Description

传输信息的方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及通信领域中传输信息的方法和装置。
背景技术
在高速数据传输的情况下，终端设备由于配置了高的多输入多输出的无线天线层数(multiple-input multiple-output layer，MIMO layer)、大带宽和多载波，会导致终端设备出现过热问题。此外，高MIMO，大带宽和多载波配置也会导致终端设备的功率消耗过高的问题。
为了解决终端设备的过热问题，或者优化终端设备的功耗，需要在终端设备和网络设备之间进行不同的信息交互。当终端设备在出现过热问题或者过热问缓解后，可以向基站发送带有过热指示信息的辅助信息(UE assistance information)，以便基站可以调整为终端设备配置的通信参数，例如辅小区数、天线层数MIMO layer，天线端口数和最大聚合带宽等，以解决当前终端设备的过热问题。当终端设备期望降低通信配置以便降低功耗时，终端设备也可以向基站发送辅助信息，以便基站可以调整为终端设备配置的通信参数，例如辅小区数、天线层数MIMO layer，天线端口数和最大聚合带宽等。
但是，对于多空口双连接(multi-radio dual connectivity，MR-DC)的网络架构，通过两个接入网设备(主基站和辅基站)同时为终端设备提供业务传输。当终端设备出现过热问题，或者终端设备期望降低功耗时，除了主基站需要调整为终端设备配置的通信参数，辅基站也需要调整为终端设备配置的通信参数，以解决终端设备的过热问题或者降低终端设备的功耗。另外，对于基于CU-DU的接入网架构，当终端设备出现过热问题或者期望降低功耗时，除了CU需要调整为终端设备配置的通信参数外，DU也需要调整为终端设备配置的通信参数，以解决终端设备的过热问题或者降低终端设备的功耗。
发明内容
本申请提供了一种传输信息的方法和装置，该方法能够为终端设备配置合适最大MIMO layer数、最大SCell数目或者最大聚合带宽，以解决终端设备过热问题。
第一方面，提供了一种传输信息的方法，包括：第一网络设备接收终端设备发送的第一消息，该第一消息包括第一过热辅助信息，该第一过热辅助信息用于指示该终端设备是否过热；该第一网络设备根据该第一过热辅助信息，确定第二消息，该第二消息用于指示第二网络设备调整为该终端设备配置的通信参数，该通信参数包括以下至少一种参数：上行辅小区数、下行辅小区数、上行多输入多输出的无线天线层MIMO layer数、下行MIMO layer数、上行聚合带宽、下行聚合带宽；第一网络设备向该第二网络设备发送该第二消息。
结合第一方面，在一些可能的实现方式中，该通信参数可以包括终端设备期望临时配置的最大上行辅小区(Scell)数、最大下行辅小区(Scell)数、FR1频段范围(<6GHz的频段)的服务小区上的最大上行MIMO layer数、FR1的服务小区上的最大下行MIMO layer数、FR2频段范围(>6GHz的频段)的服务小区上的最大上行MIMO layer数、FR2的服务小区上的最大下行MIMO layer数，FR1上的上行载波的最大上行聚合带宽，FR1上的下行载波的最大下行聚合带宽，FR2上的上行载波的最大上行聚合带宽和FR2上的下行载波的最大下行聚合带宽中的至少一种。
结合第一方面，在一些可能的实现方式中，所述辅助信息中的最大MIMO layer数(包括FR1上的服 务小区的最大上行MIMO layer数、FR1上的服务小区的最大下行MIMO layer数、FR2上的服务小区的最大上行MIMO layer数和FR2上的服务小区的最大下行MIMO layer数中的至少一个)可以是终端设备期望SN配置的SCG的服务小区上的最大MIMO layer数；或者也可以是终端设备期望MN配置的MCG的服务小区上的最大MIMO layer数；或者也可以是终端设备期望MN配置的MCG的服务小区以及SN配置SCG的服务小区上的最大MIMO layer数；或者也可以分别包含终端设备期望MN配置的MCG的服务小区上的最大MIMO layer数以及SN配置SCG的服务小区上的最大MIMO layer数。
结合第一方面，在一些可能的实现方式中，所述辅助信息中的最大聚合带宽(包括FR1上的上行载波的最大上行聚合带宽，FR1上的下行载波的最大下行聚合带宽，FR2上的上行载波的最大上行聚合带宽和FR2上的下行载波的最大下行聚合带宽中的至少一个)可以是终端设备期望SN配置的载波的最大聚合带宽值；或者也可以是终端设备期望MN配置的载波和SN配置的载波的聚合带宽的和的最大值。
应理解，该第二消息还可以用于请求第二网络设备为终端设备配置通信参数。
还应理解，上述第二消息还可以不包括任何通信参数。当终端设备过热问题解决之后，该第二消息不包括任何与通信参数有关的信息，本申请对此不作限定。
可选地，该第一消息是终端设备向MN发送的带有过热辅助信息的消息。当终端设备出现过热时，会向MN发送过热消息，该过热消息中包括过热辅助信息，过热辅助信息可以包括该终端设备当前支持的通信参数，该通信参数是可以解决终端设备过热问题的参数配置。
应理解，终端设备在和该MN和SN建立连接时，MN和SN可以获取到终端设备的无线通信能力(radio capability)，终端设备在过热情况下上报的通信参数小于该无线通信能力对应的通信参数。
例如，根据终端设备的无线通信能力，终端设备在非过热情况下，可以支持31个SCell当终端设备出现过热时，终端设备向MN发送的过热辅助信息中指示当前终端设备期望的临时配置最大的Scell数的为6个，换言之，只有MN和SN分别为终端设备配置的Scell数的总和小于或等于6个时，才可以解决终端设备的过热问题。
还应理解，当终端设备出现过热，在MR-DC场景中，终端设备向MN上报的过热辅助信息中都可以包括最大Scell数。此外，对于NE-DC和NR-DC场景中，终端设备向MN上报的过热辅助信息中可以包括最大Scell数、最大MIMO layer数和最大聚合带宽中的至少一种。
结合第一方面，在某些可能的实现方式中，该方法还包括：该第一网络设备接收该第二网络设备发送的第三消息，该第三消息为该第二消息的响应消息，且该第三消息用于指示该第二网络设备为该终端设备配置的通信参数。
当终端设备出现过热时，会在过热辅助信息中携带当前支持的通信参数。当终端设备过热问题解决时，该过热辅助信息中不包括任何信息。因此，MN可以根据过热辅助信息中是否携带信息来判断终端设备当前是否过热。
MN接收终端设备发送的过热消息，根据过热消息中过热辅助信息确定终端设备发生了过热问题。当MN确定终端设备发生过热问题之后，MN和SN需要按照终端设备期望的通信参数，为终端设备配置通信参数，从而解决终端设备的过热问题。MN可以通过第二消息指示SN需要调整为该终端设备配置的通信参数，针对通信参数包括的不同类型，该第二消息可以对应包括不同的信息。此外，SN会将为终端设备配置的通信参数通过第三消息告诉MN，该第三消息可以理解为第二消息的响应消息。针对第二消息包括不同的信息种类，该第三消息对应包括不同的信息种类，具体请参见实施例部分相关描述。
通过上述技术方案，在双连接的网络架构中，对于主节点设备(MN)和辅节点设备(SN)，当终端 设备发生过热问题时，MN可以向SN通知终端设备发生过热问题，或者向SN提供MN确定的用于解决终端设备过热问题的辅助信息。该辅助信息可以包括MN指示SN可以或者被允许为终端设备配置的通信参数，或者该辅助信息可以包括终端设备上报的用于解决过热问题的通信参数。使得SN可以从MN提供的辅助信息中，选择用于解决终端设备过热问题的通信参数，从而为终端设备配置通信参数。当终端设备工作于MR-DC场景下发生过热问题后，能够让SN为终端设备配置合适最大MIMO layer数、最大SCell数目或者最大聚合带宽以帮助终端设备缓解过热问题。当终端设备过热问题解决时，MN还可以向SN通知终端设备过热问题已经解决，并可以恢复终端设备所支持的最大能力的配置或者终端设备原来和MN、SN连接时的配置。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、第五代(5th generation，5G)移动通信系统或新无线(new radio，NR)通信系统以及未来的移动通信系统等。
图1是适用于本申请实施例的移动通信系统的架构示意图。如图1所示，该移动通信系统100可以包括核心网设备110、无线接入网设备120和至少一个终端设备(如图1中的终端设备130和终端设备140)。终端设备通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网设备连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端设备可以是固定位置的，也可以是可移动的。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图1中未画出。本申请的实施例对该移动通信系统中包括的核心网设备、无线接入网设备和终端设备的数量不做限定。
在移动通信系统100中，无线接入网设备120是终端设备通过无线方式接入到该移动通信系统中的接入设备。该无线接入网设备120可以是：基站、演进型基站(evolved node B，eNB)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的基站(gNode B，gNB)，或者，还可以是构成基站的组件或一部分设备，如汇聚单元(central unit，CU)、分布式单元(distributed unit，DU)或基带单元(baseband unit，BBU)等。应理解，本申请的实施例中，对无线接入网设备所采用的具体技术和具体设备形态不做限定。在本申请中，无线接入网设备简称网络设备，如果无特殊说明，在本申请中，网络设备均指无线接入网设备。在本申请中，网络设备可以是指网络设备本身，也可以是应用于网络设备中完成无线通信处理功能的芯片。

在第五代(the fifth generation，5G)移动通信系统的初始阶段，由于第四代(the forth generation，4G)移动通信系统网络和5G新无线(new radio，NR)通信系统网络会共存，为了充分利用现有的4G网络，运营商会部署通过4G接入网，即演进的UMTS陆地无线接入网(evolved UMTS terrestrial radio access network，E-UTRAN)和5G接入网(NR)同时为终端设备提供业务传输的网络。另外也可以部署通过两个5G NR接入网同时为终端设备提供业务传输的网络。这种通过两个接入网设备同时为终端设备提供业务传输的网络架构称为多空口双连接(multi-radio dual connectivity，MR-DC)。
具体地，如图2中的(a)图所示的网络架构，以LTE基站(eNB)为主基站(master node)，NR基站(gNB)为辅基站(secondary node)，并且主基站连接到4G核心网(evolved packet core，EPC)的双连接方式(E-UTRAN-NR dual connectivity，EN-DC)。
如图2中的(b)图所示的网络架构，是以演进的LTE基站(next generation evolved node B，Ng-eNB)为主节点，NR基站(gNB)为辅基站，并且主基站连接到5G核心网(5G core，5GC)的双连接方式(NG-RAN E-UTRA-NR dual connectivity，NGEN-DC)。
如图2中的(c)图所示的网络架构，是以NR基站为主基站，LTE基站为辅基站，并且主基站连接到5G核心网的双连接方式(NR-E-UTRA dual connectivity，NE-DC)。
如图2中的(d)图所示的网络架构，是以一个NR基站为主基站，另外一个NR基站为辅基站，并且主基站连接到5G核心网的双连接方式(NR-NR dual connectivity，NR-DC)。
如背景技术所介绍，终端设备在高速数据传输的情况下，会出现过热问题。为了解决终端设备的过热问题，目前标准中规定了终端设备在出现过热问题或者过热问缓解后，终端设备可以向基站发送带有过热辅助(overheating asssistance)信元的过热消息(UE assistance information)。在终端设备发生过热问题时，过热辅助信元中会包含终端设备提供的过热辅助消息；在终端设备过热问题缓解后，过热辅助信元不包含任何的过热辅助消息。此外，当终端设备期望降低功耗时，终端设备也可以发送辅助信息，向基站上报自己期望的配置。
针对上述图2中介绍的四种不同的MR-DC网络架构的场景，终端设备上报的过热辅助信息不同。具体地，当终端设备工作于4G独立组网(long term evolution standard alone，LTE SA)场景下时，过热辅助信息可以包括：终端设备支持的上行链路(uplink，UL)或者下行链路(downlink，DL)的分类；终端设备支持的UL/DL上临时配置的辅小区(secondary cell，Scell)的最大数目。当终端设备工作于EN-DC场景下时，辅助信息可以包括：终端设备支持的UL/DL临时配置的Scell的最大数目，并 且该Scell的数目是指LTE下的Scell和NR下的PScell/Scell的总和，其中PScell为主基站为终端设备配置的辅小区。当终端设备工作在5G独立组网(new radio standard alone，NR SA)场景下时，NR基站独立工作，并且NR基站连接到5G核心网。辅助信息可以包括：终端设备支持的UL/DL上临时配置的Scell的最大数目；终端设备支持的UL/DL上临时配置的每个频率范围(Frequency Range)的最大MIMO layer数；终端设备支持的UL/DL上临时配置的每个频率范围FR的最大聚合带宽。
由此可知，当终端设备工作于图2中任一种MR-DC场景下，终端设备发生过热问题时或者需要降低功耗时，终端设备会向主基站MN上报带有用于解决过热问题或者用于降低功耗的辅助信息的消息。以终端设备发生过热问题为例，图3是本申请实施例提供的一例终端设备过热时和基站之间的交互示意图。如图3所示，该过程包括：
1.终端设备确定出现过热；
2.终端设备向MN上报带有过热辅助信元的过热消息，该过热消息用于指示终端设备期望临时配置的Scell的最大数目；
3.MN收到终端设备上报的过热消息后，获取过热辅助信元中的Scell的最大数目。MN决定MN和SN各自给终端设备配置的Scell的最大数目，MN根据终端设备的能力确定为终端设备配置的频段组合列表(band combination list，BC-list)；
4.MN向SN发送修改请求(SN modification request)，该修改请求包括MN确定过的BC-list通知给SN。
通过上述过程可知，当MN确定SN可以为终端设备配置的Scell的最大数目后，可以通过设置合适的allowed BC-list MR-DC来限制SN给终端设备配置的最大的Scell的数目，并发起SN修改过程，在SN修改请求消息中携带更新后的allowed BC-List MR-DC，并发给SN。在该过程中，当MN为了通过降低载波数来解决终端设备过热问题而更新allowed BC-list MR-DC后，SN无法获知MN更新的原因，在SN为终端设备配置Scell的过程中，可能会请求其它的不能解决终端设备过热问题的Scell数，SN将重新请求的Scell数再告诉MN，造成MN和SN之间的不必要的信令交互。此外，通过allowed BC-list MR-DC无法分别限制SN能够给终端设备配置的上行载波数和下行载波数。因此，通过现有协议中的修改请求向SN通知可以为终端设备配置的Scell数，并不能解决终端设备过热问题。
在另外一种可能的情况中，当终端设备发生过热问题后，或者期望降低功耗时，终端设备向MN上报带有辅助信息的消息。此时，终端设备向MN上报的消息中，除了前述终端设备支持临时配置的Scell的最大数目之外，还可以包括终端设备支持的临时配置的最大MIMO layer数和/或支持的临时配置的最大聚合带宽。当MN收到终端设备上报的终端设备支持的临时配置的最大MIMO layer数和/或支持的临时配置的最大聚合带宽后，目前MN并不能将终端设备支持的临时配置的最大MIMO layer数和/或支持的临时配置的最大聚合带宽通知到SN，即无法让SN知道可以为终端设备临时配置的最大MIMO layer数和可以为终端设备临时配置的最大聚合带宽，从而不能解决终端设备的过热问题，或者无法修改配置来为终端设备降低功耗。
为了解决终端设备的过热问题或者为终端设备降低功耗，本申请提出一种传输信息的方法，通过在网络设备间的信息交互，使得辅基站能够知道终端设备发生过热问题或者终端设备期望降低功耗，进而为终端设备配置合适的辅小区数、最大MIMO layer数和最大聚合带宽，或者能够按照终端设备支持的最大MIMO layer数来为终端设备调度上行和/或下行的数据传输。
如下实施例以终端发生过热问题为例来说明本申请的方法。应理解，当终端期望降低功耗时，终端设备也可以向网络设备发送辅助信息，辅助信息中例如可以包括终端设备期望MIMO layer数，聚合带 宽，辅小区数。因此，如下实施例中的方法也适用于解决终端设备的功耗问题。
图4是本申请实施例提供的一例传输信息的方法400的示意性交互图。下面，对方法400的每个步骤进行详细说明。
应理解，在本申请实施例中，以终端设备和基站(主基站MN和辅基站SN)作为执行方法400的执行主体为例，对方法400进行说明。作为示例而非限定，执行方法400的执行主体也可以是应用于终端设备的芯片和应用于基站的芯片。
S401，终端设备确定出现过热；或者终端设备期望降低功耗。

例如，根据终端设备的无线通信能力，终端设备在非过热情况下，可以支持31个SCell当终端设备出现过热时，终端设备向MN发送的过热辅助信息中指示当前终端设备期望的临时配置最大的Scell数的为6个，换言之，只有MN和SN为终端设备配置的Scell数的总和小于或等于6个时，才可以解决终端设备的过热问题。
又例如，根据终端设备的无线通信能力，终端设备在非过热情况下，可以支持的FR1频段范围(<6GHz的频段)上的上行载波的最大聚合带宽为100M，即MN和SN为终端设备配置的FR1频段范围上的上行载波的最大聚合带宽的总和为100M。当终端设备出现过热时，终端设备向MN发送的过热辅助信息中指示当前终端设备期望的临时配置最大聚合带宽的为20M，换言之，只有MN和SN为终端设备配置的最大聚合带宽的总和小于或等于20M时，才可以解决终端设备的过热问题。

应理解，在S402中，介绍了当终端设备出现过热时，会在过热辅助信息中携带当前支持的通信参数。当终端设备过热问题解决时，该过热辅助信息中不包括任何信息。因此，MN可以根据过热辅助信息中是否携带信息来判断终端设备当前是否过热。
此外，应理解，当终端设备期望降低功耗时，会在用于降低功耗的辅助信息中携带当前支持的通信参数。当终端设备不期望降低功耗时，该辅助信息中不包括任何信息。因此，MN可以根据用于降低功耗的辅助信息中是否携带信息来判断终端设备当前是否期望降低功耗。

可选地，MN确定终端设备的过热问题已经解决时，可以在该第二消息中还包括第七信息，该第七信息用于指示该终端设备过热问题解决。

应理解，在这种情况下，MN发送给SN的最大MIMO layer数就为终端设备上报的最大MIMO layer数。因此，该第二消息就可以包含终端设备上报的所期望配置的MIMO layer数。可选的，MN和SN为终端设备配置的最大MIMO layer相等，或者第二消息中包含的终端设备上报的所期望配置的MIMO layer数为终端设备期望SN配置的SCG的服务小区上的最大MIMO layer数。此时，第三消息可以包括该最大MIMO layer数，也可以不包括该最大MIMO layer数，本申请对此不做限定。

应理解，针对图2列举的多种MR-DC场景中，终端设备向MN上报的过热辅助信息中都可以包括最大Scell数、最大MIMO layer数和最大聚合带宽中的至少一种。因此，对于MR-DC场景，MN向SN发送的第二消息(辅节点修改请求消息)中可以包括最大上行辅小区数、最大下行辅小区数、最大上行MIMO layer数、最大下行MIMO layer数、最大上行聚合带宽、最大下行聚合带宽中的至少一种。
在另一种可能的实现方式中，当该终端设备发生过热问题或者终端设备期望降低功耗时，该第二消息还包括第二过热辅助信息或者用于降低功耗的辅助信息，该第二过热辅助信息中或者用于降低功耗的辅助信息中包括该第一信息，第二信息，第三信息，第四信息和第五信息中的至少一项，当该终端设备过热问题解决或者终端设备不再期望降低功耗时，该第二过热辅助信息中或者用于降低功耗的辅助信息中不包含任何信息。
应理解，这里的第二过热辅助信息不同于前述的第一辅助信息。
此外，当终端设备过热问题解决或者终端设备不再期望降低功耗时，该第二过热辅助信息中或者用于降低功耗的辅助信息中可以不包括任何信息内容，也可以仅包括第七信息，即用于通知SN，终端设备的过热问题已经解决或者该终端设备不再期望降低功耗。
下面对于上述列举的各种信息，可以承载在第二消息(辅节点修改请求消息)中不同的信元中。
在一种可能的实现方式中，上述介绍的第一信息，第二信息，第三信息、第四信息、第五信息、第二过热辅助信息，用于降低功耗的辅助信息可以包含在信元ConfigRestrctInfoSCG中。
在另外一种可能的实现方式中，上述介绍的第一信息，第二信息，第三信息、第四信息、第五信息、第二过热辅助信息，用于降低功耗的辅助信息可以包含在信元MRDC-assistanceInfo中。在一种可能的实现方式中，上述的第六信息和第七信息可以通过以下几种方式包含在以下任意一种信元中：
1、包含在ConfigRestrctInfoSCG或者MRDC-assistanceInfo中
可选地，当第二消息包括频段组合列表时，第六信息是MN通知SN发送频段组合列表的原因是由于终端设备发生过热问题，或者是由于终端设备期望降低功耗；或者，第六信息是MN通知SN发送ConfigRestrictInfoSCG的原因是由于终端设备发生过热问题，后者是由于终端设备期望降低功耗。
2、包含在CG-ConfigInfo中
3、直接包含在S-Node modification request消息中
具体地，在现有的S-Node modification request消息中包含的cause中增加两个值来分别指示MN发送S-Node modification request消息或者MN发起SN修改过程的原因是终端设备发生过热问题或者终端设备过热问题已经解决，或者用于指示MN发送S-Node modification request消息或者MN发起SN修改过程的原因是终端设备期望降低功耗或者不再期望降低功耗。
通过上述技术方案，在双连接的网络架构中，对于主节点设备(MN)和辅节点设备(SN)，当终端设备发生过热问题时或者当终端设备期望降低功耗时，MN可以向SN通知终端设备发生过热问题或者终端设备期望降低功耗，或者向SN提供MN确定的用于解决终端设备过热问题或者降低终端设备功耗的辅助信息。该辅助信息可以包括MN指示SN可以或者被允许为终端设备配置的通信参数，或者该辅助信息可以包括终端设备上报的用于解决过热问题或者用于降低功耗的通信参数。使得SN可以从MN提供的辅助信息中，选择用于解决终端设备过热问题或者降低终端设备功耗的通信参数，从而为终端设备配置通信参数。当终端设备工作于MR-DC场景下发生过热问题或者终端设备期望降低功耗时，能够让SN为终端设备配置合适最大MIMO layer数、最大SCell数目或者最大聚合带宽以帮助终端设备缓解过热问题或者帮助终端设备降低功耗。当终端设备过热问题解决或者终端设备不再期望降低功耗时，MN还可以向SN通知终端设备过热问题已经解决或者终端设备不再期望降低功耗，并可以恢复终端设备所支持的最大能力的配置或者终端设备原来和MN、SN连接时的配置。
以上针对MN和SN组成的接入网架构，介绍了本申请提供的一种传输信息的方法，在5G中，引入了一种新的接入网架构，把5G的基站(NR gNB)分为中心单元(central unit，CU)和分布单元(distributed unit，DU)。接入网的控制面协议层(radio resource control，RRC)位于中心单元。接入网的用户面协议层中分组数据汇聚协议(packet data convergence protocol，PDCP)层位于中心单元，其余协议层包括无线链路控制(radio link control，RLC)层，媒体接入控制(media access control，MAC)层和物理层(physical layer，Phy)位于分布单元。其网络架构如图5中的(a)图所示。
对于图5中的(b)图所示CU-DU的架构下，终端设备和主节点设备(主基站)的通信过程中，终端设备需要的通信参数可以由CU进行配置，由DU进行调度；或者由DU进行配置。
当终端设备在CU-DU架构的接入网下发生过热问题后，终端设备可以向主基站上报带有过热辅助信元的过热消息，即终端设备可以向CU上报带有过热辅助信元的过热消息。当CU收到终端设备上报的终端设备所支持的临时配置的最大MIMO layer数后，会有以下两种可能的情况：
(1)如果由CU为终端设备配置在每个服务小区上的最大MIMO layer数，那么CU重配了最大MIMO layer数，DU也需要知道，否则DU在为终端设备调度数据传输时会出现问题。
(2)如果由DU为终端设备配置在每个服务小区上的所用的最大MIMO layer数，那么为了解决终端设备的过热问题，需要让DU知道终端设备所支持的临时配置的最大MIMO layer数。
综上所述，无论是上述哪种情况，因为终端设备上报的过热信息是RRC消息，该、因为DU没有对应的RRC层，无法获取该过热消息中包括的信息内容，使得DU都无法获取到对应的信息。使得DU不能终端设备所期望的最大MIMO layer数，为终端设备配置，不能解决终端设备的过热问题。
为了解决终端设备的过热问题，本申请还提出一种传输信息的方法，通过在网络设备的CU和DU之间的信息交互，使得DU能够知道终端设备发生过热问题，进而为终端设备配置合适的最大MIMO layer，或者能够按照终端设备支持的最大MIMO layer数来为终端设备调度上行和/或下行的数据传输。
图6是本申请实施例提供的一例传输信息的方法600的示意性交互图。下面，对方法600的每个步骤进行详细说明。
应理解，在本申请实施例中，以终端设备、CU和DU作为执行方法600的执行主体为例，对方法600进行说明。作为示例而非限定，执行方法600的执行主体也可以是应用于终端设备的芯片和应用于CU、DU的芯片。
S601，终端设备确定出现过热。
S602，终端设备向CU发送第一消息，所述第一消息包括过热辅助信息，所述过热辅助信息用于指示所述终端设备是否过热。
可选地，该第一消息是终端设备向CU发送的过热消息(带有过热辅助信息的UE assistance information)。当该过热消息中包括过热辅助信息，过热辅助信息可以包括该终端设备期望临时配置的最大MIMO layer数，该最大MIMO layer数是可以解决终端设备过热问题的参数配置。
应理解，终端设备在和基站建立连接时，会向基站上报正常状态下的最大能力，终端设备在过热情况下上报的通信参数小于正常状态下的最大能力对应的通信参数。
例如，终端设备正常状态下上报的支持的最大MIMO layer数为4层，即CU为终端设备配置的最大MIMO layer数都为4层。当终端设备出现过热时，终端设备向CU发送的过热辅助信息中指示当前终端设备期望的临时配置最大MIMO layer数为2层，这样当CU为终端设备重配了最大MIMO layer数为2后，DU也需要知道，才可以解决终端设备的过热问题。
S603，CU接收终端设备发送的第一消息，根据所述第一消息包括的过热辅助信息，确定第二消息。
应理解，该第二消息用于指示DU调整为所述终端设备配置的通信参数，该通信参数包括上行和/或下行MIMO layer数。
S604，CU向DU发送第二消息。相应地，DU接收CU发送的第二消息。
S605，DU根据CU发送的第二消息确定可以为所述终端设备配置或者调度的最大MIMO layer数，并根据该最大MIMO layer数确定第三消息。
S606，SN向MN发送所述第三消息。相应地，CU接收DU发送的第三消息，所述第三消息是所述第二消息的响应消息。
应理解，在S602中，介绍了当终端设备出现过热时，会在过热辅助信息中携带当前支持的通信参数。当终端设备过热问题解决时，该过热辅助信息中不包括任何信息。因此，CU可以根据过热辅助信息中是否携带信息来判断终端设备当前是否过热。
在一种可能的实现方式中，该第一消息是终端设备上下文修改请求消息(UE context modification request)，所述第二消息是终端设备上下文修改响应消息(UE context modification response)。
在一种可能的实现方式中，该第二消息包括所述过热辅助信息，所述过热辅助信息中包括第一信息，所述第一信息用于指示所述终端设备期望配置的不同频率范围的服务小区上的最大上行MIMO layer数和/或最大下行MIMO layer数。示例性的，终端设备在不过热的情况下，最大可支持DU配置的最大MIMO layer数为8，当终端设备发生过热问题时，在过热辅助信息中上向CU上报，当前在FR1上的服务小区上，终端设备所期望配置的MIMO layer数为4。当CU收到终端设备上报的带有终端设备过热消息后，CU发起终端设备上下文修改过程。CU向DU发送UE context modification request消息。
如果终端设备上报的过热辅助信息中包含终端设备期望的FR1上的服务小区上临时配置的最大MIMO layer数，并且CU确定为终端设备重配终端设备在FR1上的服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数，CU在UE context modification request消息中包含为终端设备配置的在FR1上的每个服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数。
如果终端设备上报的过热辅助信息中包含终端设备期望的FR2上的服务小区上临时配置的最大 MIMO layer数，并且CU确定为终端设备重配终端设备在FR2上的服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数，CU在UE context modification request消息中包含为终端设备配置的在FR2上的每个服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数。
如果终端设备上报的过热辅助信息中不包含任何信息，并且CU确定为终端设备重配终端设备在FR1上的服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数，CU在UE context modification request消息中包含为终端设备配置的在FR1上的每个服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数。
如果终端设备上报的过热辅助信息中不包含任何信息，并且CU确定为终端设备重配终端设备在FR2上的服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数，CU在UE context modification request消息中包含为终端设备配置的在FR2上的每个服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数。
可选的，上述信息可以包含在CU向DU发送的RRC信元(RRC information)中。其中，CU需要为终端设备重配在每个服务小区上所用的上行最大MIMO layer数和/或下行最大MIMO layer数的原因或者触发条件可以包括：
(1)CU收到UE上报的带有过热辅助信息的过热消息；
(2)在EN-DC配置下，CU收到MN发送的终端设备过热的辅助信息。
应理解，以上介绍的终端设备过热辅助信息可以承载在上下文修改请求消息中新增加的信元上，本申请对此不做限定。
还应理解，在这种情况下，CU发送给DU的最大MIMO layer数就为终端设备上报的最大MIMO layer数。因此，该第二消息就可以包含终端设备上报的所期望配置的MIMO layer数，CU和DU为终端设备配置的最大MIMO layer相等。此时，第三消息可以包括该最大MIMO layer数，也可以不包括该最大MIMO layer数，本申请对此不做限定。
在一种可能的实现方式中，该所述第二消息包括所述过热辅助信息，所述过热辅助信息中不包括任何信息。在一种可能的实现方式中，该第二消息中包括第二信息，所述第二信息用于指示所述分布单元为所述终端设备配置的不同频率范围的服务小区上的最大上行MIMO layer数和/或最大下行MIMO layer数。
当CU收到终端设备上报的过热消息后，CU发起终端设备上下文修改过程。CU向DU发送UE context modification request消息。
如果终端设备上报的过热辅助信息中包含终端设备期望的FR1上的服务小区上临时配置的最大MIMO layer数，在UE context modification request消息中包含以下信息：
(1)终端设备期望的FR1上的服务小区上临时配置的最大上行MIMO layer数；其中，第一值用于指示终端设备在FR1上的服务小区上可以被配置的上行最大MIMO layer数没有限制，即和终端设备在终端设备能力上报消息中上报的终端设备能支持的最大上行MIMO layer数相同。
(2)终端设备prefer的FR1上的服务小区上临时配置的最大下行MIMO layer数；其中，第一值用于指示终端设备在FR1上的服务小区上可以被配置的下行最大MIMO layer数没有限制，即和终端设备在终端设备能力上报消息中上报的终端设备能支持的最大上行MIMO layer数相同。
可选地，以上列举的第二信息的取值为终端设备在过热辅助信息上报的对应的值。
如果终端设备上报的过热辅助信息中包含终端设备prefer的FR2上的服务小区上临时配置的最大MIMO layer数，在UE context modification request消息中包含以下信息：
(1)终端设备prefer的FR2上的服务小区上临时配置的最大上行MIMO layer数；其中，第一值用于指示终端设备在FR2上的服务小区上可以被配置的上行最大MIMO layer数没有限制，即和终端设备在终端设备能力上报消息中上报的终端设备能支持的最大上行MIMO layer数相同。
(2)终端设备prefer的FR2上的服务小区上临时配置的最大下行MIMO layer数；其中，第一值用于指示终端设备在FR2上的服务小区上可以被配置的下行最大MIMO layer数没有限制，即和终端设备在终端设备能力上报消息中上报的终端设备能支持的最大上行MIMO layer数相同。
可选地，以上列举的第二信息的取值为终端设备在过热辅助信息上报的对应的值。
如果终端设备上报的过热辅助信息中不包含任何信息，在UE context modification request消息中包含以上列举的第二信息中的一项或多项中的第一值。
在一种可能的实现方式中，该第二消息中包括第二信息，所述第二信息为终端设备上报的带有过热辅助信息的UE Assistance Information。
当CU收到终端设备上报的带有过热消息后，CU发起终端设备上下文修改过程。CU向DU发送UE context modification request消息。在UE context modification request消息中包含带有过热辅助信息的UE assistance information：
DU接收到CU发送的UE context modification request消息后，给CU回复UE context modification response消息。在UE context modification response消息中包含如下可选的信息：
(1)DU为终端设备配置的每个服务小区上的上行最大MIMO layer数；
(2)DU为终端设备配置的每个服务小区上的下行最大MIMO layer数。
通过上述技术方案，当终端设备在CU-DU网络下发生过热问题时，CU收到终端设备上报的过热消息后，CU可以为终端设备重配最大MIMO layer数。同时，能够让DU知道当前CU为终端设备配置的最大MIMO layer数，从而为终端设备调度的数据传输时，保证为终端设备配置的最大MIMO layer数不超过CU为终端设备配置的最大MIMO layer数，从而解决终端设备的过热问题。
