具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
在介绍本申请之前，首先对本申请实施例中的部分用语进行简单解释说明，以便于本领域技术人员理解。
1)波束：
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，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。通过不同的波束可以发送相同的信息或者不同的信息。
可选地，可以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。一个波束可以对应一个或多个天线端口，用于传输数据信道，控制信道和探测信号等。例如，发射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。可以理解的是，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
在使用低频或中频频段时，可以全向发送信号或者通过一个较宽的角度来发送信号。而在使用高频频段时，得益于高频通信系统较小的载波波长，可以在发送端和接收端布置很多天线阵子构成的天线阵列，发送端以一定波束赋形权值发送信号，使发送信号形成具有空间指向性的波束。同时，在接收端用天线阵列以一定波束赋形权值进行接收，可以提高信号在接收端的接收功率，对抗路径损耗。
在协议中，一般采用TCI state ID，或SRI对波束进行标识。在一些可能的实现中，也通过参考信号资源标识，或同步信号索引，间接的表示波束。
2)准共址(quasi-co-location，QCL)：
QCL用于表示多个资源之间具有一个或多个相同或者相类似的通信特征。对于具有QCL关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口QCL，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。其中，大尺度特性可以包括：延迟扩展，平均延迟，多普勒扩展，多普勒频移，平均增益，接收参数，终端设备接收波束编号，发射/接收信道相关性，接收到 达角，接收机天线的空间相关性，主到达角(angel-of-arrival，AoA)，平均到达角，AoA的扩展等。
在应用时，可以利用同位指示来指示至少两组天线端口是否具有QCL关系。其中，利用同位指示来指示至少两组天线端口是否具有QCL关系可以理解为：同位指示用于指示至少两组天线端口发送的信道状态信息参考信号(CSI RS)是否来自相同的传输点，或同位指示用于指示至少两组天线端口发送的信道状态信息参考信号(CSI RS)是否来自相同的波束组。
3)传输配置指示(transmission configuration indicator，TCI)：
TCI是下行控制信息(downlink control information，DCI)中用于指示物理下行共享信道(physical downlink shared channel，PDSCH)天线端口的QCL关系的字段。
TCI可以由高层，如无线资源控制(radio resource control，RRC)层配置。在配置信令中TCI可以被称为TCI状态(TCI-state)，TCI-state是一个信息结构，其中包括波束相关的信息。在由RRC配置后，可以由基站发送媒体(介质)接入控制(medium access control，MAC)控制元素(control element，CE)(MAC-CE)以激活一个或多个TCI-state。基站可以进一步发送下行控制信息(downlink control information，DCI)指示多个被激活的TCI-state中的一个。
协议中的高层可以通过TCI-state来配置QCL，其中，TCI-state的参数可以用于在一到两个下行参考信号和PDSCH的解调参考信号(demodulation reference signal，DMRS)之间配置QCL关系。TCI可以包括一个或者两个QCL关系。由于QCL可以表征终端设备当前将要接收(或发送)的信号/信道，与之前已知的某参考信号之间的某种一致性关系，因此若存在QCL关系，终端设备可以继承之前接收(或发送)某参考信号时的参数，来接收(或发送)将要到来的信号/信道。
在应用时，如果TCI-state中包含标识为QCL Type-D的信息，则该TCI-state可以用于指示波束。如果TCI-state中包含的标识QCL Type-A、QCL Type-B或QCL Type-C的信息，则该TCI-state可以用于指示时域与频域偏移等信息(不包括空域信息)，一般用于辅助终端设备进行数据接收解调。在实现时，可以考虑当两个TCI状态配置采用了相同的QCL Type-D的源参考信号，则两个TCI状态具有QCL关系，或可以认为采用了相同的波束。
4)参考信号(reference signal，RS)：根据长期演进LTE/NR的协议，在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括随机接入信道(random access channel，PRACH)上行控制信道(physical uplink control channel，PUCCH)，上行数据信道(physical uplink shared channel，PUSCH)等，上行信号包括信道探测信号SRS，上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)，上行数据信道解调参考信号PUSCH-DMRS，上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)，上行定位信号(uplink positioning RS)等等。下行通信包括下行物理信道和下行信号的传输。其中下行物理信道包括广播信道(physical broadcast channel，PBCH)，下行控制信道(physical downlink control channel，PDCCH)，下行数据信道(physical downlink shared channel，PDSCH)等，下行信号包括主同步信号(primary synchronization signal，简称PSS)/辅同步信号(secondary synchronization signal，SSS)，下行控制信道解调参考信号PDCCH-DMRS，下行数据信道解调参考信号PDSCH-DMRS，相位噪声跟踪信号PTRS，信道状态信息参考信号(channel status information reference signal，CSI-RS)， 小区信号(Cell reference signal，CRS)(NR没有)，精同步信号(time/frequency tracking reference signal，TRS)(LTE没有)，LTE/NR定位信号(positioning RS)等。
为了提高频谱利用率，未来的基站部署将会更加密集。然而由于光纤的部署成本非常高昂，通过无线中继节点(relay node，RN)的回传链路与核心网建立连接，可节省部分光纤部署成本。
中继节点可以与一个或多个上级节点建立无线回传链路，并通过上级节点接入核心网。上级节点可通过多种信令对中继节点进行一定的控制(例如，数据调度、定时调制、功率控制等)。另外，中继节点可以与一个或多个下级节点建立连接，并为一个或多个下级节点提供服务。中继节点的上级节点可以是基站，也可以是另一个中继节点。中继节点的下级节点可以是终端，也可以是另一个中继节点。在某些情形下，上级节点也可以称为上游节点，下级节点也可以称为下游节点。
为了提高频谱的利用率，回传链路和接入链路可共享相同频段，该方案也称为带内中继。带内中继一般具有半双工的约束，也就是中继节点在接收其上级节点发送的下行信号时不能向其下级节点发送下行信号，且中继节点在接收其下级节点发送的上行信号时不能向其上级节点发送上行信号。新一代无线通信系统(new radio，NR)的带内中继方案被称为IAB，相应的，中继节点被称为IAB节点(IAB node)。
图1示出了一种IAB系统，IAB节点(可认为是无线回传设备)为终端提供无线接入和接入业务的无线回传。IAB donor节点(IAB宿主节点，可认为是宿主基站)向IAB节点提供无线回传功能，并提供终端与核心网的接口。IAB节点通过无线回传链路连接到IAB donor节点，从而使IAB节点所服务的终端与核心网进行连接。
需要说明的是，在如图1所示的网络架构图中，尽管示出了终端侧设备、无线回传设备及宿主基站，但该网络架构可以并不限于包括终端侧设备、无线回传设备及宿主基站。例如，还可以包括核心网设备或用于承载虚拟化网络功能的设备等，这些对于本领域普通技术人员而言是显而易见的，在此不一一详述。另外，如图1所示的系统中，尽管示出了一个终端侧设备、一个无线回传设备及一个宿主基站，但该网络架构并不限制终端侧设备、无线回传设备及宿主基站的数量，例如，也可以包括多个终端侧设备、多个无线回传设备及多个宿主基站等。在下文的描述中，以无线回传设备是IAB节点为例。
donor节点是指通过该节点可以接入到核心网的节点，或者是无线接入网的网络设备，例如为锚点基站(或上文提到的宿主基站、宿主节点)，通过该锚点基站可以接入到网络。锚点基站负责分组数据汇聚协议(packet data convergence protocol，PDCP)层的数据处理，或者负责接收核心网的数据并转发给中继节点，或者接收中继节点的数据并转发给核心网。Donor节点一般可以通过有线的方式连接到网络，例如光纤线缆。
网络设备可以称为基站，又可以称为无线接入网(radio access network，RAN)节点(或设备)。示例的，网络设备可以为下一代节点B(next-generation Node B，gNB)、传输接收点(transmission reception point，TRP)、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(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。本申请实施例中网络设备的名称可以是中 继节点(RN)，中继发送接收点(rTRP)，IAB节点(IAB node)等；中继节点的上级节点可以是gNB(包括gNB-DU，gNB-CU等)，也可以是另一个中继节点。
示例性的，本申请实施例中的网络设备可以划分为集中单元(centralized unit，CU)和至少一个分布式单元(distributed unit，DU)。其中，CU和DU是相对而言的，CU可以用于管理或者控制至少一个DU，也可以称之为CU与至少一个DU连接。这种结构可以将通信系统中网络设备的协议层拆开，其中部分协议层放在CU集中控制，剩下部分或全部协议层功能分布在DU中，由CU集中控制DU。以网络设备为gNB为例，gNB的协议层包括无线资源控制(radio resource control，RRC)层、业务数据适配协议(service data adaptation protocol，SDAP)层、分组数据汇聚协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体访问控制子层(media access control，MAC)层和物理层(physical layer，PHY)。其中，示例性的，CU可以用于实现RRC层、SDAP层和PDCP层的功能，DU可以用于实现RLC层、MAC层和物理层的功能。CU与DU物理上可以通过光纤连接，逻辑上存在一个专门定义的F1接口，用于CU与DU之间进行通信。从功能的角度，CU主要负责无线资源控制与配置，跨小区移动性管理，承载管理等；DU主要负责调度，物理信号生成与发送。本以CU向DU发送配置(类似下行传输方向)为例，CU生成的F1-AP数据包被封装成IP包，在空口多跳节点之间传递。数据包到达目标IAB节点后，在目标IAB MT适配层处理后，将数据包转给本地IAB DU模块进行处理，最终在DU解析到F1-AP数据包。本申请实施例不对CU、DU包括的协议栈做具体限定。
图2示出了IAB节点的一种结构示意图。NR中的IAB节点可分为移动终端(mobile termination，MT)与DU两部分。MT也可以理解为在IAB节点中类似终端的一个组件。DU是相对网络设备的集中单元(centralized unit，CU)功能而言的。因此，也可认为IAB节点包括MT功能和DU功能，为了描述简便，在下文中，将MT功能称为MT，将DU功能称为DU。由于MT类似一个普通终端的功能，那么可以理解为MT用于IAB节点与上级节点(父节点)通信。DU是相对网络设备的集中单元(centralized unit，CU)功能而言的，DU用于IAB节点与下级节点(子节点)通信。应理解，上级节点可以是基站或者其他IAB节点，下级节点可以是终端或者其他IAB节点。MT与上级节点通信的链路称为上级回传链路(parent BackHaul link)，DU与下级IAB节点通信的链路称为下级回传链路(child BackHaul link)，而DU与下属终端通信的链路称为接入链路。在一些实施例中，下级回传链路也被称为接入链路，其中，上级回传链路包括上级回传上行链路(uplink，UL)以及上级回传下行链路(downlink，DL)，下级回传链路包括下级回传UL和下级回传DL，接入链路包括接入UL和接入DL，如图3所示。
若网络设备是中继设备，尤其是IAB节点时，网络设备可以包括MT功能和DU功能。即IAB节点通过MT与上级节点进行通信，DU是IAB节点的基站功能模块，用于实现RLC层、MAC层和物理层的功能，主要负责调度、物理信号生成与发送，即IAB节点通过DU与下级节点和终端进行通信，如图4所示。IAB节点的MT与DU均具有完整的收发模块，且两者之间具有接口。但应注意，MT与DU为逻辑模块，在实际中，两者可以共享部分子模块，例如可共用收发天线，基带处理模块等，如图4所示。
在IAB节点正常工作时，接入链路与回传链路(也就是MT与DU)以时分多路复用(time-division multiplexing，TDM)，空分多路复用(space division multiplexing，SDM) 或频分多路复用(frequency-division multiplexing，FDM)的方式进行资源复用。回传链路与接入链路在不同的时刻工作即为TDM模式；在同一时间，接入链路与回传链路上仅接收或发送，那么回传链路与接入链路的工作模式为SDM模式；在同一时间，接入链路或回传链路上既接收，也发送，那么回传链路与接入链路的工作模式为全双工模式。通常来说，由于全双工传输需要额外考虑自身发送信号对自身接收信号的影响，全双工模式对硬件要求更高。
以TDM场景为例，回传链路与接入链路在不同的时刻工作，因此IAB节点需要在回传链路的收发与接入链路的收发之间切换。当回传与接入链路无间隔切换时，即接入链路符号与回传链路符号连续时，IAB节点具有较高的资源利用率。然而在实现中，由于功放的开关时间，传输距离，非理想同步等各种因素，回传链路与接入链路无法实现无间隔切换。此时，IAB节点需要确定回传链路和接入链路的可用/不可用符号集合。
为此，可配置MT资源和DU资源。MT资源可被配置为下行(downlink，D)，上行(uplink，U)，灵活(Flexible，F)三种类型。下行表示资源用于下行传输，上行表示资源用于上行传输，灵活表示MT的传输方向依赖于上级节点的进一步指示(一般通过物理层信令动态指示)。DU资源也可被配置为上行，下行，灵活三种类型，表示三种传输方向。进一步的，DU资源的上行资源，下行资源和灵活资源还可分为hard和soft两类。其中，DU hard资源表示DU始终可用的资源；DU soft资源表示DU是否可用该资源，依赖于上级节点的指示。DU还有一种不可用(NA，Not Available)资源类型，表示DU始终不可使用该资源。
可见，MT资源具有3种类型，DU资源具有7种类型，根据MT资源配置和DU资源配置可确定IAB节点的资源配置。例如，可以通过F1-AP接口信令在CU与DU之间进行传递DU的资源类型以及相应的传输方向。如在TS 38.473 9.2.9.3中定义的“GNB-DU RESOURCE CONFIGURATION”包括“gNB-DU Cell Resource Configuratio”实现了对DU资源的具体配置。
其中，“gNB-DU Cell Resource Configuratio”中的“DUF Slot Configuratio ltem”用于配置DU的传输方向，包括上行，下行和灵活。“gNB-DU Cell Resource Configuratio”中的“HSNA Slot Configuratio list”相关配置用于配置DU资源的属性(hard，soft，not available)。
进一步地，为了确定IAB DU上soft资源的可用性，上级节点可通过发送DCI 2_5进行指示。例如，IAB节点的多个上级节点可分别对可调度的DU soft资源进行指示。以图5为例，上级节点1和上级节点2分别获取IAB节点中DU上的多个小区的soft资源，上级节点1和上级节点2基于DCI 2_5指示DU上的多个小区中的具体哪些小区的哪些soft资源可用。当一个下行、上行或灵活的符号被配置为hard时，DU可以分别在符号中发送或接收，要么发送或接收。当一个下行、上行或灵活的符号被配置为soft时，DU可以只能在符号中发送或接收，要么发送或接收。例如IAB的MT在符号中不发送或不接收；又例如，IAB的MT在符号中接收或发送，但是不会改变IAB的DU在符号中的发送或接收；又例如，IAB的MT检测到DCI 2_5，且指示DU soft资源可用。应理解，当一个符号被配置不可用，那么IAB的DU在该符号既不发送也不接收。
前述介绍了如图1所示的网络架构中的IAB节点的资源配置方法。然而，在一种可能的应用场景中，如图5所示，为IAB节点双连接的网络架构的示意图。IAB节点双连接指的是为IAB节点提供无线回传链路资源的节点为2个，也就是IAB节点具有两个上级节点。 图5以2个上级节点为上级节点1和上级节点2为例。当然，图5中的上级节点可以是其他IAB节点，也可以是donor节点，还可以是普通基站。如果上级节点是IAB节点，那么上级节点也可以包括MT功能和DU功能。如果上级节点是donor节点，那么上级节点也可以包括CU功能和DU功能。
针对IAB节点双连接的场景来说，如果沿用目前的IAB节点的资源配置方法，即多个上级节点可分别对可调度的DU soft资源进行指示，也就是，多个上级节点独立地对可调度的DU soft资源进行指示。多个上级节点可以在同一资源或不同资源上调度IAB节点，但是多个上级节点并不知道彼此对哪些可调度的DU soft资源进行指示，这样会导致DU soft资源分区效率低下。例如，多个上级节点在不同的多个DU soft资源上调度IAB，多个DU soft资源无重叠(无交集)，那么实际可用于IAB-DU的资源会非常有限，这会降低IAB节点的频谱效率，甚至会造成IAB节点处发生数据堵塞。
为了便于理解，请参见图6，为IAB节点的两个上级节点为IAB节点指示可用资源的示意图。图6以可调度的资源从左到右依次为1个hard资源、2个soft资源、2个hard资源、4个soft资源以及1个hard资源。在图6中，“S”表示soft资源，“H”表示hard资源。以上级节点为IAB节点指示可用的soft资源为例，IAB节点的DU上所有soft资源都有至少一个上级节点不指示是否可用。下文主要以soft资源为例，为了便于描述，可称为处于左侧的2个soft资源为soft资源1，处于右侧的4个soft资源称为soft资源2。如图6所示，上级节点1可指示soft资源1可用，不指示soft资源2是否可用；上级节点2不指示soft资源1是否可用，指示soft资源2可用。即IAB节点的所有Soft资源都有至少一个上级节点不指示可用，也就是上级节点1指示的可用soft资源和上级节点2指示的可用soft资源无交集或者交集很少，这种情况下，IAB节点的DU剩余可用的soft资源较少，容易造成IAB节点处发生数据堵塞。
为此，在本申请实施例中，可协调多个上级节点之间的资源，例如，多个上级节点在可能的情况下使用重叠的资源调度IAB节点，以使得剩余更多实际可用于IAB-DU的资源，尽量提高IAB节点的频谱效率，避免IAB节点处发生数据堵塞。
示例性的，本申请实施例提供了一种IAB节点的资源配置方法，该方法中，宿主节点配置优先级不同的一个或多个资源集合，并告知IAB节点的多个上级节点。各个上级节点可根据各个资源集合的优先级，优先选择优先级较高的资源调度IAB节点进行传输。由于优先级较低的资源没有优先被指示，这样较低优先级资源可作为IAB节点后续可用的资源，即为IAB节点的DU剩余更多的可用资源，可尽量减少数据发生堵塞的现象。
本申请实施例提供的通信方法可以应用于具有中继节点的双连接的通信系统，如图5所示。应理解，图5仅是一种示例性说明，并不对无线通信系统中包括的终端设备、中继节点的数量进行具体限定。在LTE中，中继节点一般被称为RN。在NR中，中继节点一般被称为IAB节点。在一些实施例中，中继节点也可以称为中继设备，或者中继传输接收点(relay transmission and receptio point，rTRP)，中继节点的上级节点可以是网络设备(包括网络设备的DU，或者包括网络设备的CU等)。
应理解，本申请实施例中采用IAB节点仅仅出于描述的需要，并不表示本申请实施例的方案仅用于NR的场景，在本申请实施例中，IAB节点可以泛指任何具有中继功能的节点或设备，本申请实施中的IAB节点和中继节点的使用应理解具有相同的含义。

作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化实现方式、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。当然，本申请实施例中的终端也可以是车辆。或者本申请实施例中的终端也可以是物联网终端，例如智能家电，例如智能水表或智能电表等；又例如路测设备等。这里的路测设备可以包括智能路灯、路边智能摄像头等。
下面结合附图对本申请实施例提供的资源配置方法进行详细介绍。
请参见图7，为本申请实施例提供的资源配置方法的流程图。
在下文的介绍过程中，以该方法应用于图5所示的通信系统为例。另外，该方法可由三个通信装置执行，这三个通信装置例如为第一通信装置、第二通信装置和第三通信装置。
为了便于介绍，在下文中，以该方法由IAB节点、宿主节点和上级节点执行为例，也就是，以第一通信装置是IAB节点、第二通信装置是上级节点，第三通信装置是宿主节点为例。其中，上级节点可以是基站，也可以是其他IAB节点，在下文中以上级节点是基站为例。其中，所述基站可以是具有宿主节点功能的基站。
需要说明的是，本申请实施例只是以通过图5的通信系统为例，并不限制于这种场景。应理解，宿主节点指的是IAB节点当前所连接的宿主基站。上级节点指的是IAB节点当前 连接的基站或其他IAB节点。
具体的，本申请实施例提供的资源配置方法的流程描述如下。
S700、中继节点获取第一信息。
本申请实施例中该第一信息包括至少一个用于发送第一信号的上行波束的标识。其中，该第一信号包括SRS。可以理解的，所述上行波束为所述中继节点中的MT向所述上级节点进行通信的波束。
其中，该第一信号还可以包括CSI-RS和SSB。可以理解在这种情况下，中继节点利用自身发送下行信号的波束，作为第一信号的波束标识，所述波束为所述中继节点中的DU发送的波束，但可以被上级节点测量和识别并标识。下文以第一信号为SRS，波束为上行波束作为示例进行阐述。
可选的，该第一信息是该中继节点从Donor获取的。
作为一种示例，Donor为该中继节点配置SRS的资源时，假设Donor需要为3个SRS配置资源。其中，中继节点使用SRS1资源配置发送SRS信号时采用的波束为波束1，中继节点使用SRS2资源配置发送SRS信号时采用的波束为波束2，中继节点使用SRS3资源配置发送SRS信号时采用的波束为波束3。因此，该第一信息可以包括SRS与波束的标识的对应关系。例如，该第一信息可以包括下述表1的对应关系。其中SRS资源的标识有时也称为SRI(SRS resource indicator)。
SRS资源的标识 波束
SRS1 波束1
SRS2 波束2

其中，本申请实施例中该第一信息还可以包括该第一信号与配置情况的关联关系，从而可以使所述中继节点根据该第一信号与配置情况的关联关系，确定该第一信号对应的波束的传输配置；或者，该第一信息还可以包括该波束与配置情况的关联关系，从而可以使该中继节点根据该波束与配置情况的关联关系，确定该波束的传输配置0。
可选的，本申请实施例中的配置情况根据该宿主节点根据对至少一个配置参数的设置确定的。
可选的，该配置参数包括下列信息中的一个或多个：
信息1：进行通信传输时频段间保护带设置情况，可以表示当中继节点的MT和DU进行频分复用时，是否需要保护带。
信息2：保护带大小，表示在中继节点的接入与回传进行频分复用时，MT与DU所使用的频域资源之间预留频域资源的大小，所述预留频域资源不被MT或DU所使用。
示例性的，所述保护带的大小可以通过物理资源块(PRB，physical resource block)的个数进行表示。

信息6：该中继节点中的移动终端MT的下行接收功率区间设置情况，表示中继节点在进行空分接收时，MT期望的下行发送功率的范围或调整量，例如在当前上级节点下行传输信号的功率基础上，降低X dB。
信息7：该中继节点中MT的下行调度的解调参考信号DMRS端口的最大数量。
信息8：该中继节点中MT的上行调度的DMRS端口的最大数量。
例如，宿主基站或者中继节点的上级节点可以利用信令配置多组配置参数，每组配置参数包括上述信息中的一个或多个。每组参数可以用一个ID进行标识，如下所示结构：
Figure PCTCN2022123085-appb-000001
上述参数也可以是中继节点上报给上级节点或Donor节点，即上报中继节点期望的参数后，再由上级节点或Donor节点配置给中继节点的。
中继节点的上级节点还可以通过DCI信令，或者MAC-CE信令，进一步指示一个参数集合ID，用于指示中继节点生效的参数集合。在所述指示的参数集合生效后，中继节点在预配置的空分传输时间资源上，根据参数集合所指示的参数，进行空分传输。
需要说明的是，上述信元的名称仅为示例性的，实现中可以被替换为其他实现等效功能的其他名称，本申请不做限定。
S701、该中继节点根据该第一信息确定第二信息。
本申请实施例中该第二信息包括该上行波束与期望的PSD的对应关系。
本申请实施例中该PSD是指上行发送信号的PSD范围，简称PSD。
其中，本申请实施例中该第二信息包括的内容形式多样，具体并不限于下述几种：
内容1：本申请实施例中该第二信息中包括的上行波束对应一个PSD。
其中，需要说明的是，本申请实施例中该上行波束与PSD的对应关系具体可以根据实际情况进行关联。
示例性的，假设中继节点接收到的第一信息中指示的上行波束包括上行波束1～4。该中继节点分别为每个上行波束确定对应的期望PSD。
其中，如图8中的(a)所示，例如中继节点为上行波束1确定的期望PSD为PSD1，中继节点为上行波束2确定的期望PSD为PSD2，中继节点为上行波束3确定的期望PSD为PSD2，中继节点为上行波束4确定的期望PSD为PSD3。因此，该中继节点向上级节点发送的第二信息的内容可以为上述图8(a)所示的内容。
再例如，如图8中的(b)所示，例如中继节点为上行波束1确定的期望PSD为PSD1，中继节点为上行波束2确定的期望PSD为PSD2，中继节点为上行波束3确定的期望PSD为PSD1，中继节点为上行波束4确定的期望PSD为PSD2。因此，该中继节点向上级节点发送的第二信息的内容可以为上述图8(b)所示的内容。
其中，根据上述图8所述的内容，可以理解，本申请实施例中该第二信息中的对应关系可以为波束以及与该波束关联的PSD的信息，也可以为PSD以及与该PSD关联的波束的信息，表现形式多样，在此并不进行限定。
内容2：本申请实施例中该第二信息中包括的上行波束中的一个或多个波束可以对应多个PSD。
其中，需要说明的是，本申请实施例中该上行波束与PSD的对应关系具体可以根据实际情况进行关联。
可选的，本申请实施例可以基于一个波束的不同配置情况，分别设置对应的期望PSD，从而可以使上级节点根据波束不同配置情况，设置该波束的发送功率。
例如，下面的表2示例了一种对应的情况。其中，参数配置包括但不限于示例中的频分与否的状态以及保护带的大小；期望的PSD范围的表示形式包括但不限于示例中的情况，还可以仅包括下限，或同时包括上限和下限；PSD的范围还可以体现为上行发送的标称功率P0和或偏移值。
Figure PCTCN2022123085-appb-000002
表2波束配置情况示例
示例性的，假设中继节点接收到的第一信息中指示的上行波束包括上行波束1～2。该中继节点分别为每个上行波束基于配置情况1～3分别确定对应的期望PSD。
其中，如图9中的(a)所示，例如，当上行波束1的配置情况为配置情况1时，中继节点为上行波束1确定的期望PSD为PSD1，当上行波束1的配置情况为配置情况2时，中继节点为上行波束1确定的期望PSD为PSD3，当上行波束1的配置情况为配置情况3时，中继节点为上行波束1确定的期望PSD为PSD2。
当上行波束2的配置情况为配置情况1时，中继节点为上行波束2确定的期望PSD为PSD4，当上行波束2的配置情况为配置情况2时，中继节点为上行波束2确定的期望PSD为PSD3，当上行波束2的配置情况为配置情况3时，中继节点为上行波束2确定的期望PSD为PSD1。因此，该中继节点向上级节点发送的第二信息的内容可以为上述图9(a)所示的内容。
再例如，如图9中的(b)所示，例如中继节点为上行波束1在配置情况1确定的期望PSD为PSD1，为上行波束1在配置情况2确定的期望PSD为PSD2，为上行波束1在配置情况3确定的期望PSD为PSD3。
中继节点为上行波束2在配置情况1确定的期望PSD为PSD3，为上行波束2在配置情况2确定的期望PSD为PSD1，为上行波束2在配置情况3确定的期望PSD为PSD2。 因此，该中继节点向上级节点发送的第二信息的内容还可以为上述图9(b)所示的内容。
其中，根据上述图9所述的内容，可以理解，本申请实施例中该第二信息中的对应关系可以为波束，配置情况以及与该波束关联的PSD的信息，也可以为PSD，配置情况以及与该PSD关联的波束的信息，表现形式多样，在此并不进行限定。
内容3：本申请实施例中该第二信息中包括的用于配置上行波束的参数集合可以对应一个多个PSD。
其中，该内容3可以理解为配置参数也可以与波束直接进行结合，例如宿主基站或者中继节点的上级节点可以利用信令为某个波束配置多组参数集合，每组参数集合包括上述表示配置参数的信息1～信息8中的一个或多个。其中，每组参数集合可以用一个ID进行标识。
示例性的，参数集合如下所示结构：
Figure PCTCN2022123085-appb-000003
可选的，本申请实施例可以基于不同的参数集合分别设置对应的期望PSD范围，从而 可以使上级节点根据波束的不同配置情况，设置该波束的发送功率。
示例性的，假设该参数集合与期望PSD范围的对应关系如下表3所示：
Figure PCTCN2022123085-appb-000004
表3参数集合与PSD范围的对应关系
假设，当该波束1可以采用参数集合1～参数集合3分别进行配置，其中，中继节点向上级节点发送的第二信息中指示了参数集合与期望PSD的对应关系，即上述表3的内容，因此，上级节点确定该波束1采用参数集合2进行配置时，根据表3的内容可知，对应的上行PSD上限为15dBm。从而，可以基于该PSD(即上行PSD上限为15dBm)确定该波束1在采用参数集合2进行配置情况下对应的发送功率。
需要说明的是，本申请实施例中该参数集合与PSD范围的对应关系具体可以根据实际情况进行关联。
其中，本申请实施例中配置的参数集合中，可以不包括波束的标识，或者不包括上行功率PSD范围，或者不包括波束标识和上行功率PSD范围。
进一步的，本申请实施例中的中继节点的上级节点还可以通过DCI信令，或者MAC-CE信令，进一步指示一个参数集合与波束标识和/或功率PSD范围的关联关系。例如，上级节点发送MAC-CE信令，如下表4所示：
Figure PCTCN2022123085-appb-000005
可选的，上述表4中的一行可以为MAC-CE信令中的一个8比特序列长度。其中，这里仅示例了MAC-CE所包括的内容，根据表4所述，应理解，所述MAC-CE所包括的内容可以不止于此。
此外，上述方法也可以通过不将波束标识或上行功率PSD范围进行动态指示，而将不进行预配置的参数集合中的其他参数进行动态指示来实现，此时，波束标识或PSD范围可以作为配置参数的一部分进行预配置，具体哪些参数(参数组合)通过上级节点动态指示来确定，在此不再赘述。
S702、中继节点向上级节点发送该第二信息。
S703、上级节点获取该第二信息。
S704、上级节点根据该第二信息，确定第三信息，所述第三信息用于指示所述中继节点基于所述波束发送信息确定发送功率。
可选的，本申请实施例中该发送信息可以包括控制信道的数据，数据信道的数据以及SRS，例如，用该波束基于该第三信息指示的该波束对应的发送功率传输数据，或者SRS。
S705、上级节点向中继节点发送第三信息。
S706、中继节点接收该第三信息。
通过该方法，上级节点能够更灵活，准确的配置波束的发送功率，有效降低通信干扰。
进一步的，本申请实施例中为了减少对下行波束通信传输的不必要影响，本申请实施例中上级节点还可以指示中继节点该上行波束与下行波束的限制关系，从而当上级节点采用该上行波束进行传输时，仅需限制对应的下行传输波束，不需要限制所有下行波束，有效减少了对下行波束通信传输的影响。
具体的，如图10所示，本申请实施例提供另一种资源配置方法的流程描述如下。
S1000、上级节点确定第四信息，所述第四信息中包括上行波束与下行波束的限制关系。
可选的，本申请实施例中该上级节点可以在接收到来自上述实施例中的中继节点发送的第二信息之后，确定该第四信息。
可选的，该第四信息可以是该上级节点根据接收到的该第二信息确定的。
S1001、上级节点向中继节点发送该第四信息。
可选的，本申请实施例中，该第四信息可以携带在上述实施例中的第三信息中，也可以单独发送，发送方式以及发送时机本申请实施例在此不进行限定。
S1002、中继节点接收该第四信息。
S1003、中继节点采用第一波束进行通信传输时，根据该第四信息，限制使用该第一波束对应的下行波束。
示例性的，假设该第四信息中包括的上行波束与下行波束的限制关系如下表5所示：
上行波束的标识 下行波束的标识
上行波束1 下行波束1，5，4
上行波束2 下行波束2，3
上行波束3 下行波束4，6
表5上行波束与下行波束的限制关系
假设，当中继节点采用上行波束1进行通信传输时，此时下行波束有下行波束1～10。中继节点根据上述表2的内容，可以从下行波束1～10中选择下行波束1，5，4进行限制。
此外，本申请实施例中用于确定需要限定的下行波束的方式有多种，并不限于上述表4所示的内容，任何可以应用到本申请实施例的映射关系等内容都可以用于确定需要限定的下行波束，例如，本申请实施例还可以基于参数配置集合与需要限定的下行波束的对应关系，确定该需要进行限定的下行波束。
其中，假设第四信息中包括参数配置集合与下行波束的限制关系如下表6所示：
参数集合标识 限制的下行波束标识
参数集合1 下行波束1，5，4
参数集合2 下行波束2，3
参数集合3 下行波束4，6
表6参数集合标识与下行波束的限制关系
因此，当中继节点确定应用的上行波束采用参数集合1进行配置时，中继节点根据上述表5的内容，确定对下行波束1，5，4进行限制。
进一步的，本申请实施例中，为了避免因对下行波束的限制，导致应用该下行波束进行传输的优先级较高的业务受到影响，本申请实施例中该中继节点还可以在确定满足第一条件时，停止对该下行波束的限制。
具体的，如图11所示，本申请实施例提供另一种资源配置方法的流程描述如下。
S1100、中继节点采用第一波束进行通信传输时，根据该第四信息，限制使用该第一波束对应的下行波束。
S1101、中继节点判断是否满足第一条件，若是，执行S1102，若否，执行S1100。
