Description

一种资源调度的方法和装置
本申请要求于2018年7月5日提交中国国家知识产权局、申请号为201810731379.1、发明名称为“一种资源调度的方法和装置”的中国专利申请的优先权；要求于2018年11月2日提交中国国家知识产权局、申请号为201811302743.9、发明名称为“一种资源调度的方法和装置”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
本申请涉及通信领域，并且更具体地，涉及一种资源调度的方法和装置。
背景技术
随着移动通信技术的不断发展，频谱资源日趋紧张。为了提高频谱利用率，未来的基站部署将会更加密集。此外，密集部署还可以避免覆盖空洞的出现。在传统蜂窝网络架构下，基站通过光纤与核心网建立连接。然而在很多场景下，光纤的部署成本非常高昂。无线中继节点(relay node,RN)通过无线回传链路与核心网建立连接，可节省部分光纤部署成本。
一般情况下，中继节点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，中继节点可为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。
中继节点与上级节点进行通信的链路被称为回传链路，而与下级节点通信的链路被称为接入链路。回传链路与接入链路处于同一频段的中继节点被称为带内中继。为保证带内中继的正常工作，上级节点需为其配置回传资源。一般情况下，回传资源由无线控制资源(radio resource control，RRC)等高层信令半静态配置，而后上级节点进一步通过下行控制信息(downlink control information，DCI)等信令动态配置回传链路的调度参数。在长期演进(long term evolution，LTE)系统中上级节点通过半静态配置回传资源，上级节点无法根据回传链路的数据量的变化动态调整实际调度的回传资源的数目，这样可能会导致系统灵活性差。

图1示出了本申请涉及的无线通信系统。所述无线通信系统可以是长期演进(long term evolution，LTE)系统，也可以是未来演进的第五代移动通信(the 5th Generation，5G)系统、新空口(NR)系统，机器与机器通信(machine to machine，M2M)系统等。如图1所示，无线通信系统100可包括：网络设备101，终端105，以及中继设备103。无线通信系统100包括单跳中继系统或者多跳中继系统。在多跳中继系统中，参见图1所示，网络设备101和终端105之间至少有两个中继设备103。而在单跳中继系统中，网络设备101和终端105之间只有一个中继设备103。
网络设备可以用于与一个或多个终端进行通信，也可以用于与一个或多个具有部分终端功能的网络设备进行通信(比如宏基站与微基站，如接入点，之间的通信)。网络设备可以是时分同步码分多址(time division synchronous code division multiple access，TD-SCDMA)系统中的基站收发台(base transceiver station，BTS)，也可以是LTE系统中的演进型基站(evolutional node B，eNB)，以及5G系统、新空口(NR)系统中的基站gNB。另外，网络设备也可以为接入点(access point，AP)、传输节点(trans TRP)、中心单元(central unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。
本申请实施例涉及的终端(terminal)，可以是指向用户提供语音和/或数据连通性的设备，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。终端105可以是静止的，也可以是移动的。例如，终端105可以是移动设备、移动台(mobile station)、移动单元(mobile unit)、M2M终端、无线单元，远程单元、用户代理、移动客户端、手持设备、智能手表、笔记本电脑、平板电脑或智能手环等。
中继设备可以是中继基站，例如微基站等。中继设备也可以是一个提供中继功能的终端。中继设备还可以是中继收发节点，用户终端设备(customer premise equipment，CPE)，中继收发器、中继代理，传输接收点(transmission and reception point，TRP)，或者中继传输接收点(relaying TRP，rTRP)等网络实体。具体实现中，中继设备可以分布在小区边缘，可扩大网络设备的覆盖范围。
在无线通信系统100中，接入链路(access link)是指中继设备与终端之间的无线链路。该接入链路包括上行(uplink，UL)和/或下行(downlink，DL)接入链路。回传链路(backhaul link，BH)是指网络设备与中继设备之间的无线链路，或者中继设备和中继 设备之间的链路。该回传链路包括上行和/或下行回传链路。
在无线通信系统100中，网络设备101和终端105之间的中继设备103可用于对网络设备101和终端105之间的无线信号进行转发。具体的，在下行传输时，这中继设备103负责对网络设备101发射的无线信号进行转发，最终传输该无线信号至终端105。如果包含在上行传输时，中继设备103负责对终端105发射的无线信号进行转发，最终传输该无线信号至网络设备101。
需要说明的，图1示出的无线通信系统100仅仅是为了更加清楚的说明本申请的技术方案，并不构成对本申请的限定，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，本申请提供的技术方案对于类似的技术问题，同样适用。
如图2所示，为本申请实施例提供的一种网络设备的结构示意图，该网络设备可以包括基带处理单元(building baseband unit，BBU)201和远端射频模块(remote radio unit，RRU)202，RRU 202和天馈系统203连接，BBU 201和RRU 202可以根据需要拆开使用。比如，RRU可以拉远，位于一个云平台中。其中，图2所示的结构可以是网络设备的结构，也可以是中继设备的结构。BBU 201用于实现整个网络设备或中继设备的操作维护，实现信令处理、无线资源管理、以及到分组核心网的传输接口，实现物理层、介质接入控制层、L3信令、操作维护主控功能。RRU 202用于实现基带信号与射频信号之间的转换，实现无线接收信号的解调和发送信号的调制和功率放大等。天馈系统203可包括多个天线，用于实现无线空口信号的接收和发送。本领域人员可以理解的是，在具体实现过程中，网络设备还可以采用其他通用的硬件结构，而并非仅仅局限于图2所示的硬件结构。网络设备中涉及本申请实施例的功能也可以通过云接入网(CloudRAN)设备来实现，该CloudRAN可以采用分布式组网方式或者集中式组网方式、或者是上述两种组网方式的组合。
网络设备和中继设备或者终端之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol，SDAP)层。
这些协议层的功能可以由一个节点实现，或者可以由多个节点实现；例如，在一种演进结构中，网络设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
网络设备可以由一个节点实现无线资源控制(radio resource control，RRC)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、和媒体接入控制(media access control，MAC)等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，网络设备可以包括CU和DU，多个DU可以由一个CU集中控制。CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
进一步地，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
CU产生的信令可以通过DU发送给中继节点或者终端，或者，中继节点或者终端产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端或CU。以下实施例中如果涉及这种信令在DU和终端之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给中继节点或者终端，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频发送的。
本申请实施例中，网络设备可以是5G中的gNB(包括gNB-CU，gNB-DU)等。
根据现有协议，5G中的中继节点也被称为一体化接入回传(integrated access and backhaul，IAB)节点，IAB节点可分为层三IAB节点和层二IAB节点两种类型。其中层二IAB节点具有移动终端(mobile-termination，MT)与DU两种功能：MT功能用于IAB节点与上级节点的通信，而DU功能则用于IAB节点与下级节点的通信。类似的，层三IAB节点也分别具有与上级节点通信的功能和与下级节点通信的功能。
在本申请实施例中，一个节点至另一个节点(例如上级节点至中继节点，中继节点至另一中继节点等)的消息至少可通过以下两类方式进行发送和接收：
1)空口信令，例如RRC信令，媒体接入控制控制元素(medium access control control element，MAC CE)，DCI，上行控制信息(uplink control information，UCI)等；
2)网络设备之间或网络设备内部模块之间的接口，例如5G接入网节点之间的Xn接口，CU和DU之间的F1接口，CU与IAB节点DU功能之间的增强的F1接口，不同IAB节点之间的接口等。
应理解，本申请不对承载各类消息的信令或接口加以具体限制。
如图3所示，为本申请实施例提供的一种终端的结构示意图，以终端是手机为例，手机可以包括：射频(radio frequency，RF)电路310、存储器320、其他输入设备330、显示屏340、传感器350、音频电路360、I/O子系统370、处理器380、以及电源390等部件。下面结合图3对手机的各个构成部件进行具体的介绍：
其中，处理器380分别与RF电路310、存储器320、音频电路360、以及电源390均连接。I/O子系统370分别与其他输入设备330、显示屏340、传感器350均连接。其中，RF电路310可用于收发语音或数据信息，特别地，将网络设备的下行信息接收后，给处理器380处理。存储器320可用于存储软件程序以及模块。处理器380通过运行存 储在存储器320的软件程序以及模块，从而执行手机的各种功能应用以及数据处理。其他输入设备330可用于接收输入的数字或字符信息，以及产生与手机的用户设置以及功能控制有关的键信号输入。显示屏340可用于显示由用户输入的信息或提供给用户的信息以及手机的各种菜单，还可以接受用户输入，显示屏340可以包括显示面板341和触摸面板342。传感器350可以为光传感器、运动传感器或者其他传感器。音频电路360可提供用户与手机之间的音频接口。I/O子系统370用来控制输入输出的外部设备，外部设备可以包括其他设备输入控制器、传感器控制器、显示控制器。处理器380是手机的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器320内的软件程序和/或模块，以及调用存储在存储器320内的数据，执行手机的各种功能和处理数据，从而对手机进行整体监控。电源390(比如电池)用于给上述各个部件供电，优选的，电源可以通过电源管理系统与处理器380逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗等功能。
尽管未示出，手机还可以包括摄像头、蓝牙模块等功能模块或器件，在此不再赘述。本领域技术人员可以理解，图3中示出的手机结构并不构成对手机的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
中继设备可以是中继基站，例如微基站，或者是提供中继功能的终端。中继设备的结构可以参照网络设备或终端的结构示意图。
为了便于说明，对本申请中出现的词语进行说明。
第一节点为从网络设备到终端的链路上第二节点的上一跳设备、上级节点或者上游节点。第二节点为从网络设备到终端的链路上第一节点的下一跳设备、下级节点或者下游节点。第二节点为从网络设备到终端的链路上第三节点的上一跳设备、上级节点或者上游节点，或者为第三节点的同级节点。
或者第三节点为从网络设备到终端的链路上第二节点的下一跳设备、下级节点或者下游节点，或者为第二节点的同级节点。第一节点可以为网络设备或者中继设备，第二节点可以为中继设备或者终端，第三节点可以为中继设备或者终端。比如，如果第一节点为网络设备或者中继设备，第二节点为第一节点的下一跳中继设备，第三节点为第二节点的同一级中继设备，或者，第三节点为第二节点的下一跳中继设备或者接入第二节点的终端。
需进一步说明的是，这里描述的同级节点可以为无直接通信的两个节点，或者两个独立的节点同时链接到一个上级节点，或者链接到同一个下级节点等。例如，如果第一节点为网络设备101，第二节点可以为第一中继设备103，第三节点也可以为第二中继设备103(该第二中继设备103可以为第一中继设备103的下一级节点或者同级节点)或者是终端105。或者，如果第一节点为第一中继设备103，第二节点也可以为第二中继设备103(该第二中继设备103可以为第一中继设备103的下一级节点或者同级节点)，第三节点为第三中继设备103(该第三中继设备103可以为第二中继设备103的下一级节点或者同级节点)或者是终端105。
本申请实施例应用于无线通信系统，该无线通信系统包括第一节点，第二节点和第三节点。其中第一节点是第二节点和第三节点的上一级节点，第二节点可以是第三节点地上一级节点，或者第二节点和第三节点为同一级节点。
本申请实施例中，在需要第一节点进行资源配置的时候，第二节点向第一节点发送 其可用资源等信息，第一节点向第二节点配置回传资源，并且，在随后的调度过程中，第一节点可以向第二节点发送调度信息，用于指示实际调度的回传资源，第二节点可以在实际调度的回传资源上接收第一节点发送的信号。
回传链路：第二节点与第一节点进行通信的链路被称为回传链路。
接入链路：第二节点与第三节点进行通信的链路被称为接入链路。
下行控制区域：物理下行控制信道(physical downlink control channel，PDCCH)所占用的时频位置，在LTE中，PDCCH始终位于一个子帧的前m个(m可能的取值为1、2、3和4)符号。应注意，LTE中E-PDCCH和R-PDCCH的位置未处于前m个符号。
在NR中，下行控制区域可以由RRC信令通过控制资源集合(control resource set，CORESET)和搜索空间集合(search space set)灵活配置：
控制资源集合可配置PDCCH或控制信道单元(control channel element，CCE)的频域位置，时域的持续符号数(最大值为3)等信息；
搜索空间集合可配置PDCCH的检测周期以及偏移量，在一个时隙内的起始符号等信息。
例如，搜索空间集合可配置PDCCH周期为1个时隙，而时域起始符号为符号0，则终端或者中继节点需要在每个时隙的起始位置检测PDCCH。
下行数据区域：物理下行共享信道(physical downlink share channel，PDSCH)及其余下行信号所占用的时频位置，其中，其余下行信号可以包括如下至少一种信号：信道状态信息参考信号(channel state information-reference signal，CSI-RS)，同步信号/广播信道块(SS/PBCH block)等。
回传资源提前调度
以下行为例，回传链路的传输可分为两级确定：
(1)第一级：第一节点为第二节点配置回传资源集合，此配置可以通过高层信令(如RRC信令)完成。在一种可能的实现方式中，第一节点为第二节点配置接入资源集合，而第二节点通过接入资源集合推断出回传资源集合。
(2)第二级：第一节点为第二节点配置实际的回传链路传输，此配置可通过RRC等高层信令完成，也可以通过更底层的信令完成(例如，媒体接入控制层控制元素(MAC CE)或者DCI)。例如，周期性CSI-RS信号一般通过RRC信令配置，半持续CSI-RS信号可通过MAC CE激活，而PDSCH及非周期CSI-RS则一般通过DCI调度或触发。
以回传链路的PDSCH传输为例，上级节点通过DCI确定回传链路的PDSCH传输参数，例如时域资源位置，传输带宽，调制编码方式(modulation and coding scheme，MCS)，传输流数等，其中时域资源位置应处于上述回传资源集合内。回传链路需要承载的数据量是动态变化的，当数据量较小时，部分被高层信令配置的回传资源可能不会进行PDSCH传输。在LTE中继系统中，回传链路的PDSCH和对应的PDCCH位于同一子帧，当一个回传链路子帧未被调度或中继节点未检测到对应的PDCCH时，此子帧被浪费。
为了避免过多的资源浪费，中继节点可对未调度回传资源进行回收，具体地，当中继节点发现回传资源未被调度时，可利用其进行接入链路传输。此时，回传资源也可被用作接入链路，因此本申请也称其为可选回传资源。
为使得中继节点实现回传资源的回收，第一节点可以提前配置可选的回传资源对应的PDCCH，若该第二节点检测到调度DCI，则在对应的可选回传资源上接收信号；或该 第二节点未检测到调度DCI，则转而发送接入链路信号。通过提前调度，中继节点可实现对未调度可选回传资源的回收利用。为了确保能实现提前调度，PDCCH的提前量应足够中继节点进行DCI解码和接入链路信号生成等操作，因此提前量应满足一个最低门限K 1，其中，K 1可能由协议定义，也可能由中继节点上报。
图4示出了回传资源提前调度的示意图，中继节点会在回传链路中第k个时隙接收PDCCH，若该中继节点检测到调度DCI，则在第k+K 1个时隙接收上级节点发送的PDSCH，若在第k个时隙没有检测到DCI，则在第k+K 1个时隙向下级节点发送PDSCH。
当中继节点支持回传接入链路空分或频分复用时，即中继节点同时接收下行回传链路和上行接入链路，或中继节点同时发送上行回传链路和下行接入链路时，也可采用提前调度。以中继节点同时接收下行回传链路和上行接入链路为例，中继节点在第k个时隙检测到下行调度DCI后，可根据DCI内容调度下属终端设备，令其发送上行接入链路与所调度下行回传链路组成空分复用(space division multiplexing，SDM)，中继节点在第k+K 1个时隙同时接收下行回传链路和上行接入链路，在这种情况下，K 1个时隙的持续时间需要中继节点解析回传链路DCI，并发送接入链路DCI，同时还需要下属终端设备解析接入链路DCI，并准备接入链路上行发送内容。
应理解，本申请实施例中，一个时隙可包含控制区域和数据区域，如图4所示，该时隙k的前面若干符号(斜线区域)为其控制区域，该时隙k的后面若干符号(空白区域)为其数据区域。在回传链路上，中继节点在控制区域接收或检测上级节点发送的PDCCH，而在数据区域接收上级节点发送的PDSCH和/或其余信号(例如CSI-RS)；在接入链路上，中继节点在控制区域向下级节点发送PDCCH，而在数据区域向下级节点发送PDSCH和/或其余信号(例如CSI-RS)。
还应理解，该时隙中的控制区域和数据区域的位置仅仅是示意性的，假设回传资源的控制区域位于时隙的头部，且假设部分回传资源的头部也具有接入链路的控制区域，上述两个假设仅是一种可能的实现方式，本申请不排除其余的实现方式，例如回传资源的控制区域可能不位于时隙起始位置，而被调度回传时隙可能不发送接入链路PDCCH。
还应理解，本申请实施例中的回传资源可以为一个时间单元，该时间单元可以为一个时隙，也可以为多个时隙，还可以为多个符号等，本申请对此并不作任何限定。此外，上级节点在配置回传资源时还可能指示频域信息，例如指示回传资源的部分带宽(bandwidth part，BWP)信息等。本申请对回传资源的频域信息不做任何限定。
波束指示的提前调度
在NR中，DCI调度PDSCH时的波束指示也会用到提前调度。这里考虑终端或者中继节点的PDSCH接收，本申请假设中继节点也采用与终端相同或类似机制动态指示波束。如图5所示，中继节点(或者，终端)检测到PDSCH的调度DCI，其中会指示调度时延n，当调度时延大于预设门限K 2(NR中的参数Threshold-Sched-Offset)时，中继节点(或者，终端)采用DCI中的传输配置指示(transmission configuration indicator，TCI)指示确定接收波束；而当调度时延n小于预设门限K 2时，中继节点(或者，终端)采用一个默认的接收波束。
应理解，本申请实施例中回传资源的提前调度与波束指示的提前调度存在着区别。回传资源的提前调度是为了令中继节点(或者，终端)回收未被占用回传资源，中继节点知道当前DCI会采用提前调度指示一个满足最小门限的后续时隙，而当前时隙(图4 中时隙k)的用途(接入链路或回传链路)已经被(上级节点或中继节点)提前确定，不会造成资源浪费；波束指示的提前调度是为了令终端或中继有充足的时间检测DCI及切换模拟波束，终端或中继节点并不知道当前DCI是否会采用提前调度，而是根据DCI解析的结果确定是否提前调度，因此中继节点仍然需要对当前时隙(图5中时隙k)进行接收。
当调度提前量n≥K 3＝max(K 1，K 2)时，提前调度可以带来两个好处：
(1)中继节点可回收利用未被调度的可选回传资源；
(2)上级节点可以通过DCI中的TCI为下级节点指示波束。
为了提高动态回传资源配置的灵活性，可选回传资源的数目不应过少，然而一个可选回传时隙一般需对应一次PDCCH的接收，若在一个周期内配置了m个可选回传时隙，则中继节点(或者，终端)需要进行m次PDCCH的接收与检测，而过多的PDCCH接收将增加中继节点的回传链路开销(包括回传与接入链路切换的保护间隔)，并且中继节点接收过多的PDCCH也不利于其在接入链路的PDCCH发送；另一方面，过少的可选资源配置则会影响系统吞吐量和灵活度。
本申请实施例提出了一种资源调度的方法，在回传资源的分配与调度过程中可以保证动态回传资源的分配(即中继节点或者终端可以回收利用未被调度的回传资源)，同时避免了中继节点或者终端过多的PDCCH接收。
图6示出了根据本申请实施例的资源调度的方法400的示意性流程图，如图6所示，该方法400包括：
S410，第一节点向第二节点发送资源配置信息，该第二节点接收该第一节点发送的资源配置信息，该资源配置信息用于指示回传资源集合的时域位置，该回传资源集合包括一个固定回传资源和多个动态回传资源；
S420，在该固定回传资源，该第一节点向该第二节点发送第一指示信息，该第二节点接收该第一节点发送的该第一指示信息，该第一指示信息用于指示该多个动态回传资源中被调度的动态回传资源的信息；
S430，该第一节点在该被调度的动态回传资源上向该第二节点发送信号，该第二节点在该被调度的动态回传资源上接收该第一节点发送的信号。
具体而言，该第一节点向该第二节点发送资源配置信息，该资源配置信息指示了回传资源集合的时域位置，该回传资源集合包括一个固定回传资源和多个动态回传资源，在配置了回传资源集合后，该第一节点可以在该回传资源集合的固定回传资源上发送第一指示信息，该第一指示信息指示了该多个动态回传资源集合中被调度的动态回传资源集合的信息，该第二节点收到该信息后可以确定该第一节点将要在该被调度的动态回传资源上发送信号，该第二节点在该被调度的动态回传资源上接收该第一节点发送的信号。
可选地，该第一节点为网络设备，中继节点或者具有中继节点功能的终端。
可选地，该第二节点为中继节点或者具有中继节点功能的终端。
应理解，本申请实施例中的固定回传资源是第二节点接收该第一指示信息的时频资源。
还应理解，本申请实施例中的动态回传资源可以理解为可以被调度的回传资源，即该第一节点虽然为该第二节点配置了该多个动态回传资源，但是在实际调度过程中，该第二节点需要根据该第一指示信息来确定该多个动态回传资源中的哪些回传资源作为实 际被调度的回传资源。
还应理解，本申请实施例中，资源配置信息可以由该第一节点生成并发送给该第二节点，该资源配置信息还可以由控制节点生成并发送给该第一节点，并通过该第一节点发送给该第二节点，该控制节点为与该第一节点不同的网络设备或者中继节点。
本申请实施例中，该第一节点向该第二节点配置该回传资源集合包括但不限于以下两种方式。
方式一：单独配置
该第一节点可以为该第二节点配置多个回传资源，该多个回传资源中包括一个固定回传资源和多个动态回传资源，同时，该第一节点还为该第二节点配置了该固定回传资源和该多个动态回传资源的对应关系。
应理解，回传资源的配置粒度可以是一个时间单元，例如，可以是一个时隙，也可以是多个时隙，还可以是多个符号，本申请实施例中主要以时隙的配置粒度加以说明，但并不排除其余配置粒度，本申请实施例中的“回传资源”也可以称之为“回传时隙”，或者“回传资源时隙”。在配置回传资源时间单元时，需同时指示此时间单元所采用的参数集，例如，子载波间隔、循环前缀(cyclic prefix，CP)类型或长度、DMRS类型等。其中，部分参数可通过BWP配置得到。如前所述，固定回传资源是发送第一指示信息的资源，而第一指示信息一般由PDCCH发送，在NR中，PDCCH所占用时间资源一般为若干个时域符号(例如，1至3个符号)，而不是整个时隙，因此，本申请中，固定回传时隙表示包含固定回传资源的时隙，而不是指整个时隙为固定回传资源。
一种具体的实施方式是，第一节点为第二节点分配多个回传资源时隙，其中包含至少一个固定回传资源时隙，而每个动态回传时隙均与一个固定回传时隙相关联，此关联关系表示该动态回传时隙对应的第一指示信息在该固定回传时隙上发送。
另一种具体的实施方式是，第一节点为第二节点分配多个回传资源时隙，每个回传资源时隙均关联一个回传资源时隙，表示该回传资源时隙的第一指示信息在所关联回传资源时隙上发送。当一个回传时隙所关联回传时隙是自身时，此回传时隙为前述固定回传时隙。
在上述两种实施方式中，回传时隙的关联关系可以在配置回传时隙的同时配置，也可以由单独的信令配置。在配置完所述关联关系后，第一节点还应向第二节点配置包含第一指示信息的PDCCH所处位置，该PDCCH应处于固定回传时隙，当存在多个固定回传时隙时，每个固定回传时隙均可能配置PDCCH。在NR中，PDCCH所占用时频位置由CORESET和search space set的配置得到。
此外，还有如下一种实施方式，第一节点为第二节点分配多个回传资源时隙，并通过配置PDCCH位置隐式的指示固定回传时隙所处位置。具体地，第一节点在为第二节点配置的PDCCH时频位置即为固定回传时隙位置，而第二节点可配置PDCCH所包含的第一指示信息所指示的多个回传时隙。所配置PDCCH可位于所配置的一个回传资源时隙上，也可以位于一个独立的时隙。同样的，第一节点可配置多个PDCCH，指示多个固定回传时隙。
应注意，上述回传时隙均为周期性配置，多个关联的回传时隙一般应具有相同的周期。回传时隙的周期可以单独配置，也可以直接采用其余配置的周期，例如，回传时隙的周期可以与第一节点所采用的TDD上下行公共配置(协议中参数 tdd-UL-DL-ConfigurationCommon)周期一致。在一些情况下，第一节点可以配置两套TDD上下行公共配置，两套配置的周期相同，然而具体的上下行时隙配置可不同，这时回传资源也可采用类似的两套配置。PDCCH也需要由search space set配置周期，一般情况下，search space set所配置周期应该与固定回传资源周期一致，或者，search space set所配置周期应该为固定回传资源周期的整数倍。
方式二：回传资源组配置
该第一节点可以为该第二节点配置一个回传资源组，该回传资源组的配置为：
{
回传资源组编号；
回传资源组周期；
第一时间单元(固定回传资源)在回传资源周期内的时域位置；
第二时间单元(动态回传资源)在回传资源周期内的时域位置；
第三时间单元(动态回传资源)在回传资源周期内的时域位置；
…
第N时间单元(动态回传资源)在回传资源周期内的时域位置；
}
应理解，上述配置内容表示第一节点可向第二节点配置多个回传资源组，用于避免一个固定回传资源指示过多的动态回传资源，同时提升配置的灵活性。
还应理解，回传资源的配置粒度可以是一个时间单元，例如，可以是一个时隙，也可以是多个时隙，还可以是多个符号，本申请实施例中主要以时隙的配置粒度加以说明，但并不排除其余配置粒度。此外，上述资源组的配置中仅具有一个固定回传资源，但本申请并不排除回传资源组中具有多个固定回传时隙的情况。在配置回传资源时间单元时，需同时指示此时间单元所采用的参数集，例如，子载波间隔、CP类型或长度、DMRS类型等。其中，部分参数可通过BWP配置得到。如前所述，固定回传资源是发送第一指示信息的资源，而第一指示信息一般由PDCCH发送，在NR中，PDCCH所占用时间资源一般为若干个时域符号(例如，1至3个符号)，而不是整个时隙，因此，本申请中，固定回传时隙表示包含固定回传资源的时隙，而不是指整个时隙为固定回传资源。
在一种可能的实现中，第一节点在为第二节点配置回传资源时还可配置回传资源的频域信息，首先，第一节点在为第二节点配置回传资源的时候可能配置BWP信息，其中包括带宽信息。其次，第一节点可以为第二节点直接配置回传资源的频域信息，例如频域位置与范围，频域信息的配置粒度一般为整数倍资源块(resource block，RB)。当回传资源被配置了频域位置与范围，则表示第一节点调度的回传链路不会超过此范围，而第二节点可在范围外调度接入链路。
应注意，方式二中的固定回传时隙可能不会被直接配置，而可由包含第一指示信息的PDCCH配置得到，具体方法同上，在此不赘述；此外，固定回传时隙也可以是一个回传资源组的第一个时隙。
在配置方式二中，回传时隙被分组配置，同组的动态回传时隙由一个固定回传时隙上的第一指示信息指示，因此不需要额外的信令配置回传时隙间的关联关系。在配置完回传资源组后，第一节点还应向第二节点配置包含第一指示信息的PDCCH所处位置，该PDCCH应处于固定回传时隙，当存在多个回传时隙组时，每个回传时隙组的固定回 传时隙均可能配置PDCCH。在NR中，PDCCH所占用时频位置由CORESET和search space set的配置得到。
图7示出了一种回传资源提前调度的示意图，如图7所示，第一节点为该第二节点配置了一个固定回传时隙(时隙0)和多个动态回传时隙(时隙2、5和8)。
具体而言，该固定回传资源可以是时隙0的控制区域，多个动态回传资源可以是时隙2、5和8的数据区域。该第二节点可以在时隙0的控制区域接收该第一节点发送的第一指示信息，该第一指示信息指示了时隙2、5和8的数据区域均为被调度的回传资源，或者，该第一指示信息指示了时隙2、5和8的数据区域均不是被调度的回传资源，或者，该第一指示信息指示了该时隙2、5和8的数据区域中的至少部分为被调度的回传资源。
例如，该第一指示信息指示了时隙2的数据区域为被调度的回传资源，而时隙5和8的数据区域不被调度，则该第二节点可以调度该时隙2的数据区域接收该第一节点发送的PDSCH，还可以将不被调度的时隙5和8的数据区域用于接入链路资源(或者其他用途)。
应理解，为了使得该第二节点可以回收利用未被调度的动态回传资源，固定回传资源和被调度的动态回传资源(图7中时隙0和时隙2)之间的间隔应该大于上文中的门限值K 1，若该第一节点需要在被调度的动态回传资源处进行动态波束的指示(或者说动态指示空间QCL关系)，则固定回传资源与被调度的动态回传资源之间的间隔应该大于上文中的门限值K 2。
本申请实施例中，控制区域和数据区域并不是一一对应，而是一个控制区域对应多个数据区域，在后续的调度过程中，该第二节点可以在一个控制区域接收多个数据区域的调度DCI，或者，接收多个数据区域是否被调度的指示信息。
应理解，本申请实施例中，该第二节点的各种RRC配置(或者其他高层配置)可能由该第一节点配置并发送，也可能由另一个网络设备(例如，gNB，CU或DU)配置后通过该第一节点发送，本申请对此并不作任何限定。
本申请实施例的资源调度的方法，通过在一个回传资源处接收指示信息，该指示信息指示了多个回传资源中被调度的回传资源，助于在保证系统灵活度的同时避免终端或者中继节点的切换开销。
可选地，该第一指示信息包括该被调度的动态回传资源的下行调度参数，一般情况下，下行调度信息由DCI承载，例如NR中的DCI格式1_0与1_1。
具体而言，该第一指示信息包括该被调度的动态回传资源中每一个动态回传资源的下行调度参数，该第二节点接收该第一指示信息后，可以根据该每一个被调度动态回传资源的下行调度参数，在该每一个动态回传资源上接收信号。
应理解，该第二节点在每一个被调度的动态回传资源上接收信号可以是第一节点发送的信号，也可以是其他节点发送的信号，本申请对此并不作任何限定。
可选地，该第一指示信息为至少一个DCI，该至少一个DCI中的每个DCI对应被调度的动态回传资源中的一个被调度的动态回传资源。
可选地，该方法400还包括：
在该固定回传资源，该第一节点向该第二节点发送第二被调度的动态回传资源的下行调度参数，该第二节点接收该第一节点发送的该第二被调度的动态回传资源的下行调度参数，该被调度的动态回传资源包括该第二被调度的动态回传资源。
可选地，该固定回传资源和该第二被调度的动态回传资源位于同一个时间单元，或者，该固定回传资源和该第二被调度的动态回传资源位于相邻的时间单元。
具体而言，由于在实际调度过程中，系统很少出现一个周期内完全没有回传数据的情况，因此，为了进一步减少切换开销，可以在固定回传资源接收该第一节点发送的第二被调度的动态回传资源的下行调度参数，该第二被调度的动态回传资源与该固定回传资源位于同一个时间单元，或者，该第二被调度的动态回传资源与该固定回传资源位于相邻的时间单元。
下面以该第二被调度的动态回传资源与该固定回传资源位于同一个时隙为例进行说明。
应理解，由于固定回传资源和该第二被调度的动态回传资源的间隔为0，因此即使第二节点未收到第二被调度的动态回传资源的下行调度参数，第二节点也可能无法回收利用第二被调度的动态资源。
在一种可能的实现中，第一节点为第二节点配置的周期或半持续(semi-persistent)信号应位于固定回传资源或第二被调度的动态回传资源，所述周期信号包含CSI-RS，SS/PBCH块，TRS等。
在另一种可能的实现中，当第一节点所配置的周期信号位于固定回传资源或第二被调度的动态回传资源之外时，第二节点忽略此配置，或第二节点可不接收位于固定回传资源或第二被调度的动态回传资源之外的所配置信号。一个具体的例子如下，将第二节点由初始接入至正常工作的流程分为两个阶段。
第一阶段：第二节点首先以单独的终端功能接入第一节点，第一节点可为第二节点配置CSI-RS等周期信号，而后第一节点为第二节点配置回传资源等中继节点特有配置。
第二阶段：第二节点开启其网络设备功能为下级节点服务。
在第二阶段开始后，第一节点在第一阶段所配置周期信号若位于固定回传资源或第二被调度的动态回传资源之外，则第二节点忽略此配置，或第二节点可不接收位于固定回传资源或第二被调度的动态回传资源之外的所配置信号。或者，在第二阶段开始后，第二节点忽略所有在第一阶段所配置信号。
图8示出了另一种提前调度的示意图，如图8所示，该第一节点为该第二节点配置了固定回传资源(时隙2的控制区域)以及三个动态回传资源(时隙2、5和8的数据区域)，该第二节点在时隙2的控制区域接收的PDCCH指示了时隙2、5和8的数据区域的下行调度信息，或者，该第二节点在时隙2的控制区域接收了时隙2、5和8的数据区域的DCI(例如，调度PDSCH的DCI)，在该时隙2的控制区域接收的DCI指示了时隙2的下行调度参数，在该时隙2的控制区域接收的DCI指示了时隙5的下行调度参数，在该时隙2的控制区域接收的DCI指示了时隙8的下行调度参数。
在本例中，时隙2的数据区域即为上述第二被调度的动态回传资源。
应理解，图8中每个动态回传资源均由固定回传时隙的DCI调度，图8仅仅是示意性的，并不代表DCI的实际时频域位置。
还应理解，在该时隙2的控制区域接收的DCI还可以携带字段指示时隙5的数据区域的接收波束的信息，在该时隙2的控制区域接收的DCI还可以携带字段指示时隙8的数据区域的接收波束的信息，而时隙2的数据区域的接收波束可以采用默认的接收波束或一个提前配置的接收波束。
可选地，该方法还包括：
在该固定回传资源，该第二节点接收该第一节点发送的第三被调度的动态回传资源的接收波束的信息，该被调度的动态回传资源包括该第三被调度的动态回传资源。
可选地，若该被调度的动态回传资源中包括第二被调度的动态回传资源，该第二被调度的动态回传资源为与该固定回传资源位于同一个时间单元或者相邻时间单元的动态回传资源，则该第一指示信息还包括用于指示第三被调度的动态回传资源的接收波束的信息，该第三被调度的动态回传资源为该被调度的动态回传资源中除该第二被调度的动态回传资源以外的动态回传资源中的至少部分。
可选地，若该被调度的动态回传资源中没有与该固定回传资源位于同一个时间单元或者相邻时间单元的动态回传资源，则该第一指示信息还包括用于指示第三被调度的动态回传资源的接收波束的信息，该第三被调度的动态回传资源为该被调度的动态回传资源中的至少部分。
如图8所示，该固定回传资源(时隙2的控制区域)和第二被调度的动态回传资源(时隙2的数据区域)位于同一个时隙，则该第一指示信息还包括第三被调度的动态回传资源(时隙5的数据区域和时隙8的数据区域)的接收波束的信息。
具体地，时隙2的控制区域接收的时隙5和时隙8的DCI分别携带字段指示时隙5和时隙8的接收波束的信息。
可选地，当第一指示信息为至少一个DCI时，可以在该至少一个DCI中部分或全部DCI中携带字段指示第三动态回传资源的PDSCH所采用的接收波束。
例如，如图7所示，该第一节点在时隙0接收时隙2的DCI，该DCI中携带的TCI用来指示时隙2的PDSCH所采用的接收波束，一般来说，PDSCH的接收波束由空间QCL关系来指示。而空间QCL关系使用传输配置指示来指示，现有协议中，TCI包含3比特，即可以指示8个TCI状态，每个状态关联了至少一个参考信号，用于指示QCL关系。更具体的，一个TCI状态可包含一个配置了Type-D QCL的参考信号用来指示后续PDSCH的接收波束，该参考信号与后续PDSCH的DMRS具有Type-D QCL关系，即中继节点可以用接收此参考信号的波束来接收后续的PDSCH。其中，Type-D QCL是关于空间接收参数(spatial Rx parameter)的QCL。
应理解，目前协议中的TCI仅可指示一个接收波束，即一个TCI状态仅包含一个参考信号用于指示Type-D QCL关系，不排除后续协议支持一个TCI指示多个接收波束的可能性，本申请不对一个TCI状态所指示的接收波束数目加以限定。
又例如，该第一节点在时隙0接收时隙5和8的DCI，其中分别携带TCI来指示时隙5和8的PDSCH所采用的接收波束。
本申请实施例中，该第一节点可以通过控制资源集合(CORESET)和搜索空间集合(search space set)的配置确定固定回传资源的控制信道PDCCH。其中，PDCCH的频域子载波资源，时域符号数目，DMRS配置，交织方案，预编码方案，QCL关系等由CORESET确定，在被配置了CORESET后，中继节点即可得到若干控制信道单元(control channel element，CCE)；一个搜索空间集合需要和一个CORESET关联，搜索空间集合指示了终端或中继节点检测PDCCH的周期，周期内的偏移量，CORESET起始符号的时域位置，需要检测的聚合级别及每个聚合级别内的候选PDCCH(PDCCH candidate)数目，每个候选PDCCH所占用的CCE索引，需要检测的DCI格式等信息。其中，聚合级别表示一 个候选PDCCH所占用的CCE数目，可能的取值有1、2、4、8、16等。
在本申请实施例中，该被调度的动态回传资源的PDSCH调度信息均可以在固定回传资源的PDCCH中发送，该被调度的动态回传资源中的第二被调度动态回传资源(时隙2的数据区域)和固定回传资源(时隙2的控制区域)可以位于同一个时间单元(时隙2)，也可以位于相邻的时间单元。
可选地，该被调度的动态回传资源中每一个被调度的动态回传资源对应一个控制资源集合，或者，该被调度的动态回传资源中每一个被调度的动态回传资源对应一个搜索空间集合或者搜索空间集合的子集。
可选地，该方法还包括：
该第一节点通过该每一个被调度的动态回传资源和控制资源集合的对应关系，确定每一个动态回传资源的DCI的发送方式；或者，
该第一节点通过该每一个被调度的动态回传资源和搜索空间集合的对应关系，确定每一个动态回传资源的DCI的发送方式；或者，
该第一节点通过该每一个被调度的动态回传资源和搜索空间集合的子集的对应关系，确定每一个动态回传资源的DCI的发送方式。
可选地，该DCI的发送方式包括对应PDCCH的时频资源映射信息等。
具体而言，该每一个被调度的动态回传资源与控制资源集合或搜索空间集合的对应关系包括但不限于以下几种方式：
方式一
多个CORESET配置，且CORESET与动态回传资源绑定。不同的回传资源采用不同CORESET中的DCI调度，该第一节点可提前通过RRC信令绑定CORESET与动态回传资源(例如，绑定CORESET索引p与回传资源索引)。同时，该第二节点也可根据DCI中已有的时域资源指示字段确定DCI所对应的动态回传资源。
方式二
search space set与回传资源绑定。不同的回传资源采用不同search space set中的DCI调度，该第一节点可提前通过RRC信令绑定search space set与动态回传资源(绑定search space set索引s与回传资源索引)。同时，该第二节点也可根据DCI中已有的时域资源指示字段确定DCI所对应的动态回传资源；
方式三
search space set所配置的候选PDCCH的与回传资源绑定。不同的回传资源在search space set中利用不同的候选PDCCH进行调度DCI盲检。同时，该第二节点也可根据DCI中已有的时域资源指示字段确定DCI所对应的动态回传资源。
具体地，第一节点通过搜索空间集合的配置为第二节点指示PDCCH盲检周期及在一个周期内的候选PDCCH数目，或者第二节点需要在一个搜索空间集合周期内盲检测的候选PDCCH数目，每个候选PDCCH均包含L个CCE，而这L个CCE的索引号由协议约定规则通过多个参数(例如第二节点的RNTI标识、CORESET内CCE总数、候选PDCCH总数等)计算得到，其中，L表示聚合级别，一个搜索空间集合可配置多个聚合级别。
本申请实施例中可考虑在候选PDCCH的CCE索引规则中引入回传资源的标识作为一个新的参数，使得不同的回传资源对应于不同的候选PDCCH，具体的，一个回传资源 对应于若干候选PDCCH中的一部分。
本申请实施例中也将所述若干候选PDCCH的一部分称为搜索空间集合的子集。在一些情况下，不同的候选PDCCH具有不同的CCE索引，而在另外一些情况下，不同候选PDCCH的CCE索引可能发生碰撞，例如，调度时隙2和时隙5的一个或多个候选PDCCH具有相同的CCE索引，此时，第二节点无法通过PDCCH的CCE索引确定所调度回传资源，因此需要通过DCI中的字段进行进一步的确认。
应理解，本申请实施例中，该搜索空间集合的子集包括该每一个被调度的动态回传资源的一个或者多个候选PDCCH的CCE索引。
在本实施例中，每个调度DCI中均可包含一个指示信息，指示了所述回传资源组中被调度的回传资源的总数，例如，在上述例子中，当时隙2和5被调度时，指示信息指示被调度的回传资源数目为2，上述指示信息在一些情况下可减少DCI盲检次数，也可保证HARQ反馈不会出现错误。
上述实施例中，回传资源组中被调度的动态回传资源的调度DCI均位于固定回传时隙，这样的设计易于实现，但是需要该第二节点在固定回传资源进行大量的DCI盲检测，有可能会增加该第二节点的复杂度，并且，过于提前的调度参数配置有可能不利于调度的灵活性，以下提出了一种改进的资源调度的方法500。
图9示出了根据本申请实施例的资源调度的方法500的示意性流程图，如图9所示，该方法500包括：
S510，第一节点向第二节点发送资源配置信息，该第二节点接收该第一节点发送的资源配置信息，该资源配置信息用于指示回传资源集合的时域位置，该回传资源集合包括一个固定回传资源和多个动态回传资源；
S520，在该固定回传资源，该第一节点向该第二节点发送第一指示信息，该第二节点接收该第一节点发送的该第一指示信息，该第一指示信息用于指示该多个动态回传资源中被调度的动态回传资源；
S530，在第一被调度的动态回传资源上，接收该第一节点发送的第一下行控制信息DCI，该第一DCI用于指示该第一被调度的动态回传资源的下行调度参数，该被调度的动态回传资源包括该第一被调度的动态回传资源；
S540，该第一节点在该第一被调度的动态回传资源上向该第二节点发送信号，该第二节点在该第一被调度的动态回传资源上接收该第一节点发送的信号。
具体而言，在固定回传资源，该第二节点接收的第一指示信息只用于指示该多个动态回传资源是否被实际调度，而实际的PDSCH调度DCI则在对应的动态回传时隙中被发送。
应理解，该第一被调度的动态回传资源表示PDCCH与PDSCH复用在同一时间单元的动态回传资源，并且第二节点通过第一指示信息确定是否检测第一被调度的动态资源的PDCCH。
例如，图10示出了一种提前调度回传资源的示意图，该第一节点为该第二节点配置了固定回传资源(时隙0的控制区域)和动态回传资源(时隙2、5和8的数据区域)，该第二节点在时隙0的控制区域接收该第一指示信息，该第一指示信息指示时隙2、5和8的数据区域是否被实际调度，若该第一指示信息指示时隙2、5和8的数据区域均为将被调度的回传资源，则该第二节点在时隙2的控制区域接收时隙2的PDSCH的调度DCI， 在时隙5的控制区域接收时隙5的PDSCH的调度DCI，在时隙8的控制区域接收时隙8的PDSCH的调度DCI。
可选地，第一指示信息可采用bitmap的方式指示后续回传资源是否被调度，例如，当时隙2、5和8为动态回传时隙时，第一指示信息采用三个比特来指示后续哪些时隙会被调度，例如[1 0 0]表示仅时隙2被调度，[1 1 0]表示时隙2和5被调度，以此类推。
可选地，该方法500还包括：
在该固定回传资源，该第一节点向该第二节点发送第三被调度的动态回传资源的接收波束的信息，该被调度的动态回传资源包括该第三被调度的动态回传资源。
可选地，若该被调度的动态回传资源中没有与该固定回传资源位于同一个时间单元或者相邻时间单元的动态回传资源，则该第一指示信息还包括用于指示第三被调度的动态回传资源的接收波束的信息，该第三被调度的动态回传资源为该被调度的动态回传资源中的至少部分。
例如，可以在该第一指示信息中携带TCI指示该被调度的动态回传资源中至少部分动态回传资源的接收波束，若该第一指示信息指示了时隙2、5和8的数据区域均为将被调度的回传资源，则可以在该第一指示信息中增加9个比特的TCI字段来指示时隙2、5和8的接收波束的信息，还可以在该第一指示信息中增加6个比特的TCI字段来指示时隙5和8的接收波束的信息。
在一些可能的实现方式中，该第一指示信息既可以指示该多个动态回传资源中被调度的动态回传资源，还可以指示被调度的动态回传资源中至少部分动态回传资源的接收波束的信息。
可选地，该第一指示信息还包括第二被调度的动态回传资源的下行调度参数该被调度的动态回传资源包括该第二被调度的动态回传资源。
可选地，该固定回传资源和该第二被调度的动态回传资源位于同一个时间单元，或者，该固定回传资源和该第二被调度的动态回传资源位于相邻的时间单元。
具体而言，为了更高效的利用固定回传资源，该第一指示信息还可以包括该第二被调度的动态回传资源的PDSCH调度DCI。或者，还可以表述为，在固定回传资源的控制区域上发送一个被调度的动态回传资源的PDSCH的调度DCI，并且在此DCI中添加字段(或重用已有字段)指示其余动态回传资源是否被调度。在这种情况下，固定回传资源的DCI与所调度PDSCH所占用资源一般是连续的，或者，占用同一个时间单元。
可选地，还可以在该DCI中添加字段指示第三被调度的动态回传资源的接收波束的信息。
应理解，若该被调度的动态回传资源中包括第二被调度的动态回传资源，该第二被调度的动态回传资源为与该固定回传资源位于同一个时间单元或者相邻时间单元的动态回传资源，则该第一指示信息还包括用于指示第三被调度的动态回传资源的接收波束的信息，该第三被调度的动态回传资源为该被调度的动态回传资源中除该第二被调度的动态回传资源以外的动态回传资源中的至少部分。
下面以固定回传资源和该第二被调度的动态回传资源占用同一个时间单元为例进行说明。
图11示出了再一种提前调度回传资源的示意图，如图11所示，该第一节点为该第二节点配置了一个固定回传资源(时隙2的控制区域)和多个动态回传资源(时隙2、5 和8的数据区域)，该第二节点在时隙2的控制区域接收的调度DCI调度了时隙2的PDSCH，且指示了动态回传资源5和8是否被调度，或者说，是否需要中继节点检测调度DCI。
进一步可选地，固定回传资源的DCI还可以指示被调度的动态回传资源中的至少部分动态回传资源的接收波束的信息(或空间QCL关系)。
应理解，该时隙2的控制区域接收的调度DCI可以指示时隙5和8的接收波束的信息，而时隙2的接收波束可以为默认的接收波束或一个提前配置的接收波束。
为降低复杂度，图11所示的动态回传时隙(时隙5和8)的PDCCH与PDSCH可以具有相同的QCL关系，或者，该第二节点可用同样的接收波束接收同一个被调度的动态回传时隙的PDCCH和PDSCH。
下面对图11中提前调度回传资源的过程进行详细描述。
(1)回传资源集合的配置
具体而言，该回传资源集合的配置与方法400中的相同，为了简洁，在此不再赘述。
(2)该第一节点为该第二节点配置至少一个CORESET，用于传输固定回传时隙的调度DCI。
具体而言，为了和下文在动态回传资源配置的CORESET进行区别，在固定回传资源配置的CORESET记为CORESET p1，CORESET p1与现有协议的CORESET一致。
(3)该第一节点为该第二节点配置search space set。
具体而言，search space set关联的CORESET为上述CORESET p1，并且配置search space set的周期与移位，使得该第二节点始终在固定回传资源监测DCI。一种简单的search space set配置方法是配置一个search space set s1，search space set s1的(时隙级)的周期与偏移和固定回传资源一致。search space set s1的符号位置可以位于时隙的头部，也可以位于其他位置。应理解，该第一节点还可以通过其余的CORESET与search space set配置方式使得该第二节点总是在固定回传资源接收PDCCH或监测DCI。
上述DCI用于指示第二被调度的动态回传资源(例如，图11中时隙2的数据区域)的PDSCH的下行调度参数，并且携带字段指示后续多个回传资源(例如，图11中的时隙5和8)是否会被调度，例如，考虑如图11所示情况，时隙2处的DCI可以通过两个比特指示时隙5和时隙8是否会被调度，例如[1 1]指示两时隙均被调度，[1 0]表示时隙5被调度，而时隙8未被调度等。
上述DCI还可以携带字段指示后续多个被调度的动态回传资源(例如，图11中的时隙5和8)中的至少部分动态回传资源的PDSCH所采用波束(或空间QCL)关系，一般来说，PDSCH的空间QCL关系使用TCI来指示，现有协议中，TCI包含3比特，即可以指示8个TCI状态，每个状态关联了至少一个参考信号，用于指示QCL关系。更具体的，TCI采用配置了Type-D QCL的参考信号用来指示后续PDSCH的接收波束。若需要通过TCI指示后续多个回传时隙的波束，则需要对应数目的TCI字段，例如，需要指示两个被调度的动态回传时隙时，需要6比特的TCI字段。
应理解，若上述DCI需要指示N个动态回传资源是否被调度，需要N个比特，而若需要指示N个动态回传资源的TCI状态，则需要3N个比特，一共需要4N个比特。可以将两种指示合并以节省开销，例如，将TCI的一个状态用于指示对应的动态回传资源未被调度，例如，TCI的前七个状态配置为普通的QCL指示，而最后一个状态可用来 指示对应的动态回传资源未被调度。这样可节省N比特的DCI开销。当DCI所在CORESET未被配置PDSCH的TCI，或者当DCI不包含TCI字段时，该DCI仅用N个比特指示动态回传时隙是否存在。
在一种可能的实现中，为了避免过大的DCI长度，回传资源组中的动态回传资源数目有最大限制，例如，可定义一组回传资源最多包含三个动态回传资源，这样所增加的指示比特数目有限。或者，在一组回传资源中，仅包含一个固定动态回传资源及一个动态回传时隙，这样，该第一节点可利用现有的3比特TCI信息来指示该动态回传时隙，而不用增加额外的比特。
(4)在被调度的动态回传资源，该第一节点为该第二节点配置CORESET，用于传输被调度的动态回传资源的调度DCI。
上述在固定回传资源接收的DCI在指示了动态回传资源是否被调度(若指示了被调度，该DCI还可以指示被调度的回传资源的接收波束)，同时也暗示了动态PDSCH所对应的PDCCH是否存在及对应的波束(TCI)。可为被调度的动态回传时隙配置一个专用的CORESET，记为CORESET p2，CORESET p2与普通CORESET的区别是：与普通CORESET具有QCL关系的参考信号是由RRC信令配置的，而CORESET p2的QCL参考信号在RRC配置时可能处于缺省状态，或者是可修改的。在固定回传资源接收的DCI指示了对应PDSCH的TCI状态后，CORESET p2采用相同的TCI状态。或者，协议直接定义前述TCI指示的是CORESET p2和PDSCH的共用TCI。在协议中，可通过search space set的配置将CORESET p2配置至不同的被调度的动态回传资源，但如果动态回传资源未被指示，则该第二节点可以忽略此次检测。应理解，该第一节点还可以通过其余的CORESET与search space set配置方式使得该第二节点在被调度的动态回传资源上根据第一指示信息接收PDCCH或监测DCI。
在一种可能的实现方式中，固定回传资源接收的DCI仅指示了动态回传资源是否被调度，而未包含TCI指示，或者未包含接收波束指示，此时，CORESET p2可能被配置了QCL关系，而对应动态回传资源采用和CORESET p2相同的QCL关系，或相同的TCI状态，或相同的接收波束。
在一种可能的实现方式中，若后续的一个动态回传资源(例如，图11中的时隙5或8)被指示了与该第二动态回传资源(例如，图11中的时隙2)相同的接收波束(或者空间QCL关系)，可以重复利用该固定回传资源的调度DCI。具体地，一个固定回传时隙发送的DCI可调度多个动态回传时隙，具体被调度的动态回传时隙可由DCI中的字段指示。
本申请实施例的资源调度的方法，通过提前指示动态回传资源是否被调度，可以在保证系统灵活度的同时避免过多的切换开销，同时，每个动态回传资源的调度信息在每个动态回传资源中发送，有助于降低第二节点的复杂度和提高调度的灵活性。
图12示出了本申请实施例的资源调度的方法600的示意性流程图，如图12所示，该方法600包括：
S610，第一节点向第二节点发送资源配置信息，该第二节点接收该第一节点发送的资源配置信息，该资源配置信息用于指示回传资源集合的时域位置，该回传资源集合包括一个固定回传资源和多个动态回传资源；
S620，在该固定回传资源，该第一节点向该第二节点发送第二DCI，该第二节点接 收该第一节点发送的该第二DCI，该第二DCI用于指示第四被调度的动态回传资源的下行调度参数且该第二DCI用于指示第五被调度的动态回传资源被调度，该多个动态回传资源包括该第四被调度的动态回传资源和该第五被调度的动态回传资源；
S630，该第一节点在该第四被调度的动态回传资源和该第五被调度的动态回传资源上向该第二节点发送信号，该第二节点根据该第一DCI，在该第四被调度的动态回传资源和该第五被调度的动态回传资源上接收该第一节点发送的信号。
具体而言，方法600提供了一种逐级的动态回传资源指示，逐级的动态回传资源指示带来的好处是进一步节省了DCI的指示开销，使得每个DCI仅需要使用3个比特的TCI(或者1个比特的动态回传资源指示，或者1个比特的动态资源指示和3个比特的TCI)来指示后一个动态回传资源，这和普通DCI的TCI开销一致。
可选地，该固定回传资源和该第四被调度的动态回传资源位于同一个时间单元，或者，该固定回传资源和该第四被调度的动态回传资源位于相邻的时间单元。
可选地，该方法600还包括：
在该固定回传资源，接收该第一节点发送的该第五被调度的动态回传资源的接收波束的信息。
下面以固定回传资源和该第四被调度的动态回传资源位于同一个时间单元进行说明。
图13示出了再一种提前调度回传资源的示意图，如图13所示，该第一节点为该第二节点配置了一个固定回传资源(时隙2的控制区域)和多个动态回传资源(时隙2、5和8的数据区域)，该第二节点在时隙2的控制区域接收的第一DCI调度了时隙2的PDSCH，或者说，该第一DCI指示了时隙2的下行调度参数。
可选地，该第一DCI还携带1个比特指示时隙5被调度。
进一步可选地，该第一DCI还携带3个比特指示时隙5的接收波束的信息。
可选地，该方法600还包括：
在该第五被调度的动态回传资源，接收该第一节点发送的第三DCI，该第三DCI用于指示该第五被调度的动态回传资源的下行调度参数且该第三DCI用于指示第六被调度的动态回传资源被调度，该多个动态回传资源包括该第六被调度的动态回传资源。
可选地，该方法600还包括：
在该第五被调度的动态回传资源，接收该第一节点发送的该第六被调度的动态回传资源的接收波束的信息。
如图13所示，若该第一DCI指示了时隙5被调度，则该第二节点在时隙5接收该第一节点发送的第二DCI，该第二DCI指示了时隙5的下行调度参数。
可选地，该第二DCI还可以携带字段指示时隙8被调度。
进一步可选地，该第二DCI还携带字段指示了该时隙8的接收波束。
本申请实施例的资源调度的方法，通过逐级指示的方式提前调度回传资源，有助于在保证系统灵活度的同时避免过多的切换开销，同时，也可以节省DCI的指示开销。
上文结合方法400至方法600，详细得描述了下行回传资源的配置与指示，本申请实施例还可以将该方法推广至上行回传资源。同下行回传资源，该第一节点也不能任意的动态调度上行回传资源，以避免与接入链路的冲突。所以，该第一节点依然需要为中继节点配置若干可选的上行回传资源。
图14示出了一种提前调度上行回传资源和下行回传资源的示意图。如图14所示，该第一节点为该第二节点配置了一个固定回传资源(时隙0的控制区域)和多个动态下行回传资源(时隙0、2和4的数据区域)，同时，配置了多个可选的上行回传资源(时隙6、7和8)，与前述实施例结合，时隙0的控制区域为固定下行回传资源，时隙0、2与4的数据区域为动态下行回传资源，时隙6、7、8为可选的上行回传时隙。
上述实施例仅考虑了下行回传资源的配置，但在实际中，第一节点也需要配置第二节点的上行回传资源。上行回传资源可独立配置，也可与下行回传资源同时配置。
对于可选的上行回传资源配置可以由以下几种选择：
(1)所有可选的上行回传资源均配置为动态回传资源，并由DCI进行调度，如图14中，时隙6、7、8由前面的下行回传资源调度，而下行回传资源的HARQ反馈信息由下行DCI配置到其中任一时隙。在本例中，上行回传资源被独立配置。
(2)至少有一个固定的上行回传资源与下行固定回传资源绑定，该第二节点在下行固定回传资源处检测此固定上行回传资源的DCI，且至少下行部分动态回传资源对应的HARQ反馈将位于此固定上行回传资源，例如在图14中，将时隙6设置为固定上行回传时隙，其调度信息一般位于时隙0，且时隙0中PDSCH的HARQ反馈信息将位于时隙6。同时，第二节点发送的其余周期或半持续信号也可位于此上行固定回传时隙，例如，周期性或半持续SRS，用于周期或半持续CSI上报的PUCCH或PUSCH等。
在一种可能的实现方式中，其余动态回传资源所对应的HARQ反馈也将位于此上行固定回传时隙，例如，在图14中，时隙0、2、4的HARQ反馈信息均位于时隙6。若该第一节点为第二节点配置了多组下行回传资源，则每组下行回传资源中的固定下行回传资源均可绑定一个上行固定回传资源。
上行固定回传资源可以被直接配置，也可以由周期信号(例如PUCCH，SRS等)的配置位置间接得到。当下行回传资源(或上述第二动态回传资源)未传输数据时，上行固定回传资源可能也不进行上行回传链路发送。例如，当上行固定回传资源的PUCCH仅用于反馈下行回传资源(或上述第二动态回传资源)所传输PDSCH的HARQ-ACK信息，且第二节点未检测到上行固定回传资源的PUSCH所对应调度DCI时。
(3)在(2)的基础上，其余的上行回传资源可配置为动态回传资源。
在一种可能的实现中，每一个动态上行回传资源也和一个动态下行回传资源绑定，此动态上行回传时隙在所绑定的动态下行回传资源中被调度，且可能传输对应动态下行回传时隙的HARQ信息。
(2)和(3)均为上行回传资源与下行回传资源的联合配置，需配置两者的绑定或关联关系。
例如，图14中，固定上行回传时隙6对应于固定下行回传时隙0，而动态的下行回传时隙2和4分别对应于动态的上行回传时隙7和8，时隙7的调度DCI在时隙2中，而时隙8的调度信息在时隙4中。因此，若时隙2未被调度，则时隙7也不会被调度，时隙8同理。在这种情况下，时隙2的HARQ信息可能在时隙7中被反馈，也可能依然在时隙6中反馈。
在另外一种可能的实现中，第一节点向第二节点配置动态灵活时隙(即未指定上下行的时隙)，并将该灵活时隙与一个下行回传时隙绑定，第二节点通过检测此下行时隙的DCI，确定该动态灵活时隙是否被调度，以及传输方向(上行或下行)和传输参数。
在前述图6或图9或图12所述的实施例中，步骤S410，S510以及S610中，第一节点向第二节点发送资源配置信息，资源配置信息可以配置接入链路或回传链路的资源。
如果配置的是接入资源，接入资源还可以包括不可用资源，即，接入链路的资源包括：固定接入资源、动态接入资源和不可用接入资源(not available access resource)。
如果配置的是回传链路的资源，如前所述，资源配置信息包括：固定回传资源和动态回传资源。在上述不可用接入资源上不进行接入链路的传输。应理解，动态接入资源可以被配置为接入链路上的上行传输或下行传输；类似地，动态回传资源也可以被配置为回传链路上的上行传输或下行传输。
如果配置的是接入资源，第二节点接收第一节点发送的资源配置信息，资源配置信息用于指示接入资源集合的时域位置，接入资源集合包括至少一个固定接入资源和/或多个动态接入资源；第二节点接收第一节点发送的第一指示信息，第一指示信息用于指示多个动态接入资源中被调度的用于回传链路的动态接入资源的信息。进一步，第二节点在被调度的用于回传链路的动态接入资源上接收所述第一节点发送的信号。第二节点根据被调度的用于回传链路的动态接入资源的信息确定用于接入链路的动态接入资源。
上述调度的用于回传链路的动态接入资源的信息的含义包括动态接入资源中的部分或全部资源在第一指示信息中被指配为用于回传链路的传输。
接入资源集合中的不可用接入资源可以用于固定回传资源，即，当资源配置信息配置的是接入资源集合的时候，资源配置信息中的不可用接入资源用于回传链路的固定回传资源。应理解，这里并不限定接入资源集合中配置的不可用接入资源一定用于固定回传资源。而反过来，固定回传资源在接入链路上为不可用接入资源。
应理解，接入资源的配置粒度可以是一个时隙，也可能是多个时隙，还可能是多个符号等，本申请主要以时隙的配置粒度加以说明，但并不排除其余配置粒度。
上述资源配置信息可以由上级节点通过高层信令进行配置，上级节点包括控制节点，通常控制节点为宿主基站，具体可以为宿主基站的控制单元(control unit,CU)。高层信令包括RRC或者F1AP(F1 application,F1AP)信令。其中F1AP也可能是F1AP的增强或修改的版本。具体地，如果是配置回传链路的资源，那么可以通过RRC信令来进行配置，如果是配置接入链路的资源，则通过F1AP来进行配置。
应理解，上述第一节点可以是第二节点的上级节点，还可以是宿主基站。第二接收的资源配置信息可以来自于一个第一节点，而第二接收的第一指示信息来自另一个第一节点。即，第二节点接收的资源配置信息和第一指示信息来自于不同的第一节点。本申请仅为描述方便的需要，统一采用第一节点的名称。应理解，第一节点可以向第二节点转发来自宿主基站的资源配置信息。
因此，第一节点向第二节点发送资源配置信息包括：第一节点生成资源配置信息并发送给第二节点，或者第一节点转发来自宿主基站的资源配置信息。以下相同，不再赘述。
进一步，上述第二节点接收第一节点发送的资源配置信息，可以接收第一节点发送的接入链路的资源配置信息，还可以接收第一节点发送回传链路的资源配置信息。资源配置信息用于指示回传资源集合的时域位置，回传资源集合包括：至少一个固定回传资源和/或多个动态回传资源。
用于指示接入资源集合的资源配置信息和用于指示回传资源集合的资源配置信息通 过不同的信令或接口传输。例如，用于指示接入资源集合的资源配置信息通过F1AP信令或接口进行传输，而用于指示回传资源集合的资源配置信息通过RRC信令传输。
具体地，配置回传链路或接入链路的资源可以使用基于bitmap或字符串的方法进行配置，bitmap包含不可用接入资源指示和固定/动态接入资源的指示比特，不可用接入资源指示的优先级高于固定/动态接入资源指示。
具体方式如下：
方式一：基于两级bitmap的配置
采用两级bitmap进行接入链路的资源的配置时，其中，第一级bitmap用于指示不可用接入资源，第二级用于指示固定/动态接入资源，且不可用接入资源指示的优先级高于固定/动态接入资源指示，即被指示为不可用的接入资源，无论固定/动态资源的指示如何，均为不可用接入资源。
应理解，接入链路的不用可用接入资源也可以直接配置为接入链路的可用资源，未配置的资源不可用于接入链路传输。本申请以不可用接入资源为例，但并不排除配置接入链路的可用资源。以下不再赘述。
接入链路的资源配置如下：
接入资源配置：
Figure PCTCN2019093653-appb-000001
此外，由于中继节点可能存在多个小区/扇区/天线面板，不同的小区/扇区/天线面板可以配置不同的接入资源类型。因此，可能同时存在多个接入资源配置，通过接入资源编号可与小区/扇区/天线面板相关联。
上述接入资源配置中，不可用接入资源指示和固定/动态接入资源指示可以通过bitmap的方式表示。
图19为本实施例用bitmap表示接入链路资源分配的示例。图19中，指示的资源长度为10个时隙，在不可用回传资源指示中，比特1代表不可用资源。应理解，图19中仅以10个时隙为示例，实际系统中可以是20个时隙或其他任意数目的时隙，本申请不做限定。
类似地，在固定/动态回传资源指示中，比特1代表固定接入资源，比特0代表动态接入资源。
在此示例中，不可用接入资源指示的bitmap中第1,2,3位为1，表示时隙1,2,3为不可用接入时隙。固定/动态接入资源指示的bitmap中第0,4,5位为1，表示时隙0,4,5为固定接入时隙，在剩余时隙中，由于时隙1,2,3为不可用接入时隙，则时隙0,6,7,8,9为动态接入时隙，如图19中接入资源类型所示。
应理解，本申请并不将bitmap中的0或1与某种类型强制关联，即，在不可用资源指示中，可以用0指示不可用资源，也可以用1指示不可用资源；在固定/动态接入资源指示中，可以用0指示固定接入资源，1指示动态接入资源，反之亦然。
方式二：基于字符串的配置
上述bitmap的另一种实现中，可以通过字符串直接指示接入资源类型，具体配置可以如下：
接入资源配置：
Figure PCTCN2019093653-appb-000002
图20为一个示例，图20中以指示的资源长度为10个时隙资源为例，通过不同的字符指示每个时隙资源的类型。应理解，本申请不限制指示资源的长度，10个时隙仅仅是一种示例，还可以是20个时隙或任何其他数量的时隙。表1为一种字符与接入资源类型对应关系：
表1字符与接入资源类型对应关系表
U 不可用接入资源
H 固定接入资源
S 动态接入资源
应理解，表1仅是一个示例，本申请对具体的字符不做限定，例如，不可用接入资源U也可以用N表示。在一种可能的实现中，上述方式一中基于两级bitmap的配置也可以用一个bitmap来进行表示，如图21所示。具体地，可以将一个bitmap每两个比特一组，分别对应每个时隙。其中第一个比特表示可用或不可用接入资源，第二个比特表示固定/动态接入资源，可以用0指示固定接入资源，1指示动态接入资源，反之亦然。图21中，仍以10个时隙为例，当实际并不限定时隙个数。每个比特组的第一个比特为0标识资源可用于接入链路，比特1代表不可用资源，反之亦然。每个比特组的第二个比特为0表示动态接入资源，1表示固定资源，反之亦然。
如前所述，第一节点为第二节点配置接入资源集合，而第二节点通过接入资源集合推断出回传资源集合。具体地，可以根据接入资源类型与回传资源类型对应关系可以获得回传链路的资源配置，接入资源类型与回传资源类型对应关系可以如下表2所示。
表2接入资源类型与回传资源类型对应关系表
不可用接入资源 固定回传资源
固定接入资源 不可用回传资源
动态接入资源 动态回传资源
在上述对应规则下，第一节点获得接入链路的资源配置后，就可以获得对应的回传链路资源配置。
应理解，上述仅是一个示例。在一种可能的实现中，资源配置信息中还可以包括回传链路的不可用资源配置和/或固定回传资源，而不采用上述表2中的对应关系。而回传链路的固定回传资源在接入链路上为不可用接入资源。对应地，接入链路的固定接入资源，在回传链路上为不可用回传资源。应理解，接入链路的不可用接入资源可能不全部 都是回传链路的固定回传资源，依赖于协议定义，本申请不做约束。对应地，回传链路的不可用资源可能也不全部都是接入链路的固定接入资源。
在另一种可能的实现中，控制节点，如宿主基站，通过F1AP对接入链路的资源进行配置，接入链路的资源包括不可用接入资源、固定接入资源、动态接入资源，而通过RRC信令对回传链路的资源进行配置，回传链路的资源包括不可用回传资源、固定回传资源、动态回传资源。应理解F1AP也可能是F1AP的增强或修改版本，本申请不做限制。
应理解，回传链路的不可用回传资源可以不存在，即，回传链路的资源配置仅包括固定回传资源和动态回传资源。其中动态回传资源是用于回传链路的上行传输还是下行传输，可以通过前述调度方法实现，不再赘述。
前述实施例通过提前调度来实现动态回传资源的分配。提前调度可以是在固定传输时隙或子帧实现多个动态回传资源的调度，如图7、图8、图10或图11所述的实施例，而在图13或图14所述的实施例中，提前调度并不局限于固定时隙。
因此，前述实施例的调度方法包括：第二节点接收第一节点发送的资源配置信息，资源配置信息用于指示回传资源集合的时域位置，回传资源集合包括至少一个固定回传资源和/或多个动态回传资源；第二节点接收第一节点发送的第一指示信息，第一指示信息用于指示多个动态回传资源中被调度的动态回传资源的信息。进一步，第二节点在被调度的动态回传资源上接收第一节点发送的信号。
其中，第二节点接收第一节点发送的第一指示信息并不局限于固定回传时隙。
类似地，由于第一节点为第二节点配置的资源配置信息也可以是接入资源集合，因此，上述方法也包括：第二节点接收第一节点发送的资源配置信息，资源配置信息用于指示接入资源集合的时域位置，接入资源集合包括至少一个固定接入资源和/或多个动态接入资源；第二节点接收第一节点发送的第一指示信息，第一指示信息用于指示多个动态接入资源中被调度的动态接入资源的信息。进一步，第二节点在被调度的用于回传链路的动态接入资源上接收第一节点发送的信号。
第二节点在回传链路的下行传输时隙或子帧上接收第一指示信息，下行传输时隙或子帧包括：固定回传资源和被调度的用于回传链路的动态接入资源被配置为下行传输的时隙或子帧。即，第一指示信息可以在任何已经被配置为回传链路的下行时隙或子帧上进行传输，下行传输时隙或子帧可以不限于固定回传时隙，也可以在被配置为下行传输的动态回传资源上进行传输。
应理解，第一节点可以为第二节点配置接入资源集合，也可以为第二节点配置回传资源集合，还可以为第二节点既配置接入资源集合，也可以为第二节点配置回传资源集合。如果第一节点为第二节点配置的是接入资源集合，接入资源集合中的动态接入资源可以在接入链路和回传链路之间动态配置，即，由第一指示信息来配置回传链路的动态资源，从而根据接入资源集合中的动态接入资源就可以确定可以用于接入链路的动态资源。
对应地，如果第一节点为第二节点配置的是回传资源集合，回传资源集合中的动态回传资源可以在接入链路和回传链路之间动态配置，还是通过第一指示信息来配置回传链路的动态资源，从而根据回传资源集合中的动态回传资源就可以确定可以用于接入链路的动态资源。
如果第一节点为第二节点分别配置接入资源集合和回传资源集合，那么可以只在接入资源集合或者回传资源集合中配置动态资源。也可以在接入资源集合和回传资源集合中都配置动态资源，本申请不做限定。
在一种可能的实现中，基于前述图6或图9或图12所述的实施例，在步骤S410，S510以及S610中完成资源配置信息后，第一节点也可以通过第一指示信息来激活、增加、减少、替换、或去激活动态回传资源。
图22为激活或去激活回传链路动态资源的示意图。假定在时隙0的时候，第一节点向第二节点发送资源配置信息，第二节点接收第一节点发送的资源配置信息，资源配置信息用于指示回传资源集合的时域位置，回传资源集合包括至少一个固定回传资源和/或多个动态回传资源。如前所述，资源配置信息可以是bitmap的方式来进行配置的，配置可以是接入链路的资源，也可以是回传链路的资源，本申请不做限定。
图22中，假定时隙0和1为回传链路的固定回传资源。其中时隙2、5、6和8为动态回传资源，图中以填充表示，即，动态回传资源可以用于接入链路，也可以用于回传链路。在时隙1的时候，第一节点向第二节点发送激活动态回传资源的指示。激活动态回传资源可以通过PDCCH调度来实现，也可以通过MAC层的MAC CE来实现，具体采用哪种信令本申请不做约束。
如果通过PDCCH来实现，具体地可以通过一个特定的扰码实现回传链路动态回传资源的激活，例如，可以定义一个灵活调度的无线网络临时标识(flexible scheduling radio network tempory identity,FS-RNTI)，应理解，这里的FS-RNTI也可以是别的名称，本申请对此不做限定。比如，FS-RNTI可以是一个16比特的标识，用来对PDCCH的循环冗余校验(Cyclic Redundancy Check,CRC)进行扰码。通过FS-RNTI就可以识别该PDCCH是用于回传链路动态回传资源的激活、增加、减少、替换、或去激活操作。
在经FS-RNTI扰码或MAC CE中，指示哪些动态回传资源将被真正用于回传链路的传输，而没有被指示或配置的动态回传资源可以用于接入链路的传输。例如，图22中指示时隙2和8用于回传链路的传输，而时隙4和6则没有被配置用于回传链路的传输，因此时隙4和6可以用于接入链路的传输。
类似于前面的bitmap的配置方法，在激活动态回传资源的指示中可以采用bitmap的方式指示回传链路的资源。在采用PDCCH进行激活的时候，由于采用了特定的扰码，可以对PDCCH的内容重新定义。例如，可以用1个比特来指示是激活还是去激活动态回传资源。当然，也可以采用2个比特来表示激活、增加、减少或去激活回传链路的动态回传资源。剩余的比特可用于bitmap进行回传链路的资源指示。例如，如果将时隙2和时隙8配置为回传链路资源，那么bitmap的值可以是”0010000010”。应理解，这里的bitmap仅用于动态回传资源的指示，仅以10个时隙为例，也可以是其他的时隙数，本申请不做限制。
在一种可能的实现中，为了压缩PDCCH的bitmap的长度，也可以仅指示动态回传资源时隙。由于在之前已经有资源配置信息，例如资源配置信息中配置时隙2、4、6、8为动态接入资源或动态回传资源，那么可以按照顺序用4个比特来指示动态回传资源的配置。例如，将时隙2和时隙8配置为回传链路的传输，则采用4个比特”1001”来表示4个动态回传资源的配置。
进一步，可以配置用于回程链路的动态回传资源是用于下行传输还是上行传输，因 此，需要进一步配置另一个bitmap用于指示所配置的用于回传链路的动态回传资源是上行还是下行。例如，假定时隙2用于上行，时隙8用于下行，那么对应的bitmap可以是“0000000010”，其中第2比特为0表示上行，第8比特为1表示下行，反之亦然。进一步，还可以用两个比特来表示如，用“01”来表示，因为仅有2个动态回传资源被配置为用于回程链路的传输。
上述采用bitmap的配置方式适用于基于PDCCH或MAC CE激活动态回传资源的方法。上述仅以时隙为例，但本申请并不限定，还可以是以子帧或符号或帧为粒度进行配置。
一旦完成了回传链路的动态回传资源的激活，激活的用于回传链路的动态回传资源的下行时隙和正常的时隙没有任何区别，因此，可以进行正常的调度和操作。因此，可以在每个激活的动态回传资源时隙和/或固定回传资源时隙进行进一步的回传链路资源的重新配置。
重新配置包括增加新的回传链路的动态回传资源，减少回传链路的动态回传资源，或者替换回传链路的动态回传资源。其中，替换回传链路的动态回传资源包括将部分配置的用于回传链路的动态回传资源替换为另一部分动态回传资源。具体的方法类似于上述激活的方法，采用基于bitmap的方法，不再赘述。如果是替换回传链路的动态回传资源，则可以通过两个bitmap来实现，一个是指示哪些动态回传资源被替换，另一个指示用于回传链路的新的动态回传资源。
应理解，上述激活、重新配置或去激活回传链路的动态回传资源的信令中包含一个操作指示字段，用于指示信令是用于激活、增加、减少、替换或去激活操作。具体的可以通过，例如3个比特来表示，不同的值表示不同的操作，具体的取值本申请不做限定。
对于去激活操作，可以通过上述信令中的操作指示字段来进行识别，可以不包括其他字段，也可以包括一个原因字段，用于指示去激活的原因。去激活操作将释放回传链路上所有的动态回传资源。
应理解，上述激活、重新配置或去激活回传链路的动态回传资源的信令可以在所有的下行资源上传输，即，可以是在固定回传资源或动态回传资源上传输的。
应理解，本申请中的资源配置信息还可以包括物理节点的标识符(identifier,ID)，也可以是保护资源配置信息的信令或消息和物理节点的ID相关联。如第二节点的ID，第二节点通过标识符确定是否接收该资源配置信息。如果资源配置信息包含或关联的物理节点ID和接收节点的ID不同，则可以转发包含资源配置信息的消息或信令。如果资源配置信息包含或关联的物理节点ID和接收节点的ID相同，则接收资源配置信息，并进行处理。以下不再赘述。
在一种可能的实现中，接入资源集合还可以进一步包含其余节点的接入链路的配置信息。例如，宿主基站为第一节点通知其他节点的回传和/或接入资源的配置，其他节点包括第一节点的下级节点或潜在下级节点，潜在下级节点为有可能会成为第一节点下级节点的IAB节点，从而使得第一节点可以更好地控制调度。以下相同，不再赘述。
通过上述方法，可以实现更加灵活的回传链路上的动态资源的激活、增加、减少、替换或去激活，控制也更加快速，减小了控制区域的开销。在采用PDCCH实现上述操作时，仅通过盲检就可以区分PDCCH是否用于动态回传链路的资源调整。如果通过MAC CE，也非常的快速，减小实现的复杂度。
在一种可能的实现中，上述通过PDCCH或MAC CE进行回传链路动态回传资源分配的方法，可以通过反馈进行确认，以保证第一节点和第二节点之间的资源不会出现冲突。因此，第二节点收到第一节点的动态回传资源分配后进行响应是一种可行的方法。
具体地，第二节点接收到第一节点发送PDCCH对回传链路的动态回传资源进行调度或分配后，第二节点向第一节点发送响应消息，响应消息包括肯定响应和否定响应，如响应消息可以是ACK或NACK。第一节点收到第二节点发送的响应消息后，才开始在调度的资源上进行传输。
如果是采用MAC CE进行回传链路的动态回传资源的调度或分配时，MAC层也发送确认消息，方法类似，不再赘述。
应理解，前述实施例中主要以接入资源集合或回传资源集合作为例子说明具体实施方式。对以接入资源集合为例的实施例，对回传资源集合的方法是类似的，可以通过简单置换即可以得到对应的回程资源集合的方法。对以回程资源集合为例的实施例，对接入资源集合的方法也是如此。仅出于篇幅的需要，不再赘述。
在一种可能的实现中，第一节点可以可以在资源配置信息中包括至少一个固定回传资源和至少一个动态资源。至少一个动态资源用于在第二节点的接入链路和回传链路之间动态分配。部分或全部动态资源是用于接入链路还是回传链路，通过第二节点的调度来实现。
具体地，该方法包括：第一节点向第二节点发送资源配置信息，资源配置信息用于指示至少一个固定回传资源和至少一个动态资源；第一节点向第二节点发送第一指示信息，第一指示信息用于指示至少一个动态资源中被调度的用于回传链路的动态资源的信息。
在一种可能的实现中，第一节点向第二节点发送第二指示信息，第二指示信息用于重新指配至少一个动态资源中用于回传链路的动态资源的信息。
第二指示信息用于对动态资源进行重新分配。应理解，前述通过调度的方式对动态接入资源或动态回传资源以及动态资源的指配可以是半静态的，即，每次调度之后，指配的用于回传链路的资源就被认为是用于回传链路的资源，直到下一次调度为止。
通过第二指示信息可以实现动态资源的重新指配。应理解，第二指示信息对前述实施例中的动态接入资源和/或动态回传资源同样适用，不再赘述。
在一种可能的实现中，第一节点在回传链路的下行传输时隙或子帧上向第二节点发送第二指示信息，下行传输时隙或子帧包括：固定回传资源和被调度的用于回传链路的动态资源中被配置为下行传输的时隙或子帧。
第二指示信息的传输不限于固定回传资源，也可以在已经被调度的用于回传链路的动态资源上进行传输。应理解，这里的用于传输第二指示信息的固定回传资源或已经被调度的用于回传链路的动态资源在回传链路上都应该是被配置为下行传输的资源。应理解，本申请中的资源包括时域资源、频域资源，时频资源，码域资源，本申请不做限定。
在一种可能的实现中，资源配置通过基于bitmap或字符串的方法进行配置。具体的bitmap的配置方法和表示方法如前所述，不再赘述。应理解，通过bitmap或字符串的方式来进行配置时，可以是在PDCCH或MAC CE中采用bitmap的配置方式，本申请不做 限定。
在一种可能的实现中，第一节点发送第一指示信息或第二指示信息后，接收第一节点发送响应消息。具体的响应如前所述，不再赘述。
应理解，上述是从第一节点的角度进行描述的，对第二节点，具有类似的方法：
第二节点接收第一节点发送的资源配置信息，资源配置信息用于指示至少一个固定回传资源和至少一个动态资源；
第二节点接收第一节点发送的第一指示信息，第一指示信息用于指示至少一个动态资源中被调度的用于回传链路的动态资源的信息。
在一种可能的实现中，第二节点根据被调度的用于回传链路的动态资源的信息确定至少一个动态资源中用于接入链路的动态资源。
在一种可能的实现中，第二节点接收第一节点发送的第二指示信息，第二指示信息用于重新指配至少一个动态资源中用于回传链路的动态资源的信息。
在一种可能的实现中，资源配置通过基于bitmap或字符串的方法进行配置。
在一种可能的实现中，第二节点在回传链路的下行传输时隙或子帧上接收第二指示信息，下行传输时隙或子帧包括：固定回传资源和被调度的用于回传链路的动态资源中被配置为下行传输的时隙或子帧。
在一种可能的实现中，第二节点接收到所述第一指示信息或第二指示信息后，向所述第一节点发送响应消息。
具体的实现可以参考前面的方法，不再赘述。
本申请实施例的资源确定的方法，通过配置回传链路的固定回传资源和动态资源，可以使得第二节点获得动态资源，动态资源可以在接入链路和回传链路之间共享，提升了资源利用了，使得中继节点的资源调度更加灵活，实现快速的接入链路和回传链路之间的资源协调。
在一种可能的实现中，对上述第二节点接收的动态接入资源，动态回传资源或动态资源，统一称为软(soft)资源，所谓soft资源的含义包含可以被用于接入链路或回传链路的资源。而前述实施例中的固定接入资源和/或固定回传资源又可以称为硬(hard)资源。
因此，前述方法还进一步包括：第二节点获取soft资源；第二节点接收第一节点发送的第一指示信息，第一指示信息用于指示soft资源中被调度的用于回传链路的soft资源的信息。
在一种可能的实现中，第二节点根据被调度的用于回传链路的soft资源的信息确定至少一个soft资源中用于接入链路的动态资源。
