Description

一种消息处理方法及装置

技术领域
本申请实施例涉及通信技术领域，尤其涉及一种消息处理方法及装置。
背景技术
在第五代移动网络(5th generation mobile networks，5G)通信中，终端可以在不同小区上与网络设备进行通信。示例性的，网络设备可以为终端配置多个小区(cell)，同时在每个小区中配置一个或多个带宽组(bandwidth part，BWP)，以便终端通过不同的BWP与网络设备进行通信。
目前，终端可以将成员载波(component carrier，CC)和BWP对应的直流(direct current，DC)位置上报给网络设备，以便网络设备根据该DC位置(DC location)，优化通过该BWP与终端进行的数据传输。具体的，当网络设备为终端配置了多个小区，每个小区都配置有多个BWP时，对于该多个小区中的每个小区，终端可以将该小区的多个BWP中任意BWP对应的DC位置上报给网络设备。以便在通信过程中，网络设备可以根据被激活的BWP确定对应的DC位置，优化对应的数据传输。进一步的，在带内(intra-band)上行载波聚合(carrier aggregation，CA)下，对于该组合中的两个CC，终端可以将这两个CC对应的多个BWP组合中任意BWP组合对应的DC位置上报给网络设备,以便在通信过程中，网络设备可以根据被激活的BWP组合，即每个CC中激活的一个BWP组成的BWP对(BWP pair)来确定对应的DC位置，优化对应的数据传输。
但是，在载波聚合(carrier aggregation，CA)通信场景下，当终端具有多个通道，且关联DC位置的CC数量超过两个CC时，网络设备无法知晓该多个通道与DC位置之间的关系，从而无法知晓每个通道在当前通信中的DC位置，进而也就无法据此进行数据传输的优化。

需要说明的是，本申请中，“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他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。
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描述。
在通信过程中，网络设备可以通过终端上报的直流(direct current，DC)位置，确定通信过程中，对应小区(cell)载波的本振泄露(local oscillator leakage，lo leakage)在频域上的位置，进而据此对本振泄露位置进行相应的处理，例如对本振泄露位置对应频率传输的数据块进行恢复或选择性丢弃，以便提升在该小区载波上数据传输的质量。
在长期演进(long term evolution，LTE)系统中，一般默认DC位置处于对应小区载波的频域中心处的资源粒子(resource element，RE)上，也就是说，小区对应的DC位置对应频率一般都处于对应小区载波对应频域带宽的中心频点上。网络设备可以根据小区载波对应的频域带宽确定DC位置，并对其进行针对性的处理。
与LTE系统不同的是，在第五代移动通信技术(5th generation mobile networks，5G)系统中，DC位置对应的频率可以被设置在对应小区载波的频域带宽上的任意位置，因此，网络设备就需要通过终端上报DC位置，来确定对应小区载波的本振泄露位置，以便据此进行相应的处理，提升数据传输的质量。
需要说明的是，在5G系统中，可以通过将小区载波对应的频域带宽(或称为系统工作带宽(carrier bandwidth，CBW))划分为多个不同的带宽组(bandwidth part，BWP)进行通信，不同BWP在小区载波上的位置可以是灵活配置的。每个BWP都可以对应一个DC位置。因此，在终端向网络设备上报DC位置时，需要将每个BWP对应的DC位置都上报给网络设备，以便网络设备根据当前通信过程中激活的BWP，确定当前通信的DC位置。本申请实施例中，可以将小区载波上的BWP称为小区的BWP。
示例性的，网络设备可以向终端发送指示消息，用于指示终端上报网络设备为终端配置的BWP的DC位置。以网络设备为终端配置了2个小区(如cell 1以及cell 2)，每个小区中包括2个BWP(如cell 1包括BWP11和BWP12，cell 2包括BWP21和BWP22)为例。在接收到网络设备发送的上报DC位置的指示消息后，终端可以将每个BWP的DC位置分别上报给网络设备。例如，将BWP11对应的DC位置DC11、BWP12对应的DC位置DC12、BWP21对应的DC位置DC21和BWP22对应的DC位置DC22，上报给网络设 备。以便在激活一个对应的BWP时，网络设备可以根据对应的DC位置确定当前通信本振泄露的频率位置，进而据此进行数据传输的优化。
此外，在5G系统的数据传输中，还存在大量的在同时激活多个BWP进行数据传输的场景。例如，在载波聚合(carrier aggregation，CA)通信场景下，如带内CA(intra band CA)通信或带间CA(inter band CA)通信，在网络设备为终端配置的多个小区中，可能会存在两个或多个小区中都各自可以存在一个被激活的BWP。而作为一个整体的传输过程，一个CA通信过程存在只对应一个本振泄露位置的情况，也就只对应一个DC位置。此时，终端可以将网络设备配置的多个成员载波(component carrier，CC)中，任意两个CC组成的CC对(pair)中任意两个BWP对应的DC位置进行上报，任意两个BWP位于分别位于CC对中的不同CC。以便在通信过程中，网络设备可以根据被激活的BWP确定对应的DC位置，优化对应的数据传输。
但是，当终端具有至少两个通道且聚合载波数为至少三个CC时，网络设备无法知晓该多个通道与CC的映射关系，从而无法知晓每个通道对应的DC位置，从而无法知晓每个通道在当前通信中的DC位置，进而也就无法据此进行数据传输的优化。为了解决上述问题，本申请实施例提供一种消息处理方法，能够使得网络设备知晓至少两个通道中每个通道对应的DC位置，进而能够据此对该通信进行主动管理，例如，对该DC位置对应的数据块进行相应处理。
以下结合附图对本申请实施例提供的消息处理方法进行详细说明。
请参考图1，为本申请实施例提供的一种通信系统100的组成示意图。如图1所示，该通信系统100可以包括终端110以及网络设备120。在该通信系统100中，还可以包括除110之外的其他终端，例如，该通信系统100中还可以包括如图1所示的终端130。本申请实施例对于通信系统100中包括的终端的数量不做限制。示例性的，本申请实施例中的终端(也可以称为终端设备)可以是用户设备(user equipment，UE)、手机、平板电脑、桌面型、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)、增强现实(augmented reality，AR)\虚拟现实(virtual reality，VR)设备、媒体播放器等能够支持5G通信的电子设备，本申请实施例对该设备的具体形态不作特殊限制。
在该通信系统100中，网络设备120可以为5G基站。应当理解的是，在另一些实施例中，该网络设备120也可以是能够为5G通信提供支持的第三代移动通信技术(3rd-Generation，3G)或第四代移动通信技术(the 4th generation mobile communication technology，4G)基站，或其他通信设备。示例性的，当该网络设备120为5G基站时，能够提供5G新空口(new radio，NR)用于与其他设备(如终端110和/或终端130)进行5G通信。在一些实施例中，该网络设备120可以包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、编码器、解复用器或天线等)。

需要说明的是，该通信系统100可以是公共陆地移动网络(Public Land Mobile Network，PLMN)或者设备与设备(device-to-device，D2D)网络或者机器与机器(machine to machine，M2M)网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。

作为一种示例，终端可以依照约定的结构，在第一消息中发送该终端的DC位置。例如，以下示出了一种第一消息的结构示意。

在一种可能的实现方式中，第一消息还用于指示该终端的DC位置所在CC的小区标识。也即是，对于第一消息所指示的多个DC位置中的每个DC位置，第一消息还用于指示该DC位置所在CC的小区标识。
可选的，该M个通道可以是按照该终端中包括的功率放大器(power amplifier，PA) 的数量划分的，即该M个通道中的每个通道对应一个PA。
或者，该M个通道可以是按照该终端的间隔等级(separation class)的数量划分的，即该M个通道中的每个通道对应该终端的一个间隔等级。比如，该终端的射频前端部分采用了多PA的相控阵，或者该终端用于毫米波通信时，该M个通道可以是按照该终端的间隔等级的数量划分的。
进一步的，对于毫米波的带间(inter-band)CA通信，该终端还可以向网络设备上报CA对应的多个CC的波束管理信息，以使网络设备根据该终端上报的波束管理信息通知该终端如何上报DC位置。可选的，当该终端向网络设备上报的波束管理信息为独立波束管理(independent beam management，IBM)信息时，网络设备可以指示该终端按时上述第一消息的方式上报DC位置；当该终端向网络设备上报的波束管理信息为公共波束管理(common beam management，CBM)信息时，网络设备可以指示该终端按带内载波聚合(intra-band CA)的方式上报DC位置。
示例性的，在该终端向网络设备发送第一消息之前，该方法还可以包括：该终端还可以向该网络设备发送第二消息，第二消息用于指示该终端的聚合载波对应的多个CC的波束管理模式信息；当该网络设备接收到第二消息时，该网络设备可以向该终端发送第三消息，第三消息用于指示该终端发送第一消息。这样，当该终端接收到来自该网络设备的第三消息时，该终端可以通过上述S201向该网络设备发送第一消息，以将该终端的DC位置上报给该网络设备。
S202：该网络设备接收第一消息。需要说明的是，S202中的第一消息的相关描述可以参考上述S201中的描述，本申请实施例在此不再赘述。
S203：该网络设备根据第一消息，确定该M个通道中每个通道的当前通信的DC位置。
具体的，对于M个通道中的每个通道，若该通道对应只有一个CC，该网络设备可以将该CC的多个BWP中处于激活状态的BWP的DC位置确定为该通道当前通信的DC位置。若该通道对应多个CC中被激活CC包括至少两个CC，且载波频点最低的第一CC和载波频点最高的第二CC组成第一CC对，第一CC对中当前处于被激活状态的BWP组成第一BWP组合，则该网络设备可以从该通道对应的多个DC位置中查询获取第一CC对中第一BWP组合对应的DC位置作为该通道当前通信的DC位置。网络设备可以根据以上规则确定该M个通道中每个通道上当前通信的DC位置。
在一种实施例中，对于M个通道中的每个通道，若该通道对应只有一个CC，网络设备将该CC的多个BWP中处于激活状态的BWP的DC位置确定为该通道上当前通信的DC位置，或根据上报的激活BWP对应的DC位置来确定该通道上当前通信的DC位置；若该通道对应多个CC中被激活CC包括至少两个CC，则网络设备将该多个激活CC上配置的BWP组合中处于激活状态的BWP的DC位置确定为该通道上当前通信的DC位置；或者，若该通道对应多个CC中被激活CC包括至少两个CC，则网络设备根据上报的激活BWP对应的DC位置来确定该通道上的DC位置。
在本申请实施例提供的方法，当该终端具有M个通道且对应N个CC时，该终端可以通过第一消息将该M个通道中每个通道对应的CC，该M个通道中的某一通道对应只有一个CC时该CC中的BWP对应的DC位置，以及该M个通道中的某一通道对应多个CC时该多个CC中任意两个CC组成的CC对中任意两个BWP对应的DC位置上报给网络设 备，以使网络设备可以知悉该M个通道中每个通道的DC位置，进而从该M个通道的DC位置中查询确定该终端当前通信所使用的通道的DC位置，从而据此进行数据传输的优化。

示例性的，若该终端不支持第一能力，则该终端在向网络设备发送用于指示该终端不支持第一能力的第一消息之后，该终端可以直接确定向该网络设备上报DC位置。
进一步的，在上述S302或S303之后，若该终端支持第一能力且确定不向该网络设备 上报DC位置，该终端可以向该网络设备发送上行数据之前，通过第一能力(即本振泄露自校准能力)对该上行数据进行优化处理后，再将该上行数据发送给该网络设备。若该终端确定向该网络设备上报DC位置，则该终端可以根据该网络设备的指示或者自身支持的DC位置上报的能力向该网络设备上报DC位置。相应的，如图8所示，该方法还可以包括：S304-S305；和/或S306-S307。
S304：该终端向该网络设备发送第三消息，第三消息用于指示该终端是否支持第二能力。第二能力为支持单载波或聚合载波的增强DC位置上报的能力，支持单载波下的增强DC位置上报和支持聚合载波的增强DC位置上报可以携带在同一个上报信息中，也可以携带在不同的上报信息中。相应的，该网络设备接收第三消息。

具体的，当该终端支持单载波的增强DC位置上报和聚合载波的增强DC位置上报时，该终端向该网络设备发送的第三消息可用于指示该终端支持第二能力；当该终端不支持单载波的增强DC位置上报和聚合载波的增强DC位置上报时，该终端向该网络设备发送的第三消息可用于指示该终端不支持第二能力。
S305：当该终端确定向该网络设备上报DC位置时，该终端向该网络设备发送第四消息，第四消息用于指示该终端的DC位置。相应的，该网络设备可以接收第四消息。
在一种示例中，若该终端不支持第二能力，则该终端可以按照单载波的DC位置上报方式将该终端的DC位置上报给该网络设备。其中，上报的DC位置可以包括该单载波的多个BWP中每个BWP的DC位置。
在另一种示例中，若该终端为聚合载波通信且该终端支持第二能力，则该终端可以按照增强的单载波和聚合载波的DC位置上报方式将该终端的DC位置上报给该网络设备。其中，该DC位置包括聚合载波的多个CC中，任意两个CC组成的CC对中任意两个BWP对应的DC位置，任意两个BWP分别位于CC对中的不同CC。示例性的，该终端可以按照上述图2所提供的方法，将该终端的M个通道对应N个CC时每个通道的DC位置上报给该网络设备。

具体的，当该终端支持上述带内载波聚合的DC位置上报时，该终端向该网络设备发送的第五消息用于指示该终端支持第三能力；当该终端不支持上述带内载波聚合的DC位置上报时，该终端向该网络设备发送的第五消息用于指示该终端不支持第三能力。

进一步的，当该终端同时支持不同能力的DC位置上报方式时，该终端在向该网络设备上报自身支持的能力之后，该网络设备可以向该终端发送第三指示消息，第三指示消息用于指该终端上报DC位置的方式，这样当该终端接收到第三指示消息时，该终端可以按照第三指示消息所指示的方式上报DC位置。

在本申请实施例提供的方法中，当该终端支持本振泄露自校准能力，和/或支持不同能力的DC位置上报时，该终端可以根据自身支持的能力或者网络设备的指示，对应确定是否向网络设备上报DC位置，并在确定上报DC位置时按照相应的上报方式完成DC位置的上报，从而解决了该终端支持本振泄露自校准能力和/或支持DC位置上报时如何在网络中共存的问题。
图9为本申请实施例提供的又一种消息处理方法的流程示意图，该方法可以应用于上述图1所示的通信系统100中，用于解决终端上报的DC位置与实际通信的DC位置之间存在偏移的问题，该方法可以包括以下步骤。
S401：终端向网络设备发送更新消息，该更新消息用于更新该终端的DC位置。
其中，该终端与网络设备进行数据传输之前，该终端会将该终端所有可能的DC位置上报给网络设备，该网络设备与该终端建立通信链路且接收到来自该终端的上行数据之后，该网络设备可以从该终端上报的DC位置中获取当前通信的DC位置，并基于该当前通信的DC位置，对该终端的上行数据做数据优化处理。
在该终端与该网络设备进行数据传输的过程中，虽然该终端对应的配置的CC和BWP，以及被激活CC和BWP没有发生切换，但该终端的DC位置会发生偏移的情况，比如，由于该终端的温度或所处工作环境或传输调度的变化，导致该终端的DC位置发生偏移，而 该网络设备接收到的该终端上报的DC位置是不变的，这样该网络设备据此确定的当前通信的DC位置与该终端实际通信的DC位置之间会存在偏移。
基于此，当该终端的DC发生偏移时，该终端可以通过用户设备(user equipment，UE)辅助的信息(UE assistance information，UAI)上报更新后的DC位置消息，用于更新该终端向该网络设备上报的DC位置，比如，该更新消息可以为RRC消息。
需要说明的是，该更新消息可用于更新该终端上报的多个DC位置中的一个或者多个DC位置，其中一个DC位置对应的是当前通信本振泄露的位置，其中多个DC位置是指基于多个配置CC对应的每个CC pair以及对应的所有BWP组合的DC位置，或者多个激活CC对应的每个CC pair以及对应的所有配置的BWP组合的DC位置。关于该更新消息中每个DC位置的更新方式可以与该终端首次上报的DC位置的上报方式相同，本申请实施例对此不作具体限。
可选的，当该终端通过单载波或者带间聚合载波CA的方式上报DC位置时，该更新消息可用于更新以下信息中的一个或者多个：激活的CC所在小区的标识(激活的CC servingcell ID)，激活的BWP的标识(激活的BWP-ID)，DC位置所在资源粒子的位置(该位置的具体范围可以为0-3301)。或者，更新消息可用于更新以下信息中的一个或者多个：激活的CC所在小区的标识(激活的CC servingcell ID)，激活的BWP的标识(激活的BWP-ID)，DC位置相较之前DC位置上报信息的偏移量，偏移量可通过RE数来表达。
或者，当该通过带内聚合载波CA的方式上报DC位置时，该更新消息可用于更新以下信息中的一个或者多个：通道和当前配置的或激活的CC的对应关系；对于每一个通道，该通道对应的当前被激活的CC列表；对于每一个通道，该通道对应的当前被激活的BWP列表；DC位置所在资源粒子的位置(该位置的具体范围可以为0-3301)。或者，更新消息可用于更新以下信息中的一个或者多个：激活的CC所在小区的标识(激活的CC servingcell ID)，激活的BWP的标识(激活的BWP-ID)，DC位置相较之前DC位置上报信息的偏移量，偏移量可通过RE数来表示。
其中，该通道可以是按照该终端中的PA划分的，也可以是按照该终端的间隔等级划分的。
作为一种示例，终端可以依照约定的结构，在更新消息中更新该终端的DC位置。例如，以下示出了一种更新消息的结构示意。
Figure PCTCN2022084210-appb-000002
Figure PCTCN2022084210-appb-000003
对于intra-band CA组合下，上述结构体提供了一种上报当前通信中对应的一个DC位置的更新方法。另一种实现方式中，该终端也可以更新所有配置CC对应的每个CC pair上所有可能BWP组合的DC位置。
S402：网络设备接收该更新消息。需要说明的是，该更新消息与S401中的更新消息一致，具体关于该更新消息的描述可以参见上述S401中的相关描述，本申请实施例在此不再赘述。
S403：该网络设备根据该更新消息，确定该终端当前通信的DC位置。
当该网络设备接收到该更新消息时，该网络设备可以根据该更新消息重新确定该终端当前通信的DC位置，从而基于该当前通信的DC位置对接收到的该终端的上行数据做优化处理。
在本申请实施例提供的方法中，当该终端的DC位置发生偏移时，该终端可以通过向网络设备发送用于更新DC位置的更新消息，以使网络设备可以根据该更新消息确定当前通信的DC位置，从而基于该当前通信的DC位置对数据做优化处理，从而解决终端上报的DC位置与实际通信的DC位置之间存在偏移的问题，同时也避免了该网络设备对错误位置的数据做优化处理而进一步导致数据性能较差的问题。
