具体实施方式
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说 明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
为了便于本领域技术人员理解，在此先对本申请实施例中涉及到的术语进行简要说明。
1、波束(beam)
波束是一种通信资源。波束可以是宽波束，或者窄波束，或者其他类型的波束。形成波束的技术可以是波束成形技术或者其他技术手段。波束成形技术具体可以为数字波束成形技术、模拟波束成形技术、混合数字/模拟波束成形技术。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。
可以将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道、控制信道、探测信号等。例如，发射波束是指无线信号经天线发射出去后在空间不同方向上的信号强度分布，接收波束是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。可以理解的是，一个波束包括的一个或多个天线端口可以看作是一个天线端口集。
在使用低频或中频频段时，可以全向发送信号或者通过一个较宽的角度发送信号。在使用高频频段时，由于高频频段的波长较短，使得天线尺寸较小，因此可以在发送端和接收端布置很多天线阵子以构成天线阵列。这样，发送端以一定波束赋形权值发送信号，使发送信号形成具有空间指向性的波束，接收端用天线阵列以一定波束赋形权值进行信号的接收，能够提高信号在接收端的接收功率，对抗路径损耗。
在新空口(new radio，NR)的协议中，波束的体现可以是空域滤波器(spatial domain filter)，空间滤波器(spatial filter)，空域参数(spatial domain parameter)，空间参数(spatial parameter)，空域设置(spatial domain setting)，空间设置(spatial setting)，QCL信息，QCL假设，QCL指示等。波束可以通过传输配置指示(transmission configuration indicator，TCI)状态(state)来指示。波束也可以通过空间关系(spatial relation)参数来指示。因此，本申请实施例中，波束可以替换为空域滤波器，空间滤波器，空域参数，空间参数，空域设置，空间设置，QCL信息，QCL假设，QCL指示，TCI state(包括DL TCI state和/或UL TCI state)，空间关系等。上述术语之间也可以相互等效。当然，波束也可以替换为其他表示波束的术语，本申请实施例不作限定。
2、QCL
QCL用于表示多个资源之间具有一个或多个相同或者类似的通信特征，对于具有QCL关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口具有QCL关系，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。信道大尺度特性可以包括：延迟扩展、平均延 迟、多普勒扩展、多普勒频移、平均增益、接收参数、终端设备接收波束编号、发射/接收信道相关性、接收到达角、接收机天线的空间相关性，主到达角(angel-of-arrival，AoA)、平均到达角、AoA的扩展等。
具体实现中，QCL用于指示至少两组天线端口是否具有同位关系为：QCL用于指示至少两组天线端口发送的信道状态信息参考信号是否来自相同的传输点，或QCL用于指示至少两组天线端口发送的信道状态信息参考信号是否来自相同的波束组。
3、准同位假设(QCL assumption)
准同位假设是指假设两个天线端口之间是否具有QCL关系。准同位假设的配置和指示可以用来帮助接收端进行信号的接收和解调。例如，如果接收端确认A端口和B端口具有QCL关系，则接收端可以将A端口上测得的信道大尺度特性参数用于B端口上的信号的测量和解调。
4、空域准同位(spatial QCL)
空域准同位是QCL的一种类型。空域的理解可以从两个角度：从发送端或者从接收端。从发送端来看，如果两个天线端口是空域准同位的，那么这两个天线端口的对应的波束方向在空间上是一致的。从接收端来看，如果两个天线端口是空域准同位的，那么接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
5、参考信号(reference signal，RS)
根据长期演进(long term evolution，LTE)/NR的协议，在物理层，上行通信包括上行物理信道和上行信号的传输。其中，上行物理信道包括：随机接入信道(randomaccess channel，PRACH)，上行控制信道(physical uplink control channel，PUCCH)，上行数据信道(physical uplink shared channel，PUSCH)等。上行信号包括：信道探测信号(sounding reference signal，SRS)，上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)，上行数据信道解调参考信号(PUSCH-DMRS)，上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)，上行定位信号(uplink positioning RS)等。
下行通信包括下行物理信道和下行信号的传输。其中，下行物理信道包括：广播信道(physical broadcast channel，PBCH)，下行控制信道(physical downlink control channel，PDCCH)，下行数据信道(physical downlink shared channel，PDSCH)等。下行信号包括：主同步信号(primary synchronization signal，PSS)/辅同步信号(secondary synchronization signal，SSS)，下行控制信道解调参考信号(PDCCH-DMRS)，下行数据信道解调参考信号(PDSCH-DMRS)，相位噪声跟踪信号(PTRS)，信道状态信息参考信号(channel status information reference signal，CSI-RS)，小区信号(cell reference signal，CRS)(NR中没有该信号)，精同步信号(time/frequency tracking referenee signal，TRS)(LTE中没有该信号)，LTE/NR定位信号(positioning referenee signal)等。
6、载波聚合(carrier aggregation，CA)
CA是LTE-Advanced中的关键技术。为了满足单用户峰值速率和系统容量提升的要求，一种最直接的办法就是增加系统传输带宽。CA技术可以将频域连续或者非连续的多个载波同时配置给一个终端设备使用，以增加终端设备的总带宽，从而实现增 加用户容量的效果。NR中也使用了CA技术。
7、TCI
TCI是下行控制信息(downlink control information，DCI)中用于指示PDSCH天线端口准共址的字段。TCI由无线资源控制(radio resource control，RRC)配置，在配置信令中称为传输配置指示状态(TCI-state)。TCI-state包括一个或两个QCL关系，QCL用于指示当前将要接收的信号，与之前已知的某参考信号之间的某种一致性关系。若存在QCL关系，则终端设备可以使用之前接收某参考信号时的接收参数，来接收将要到来的信号。
QCL类型包括A类型(type A)、B类型(type B)、C类型(type C)、D类型(type D)。QCL类型不同，根据参考信号获取的信息不同。常见的QCL的参考信号包括：RRC配置前，同步信号块(synchronization signal block，SSB)给PDSCH和PDCCH中的DMRS做参考；RRC配置后，sub6G下，SSB给TRS作参考，TRS给DMRS作参考，CSI-RS给DMRS作参考。
6GHz以上频段，会有type D的QCL类型。这时type A/B/C+type D(即配置两种，包含D和另外一种，D用于表示波束信息)，当前协议规定type A/B/C三种只能同时存在其中一种，其中type A包含了type B和type C的信息，所以同时配置type A和type B/C是没有意义的。同理，若同时配置type B和type C，则就等效于type A，直接配置type A即可。
8、天线面板
天线面板可以由一组或多组天线阵列组成，一组天线阵列包括一个或多个天线阵元。
需要说明的是，本申请实施例中涉及到的天线面板可以替换为天线阵列、天线单元、天线端口、天线组、天线等，本申请实施例不做限定。
目前，当终端设备支持多个频段通信的能力时，在终端设备与网络设备通信之前，可以在每个频段上进行波束扫描，以确定终端设备在每个频段上所使用的接收波束和发送波束。在没有任何先验信息(例如终端的架构假设)的情况下，网络设备指示的终端设备在一个频段上确定的波束以及传输参数，不能直接应用于终端设备其他频段的通信传输。由于在某频段上进行波束扫描的过程中终端设备与网络设备多次进行交互，因此终端在每个频段上均执行波束扫描，会导致增加通信开销，降低通信效率。
为了解决上述问题，本申请实施例提供一种传输参数确定方法及装置，终端设备获取配置信息和第一频段的指示信息，第一频段的指示信息用于指示第一频段的传输参数，配置信息用于指示第一频段的传输参数用于第一频段和第二频段。之后，终端设备根据配置信息和指示信息确定第二频段的传输参数。这样，在第一频段对应的第一天线面板和第二频段对应的第二天线面板具有相关关系时，终端设备能够直接根据第一频段的传输参数确定出第二频段的传输参数，无需在第二频段上进行扫描来获得第二频段的传输参数，降低了通信开销，提高了通信效率。
本申请实施例提供的传输参数确定方法适用于通信系统。图1示出了该通信系统的一种结构。如图1所示，该通信系统可以包括：网络设备11和终端设备12。网络设备11和终端设备12使用多个频段的通信资源进行通信，图1中以第一频段和第二 频段为例示出。
网络设备11，用于接收终端设备12发送的第一信息，该第一信息用于表征终端设备12中存在具有相关关系的第一频段对应的第一天线面板和第二频段对应的第二天线面板。网络设备11，还用于基于第一信息得到配置信息和第一频段的指示信息，并向终端设备12发送配置信息和指示信息。指示信息用于指示第一频段的传输参数，配置信息用于指示第一频段的传输参数用于第一频段和第二频段。
在一些实施例中，网络设备11，是部署在无线接入网中为终端设备12提供无线通信功能的设备。网络设备11可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等。在不同的无线接入技术的系统中，网络设备11的名称可能会有所不同。例如，全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中，网络设备11称为基站收发信台(base transceiver station，BTS)；宽带码分多址(wideband code division multiple access，WCDMA)中，网络设备11称为节点B(node B，NB)；长期演进(long term evolution，LTE)系统中，网络设备11称为演进型节点B(evolved node B，eNB)。网络设备11还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备11还可以是NR网络中的基站设备。网络设备11还可以是可穿戴设备或车载设备。网络设备11还可以是传输接收节点(transmission and reception point，TRP)。
终端设备12，用于获取第一信息，并向网络设备11发送第一信息。终端设备12，还用于接收来自网络设备11的配置信息和第一频段的指示信息，根据配置信息和指示信息确定第二频段的传输参数。
在一些实施例中，终端设备12可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，也可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与RAN交换语言和/或数据。例如，终端设备12可以为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control中的无线终端设备、无人驾驶(self driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等。图1中以终端设备12为手机为例示出。
上述网络设备11和终端设备12的基本硬件结构类似，都包括图2所示通信装置所包括的元件。下面以图2所示的通信装置为例，介绍网络设备11和终端设备12的硬件结构。
如图2所示，通信装置可以包括处理器21(或者，处理电路)和通信接口22(或者，接口电路)，通信接口22可用于与其他装置或设备进行通信。
可选的，通信装置还可以包括存储器23，用于存储计算机指令。处理器21和存储器23相互耦合，用于实现本申请下述实施例提供的传输参数确定方法。或者，通信装置也可以不包括存储器23，存储器23可以位于通信装置外部。
处理器21、存储器23和通信接口22相互耦合，用于实现本申请下述实施例提供的传输参数确定方法。例如，当处理器21执行存储器23存储的计算机指令时，使通信装置执行本申请下述实施例提供的传输参数确定方法。
例如，通信装置可以为通信设备(终端设备或网络设备)，或者为设置在通信设备中的芯片或其他部件。如果通信装置为通信设备，则通信接口22可以通过通信设备中的收发器(或者，发送器和接收器)实现，收发器可以通过通信设备中的天线、馈线和编解码器等实现。如果通信装置为设置在通信设备中的芯片，则通信接口22为芯片的输入/输出接口，例如输入/输出管脚等，该通信接口22与通信设备中的射频收发组件连接，以通过射频收发组件实现信息的收发。
处理器21是通信装置的控制中心，可以是一个处理器，也可以是多个处理元件的统称。例如，处理器21可以是一个通用中央处理单元(central processing unit，CPU)，也可以是其他通用处理器等。其中，通用处理器可以是微处理器或者是任何常规的处理器等，例如，通用处理器可以是图形处理器(graphics processing unit，GPU)、数字信号处理器(digital signal processing，DSP)等。
存储器23可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。
在本申请实施例中，对于网络设备11和终端设备12而言，存储器22中存储的软件程序不同，所以网络设备11和终端设备12实现的功能不同。关于各设备所执行的功能将结合下面的流程图进行描述。
通信接口22，用于通信装置与其他设备通过通信网络连接，通信网络可以是以太网，RAN，无线局域网(wireless local area networks，WLAN)等。通信接口22可以包括用于接收数据的接收单元，以及用于发送数据的发送单元。
图2中示出的结构并不构成对该通信装置的限定，除图2所示部件之外，该通信装置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。
需要说明的是，本申请实施例中，终端设备支持多个频段通信的能力是通过终端设备中设置的多个天线面板来实现的，通常一个频段对应一个或多个天线面板。
示例性的，图2a为终端设备中的四个天线面板的布局示意图。如图2a所示，用不同填充物的矩形来表示不同频段对应的天线面板，用不同填充物的水滴形表示不同频段的波束。假设终端设备支持第一频段和第二频段通信的能力，第一频段对应天线面板1和2，第二频段对应天线面板3和4。
由图2a可知，对于天线面板1和天线面板4，第一频段和第二频段使用不同的天线面板，所以相应的两个波束没有空间的相关性。对于天线面板2和天线面板3，第一频段和第二频段使用的是集成在一起的天线面板，所以相应的两个波束具有空间的相关性。
再例如，图2b为网络设备中的第一频段的天线面板和第二频段的天线面板的布 局示意图。如果第一频段的天线面板和第二频段的天线面板具有一定的一致性假设，那么如图2b所示，第一频段的天线面板和第二频段的天线面板可以共面，也可以上下拼接。
基于上述通信系统和通信装置的硬件结构的介绍，本申请实施例提供一种传输参数确定方法，下面结合附图对本申请实施例提供的传输参数确定方法进行描述。
如图3所示，传输参数确定方法可以包括以下步骤301-步骤302。
301、终端设备获取配置信息和第一频段的指示信息。
指示信息用于指示第一频段的传输参数，配置信息用于指示第一频段的传输参数用于第一频段和第二频段。第一频段对应的第一天线面板和第二频段对应的第二天线面板具有相关关系，该相关关系用于表征第一天线面板和第二天线面板满足预设条件。具体的，相关关系用于表征第一天线面板的位置和第二天线面板的位置满足预设条件。例如，预设条件可以为：多个频段的天线面板集成在一起，或者多个频段的天线面板之间的距离小于预设值，或者多个频段的天线面板封装在一个芯片中，或者多个频段的天线面板位于终端的同一侧/面，或者多个频段的天线面板紧密拼接等等。
在具体实现中，配置信息用于指示第一频段的传输参数用于包括第一频段在内的多个频段，多个频段中的每个频段对应一个天线面板，多个频段对应的多个天线面板之间具有相关关系，本申请实施例是以第一频段和第二频段为例进行说明的。
在一些实施例中，指示信息可以为TCI指示信息，或者为空域关系(spatial relation)指示信息。
可选的，在本申请实施例中，第一频段的传输参数包括以下至少一种：第一频段的接收波束参数、第一频段的发送波束参数、偏移关系和第一频段的上行发送功率。其中，偏移关系用于表征第二频段的上行发送功率和第一频段的上行发送功率之间的关系。
在一些实施例中，第一频段的接收波束参数包括以下至少一种：接收波束、接收空域滤波器参数、接收信号的QCL关系、接收信号的时偏补偿、接收信号的时域扩展、接收信号的频偏补偿、接收信号的多普勒偏移。
在一些实施例中，第一频段的发送波束参数包括以下至少一种：发送波束、发送空域滤波器参数、发送信号的空间关系、发送信号的功率控制参数、发送信号的定时、发送信号的路径损耗参考信号。
可选的，在本申请实施例中，配置信息是网络设备发送给终端设备的，配置信息指示的第一频段的传输参数是网络设备通过在第一频段上与终端设备建立连接来获得的。示例性的，假设第一频段的传输参数为第一频段的接收波束参数和发送波束参数，那么第一频段的接收波束参数和发送波束参数可以通过在第一频段上进行波束扫描来得到。例如，波束扫描的过程可以为：网络设备向终端设备发送下行参考信号(如SSB、CSI-RS)，终端设备上报下行参考信号的测量结果，如最优波束的参考信号接收功率(reference signal received power，RSRP)。网络设备基于终端设备上报的测量结果，确定通信的波束。对于波束扫描，还可以采用其他的方法进行，本申请实施例在此对波束扫描的具体实现过程不做限定。
可选的，本申请实施例中，上述指示信息具体用于指示第一天线面板的传输参数， 配置信息具体用于指示第一天线面板的传输参数用于第一天线面板和第二天线面板。
302、终端设备根据配置信息和指示信息，确定第二频段的传输参数。
终端设备在获取到配置信息和第一频段的指示信息之后，可以根据配置信息得到第一频段的传输参数，并根据指示信息获知第一频段的传输参数能够用于第一频段和第二频段，从而便可以根据第一频段的传输参数确定第二频段的传输参数。
可选的，在本申请实施例中，第一频段的传输参数包括第一频段的接收波束参数的情况下，终端设备根据配置信息和指示信息，确定第二频段的传输参数具体可以为：终端设备确定第二频段的接收波束参数包括第一频段的接收波束参数。
示例性的，如图4所示，假设指示信息用于指示第一频段的接收波束参数，第一频段的接收波束参数包括：接收波束2，配置信息用于指示接收波束2用于第一频段和第二频段，那么终端设备可以确定第二频段的接收波束为接收波束2，即终端设备将使用接收波束2接收网络设备在第二频段上发送的信号。
第一频段的传输参数包括第一频段的发送波束参数的情况下，终端设备根据配置信息和指示信息，确定第二频段的传输参数具体可以为：终端设备确定第二频段的发送波束参数包括第一频段的发送波束参数。
可选的，在本申请实施例中，第一频段的传输参数包括偏移关系和第一频段的上行发送功率的情况下，终端设备根据配置信息和指示信息，确定第二频段的传输参数具体可以为：终端设备根据偏移关系和第一频段的上行发送功率，确定第二频段的上行发送功率。这样，由于上行发送功率是由信令控制的，本申请实施例中第一频段和第二频段的上行发送功率能够由同一套信令控制，与现有技术中的每个频段的上行发送功率由一套信令控制相比，本申请实施例能够减少信令开销，从而提高通信效率。
需要说明的是，本申请实施例是以第一频段的传输参数包括偏移关系和第一频段的上行发送功率为例说明的。可以理解，该情况下，偏移关系携带在配置信息中，由网络设备发送给终端设备，偏移关系是预先配置在网络设备中的。当然，第一频段的传输参数也可以仅包括偏移关系。该情况下，偏移关系是预先配置在网络设备中的，终端设备可以自己获取第一频段的上行发送功率。或者，第一频段的传输参数也可以仅包括第一频段的上行发送功率。该情况下，偏移关系可以是协议预先规定的，或者是预先配置在终端设备中的。本申请实施例在此对偏移关系的来源不做限定。
可选的，在本申请实施例中，在上述步骤301中指示信息具体用于指示第一天线面板的传输参数，配置信息具体用于指示第一天线面板的传输参数用于第一天线面板和第二天线面板的情况下，终端设备根据配置信息和指示信息，确定第二频段的传输参数具体可以为：终端设备根据配置信息和指示信息，确定第二天线面板的传输参数。
本申请实施例提供的传输参数确定方法，终端设备获取用于指示第一频段的传输参数的配置信息，以及用于指示第一频段的传输参数用于第一频段和第二频段的指示信息，并根据配置信息和指示信息确定第二频段的传输参数，即根据第一频段的传输参数确定第二频段的传输参数。这样，在第一频段对应的第一天线面板和第二频段对应的第二天线面板具有相关关系时，终端设备能够直接根据第一频段的传输参数确定出第二频段的传输参数，无需在第二频段上进行扫描来获得第二频段的传输参数，降低了通信开销，提高了通信效率。
可选的，本申请实施例中，基于图3，如图5所示，上述步骤301具体可以包括以下步骤301A-301F。
301A、终端设备获取第一信息。
其中，第一信息用于表征终端设备中存在具有相关关系的第一天线面板和第二天线面板。在具体实现中，第一信息可以用于表征终端设备中存在具有相关关系、且频段不同的多个天线面板，本申请实施例中以具有相关关系、频段不同的两个天线面板为例进行说明。
在一些实施例中，第一信息可以是预先存储在终端设备中的，也可以是终端设备通过分析该终端设备中的天线面板的布局情况得到的。本申请实施例在此对第一信息的获取方式不做限定。
在一些实施例中，第一信息可以有以下多种实现方式。本申请实施例在此对第一信息的具体实现方式不做限定，能够用于表征终端设备中存在具有相关关系的第一天线面板和第二天线面板即可。
1、第一种实现中，第一信息可以包括第一天线面板的位置信息和第二天线面板的位置信息。通过分析第一天线面板的位置信息和第二天线面板的位置信息，能够获知第一天线面板和第二天线面板具有相关关系。
2、第二种实现中，第一信息可以包括第一天线面板的标识和第二天线面板的标识，以及相关关系信息。
在一些实施例中，天线面板(panel)的标识的表示方式可以为：天线面板对应的频段信息+天线面板编号。其中，频段信息可以为频段编号或者频段所属的频段范围。天线面板编号可以表示该天线面板在该天线面板对应的频段对应的所有天线面板中的编号，也可以表示该天线面板在终端设备的所有天线面板中的编号。本申请实施例在此对天线面板的标识的表示方式不做限定。
示例性的，假设频段范围包括FR1和FR2。如表1所示，为FR1中的频段。如表2所示，为FR2中的频段。
表1
Figure PCTCN2021072557-appb-000001
表2
Figure PCTCN2021072557-appb-000002
由表1和表2可知，天线面板的标识可以为：n78panel#1，n78表示频段编号，panel#1表示n78频段对应的所有天线面板中的1号天线面板。
天线面板的标识可以为：FR1panel#1，FR1表示频段范围，panel#1表示终端设备包括的所有天线面板中的1号天线面板。
在一些实施例中，相关关系信息用于表征第一天线面板和第二天线面板的相关程度。相关程度可以包括高相关(high correlation)、低相关(low correlation)等。在具体实现中，如果两个天线面板集成在一起，则这两个天线面板具有高相关关系。如果两个天线面板的位置相邻，则这两个天线面板具有低相关关系。如果两个天线面板的距离较远，则这两个天线面板不相关。
示例性的，如图6所示，终端设备中，假设第一频段n78对应天线面板1、3、6，第二频段n257对应天线面板2、4、5。且假设天线面板1的标识为n78panel#1，天线面板3的标识为n78panel#3，天线面板6的标识为n78panel#6。天线面板2的标识为n257panel#2，天线面板4的标识为n257panel#4，天线面板5的标识为n257panel#5。假设天线面板1和天线面板2的相关关系信息用于表征天线面板1和天线面板2的相关程度为高相关，天线面板3和天线面板4的相关关系信息用于表征天线面板3和天线面板4的相关程度为低相关。那么第一信息可以包括：high correlation：{n78panel#1，n257panel#2}；low correlation：{n78panel#3，n257panel#4}。
可选的，在本申请实施例中，在第一信息中包括相关关系信息，且相关关系信息用于表征的相关程度包括高相关、低相关的场景下，上述步骤302中的终端设备确定第二频段的接收波束参数包括第一频段的接收波束参数具体可以包括：若相关程度为高相关，则终端设备可以确定第一频段的所有接收波束参数能够用于第二频段。若相关程度为低相关，则终端设备可以确定第一频段的部分接收波束参数能够用于第二频段。例如，该部分参数可以包括：接收波束。同理，上述步骤302中的终端设备确定第二频段的发送波束参数包括第一频段的发送波束参数具体可以包括：若相关程度为高相关，则终端设备可以确定第一频段的所有发送波束参数能够用于第二频段。若相关程度为低相关，则终端设备可以确定第一频段的部分发送波束参数能够用于第二频段。例如，该部分参数可以包括：发送波束。
3、第三种实现中，第一信息可以包括第一天线面板的标识和第二天线面板的标识，第一天线面板的标识和第二天线面板的标识属于一个天线面板集合。属于同一个天线面板集合的多个天线面板具有相关关系。
示例性的，结合上述第二种实现中的例子，第一信息可以包括：{n78 panel#1，n257 panel#2}、{n78 panel#3，n257 panel#4}。
需要说明的是，在本申请实施例中，在终端设备中存在与其他天线面板都不具有相关关系的天线面板的情况下，第一信息还可以用于表征终端设备中存在与其他天线面板均不具有相关关系的天线面板，如第四天线面板。具体的实现中，第一信息还可以包括：第四天线面板的位置信息。或者，第一信息还可以包括第四天线面板的标识和不相关信息，该不相关信息用于指示第四天线面板与其他天线面板均不相关。或者，第一信息还可以包括：第四天线面板的标识，该第四天线面板的标识属于一个天线面板集合，该集合中仅有一个标识。当然，第一信息也可以不用于表征与其他天线面板 不相关的天线面板。
301B、终端设备向网络设备发送第一信息。
301C、网络设备接收来自终端设备的第一信息。
301D、网络设备基于第一信息得到配置信息和第一频段的指示信息。
网络设备在接收到来自终端设备的第一信息之后，可以基于该第一信息获得终端设备中的具有相关关系的第一天线面板和第二天线面板，为终端设备配置资源，从而得到用于指示第一频段的传输参数的配置信息，以及用于指示第一频段的传输参数用于第一频段和第二频段的第一频段的指示信息。
在一些实施例中，配置信息具体可以包括参考信号资源。参考信号资源可以包括：SRS、CSI-RS、SSB等。参考信号资源的类型不同，确定出的第一频段的传输参数可能不同，也就是说，配置信息用于指示的第一频段的传输参数可能不同。例如，SRS用于终端设备确定至少一种参数：发送空域滤波器参数、发送信号的功率控制参数。CSI-RS用于终端设备确定至少一种参数：接收波束、接收空域滤波器参数、接收信号的QCL关系、接收信号的时偏补偿、接收信号的时域扩展、接收信号的频偏补偿、接收信号的多普勒偏移。SSB用于终端设备确定至少一种参数：发送波束、发送空域滤波器参数、发送信号的空间关系、发送信号的功率控制参数、发送信号的定时、发送信号的路径损耗参考信号、接收波束、接收空域滤波器参数、接收信号的QCL关系、接收信号的时偏补偿、接收信号的时域扩展、接收信号的频偏补偿、接收信号的多普勒偏移。
在一些实施例中，网络设备在确定第一频段的指示信息时有多种实现。一种实现中，可以同时给具有相关关系的多个天线面板对应的多个频段确定统一的指示信息。另一种实现中，可以分别给具有相关关系的多个天线面板对应的多个频段中的每个频段确定指示信息。
301E、网络设备向终端设备发送配置信息和指示信息。
301F、终端设备接收来自网络设备的配置信息和指示信息。
这样，通过终端设备向网络设备上报第一信息，使得网络设备实现了跨载波波束管理，从而使得不同频段之间的传输参数能够耦合和互用，大大降低了通信开销。
可选的，本申请实施例提供的传输参数确定方法还可以应用于天线面板切换场景。具体的，传输参数确定方法还可以包括：终端设备在确定第二频段对应的第三天线面板与网络设备的连接断开的情况下，从第三天线面板切换到第二天线面板，根据配置信息和指示信息，确定第二天线面板的传输参数。且，终端设备可以向网络设备发送切换指示信息，该切换指示信息用于指示终端设备从第三天线面板切换到第二天线面板。在具体的实现中，切换指示信息可以包括待切换的第三天线面板的标识，以及切换后的第二天线面板的标识。网络设备在接收到来自终端设备的切换指示信息之后，可以获知终端设备的天线面板的切换情况，并根据切换情况，进行资源的重配置。
在一些实施例中，终端设备可以在确定第三天线面板被遮挡、第三天线面板被损坏等的情况下，确定第三天线面板与网络设备的连接断开。
这样，由于第二天线面板与第一天线面板具有相关关系，因此可以直接从第三天线面板切换到第二天线面板。通过终端设备主动触发天线面板的切换，无需重新进行 扫描，能够降低通信开销，提高通信效率。
示例性的，结合图6，如图7所示，假设天线面板1为第三天线面板，天线面板3为第二天线面板，天线面板1和天线面板3对应第一频段。终端设备确定天线面板1与网络设备的连接断开时，可以在确定天线面板3与天线面板1对应同一个频段，且天面面板3与天线面板4具有相关关系的情况下，从天线面板1切换到天线面板3。
本申请实施例提供的传输参数确定方法还可以包括：终端设备获取第一频段的指示信息，该指示信息用于指示第一频段的传输参数；确定第一频段对应的第一天线面板和第二频段对应的第二天线面板具有相关关系；根据指示信息和相关关系，确定第二频段的传输参数。
这样，终端设备在获取到第一频段的指示信息后，可以获知第一频段的传输参数，且终端设备可以确定其包括的第一频段对应的第一天线面板和第二频段对应的第二天线面板具有相关关系，从而终端设备可以确定第一频段的传输参数能够用于第二频段。之后，终端设备便可以根据第一频段的传输参数确定出第二频段的传输参数。
可选的，在本申请实施例中，指示信息具体用于指示第一天线面板的传输参数。该情况下，终端设备根据指示信息和相关关系，确定第二频段的传输参数，具体可以包括：终端设备根据指示信息和相关关系，确定第二天线面板的传输参数。
可选的，在本申请实施例中，上述终端设备获取第一频段的指示信息，具体可以包括：终端设备获取第一信息，向网络设备发送第一信息，接收来自网络设备的指示信息。
