资源复用指示方法、装置和中继节点
交叉引用
本发明要求在2020年08月06日提交中国专利局、申请号为202010785266.7、发明名称为“资源复用指示方法、装置和中继节点”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请涉及通信领域，尤其涉及一种资源复用指示方法、装置和中继节点。
背景技术
目前，在新空口(New Radio，NR)系统中，接入回传一体化(Integrated AccessBackhaul，IAB)可以为NR小区提供扩展覆盖，也可以为NR小区增强容量，其中，支持用户设备(User Equipment，UE，也可称之为终端设备)的无线接入并且将数据进行无线回传的接入节点称为IAB节点(IAB node，IABN)。而为IAB节点提供无线回传功能以使得UE与核心网(Core Net，CN)连接的接入节点称为宿主IAB节点(donor IAB node)，宿主IAB与核心网之间进行有线传输。UE和接入节点之间通过无线接入链路(access link)传输UE的数据，接入节点之间可通过无线的回传链路(backhaul link)传输UE的数据。
在支持集中式单元(CentralUnit，CU)/分布式单元(Distributed Unit，DU)分离部署的IAB网络架构中，一个IAB节点(IAB Node，IABN)包括DU功能模块和移动终端(Mobile Termination，MT)功能模块。依靠MT功能模块，一个接入节点(即IABN)可以找到一个上游接入节点(即Parent IABN，P-IABN)，并与上游接入节点的DU建立无线的回传链路。在一个IAB节点建立完整的回传链路后，该IAB节点打开其DU功能，DU会提供小区服务， 即DU可以为UE提供接入服务。其中，一个自回传回路包含一个宿主IAB节点，该自回传回路中所有的IAB节点的DU功能模块可以都连接到一个CU节点即宿主IAB节点的CU功能模块。
另外，在IAB网络架构中，MT功能模块和DU功能模块之间的资源复用方式可以包括频分复用(Frequency Duplex Multiplexing，FDM)、空分复用(Spatial Duplex Multiplexing，SDM)或同时同频全双工(Co-frequencyCo-timeFullDuplex，CCFD)复用。但是，IAB节点的MT功能模块的资源配置及调度是由父IAB节点通过无线资源控制(Radio Resource Control，RRC)信令、下行控制信息(Downlink Control Information，DCI)配置的，IAB节点DU功能模块的资源配置是由donor CU进行配置。然而，父IAB节点在调度IAB节点的MT功能模块资源传输时，并不知道IAB节点的DU功能模块待发送的数据，IAB下一跳节点(即IAB节点的MT功能模块或UE)的上行链路(Uplink，UL)数据，进而不知道MT功能模块和DU功能模块之间的复用调度是否可以实现，可能会造成IAB节点资源使用不充分，频谱使用效率降低。
因此，如何配置或调度MT功能模块和DU功能模块的资源，以在IAB节点实现不同的复用方式，避免MT功能模块和DU功能模块之间不匹配，成为亟待解决的技术问题。
发明内容
本申请实施例的目的是提供一种资源复用指示方法、装置和设备，以能够解决IAB节点资源使用不充分，频谱使用效率低的问题。
第一方面，提供了一种资源复用指示方法，应用于中继节点，所述方法包括：基于目标信息确定中继节点的复用模式，所述目标信息包括以下至少一项：复用模式指示信息；定时模式信息；资源类型信息。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部 分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6 th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle UE，VUE)、行人终端(Pedestrian UE，PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
在本申请实施例中，在IAB网络中跨跳使用SDM、FDM或CCFD时，涉及UE或子IAB节点(Child IAB Node，C-IABN，可称为第一节点)、本IAB节点(称为第二节点或第一IAB节点)以及本IAB节点的父IAB节点(Parent IAB Node，P-IABN，称为第三节点或第二IAB节点)。其中，各跳的数据传输分别是由不同的IAB节点调度，即第一节点和第二节点之间的这一跳Hop1(即第一跳)的数据传输由第二节点即第一IAB节点调度，第二节点和第三节点之间的这一跳Hop2(即第二跳)的数据传输由第三节点即第二IAB节点调度，如图2所示。
其中，上述SDM，是指一个IAB节点在同样的时频资源上同时从其父IAB节点接收物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，以及从其子IAB节点或UE接收物理上行共享信道(Physical Uplink Shared Channel，PUSCH)；或者一个IAB节点在同样的时频资源上同时向其父IAB节点发送PUSCH，以及向其子IAB节点或UE发送PDSCH。
上述频分复用FDM，是指一个IAB节点在不同的频率资源上同时从其父IAB节点接收PDSCH，以及从其子IAB节点或UE接收PUSCH；或者一个IAB节点在不同的频率资源上同时向其父IAB节点发送PUSCH，以及向其子IAB节点或UE发送PDSCH。
上述同时同频全双工，是指一个IAB节点在同样的时频资源上同时从其父IAB节点接收PDSCH，以及向其子IAB节点或UE发送PDSCH；或者一个IAB节点在同样的时频资源上同时向其父IAB节点发送PUSCH，以及从其子IAB节点或UE接收PUSCH。多面板发送接收(Multiple PanelTransmission Reception，MPTR)是IAB节点使用不同的天线模块(panel)来同时分别进行收发的技术，例如一个IAB节点装备两个天线模块，其中一个模块接收时，另一个模块发送。MPTR的收发天线模块之间可以有较大的隔离度，可以一定程度上减少发送对接收造成的干扰。
IAB节点的DU功能模块和MT功能模块之间的双工(Duplexing)方式分为半双工(Half duplex)和全双工(Full duplex)的方式。在Full duplex的情况下，DU功能模块/MT功能模块可以同时收发。因此，其在FDM或者SDM的复用方式下，DU功能模块和MT功能模块的收发操作方式有以下几种。
(1)DU-TX&MT-TX。即，DU功能模块配置为下行链路(Downlink，DL)，MT功能模块配置为上行链路(Uplink，UL)；或DU功能模块存在实际的DL发送，MT功能模块存在实际的UL发送。
(2)DU-RX&MT-RX。即，DU功能模块配置为UL，MT功能模块配置为DL；或DU功能模块存在实际的UL接收，MT功能模块存在实际的DL 接收。
(3)DU-TX&MT-RX。即，DU功能模块配置为DL，MT功能模块配置为DL；或DU功能模块存在实际的DL发送，MT功能模块存在实际的DL接收。
(4)DU-RX&MT-TX。即，DU功能模块配置为UL，MT功能模块配置为UL；或DU功能模块存在实际的UL接收，MT功能模块存在实际的UL发送。
综上，IAB节点的MT功能模块和DU功能模块之间有以下几种复用方式。
(1)SDM TX：MT TX，DU TX。
(2)SDM RX：MT RX，DU RX。
(3)FDM TX：MT TX，DU TX。
(4)FDM RX：MT RX，DU RX。
(5)MPTR UL：MT TX，DU RX。
(6)MPTR DL：MT RX，DU TX。
(7)MT TX，MT RX，DU TX，DU RX同时支持。
其中，DU TX和DU DL都可以通用，MT TX和MT UL可以通用，DU RX和DU UL可以通用，MT RX和MT DL可以通用
另外，对于IAB节点的DU功能模块的资源配置，Donor节点通过F1-C以及信令gNB-DU resource configuration来配置DU功能模块的资源。其中，包括DL/UL/flexible symbol的配置，配置每个时隙中符号的传输的类型。包括硬(hard)、软(soft)、不可用(not available，NA)、共享(shared)类型等的配置，配置每个类型的符号DU的可用情况。
具体的，若DL/UL/flexible symbol被配置为hard，则IAB节点的DU功能模块可以在该符号上发送/接收/发送或者接收。若DL/UL/flexible symbol被配置为soft，若IAB节点的DU功能模块的发送/接收/发送或接收不影响MT功能模块的发送或接收时，IAB节点的DU功能模块可以在该符号上发 送/接收/发送或接收；否则，在该符号上不进行发送/接收/发送或接收。进一步地，父IAB节点可以通过DCI format 2-5指示IAB节点的DU功能模块的soft symbol的可用情况。若DL/UL/flexible symbol被配置为NA，则IAB节点的DU功能模块在该符号上不发送也不接收。
IAB节点的MT功能模块的资源配置，由父IAB节点，通过RRC信令、DCI信令等配置下来的，MT的资源类型为DL/UL/Flexible。
其中，Flexible配置可以等同于DL/UL配置处理，可以独立于DL/UL配置处理。

进一步可选的，所述反馈指示信息用于指示反馈资源，所述反馈资源用于传输所述反馈信息；其中，所述反馈指示信息包括时域资源指示信息和频域资源指示信息中的至少一项。
可选的，所述反馈指示信息可以携带在父IAB节点发送的激活信令中，比如DCI信令、MAC CE信令。其中，所述时域资源指示信息可以为时域间隔指示信息，或者用于指示反馈资源与接收的DCI信令或MAC CE信令之间的间隔。
进一步可选的，接收所述激活信令或去激活信令的资源与反馈资源之间的关系基于协议约定或预配置确定。也就是说，可以通过预定义/预配置反馈资源与接收激活/去激活信令之间的关系，以获取反馈资源的位置。在一个示例中，IAB节点的MT功能模块，可以根据接收的激活/去激活信令的资源，以及定义的规则，获取反馈资源的信息，继而在所述反馈资源上发送反馈信息。若父IAB节点未接收到反馈信息，则认为该激活/去激活信令传输失败。
在本申请的资源复用指示方法的一个具体实施例中，IAB donor通过F1-C信令为IAB节点配置在每个时隙中UL/DL/flexible symbol的复用模式。可选值为协议预定义复用模式指示信息为IAB的双工方式，可选配置包括：MT TX；MT RX；DU TX；DU RX；MT TX，DU RX；MT RX，DU RX；MT TX，DU TX；MT TX，DU TX；MT TX，MT RX；DU TX，DU RX；MT TX，MT RX，DU TX，DU RX。父IAB节点获取IAB节点的DU功能模块的配置信息，发送DCI format 2-6用于激活/去激活时域资源上的复用模式。
在本申请的资源复用指示方法的另一个具体实施例中，协议预定义复用规则，若IAB节点的MT功能模块和IAB节点的DU功能模块支持使用相同时频域，则IAB节点的MT功能模块和IAB节点的DU功能模块支持SDM复用；若IAB节点的MT功能模块和IAB节点的DU功能模块配置相同的时域资源，不同的频域资源，则IAB节点的MT功能模块和IAB节点的DU功能模块指示FDM/SDM复用。IAB donor发送F1-C配置DU功能模块在时隙k上为DL，可用的PRB为20-39；父IAB节点配置时隙k上MT为UL，调度的PRB为0-19。根据预定义的规则，IAB节点在时隙k上可以支持FDM复用。其中，基于父IAB节点可以获取DU功能模块的时频域资源配置信息，根据DU功能模块的资源信息，调度IAB节点的MT功能模块。也就是父IAB节点根据DU功能模块的资源来调度MT功能模块。
在本申请的资源复用指示方法的再一个具体实施例中，协议预定义根据IAB节点的定时模式，确定IAB的复用模式。IAB donor通过F1-C信令指示 IAB节点其在时域上的复用模式，可选配置为：timing mode case 1；timing mode case 6；timing mode case 7；timing mode case 6和timing mode case 7。IAB节点根据F1-C信令确定复用状态。具体地：若为timing mode case 1，则MT功能模块和DU功能模块为TDM复用。若为timing mode case 6，则MT功能模块和DU功能模块可支持FDM/SDM TX。若为timing mode case 7，则MT功能模块和DU功能模块可支持FDM/SDM RX。若为timing mode case 6和timing mode case 7，则MT功能模块和DU功能模块可支持FDM/SDM TX/RX。进一步地，父IAB节点发送DCI激活/去激活IAB节点的复用状态。
在本申请的资源复用指示方法的又一个具体实施例中，协议预定义复用模式指示信息为IAB节点的双工方式，预定义双工方式对应的表格，一种表格方式配置如下表格1所示，则指示的候选值为：0，1，2，3，4，5，6，7。IAB donor通过F1-C配置IAB DU的双工方式及资源配置信息。可选值为[0:7]。IAB节点的MT功能模块将IAB节点期望的复用方式通过MAC CE信令上报给父IAB节点，IAB父节点可以根据TDD配置/buffer状态，通过DCI信令指示IAB节点其激活/去激活的时域资源的复用。其中，该DCI信令采用DCI format 2-5指示，若DCI format 2-5指示为Hard，则表示该资源上指示的复用模式为激活状态，否则，为去激活状态。
