背景技术
目前，在新空口(New Radio，NR)系统中，可以通过转发节点转发接入网设备和终端之间的信息，以使得接入网设备可以和终端进行通信，从而可以扩展接入网设备的覆盖范围。通常，转发节点在转发接入网设备和终端之间的信息时，需要对转发节点和终端之间的下行波束和上行波束分别进行波束训练，以确定在转发节点和终端之间的下行信道和上行信道的传输参数，从而转发节点可以按照下行信道和上行信道的传输参数，转发接入网设备和终端之间的信息。
但是，由于转发节点要对转发节点和终端之间的下行波束和上行波束分别进行波束训练，因此，可能会导致转发节点的资源和时间的消耗较高，从而导致用于信息传输的资源减少、且传输的时延增加。如此，导致转发节点的转发性能的降低。

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所获得的所有其他实施例，都属于本申请保护的范围。
以下将对本申请实施例涉及的术语进行说明。
1、层(Layer，L)1转发节点
通常，L1转发节点可以包括可重构智能表面(Reconfigurable Intelligent Surface，RIS)节点和基站控制放大器(Network Controlled Repeater，NCR)节点，该RIS节点和NCR节点可以在接入网设备的控制下，扩展小区的覆盖。
(1)RIS节点
RIS节点可以包括一个RIS-终端(Mobile Termination，MT)功能单元和一个RIS-反射面单元(Reflection Surface Unit，RSU)，其中，如图1所示，RIS-MT功能单元用于RIS节点与接入网设备之间建立无线连接、RIS节点向接入网设备发送RIS节点的测量汇报以及接入网设备对RIS节点的反射控制信令等，RIS-RSU用于在接入网设备和终端之间进行信号的反射传递，包括同步信号块(Synchronization Signal Block，SSB)、系统消息、上下行专有信令、上下行控制信道以及上下行数据信道等。
其中，RIS-MT功能单元可能使用独立的天线，也可以共用RIS-RSU上的天线(或无线信号接收介质)。
其中，在RIS-MT功能单元和RIS-RSU之间有RIS-RSU控制单元(例如天线面板控制单元(panel controller))，从而RIS-MT功能单元可以从接入网设备接收用于控制RIS-RSU控制单元的信令，并将该信令发送给RIS-RSU控制单元，以使得RIS-RSU控制单元可以调整RIS-RSU单元的反射阵列的相位幅度矩阵，以调整RIS-RSU的发射参数(例如反射波束参数等。
(2)NCR节点
基站控制放大器(Network Controlled Repeater，NCR)节点，又称作智能放大器(Smart Repeater)，可以接收和放大来自接入网设备的下行信号，以使得到达终端的下行信号强度增加；或者，可以放大来自终端的上行信号，以使得达到接入网设备的上行信号强度增加。如图2所示，NCR节点可以包括一个NCR-MT功能单元、一个NCR-射频模块(Radio Unit，RU)，其中，NCR-MT可以与接入网设备之间建立连接，从而接入网设备可以通过NCR-MT与NCR节点的信号放大器交互控制信令，以指示该信号放大器的NCR-MT(或NCR-RU)的发送或接收相关参数等，以提高NCR节点的工作效率和降低干扰，NCR-RU用于转发接入网设备和终端之间的无线信号，以增加所述无线信号的强度。
2、L1转发节点的接入链路(Access Link)的信道关联性(互易性)
Access Link的信道关联性，可以被称作Access Link的上下行信道之间的互易性(Reciprocity)，又可以被称作Access Link的上下行信道之间的关联性(Correspondence)，其本质是同一Access Link的上行信道的特性之间是相似的，即上下行信道的收发波束方向、收发波束宽度、收发波束增益、信道的秩、多径特性、波束赋形参数等是相似的，因此，可以根据同一Access Link的一个传输方向(例如上行或下行)的信道的传输参数，确定同一Access Link的另一个传输方向(例如下行或上行)的信道的传输参数。
如图3所示，NCR节点和终端之间的Access Link的上行信道(上行转发)Uplink和下行信道(下行转发)Downlink之间是存在互易性的，因此，可以根据Uplink的传输参数，确定Downlink的传输参数，或者，可以根据Downlink的传输参数，确定Uplink的传输参数。
3、其他术语
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术语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。

下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的传输参数确定方 法、装置、网络侧设备及介质进行详细地说明。
在相关技术中，转发节点在转发接入网设备和终端之间的信息时，需要先对转发节点和终端之间的波束进行波束训练。
在一种场景下，转发节点需要对转发节点和终端之间的下行波束和上行波束分别进行波束训练，以确定在转发节点和终端之间的下行信道和上行信道的传输参数，从而转发节点可以按照下行信道和上行信道的传输参数，转发接入网设备和终端之间的信息。但是，由于转发节点要对转发节点和终端之间的下行波束和上行波束分别进行波束训练，因此，可能会导致转发节点的资源和时间的消耗较高，从而导致用于信息传输的资源减少、且传输的时延增加。
在另一种场景下，转发节点可以仅对转发节点和终端之间的一个上行波束(或一个下行波束)进行波束训练，并根据该一个上行波束(或一个下行波束)的传输参数，计算得到该一个下行波束(或该一个上行波束)的传输参数。但是，由于该转发节点可能没有足够的信息用于确定上下行链路之间的对应关系，这样可能导致转发节点无法根据该一个上行波束(或一个下行波束)的传输参数，计算得到该一个下行波束(或该一个上行波束)的传输参数，即转发节点还是需要对转发节点和终端之间的下行波束和上行波束分别进行波束训练，以确定在转发节点和终端之间的下行信道和上行信道的传输参数，因此，可能会导致转发节点的资源和时间的消耗较高，从而导致用于信息传输的资源减少、且传输的时延增加。
然而，本申请实施例中，转发节点可以根据接入网设备发送的辅助信息，确定与转发节点和终端之间的一个下行信道(或一个上行信道)关联的一个上行信道(或一个下行信道)，这样，转发节点可以直接根据该一个上行信道(或一个下行信道)的传输参数，确定该一个下行信道(或一个上行信道)的传输参数，而无需对转发节点和终端之间的下行波束和上行波束分别进行波束训练，因此，可以减少转发节点的资源和时间的消耗，从而可以提高用于信息传输的资源、且减少传输的时延。

又示例性地，假设第二传输信道为下行信道，第一传输信道为上行信道，则第二传输信道用于在转发节点与终端之间第2次转发无线信号，第一传输信道用于在转发节点与终端之间第3次转发无线信号，即可以根据前一次下行转发的传输参数，确定下一次上行转发的传输参数。

可选地，本申请实施例中，在转发节点确定第一传输信道的传输参数之后，转发节点可以按照该第一传输信道的传输参数，与终端在第一传输信道上进行信息传输。
本申请实施例提供的传输参数确定方法，转发节点可以先从第一网络侧设备接收用于指示第一传输信道相关的信息的辅助信息，再根据该辅助信息，确定与该第一传输信道关联的第二传输信道，从而转发节点可以根据该第二传输信道的传输参数，确定第一传输信道的传输参数；其中，该第一传输信道为：转发节点与终端之间转发无线信号的上行信道或下行信道，第二传输信道的传输方向和第一传输信道的传输方向不同。由于转发节点可以根据第一网络侧设备发送的辅助信息，确定与第一传输信道关联的第二传输信道，这样，转发节点可以直接根据该第二传输信道的传输参数，确定第一传输信道的传输参数，而无 需对转发节点和终端之间的下行波束和上行波束分别进行波束训练，以确定第一传输信道的传输参数，因此，可以减少转发节点的资源和时间的消耗，从而可以提高用于信息传输的资源、且减少传输的时延，如此，可以提高转发节点的转发性能。
下面将以第一网络侧设备向转发节点发送用于控制在第一传输信道上的信息传输的控制信息的同时，向转发节点发送该辅助信息为例，进行举例说明。

本申请实施例中，第一控制信息用于控制在第一传输信道上的信息传输。
下面将以不同的示例为例，举例说明转发节点是如何确定第二传输信道的。
可选地，本申请实施例中，结合图6，如图7所示，上述步骤103具体可以通过下述的步骤103a和步骤103b实现。
步骤103a、转发节点根据辅助信息，确定第一控制信息对应的第二控制信息。
本申请实施例中，上述第二控制信息用于控制在第二传输信道上的信息传输。
可选地，本申请实施例中，第二控制信息具体可以为侧边控制信息。
可选地，本申请实施例中，在转发节点中存储有至少一个历史控制信息，每个历史控制信息中包括一个目标信息，从而转发节点可以从至少一个目标信息中，确定与辅助信息相匹配(例如相同)的一个目标信息，并将该一个目标信息对应的历史控制信息，确定为第二控制信息。
其中，针对至少一个历史控制信息中的每个历史控制信息，一个历史控制信息中包括的一个目标信息用于指示该一个历史控制信息对应的传输信道相关的信息。
以下将以四种不同的示例为例，进行举例说明。
在一种示例中，上述辅助信息包括终端的第一设备标识；上述第二控制信息中包括的设备标识，与第一设备标识相匹配。
其中，第一设备标识具体可以为：用户设备身份标识号(User Equipment Identification，UE_ID)。
转发节点可以根据第一设备标识，从转发节点中存储的至少一个历史控制信息中包括的至少一个目标信息(即至少一个设备标识)中，确定出与第一设备标识相同的一个设备 标识，并将该一个设备标识对应的一个历史控制信息，确定为第二控制信息。

其中，在第一指示信息指示确定第二控制信息的确定方式为基于设备标识的确定方式的情况下，辅助信息包括第一设备标识，且至少一个历史控制信息中包括至少一个设备标识，从而转发节点可以根据第一设备标识，确定第一控制信息对应的第二控制信息。
其中，在第一指示信息指示确定第二控制信息的确定方式为基于RNTI的确定方式的情 况下，辅助信息包括第一RNTI，且至少一个历史控制信息中包括至少一个RNTI，从而转发节点可以根据第一RNTI，确定第一控制信息对应的第二控制信息。
其中，在第一指示信息指示确定第二控制信息的确定方式为基于链路标识的确定方式的情况下，辅助信息包括第一链路标识，且至少一个历史控制信息中包括至少一个链路标识，从而转发节点可以根据第一链路标识，确定第一控制信息对应的第二控制信息。
其中，在第一指示信息指示确定第二控制信息的确定方式为基于信道关联指示的确定方式，辅助信息包括第一信道关联指示，且至少一个历史控制信息中包括至少一个信道关联指示，从而转发节点可以根据第一信道关联指示，确定第一控制信息对应的第二控制信息。
如此可知，由于转发节点可以采用第一网络侧设备指示的确定第二控制信息的确定方式，根据辅助信息，确定第一控制信息对应的第二控制信息，而无需转发节点自身决定确定第二控制信息的确定方式，因此，可以提高确定的第二控制信息的准确性，从而可以提高确定第一传输信道的传输参数的准确性。
步骤103b、转发节点将第二控制信息对应的传输信道，确定为第二传输信道。
本申请实施例中，转发节点可以将第二控制信息控制转发节点进行信息传输的传输信道，确定为第二传输信道。
如此可知，由于转发节点可以根据辅助信息，准确地确定第一控制信息对应的第二控制信息，因此，可以提高确定第二传输信道的准确性，从而可以提高确定第一传输信道的传输参数的准确性。
下面将以具体的示例为例，举例说明本申请实施例的转发节点和第一网络侧设备之间的信令流程。
