符号。考虑到功率利用效率的因素，使用两个符号的front-loadDMRS时，在频域CS或OCC基础之上，又在时域使用了TD-OCC(Time Domain-OCC，时域正交覆盖码)。
两种配置类型(configurationtype)的front-loadDMRS图样如图3a至3d所示。其中，图3a是配置类型为type1且时域上占用1个符号的DMRS图样示意图，图3b是配置类型为type1且时域上占用2个符号的DMRS图样示意图，图3c是配置类型为type2且时域上占用1个符号的DMRS图样示意图，图3d是配置类型为type2且时域上占用2个符号的DMRS图样示意图。
可以理解的是，图中占用相同时频域资源的DMRS端口需要通过码分复用来区分，属于同一个码分复用(Code Division Multiplexing，CDM)组。可见，如图3a所示的图样中，DMRS端口0,1属于同一个DMRS的CDM组，DMRS端口2,3属于同一个DMRS的CDM组。类似的，如图3b所示的图样中，DMRS端口0,1,4,5属于同一个DMRS的CDM组，DMRS端口2,3,6,7属于同一个DMRS的CDM组。如图3c所示的图样中，DMRS端口0,1属于同一个DMRS的CDM组，DMRS端口2,3属于同一个DMRS的CDM组，DMRS端口4,5属于同一个DMRS的CDM组。如图3d所示的图样中，DMRS端口0,1,6,7属于同一个DMRS的CDM组，DMRS端口2,3,8,9属于同一个DMRS的CDM组，DMRS 端口4,5,10,11属于同一个DMRS的CDM组。
在本申请实施例中，作为一种示例，上行带循环前缀的OFDM(CP-OFDM)波形下的不同参数配置的DMRS端口分配如下各表所示。可选地，第一指示信息可以为DCI中的一个指示域中的码点，不同的码点指示分配的不同DMRS端口(比如，在DMRS类型为1,前置DMRS占用的符号数量为1,且数据传输层数为2的情况下，第一指示信息取值为0用于指示分配给PUSCH的总的DMRS端口为编号为0和1的DMRS端口，且编号为0和1的DMRS端口属于同一个CDM组；再比如，在DMRS类型为1,前置DMRS占用的符号数量为1,且数据传输层数为3的情况下，第一指示信息取值为0用于指示分配给PUSCH的总的DMRS端口为编号为0,1,2的DMRS端口，且编号为0和1的DMRS端口属于同一个CDM组，编号为2的DMRS端口属于另一个CDM组)。
表1：DMRS类型dmrs-Type＝1,最大符号长度maxLength＝1,数据传输层数rank＝1
表2：dmrs-Type＝1,maxLength＝1,rank＝2
表3：dmrs-Type＝1,maxLength＝1,rank＝3
表4：dmrs-Type＝1,maxLength＝1,rank＝4

表6：dmrs-Type＝1,maxLength＝2,rank＝2
表7：dmrs-Type＝1,maxLength＝2,rank＝3
表8：dmrs-Type＝1,maxLength＝2,rank＝4
表9：dmrs-Type＝2,maxLength＝1,rank＝1
表10：dmrs-Type＝2,maxLength＝1,rank＝2
表11：dmrs-Type＝2,maxLength＝1,rank＝3

表12：dmrs-Type＝2,maxLength＝1,rank＝4
表13：dmrs-Type＝2,maxLength＝2,rank＝1

表14：dmrs-Type＝2,maxLength＝2,rank＝2
表15：dmrs-Type＝2,maxLength＝2,rank＝3
表16：dmrs-Type＝2,maxLength＝2,rank＝4
可以理解的是，上述各个表格中的每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表格中任何其他元素值。因此本领域内技术人员可以理解，该表格中的每一个元素的取值都是一个独立的实施例。
步骤202，接收该网络设备发送的第二指示信息，该第二指示信息用于指示该PUSCH的多个PUSCH传输时机分别对应的传输层数信息。
其中，该多个PUSCH传输时机是在多个TCI状态和/或TRP对应的方向上传输的。

传输预编码矩阵指示TPMI(Transmit Precoding Matrix Indicator)指示域；
发送接收点TRP；
用于指示波束的TCI状态。
在M-TRP传输中，支持两个SRS资源集合，因此在DCI中包含与两个SRS资源集合关联的两个SRI域，每个SRI指示域为一个TRP指示该SRI域关联的SRS资源集合中的SRS资源。两个SRI指示域会对应不同的PUSCH传输时机。可以通过SRS资源集合指示的指示域来动态指示单TRP和多TRP的传输调度。
在一些实施方式中，两个SRI/TPMI指示域中的第一SRI指示域或第一TPMI指示域对应的PUSCH传输时机的传输层数为R1，两个SRI/TPMI指示域中的第二SRI指示域或第二TPMI指示域对应的PUSCH传输时机的传输层数为R2，该第二指示信息能够用于指示该R1和R2。
其中，可以理解的是，在基于码本的PUSCH传输中，该PUSCH传输时机与SRI指示域对应，通过SRI指示域指示关联的SRS资源集合；在基于非码本的PUSCH传输中，该PUSCH传输时机与TPMI指示域对应，通过TPMI指示域指示关联的SRS资源集合。
在一些实施方式中，该第二指示信息可以分别指示该多个传输时机对应的传输层数信息，也可以组合指示该多个传输时机对应的传输层数的组合信息。

其中，该第一方向为第一TCI状态和/或第一TRP对应的方向，该第二方向为第二TCI状态和/或第二TRP对应的方向。
在本申请各实施例中，该第一指示信息和该第二指示信息可以为同一指示信息，也可以为不同的指示信息。
步骤203，确定各PUSCH传输时机对应的DMRS端口。
在本申请实施例中，终端设备能够确定各个PUSCH传输时机对应的DMRS端口。
在一些实施方式中，终端设备可以基于一个固定规则确定各个PUSCH传输时机对应的DMRS端口。
可选地，该固定规则可以为按照DMRS端口的编号的排序，确定各个PUSCH传输时机对应的DMRS端口。

综上，通过接收网络设备发送的第一指示信息，该第一指示信息用于指示用于物理上行共享信道PUSCH传输的总的解调参考信号DMRS端口，其中，该PUSCH传输是基于单下行控制信息DCI的空分复用SDM多天线面板同时传输STxMP，接收该网络设备发送的第二指示信息，该第二指示信息用于指示该PUSCH的多个PUSCH传输时机分别对应的传输层数RANK信息，其中，该多个PUSCH传输时机是在多个传输配置指示TCI状态和/或发送接收点TRP对应的方向上传输的，确定该各PUSCH传输时机对应的DMRS端口，能够灵活配置传输使用的DMRS端口，有效降低了多天线面板之间的传输干扰，有效提高传输的可靠性和鲁棒性，提高系统通信效率。

请参见图6，图6是本申请实施例提供的一种基于多面板同时传输的上行通信方法的流程示意图。需要说明的是，本申请实施例的基于多面板同时传输的上行通信方法由网络设备执行。该方法可以独立执行，也可以结合本申请任意一个其他实施例一起被执行。如图6所示，该方法可以包括如下步骤：
步骤601，向终端设备发送第一指示信息，该第一指示信息用于指示用于PUSCH传输的总的DMRS端口。
在本申请实施例中，该PUSCH传输是基于单DCI的空分复用SDM多天线面板同时传输STxMP。
其中，需要说明的是，在Rel 18中，对于基于S-DCI的SDM上行STxMP方案包括：PUSCH的一个传输块TB的不同部分分别通过不同panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的panel/TRP/传输时机分别和不同的TCI状态(state)即波束相关联。
其中，PUSCH的TO是指PUSCH的一个传输块的不同数据层通过终端不同panel面向不同的TRP在相同时频资源上进行发送，其中每个panel-TRP的传输链路上传输的部分PUSCH数据层对应一个PUSCH传输时机。
在本申请实施例中，终端设备能够接收网络设备发送的第一指示信息，该第一指示信息能够用于指示网络侧分配给用于PUSCH传输的总的DMRS端口。
在本申请各实施例中，该PUSCH的传输层数最大为4。
可选地，该第一指示信息可以为DCI。
进一步地，该第一指示信息可以为DCI中的天线端口(antenna ports)指示域。
在本申请实施例中，作为一种示例，上行带循环前缀的OFDM(CP-OFDM)波形下的不同参数配 置的DMRS端口分配可以如本申请前述实施例中的各个表格所示，在此不再赘述。
可选地，第一指示信息可以为DCI中的一个指示域中的码点，不同的码点指示分配的不同DMRS端口(比如，在DMRS类型为1,前置DMRS占用的符号数量为1,且数据传输层数为2的情况下，第一指示信息取值为0用于指示分配给PUSCH的总的DMRS端口为编号为0和1的DMRS端口，且编号为0和1的DMRS端口属于同一个CDM组；再比如，在DMRS类型为1,前置DMRS占用的符号数量为1,且数据传输层数为3的情况下，第一指示信息取值为0用于指示分配给PUSCH的总的DMRS端口为编号为0,1,2的DMRS端口，且编号为0和1的DMRS端口属于同一个CDM组，编号为2的DMRS端口属于另一个CDM组)。

在M-TRP传输中，支持两个SRS资源集合，因此在DCI中包含与两个SRS资源集合关联的两个SRI域，每个SRI指示域为一个TRP指示该SRI域关联的SRS资源集合中的SRS资源。两个SRI指示域会对应不同的PUSCH传输时机。可以通过SRS资源集合指示的指示域来动态指示单TRP和多TRP的传输调度。
在一些实施方式中，两个SRI/TPMI指示域中的第一SRI指示域或第一TPMI指示域对应的PUSCH传输时机的传输层数为R1，两个SRI/TPMI指示域中的第二SRI指示域或第二TPMI指示域对应的PUSCH传输时机的传输层数为R2，该第二指示信息能够用于指示该R1和R2。
其中，可以理解的是，在基于码本的PUSCH传输中，该PUSCH传输时机与SRI指示域对应，通过SRI指示域指示关联的SRS资源集合；在基于非码本的PUSCH传输中，该PUSCH传输时机与TPMI指示域对应，通过TPMI指示域指示关联的SRS资源集合。

在第二方向上传输的PUSCH传输时机与该第一SRI域或该第一TPMI域对应；
其中，该第一方向为第一TCI状态和/或第一TRP对应的方向，该第二方向为第二TCI状态和/或第二TRP对应的方向。
在一些实施方式中，该第二指示信息为SRS资源集合指示，该第二指示信息(SRS资源集合指示)包括的第一码点用于指示该传输层数为{R1，R2}的组合信息，其中，该传输层数为R1的PUSCH传输时机在第一方向上传输，该传输层数为R2的PUSCH传输时机在第二方向上传输；

在本申请各实施例中，该第一指示信息和该第二指示信息可以为同一指示信息，也可以为不同的指示信息。
在本申请实施例中，该各个PUSCH传输时机对应的DMRS端口是终端设备确定的。
在一些实施方式中，终端设备可以基于一个固定规则确定各个PUSCH传输时机对应的DMRS端口。
在一些实施方式中，终端设备能够判断该第一指示信息指示的DMRS端口是否属于同一个DMRS的CDM组。
可选地，在该第一指示信息指示的各个DMRS端口不属于同一个CDM组的情况下，确定第一PUSCH传输时机对应的第一DMRS端口以及第二PUSCH传输时机对应的第二DMRS端口，其中，该第一DMRS端口的端口数量等于该第一PUSCH传输时机对应的传输层数，该第二DMRS端口的端口数量等于该第二PUSCH传输时机对应的传输层数，且该第一DMRS端口属于同一CDM组，该第二DMRS端口属于另一CDM组。

综上，通过向终端设备发送第一指示信息，该第一指示信息用于指示用于物理上行共享信道PUSCH传输的总的解调参考信号DMRS端口，其中，该PUSCH传输是基于单下行控制信息DCI的空分复用SDM多天线面板同时传输STxMP，向该终端设备发送第二指示信息，该第二指示信息用于指示该PUSCH的多个PUSCH传输时机分别对应的传输层数RANK信息，其中，该多个PUSCH传输时机是在多个传输配置指示TCI状态和/或发送接收点TRP对应的方向上传输的，能够灵活配置传输使用的DMRS端口，有效降低了多天线面板之间的传输干扰，有效提高传输的可靠性和鲁棒性，提高系统通信效率。
