Description

频域资源分配方法及装置
本申请要求于2019年08月16日提交国家知识产权局、申请号为201910760494.6、申请名称为“频域资源分配方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种频域资源分配方法及装置。
背景技术
在新无线(new radio，NR)中，通过下行控制信息(downlink control information，DCI)中的频域资源分配(frequency domain resource allocation，FD-RA)指示域可以为终端设备指示分配的频域资源。
为了提高频谱利用率，在NR系统中，网络中的多个小区可以部署在相同的频段。该情况下，当终端设备处于小区的边缘时，终端设备的通信可能会受到服务小区的邻区发送的信号的干扰。为了解决该问题，可以通过多点传输技术有效地避免干扰，提高用户速率。其中，多点是指多个传输接收点(transmission reception point，TRP)，多个TRP可以通过交互信息，进行协作，从而避免干扰。
为了支持多点传输下的频域资源分配，一种较为普遍的做法为：通过同一个DCI中的FD-RA指示域指示不同TRP调度的资源，终端设备通过预设规则和DCI中的FD-RA指示域指示的资源确定不同的TRP中的每个TRP调度的资源。一种可能的实现方式，预设规则为奇偶分配原则，即奇数编号的资源块(resource block，RB)分配给TRP1，偶数编号的RB分配给TRP2，例如，参见图1中的(a)。另一种可能的实现方式，预设规则为前后均分原则，即RB编号的前一半分配给TRP1，RB编号的后一半分配给TRP2，例如，参见图1中的(b)。这两种频域资源分配方式，都可能会导致终端设备的信号接收质量下降。

具体实施方式
在本申请的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，“至少一个(份)”是指一个(份)或多个(份)，“多个(份)”是指两个(份)或两个(份)以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
本申请提供的技术方案所适用的通信系统中可以包括多个网络设备和至少一个终端设备，终端设备可以和多个网络设备通信。参见图2，终端设备可以处在多个网络设备(例如，网络设备1和网络设备2)的协作传输状态下，多个网络设备均可以向终端设备发送信令和下行数据，反之，终端设备也可以向多个网络设备发送上行数据。网络设备之间可以进行理想回传(ideal backhaul)，即网络设备之间基本没有交互时延，因此，多个网络设备与终端设备的协作传输可以通过同一个DCI调度，例如，由其中一个网络设备向终端设备发送调度多个网络设备的数据的DCI。
其中，本申请实施例中的通信系统包括但不限于长期演进(long term evolution，LTE)系统、第五代(5th-generation，5G)系统、NR系统，以及未来演进系统或者多种通信融合系统。其中，5G系统可以为非独立组网(non-standalone，NSA)的5G系统或独立组网(standalone，SA)的5G系统。
本申请实施例中的网络设备为网络侧的一种用于发送信号，或者，接收信号，或者，发送信号和接收信号的实体。网络设备可以为部署在无线接入网(radio access network，RAN)中为终端设备提供无线通信功能的装置，例如可以为TRP、基站、各种形式的控制节点(例如，网络控制器、无线控制器(例如，云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器))等。具体的，网络设备可以为各种形式的宏基站，微基站(也称为小站)，中继站，接入点(access point，AP)等，也可以为基站的天线面板。所述控制节点可以连接多个基站，并为所述多个基站覆盖下的多个终端设备配置资源。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，LTE系统中可以称为演进型基站(evolved NodeB，eNB或eNodeB)，5G系统或NR系统中可以称为下一代基站节点(next generation node base station，gNB)，本申请对基站的具体名称不作限定。网络设备还可以是未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等。
在一些部署中，网络设备可以包括集中式单元(centralized unit，CU)和分布式单元(Distributed Unit，DU)。网络设备还可以包括有源天线单元(active antenna unit，AAU)。CU实现网络设备的部分功能，DU实现网络设备的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)层，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PDCP层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，CU可以划分为RAN中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，在此不 做限制。
本申请实施例中的终端设备是用户侧的一种用于接收信号，或者，发送信号，或者，接收信号和发送信号的实体。终端设备用于向用户提供语音服务和数据连通性服务中的一种或多种。终端设备还可以称为用户设备(user equipment，UE)、终端、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。终端设备可以是移动站(mobile station，MS)、用户单元(subscriber unit)、无人机、物联网(internet of things，IoT)设备、无线局域网(wireless local area networks，WLAN)中的站点(station，ST)、蜂窝电话(cellular phone)、智能电话(smart phone)、无绳电话、无线数据卡、平板型电脑、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备(也可以称为穿戴式智能设备)。终端设备还可以为下一代通信系统中的终端设备，例如，5G系统中的终端设备或者未来演进的PLMN中的终端设备，NR系统中的终端设备等。
本申请实施例提供的技术方案可以应用于多种通信场景。例如，机器对机器(machine to machine，M2M)、宏微通信、增强型移动宽带(enhanced mobile broadband，eMBB)、超高可靠超低时延通信(ultra-reliable&low latency communication，URLLC)、车联网以及海量物联网通信(massive machine type communication，mMTC)等场景。
本申请实施例描述的网络架构以及业务场景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，随着网络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。
为了使得本申请实施例更加的清楚，以下对与本申请实施例相关的概念和部分内容作简单介绍。
1、准共址(quasi colocation，QCL)关系
准共址也可以称为准同位。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，所述参数可以包括以下一项或多项：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。
其中，上述角度可以为不同维度的分解值，或不同维度分解值的组合。天线端口为具有不同天线端口编号的天线端口，和/或，具有相同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口，和/或，具有不同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口。资源标识可以包括：信道状态信 息参考信号(channel state information reference signal，CSI-RS)资源标识，或探测参考信号(sounding reference signal，SRS)资源标识，或同步信号广播信道块(synchronous signal/physical broadcast channel block，可以简称为SS/PBCH block，也可以简称为SSB)资源标识，或物理随机接入信道(physical random access channel，PRACH)上传输的前导序列的资源标识，或解调参考信号(demodulation reference signal，DMRS)的资源标识，用于指示资源上的波束。
在NR协议中，QCL关系可以基于不同的参数分为以下四种类型：
类型A(type A)：多普勒频移、多普勒扩展、平均时延、时延扩展；
类型B(type B)：多普勒频移、多普勒扩展；
类型C(type C)：多普勒频移、平均时延；
类型D(type D)：空间接收参数。
其中类型为D的QCL用于指示不同的波束，即，基于空间接收参数定义的QCL。波束具有相同的空间特征，可以采用同一个接收波束来接收。波束在协议中具体地可以通过各种信号的标识来表示，例如CSI-RS的资源索引，SSB的索引，SRS的资源索引，跟踪参考信号(tracking reference signal，TRS)的资源索引。
2、第一传输方案、第二传输方案
在频分复用(frequency division multiplexing，FDM)的传输方式下，包括两种传输方案。为区分，分别记为第一传输方案和第二传输方案。以下以两个网络设备(例如两个TRP)分别向终端设备发送第一数据和第二数据为例，对第一传输方案和第二传输方案作简单介绍。
第一传输方案：
第一传输方案是指向终端设备发送同一份数据的不同部分的传输方案。此时，第一数据和第二数据分别为同一份数据的一部分，例如，第一数据为1000比特数据的前400个比特，第二数据为该1000比特数据的后600个比特。其中，一份数据可以认为是一个码字，一个码字可以认为由一个传输块(transport block，TB)生成。也就是说，第一数据和第二数据各自携带了一个TB的部分信息。可以理解，该第一数据和第二数据组成一个码字，且对应一个冗余版本(redundancy version，RV)。
在第一传输方案下，假设一个400bit的TB经过信道编码之后得到1000bit的数据，1000bit的数据需要分给两个TRP进行传输，为了提高传输效率，可以根据两个TRP当前的资源负载将1000bit的数据分给两个TRP，例如，可以给负载高的TRP分配400bit，给负载低的TRP分配600bit，为了适应两个TRP当前的负载，第一传输方案需要对应更加灵活的频域资源分配方式。
第一传输方案也可以称为FDM传输方案A或FDM方案2a。
第二传输方案：
第二传输方案是指向终端设备发送相同的多份数据的传输方案。此时，第一数据和第二数据为相同的数据。其中，相同的数据表示它们携带的TB信息是相同的。例如，第一数据对应一个TB，第二数据也对应一个TB，这两个TB为相同的TB。
这意味着第一数据和第二数据对应的码字可以由同一个TB生成，也可以分别由相同的两个TB生成，它们各自都携带了这个TB的全部信息。可以理解，第一数据和第二数据各 自对应一个码字，且各自对应一个RV，第一数据和第二数据各自对应的RV可以相同，也可以不同。
在第二传输方案下，同一个400bit的TB经过信道编码可以分别得到两个不同RV版本的1000bit的数据，映射到不同TRP所对应的时频资源上，为了确保调制与编码策略(modulation and coding scheme，MCS)相同或者接近，不同TRP的资源也要相同或接近，因此第二传输方案需要对应更加均匀的频域资源分配方式。
第二传输方案也可以称为FDM传输方案B或FDM方案2b。
在本文的描述中，关于TB、码字和数据的内容在此处做统一解释。网络设备首先会从高层收到一个TB，然后这个TB会经历一系列物理层流程，包括循环冗余校验(cyclic redundancy check，CRC)添加，码块(code bloc，CB)切割，基于CB的CRC添加，然后以CB为编码单位送进编码模块，并且进行速率匹配过程，在速率匹配过程中可以添加RV，从编码模块出来之后的CB可以再拼接成一串比特流，该比特流便是传统意义上的码字。码字经过调制便成了调制符号，将调制符号映射到物理信道的时频资源上，简称为数据。因此，一般意义上，TB和码字有一一对应关系，且一个码字只能添加一个RV。在本申请实施例中，当区分两个TRP发送的数据时，用第一数据、第二数据来描述，在这种语境下，数据也可以替换为TB或者码字。
3、多点传输技术
多点传输技术即多个TRP进行数据传输的技术。在多点传输技术中，多个TRP可以通过协作为用户发送下行信号，和/或，通过协作接收用户的上行信号。
多点传输技术主要分为联合传输(Joint transmission，JT)、动态点选择(dynamic point selection，DPS)、动态小区选择(dynamic cell selection，DCS)、协调波束成型(coordinated beam forming，CB)、协调调度(coordinated scheduling，CS)等。
本申请涉及到的多点传输主要是联合传输(或称为多点协作传输)场景，通过多个TRP的联合传输，能够提升处于小区边缘的终端设备的传输速率。示例性的，在非联合传输场景，参见图3中的(a)，当终端设备处于小区的边缘，终端设备的通信会受到服务小区的邻区发送的信号的干扰。图3中的(a)和图3中的(b)中，实线表示对终端设备产生的有用数据，虚线表示对终端设备产生的干扰。在联合传输场景，参见图3中的(b)，多个TRP联合给一个终端设备发送数据，终端设备收到多份有用数据，因此，服务小区的邻区发送的信号不仅不会对终端设备产生干扰，反而可以提升处于小区边缘的终端设备的传输速率。
4、多点协作的数据传输
5G及未来演进通信技术中，URLLC是重要业务类型之一。在URLLC业务中，数据吞吐量往往不再是主要的衡量指标，相比之下，低误码率和低时延成为最关键的指标。在多点传输技术中，多个TRP的信道之间存在信道多样性，采用多个TRP发送数据的方式可以提升通信链路的可靠性，因此多点传输技术可用于URLLC业务的可靠性增强。
具体的，多个TRP可以以频分的方式通过不同的信道向终端设备发送数据。示例性的，参见图4，终端设备处于TRP1和TRP2的联合传输场景下，TRP1和TRP2位于终端设备的不同方向，TRP1和TRP2可以采用上述第一传输方案或第二传输方案分别在频域资源1和频域资源2发送数据给同一个终端设备。其中，采用第一传输方案时，可以享受较低码率带来的编码增益，采用第二传输方案时，可以在终端设备做软合并带来额外的编码增益。此外， 两个TRP带来的空间分集增益可以使得两个TRP的信道全部处于信道深衰的可能性很低，从而提高数据传输可靠性。
5、系统带宽
在无线通信系统中，系统带宽又可以称为载波频率资源，或者载波单元(component carrier，CC)。系统带宽可以是一段连续的频域资源。网络设备可以从系统带宽中，为终端设备分配一段频域资源，以便于网络设备和终端设备之间可以利用被分配的频域资源进行通信。
6、部分带宽(bandwidth part，BWP)
BWP也可以称为载波带宽部分(carrier bandwidth part)。在频域，一个BWP中包括连续正整数个资源单元，比如包括连续正整数个子载波、资源块(resource block，RB)、或者资源块组(RB group，RBG)。BWP可以是下行BWP或者上行BWP。其中，上行BWP用于终端设备向网络设备发送信号，下行BWP用于网络设备向终端设备发送信号。在本申请实施例中，正整数个可以是1个、2个、3个或者更多个，本申请实施例对此不做限制。
终端设备可以配置有多个BWP。针对每个BWP，可以通过预配置或者网络设备向终端设备发送信令的方式，独立配置该BWP的参数集(numerology)。不同BWP的numerology可能相同，也可能不同。numerology可以通过但不限于以下参数信息中的一种或多种定义：子载波间隔，循环前缀(cyclic prefix，CP)、时间单位的信息、BWP的带宽等。例如，numerology可以由子载波间隔和CP来定义。
7、RB
RB是最基本的资源单位之一，在频域上，一个RB可以包括正整数个子载波，例如6个或12个。RB的定义还可以扩展到时域，例如：一个RB在时域上包括正整数个时域符号。示例性的，一个RB在频域上包括12个子载波，在时域上包括7或14个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。
在进行频域资源分配的时候，RB还会进一步区分为物理资源块(physical resource block，PRB)或虚拟资源块(virtual resource block，VRB)。通过DCI中的FD-RA指示域分配频域资源的时候，FD-RA指示域所指示的频域资源为VRB，数据也是首先映射到VRB上。而后一个步骤，是从VRB到PRB的映射，在这个步骤中，如果没有频域交织，则VRB与PRB的编号一一对应，例如编号为n的VRB上的数据，会映射到编号为n的PRB上，示例性的，可参见图5；如果经历频域交织，则VRB和PRB的编号在当前BWP带宽内可以错序映射，例如，编号为n的VRB上的数据，可能会映射到编号为n+K的PRB上，示例性的，可参见图6。这里n为大于等零的整数，K为整数。具体交织规则可参考现有技术，在此不再赘述。
本申请实施例若无特别说明，RB既可以指VRB，也可以指PRB。若与其他信息一起描述时，可根据具体场景判断为VRB还是PRB。例如，描述RBG时，如无特殊说明，默认RBG由连续的多个VRB组成。再例如，描述PRG时，如无特殊说明，默认PRG由连续的多个PRB组成。
8、资源块组(resource block groups，RBG)
RBG包括一组连续的VRB。RBG中包含的VRB的个数即RBG的大小(RBG size)。例如，RBG size为2，则一个RBG包括连续的2个VRB。目前，NR协议中RBG size可以为2、4、8、16等。
对于终端设备来说，RBG size可根据RBG配置以及BWP带宽来确定。目前，NR标准预定义了两种RBG配置。在RBG配置1中，RBG size的候选值为2、4、8、16；在RBG配置2中，RBG size的候选值为4、8、16。网络设备可通过高层信令参数rbg-Size来向终端设备指示每个BWP中的RBG配置。
示例性的，RBG size与RBG配置、BWP带宽的关系可参考表1，BWP带宽即BWP所包含的RB的个数。
表1
BWP带宽 RBG配置1 RBG配置2
1-36 2 4
37-72 4 8
73-144 8 16
145-275 16 16
9、BWP中RBG的个数以及大小
RBG的划分是按照系统带宽进行划分的，即，第一个RBG由系统带宽起始的P个RB组成，依次类推，P为RBG size。具体如图7所示，当P＝2时，从RB0开始，每2个RB组成一个RBG，其中RB0为系统带宽中编号最小的RB。
BWP是由起始RB(即第一个RB)和RB长度定义的一段连续的频域资源。BWP中的起始RB和结束RB均可以为系统带宽中的任何RB。因此，起始RB或结束RB所属的RBG中的RB可能一部分位于BWP内，另一部分位于BWP外。例如图7所示，BWP的起始RB为RB3，RB2和RB3本来是属于同一个RBG的，但是RB3在BWP内，RB2在BWP外。BWP的结束RB为RB12，RB12和RB13本来是属于同一个RBG的，但是RB3在BWP内，RB13在BWP外。
因此，BWP内RBG的个数和大小的计算方法如下所示：
一个BWP包含的RBG的总数为：

其中，

Figure PCTCN2020109385-appb-000023

其中，第1个RBG(编号为0)的大小为
Figure PCTCN2020109385-appb-000024
针对最后一个RBG(编号为N RBG-1)，若
Figure PCTCN2020109385-appb-000025
最后一个RBG的大小为：

若

最后一个RBG的大小为：
Figure PCTCN2020109385-appb-000029
其余的RBG的大小均为P。
BWP中包含的N RBG个RBG的编号从0到N RBG-1，也可以从1到N RBG或采用其他方式编号，本文中以0到N RBG-1为例进行说明。
示例性的，参见图7，BWP中起始RB在系统带宽中的编号为3，RBG的大小为2，BWP中包含10个RB，则BWP中包含的RBG个数：
Figure PCTCN2020109385-appb-000030

其中，第一个RBG(即RBG0)的大小为：
Figure PCTCN2020109385-appb-000032
Figure PCTCN2020109385-appb-000033
最后一个RBG(即RBG5)的大小为：
Figure PCTCN2020109385-appb-000034
Figure PCTCN2020109385-appb-000035
其余RBG的大小均为2。
10、预编码资源组(precoding resource group，PRG)
一个PRG包括多个连续的PRB，每个PRG中的PRB上的数据采用相同的发送预编码矩阵进行预编码。PRG中包含的PRB的个数可以称为PRG的大小(PRG size)。目前，NR协 议中PRG size可以为2、4或全带宽(wideband)。
此外，终端设备可以假设网络设备采用相同的发送预编码矩阵发送同一个PRG中的PRB上的数据。
PRG的划分同样是按照系统带宽划分的，因此，BWP内PRG的个数和各个PRG的大小的计算方法与BWP内RBG的个数和各个RBG的大小的计算方法类似，只需要将公式中的P替换为PRG size即可，在此不再赘述。
11、交织资源单元
交织资源单元是指进行频域交织的资源单元，即RB bundles，具体可以为VRB bundles或PRB bundles。一个交织资源单元由多个连续的RB组成。一个交织资源单元所包含的RB的个数称为交织资源单元的大小(即bundle size)。例如，bundle size可选取值为2或4。
当VRB通过频域交织映射到PRB时，以交织资源单元为单位进行映射，即一个交织资源单元所包含的连续的VRB，映射到PRB时，也保持连续的状态。
交织资源单元的划分同样是按照系统带宽划分的，因此，BWP内交织资源单元的个数和各个交织资源单元的大小的计算方法与BWP内RBG的个数和各个RBG的大小的计算方法类似，只需要将公式中的P替换为Bundle size即可，在此不再赘述。
12、测量带宽
在进行数据传输之前，网络设备会向终端设备发送CSI-RS，终端设备根据接收到的CSI-RS进行信道测量并向网络设备反馈信道状态信息(channel state information，CSI)，CSI可以包括预编码矩阵(precoding matrix indicator，PMI)，信道质量指示(channel quality indicator，CQI)、秩指示(rank indication，RI)等。在进行信道测量之前，网络设备给终端设备配置CSI-RS资源，并配置上报格式和测量带宽。其中，配置的测量带宽可以是全带(即整个BWP)，也可以是子带(subband)。当为全带时，终端设备在整个测量带宽(即BWP)进行信道测量后上报一份CSI。当为测量子带时，意味着整个测量带宽被分为多个测量子带，针对每个测量子带可以上报一份CSI。其中，测量子带的大小和BWP带宽的关系可参考表2。其中，测量子带的大小即测量子带包含的RB的个数。
表2
BWP带宽 测量子带的大小
<24 无
24-72 4,8
73-144 8,16
145-275 16,32
信道测量的测量子带的划分同样是按照系统带宽划分的，因此，BWP内测量子带的个数和各个测量子带的大小的计算方法与BWP内RBG的个数和各个RBG的大小的计算方法类似，只需要将公式中的P替换为测量子带大小即可，在此不再赘述。
13、现有的频域资源分配类型
现有的频域资源分配类型有两种：类型0(Type0)和类型1(Type1)。
频域资源分配Type0中，DCI中的FD-RA指示域由一个位图(bitmap)组成，bitmap中的1个bit用于向终端设备指示一个RBG是否被分配用于进行数据传输。Bitmap的长度等于BWP范围内RBG的数量(记为N RBG)，以此达到以RBG为颗粒度的传输带宽的灵活指示。 基于图7所示的示例，Bitmap中可以包括6个bit，6个bit中一个bit用于指示6个RBG中的一个RBG是否被分配用于进行数据传输。另外，在某些情况下，系统可能会配置一个动态指示比特来指示FD-RA采用的是Type0还是Type1，此时这个指示比特作为最高有效位(most significant bit，MSB)放在整个bitmap的开头，即此时FD-RA指示域的长度为N RBG+1。
频域资源分配Type1中，FD-RA指示域由一个资源指示值(resource indication value，RIV)组成，RIV是根据一个确定的公式计算出来的一个值，公式的输入有起始VRB编号和连续VRB的长度，不同的起始VRB编号和连续VRB长度的组合计算获得的RIV值不同。在Type1类型中，RIV指示一段连续的VRB。示例性的，参见图8。RIV指示的资源可以为VRB5至VRB11。
为了支持多点传输，分配给终端设备的频域资源可能需要划分为多份，分别分配给不同的TRP调度。根据背景技术中提到的现有的频域资源分配的方式，一个PRG内的资源有可能分配给不同的TRP，由于处于协作中的TRP往往处在同一个终端设备的不同的方向，其各自到终端设备的信道是不同的，因此基于信道测量的结果，不同TRP一般会采用不同的发送预编码矩阵发送数据，然而终端设备则始终会默认同一个PRG内的PRB上的数据是通过相同的发送预编码矩阵进行预编码后发送的，因此终端设备也会采用同一个信道均衡矩阵解多流数据，此时，发送方和接收方的假设不一致，导致发送预编码矩阵和信道均衡矩阵之间不匹配，从而会导致信号接收质量下降。
为了解决该问题，本申请实施例提供了一种频域资源分配方法。
针对终端设备，参见图9，该方法包括：
901、终端设备根据预定频域资源分配规则确定M份频域资源，M为大于1的整数。
步骤901在具体实现时，终端设备可以根据预定频域资源分配规则和预定带宽确定M份频域资源。关于频域资源分配的具体描述参见下文。
902、终端设备在M份频域资源中的一份或多份频域资源接收数据。
针对网络设备(记为第一网络设备)，参见图10，该频域资源分配方法包括：
1001、第一网络设备确定终端设备的上述预定带宽。
1002、第一网络设备根据上述预定频域资源分配规则和上述预定带宽分配上述M份频域资源。
在步骤1002之后，在不同的场景下，第一网络设备执行的动作可以不同，以下具体进行描述。
场景1、第一网络设备的M个TRP通过协作向终端设备发送数据。
在场景1下，示例性的，第一网络设备可以为基站，TRP可以为基站的天线面板。
在场景1下，M个TRP与M份频域资源一一对应，在步骤1002之后，第一网络设备可以通过M个TRP分别对应的频域资源向终端设备发送数据。第一网络设备可以通过M个TRP采用第一传输模式向终端设备发送数据，也可以采用第二传输模式向终端设备发送数据。
场景2、不包括第一网络设备在内的M个网络设备通过协作向终端设备发送数据。
在场景2下，第一网络设备可以具有集中调度功能。第一网络设备和M个网络设备可以均为基站，也可以均为TRP。
在场景2下，M个网络设备与M份频域资源一一对应，在步骤1002之后，第一网络 设备向M个网络设备发送对应的频域资源的信息，M个网络设备在对应的频域资源上向终端设备发送数据。M个网络设备可以采用第一传输模式向终端设备发送数据，也可以采用第二传输模式向终端设备发送数据。
场景3、包括第一网络设备在内的M个网络设备通过协作向终端设备发送数据。
在场景3下，第一网络设备可以为M个网络设备中的具有集中调度功能的网络设备。M个网络设备可以均为基站，也可以均为TRP。
在场景3下，M个网络设备与M份频域资源一一对应，在步骤1002之后，第一网络设备向M个网络设备中的除第一网络设备之外的M-1个网络设备发送对应的频域资源的信息，M个网络设备在对应的频域资源上向终端设备发送数据。M个网络设备可以采用第一传输模式向终端设备发送数据，也可以采用第二传输模式向终端设备发送数据。
以下对上述频域资源分配的具体过程作详细阐述。
上述频域资源分配方法中，终端设备根据预定频域资源分配规则和预定带宽可以确定M份频域资源。相应的，第一网络设备根据预定频域资源分配规则和预定带宽可以分配M份频域资源。M份频域资源中的任意两份频域资源不重叠，M份频域资源各自关联一个QCL信息，M份频域资源中的任意两份频域资源关联的QCL信息不同。例如，图11中的(a)中的2份频域资源可以各自对应一个QCL信息、且2份频域资源对应的QCL信息不同。图11中的(b)中，3份频域资源可以各自对应一个QCL信息、且3份频域资源对应的QCL信息均不同。M份频域资源中的不同份的频域资源中包含的RB的个数可以相同也可以不同。例如，图11中的(b)中，第1份频域资源和第2份频域资源包含的RB的个数相同，第1份频域资源和第3份频域资源包含的RB的个数不同。
预定频域资源分配规则可以为预设的或通过信令配置给终端设备的或协议规定的，本申请对终端设备获取预定频域资源分配规则的方法不作限定。其中，频域资源分配规则可以为交替分配规则，即从预定带宽中的起始RB开始，按照RB编号升序的方向，以频域资源分配单元为单位依次分配给第1份频域资源至第M份频域资源，若分配至第M份频域资源之后，还有剩余的频域资源分配单元，则再依次分配给第1份频域资源至第M份频域资源，以此类推。例如，参见图11中的(a)，示例性的从RB0开始，以连续的2个RB为单位进行频域资源分配，则RB0和RB1分配给第1份频域资源，RB2和RB3分配给第2份频域资源，RB4和RB5再分配给第1份频域资源，RB6和RB7再分配给第2份频域资源，依次类推，则一份频域资源包括的RB不全是连续的，即有些RB之间是连续的，有些RB之间是不连续的。再例如，参见图11中的(b)，示例性的从RB0开始，以连续的6个RB进行频域资源分配，其中，RB0至RB5分配给第1份频域资源，RB6至RB11分配给第2份频域资源，RB12至RB15分配给第3份频域资源，此时，任一份频域资源包括的RB全是连续的。可以理解的是，图11中的(a)和图11中的(b)进行频域资源分配的方法是一样的，即交替地分配，导致频域资源分配结果不同的原因在于频域资源分配单元的粒度不同。其中，图11中的(a)中是以连续的2个RB为单位进行频域资源分配的，而图11中的(b)中是以连续的6个RB为单位进行分配的。如上所述的交替分配规则，也可以称为梳状分配规则，交错分配规则或交织分配规则，本申请实施例对分配规则的名称不做限定。
如前述在为多个TRP分配频域资源时，为了确保同一个PRG内的PRB不会被同时分 配给不同的TRP，本申请提出频域资源分配单元的最小粒度，该最小粒度为x个连续的RB(连续的VRB或连续的PRB)，x的取值为PRG size。应理解，PRG size是一个可配值，因此频域资源单元的最小粒度也会随PRG size的变化而变化。
可选的，频域资源分配单元的粒度除了可以为该最小粒度之外，还可以为其他粒度，例如，下文中的RBG、交织资源单元等，具体可参见下文中的相关描述。但是，当频域资源分配单元的粒度为其他粒度时，其不能小于最小粒度，即不能小于PRG size。
应理解，当PRG size配置为wideband时，这里的wideband不再指向整个预定带宽，而是指向一份频域资源，即终端设备根据PRG size配置为wideband，可以假设在M份频域资源中的任一份频域资源上，TRP在该份频域资源上所采用的发送预编码矩阵相同。
在进行频域资源分配时，是在预定带宽中进行的，预定带宽可以为BWP或系统带宽或调度带宽。预定带宽不同时，频域资源分配的过程也有所不同，以下通过情况1(预定带宽为BWP)、情况2(预定带宽为系统带宽)和情况3(预定带宽为调度带宽)分别进行描述。
情况1、预定带宽为BWP
在情况1下，频域资源分配可以基于BWP内的所有频域资源，即频域资源分配是从BWP内的第一个频域资源分配单元开始，直到该BWP内的最后一个频域资源分配单元结束。
在情况1下，当PRG size未被配置为wideband时，x的值与PRG size相同。例如，PRG size配置为2时，x为2。PRG size配置为4时，x为4。此时，频域资源分配单元可以为RBG或PRG或交织资源单元或y(y为x的k倍，k为正整数)个连续的RB或信道测量的测量子带。与RBG类似的，频域资源分配单元的划分也是按照系统带宽进行划分的，因此，BWP中的频域资源分配单元的个数以及各个频域资源分配单元大小的计算方法与BWP中的RBG的个数以及各个RBG大小的计算方法类似。
具体的，若将频域资源分配单元大小记为Q，则一个BWP包含的频域资源分配单元的总数为：
Figure PCTCN2020109385-appb-000036
其中，
Figure PCTCN2020109385-appb-000037
为BWP所包含的RB的数目，
Figure PCTCN2020109385-appb-000038
为BWP中的起始RB在系统带宽上的编号，mod为取余函数。
其中，第1个频域资源分配单元(编号为0)的大小为：
Figure PCTCN2020109385-appb-000039
针对最后一个频域资源分配单元(编号为N-1)，若
Figure PCTCN2020109385-appb-000040
最后一个频域资源分配单元的大小为：
Figure PCTCN2020109385-appb-000041
若
Figure PCTCN2020109385-appb-000042
最后一个频域资源分配单元的大小为Q。其余的频域资源分配单元的大小均为Q。
BWP中包含的N个频域资源分配单元的编号从0到N-1，也可以从1到N或采用其他方式编号，本文中以0到N-1为例进行说明。示例性的，参见图11A，BWP中起始RB在系统带宽中的编号为3，频域资源分配单元的大小为2，BWP中包含10个RB，则BWP中包含的频域资源分配单元个数：
Figure PCTCN2020109385-appb-000043
其中，第一个频域资源分配单元(即频域资源分配单元0)的大小为：
Figure PCTCN2020109385-appb-000044
Figure PCTCN2020109385-appb-000045
最后一个频域资源分配单元(即频域资源分配单元5)的大小为：
Figure PCTCN2020109385-appb-000046
其余频域资源分配单元的大小均为2。
在情况1下，当PRG size被配置为wideband时，x为
Figure PCTCN2020109385-appb-000047
W为终端设备的BWP中包含的RB的个数。此时，频域资源分配单元可以为x个连续的RB。也就是说，在RB为PRB的情况下，当PRG的大小为全带宽时，以
Figure PCTCN2020109385-appb-000048
个PRB为频域资源分配单元确定M份频域资源。
具体的，当PRG的大小为全带宽时，M份频域资源中的第m份频域资源包括BWP中第
Figure PCTCN2020109385-appb-000049
个PRB至第
Figure PCTCN2020109385-appb-000050
个PRB，M份频域资源中的第M份频域资源包括BWP中的剩余的PRB，m为大于0小于M的整数。其中，
Figure PCTCN2020109385-appb-000051
是指
Figure PCTCN2020109385-appb-000052
是指
Figure PCTCN2020109385-appb-000053
“*”表示“乘以”。
该情况下，频域资源分配单元的划分是按照BWP进行划分的，从BWP的起始RB开始，每x个连续的RB为一个频域资源分配单元。其中，由于W不一定是M的整数倍，因此，最后一个频域资源分配单元的大小可以是小于x的。示例性的，假设BWP中包括16个RB，M＝3，则x＝6，参见图12，BWP中可以包括3个频域资源分配单元，其中，频域资源分配单元0和频域资源分配单元1的大小均为6，频域资源分配单元2的大小为4。
在情况1下，频域资源分配方法可以为：终端设备确定M份频域资源中的第m份频域资源，第m份频域资源包括终端设备的BWP中包括的N个频域资源分配单元中的第Mi+m个频域资源分配单元。相应的，第一网络设备将终端设备的BWP中包括的N个频域资源分配单元中的第Mi+m个分配给M份频域资源中的第m份频域资源。其中，N为正整数，m为大于0小于等于M的整数，
Figure PCTCN2020109385-appb-000054
该种交替频域资源分配方法，可以使得多份频域资源尽量离散地分布在BWP上，从而获得更好的频域分集增益。其中，Mi是指M*i。
示例性的，参见图13中的(a)和图13中的(b)。BWP中包括5个频域资源分配单元。若M＝2，则参见图13中的(a)，5个频域资源分配单元中的频域资源分配单元0、频域资源分配单元2和频域资源分配单元4为第1份频域资源，频域资源分配单元1和频域资源分配单元3为第2份频域资源。若M＝3，则参见图13中的(b)，5个频域资源分配单元中的频域资源分配单元0和频域资源分配单元3为第1份频域资源，频域资源分配单元1和频域资源分配单元4为第2份频域资源，频域资源分配单元2为第3份频域资源。
在频域资源分配类型不同时，频域资源分配单元也有所不同，以下通过情况1.1(频域资源分配类型为Type0)、情况1.2(频域资源分配类型为Type1)对不同频域资源分配单元下频域资源分配的过程作示例性说明。
情况1.1、Type0
情况1.1又可以分为以下情况1.1.1和情况1.1.2。
情况1.1.1、PRG size未被配置为wideband。
此时，频域资源分配单元可以为以下4种。
(1)PRG
示例性的，假设PRG size＝2，M＝2，参见图14，PRG0至PRG5中的PRG0、PRG2和PRG4组成第1份频域资源，PRG1、PRG3和PRG5组成第2份频域资源。
(2)RBG
需要说明的是，PRG size总是小于等于RBG size，RBG size可以为PRG size的整数倍。
当频域资源分配单元为RBG、且RBG size＝PRG size时，频域资源分配的过程与频域资源分配单元为PRG时是类似的，所得到的分配结果也是相同的，区别仅在于前者是作用在VRB域，而后者是作用在PRB域的。
当频域资源分配单元为RBG、且RBG size>PRG size时，示例性的，假设RBG size＝4，PRG size＝2，M＝2，参见图15，RBG0至RBG3中的RBG0和RBG2组成第1份频域资源， RBG1和RBG3组成第2份频域资源。
若频域资源分配单元为RBG，上述频域资源分配的方法也可以认为是：终端设备确定的第m份频域资源包括bitmap中的第Mi+m个比特对应的频域资源。示例性的，当M＝2时，终端设备可以将bitmap中的偶数位的比特对应的频域资源确定为一份频域资源，将bitmap中的奇数位的比特对应的频域资源确定为另一份频域资源。
(3)y个连续的RB
此处RB可以为VRB，也可以为PRB。
y可以等于PRG size或RBG size。当y＝PRG size时，频域资源分配的过程与频域资源分配单元为PRG时是类似的，所得到的分配结果也是相同的。当y＝RBG size时，频域资源分配的过程与频域资源分配单元为RBG时是类似的，所得到的分配结果也是相同的。
y也可以不等于PRG size或RBG size，例如，PRG size＝2，RBG size＝4时，y可以等于6或8等。假设y＝6，M＝2，参见图16，6个连续的RB为1个频域资源分配单元，则频域资源分配单元0至频域资源分配单元3中的频域资源分配单元0和频域资源分配单元2组成第1份频域资源，频域资源分配单元1和频域资源分配单元3组成第2份频域资源。
(4)信道测量的测量子带
该情况下，频域资源分配的过程可以作用在VRB域也可以作用在PRB域。
频域资源分配单元为信道测量的测量子带时，频域资源分配的过程与频域资源分配单元为RBG、PRG和y个连续的RB时的频域资源分配过程是类似的。例如，若一种场景为测量子带包括4个VRB时，将图15中的RBG替换为测量子带则可以得到该场景下的频域资源分配的示例。具体可参照上文进行理解，不再赘述。
其中，信道测量的测量子带可以根据最近一次的CSI上报所配置的测量子带确定。频域资源分配单元为测量子带时，可以确保任何一个经过信道测量反馈后的测量子带被完整的分配给一个网络设备(例如，TRP)，从而简化终端设备的测量负担。例如，在信道测量之前便将不同的测量子带分配给不同的网络设备，则终端设备只需要针对某一个网络设备进行一次信道测量。否则，终端设备就可能需要针对所有的网络设备分别进行多次信道测量。
情况1.1.2、PRG size被配置为wideband。
情况1.1.2下，频域资源分配的过程可以作用在VRB域也可以作用在PRB域。
情况1.1.2下，频域资源分配单元为x个连续的RB、且频域资源分配单元的划分是按照BWP进行划分的。示例性的，基于图12所示的示例，假设M＝2，则BWP中的3个频域资源分配单元中的频域资源分配单元0和频域资源分配单元2组成第1份频域资源，频域资源分配单元1组成第2份频域资源。
情况1.1.2下，一份频域资源中的全部的频域资源上的数据采用相同的发送预编码矩阵进行预编码。相应的，针对同一个PRG内的PRB上的数据，终端设备采用同一个信道均衡矩阵解多流数据。
情况1.2、Type1
情况1.2又可以分为以下情况1.2.1和情况1.2.2。
情况1.2.1、PRG size未被配置为wideband。
此时，频域资源分配单元可以为以下4种。
(1)PRG
当频域资源分配单元为PRG时，频域资源分配过程与情况1.1.1中频域资源分配单元为PRG时的情况是相同的，可参见上文，不再赘述。此时，VRB和PRB之间可以进行频域交织，也可以不进行频域交织。
(2)y个连续的RB
当频域资源分配单元为y个连续的RB时，频域资源分配过程与情况1.1.1中频域资源分配单元为y个连续的RB时的情况是相同的，可参见上文，不再赘述。此时，VRB和PRB之间可以进行频域交织，也可以不进行频域交织。
(3)信道测量的测量子带
当频域资源分配单元为信道测量的测量子带时，频域资源分配过程与情况1.1.1中频域资源分配单元为信道测量的测量子带时的情况是相同的，可参见上文，不再赘述。此时，VRB和PRB之间可以进行频域交织，也可以不进行频域交织。
(4)资源交织单元
该情况下，VRB和PRB之间进行频域交织。根据上文可知，资源交织单元可以为VRB bundles或PRB bundles。
当资源交织单元为VRB bundles时，假设bundle size＝2，M＝2，参见图17，交织资源单元0至交织资源单元5中的交织资源单元0、交织资源单元2和交织资源单元4组成第1份频域资源，交织资源单元1、交织资源单元3和交织资源单元5组成第2份频域资源。其中，各个交织资源单元映射到的PRB可参见图17。假设bundle size＝4，M＝2，参见图18，交织资源单元0至交织资源单元3中的交织资源单元0和交织资源单元2组成第1份频域资源，交织资源单元1和交织资源单元3组成第2份频域资源。其中，各个交织资源单元映射到的PRB可参见图18。
当资源交织单元为PRB bundles时，假设bundle size＝2，M＝2，参见图19，交织资源单元0至交织资源单元5中的交织资源单元0、交织资源单元2和交织资源单元4组成第1份频域资源，交织资源单元1、交织资源单元3和交织资源单元5组成第2份频域资源。假设bundle size＝4，M＝2，参见图20，交织资源单元0至交织资源单元3中的交织资源单元0和交织资源单元2组成第1份频域资源，交织资源单元1和交织资源单元3组成第2份频域资源。
情况1.2.2、PRG size被配置为wideband。
情况1.2.2下频域资源分配的过程与情况1.1.2是相同的，可参见上文，不再赘述。
情况1下，第一网络设备或终端设备所分配的频域资源并不一定全部被分配用于进行数据传输，具体用于进行数据传输的频域资源还需要通过DCI中的bitmap或RIV指示。该情况下，各个网络设备(例如，上述M个网络设备)在M份频域资源中的被分配用于进行数据传输的频域资源上发送数据，相应的，终端设备在M份频域资源中的被分配用于进行数据传输的频域资源上接收数据。示例性的，参见图15，假设分配给TRP1的频域资源为RBG0和RBG2，分配给TRP2的频域资源为RBG1和RBG3，若DCI中的bitmap所指示的被分配用于进行数据传输的频域资源为RBG1和RBG2，则针对TRP1，TRP1可以在RBG2上与终端设备通信，针对TRP2，TRP2可以在RBG1上与终端设备通信。情况1所述的频域资源分配方法可以理解为预先分配频域资源，即一旦终端设备确定BWP的带 宽，便可以确定M份频域资源，而后，再通过bitmap或RIV等具体的取值，确定在哪些频域资源上传输数据，这种频域资源分配方法的实现过程较为简单，复杂度较低。
情况2、预定带宽为系统带宽
当预定带宽为系统带宽时，频域资源分配的方法可以采用BWP中的方法，只需要将BWP的相应参数替换为系统带宽的相应参数即可，例如，在计算系统带宽中的频域资源分配单元的个数时，将BWP中的RB的个数替换为系统带宽中的RB的个数，将BWP中的起始RB在系统带宽中的编号替换为系统带宽的起始RB的编号。因此，情况2下的资源分配过程可参见情况1进行理解，不再赘述。
情况3、预定带宽为调度带宽
调度带宽是指为终端设备调度的用于进行数据传输的频域资源所组成的带宽。在情况3下，频域资源分配可以基于调度带宽内的所有频域资源，即频域资源分配是从调度带宽内的第一个频域资源分配单元开始，直到该调度带宽内的最后一个频域资源分配单元结束。
在频域资源分配类型不同时，调度带宽的确定也有所不同，以下通过情况3.1(频域资源分配类型为Type0)、情况3.2(频域资源分配类型为Type1)对不同频域资源分配类型下频域资源分配的过程作示例性说明。
情况3.1、Type0
情况3.1下，调度带宽为bitmap指示的用于进行数据传输的VRB所组成的带宽或bitmap指示的用于进行数据传输的VRB所映射到的PRB所组成的带宽，bitmap所指示的用于进行数据传输的VRB包括至少一个RBG。示例性的，参见图21，若bitmap包括6个比特，6个比特分别用于指示RBG0至RBG5是否被分配用于进行数据传输，若1个bit置1代表对应的RBG被分配用于进行数据传输、且6个比特的值为110101时，RBG0、RBG1、RBG3和RBG5被分配用于进行数据传输。此时，调度带宽为由RBG0、RBG1、RBG3和RBG5对应的RB，即RB3、RB4、RB5、RB8、RB9、RB12和RB13所组成的带宽。
当PRG size未被配置为wideband时，频域资源分配单元可以为RBG或PRG或y个连续的RB或信道测量的测量子带。与RBG类似的，频域资源分配单元的划分也是按照系统带宽进行划分的，调度带宽中的频域资源分配单元的个数以及各个频域资源分配单元大小的计算方法与BWP中的频域资源分配单元的个数以及各个频域资源分配单元大小的计算方法类似，只不过将Q取值为该场景下的频域资源分配单元大小，BWP中的RB的个数替换为调度带宽中的RB的个数，BWP中的起始RB在系统带宽中的编号替换为调度带宽中的起始RB在系统带宽中的编号即可。示例性的，基于图21所示的调度带宽，参见图22，若频域资源分配单元大小为2时，调度带宽中有4个频域资源分配单元。
当PRG size被配置为wideband时，x为
Figure PCTCN2020109385-appb-000055
W为终端设备的调度带宽中包含的RB的个数。此时，频域资源分配单元可以为x个连续的RB。也就是说，在RB为PRB的情况下，当PRG的大小为全带宽时，以
Figure PCTCN2020109385-appb-000056
个PRB为频域资源分配单元确定M份频域资源。
具体的，当PRG的大小为全带宽时，M份频域资源中的第m份频域资源包括调度带宽中第

个PRB至第
Figure PCTCN2020109385-appb-000058
个PRB，M份频域资源中的第M份频域资源包括调度带宽中的剩余的PRB，m为大于0小于M的整数。其中，

是指

是指
Figure PCTCN2020109385-appb-000061
该情况下，频域资源分配单元是按照调度带宽进行划分的，从调度带宽的起始RB开始，每x个连续的RB为一个频域资源分配单元。其中，由于W不一定是M的整数倍，因此，最后一个频域资源分配单元的大小可以是小于x的。示例性的，基于图21所示的调度带宽，若M＝2，则x＝4，参见图23，调度带宽中可以包括2个频域资源分配单元。其中，频域资源分配单元0的大小为4，频域资源分配单元1的大小为3。
在情况3.1下，频域资源分配方法可以为：终端设备确定M份频域资源中的第m份频域资源，第m份频域资源包括终端设备的调度带宽中包括的N个频域资源分配单元中的第Mi+m个频域资源分配单元。相应的，第一网络设备将终端设备的调度带宽中包括的N个频域资源分配单元中的第Mi+m个分配给M份频域资源中的第m份频域资源。其中，N为正整数，m为大于0小于等于M的整数，
Figure PCTCN2020109385-appb-000062
该种交替频域资源分配方法，可以使得多份频域资源尽量离散地分布在调度带宽上，从而获得更好的频域分集增益。
示例性的，基于图22所示的调度带宽，包括4个频域资源分配单元。若M＝2，4个频域资源分配单元中的频域资源分配单元0和频域资源分配单元2为第1份频域资源，频域资源分配单元1和频域资源分配单元3为第2份频域资源。
情况3.1又可以分为以下情况3.1.1和情况3.1.2。
情况3.1.1、PRG size未被配置为wideband。
情况3.1.1下，频域资源分配单元可以为PRG、RBG、y个连续的RB或信道测量的测量子带。具体的频域资源分配过程与情况1.1.1是类似的，区别仅在于此处是作用在调度带宽上，情况1.1.1是作用在BWP中的，具体可参照情况1.1.1进行理解，不再赘述。
情况3.1.2、PRG size被配置为wideband。
情况3.1.2下，频域资源分配单元为x个连续的RB、且频域资源分配单元的划分是按照调度带宽进行划分的。具体的频域资源分配过程与情况1.1.2是类似的，区别仅在于此处是作用在调度带宽上，情况1.1.2是作用在BWP中的，具体可参照情况1.1.2进行理解，不再赘述。
情况3.2、Type1
情况3.2又可以分为情况3.2.1和情况3.2.2。
情况3.2.1、调度带宽为RIV指示的连续的VRB所组成的带宽。
情况3.2.1下，VRB和PRB之间可以进行频域交织，也可以不进行频域交织。
示例性的，参见图24，RIV指示的频域资源为VRB5至VRB11，则调度带宽为由VRB5至VRB11所组成的带宽。
当PRG size未被配置为wideband时，频域资源分配单元可以为VRB bundles(VRB和PRB之间进行频域交织时)或y个连续的VRB或信道测量的测量子带(测量子带包括的RB为VRB)。与RBG类似的，频域资源分配单元的划分也是按照系统带宽进行划分的，调度带宽中的频域资源分配单元的个数以及各个频域资源分配单元大小的计算方法可以参见BWP中的频域资源分配单元的个数以及各个频域资源分配单元大小的计算方法，只不过将Q取值为该场景下的频域资源分配单元大小，BWP中的RB的个数替换为调度带宽中的VRB的个数，BWP中的起始RB在系统带宽中的编号替换为调度带宽中的起始VRB在系统带宽中的编号即可。示例性的，基于图24所示的调度带宽，参见图25，若频域资源分配单元大小为2时，调度带宽中有4个频域资源分配单元。

该情况下，频域资源分配单元是按照调度带宽进行划分的，从调度带宽的起始VRB开始，每x个连续的VRB为一个频域资源分配单元。其中，由于W不一定是M的整数倍，因此，最后一个频域资源分配单元的大小可以是小于x的。示例性的，基于图24所示的调度带宽，若M＝2，则x＝4，参见图26，调度带宽中可以包括2个频域资源分配单元。其中，频域资源分配单元0的大小为4，频域资源分配单元1的大小为3。
在情况3.2.1下，频域资源分配方法可以为：终端设备确定M份频域资源中的第m份频域资源，第m份频域资源包括终端设备的调度带宽中包括的N个频域资源分配单元中的第Mi+m个频域资源分配单元。相应的，第一网络设备将终端设备的调度带宽中包括的N个频域资源分配单元中的第Mi+m个分配给M份频域资源中的第m份频域资源。其中，N为正整数，m为大于0小于等于M的整数，

该种交替频域资源分配方法，可以使得多份频域资源尽量离散地分布在调度带宽上，从而获得更好的频域分集增益。
示例性的，基于图25所示的调度带宽，包括4个频域资源分配单元。若M＝2，4个频域资源分配单元中的频域资源分配单元0和频域资源分配单元2为第1份频域资源，频域资源分配单元1和频域资源分配单元3为第2份频域资源。
在PRG size未被配置为wideband时，频域资源分配单元可以为VRB bundles(VRB和PRB之间进行频域交织时)或y个连续的VRB或信道测量的测量子带(测量子带包括的RB为VRB)。具体的频域资源分配过程与情况1.2.1中的在VRB域上进行频域资源分配的过程是类似的，区别仅在于此处是作用在调度带宽上，情况1.2.1是作用在BWP中的，具体可参照情况1.2.1进行理解，不再赘述。
在PRG size被配置为wideband时，频域资源分配单元为x个连续的VRB、且频域资源分配单元的划分是按照调度带宽进行划分的。具体的频域资源分配过程与情况1.2.2中的在VRB域上进行频域资源分配的过程是类似的，区别仅在于此处是作用在调度带宽上，情况1.2.2是作用在BWP中的，具体可参照情况1.2.2进行理解，不再赘述。
情况3.2.2、调度带宽为RIV指示的连续的VRB映射到的PRB所组成的带宽。
情况3.2.2下，VRB和PRB之间可以进行频域交织，也可以不进行频域交织。在不进行频域交织时，频域资源分配单元可以为PRG或y个连续的PRB或信道测量的测量子带(测量子带包括的RB为PRB)。此时，频域资源分配单元的个数和各个频域资源分配单元大小、以及频域资源分配过程与情况1.2中的在PRB域上进行频域资源分配的过程是类似的，区别仅在于此处是作用在调度带宽上，情况1.2是作用在BWP中的，具体可参照情况1.2进行理解，具体的，当PRG size未被配置为wideband时，可参照情况1.2.1进行理解，当PRG size被配置为wideband时，可参照情况1.2.2进行理解，不再赘述。
该部分主要介绍VRB和PRB之间进行频域交织时频域资源分配的方法。在进行频域交织时，示例性的，参见图27，RIV指示的频域资源为VRB5至VRB11，VRB5至VRB11映射到的PRB分别为PRB4、PRB5、PRB6、PRB7、PRB9、PRB10和PRB11，则调度带宽为由PRB4、PRB5、PRB6、PRB7、PRB9、PRB10和PRB11所组成的带宽。
当PRG size未被配置为wideband时，频域资源分配单元可以为PRG或PRB bundles或y个连续的PRB或信道测量的测量子带(测量子带包括的RB为PRB)。该情况下，调度带宽中的频域资源分配单元的个数为
Figure PCTCN2020109385-appb-000071
VRB与PRB之间进行频域交织时，若第1个VRB bundles包含的VRB的个数小于bundle size，例如，bundle size＝2，第1个VRB bundles仅包含一个VRB时，包含第1个VRB bundles映射到的PRB bundles的频域资源分配单元包含的PRB的个数是小于频域资源分配单元的大小的。最后一个VRB bundles同理。示例性的，参见图28，bundle size＝2，第1个VRB bundles仅包含VRB5，VRB5映射到PRB9，若频域资源分配单元的大小为2，则频域资源分配单元2仅包含1个PRB(即PRB9)，而其他频域资源分配单元均包含2个PRB。若频域资源分配单元的大小为4，则频域资源分配单元1仅包含3个PRB，其他频域资源分配单元包含4个PRB。若第1个VRB bundles包含的VRB的个数和最后一个VRB bundles包含的VRB的个数均等于bundle size，则每个频域资源分配单元包含的PRB的个数均等于频域资源分配单元的大小。

该情况下，频域资源分配单元是按照调度带宽进行划分的，从调度带宽的起始PRB开始，每x个连续的PRB为一个频域资源分配单元。其中，由于W不一定是M的整数倍，因此，最后一个频域资源分配单元的大小可以是小于x的。示例性的，基于图28所示的调度带宽，若M＝2，则x＝4，参见图29，调度带宽中可以包括2个频域资源分配单元。其中，频域资源分配单元0的大小为4，频域资源分配单元1的大小为3。
在情况3.2.2下，频域资源分配方法可以为：终端设备确定M份频域资源中的第m份频域资源，第m份频域资源包括终端设备的调度带宽中包括的N个频域资源分配单元中的第Mi+m个频域资源分配单元。相应的，第一网络设备将终端设备的调度带宽中包括的N个频域资源分配单元中的第Mi+m个分配给M份频域资源中的第m份频域资源。其中，N为正整数，m为大于0小于等于M的整数，
Figure PCTCN2020109385-appb-000079
该种交替频域资源分配方法，可以使得多份频域资源尽量离散地分布在调度带宽上，从而获得更好的频域分集增益。
示例性的，基于图28所示的调度带宽，若频域资源分配单元的大小为2，则调度带宽包括4个频域资源分配单元。若M＝2，4个频域资源分配单元中的频域资源分配单元0和频域资源分配单元2为第1份频域资源，频域资源分配单元1和频域资源分配单元3为第2份频域资源。
在PRG size未被配置为wideband时，频域资源分配单元可以为PRG或PRB bundles 或y个连续的PRB或信道测量的测量子带(测量子带包括的RB为PRB)。具体的频域资源分配过程与情况1.2.1中的在PRB域上进行频域资源分配的过程是类似的，区别仅在于此处是作用在调度带宽上，情况1.2.1是作用在BWP中的，具体可参照情况1.2.1进行理解，不再赘述。
在PRG size被配置为wideband时，频域资源分配单元为x个连续的PRB、且频域资源分配单元的划分是按照调度带宽进行划分的。具体的频域资源分配过程与情况1.2.2是类似的，区别仅在于此处是作用在调度带宽上，情况1.2.2是作用在BWP中的，具体可参照情况1.2.2进行理解，不再赘述。
在情况3下，第一网络设备或终端设备所分配的M份频域资源为用于进行数据传输的频域资源。该情况下，各个网络设备(例如，上述M个网络设备)在M份频域资源上发送数据，相应的，终端设备在M份频域资源上接收数据。
上述实施例中，预定带宽为BWP或系统带宽时，上述情况1所述的资源分配方法虽然实现过程简单，但是可能会使得实际用于进行数据传输的频域资源恰好都属于同一份频域资源，例如，参见图15，若bitmap取值为1010，1个bit置1代表对应的RBG被分配用于进行数据传输，此时，RBG0和RBG2被分配用于进行数据传输，而RBG0和RBG2属于同一份频域资源，也就意味着，只能一个TRP与终端设备进行通信。预定带宽为调度带宽时，情况3所述的资源分配方法由于是在用于进行数据传输的频域资源上采用交替分配规则进行频域资源分配的，因此，每个TRP分配到的频域资源是大致相等的，因此，可以保证每个与终端设备通信的TRP都有资源可用。
本申请实施例提供的方法，可以避免同一个PRG内的PRB被分配给不同的TRP，也就是保证了同一个PRG内的PRB上的数据采用同一发送预编码矩阵进行预编码，从而与通信协议中的相关规定(即一个PRG中的PRB上的数据要采用相同的发送预编码矩阵进行预编码)保持一致。同时，针对同一个PRG内的PRB上的数据，终端设备可以采用同一个信道均衡矩阵解多流数据，从而保证终端设备的信号接收质量。
终端设备和第一网络设备在进行频域资源分配之前，需要先确定频域资源分配单元，频域资源分配单元可以为预设的或预定义的或协议规定的，也可以通过以下方式1或方式2确定。
方式1、频域资源分配单元为通过信令指示的。
其中，该信令可以为高层信令(例如，RRC信令、MAC CE信令等)或动态信令(例如，DCI)。
例如，该信令可以通过多个比特指示频域资源分配单元为RBG、PRG、交织资源单元或是信道测量的测量子带中的一种。
再例如，该信令可以通过1个或多个比特指示频域资源分配单元为VRB还是PRB。进一步的，如果频域资源分配单元的最小粒度为系统预设的，例如系统预设x＝2，或，系统预设频域资源分配单元的最小粒度为PRG(此时，x＝PRG size)的情况下，还可以通过1个或多个比特指示k的值，以用于计算y的值，其中，y＝k*x。
方式1使得终端设备可以基于指示灵活的切换频域资源分配单元。
方式2、频域资源分配单元的粒度与传输方案对应。
其中，传输方案可以为第一传输方案或第二传输方案。关于第一传输方案和第二传输 方法的描述可参见上文，在此不再赘述。在不同的传输方案下，频域资源分配单元可以不同，以下通过第一种情况和第二种情况分别进行描述。
第一种情况：
在第一传输方案下，频域资源分配单元为RBG。
在第二传输方案下，频域资源分配单元为PRG。
可选的，第一种情况下，频域资源分配类型可以为Type0，且预定带宽为BWP或系统带宽。
参见图30中的(a)所示的两份频域资源，假设第1份频域资源分配给了TRP1，第2份频域资源分配给了TRP2，若bitmap中包含4个比特，4个比特分别用于指示4个RBG是否被分配用于进行数据传输，若4个比特为0010，0代表未被分配用于进行数据传输，1代表被分配用于进行数据传输，此时，TRP1可用于进行数据传输的资源包括RB8至RB11，TRP2没有可用于进行数据传输的RB，由此可知，这种分配方式更加的灵活，更加适用于第一传输方案。
参见图30中的(b)所示的两份频域资源，假设第1份频域资源分配给了TRP1，第2份频域资源分配给了TRP2，若bitmap中包含4个比特，4个比特分别用于指示4个RBG是否被分配用于进行数据传输，若4个比特为0010，0代表未被分配用于进行数据传输，1代表被分配用于进行数据传输，此时，TRP1可用于进行数据传输的资源包括RB10和RB11，TRP2可用于进行数据传输的资源包括RB8和RB9，由此可知，这种分配方式更加的均匀，更加适用于第二传输方案。
第二种情况：
在第一传输方案下，连续的RB为连续的PRB。
在第二传输方案下，连续的RB为连续的VRB。
可选的，第二种情况下，频域资源分配类型可以为Type1、VRB和PRB之间进行频域交织、且预定带宽为BWP或系统带宽。
示例性的，参见图31中的(a)，当连续的RB为连续的PRB时，假设第1份频域资源分配给了TRP1，第2份频域资源分配给了TRP2，RIV所指示的可用于进行数据传输的VRB包括VRB6至VRB12，VRB6至VRB12映射到的PRB可参见图31中的(a)，此时，TRP1可用于进行数据传输的PRB包括PRB8，TRP2可用于进行数据传输的PRB包括PRB2、PRB3、PRB6、PRB7、PRB10和PRB11，由此可知，这种分配方式在交织后，M份频域资源可能不均衡，更加适用于第一传输方案。
示例性的，参见图31中的(b)，当连续的RB为连续的VRB时，假设第1份频域资源分配给了TRP1，第2份频域资源分配给了TRP2，RIV所指示的可用于进行数据传输的VRB包括VRB6至VRB12，VRB6至VRB12映射到的PRB可参见图31中的(b)，此时，TRP1可用于进行数据传输的PRB包括PRB2、PRB3、PRB6和PRB7，TRP2可用于进行数据传输的PRB包括PRB8、PRB10和PRB11，由此可知，这种分配方式更加的均衡，更加适用于第二传输方案。
第二种情况中，终端设备可以根据实际的传输方案选择频域资源分配单元，增加了终端设备的调度灵活性和对不同传输方案的支持。
需要说明的是，上述第一种情况和第二种情况仅仅是对传输方案与频域资源分配单元 的粒度之间的对应关系作了一个示例，传输方案与频域资源分配单元的粒度之间的对应关系不仅限于此。例如，在第一种情况下，也可以第一传输方案下，频域资源分配单元为PRG，第二传输方案下，频域资源分配单元为RBG。在第二种情况下，也可以第一传输方案下，连续的RB为连续的VRB，第二传输方案下，连续的RB为连续的PRB。另外，传输方案也可以与其他的频域资源分配单元的粒度(例如，交织资源单元或信道测量的测量子带等)对应，也可以不与任何频域资源分配单元的粒度对应，本申请对此不作限制。
另外，需要说明的是，根据上述描述可知，预定带宽为BWP或系统带宽时，频域资源分配可能不均衡，预定带宽为调度带宽时，频域资源分配是更加均衡的，因此，传输方案还可以与预定带宽对应，例如，第一传输方案对应BWP或系统带宽，第二传输方案对应调度带宽。
需要说明的是，本申请实施例中的RBG、PRG、交织资源单元和信道测量的测量子带的大小的描述是依据协议中的相关规定进行描述的，在实际实现时或未来协议中，RBG、PRG、交织资源单元和信道测量的测量子带的大小也可以比本申请描述的更大或更小，此时，对于本申请同样适用。
另外，本申请主要目的在于阐述频域资源如何分配，因此，对于时域资源并未过多描述，但是可以理解的是，各个网络设备和终端设备在发送数据时，不仅仅需要确定频域资源，还需要确定时域资源，对于时域资源确定的方法本申请不作限定。
