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和网络设备12，网络设备可以理解为IAB节点(IAB node)。IAB节点包括DU功能部分和移动终端(Mobile Termination，MT)功能部分。依靠MT，一个接入点(即IAB node)可以找到一个上游接入点(parent IAB node)，并跟上游接入点的DU建立无线连接，该无线连接被称为回传链路(backhaul link)。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可以为终端(User Equipment，UE)11提供接入服务。也可以为下一跳IAB节点的MT提供服务。一个自回传回路包含一个宿主(donor)IAB节点(也可以称之为IAB Donor)，donor IAB节点有直接相连的有线传输网。应理解，上述接入点可以称之为节点，上述上游接入点可以称之为父节点。
其中，终端11也可以称作终端设备或者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(VUE)、行人终端(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。
参照图2，图2为一个IAB系统的中心单元(Central unit，CU)-DU结构图。在一个自回传回路中，所有的IAB节点的DU都连接到一个CU节点，由这一个节点通过F1-AP协议对DU进行配置。DU通过无线资源控制(Radio Resource Control，RRC)协议，对MT进行配置。Donor IAB节点没有MT功能部分。
为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、DU和MT的双工(duplexing)方式。
IAB节点的DU和MT之间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/MT可以同时收发，也就是一个功能模块接收信息，同时另一个功能模块发送信息。因此，其在频分复用(Frequency Division Multiplex，FDM)或者空分复用(Space Division Multiplexing，SDM)的复用方式下，DU和MT的收发操作方式有以下几种：
DU发送(DU-TX)且MT-TX。即，DU配置为下行(Downlink，DL),MT配置为上行(Uplink，UL)；或DU存在实际的DL发送，MT存在实际的UL发送；
DU接收(DU-RX)且MT-RX。即，DU配置为UL，MT配置为DL；或DU存在实际的UL接收，MT存在实际的DL接收；
DU-TX且MT-RX。即，DU配置为DL，MT配置为DL；或DU存在实际的DL发送，MT存在实际的DL接收；
DU-RX且MT-TX。即，DU配置为UL，MT配置为UL；或DU存在实际的UL接收，MT存在实际的UL发送。
二、复用方式。
SDM、FDM和对面板发送接收(Multiple Pannel Transmisson Reception，MPTR)三种复用方式均涉及跨跳之间的协调调度。
其中，SDM是指一个IAB节点在同样的时频资源上同时从其IAB父节点接收物理下行共享信道(Physical downlink shared channel，PDSCH)和从其子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IAB父节点发送PUSCH和向其子IAB节点或UE发送PDSCH。
FDM是指一个IAB节点在不同的频率资源上同时从其IAB父节点接收PDSCH和从其子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IAB父节点发送PUSCH和向其子IAB节点或UE发送PDSCH。
Full Duplex是指一个IAB节点同时从其IAB父节点接收PDSCH和向其子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IAB父节点发送PUSCH和从其子IAB节点或UE接收PUSCH；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。
如图3所示，显示了IAB网络中跨跳基于SDM/FDM/MPTR的调度关系。其中第一节点IABN(IAB node)与第三节点UE或子IAB节点(Child IAB node，C-IABN)之间的一跳(Hop)称为Hop1，由第一节点调度；第三IAB节点与第二节点之间的一跳成为Hop2，由第二节点调度。该第二节点为第一节点的IAB父节点(Parent IAB node，P-IABN)，此时上述第一节点中DU和MT的之间具有以下复用方式：
复用方式1(SDM TX)：MT TX，DU TX；
复用方式2(SDM RX)：MT RX，DU RX；
复用方式3(FDM TX)：MT TX，DU TX；
复用方式4(FDM RX)：MT RX，DU RX；
复用方式5(MPTR UL)：MT TX，DU RX；
复用方式6(MPTR DL)：MT RX，DU TX。
三、DU的资源配置。
Donor node CU通过gNB-DU资源配置(resource configuration)信令来配置DU的资源。其中，配置每个时隙中符号的传输的方向，符号(symbol)方向包括以下至少一项：DL符号、UL符号和灵活上下行(flexible)符号。配置DU的每个类型的符号的可用情况，包括硬(hard)、软(soft)和不可用(not available)类型的配置；其中，可用情况，是以符号类型为配置单位的，具体的包括以下情况：
若第一对象被配置为hard，则IAB DU可以自主在该符号上执行对应的第一操作；该第一对象可以包括DL、UL和柔性符号(flexible symbol)中的任一项，例如，该第一对象为DL symbol时，则第一操作为发送，若第一对象为UL symbol时，第一操作为接收，若第一对象为flexible symbol时，则第一操作为发送或者接收。
若DL/UL/flexible symbol被配置为soft，若IAB DU的第一操作不影响MT的发送或接收时，IAB DU可以在该符号上执行第一操作；否则，在该符号上不执行第一操作。进一步地，IAB父节点可以通过下行控制信息(Downlink Control Information，DCI)格式(format)2-5指示IAB DU的时隙符号(soft symbol)的可用情况；
若DL/UL/flexible symbol被配置为not available，则IAB DU在该符号上不发送也不接收。
四、MT的资源配置。
MT的资源是由CU/父节点配置，通过RRC信令中的时分复用(Time Division Duplex，TDD)配置(configuration)、DCI信令等配置下来的。MT的资源类型为DL/UL/Flexible symbol。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的传输处理方法、装置及通信设备进行详细地说明。
请参见图4，图4是本申请实施例提供的一种传输处理方法的流程图，该方法由第一节点执行，如图4所示，包括以下步骤：
步骤401，接收第二节点发送的第一指示信息或者向第二节点发送第一 指示信息，所述第一指示信息用于指示所述第一节点的目标复用方式；
其中，所述第二节点为宿主节点或为所述第一节点的父节点。
本申请实施例中，上述第一节点可以理解为IAB节点。该目标复用方式可以理解为，第一节点中DU和MT最终传输呈现的复用状态，具体地，该目标复用方式可以包括以上复用方式1至6中的任一项。
可选地，在一些实施例中，可以由第二节点决定第一节点的复用方式，此时，第一节点的行为为：接收第二节点发送的第一指示信息。例如，第二节点可以首先在多个复用方式中确定第一节点的目标复用方式，然后基于选择的目标复用方式，向第一节点发送第一指示信息。
在一些实施例中，可以由第一节点自行决定当前的复用方式，此时，第一节点的行为为：向第二节点发送第一指示信息。例如，第一节点首先在多个复用方式中确定第一节点的目标复用方式，然后基于选择的目标复用方式，向第二节点发送第一指示信息，以通知第二节点，当前选择的目标复用方式。
本申请实施例中的复用方式可以理解为调度计划，也就是说，上述目标复用方式可以理解为目标调度计划，例如，在一些实施例中，上述第一指示信息还可以用于指示以下至少一项：DU的调度和MT的调度。换句话说，在本申请实施例中，第一指示信息可以通过指示DU的调度和/或MT的调度，基于DU的调度和/或MT的调度确定第一节点的复用方式。
本申请实施例中通过接收第二节点发送的第一指示信息或者向第二节点发送第一指示信息，所述第一指示信息用于指示所述第一节点的目标复用方式；其中，所述第二节点为宿主节点或为所述第一节点的父节点。这样，由于第一节点或者第二节点可以决定第一节点的目标复用方式，并通过第一指示信息指示第一节点的目标复用方式，从而可以通过第一指示信息动态的调整第一节点的复用方式，提高了复用传输的可靠性，与此同时提升了系统传输的效率，降低传输时延。
可选地，在一些实施例中，所述方法还包括：
按照所述目标复用方式进行传输或者调度。
可选地，第一节点按照所述目标复用方式进行传输或调度，可以理解为包括以下至少一项：
第一节点中的DU可以按照所述目标复用方式进行传输或者调度；例如，第一节点中的DU可以按照目标复用方式调用目标资源，该目标资源用于第一节点的子IAB节点或UE与第一节点之间的数据传输；
第一节点中的MT可以按照所述目标复用方式进行传输。例如，MT可以按照该目标复用方式与第一节点的父节点进行数据传输。
需要说明的是，上述第一指示信息可以是：DU的资源分配，或者MT的资源分配。如果为DU的资源分配，DU根据第一指示信息进行传输；如果是MT的资源分配，DU在不影响MT传输的情况下进行传输。
应理解，在本申请实施例中，传输可以理解为发送或接收。
需要说明的是，在本申请实施例中，上述传输或者调度可以为周期性的，也可以为非周期性的，例如，在一些实施例中，所述按照所述目标复用方式进行调度或者传输包括以下至少一项：
按照所述目标复用方式进行周期性传输或者调度；
在预设时间段内，按照所述目标复用方式进行传输或者调度。
本申请实施例中，在预设时间段内，也可以进行周期性传输或调度，也可以仅进行一次传输或调度在此不做进一步的限定。
在一些实施例中，上述第一指示信息中可以携带相关参数，以指示目标复用方式的生效时间窗。例如：如果生效时间为周期配置的，在周期1中，可以使能复用方式1，在周期2中可以使能复用方式2。或者是，复用方式自身携带周期值，可以改变复用方式的周期，也就是指示下一次复用传输对应的复用方式的生效时间窗。
可选地，在一些实施例中，上述接收第二节点发送的第一指示信息的步骤之后，所述方法还包括：
在未接收到所述第一指示信息的情况下，按照默认的复用方式进行传输或者调度。
应理解，在本申请实施例中，接收第二节点发送的指示信息为第一节点的接收行为，具体地，第一节点可以具有接收的行为动作，但是实际可能无法接收到，例如，第二节点由于网络情况放弃发送第一指示信息等，此时，可以基于默认的复用方式进行传输或者调度。
可选地，未接收到可以理解为没有接收到第一指示信息，或者接收到第一指示信息没有成功解调获得目标复用方式。
其中，默认的复用方式可以通过预先协议约定、预配置和配置中的至少一项确定的默认复用方式。例如，可以直接协议约定、预配置、配置中的一种复用方式为默认的复用方式，可以协议约定多种复用方式，然后通过预配置或配置其中的某一种方式为默认的复用方式。当然在其他实施例中，还可以采用其他的方式，在此不再一一赘述。
可选地，在所述第一节点接收所述第一指示信息的情况下，所述第一指示信息承载于物理下行控制信道(Physical downlink control channel，PDCCH)、下行控制信息DCI、媒体接入控制单元(Medium Access Control Control Element，MAC CE)、无线资源控制(Radio Resource control,RRC)、终端辅助信息(UE assistance information)中或者回传接入协议(backhaul access protocal，BAP)控制(contorl)协议数据单元(Protocol Data Unit，PDU)上。
可选地，在一些实施例中，所述第一指示信息包括与所述目标复用方式关联的目标参数，所述目标参数包括以下任一项：PDCCH的码点、物理上行控制信道(Physical Uplink Control Channel，PUCCH)的序列、PUCCH的循环偏移、PUCCH解调参考信号(Demodulation Reference Signal，DMRS)的序列、PUCCH解调参考信号DMRS的循环偏移和PUCCH解调参考信号DMRS的跳频。
本申请实施例中，可以按照协议预定义、预配置和配置中至少一种方式设置目标参数与复用方式的映射关系，然后通过在第一指示信息中携带目标参数，从而可以根据目标参数与复用方式的映射关系确定第一指示信息所指示目标复用方式。其中，预配置和配置可以由宿主节点的CU执行，也可以由IAB父节点执行，在此不做进一步的限定。
针对上述PDCCH的码点可以理解为携带的PDCCH上显示指示的比特值，例如可以通过N比特表示该码点，该码点与复用方式关联，例如，码点1与复用方式1关联，码点2与复用方式2关联。换句话说，该PDCCH的码点也可以理解为复用方式的标识值，例如，采用码点1表示复用方式1，码点2表示复用方式2。
应理解是，上述可以协议预定义、预配置或配置目标复用方式的资源配置，在一些实施例中，所述目标复用方式的资源配置包括以下至少一项：时域位置、周期指示、时域资源指示、频域资源指示、空域资源指示、传输的流数指示、波束指示(beam index)、传输配置指示、功率指示、干扰指示以及调制和编码方案(Modulation and coding scheme，MCS)指示。
针对上述时域位置包括偏移值等，例如：PDCCH中携带复用方式，预定义PDCCH与复用方式之间的时间间隔为a。若IAB节点在slot n收到PDCCH携带的调度计划，则IAB节点在slot(n+a)采用所述复用方式进行调度或传输。应理解，资源配置具体的时间粒度可以为时隙、符号、子帧或毫秒等，以上仅一时隙为例进行说明。其中，a为大于等于0的值，也可以为小数。可选地，a的值与子载波间隔相关。
针对上述空域资源指示可以为波束索引(beam index)。
针对上述功率指示具体可以用于指示功率大小或者功率占比等。
针对上述MCS指示具体可以用于指示MCS的值或MCS的范围。
针对上述干扰指示可以理解为：允许或者不允许干扰的指标信息，例如，当在不满足干扰条件时，可以按照目标复用方式进行传输或调度。
需要说明的，上述所述资源配置的生效方式可以为周期生效或者事件触发生效。
例如，在一些实施例中，若为周期性触发，则根据配置的周期在对应的时域资源上使能目标复用方式。可选地，若周期为0，则生效一次。
若为事件触发，当满足预定义/预配置/配置的生效条件时，则使能对应的复用方式；若不满足预定义/预定义/配置的复用方式的生效条件，则不改变当前的复用方式，或者，采用默认的复用方式。
可选地，在一些实施例中，所述接收第二节点发送的第一指示信息的步骤之后，所述方法还包括：
在所述第一节点不支持所述目标复用方式的情况下，向所述第二节点发送第二指示信息，所述第二指示信息用于指示终止所述目标复用方式。
当然在其他实施例中，还可以由IAB父节点对目标复用方式信息终止，例如，在一些实施例中，假设如已经配置了第一节点的复用方式，但是由于 上下跳(即第一节点与子IAB节点或UE或者IAB父节点)的无线环境变化，导致原有的复用方式不合适时，具体包括以下行为：
第一节点可以向其IAB父节点发送终止上下跳复用调度的指示；IAB父节点收到终止指示后，不使用子IAB-DU的hard资源；
IAB父节点可以向其子IAB节点发送终止上下跳复用调度的指示；子IAB节点收到终止指示后，其DU调度子IAB-MT或UE时，不影响其MT的收发行为。
可选地，所述第一指示信息和所述第二指示信息均包括以下至少一项：周期指示、时间偏移、时域资源指示、频域资源指示、资源配置的类型指示、传输的流数指示、波束指示、功率指示、干扰指示以及调制和编码方案MCS指示。
本申请实施例中，第一指示信息和第二指示信息包括的内容可以相同也可以不同，在此不做进一步的限定。上述资源配置的类型具体可以为包括以下至少一项：
第一类型，该第一类型可以理解为包括UL、DL和Flexbile其中至少之一；
第二类型，该第一类型可以理解为包括Hard、Soft和Not available其中至少之一。
可选地，在一些实施例中，所述方法还包括：
向所述第二节点发送第三指示信息，所述第三指示信息用于指示推荐复用方式，所述推荐复用方式用于确定所述目标复用方式。
本申请实施例中，上述第三指示信息可以承载在PUCCH、上行控制信息(Uplink Control Information，UCI)或MAC CE上。由于通过第一节点向第二节点上报推荐复用方式，从而可以保证目标复用方式可以很好的适用于第一节点，进而提高复用传输的可靠性。
可选地，所述第三指示信息包括以下至少一项：物理上行控制信道PUCCH的序列、PUCCH的循环偏移、PUCCH解调参考信号DMRS的序列、PUCCH解调参考信号DMRS的循环偏移、PUCCH解调参考信号DMRS的跳频和PUCCH的码点。
应理解，在上述第二节点不支持所述推荐复用方式的情况下，所述目标复用方式为默认的复用方式。
本申请实施例中，由于第一节点基于上下跳网络的情况确定推荐的复用方式，然而，第二节点可能节点需要服务多个IAB子节点，存在冲突；或者，第二父节点的父节点在调度第二节点的MT的传输，与第二节点的DU的调度存在冲突，此时则第二节点无法支持第一节点的目标复用方式，第二节点可以向第一节点指示默认的复用方式，从而保证复用传输的可靠性。
应理解，第一节点可以周期性或者通过条件触发上报第三指示信息，也就是说，在一些实施例中，上述向所述第二节点发送第三指示信息包括以下至少一项：
按照第一预设周期向所述第二节点周期发送第三指示信息；
在满足预设的上报条件的情况下，向所述第二节点发送第三指示信息；
其中，所述上报条件为预定义、预配置或配置的触发条件。
上述第一预设周期可以由协议预定义、预配置或配置确定，在此不做进一步的限定。
需要说明的是，所述目标复用方式关联的指示粒度包括以下至少一项：M个时间单元和N个频域单元；
其中，M和N均为正整数，所述时间单元为子帧、时隙、符号或周期，所述频域粒度包括物理资源块(Physical Resource Block，PRB)、子带、预编码资源块组(Precoding Resource block Group，PRG)、子载波或资源单元(Resource element，RE)。
与此同时，上述推荐复用方式关联的指示粒度也可以包括以下至少一项：M1个时间单元和N1个频域单元；
其中，M1和N1均为正整数，所述时间单元为子帧、时隙、符号或周期，所述频域粒度包括物理资源块PRB、子带、预编码资源块组PRG、子载波或资源单元RE。
可选地，在一些实施例中，所述接收第二节点发送的第一指示信息包括按照第二预设周期接收所述第二节点发送的所述第一指示信息。
可选地，在一些实施例中，所述向第二节点发送第一指示信息包括按照 第三预设周期向所述第二节点发送所述第一指示信息。
本申请实施例中，通过周期性的发送或者接收第一指示信息，从而可以动态调整复用方式，提高第一节点中MT和DU复用的可靠性。
需要说明的是，在一些实施例中，还可以由终端向对应接入的IAB节点上报IAB节点的DU调度信息，该DU调度信息用于指示IAB节点的调度。然后该IAB节点，可以基于终端上报的DU调度信息进行传输或者调度，即IAB节点中的DU可以基于该DU调度信息进行资源调度实现与UE之间的传输。
进一步地，在本申请实施例中，当由第一节点发送第一指示信息到第二节点，以通知第二节点该第一节点的复用方式时，上述第一指示信息可以包括以下任一项物理上行控制信道PUCCH的序列、PUCCH的循环偏移、PUCCH解调参考信号DMRS的序列、PUCCH解调参考信号DMRS的循环偏移、PUCCH解调参考信号DMRS的跳频和PUCCH的码点。
针对上述PUCCH的序列，可以采用序列1表示复用方式1，序列2表示复用方式2。例如，第一节点可以根据可以支持的复用方式找到对应的PUCCH的序列，将对应序列的PUCCH上报给IAB父节点，IAB父节点根据接收到PUCCH序列，以及序列和复用方式的对应关系确定目标复用方式。
针对上述PUCCH的码点可以理解为PUCCH中显示携带N bit信息指示复用方式。协议预定义/预配置/配置各复用方式与码点的映射关系，副IAB节点可以根据接收到PUCCH的码点确定第一节点指示的目标复用方式。其中，预配置/配置可以为宿主节点CU或者IAB父节点配置。例如，第一节点根据可接受的复用方式及映射关系找到对应的码点，将对应码点发送给IAB父节点，IAB父节点根据接收的码点，以及码点和复用方式的映射关系，得到对应的复用方式。
上述UCI可以通过PUCCH传输，也可以复用在PUSCH上，在此不做进一步的限定。
为了更好的理解本申请的实现，以下通过一些实例对本申请的实现过程进行详细说明。
实施例一，具体包括以下流程：
1、预定义复用方式与PUCCH承载的信息的码点的映射关系，
2、IAB节点根据预定义/(预)配置的方式，周期/基于事件触发上报可接受的复用方式列表，该复用方式列表包括一个或者多个复用方式。其中，IAB节点在MAC CE/PUCCH中携带所述复用方式列表。或者通过UE assitance information上报所述复用方式列表。
3、IAB节点根据支持的复用方式列表，以及复用方式与PUCCH承载信息的码点的映射关系，发送PUCCH给IAB父节点/宿主节点。
4、IAB父节点/宿主节点根据接收的PUCCH的信息，以及复用方式与PUCCH承载的信息的码点的映射关系，获取对应的复用方式列表。IAB父节点决定复用方式，在PDCCH中携带复用方式指示。
5、IAB节点在时隙n接收PDCCH信令，获取复用方式信息，以及复用方式的生效时间窗口。IAB在时隙n+a采用所述复用方式传输资源。
实施例二，具体包括以下流程：
1、IAB父节点/宿主节点配置调度计划为周期上报，并配置调度计划的发送周期。
2、IAB节点在配置的上报周期的资源中，通过MAC CE上报调度计划列表给IAB父节点。
3、IAB父节点确定调度计划，在PDCCH中携带调度计划。调度计划包括其生效的时间窗口。
4、IAB节点根据PDCCH中指示的调度计划，在调度计划的生效窗口中根据指示的调度计划进行调度。
应理解，在本实施例中，IAB节点周期上报调度计划，IAB节点动态指示调度计划。
