通常，把提供无线回程链路资源的节点，如110，称为中继节点120的上级节点，而120则称为中继节点110下级节点。通常，下级节点可以被看作是上级节点的一个终端。应理解，图1所示的一体化接入和回程系统中，一个中继节点连接一个上级节点，但是在未来的中继系统中，为了提高无线回程链路的可靠性，一个中继节点，如120，可以有多个上级节点同时为其提供服务，如图中的rTRP 130还可以通过回程链路134连接到中继节点rTRP 120，即，rTRP 110和rTRP 120都为rTRP 130的上级节点。在本申请中，所述终端101,111,121,131，可以是静止或移动设备。例如移动设备可以是移动电话，智能终 端，平板电脑，笔记本电脑，视频游戏控制台，多媒体播放器，甚至是移动的中继节点等。静止设备通常位于固定位置，如计算机，接入点(通过无线链路连接到网络，如静止的中继节点)等。中继节点rTRP 110,120，130的名称并不限制其所部署的场景或网络，可以是比如relay，RN等任何其他名称。本申请使用rTRP仅是方便描述的需要。
在图1中，无线链路102,112,122,132,113,123，133,134可以是双向链路，包括上行和下行传输链路，特别地，无线回程链路113,123，133,134可以用于上级节点为下级节点提供服务，如上级节点100为下级节点110提供无线回程服务。应理解，回程链路的上行和下行可以是分离的，即，上行链路和下行链路不是通过同一个节点进行传输的。所述下行传输是指上级节点，如节点100，向下级节点，如节点110,传输信息或数据，上行传输是指下级节点，如节点110，向上级节点，如节点100，传输信息或数据。所述节点不限于是网络节点还是终端，例如，在D2D场景下，终端可以充当中继节点为其他终端服务。无线回程链路在某些场景下又可以是接入链路，如回程链路123对节点110来说也可以被视作接入链路，回程链路113也是节点100的接入链路。应理解，上述上级节点可以是基站，也可以是中继节点，下级节点可以是中继节点，也可以是具有中继功能的终端，如D2D场景下，下级节点也可以是终端。
图1中，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一个锚点基站，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。
为描述方便，以下将中继节点称为第一节点，第一节点的上级节点称为第二节点。第一节点和第二节点可以为基站，中继节点，具有中继功能的终端，或者任何具有中继功能的设备。
当中继节点在半双工约束下，带内中继的无线回程链路与接入链路的频谱资源重合，即，带内中继的回传链路与接入链路具有相同频段。如，rTRP在基站的下行无线回程链路进行接收时，就不能向下属终端或设备进行传输；而rTRP在回程链路上向上级节点进行上行传输时，不能接收下属终端或设备在上行接入链路或下级节点的回程链路上的传输。应理解，带内中继的半双工约束指的是同时同频收发的半双工约束，与系统本身采用的时分双工(time division duplexing,TDD)或频分双工方式(frequency division duplexing,FDD)无关。
下面对一些常用的技术术语给出如下定义：
接入链路：接入链路是指某个节点和它的下级节点进行通信时所使用的无线链路，包括上行传输和下行传输的链路。接入链路上的上行传输也被称为接入链路的上行传输，下行传输也被称为接入链路的下行传输。其中的节点包括但不限于前述IAB节点。
回传链路：回传链路是指某个节点和它的上级节点进行通信时所使用的无线链路，包括上行传输和下行传输的链路。回传链路上的上行传输也被称为回传链路的上行传输，下行传输也被称为回传链路的下行传输。其中的节点包括但不限于前述IAB节点。
对于波束(beam)，可以理解为空间资源，可以指具有能量传输指向性的发送或接收预编码向量。并且，该发送或接收预编码向量能够通过索引信息进行标识。其中，能量传输指向性可以指通过该预编码向量对所需发送的信号进行预编码处理，经过该预编码处理的信号具有一定的空间指向性，接收经过该预编码向量进行预编码处理后的信号具有较好 的接收功率，如满足接收解调信噪比等；所述能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。可选地，同一通信设备，比如终端设备或网络设备，可以有不同的预编码向量，不同的通信设备也可以有不同的预编码向量，即对应不同的波束。
针对通信设备的配置或者能力，一个通信设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个波束或者多个波束。波束信息可以通过索引信息进行标识，可选地，所述索引信息可以对应配置终端设备的资源标识(identity，ID)。例如，所述索引信息可以对应配置的信道状态信息参考信号(channel status information reference signal,CSI-RS)的ID或者索引(index)或资源，也可以是对应配置的上行探测参考信号(sounding reference signal,SRS)的ID或者资源。或者，可选地，所述索引信息也可以是通过波束承载的信号或信道显示或隐式承载的索引信息，比如，所述索引信息包括但是不限于通过波束发送的同步信号或者广播信道指示该波束的索引信息。该资源可以是以下至少一种：时域、频域、码域(序列)。
应当理解，本文中使用的术语“和/或”仅仅是一种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。
另外，由于5G NR支持高频段，并且采用了大规模天线技术(Massive MIMO)，使得信号的能量可以集中的向某个方向传输，这样使得IAB设备可以同时接收多个方向传输过来的信号，下面再介绍IAB中空分传输中的一些系统组成示意图，如图2-图5所示。
图2-图5所示，IAB系统包括：IAB设备，例如：IAB node 0，IAB node1，IAB node2，以及各IAB设备所服务的终端设备UE。图2中，IAB node 1同时接收来自UE的上行信号和来自IAB node 2的上行信号。图3中，IAB node 1所服务的UE，和相邻的节点IAB node 2同时发送上行信号，IAB node 1同时接收来自UE的上行信号和来自IAB node0以及IAB node 2的上行信号。图4中，IAB node 1所服务的UE和IAB node 2同时发送上行信号，IAB node 1同时接收来自UE的上行信号和来自IAB node 2的上行信号。图5中，IAB node 2在一个时间点或者时间段内，IAB node 2向UE发送下行信号，同时向IAB node 1发送上行信号。
图6为本申请实施例提供的一种功率控制的方法流程图，如图6所示，本实施例的方法包括：
以下以IAB中的中继节点以IAB节点为例，以图3所示的IAB系统架构为例对功率控制的方法进行描述，其中，为了便于描述，以IAB Node1作为第一节点，第一节点的上级节点为第二节点，例如IAB Node0，也可以称为第一节点的上游节点为IAB Node0，第一节点的下级节点或者下游节点为IAB Node2。第一节点，第二节点以及第三节点可以为基站，中继节点，具有中继功能的终端，或者任何具有中继功能的设备。IAB node 1在一个时间点或者时间段内，IAB node 1同时接收来自IAB node0以及IAB node2的信号，或者IAB node 1同时向IAB node0以及IAB node2的发送信号。
S600、第二节点生成传输配置消息，所述传输配置消息包括：传输配置索引信息以及与所述配传输配置索引信息对应的传输参数，其中，所述传输配置索引信息用于标识不同的传输模式。
其中，所述传输参数包括以下至少一种或多种：定时调整信息，DMRS端口信息，功 率控制参数，时间资源信息，时隙方向信息，接收波束信息，发送波束信息，子载波间隔，有效时间。
所述传输模式包括：空分复用传输和/或非空分复用传输。
所述定时调整信息用于调整所述第一节点的发送时间或者第一节点的接收时间，所述定时调整信息是所述第一节点计算获得。
传输配置索引信息包括：部分带宽标识BWP ID。
所述传输配置消息消息可以承载在无线资源控制(radio resource control,RRC)协议消息中，或者，通过F1接口承载在基于F1-AP(F1-application protocol)协议的消息中，例如：下行无线资源控制转移消息(DL RRC TRANSFER message)，所述F1接口为IAB节点2的分布单元(distributed unit,DU)与Donor节点的集中单元(central unit,CU)之间的F1接口，或者承载在下行控制信息(downlink control information,DCI)消息或MAC CE(media access control control element)中。
所述参考信号配置消息还可以是由Donor节点通过RRC、DCI或MAC CE发送给IAB节点2的MT，再由IAB节点2的MT通过内部的信令交互通知IAB节点2的DU。
由于不同的传输模式，各节点需要配置的传输参数不同，通过标识不同的传输模式传输配置索引信息将不同传输模式下的各个传输参数进行组合，传输时可以通过配置传输模式传输配置索引信息便可以获知对应的各个传输参数集合，不仅减小了传输时的大量参数的导致的信令开销，同时通过底层信令例如DCI，极大降低了传输时延，提高了传输性能，进而可以快速的实现再各种传输模式下的切换。
上述所述传输参数中包括定时调整信息，由于不同的传输模式下，定时调整信息的值不同，下面针对空分复用的传输模式和非空分复用的传输模式，所述节点获取的定时调整信息的方法进行介绍。
如图7和图3所示，所述方法如下：
图7为传输模式是非空分复用，IAB node DU的下行发送时间和上级节点Parent node DU Tx timing对齐(图中第一行和第四行的定时对齐)，这是因为在TDD系统中，小区间的下行定时一般是同步对齐的，否则会造成比较严重的小区间交叉链路干扰，对性能十分不利。协议规定了基站的上行接收(图中第二行)与下行发送(图中第一行)之间会有一个TA offset。IAB node作为下级节点，发送上行的时间(图中第三行)与上级节点的上行接收会有一个传输时延(节点间距离除以光速)
图8为传输模式是空分复用，在这种传输模式下，以图3的网络架构为例，各IAB node包括第一功能实体MT和第二功能实体DU，所述MT和DU可以集成，也可以独立运行。在常规接收IAB node 0的回传下行数据时和开启空分接收时，需要应用不同的传输参数。
在空分复用下，IAB node的上行发送信号(图中第三行)的发送定时即图7中的IABnode MT Tx timing与IAB node的下行发送(图中第四行)信号的发送定时即图7中的IABnode DU Tx timing对齐，即IAB node的MT上行发送定时要与IAB node的DU下行发送定时对齐。
若上级节点的接收定时不考虑，对比图7和图8可以可知，为了在空分复用下，实现IAB node的空分发送，需要对IAB节点的上行发送定时进行调整，具体为将第一节点的上行发送即将IAB node MT Tx timing推迟一个定时调整量TA，例如为Tp+TA_offset，具体的TA调整量可以通过测量得到，一般有如下两种方式：
方法1：结合图3，首先IAB node DU发送下行参考信号，上级节点(Parent node)IAB node0的DU进行接收或者donor节点对下行参考信号进行测量，获得IAB node DU的发送信号的发送定时。
其次，所述IAB node0的DU可以得到下级节点按照下行定时发送(图2第四行)信号时，到达上级节点的时间。
对比没有开启空分时，下级节点的上行发送到达上级节点的时间(图1第二行)，上级节点可以得到一个定时调整量。
然后，根据IAB node DU下行发送定时(IAB node DU Tx timing)和IAB node的MT上行发送定时(IAB node MT Tx timing)，获得IAB的定时调整量。
最后，将IAB node MT的发送定时根据获得的定时调整量进行调整，使得IAB node MT Tx timing与IAB DU Tx timing对齐，即图8的第三行和第四行。具体可以将IAB node MT Tx timing延迟一个定时调整量，使得与IAB DU Tx timing对齐
通过类型的方法，也可以得到，通过调整IAB DU的发送定时，例如通过提前获得定时调整量，使得IAB DU的发送定时与IAB MT的发送定时对齐。
总之，所述定时调整配置可以含一个定时调整值，所述定时调整值可以通过测量得到。具体的，上级节点或宿主节点配置IAB节点发送下行参考信号。上级节点测量IAB节点(或IAB DU)发送的参考信号。上级节点根据测量结果，比较上级节点与下级节点之间回传链路的上行接收达到时间，可以确定一个定时差值。上级节点将定时差值，确定为定时调整量。
所述参考信号可以是同步信号(同步信号包括主同步信号PSS和辅同步信号SSS)，也可以是CSI-RS(信道状态信息参考信号)，还可以是DM-RS(解调参考信号)，还可以是跟踪参考信号(tracking reference signal,TRS)。本专利不做限定。
方法2：由于空分开启时，通过IAB node1的自身去获取定时调整差值，不通过Donor节点测量获得，进而实现IAB node1的上行发送定时与下行发送定时对齐。
综上，对于定时调整信息，具体为定时调整量TA具体可以为以下两种配置方法：
1)Donor或上级节点提前配置多种定时调整配置，每个调整配置对应一个index ID。这种情况下在该传输模式的配置中也可以配置定时调整配置索引Index或者标识ID用于标识定时调整定时调整量。
2)非空分复用的配置中定时调整配置是固定配置的。
通过上述的两种方式可知，在空分复用的传输模式下获得的定时调整量TA是不同。因此，针对不同的传输模式，定时调整信息包括定时调整量TA是不同，需根据不同过的传输模式，设置不同传输参数集合是很有必要的。
上面只是给出了两种可能的定时调整确定的方法，但是我们并不限定一定是这两种方法。对于空分接收的情况，IAB node DU的接收定时(即IAB node在自身接入链路上的上行接收定时)需要和IAB node MT的接收定时(即IAB node在回传链路上的下行接收定时)对齐。此时IAB node可以发送一个定时调整命令给自己的下级节点，来调整下级节点的上行发送定时。该定时调整命令可以推迟下级节点的上行发送，或者可以调整下级节点的上行发送，完成符号级对齐。
进一步地，所述传输参数还可以包含一个“有效时间”的信息，用于标识该传输参数集合的生效时间或者持续时间。比如，可以是一个flag，用于指示该参数有效时间是接下来， 或者是稍后某一个或多个时隙有效，或者仅有效于当前调度的时隙。
或者另一种可能是，该传输参数是周期性有效，则需要包含具体的周期和偏移(period and offset)，用于确定具体周期长度，以及在每个周期/帧中的时间位置。
可选的，协议定义一个初始的或默认的传输参数配置，该配置可以某个index，或者一套额外的，通过高层信令下发的配置。
S602、所述第二节点发送所述传输配置消息给所述第一节点。
S604、第一节点接收传输配置消息。
S606、所述第二节点发送传输指示消息，所述传输指示消息包括：所述传输配置索引信息，其中，所述传输指示消息用于指示所述第一节点应用所述传输配置索引信息对应的传输参数；
所述传输指示消息承载在下行控制信息DCI或者媒体接入控制控制元素MAC CE上进行发送。
S608、所述第一节点获得传输指示消息。
上述步骤S606可选，若第一节点自身获得传输指示消息时，则不需要S606，若S606中由第一节点的上级节点或者donor生成并下发，则S606保留。
S610、所述第一节点根据所述传输指示消息中的传输配置索引信息，通过所述传输配置索引信息对应的传输参数进行数据传输。
为方便理解，下面提供实施例一的传输配置索引信息的消息格式一种示例(以下按照TS 38.331的信元格式举例，但是本方案并不限于以下的形式。格式，信元名称，每个配置所在的信元层级等等都有可能不同)。
如果IAB节点在中收到了以下配置信息(RRC消息)，在步骤2中，上级节点通过在DCI或MAC CE中包含TransmissionMode-Id，就能快速配置/修改IAB节点的传输参数。–TransmissionMode-Id

本申请实施例提供的一种传输参数的配置方法，由于不同的传输模式，各节点需要配置的传输参数不同，通过标识不同的传输模式传输配置索引信息将不同传输模式下的各个传输参数进行组合，传输时可以通过配置传输模式传输配置索引信息便可以获知对应的各个传输参数集合，不仅减小了传输时的大量参数的导致的信令开销，同时通过底层信令例如DCI，极大降低了传输时延，提高了传输性能，进而可以快速的实现再各种传输模式下的切换。
与上述实施例不同另外一种实现方式可以如下：
上述实施例是传输配置索引信息的消息格式都是新增消息的类型或者新定义的消息格式，这里也可以通过现有的消息例如部分带宽标识BWP ID的扩展来实现，具体为在BWP配置中新增例如传输配置索引信息，例如用BWP ID来标识传输配置索引信息。现有协议中，BWP的配置方法类似于实施例一，是通过RRC配置，通过DCI切换BWP。因为总共4个BWP，DCI中占用两个bit，用于指示具体4个BWP中的某一个。
本质上就是把实施例一中例举的那些参数，添加到关键术语定义中的BWP配置里面。
下面是BWP的配置格式：
BWP是一种UE特定的配置(UE-specific)，即是对于每一个UE，基站单独配置、调度实现的。BWP不是小区固定的。BWP与载波聚合(carrier aggregation,CA)的区别是：一个载波上，基站可以配置4个上行和或下行BWP，一个UE在一个时刻只能有一个激活的BWP。
每个BWP可以支持配置部分或完整的上下行物理资源

Figure PCTCN2019108994-appb-000005
Figure PCTCN2019108994-appb-000006
在BWP的配置中，类似于实施例一的方案，增加定时调整参数，具体有两种实现方式:
Donor或上级节点提前配置多种定时调整配置，每个调整配置对应一个index ID。这种情况下BWP配置中会出现定时调整配置的ID
BWP配置中直接出现具体的定时调整配置
通过DCI的BWP switch，就能针对空分复用等特殊传输模式，快速调整定时的相关参数。
在BWP配置中，包括半静态预留空白DMRS端口的配置，或包括对BH链路可能使用的DMRS端口集合的限制。根据BWP配置中的DMRS端口配置，下级IAB节点为其接入链路分配DMRS
由于BWP的有效时间是基于bwp-Inactivity Timer，从2ms到2560ms不等。空分传输可能有效时间更短，如一、两个时隙。所以如果通过BWP切换，激活空分传输，可选的，需要包含传输参数的有效时间信息。
同实施例一：
比如，可以是一个flag，用于指示该参数有效时间是接下来，或者是稍后某一个或多个时隙有效，或者仅有效于当前调度的时隙。
或者另一种可能是，该传输参数是在该BWP配置中周期性有效，则需要包含具体的周期和偏移(period and offset)，用于确定具体周期长度，以及在每个周期/帧中的时间位置。
本方案同实施例一，可以扩展通过BWP配置IAB空分相关的其他参数：
可以在BWP配置中包含一个当前BWP的SDM时间资源指示，具体一个帧中某些时隙符号允许空分传输。
可以在BWP配置中包含指示，用于指示部分灵活时隙的方向。(现有技术中，基站 会配置小区所有的时隙方向，为上行、下行或者Flexible，即灵活时隙。灵活时隙的方向在动态调度中通过SFI slot format indication来指示具体的方向)在空分复用中，基站可以通过确定本次空分传输的时隙方向，来降低可能出现的干扰。
可以BWP配置中包含一个默认的发送波束指示，用于切换BWP开启某种空分模式之后，同时切换接收和或发送波束，抑制潜在的干扰。
通过将传输的参数引入BWP的配置中，让某个BWP配置，变成了特殊传输模式下使用的BWP。使得上级节点可以利用BWP switch的命令，切换下级节点的激活BWP(active BWP)，达到应用/激活某些传输参数的目的。与实施例一相比，实施例二的方案不需要引入额外的DCI(物理层信令)，复用了现有的BWP switch机制。与现有技术相比，只是在BWP的RRC配置中，包含了新的信息，用于确定特定传输模式下的参数(即实施例一是新增了配置和信令，实施例二不用增加新的空口信令)
