Description

无线通信方法和装置
本申请要求于2019年9月30日提交的申请号为PCT/CN2019/109641、发明名称为“无线通信方法和装置”的PCT专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种无线通信方法和装置。
背景技术
当前越来越多的终端设备，比如智能手机，能够与两个服务小区同时进行信号传输。例如，支持同时插入两张用户身份模块(subscriber identification module，SIM)卡的终端设备，一张SIM卡用于私人业务，另一张SIM卡用于工作业务；或者一张SIM卡用于数据业务，另一张SIM卡用于语音业务。这种业务模式可以称为双卡模式。双卡可以属于同一移动运营商也可以属于不同移动运营商，或者双卡可以属于同一制式也可以属于不同制式。例如，所述制式可以包括新无线(new radio，NR)、长期演进(long term evolution，LTE)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、码分多址(code division multiple access，CDMA)系统以及全球移动通信(global system for mobile communications，GSM)系统。对于能够与两个服务小区同时进行信号传输的终端设备，当终端设备与两个服务小区均建立了无线资源控制(radio resource control，RRC)连接，现有技术中的数据传输方式可能会造成数据传输的不准确。例如，如果这两个服务小区的频段存在互调失真(intermodulation distortion，IMD)问题，那么当终端设备同时与这两个服务小区进行上行信号传输时，会对终端设备与其中一个服务小区进行的下行信号传输产生影响，导致下行信号的接收灵敏度下降，进而造成数据传输不准确。再例如，终端设备与两个服务小区均建立了RRC连接后，功率余量报告(power headroom report，PHR)发生了变化，但没有重新触发PHR上报，造成接入网设备获得的PHR不再准确，进而造成数据传输不准确。

其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿 戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网(internet of things，IoT)系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。

本申请实施例中的接入网设备可以是用于与终端设备通信的任意一种具有无线收发功能的设备，该接入网设备可以是全球移动通信(global system for mobile communications，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站B(nodeB，NB)，还可以是LTE系统中的演进型基站B(evolved nodeB，eNB或eNodeB)，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，还可以是无线网络控制器(radio network controller，RNC)、基站控制器(base station controller，BSC)、家庭基站(例如，home evolved nodeB，或home nodeB，HNB)、基带单元(baseband unit，BBU)，或者该接入网设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的接入网设备或者未来演进的PLMN网络中的接入网设备等，可以是WLAN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,可以是新型无线系统(new radio，NR)系统中的gNB或传输点(TRP或TP)，或者，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，接入网设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的接入网设备，也可以将CU划分为核心网(core network，CN)中的接入网设备，本申请对此不做限定。
另外，在本申请实施例中，接入网设备为小区提供服务，终端设备通过接入网设备分配的传输资源(例如，频域资源，或者说，频谱资源)与小区进行通信，该小区可以属于 宏基站(例如，宏eNB或宏gNB等)，也可以属于小小区(small cell)对应的基站，这里的小小区可以包括：城市小区(metro cell)、微小区(micro cell)、微微小区(pico cell)、毫微微小区(femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。

另外，本申请实施例的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请实施例中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
需要说明的是，在本申请实施例中，在应用层可以运行多个应用程序，此情况下，执行本申请实施例的通信方法的应用程序与用于控制接收端设备完成所接收到的数据所对应的动作的应用程序可以是不同的应用程序。
在给定时间，接入网设备、终端设备可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
图1示出了本申请实施例提供的一种网络架构的示意图。本申请实施例的通信系统可以包括接入网设备和多个终端设备，并且，多个终端设备之间可以进行设备间通信。如图1所示，本申请实施例的通信系统可以包括基站(base station，BS)和用户设备UE1～UE6，在该通信系统中，基站可以向UE1～UE6中的一个或多个UE发送信息。本申请实施例的通信系统也可以包括用户设备UE4～UE6，在该通信系统中，UE5可以向UE4和UE6中的一个或多个UE发送信息。以上网络架构仅为示意，并非对本申请的限制。
UE的RRC状态包括如下几种。
RRC连接(connected)态：UE与网络建立了RRC连接，可以进行数据传输。
RRC空闲(idle)态：UE没有与网络建立RRC连接，基站没有该UE的上下文。
RRC去激活(inactive)态：UE之前进入了RRC连接态，然后基站释放了RRC连接，但是基站和UE保存了上下文。如果UE需要从RRC去激活态进入RRC连接态，则需要发起RRC连接恢复过程。RRC恢复过程相对于RRC建立过程，时延更短，信令开销更小，但是基站侧需要保存UE的上下文，占用了更多的存储开销。
以下对能够支持两张SIM卡的终端设备进行说明。其中，一个SIM的基站可以理解为该基站服务该SIM对应的通信实体。根据终端设备的收发能力不同，可以将支持双SIM卡的终端设备分为以下三种模式。
单接收单发送(single Rx/Tx)的终端设备，尽管能插入两个SIM卡，但是同一时刻只有一张SIM卡可以使用，即只有一张SIM卡可以接收(receive，Rx)和发送(transmit，Tx)，另一张SIM卡不可用(unused)。
为双接收单发送(dual Rx/single Tx)的终端设备，同一时刻，终端设备可以接收两个SIM卡的数据，但只能发送一个SIM卡的数据。
为双接收双发送(dual Rx/Tx)的终端设备：两个SIM卡对应各自的收发机。终端设备可以同时接收和发送两个SIM卡的数据。
IMD是指两个不同频率的信号，例如，频率为f1的信号和频率为f2的信号，通过非线性放大器相互调制能产生调制信号，该调制信号的频率为m*f1±n*f2。该调制信号是无用信号，如果该调制信号的频率落在接收信号的频段内，会干扰信号的接收，导致接收灵敏度下降。对于能够与两个服务小区同时进行信号传输的终端设备，例如支持双卡模式的终端设备，如果两个SIM卡所使用的频段存在IMD问题，那么当终端设备同时发送两个SIM卡的数据时，两个上行信号会产生调制信号，该调制信号的频率落在终端设备接收其中一个SIM卡的数据所使用的频段内，会对终端接收该SIM卡的数据造成干扰，进而造成数据传输的不准确。
功率余量报告(power headroom report，PHR)是UE向接入网设备提供UE的最大发射功率与预估的进行上行传输所需功率之间的差值。接入网设备可以根据该差值判断分配给UE的资源是否合适。
PHR包括三种类型：
1)类型(Type)1：UE的最大发射功率与预估的物理上行共享信道(physical uplink shared channel，PUSCH)传输所需功率的差值；
2)类型2：UE的最大发射功率与预估的PUSCH和物理上行控制信道(physical uplink control channel，PUCCH)传输所需功率的差值；
3)类型3：UE的最大发射功率与预估的信道探测参考信号(sounding reference signal，SRS)传输所需功率的差值。
PHR的时间触发方式主要包括：
(1)PHR禁止定时器(phr-ProhibitTimer)超时或者已经超时，且路径损耗的变化值超过一定门限值；
(2)PHR周期定时器(phr-PeriodicTimer)超时；
(3)上层配置或者重配置PHR参数(例如，RRC层重新配置了定时器的值)；
(4)一个有上行配置的辅小区被激活；
(5)添加一个辅基站；
(6)phr-ProhibitTimer超时或者已经超时，且MAC层获得一个新的上行传输资源。以类型1的PHR为例，PHR由UE在当前子载波上的最大发射功率和UE预估的上行共享信道传输所需的功率决定。该最大发射功率的取值受最大功率回退(maximum power reduction，MPR)、额外最大功率回退(additional maximum power reduction，A-MPR)以及功率管理最大功率回退(power management maximum power reduction，P-MPR)的影响。MPR和A-MPR是为保证射频功率对电磁环境没有影响，而对最大发射功率进行的松弛。P-MPR可以用来满足电磁能量需求、功率管理需求或处理在向多个接入网设备同时发送信号时带来的不期望的灵敏度下降。需要说明的是，以上所述的最大发射功率的取值与MPR、A-MPR和P-MPR的关系，是用于说明最大发射功率与功率回退、额外功率回退以及由于功率管理而进行的功率回退之间的关系，针对不同的调制方式、不同的资源位置，通信协议会约束MPR和A-MPR，其中，MPR为所述功率回退的最大值，A-MPR为所述额外功率回退的最大值，终端设备在应用功率回退和额外功率回退时不应超过MPR和A-MRP。由于功率管理而进行的功率回退可以用来满足电磁能量需求，以及处理在向多个接入网设备同时发送信号时带来的不期望的灵敏度下降，所述由于功率管理而进行的功率回退的最大值为P-MPR。也就是说，在终端设备的实际应用过程中，所述终端设备在载波f的小区c上配置的最大发射功率是根据实际的功率回退、额外功率回退以及由于功率管理而进行的功率回退来确定的。在本申请中，根据MPR、A-MPR和P-MPR确定最大发射功率，在具体实现中可以理解为根据功率回退实际值、额外功率回退实际值和由于功率管理而进行的功率回退实际值来确定最大发射功率实际值，为了阐述简单，以下均以最大值进行说明。
对于能够与两个服务小区同时进行信号传输的终端设备，例如支持双卡模式的终端设备，当终端设备与两个接入网设备均建立了RRC连接时，由于终端设备与其中一个接入网设备之间通信的功率发生下降，终端设备可以应用功率回退、额外功率回退和由于功率管理而进行的功率回退，以及最大发射功率偏移量(ΔP PowerClass)，也就是说，MPR、A-MPR或P-MPR、ΔP PowerClass等可能发生变化，进而导致终端设备在所述接入网的服务频率上的服务小区上配置的最大发射功率变化，可能使PHR值发生变化，而此时如果没有满足上述PHR上报触发条件，则不会触发PHR上报，导致接入网设备在之前获得的PHR不再准确，进而导致所述接入网设备不能给终端设备调度合适的上行传输资源，降低上行传输的有效性。
当终端设备只有一个RRC连接时，也可能存在此问题，比如终端设备进入双连接的工作模式或者终端设备同时开启了其他信号传输(如，蓝牙，无线保真等)，终端设备的最大发射功率也可能变化，进而PHR值发生变化，而此时如果没有满足上述PHR上报触发条件，则不会触发PHR上报，导致上行传输的有效性降低。
其中，上文所述的ΔP PowerClass是指终端设备的最大发射功率的偏移量，例如，对于功率等级2(power class 2)的终端设备，其最大发射功率可以达到26分贝毫瓦(dBm)，高于一般情况下23dBm的发射功率，为了降低对人体以及空间的辐射影响，一般会限定power class 2终端设备以一定的时间比例工作在26dBm，当基站给所述终端设备调度的上行资源超过所述时间比例时，所述终端设备会应用ΔP PowerClass来降低自己的发射功率，进而影响终端设备在当前服务小区上的最大发射功率，在这种情况下，终端设备的PHR值会发生变化，而此时如果没有满足上述PHR上报触发条件，则不会触发PHR上报，导致接入网设备在之前获得的PHR不准确，进而导致接入网设备不能给终端设备调度合适的 上行传输资源，从而降低上行传输的有效性。需要说明的是，所述ΔP PowerClass的应用不仅限于power class 2终端设备，同样适用于其他场景下最大发射功率的偏移量。下面分别针对终端设备存在IMD问题和PHR上报问题对本申请实施例中的无线通信方法进行说明。
图2示出了本申请一个实施例的通信方法200的示意图。方法200包括步骤S210-S230。
S210，终端设备确定第一服务小区的频段和第二服务小区的频段之间存在互调失真IMD。
第一服务小区的频段与第二服务小区的频段之间存在IMD指的是，终端设备的第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第一下行信号的频段内或者落在第二下行信号的频段内，干扰第一下行信号的接收或干扰第二下行信号的接收。其中，第一上行信号和第一下行信号对应于第一服务小区，第二上行信号和第二下行信号对应于第二服务小区。也就是说第一上行信号和第一下行信号为终端设备与第一服务小区之间传输的信号，第二上行信号和第二下行信号为终端设备与第二服务小区之间传输的信号。
具体地，终端设备确定第一服务小区的频段和第二服务小区的频段之间存在互调失真IMD，可以为终端设备确定第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第一下行信号的频段内或者落在第二下行信号的频段内。
作为示例而非限定，所述第一服务小区可以与终端设备的第一标识关联，所述第二服务小区可以与所述终端设备的第二标识关联。
需要说明的是，在本申请实施例中，所述第一标识和第二标识，可以指核心网为终端设备的用户身份模块(subscriber identification module，SIM)卡1和SIM卡2分配的标识，例如临时移动台标识(temporary mobile subscriber identity，TMSI)或5G网络临时移动台标识(5G temporary mobile subscriber identity，5G-TMSI)，或国际移动用户识别码(international mobile subscriber identity，IMSI)。所述第一标识和第二标识，也可以指接入网为终端设备的SIM卡1和SIM卡2分配的标识，例如小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。对于一个包括两个标识的终端设备，对于网络侧来说，可以看作两个通信实体。
SIM卡可以理解为终端设备接入移动网络的钥匙，为了便于描述，本申请实施例中将SIM卡以及其演进都统称为SIM卡。例如SIM卡可以是全球移动通信系统(global system for mobile communications，GSM)数字移动电话用户的身份识别卡，用于存储用户的身份识别码和密钥，并支持GSM系统对用户的鉴权；又例如，SIM卡也可以是全球用户识别卡(universal subscriber identity module，USIM)，也可以称为升级SIM卡；再例如SIM卡也可以是通用集成电路卡(universal integrated circuit card，UICC)或嵌入式SIM卡(embedded-SIM，eSIM)或软SIM卡等能够标识用户身份的其他形式。本申请实施例以SIM卡进行说明，并不构成对本申请的限制。
例如，第一标识对应SIM卡1，所述第二标识对应SIM卡2，上述第一上行信号和第一下行信号可以理解为终端设备通过SIM卡1与第一服务小区之间进行传输的信号，上述第二上行信号可以理解为终端设备通过SIM卡2与第二服务小区之间进行传输的信号。
本申请实施例中仅以支持双SIM卡的终端设备为例进行说明，本申请实施例的通信方法还适用于支持两个以上SIM卡的终端设备。
需要说明的是，本申请实施例的通信方法也适用于仅支持一个SIM卡的终端设备。也就是说，本申请实施例的通信方法适用于能够同时与至少两个服务小区进行信号传输的终端设备。例如，能够与第一接入网设备以及第二接入网设备进行双连接(dual connection，DC)的终端设备。
本申请实施例中，第一接入网设备是指终端设备的第一服务小区所属的接入网设备，其中，所述终端设备与所述第一接入网设备建立第一RRC连接，当所述终端设备处于RRC空闲态或者RRC去激活态时，仍然驻留在第一接入网设备的服务小区。
第二接入网设备是指终端设备的第二服务小区所属的接入网设备，其中，所述终端设备与所述第二接入网设备建立第二RRC连接，当所述终端设备处于RRC空闲态或者RRC去激活态时，仍然驻留在第二接入网设备的服务小区。
示例性地，终端设备确定第一服务小区的频段与第二服务小区的频段之间存在IMD之后，可以执行步骤S220。
可替换地，当终端设备已经与第一接入网设备建立了第一RRC连接，需要与第二接入网建立或恢复第二RRC连接，且终端设备确定第一服务小区的频段与第二服务小区的频段之间存在IMD，终端设备可以执行步骤S220。
本申请实施例中的“第一RRC连接”指的是终端设备与第一接入网设备建立的RRC连接，“第二RRC连接”指的是终端设备与第二接入网设备建立的RRC连接。
需要说明的是，第一接入网设备和第二接入网设备可以为同一接入网设备，也可以为不同接入网设备。
进一步地，当终端设备正在发送第一上行信号，需要与第二接入网建立或恢复第二RRC连接，且终端设备确定第一服务小区的频段与第二服务小区的频段之间存在IMD，终端设备可以执行步骤S220。也就是说，在该情况下，如果终端设备与第一接入网设备已经建立了第一RRC连接，但当前终端设备没有发送第一上行信号，则终端设备可以不执行步骤S220。
可替换地，当终端设备已经与第一接入网设备建立了第一RRC连接，需要发送第二上行信号，且终端设备确定第一服务小区的频段与第二服务小区的频段之间存在IMD，终端设备可以执行步骤S220。在该情况下，当终端设备已经与第一接入网设备建立了第一RRC连接，同时，终端设备已经与第二接入网设备建立了第二RRC连接。
进一步地，当终端设备正在发送第一上行信号，需要发送第二上行信号，且终端设备确定第一服务小区的频段与第二服务小区的频段之间存在IMD，终端设备可以执行步骤S220。也就是说，在该情况下，如果终端设备与第一接入网设备已经建立了第一RRC连接，但当前终端设备没有发送第一上行信号，则终端设备可以不执行步骤S220。
S220，终端设备向第一接入网设备发送第一消息，所述第一消息用于请求释放(release)第一RRC连接，或用于请求切换(handover)，或用于指示时分多路复用TDM模式，所述TDM模式应用于所述第一服务小区。第一消息用于请求释放(release)第一RRC连接，也可以包括用于请求挂起(suspend)第一RRC连接。本申请实施例中，“切换”指的是服务小区的切换，由第一服务小区切换至目标服务小区。
作为示例而非限定，第一消息可以与终端设备的第一标识关联。例如，第一标识对应SIM卡1，终端设备可以通过SIM卡1向第一接入网设备发送第一消息。
S230，第一接入网设备向终端设备发送第二消息，所述第二消息用于指示所述终端设备释放第一RRC连接，或用于指示切换，或用于响应所述TDM模式。
终端设备可以根据所述第二消息释放第一RRC连接或挂起第一RRC连接或进行切换。
可替换地，第二消息也可以为拒绝消息。第一接入网设备可以拒绝释放第一RRC连接或切换的请求或拒绝所述TDM模式。
根据本申请实施例的方案，终端设备确定存在IMD后可以向接入网设备发送第一消息，以使第一接入网设备释放第一RRC连接或者切换当前服务小区或者确定TMD模式，减少IMD问题产生的影响。
下面以第一服务小区与终端设备的第一标识关联，第二服务小区与终端设备的第二标识关联为例，对方法200分为两种情况(情况1和情况2)进行具体说明。情况1和情况2分别对应下述方法300和方法400。
情况1
图3示出了本申请另一个实施例的无线通信方法300的示意图。方法300包括步骤S310-S330。
S310，终端设备确定第一服务小区的频段和第二服务小区的频段之间存在互调失真IMD。
第一服务小区与终端设备的第一标识关联，第二服务小区与终端设备的第二标识关联。例如，第一标识对应SIM卡1，所述第二标识对应SIM卡2。第一服务小区可以理解为SIM卡1对应的服务小区，第二服务小区可以理解为SIM卡2对应的服务小区。
S320，终端设备向第一接入网设备发送第一消息，所述第一消息用于请求释放(release)第一RRC连接或用于请求切换。
第一消息可以与终端设备的第一标识关联。例如，第一标识对应SIM卡1，终端设备可以通过SIM卡1向第一接入网设备发送第一消息。第一RRC连接可以为终端设备通过SIM卡1与第一接入网设备建立的RRC连接。
第一接入网设备可以根据当前业务传输状态等确定释放第一RRC连接或切换。可替换地，第一接入网设备也可以拒绝第一消息的请求，也就是第一接入网设备可以拒绝释放第一RRC连接或拒绝切换。
进一步地，所述第一消息包括原因值，所述原因值用于指示存在IMD。
具体地，可以通过原因值的字段表示终端设备是否存在IMD。也就是说，终端设备确定第一服务小区的频段和第二服务小区的频段之间存在互调失真IMD之后，可以向第一接入网设备发送原因值，仅通知第一接入网设备该终端设备存在IMD，而无需将第二服务小区的标识(identifier，ID)等信息发送至第一接入网设备。
这样可以辅助第一接入网设备进行决策。第一接入网设备可以根据该原因值确定终端设备存在IMD，进而确定释放第一RRC连接或切换。可替换地，第一接入网设备也可以根据该原因值拒绝第一消息的请求。
进一步地，所述第一消息包括辅助信息，所述辅助信息可以包括第二服务小区的上行频段信息和/或下行频段信息。
应理解，所述辅助信息可以包括第二服务小区的上行频段信息和/或下行频段信息可以为仅发送上行频段信息和/或下行频段信息，而无需发送第二服务小区的ID等信息。
第一接入网设备可以根据第二服务小区的上行频段信息和/或下行频段信息确定所述终端设备的目标服务小区，以使得所述目标服务小区的频段与所述第二服务小区的频段不之间存在IMD，减少IMD问题产生的影响。
S330，第一接入网设备向终端设备发送第二消息，所述第二消息可以用于指示释放所述第一RRC连接或用于指示切换。
进一步地，所述第二消息可以包括指示信息，所述指示信息可以用于指示所述终端设备的目标服务小区信息。
作为示例而非限定，所述第二消息可以用于指示所述终端设备释放所述第一RRC连接。在该情况下，所述第二消息可以为RRC连接释放(RRC Connection Release)消息。所述指示信息可以为重定向指示信息，所述重定向指示信息用于指示该终端设备的目标服务小区信息。终端设备可以根据第二消息释放第一RRC连接，进行小区搜索，尝试驻留到指定的目标服务小区。
作为示例而非限定，所述第二消息可以用于指示所述终端设备切换。在该情况下，所述第二消息可以为切换消息。所述指示信息可以指示切换的目标服务小区信息。终端设备可以根据第二消息切换至目标服务小区。
根据本申请实施例的方案，终端设备确定存在IMD后可以向接入网设备发送第一消息，以使第一接入网设备释放第一RRC连接，避免同时与第一服务小区和第二服务小区进行信号传输，或者终端设备向接入网设备发送第一消息，以使第一接入网设备切换当前服务小区，改变了终端设备与第一接入网设备进行信号传输的频段，减少IMD问题产生的影响。
情况2
图4示出了本申请另一个实施例的无线通信方法400的示意图。方法400包括步骤S410-S430。
S410，确定第一服务小区的频段和第二服务小区的频段之间存在互调失真IMD。
第一服务小区与终端设备的第一标识关联，第二服务小区与终端设备的第二标识关联。例如，第一标识对应SIM卡1，所述第二标识对应SIM卡2。第一服务小区可以理解为SIM卡1对应的服务小区，第二服务小区可以理解为SIM卡2对应的服务小区。
具体地，确定第一服务小区的频段和第二服务小区的频段之间存在互调失真IMD可以分为以下两种场景。
场景1：
终端设备在第一服务小区和第二服务小区均工作在频分双工(frequency division duplexing，FDD)模式。
终端设备确定第一服务小区的频段和第二服务小区的频段之间存在IMD，可以为终端设备确定第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第一下行信号的频段内或者落在第二下行信号的频段内。其中，第一上行信号和第一下行信号对应于第一服务小区，第二上行信号和第二下行信号对应于第二服务小区。
场景2：
终端设备在第一服务小区工作在FDD模式，在第二服务小区工作在时分双工(time division duplexing，TDD)模式。
终端设备确定第一服务小区的频段和第二服务小区的频段之间存在IMD，可以为终端设备确定第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第一下行信号的频段内。其中，第一上行信号和第一下行信号对应于第一服务小区，第二上行信号对应于第二服务小区。
可替换地，终端设备在第一服务小区工作在TDD模式，在第二服务小区工作在FDD模式。
终端设备确定第一服务小区的频段和第二服务小区的频段之间存在IMD，可以为终端设备确定第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第二下行信号的频段内。其中，第一上行信号对应于第一服务小区，第二上行信号和第二下行信号对应于第二服务小区。
S420，向第一接入网设备发送第一消息，所述第一消息用于指示时分多路复用(time-division multiplexing，TDM)模式(pattern)，所述TDM模式应用于所述第一服务小区。
第一消息可以与终端设备的第一标识关联。例如，第一标识对应SIM卡1，终端设备可以通过SIM卡1向第一接入网设备发送第一消息。
具体地，分别针对上述场景1和场景2对该TDM模式进行说明。
场景1：
示例性地，终端设备确定第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第一下行信号的频段内。终端设备可以根据第一服务小区的上行业务模式和下行业务模式确定与第一服务小区进行上行传输和下行传输的TDM模式。例如，所述终端设备以上行业务为主，可以确定上行传输的时间超过下行传输的时间。具体地，TDM模式可以为一段时间内上行传输和下行传输在时间上所占的比例。例如，TDM模式可以指示在一帧内，多少子帧用于下行传输，多少子帧用于上行传输；或者，TDM模式也可以指示一个子帧内，多少符号用于下行传输，多少符号用于上行传输；再或者TDM模式也可以包括上述两种表现形式。具体TDM模式的表现形式本案不做限制。
所述TDM模式用于指示第一上行传输的时段和第一下行传输的时段不同，其中，所述第一上行传输和所述第一下行传输对应于所述第一服务小区。
可替换地，所述TDM模式可以用于指示第一上行传输在第一时段传输以及指示第一下行传输在第二时段传输，其中，所述第一上行传输和所述第一下行传输对应于所述第一服务小区。
这样可以保证终端设备与第一服务小区之间不同时进行上行信号和下行信号的传输，减少IMD问题产生的影响。
示例性地，终端设备确定第一上行信号和第二上行信号同时传输时产生的该调制信号的频率落在第二下行信号的频段内。终端设备可以根据第二服务小区的上行业务模式和下行业务模式确定与第二服务小区进行上行传输和下行传输的TDM模式。
所述TDM模式用于指示第二上行传输的时段和第二下行传输的时段不同，其中，所述第一上行传输和所述第一下行传输对应于所述第二服务小区。
可替换地，所述TDM模式可以用于指示第二上行传输在第一时段传输以及指示第一下行传输在第二时段传输，其中，所述第二上行传输和所述第二下行传输对应于所述第二 服务小区。
也就是说，在该情况下，S420也可以理解为，终端设备向第二接入网设备发送第一消息，所述第一消息用于指示所述终端设备与第二服务小区进行上行传输和下行传输的TDM模式，这样可以保证终端设备与第二服务小区之间不同时进行上行信号和下行信号的传输，减少IMD问题产生的影响。
场景2：
示例性地，终端设备在第一服务小区工作在FDD模式，在第二服务小区工作在TDD模式。
作为示例而非限定，终端设备可以根据第一服务小区的上行业务模式和下行业务模式确定与第一服务小区进行上行传输和下行传输的TDM模式。
具体地，所述TDM模式可以用于指示第一上行传输的时段和第一下行传输的时段不同，其中，所述第一上行传输和所述第一下行传输对应于所述第一服务小区。
可替换地，所述TDM模式可以用于指示第一上行传输在第一时段传输以及指示第一下行传输在第二时段传输，其中，所述第一上行传输和所述第一下行传输对应于所述第一服务小区。
这样可以保证终端设备与第一服务小区之间不同时进行上行信号和下行信号的传输，减少IMD问题产生的影响。
作为示例而非限定，终端设备可以根据第二服务小区的上行传输和下行传输的配比确定与第一服务小区进行上行传输和下行传输的TDM模式，确保第一服务小区的上行传输在时域上不与第二服务小区的上行传输冲突。
具体地，第二上行传输的时段和所述TDM模式指示的第一上行传输的时段不同，或者，第二上行传输的时段和所述TDM模式指示的第一下行传输的时段不同。其中，所述第一上行传输和第一下行传输对应于所述第一服务小区，所述第二上行传输对应于所述第二服务小区。
可替换地，所述TDM模式用于指示第一上行传输或第一下行传输在第三时段传输，第二上行传输在第四时段传输，其中，所述第一上行传输和第一下行传输对应于所述第一服务小区，所述第二上行传输对应于所述第二服务小区。
这样可以保证终端设备不同时发送第一上行信号和第二上行信号或者不同时发送第二上行信号和接收第一下行信号，减少IMD问题产生的影响。
S430，第一接入网设备向终端设备发送第二消息，所述第二消息用于响应所述TDM模式。
响应所述TDM模式可以为同意该TDM模式，也可以为拒绝该TDM模式。
根据本申请实施例的方案，终端设备确定存在IMD后可以向接入网设备发送第一消息，以通知第一接入网设备TDM模式，减少IMD问题产生的影响，进而提升数据传输的准确性。
图5示出了本申请一个实施例的通信方法500的示意图。方法500包括步骤S510-S530。
S510，第一接入网设备向终端设备发送PHR相关参数的阈值信息集合。
具体地，所述阈值信息集合可以由第一接入网设备广播。可替换地，所述阈值信息集合可以由第一接入网设备为终端设备配置，或者所述阈值信息集合可以是预定义的。
所述阈值信息集合以下至少一个：第一阈值、第二阈值、第三阈值、第四阈值、第五阈值和第六阈值。
PHR相关参数可以包括以下至少一个：终端设备的最大发射功率、所述终端设备的最大功率回退MPR、所述终端设备的额外最大功率回退A-MPR、所述终端设备的功率管理最大功率回退P-MPR和所述终端设备的最大发射功率偏移量ΔP PowerClass。
如前所述，PHR为终端设备的最大发射功率与预估的进行上行传输所需功率之间的差值。根据协议规定，终端设备在载波f上的最大发射功率P CMAX,f,c由以下公式确定。
P CMAX_L,f,c≤P CMAX,f,c≤P CMAX_H,f,c
P CMAX_L,f,c＝min{P EMAX,c-ΔT C,c,(P PowerClass-ΔP PowerClass)-max(MPR c+A-MPR c+ΔT IB,c+ΔT C,c+ΔT RxSRS,P-MPR c)}
P CMAX_H,f,c＝min{P EMAX,c,P PowerClass–ΔP PowerClass}
其中，最大发射功率P CMAX,f,c表示在服务小区c的载波f上终端设备根据一定约束配置的最大发射功率。应理解，该最大发射功率适用于PUSCH传输、PUCCH和PUSCH传输以及SRS传输，也就是说本申请实施例中的PHR包括前述三种类型的PHR。P CMAX_L,f,c表示P CMAX,f,c可取的最小值，P CMAX_H,f,c表示P CMAX,f,c可取的最大值，P EMAX,c表示是网络指示的最大发射功率，P PowerClass表示终端设备支持的最大发射功率。MPR c表示针对服务小区c的最大功率回退值，A-MPR c表示针对服务小区c的额外最大功率回退值。MPR c和A-MPR c是针对服务小区c为保证射频功率对电磁环境没有影响，而对最大发射功率进行的松弛。P-MPR c是针对服务小区c的为了满足功率管理功能设置的最大功率回退值。ΔT C,c在一些频带上(例如n1-n5，n7-8，n12，n14，n20，n25，n28，n30，n34，n38-41，n48，n50-51，n65-66，n70-71，n74，n77-84，n86)取值为1.5dB，其他频带上取值为0dB，ΔP PowerClass取值可以为3dB或0dB，ΔT IB,c表示针对服务小区c的额外忍耐度。ΔT RxSRS为针对SRS的发射的参数，对于频带n79，ΔT RxSRS取值可以为4.5dB，对于其他频带中最高频率低于频带n79的最低频率的频带，ΔT RxSRS取值可以为3dB。其中，所述ΔP PowerClass表示所述P PowerClass的偏移量。例如，当power class 2的终端设备确定满足以下三个条件中的至少一个时，可以应用3dB的ΔP PowerClass：
(1)网络设备指示终端设备使用23dBm或者更低的发射功率；
(2)当终端设备向网络设备上报了在一个评估周期内所述终端设备支持传输的上行符号的比例(maxUplinkDutyCycle-PC2-FR1)时；所述终端设备确定在一个评估周期内，接收来自网络设备的上行符号的比例超过所述maxUplinkDutyCycle-PC2-FR1；
(3)当终端设备未向网络设备上报所述maxUplinkDutyCycle-PC2-FR1时；所述终端设备确定在一个评估周期内，接收来自网络设备的上行符号的比例超过50％。
应理解，P-MPR的变化是为了满足电磁法规或射频能量吸收比率(specific absorption rate)的要求，故任何为满足电磁法规或射频能量吸收比率而设置的最大功率回退，均可以理解为P-MPR。
第一阈值与最大发射功率P CMAX,f,c对应，第二阈值与MPR对应，第三阈值与A-MPR对应，第四阈值与MPR和A-MPR对应，第五阈值与P-MPR对应，第六阈值与ΔP PowerClass对应。
步骤S510为可选步骤，方法500也可以直接从步骤S520开始。
S520，终端设备判断PHR相关参数满足预设条件。
在S520之前，方法500还可以包括步骤S521，与第二接入网设备建立或恢复第二 RRC连接。当前终端设备已经与第一接入网设备建立了第一RRC连接。
作为示例而非限定，所述第一接入网设备可以与所述终端设备的第一标识关联，所述第二接入网设备可以与所述终端设备的第二标识关联。例如，第一标识对应SIM卡1，第二标识对应SIM卡2，终端设备可以通过SIM卡1与第一接入网设备建立第一RRC连接，通过SIM卡2与第二接入网设备建立第二RRC连接。
本申请实施例中的“第一RRC连接”指的是终端设备与第一接入网设备建立的RRC连接，“第二RRC连接”指的是终端设备与第二接入网设备建立的RRC连接。
需要说明的是，第一接入网设备和第二接入网设备可以为同一接入网设备，也可以为不同接入网设备。
本申请实施例中仅以支持双SIM卡的终端设备为例进行说明，本申请实施例的通信方法还适用于支持两个以上SIM卡的终端设备。
需要说明的是，本申请实施例的通信方法也适用于仅支持一个SIM卡的终端设备。也就是说，本申请实施例的通信方法适用于能够同时与至少两个接入网设备进行信号传输的终端设备。例如，能够与第一接入网设备以及第二接入网设备进行双连接(dual connection，DC)的终端设备。并且，本申请实施例的通信方法也适用于仅与一个接入网设备进行信号传输的终端设备，如上文所述，当终端设备进入双连接的工作模式或者终端设备同时开启了其他信号传输时，也会产生最大发射功率的变化，而在本申请实施例中，可以通过所述预设条件，提升PHR上报的准确性，进而优化通信资源的分配效率。
进一步地，所述预设条件包括以下至少一个条件，所述至少一个条件之间是和/或的关系：
所述最大发射功率的变化值大于或等于第一阈值；
所述MPR的变化值大于或等于第二阈值；
所述A-MPR的变化值大于或等于第三阈值；
所述MPR的变化值与所述A-MPR的变化值的和大于或等于第四阈值；
所述P-MPR的变化值大于或等于第五阈值；
所述ΔP PowerClass的变化值大于或等于第六阈值；
终端设备开始应用所述ΔP PowerClass；
终端设备停止应用所述ΔP PowerClass。
所述预设条件可以是预定义的条件。需要说明的是，所述ΔP PowerClass的变化值大于或等于第六阈值是指：由于最大发射功率偏移量变化而导致的功率回退的变化量超过第六阈值，如S510中的公式所示，当ΔP PowerClass变化时，P CMAX_L,f,c和P CMAX_H,f,c也发生变化，进而导致P CMAX,f,c发生变化，也就是说，当终端设备应用最大发射功率偏移量来调整最大发射功率时，通过应用不同的最大发射功率偏移量ΔP PowerClass，可以得到不同的最大发射功率P CMAX,f,c的回退，如果最大发射功率偏移量变化量超过第六阈值，或者，最大发射功率回退的变化量超过第六阈值，则终端设备上报PHR，例如，终端设备处于最大发射功率26dBm达到一定时长后，通过应用3dBm的最大发射功率偏移量，将最大发射功率回退为23dBm，此时的最大发射功率偏移量变化量为3dBm，最大发射功率回退的变化量为3dBm，如果3dBm超过第六阈值，则终端设备上报PHR。所述终端设备开始应用所述ΔP PowerClass是指：终端设备应用最大发射功率偏移量来实现功率回退，例如，power class 2的终端设 备在满足S510中所述的三个条件时会应用3dB的ΔP PowerClass；相应的，当终端设备确定不再满足所述三个条件时，停止应用所述ΔP PowerClass，所述终端设备停止应用所述ΔP PowerClass也可以理解为，所述ΔP PowerClass为0dB。本申请实施例不限定应用所述ΔP PowerClass时，终端设备调整的功率大小。例如，对于power class 2的终端设备，确定在一个评估周期内传输的上行符号比例超过50％或maxUplinkDutyCycle-PC2-FR1，终端设备将最大发射功率偏移量从0dB调整至3dB，也就是说，开始应用所述ΔP PowerClass；或者，确定在一个评估周期内传输的上行符号比例低于50％或maxUplinkDutyCycle-PC2-FR1，终端设备将最大发射功率偏移量从3dB调整至0dB，也就是说，停止应用所述ΔP PowerClass。通过在ΔP PowerClass的变化值大于或等于第六阈值时，或者，在终端设备开始和/或停止应用所述ΔP PowerClass时上报PHR，可以避免在ΔP PowerClass变化导致的最大发射功率变化时遗漏上报PHR，进而使网络设备更准确的分配通信资源，提高上行传输的效率。
示例性地，在终端设备已经与第一接入网设备建立了第一RRC连接的情况下，终端设备建立或恢复第二RRC连接。上述变化值可以理解为，在第一接入网设备建立了第一RRC连接的情况下，终端设备建立或恢复第二RRC连接之前的相关参数值与建立或恢复第二RRC连接之后的相关参数值之间的差值。
进一步地，在终端设备正在发送第一上行信号的情况下，终端设备与第二接入网设备建立或恢复第二RRC连接。上述变化值可以为在终端设备正在发送第一上行信号的情况下，终端设备建立或恢复第二RRC连接之前的相关参数值与建立或恢复第二RRC连接之后的相关参数值之间的差值。
可替换地，在终端设备已经与第一接入网设备建立了第一RRC连接的情况下，终端设备发送第二上行信号。在该情况下，终端设备已经与第二接入网设备建立了第二RRC连接。上述变化值可以理解为，在终端设备已经与第一接入网设备建立了第一RRC连接，已经与第二接入网设备建立了第二RRC连接的情况下，终端设备发送第二上行信号之前的相关参数值与发送第二上行信号时的相关参数值之间的差值。
进一步地，在终端设备正在发送第一上行信号的情况下，终端设备发送第二上行信号。在该情况下，终端设备已经与第一接入网设备建立了第一RRC连接，与第二接入网设备建立了第二RRC连接。上述变化值可以理解为，终端设备正在发送第一上行信号，终端设备已经与第二接入网设备建立了第二RRC连接的情况下，终端设备发送第二上行信号之前的相关参数值与发送第二上行信号时的相关参数值之间的差值。
其中，上述第一上行信号对应于第一服务小区，上述第二上行信号对应于第二服务小区。所述第一阈值至第五阈值中的一个或多个可以为协议规定的值。在一种可能的设计中，终端设备判断PHR相关参数满足预设条件后，还需要确定满足第一时长后才触发PHR上报，所述第一时长为预定义的或者预配置的，所述第一时长用于限定上报PHR的周期，以避免终端设备频繁上报，进而节省通信资源。例如，所述第一时长是通过phr-ProhibitTimer配置的，在终端设备判断PHR相关参数满足预设条件后，还需要确定phr-ProhibitTimer超时或者已经超时，才上报PHR，通过复用phr-ProhibitTimer参数，网络设备可以不消耗额外的信令就能避免PHR的频繁上报。又例如，通过另外的第一时长指示信息来指示终端设备上报PHR的周期，与现有的phr-ProhibitTimer参数区别应用，从而实现更加灵活的PHR上报周期控制。
S530，触发PHR上报至第一接入网设备。
进一步地，在终端设备已经与第一接入网设备建立了第一RRC连接，且已经与第二接入网设备建立了第二RRC连接的情况下，若S520中，终端设备判断PHR相关参数满足预设条件，可以触发PHR上报至第一接入网设备和第二接入网设备。
示例性地，在终端设备已经与第一接入网设备建立了第一RRC连接的情况下，终端设备发送第二上行信号。在该情况下，终端设备已经与第二接入网设备建立了第二RRC连接。当终端设备判断PHR相关参数满足预设条件，可以触发PHR上报至第一接入网设备和第二接入网设备。
进一步地，在终端设备正在发送第一上行信号的情况下，终端设备发送第二上行信号。在该情况下，终端设备已经与第一接入网设备建立了第一RRC连接，与第二接入网设备建立了第二RRC连接。当终端设备判断PHR相关参数满足预设条件，可以触发PHR上报至第一接入网设备和第二接入网设备。在一种可能的设计中，终端设备上报的PHR中包括所述终端设备在载波f上的服务小区c的最大发射功率P CMAX,f,c和/或所述终端设备在载波f上的服务小区c的功率余量，通过PHR上报，网络设备可以确定所述终端设备在载波f的服务小区c上可以使用的功率情况，从而更加准确的分配传输资源，提高资源利用率和上行传输的效率。
根据本申请实施例的方案，当PHR发生变化，例如由终端设备建立两个RRC连接引起的PHR变化，可以根据上述PHR上报触发条件，触发PHR上报，通知接入网设备变化后更准确的PHR值，以使接入网设备能够准确判断分配给终端设备的资源是否合适，保证了数据传输的准确性。
