本申请要求在2022年04月28日提交中国专利局、申请号为202210471396.2、申请名称为“一种信息传输方法及装置”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，尤其涉及一种信息传输方法及装置。
背景技术
第五代移动通信系统(5th generation，5G)可以采用高频通信，即采用高频段信号传输数据。高频通信的一个主要问题是信号能量随传输距离急剧下降，导致信号传输距离短。为了克服这个问题，高频通信采用模拟波束技术，通过对天线阵列进行加权处理，将信号能量集中在一个较小的角度范围内，形成一个类似于光束一样的信号(称为模拟波束，简称波束)，从而提高传输距离。网络设备和终端设备之间采用波束进行传输。
在进行上下行数据传输时，网络设备和终端设备需要采用特定的波束来进行。具体采用哪个波束来进行传输是通过波束测量过程来确定的。在多站传输模式下，网络设备可以为终端设备配置两个资源集合，分别对应两个不同传输接收站点(transmission and reception point，TRP)。每个资源集合包含一个或多个资源，对于每个资源，网络设备通过一个波束发送该资源对应的信号，用于终端设备测量对应TRP的波束质量。终端设备将两个资源集合中的资源进行配对上报，即从每个资源集合各取一个质量较好的资源组成一对上报给网络设备。终端设备可以上报一个或多个这样的资源组(或称为波束组)，以及每个资源组内每个资源的参考信号接收功率(reference signal receiving power，RSRP)。
根据上述方法，网络设备可以根据终端设备上报的资源组，调度终端设备进行下行传输，但是不能调度终端设备进行上行传输，因此如何在测量过程中，使得网络设备确定如何调度终端设备进行上行传输，是一个亟待解决的问题。

具体实施方式
下面结合说明书附图对本申请实施例做详细描述。
本申请实施例提供的通信方法可以应用于第四代(4th generation，4G)通信系统，例如长期演进(long term evolution，LTE)，也可以应用于第五代(5th generation，5G)通信系统，例如5G新空口(new radio，NR)，或应用于未来的各种通信系统，例如，第六代(6th generation，6G)通信系统。
本申请实施例提供的方法和装置是基于同一或相似技术构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
以下，首先对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、本申请实施例中涉及的波束，是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型波束，形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术可以具体为数字波束成形技术、模拟波束成形技术和混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。
波束可以称为空域滤波器(spatial domain filter)，空间滤波器(spatial filter)，空域参数(spatial domain parameter)，空间参数(spatial parameter)，空域设置(spatial domain setting)，空间设置(spatial setting)，准共址(quasi-colocation，QCL)信息，QCL假设，或QCL指示等。波束可以通过传输配置指示状态(transmission configuration indicator state，TCI-state)参数来指示，或者通过空间关系(spatial relation)参数来指示。因此，本申请中，波束可以替换为空域滤波器，空间滤波器，空域参数，空间参数，空域设置，空间设置，QCL信息，QCL假设，QCL指示，TCI-state(包括上行TCI-state，下行TCI-state)，或空间关系等。上述术语之间也相互等效。波束也可以替换为其他表示波束的术语，本申请在此不作限定。
用于发送信号的波束可以称为发送波束(transmission beam，Tx beam)，空域发送滤波器(spatial domain transmission filter)，空间发送滤波器(spatial transmission filter)，空域发送参数(spatial domain transmission parameter)，空间发送参数(spatial transmission parameter)，空域发送设置(spatial domain transmission setting)，或者空间发送设置(spatial transmission setting)。下行发送波束可以通过TCI-state来指示。
用于接收信号的波束可以称为接收波束(reception beam，Rx beam)，空域接收滤波器(spatial domain reception filter)，空间接收滤波器(spatial reception filter)，空域接收参数(spatial domain reception parameter)或者空间接收参数(spatial reception parameter)，空域接收设置(spatial domain reception setting)，或者空间接收设置(spatial reception setting)。上行发送波束可以通过空间关系、上行TCI-state、探测参考信号(sounding reference signal，SRS)资源(表示使用该SRS的发送波束)中任一种来指示。因此，上行波束还可以替换为SRS资源。
发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
此外，波束可以是宽波束，或者窄波束，或者其他类型的波束。形成波束的技术可以 是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术、混合数字波束赋形技术或者混合模拟波束赋形技术等。
波束一般和资源对应，例如进行波束测量时，网络设备通过不同的资源来测量不同的波束，终端设备反馈测得的资源质量，网络设备就知道对应的波束的质量。当数据传输时，波束信息也是通过其对应的资源来进行指示的。例如，网络设备通过下行控制信息(downlink control information，DCI)中的传输配置指示(transmission configuration indicator，TCI)字段指示终端设备的物理下行共享信道(physical downlink shared channel，PDSCH)波束的信息。
可选的，将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或者多个天线端口，用于传输数据信道、控制信道和探测信号等。形成一个波束的一个或者多个天线端口也可以看作是一个天线端口集。
在本申请实施例中，若未做出特别说明，波束是指网络设备的发送波束。在波束测量中，网络设备的每一个波束对应一个资源，因此可以使用资源的索引来唯一标识该资源对应的波束。
2)、本申请实施例中涉及的上行波束，在当前协议中，上行传输的发送波束可以通过spatial relation来指示，其功能类似于TCI-state，用于告知终端设备采用什么发送波束来进行上行传输。
Spatial relation需要先通过无线资源控制(radio resource control，RRC)信令进行配置。其配置的信息，包括spatial relation的标识，小区标识，目标参考信号资源，路损测量参考信号，功控参数等。其中，目标参考信号资源用于指示对应的上行波束。如果上行传输采用spatial relation#1，该spatial relation#1中包括一个目标参考信号资源#2，则表示采用该上行传输的发送波束是该目标参考信号的发送/接收波束。例如，目标参考信号资源为上行资源探测参考信号(sounding reference signal，SRS)时，表示上行传输采用的发送波束是该SRS的发送波束(该SRS的发送波束是已知的)。又例如，目标参考信号资源为同步信号块(synchronization signal block，SSB)/信道状态信息-参考信号(channel state information-reference signal，CSI-RS)等下行资源，表示上行传输采用的发送波束是该SSB/CSI-RS的接收波束(该SSB/CSI-RS的接收波束是已知的)。
网络设备可以为终端设备配置多个spatial relation。然后通过媒体接入控制(media access control，MAC)控制元素(control element，CE)激活其中的一个用于对应的数据传输。上行传输包括物理上行链路控制信道(physical uplink control channel，PUCCH)、SRS、上行物理共享信道(physical uplink share channel，PUSCH)等，都需要对应的spatial relation。PUCCH的spatial relation是通过MAC CE信令指示的。SRS的spatial relation也是通过MAC-CE信令指示的。PUSCH传输时会关联特定的SRS，并采用该SRS的spatial relation进行传输。
3)、本申请实施例中涉及的下行波束，可以通过TCI-state进行指示。
网络设备可以生成不同的波束，指向不同的传输方向。在下行数据传输中，网络设备在采用一个特定的波束向终端设备发送数据时，需要告知终端设备其采用的发送波束信息，这样终端设备才能采用与该发送波束相对应的接收波束来接收网络设备发送的数据。在第三代伙伴计划(the 3rd generation partnership project，3GPP)R15/R16协议中，网络设备通过DCI中的传输配置编号(transmission configuration index，TCI)字段向终端设备指示其 采用的发送波束的相关信息。具体的，TCI字段大小为3bit，可以具体表示8个不同的字段值(codepoint)。TCI字段的每个值对应一个TCI-state的索引，该TCI-state索引可以唯一标识一个TCI-state。TCI-state包括若干参数，通过这些参数可以确定发送波束的相关信息。TCI-state是由网络设备配置给各个终端设备的，每个TCI-state包括一个自身的索引和两个QCL信息(QCL-Info)。每个QCL-Info包括一个小区(cell)字段和带宽部分(bandwidth part，BWP)标识(bwp-Id)，分别表示该TCI-state应用于哪个小区的哪个BWP，即不同cell或同一cell的不同BWP可以配置不同QCL-Info。QCL-Info还包括一个参考信号(reference signal，RS)，用于表示与哪个参考信号资源构成QCL关系。在R15/R16协议中，一般不会直接出现“波束”这个词汇，波束一般是通过其他术语进行代替的。例如，在数据传输和信道测量中，波束都是与参考信号资源进行对应的，一个波束对应一个参考信号资源。因此，此处说与哪个参考信号资源构成QCL关系，实质是指与哪个波束构成QCL关系。QCL关系是指两个参考信号资源(或两个天线端口，天线端口和参考信号资源也是一一对应的)在具有某些同一的空间参数。具体哪些空间参数是同一的取决于该QCL-Info的类型，即QCL-Info的另一个QCL类型(qcl-Type)字段。QCL类型可以有四种取值{typeA，typeB，typeC，typeD}。以typeD为例，typeD表示两个参考信号资源具有同一的空间接收参数信息，即两个波束具有同一的接收波束。TCI-state包括的两个QCL-Info中最多只能有一个是TypeD的。
4)、本申请实施例中涉及的公共波束，指的是网络设备为终端设备指示的一个波束，该波束可以同时用于多个信道和/或参考信号。在本申请实施例中将该波束称为公共波束，也可以为其他的名称，本申请不做具体限定，并且，公共波束可以包括上行公共波束、下行公共波束、上下行公共波束。上行公共波束可以用于多个上行信道和/或上行参考信号的传输，下行公共波束可以用于多个下行信道和/或下行参考信号的传输。上下行公共波束可以用于多个上行信道和/或上行参考信号，以及多个下行信道和/或下行参考信号的传输，即该上下行公共波束既可以用于上行传输，也可以用于下行传输。
需要注意的是，上述公共波束可以具体是TCI-state，或其他表述，本申请不做具体限定。另外，若无特殊说明，本申请实施例中公共波束可以泛指上行公共波束，下行公共波束和上下行公共波束中的任意一种。
(5)、本申请实施例中涉及的天线面板(panel)，可以是网络设备的天线面板，也可以是终端设备的天线面板。一个天线面板上一般有一个或多个天线，这些天线组成天线阵列，进行波束赋形，从而形成模拟波束。该天线阵列可以生成指向不同方向的波束，但同一时间只能生成一个波束。也就是说每个天线面板上都可以形成多个波束，可以通过波束测量来确定该天线面板采用哪个波束是最好的。终端设备可以配备多个天线面板，这些天线面板可以分布在不同的位置，朝向不同的方向，这可以保证无论终端设备朝向哪个方向，都至少有一个天线面板是朝向网络设备的，可以与网络设备进行数据传输。例如图1所示，该终端设备配备了两个天线面板，每个天线面板朝向不同的方向，每个天线面板可以生成多个不同方向的波束，从而构成较为全面的波束覆盖，图1中以终端设备通过天线面板1生成波束1，通过天线面板2生成波束2为例进行描述。终端设备可以同时开启所有天线面板进行传输。或者，为了降低终端设备功耗，终端设备也可以一次采用单个天线面板进行传输，其他未使用的天线面板可以进行关闭。终端设备的天线面板处于打开还是关闭状态一般需要通知给网络设备。
在本申请实施例中，天线面板可以简称为面板，天线面板也可以用天线面板索引(panel index)等来表示。除此之外，也可以通过其他方式来隐含表示天线面板，例如天线面板也可以通过天线端口(如CSI-RS端口，SRS端口，解调参考信号(demodulation reference signal，DMRS)端口，相位跟踪参考信号(phase tracking reference signal,PTRS)端口，CRS端口，时频跟踪参考信号(tracking reference signal,TRS)端口，SSB端口等)或天线端口组来表征，也可以通过资源(如CSI-RS资源，SRS资源，DMRS资源，PTRS资源，小区参考信号(cell reference signal,CRS)资源，TRS资源，SSB资源等)或资源组来表征，也可以通过某个信道表征(如PUCCH，PUSCH，物理随机接入信道(physical random access channel，PRACH)，PDSCH，PDCCH，物理广播信道(physical broadcast channel,PBCH)等)，也可以通过波束，QCL，TCI-state，spatial relation或配置在QCL，TCI-state，spatial relation中的某个索引来表征。也可以通过波束组，QCL组，TCI-state组，spatial relation组等来表征。也就是说，本申请中所述的天线面板/panel标识可以替换为上述内容的标识。
(6)、本申请实施例中涉及的多个，是指两个或两个以上。“和/或”，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。字符“/”一般表示前后关联对象是一种“或”的关系。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
(7)、本申请实施例的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“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它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。
本申请实施例中涉及的网络设备，可以为无线网络中的设备。例如，网络设备可以是部署在无线接入网中为终端设备提供无线通信功能的设备。例如，网络设备可以为将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点，又可以称为接入网设备。
网络设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G移动通信系统中的网络设备。例如，NR系统中的下一代基站(next generation NodeB，gNB)，传输接收点(transmission reception point，TRP)，TP；或者，5G移动通信系统中的基站的一个或一组(包括多个天线面板)天线面板；或者，网络设备还可以为构成gNB或传输点的网络节点。例如，BBU，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可 以包括有源天线单元(active antenna unit，AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能。例如，CU负责处理非实时协议和服务，实现无线资源控制RRC，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、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。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。因此在该架构下，高层信令(如RRC层信令)也可以认为是由DU发送的，或者，由DU和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节点中一个或多个的设备。此外，可以将CU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，本申请对此不做限定。
本申请实施例中涉及的终端设备,可以是能够接收网络设备调度和指示信息的无线终端设备。终端设备可以是指向用户提供语音和/或数据连通性的设备，或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。
终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备是包括无线通信功能(向用户提供语音/数据连通性)的设备。例如，具有无线连接功能的手持式设备、或车载设备等。目前，一些终端设备的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、车联网中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端等。例如，车联网中的无线终端可以为车载设备、整车设备、车载模块、车辆等。工业控制中的无线终端可以为摄像头、机器人等。智慧家庭中的无线终端可以为电视、空调、扫地机、音箱、机顶盒等。
下面对采用波束进行通信的技术进行简单介绍。
在5G通信系统中，网络设备与终端设备之间可以采用波束进行数据传输，网络设备可以由自身决定使用什么波束，而终端设备通过网络设备指示使用什么波束，例如网络设备向终端设备发送一个下行控制信息，该下行控制信息中包含传输配置编号TCI字段，该TCI字段可以用于指示一个TCI-state，该TCI-state用于上行传输或下行传输，并且该TCI-state中包括一个目标参考信号资源。针对采用该TCI-state进行下行传输时，终端设备采用该目标参考信号资源对应的接收波束进行接收，由于该目标参考信号资源对应的接收波束是终端设备已经确定的，因此，网络设备可以为终端设备指示正确的接收波束。针对采用该TCI-state进行上行传输时，终端设备采用该目标参考信号对应的发送波束进行发送，或者采用该目标参考信号对应的接收波束进行发送。
对于配备了多个天线面板的终端设备，终端设备可以支持多站传输模式。在多站传输模式下，终端设备可以使用两个天线面板与两个不同传输接收站点(transmission and reception point，TRP)同时传输。例如，如图2所示，示出了本申请实施例提供的一种多站传输模式示意图，终端设备可以与多个TRP进行数据传输，图中以2个TRP为例，分别为TRP1和TRP2。多个TRP可能是属于同一小区的，也可能属于不同小区的。属于同 一小区时，多个TRP的测量参数是统一配置的。属于不同小区时，不同TRP的测量参数是单独配置的。
终端设备与两个TRP同时传输时，网络设备可以为终端设备配置两个资源集合，分别对应两个不同TRP。每个资源集合包含一个或多个资源，对于每个资源，网络设备通过一个波束发送该资源对应的信号，用于测量对应TRP波束质量。终端设备可以将两个资源集合中的资源进行配对上报，即从每个资源集合各取一个质量较好的资源组成一对上报给网络设备。终端设备可以上报一个或多个这样的资源组(或称为波束组)，以及每个资源组内每个资源的RSRP。
进一步的，终端设备需要保证每个资源组中的两个资源是能被其同时接收的，这样网络设备就可以根据终端设备上报资源组信息，确定两个TRP分别发送什么波束给终端设备是比较好的，从而实现多TRP同时传输。如图3所示，每个资源组中的两个资源能被终端设备同时接收有两种情况：情况一，如图3中的(a)所示，该资源组中的两个资源是被终端设备的同一天线面板上的同一接收波束接收的，图中以终端设备通过天线面板1接收资源1和资源2为例描述；情况二，如图3中的(b)所示，该资源组中的两个资源是被终端设备的两个天线面板上的接收波束接收的，即每个天线面板可以生成一个波束，两个资源的接收波束分别位于两个天线面板上，图中以终端设备通过天线面板1接收资源1和通过天线面板2接收资源2为例描述。
本申请提供一种方法，终端设备不仅向网络设备上报能被其同时接收的资源组，即两个TRP分别采用资源组中的资源对应的波束可以同时传输信号给终端设备，终端设备还可以向使网络设备上报资源组中每个资源对应的面板信息，使得网络设备确定资源组中的资源对应的接收波束是同一个面板上的同一个波束，还是不同面板上的波束，从而可以使得网络设备能够进行多面板上行传输调度。

下面的流程中，主要以终端设备最多与2个TRP同时传输为例进行描述，即网络设备最多为终端设备配置两个资源集合，终端设备上报的资源组中最多包括两个资源。当网络设备配置三个或三个以上资源集合，终端设备上报的资源组中包括三个或三个以上资源时，可以按照本申请提供的方法进行适应性调整。
如图4所示，为本申请实施例提供的一种信息传输方法流程示意图，该方法包括：
S401：终端设备向网络设备发送能力信息。
该能力信息可以指示以下至少一项信息：
终端设备是否支持在进行资源组(波束组)上报时，上报资源组对应的面板信息；
终端设备支持上报面板信息的资源组数量Q，Q为大于0的整数；
终端设备是否支持多波束或多面板同时传输；
终端设备的面板能力信息，面板能力信息可以用于指示终端设备的面板支持的最大发送端口数等信息。
其中，发送端口可以是指SRS端口等。最大发送端口数可以为大于或等于0的数，也可以为大于0的数，一个面板的最大发送端口数为0，表示该面板只用于下行传输，不用于上行传输。
假设终端设备包括X个面板，X为大于0的整数，每个面板对应一个最大发送端口数，不同面板对应的最大发送端口数可能相同，也可能不同。那么终端设备的面板能力信息包括的具体内容可能存在以下几种实现方式。
第一种实现方式中，该面板能力信息包括L1个第一参数，L1为大于0的整数。每个第一参数用于指示一个最大发送端口数，不同第一参数指示的最大发送端口数不同。每个第一参数还可以对应一个索引，不同第一参数对应的索引不同。其中，终端设备在上报每个第一参数时，可以同时上报每个第一参数的索引，也可以不上报每个第一参数的索引，如果不上报每个第一参数的索引，每个第一参数的索引可以为预设的，例如终端设备上报的L1个第一参数按照预设顺序排列，每个第一参数的索引与其顺序对应。举例来说，排在第一个的第一参数的索引为0，排在一个的第一参数的索引为1等，其他情况以此类推。
如果终端设备上报的最大发送端口数为大于或等于0的数，X个面板对应的X个最大发送端口数存在Y1种不同的取值，Y1为大于或等于0的整数，那么L1的取值可以小于或等于Y1。
如果终端设备上报的最大发送端口数为大于0的数，X个最大发送端口数中包括取值为0的最大发送端口数，那么L1的取值可以小于或等于Y1-1；若X个最大发送端口数中不包括取值为0的最大发送端口数，那么L1的取值可以小于或等于Y1。
举例来说，假设终端设备有三个面板，分别为第一面板、第二面板以及第三面板，这三个面板对应的最大发送端口数分别为1、1、2；那么Y1＝2，L1＝2。终端设备向网络设备上报2个第一参数，这2个第一参数分别为最大发送端口数可以如表1所示。
表1
假设终端设备有三个面板，分别为第一面板、第二面板以及第三面板，这三个面板对应的最大发送端口数分别为0、1、2；那么Y1＝3。如果终端设备上报的最大发送端口数为大于或等于0的数，那么终端设备上报3个第一参数，这3个第一参数分别为最大发送端口数可以如表2所示。
表2
如果终端设备上报的最大发送端口数为大于0的数，那么终端设备上报2个第一参数，这2个第一参数分别为最大发送端口数可以如表3所示。
表3
第二种实现方式中，该面板能力信息包括L2个第二参数，L2为大于0的整数。每个第二参数用于指示一个或多个最大发送端口数。每个第二参数还可以对应一个索引，不同第二参数对应的索引不同。其中，终端设备在上报每个第二参数时，可以同时上报每个第二参数的索引，也可以不上报每个第二参数的索引。如果不上报每个第二参数的索引，每个第二参数的索引可以为预设的，例如终端设备上报的L2个第二参数按照预设顺序排列，每个第二参数的索引与其顺序对应。举例来说，排在第一个的第二参数的索引为0，排在一个的第二参数的索引为1等，其他情况以此类推。
如果终端设备上报的最大发送端口数为大于或等于0的数，X个面板对应的X个最大发送端口数存在Y1种不同的取值，且Y1种取值中存在Y3种取值的最大发送端口数对应多个面板，Y3为大于或等于0的整数，那么L2的取值可以小于或等于Y1+Y3+Y1×(Y1-1)。
如果终端设备上报的最大发送端口数为大于0的数，X个面板对应的X个最大发送端口数中存在Y2种不同的大于0的取值，且Y2种取值中存在Y4种取值的最大发送端口数对应多个面板，Y4为大于或等于0的整数，那么L2的取值可以小于或等于Y2+Y4+Y2×(Y2-1)。
其中，如果一个第二参数用于指示一个最大发送端口数，该第二参数指示的最大发送端口数对应终端设备的一个面板；如果一个第二参数用于指示多个最大发送端口数，那么这多个最大发送端口数中的每个最大发送端口数对应终端设备的一个面板，即这多个最大发送端口数分别表示终端设备的多个面板的最大发送端口数。
举例来说，假设终端设备有三个面板，分别为第一面板、第二面板以及第三面板，这三个面板对应的最大发送端口数分别为1、1、2；那么Y1＝2，Y3＝1。
那么终端设备需要上报5＝2+1+2×(2-1)个第二参数，这5个第二参数指示的最大发送端口数可以如表4所示。
表4

其中，{1}表示该第二参数对应单个面板，该面板的最大发送端口数为1。{2}与{1}同理。{1，1}表示该第二参数对应两个面板，该两个面板的最大发送端口数分别为1和1。{1，2}、{1，1}与{2，1}同理。{1，2}和{2，1}的区别在于，{1，2}表示该第二参数对应的两个面板中的第一个和第二个面板对应的最大发送端口数分别为1和2，{2，1}表示该第二参数对应的两个面板中的第一个和第二个面板对应的最大发送端口数分别为2和1。
假设终端设备有三个面板，分别为第一面板、第二面板以及第三面板，这三个面板对应的最大发送端口数分别为0，1，2。如果终端设备上报的最大发送端口数为大于或等于0的数，那么Y1＝3，Y3＝0，终端设备需要上报9＝3+0+3×(3-1)个第二参数，这9个第二参数指示的最大发送端口数可以如表5所示。
表5
如果终端设备上报的最大发送端口数为大于0的数，那么Y2＝2，Y4＝0，终端设备需要上报4＝2+0+2×(2-1)个第二参数，这4个第二参数指示的最大发送端口数可以如表6所示。
表6
第三种实现方式中，该面板能力信息包括L2个第二参数，每个第二参数用于指示一个或多个最大发送端口数，以及一个或多个最大发送端口数对应的面板数。每个第二参数还可以对应一个索引，不同第二参数对应的索引不同。其中，L2的取值可以参考前面的描述，在此不再赘述。
举例来说，假设终端设备有三个面板，分别为第一面板、第二面板以及第三面板，这三个面板对应的最大发送端口数分别为1、1、2；那么Y1＝2，Y3＝1。
那么终端设备需要上报5＝2+1+2×(2-1)个第二参数，这5个第二参数指示的最大发送端口数可以如表7所示。
表7
其中，每个第二参数中的最后一个参数表示该第二参数对应的面板数，前面的一个或两个参数表示一个或两个面板对应的最大发送端口数。例如，第二参数为{2，1}，该第二参数中最后一个数字1，表示该第二参数对应1个面板，该第二参数中第一个数字2，表示该面板的最大发送端口数为2。第二参数为{1，2，2}，该第二参数中最后一个数字2，表示该第二参数对应2个面板，该第二参数中第一个数字2和第二个数字1，分别表示该两个面板的最大发送端口数分别为1和2。
假设终端设备有三个面板，分别为第一面板、第二面板以及第三面板，这三个面板对应的最大发送端口数分别为0，1，2。如果终端设备上报的最大发送端口数为大于或等于0的数，那么Y1＝3，Y3＝0，终端设备需要上报9＝3+0+3×(3-1)个第二参数，这9个第二参数指示的最大发送端口数可以如表8所示。
表8
如果终端设备上报的最大发送端口数为大于0的数，那么Y2＝2，Y4＝0，终端设备需要上报4＝2+0+2×(2-1)个第二参数，这4个第二参数指示的最大发送端口数可以如表9所示。
表9

以上只是示例，面板能力信息中包括的参数还可以存在其他可能的实现方式，本申请对此并不限定。
S402：网络设备向终端设备发送配置信息，该配置信息用于配置X个资源集合，X为大于1的整数。
其中，X个资源集合中的每个资源集合包括至少M个参考信号资源，每个参考信号资源可以对应一个波束，一个资源集合中，不同参考信号资源对应的波束可以相同，也可以不同，本申请对此并不限定。
网络设备具体如何发送配置信息，可能存在多种实现方式，例如网络设备可以通过高层信令向终端设备发送配置信息，该配置信息用于指示X个资源集合，具体的，网络设备可以在高层信令的资源配置(resource config)或资源设置(resource setting)字段中配置X个资源集合。对于X个资源集合中的每个参考信号资源，该配置信息可以指示每个参考信号资源的起始位置以及索引等信息。
该配置信息还可以用于配置终端设备波束上报的相关信息，例如可以指示以下一项或多项信息：
配置终端设备进行跨资源集合的资源组上报；可选地，网络设备配置或者协议规定，终端设备上报资源组中对应的参考信号资源对应的终端设备接收波束或面板是否可以用于上行同时传输或上行多波束同传或上行多面板同传；可选地，网络设备配置或者协议规定，终端设备上报的资源组必须能够被终端设备同时接收；
配置要上报的资源组的数量M的取值，M为大于0的整数，例如M的取值可以是{1，2，3，4}中的任意一种；
配置要上报面板信息的资源组的数量N的取值，表示需要终端设备上报M个资源组中的N个资源组对应的面板信息，N为小于或等于M，且大于0的整数。
其中，N也可以不需要配置，例如协议规定N等于M；或者预先约定N等于Q和M之间的最小值。
可选的，如果在S401中，终端设备上报的面板能力信息包括L1个第一参数，那么网络设备还可以根据这L1个第一参数确定L2个第二参数，每个第二参数用于指示一个或多个最大发送端口数，或者每个第二参数用于指示一个或多个最大发送端口数以及该一个或多个最大发送端口数对应的面板数。网络设备可以通过配置信息向终端设备发送L2个第二参数，也可以单独向终端设备发送L2个第二参数。其中，网络设备在发送L2个第二参数时，可以同时发送每个第二参数的索引，也可以不发送每个第二参数的索引。如果不发送每个第二参数的索引，每个第二参数的索引可以为预设的，例如网络设备发送的L2个第二参数按照预设顺序排列，每个第二参数的索引与其顺序对应。举例来说，排在第一个的第二参数的索引为0，排在一个的第二参数的索引为1等，其他情况以此类推。
进一步的，以一个资源组包括2个参考信号资源为例，网络设备确定的L2的取值可以小于或等于L1+L1×L1。
举例来说，假设每个第二参数用于指示一个或多个最大发送端口数，终端设备上报两个第一参数，分别为{1}，{2}，那么网络设备根据这两个第一参数确定的第二参数的数量 L2＝2+2×10＝6，这6个第二参数分别为{1}，{2}，{1，1}，{2，2}，{1，2}，{2，1}。上述第二参数的含义可以参考前面关于第二参数的描述，在此不再赘述。此时网络设备发送的L2个第二参数可以如表10所示。
表10
进一步的，以一个资源组包括2个参考信号资源为例，网络设备确定的L2的取值可以小于或等于L1+L1×L1。
再举例来说，假设每个第二参数用于指示一个或多个最大发送端口数以及所述一个或多个最大发送端口数对应的面板数，终端设备上报两个第一参数，分别为{1}，{2}，那么网络设备根据这两个第一参数确定的第二参数的数量L2＝2+2×10＝6，这6个第二参数分别为{1，1}，{2，1}，{1，1，2}，{2，2，2}，{1，2，2}，{2，1，2}。上述第二参数的含义可以参考前面关于第二参数的描述，在此不再赘述。网络设备发送的L2个第二参数可以如表11所示。
表11
S403：网络设备向终端设备发送X个资源集合中的参考信号资源。
具体的，网络设备可以通过X个资源集合中的每个参考信号资源分别向终端设备发送参考信号，每个参考信号资源中的参考信号采用该参考信号资源对应的波束发送。
S404：终端设备对X个资源集合中的参考信号资源进行测量，确定M个资源组。
终端设备可以对X个资源集合中每个参考信号资源中的参考信号进行测量，获得每个参考信号资源对应的测量信息，测量信息可以为RSRP等信息。
终端设备可以根据对X个资源集合中的每个参考信号资源测量获得的测量信息确定M个资源组。终端设备确定的每个资源组中的X个参考信号资源为从X个资源集合中分别选择的一个参考信号资源构成的，共确定M个资源组。即M个资源组中的每个资源组中包括X个参考信号资源，每个资源组中的X个参考信号资源属于X个资源集合中的不同资源集合，每个参考信号资源只能属于一个资源组。
终端设备具体如何从X个资源集合中确定M个资源组，本申请对此并不限定。举例来说，一种可能的实现方式中，假设测量信息为RSRP或者信号干扰噪声比(signal to  interference plus noise ratio，SINR)，终端设备可以从X个资源集合中的每个资源集合中选择一个参考信号资源，共选择了X个参考信号资源，每个资源集合中的参考信号资源被选择至一个资源组之后，不能被选择至其他资源组。终端设备从每个资源集合中选择的参考信号资源可以为该资源集合中RSRP或者SINR最大的参考信号资源，终端设备可以将这X个参考信号资源作为一个资源组；然后，终端设备再从每个资源集合中选择一个参考信号资源，共选择了X个参考信号资源，这X个参考信号资源又可以作为一组，以此类推，终端设备可以确定M个资源组。
进一步的，终端设备还可以确定M个资源组中需要上报面板信息的N个资源组。具体哪N个资源组是需要上报面板信息的资源组，本申请对此并不限定。举例来说，可以将M个资源组中平均RSRP最大的N个资源组，作为需要上报面板信息的资源组。或者也可以将M个资源组中平均RSRP最小的N个资源组，作为需要上报面板信息的资源组。
S405：终端设备向网络设备发送第一指示信息以及第二指示信息；相应的，网络设备接收来自终端设备的第一指示信息和第二指示信息。
其中，终端设备可以通过一条消息发送第一指示信息和第二指示信息，也可以通过不同的消息发送第一指示信息和第二指示信息。
其中，第一指示信息用于指示M个资源组。例如，第一指示信息包括M个资源组中每个资源的索引。第一指示信息还可以指示M个资源组中每个参考信号资源的测量信息，例如指示每个参考信号资源的RSRP或SINR等信息。
第二指示信息可以用于指示M个资源组中N个资源组分别对应的面板信息。具体的，第二指示信息包括N个面板信息，每个面板信息用于指示与该面板信息对应的资源组的以下至少一项信息：信息一，资源组中每个参考信号资源对应的面板的最大发送端口数；信息二，资源组中的X个参考信号资源对应的面板是否相同；信息三，资源组中的X个参考信号资源对应的面板数。
举例来说，以资源组中包括两个参考信号资源为例，信息一可以包括两个最大发送端口数或者最大发送端口数的索引，面板信息中的信息二和信息三可以位于信息一的前面，例如可以如表12所示。
表12
如果信息二指示资源组中的两个参考信号资源对应的面板相同，那么可以认为这两个参考信号资源对应的面板的最大发送端口数相同，而且可以确定这两个参考信号资源对应1个面板，此时面板信息中可以不包括信息三，而且信息二可以只包括一个最大发送端口数或者最大发送端口数的索引。
再举例来说，以资源组中包括两个参考信号资源为例，信息一可以包括两个最大发送端口数或者最大发送端口数的索引，面板信息中的信息一可以位于信息二和信息三的前面，例如可以如表13所示。
表13

如果信息一包括的两个最大发送端口数或者最大发送端口数的索引不相同，那么可以认为这两个参考信号资源对应的面板不同，而且可以确定这两个参考信号资源对应2个面板，此时面板信息中可以不包括信息二和信息三。
可选的，面板信息还可以用于指示面板信息在M个资源组中对应的资源组，例如面板信息还用于指示面板信息对应的资源组的资源组标识。例如，面板信息包括资源组标识字段，该字段用于指示面板信息对应的资源组，该字段中可以包括面板信息对应的资源组的标识。该字段的长度可根据M和N的大小关系来确定。其中，当N<M时，该字段长度可以为log2M向上取整；当N＝M时，该字段长度可以为0，这时上报的N＝M个面板信息与M个资源组一一对应，可以不具体指示每个面板信息对应的资源组。
如果面板信息不指示面板信息在M个资源组中对应的资源组，那么可以预先约定N个资源组在M个资源组中的位置。举例来说，存在对应面板信息的N个资源组为M个资源组中的预设N个资源组。例如，终端设备上报的M个资源组按照编号的顺序进行排列，可以预先约定将存在对应面板信息的N个资源组排在前面，即排列在前面的N个资源组存在对应的面板信息。
通过上面的方法，终端设备可以指示这N个资源组是属于M个资源组中的哪N个资源组。
可选的，如果面板信息对应的资源组中的两个参考信号资源对应不同的面板，面板信息还用于指示与面板信息对应的资源组中的两个参考信号资源对应的两个面板是否能够用于上行多波束同传或上行多面板同传，或者，用于指示对应的资源组中的两个参考信号资源对应的接收波束或面板是否可以用于上行同时传输。如果面板信息对应的资源组中的所有资源对应相同的面板，则可以不包括该信息。
一种实现方式中，所述面板信息还用于指示与所述面板信息对应的资源组中的两个参考信号资源对应的面板或终端接收波束是否能够用于上行多面板同传或上行同时传输或上行多波束同传，或者，用于指示对应的资源组中的两个参考信号资源对应的接收波束或面板是否可以用于上行同时传输。具体的，面板信息可以为1比特字段，当该字段为0时，指示与所述面板信息对应的资源组中的两个参考信号资源对应的面板或终端接收波束不能够用于上行多面板同传或上行同时传输或上行多波束同传，当该字段为1时，指示与所述面板信息对应的资源组中的两个参考信号资源对应的面板或终端接收波束能够用于上行多面板同传或上行同时传输或上行多波束同传。可选的，如果面板信息对应的资源组中的所有资源对应相同的面板，则可以不包括该信息。
本申请实施例中，面板信息可以存在多种实现方式，下面以资源组中包括两个参考信号资源(分别为第一参考信号资源和第二参考信号资源)为例，分别进行描述。
第一种可能的实现方式，以终端设备与网络设备之间约定L1个第一参数为例，面板信息可以包括以下至少一项信息：
第一信息，第一信息用于指示L1个第一参数中一个第一参数，第一信息对应的第一参数指示的最大发送端口数为第一参考信号资源对应的面板的最大发送端口数；
第二信息，第二信息用于指示L1个第一参数中一个第一参数，第二信息对应的第一参数指示的最大发送端口数为第二参考信号资源对应的面板的最大发送端口数；其中，第一信息和第二信息可以指示面板信息对应的资源组中每个参考信号资源对应的面板的最 大发送端口数；
第三信息，第三信息用于指示与面板信息对应的资源组中的X个参考信号资源对应的面板是否相同；
第四信息，第四信息用于指示资源组中的X个参考信号资源对应的面板数。
其中，第一信息可以为L1个第一参数中一个第一参数，也可以为L1个第一参数中一个第一参数的索引，也可以为其他指示第一参数的信息；第二信息可以为L1个第一参数中一个第一参数，也可以为L1个第一参数中一个第一参数的索引，也可以为其他指示第一参数的信息。如果面板信息中不包括第四信息，可以通过间接方式指示资源组中的X个参考信号资源对应的面板数，例如，当面板信息对应的资源组中的X个参考信号资源对应同一个面板时，表示资源组中的X个参考信号资源对应的面板数为1，此时可以不包括第四信息；例如，当资源组中包括2个参考信号资源时，如果面板信息对应的资源组中的2个参考信号资源对应不同面板，表示资源组中的2个参考信号资源对应的面板数为2，此时也可以不包括第四信息。
举例来说，假设终端设备上报2个第一参数，分别为{1}和{2}，对应的索引分别为0和1。如果一个资源组中包括两个参考信号资源，分别为第一参考信号资源和第二参考信号资源，第一参考信号资源对应的面板的最大发送端口数为1，第二参考信号资源对应的面板的最大发送端口数为2，那么该资源组对应的面板信息可以如表14所示。
表14
其中，第一信息为0，代表第一信息指示的第一参数为{1}，即指示第一参考信号资源对应的面板的最大发送端口数；第二信息为1，代表第二信息指示的第一参数为{2}，即指示第二参考信号资源对应的面板的最大发送端口数。第三信息为0时，表示第一参考信号资源和第二参考信号资源对应的面板不同，相应的，如果第三信息为1，表示第一参考信号资源和第二参考信号资源对应的面板相同。第四信息为1时，表示第一参考信号资源和第二参考信号资源对应的面板数为2，相应的，如果第四信息为0，表示第一参考信号资源和第二参考信号资源对应的面板数为1。
第二种可能的实现方式，以终端设备与网络设备之间约定L2个第二参数，每个所述第二参数用于指示一个或多个最大发送端口数为例，该实现方式中，面板信息可以用于指示L2个第二参数中一个第二参数，从而实现指示信息一、信息二以及信息三中的至少一个。例如，面板信息可以为L2个第二参数中一个第二参数，或者面板信息可以为L2个第二参数中一个第二参数的索引。
该实现方式中，面板信息用于指示L2个第二参数中一个第二参数时，相当于面板信息用于指示一个或多个最大发送端口数。
其中，面板信息指示一个最大发送端口数时，面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数和第二参考信号资源对应的面板的最大发送端口数相等，且等于面板信息指示的第二参数指示的最大发送端口数，面板信息对应的资源组中的第一参考信号资源和第二参考信号资源对应同一个面板；
面板信息指示多个最大发送端口数时，第一参考信号资源对应的面板的最大发送端口数以及第二参考信号资源对应的面板的最大发送端口数为多个最大发送端口数中的两个最大发送端口数，面板信息对应的资源组中的第一参考信号资源和第二参考信号资源对应不同的面板。
举例来说，假设存在6个第二参数，第二参数与索引的对应关系可以如表15所示。
表15
结合表15，如果面板信息为001，面板信息指示的第二参数为{2}，该第二参数指示的最大发送端口数为2。如果一个资源组中包括两个参考信号资源，分别为第一参考信号资源和第二参考信号资源，那么该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，且第一参考信号资源和第二参考信号资源对应同一个面板，即第一参考信号资源和第二参考信号资源对应的面板数为1。如果面板信息为011，面板信息指示的第二参数为{2，2}，该第二参数指示的两个最大发送端口数分别为2和2，表示该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，但是第一参考信号资源和第二参考信号资源对应不同的面板，即第一参考信号资源和第二参考信号资源对应的面板数为2。其他情况可以以此类推，不再赘述。
上面的例子以面板信息为第二参数的索引为例，面板信息也可以为第二参数。例如，结合表15，如果面板信息为{2}，该面板信息指示的最大发送端口数为2。那么该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，且第一参考信号资源和第二参考信号资源对应同一个面板，即第一参考信号资源和第二参考信号资源对应的面板数为1。如果面板信息为{2，2}，该面板信息指示的两个最大发送端口数分别为2和2，表示该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，但是第一参考信号资源和第二参考信号资源对应不同的面板，即第一参考信号资源和第二参考信号资源对应的面板数为2。其他情况可以以此类推，不再赘述。
进一步的，如果终端设备上报的最大发送端口数为大于0的数，那么面板信息还用于指示与面板信息对应的资源组中的两个参考信号资源对应的一个或两个面板是否能够用于上行传输或上行多波束同传或上行多面板同传。例如，结合表15，面板信息为000～101时，用于指示一个第二参数，面板信息为110～111中的一个时，面板信息的对应资源组中的两个参考信号资源中存在至少一个参考信号资源对应的最大发送端口数可能为0，不能用于上行同传。此时，若面板信息为110～111中的一个时，表示面板信息对应的资源组中的两个参考信号资源对应的一个或两个面板不能用于上行传输或上行多波束同传或上行 多面板同传。
进一步的，如果每个第二参数用于指示一个或多个最大发送端口数以及一个或多个最大发送端口数对应的面板数，那么该实现方式中，面板信息用于指示L2个第二参数中一个第二参数时，相当于面板信息用于指示一个或多个最大发送端口数以及一个或多个最大发送端口数对应的面板数。此时面板信息对应的资源组中X个参考信号资源对应面板数，等于面板信息指示的面板数。
举例来说，假设存在6个第二参数，第二参数与索引的对应关系可以如表16所示。
表16
结合表16，如果面板信息为001，面板信息指示的第二参数为{2，1}，该第二参数指示的最大发送端口数为2，指示的面板数为1。如果一个资源组中包括两个参考信号资源，分别为第一参考信号资源和第二参考信号资源，那么该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，且第一参考信号资源和第二参考信号资源对应同一个面板，第一参考信号资源和第二参考信号资源对应的面板数为1。如果面板信息为011，面板信息指示的第二参数为{2，2，2}，该第二参数指示的两个最大发送端口数分别为2和2，指示的面板数为2。表示该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，但是第一参考信号资源和第二参考信号资源对应不同的面板，第一参考信号资源和第二参考信号资源对应的面板数为2。其他情况可以以此类推，不再赘述。
上面的例子以面板信息为第二参数的索引为例，面板信息也可以为第二参数。例如，结合表16，如果面板信息为{2，1}，该面板信息指示的最大发送端口数为2。那么该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，且第一参考信号资源和第二参考信号资源对应同一个面板，即第一参考信号资源和第二参考信号资源对应的面板数为1。如果面板信息为{2，2，1}，该面板信息指示的两个最大发送端口数分别为2和2，表示该面板信息对应的资源组中的第一参考信号资源对应的面板的最大发送端口数为2，第二参考信号资源对应的面板的最大发送端口数为2，但是第一参考信号资源和第二参考信号资源对应不同的面板，即第一参考信号资源和第二参考信号资源对应的面板数为2。其他情况可以以此类推，不再赘述。
进一步的，如果终端设备上报的最大发送端口数为大于0的数，那么面板信息还用于指示与面板信息对应的资源组中的两个参考信号资源对应的一个或两个面板是否能够用于上行传输或上行多波束同传或上行多面板同传。例如，结合表16，面板信息为000～101时，用于指示一个第二参数，面板信息为110～111中的一个时，面板信息的对应资源组中 的两个参考信号资源中存在至少一个参考信号资源对应的最大发送端口数可能为0，不能用于上行同传。此时，若面板信息为110～111中的一个时，表示面板信息对应的资源组中的两个参考信号资源对应的一个或两个面板不能用于上行传输或上行多波束同传或上行多面板同传。
可选的，网络设备获取第一指示信息和第二指示信息之后，若调度终端设备进行上行同时传输，那么终端设备上行发送的两波束需要对应两个不同面板。网络设备根据终端设备上报的资源组关联的面板信息就可以确定哪些资源组对应两个面板，然后向终端设备发送上行发送波束指示，其中上行发送波束指示包含终端设备上行同传的两个上行发送波束的参考信号资源，这两个参考信号资源来自一个资源组，且对应两个不同的面板。
