Description

用于终端的通信方法及通信装置 技术领域
本申请实施例涉及通信技术领域,尤其涉及用于终端的通信方法及通信装置。
背景技术
现有技术中,终端内部通常可以设置两个或多个用户识别模块(Subscriber Identity Module,SIM)卡,其中,每个SIM卡可对应一个用户。
以双卡双通(dual SIM dual active,DSDA)的终端为例,为保证两个SIM卡对应的两个用户的业务可以同时进行(即业务并发),终端可以向接入设备分别上报两个SIM卡对应的终端能力,这两个SIM卡共享终端的能力规格,两个SIM卡对应的终端能力之和等于终端的能力规格。此后,接入设备基于每个SIM卡对应的终端能力,为每个SIM卡分配相应的资源。因此,两个SIM卡对应的用户可以分别基于接入设备分配的资源,并发执行业务。随着多SIM卡终端的普及,有必要研究如何进一步提升多SIM卡终端的整体性能。

其中,第一接入设备与第二接入设备可以是同一个接入设备,也可以是不同的接入设备。
基于上述方案,单个用户上报的终端能力可以比现有技术更高,并且,上报的第一用户对应的终端能力与上报的第二用户对应的终端能力之和大于终端的能力规格。因此,在单个用户有业务执行的场景下,接入设备可以基于上报的该用户对应更高的终端能力,为该用户的业务分配相应的资源。相较于现有技术,可以提升单个用户有业务执行场景下的终端性能。由于业务并发的场景并不总是存在,因此,采用上述方案有利于提升多SIM卡的终端的整体性能。
作为一种可能的实现方法,所述终端的能力规格包括以下一项或多项:
终端支持进行载波聚合的最大小区数;
终端支持的最大多输入多输出MIMO层数;

此后,当两个用户有业务需要并发执行,本申请实施例可以将其中一个用户对应的终端能力主动进行回退,以减少该用户需占用的终端能力,从而可以为另一用户预留一部分的终端能力,进而实现业务并发。比如,在确定第一用户正在执行第一业务、且第二用户需要发起第二业务;或者,确定第一用户需要发起第一业务、且第二用户正在执行第二业务的情况下,本申请实施例提供以下不同的能力回退方法,包括但不限于:

基于上述方案,通过发送携带秩指示的信道状态信息,从而指示下行MIMO层数与秩指示对应的值相同,也即指示接入设备将下行MIMO层数减少到秩指示对应的值。如此,可以降低第一用户使用的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,进而实现第一业务与第二业务的并发执行。
作为第四种可能的实现方法,使用所述第一用户对应的主小区,但不使用所述第一用户对应的辅小区。
基于上述方案,使用所述第一用户对应的主小区,但不使用所述第一用户对应的辅小区,模拟辅小区没信号的场景,从而触发第一接入设备裁决删除辅小区。如此,可以降低第一用户使用的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,进而实现第一业务与第二业务的并发执行。
作为第五种可能的实现方法,向第一接入设备发送测量报告,所述测量报告不包括所述第一用户对应的辅小区的测量报告。
基于上述方案,终端不向第一接入设备上报第一用户对应的辅小区的测量报告,从而指示第一接入设备不添加辅小区。如此,可以降低第一用户当前支持的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,进而实现第一业务与第二业务的并发执行。
后续,当第一业务或第二业务结束后,可以恢复第一用户使用的终端能力。作为一种可能的实现方法,向所述第一接入设备发送能力恢复消息,所述能力恢复消息用于提高所述第一用户使用的终端能力。
可选的,所述能力恢复消息携带第二辅助信息,所述第二辅助信息携带以下信息中的一项或多项:

具体实施方式
本申请的技术方案主要适用于无线通信系统。该无线通信系统可以遵从第三代合作伙伴计划(third generation partnership project,3GPP)的无线通信标准,也可以遵从其他无线通信标准,例如电气电子工程师学会(Institute of Electrical and Electronics Engineers,IEEE)的802系列(如802.11,802.15,或者802.20)的无线通信标准。
图1为本申请实施例提供的一种无线通信系统的结构示意图。该无线通信系统包括接入设备和一个或多个终端。按照传输方向的不同,从终端到接入设备的传输链路记为上行链路(uplink,UL),从接入设备到终端的传输链路记为下行链路(downlink,DL)。上行链路的数据传输可简记为上行数据传输或上行传输,下行链路的数据传输可简记为下行数据传输或下行传输。
该无线通信系统中,接入设备可通过集成或外接的天线设备,为特定地理区域提供通信覆盖。位于接入设备的通信覆盖范围内的一个或多个终端,均可以接入到接入设备。一个接入设备可以管理一个或多个小区(cell)。每个小区具有一个身份证明(identification),该身份证明也被称为小区标识(cell identity,cell ID)。从无线资源的角度看,一个小区是下行无线资源,以及与其配对的上行无线资源(可选)的组合。
终端和接入设备知晓该无线通信系统预定义的配置,包括系统支持的无线接入技术(radio access technology,RAT)以及系统规定的无线资源配置(比如无线电的频段和载波的基本配置)等。载波是符合系统规定的一段频率范围。这段频率范围可由载波的中心频率(记为载频)和载波的带宽共同确定。这些系统预定义的配置可作为无线通信系统的标准协议的一部分,或者通过终端和接入设备间的交互确定。相关标准协议的内容,可能会预先存储在终端和接入设备的存储器中,或者体现为终端和接入设备的硬件电路或软件代码。
该无线通信系统中,终端和接入设备支持一种或多种相同的RAT,例如新无线(New radio,NR),长期演进(long term evolution,LTE),或未来演进系统的RAT。具体地,终端和接入设备采用相同的空口参数、编码方案和调制方案等,并基于系统规定的无线资源相互通信。
本申请实施例中的终端,是一种具有无线收发功能的设备,可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端、增强现实(augmented reality,AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、用户设备(user equipment,UE)等。
接入设备,是一种为终端提供无线通信功能的设备,接入设备包括但不限于:第五代(5th generation,5G)中的下一代基站(g nodeB,gNB)、演进型节点B(evolved node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如,home evolved nodeB,或home node B,HNB)、基带单元(baseBand unit,BBU)、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、移动交换中心等。
图2为本申请实施例提供的一种无线通信设备的结构示意图。该无线通信设备可以是本申请实施例中的终端或者接入设备。该无线通信设备可包括多个组件,例如:应用子系统,内存(memory),大容量存储器(massive storage),基带子系统,射频集成电路(radio frequency integrated circuit,RFIC),射频前端(radio frequency front end,RFFE)器件,以及天线(antenna,ANT)。这些组件可以通过各种互联总线或其他电连接方式耦合。
图2中,ANT_1表示第一天线,ANT_N表示第N天线,N为大于1的整数。Tx表示发送路径,Rx表示接收路径,不同的数字表示不同的路径。每条路径均可以表示一个信号处理通道。其中,FBRx表示反馈接收路径,PRx表示主接收路径,DRx表示分集接收路 径。HB表示高频,LB表示低频,两者是指频率的相对高低。BB表示基带。应理解,图2中的标记和组件仅为示意目的,仅作为一种可能的实现方式,本申请实施例还包括其他的实现方式。例如,无线通信设备可以包括更多或更少的路径,包括更多或更少的组件。
其中,应用子系统可包括一个或多个处理器。多个处理器可以包括多个相同类型的处理器,也可以包括多种类型的处理器组合。本申请中,处理器可以是通用用途的处理器,也可以是为特定领域设计的处理器。例如,处理器可以是中央处理单元(center processing unit,CPU),数字信号处理器(digital signal processor,DSP),或微控制器(micro control unit,MCU)。处理器也可以是图形处理器(graphics processing unit,GPU)、图像信号处理器(image signal processing,ISP),音频信号处理器(audio signal processor,ASP),以及为人工智能(artificial intelligence,AI)应用专门设计的AI处理器。AI处理器包括但不限于神经网络处理器(neural network processing unit,NPU),张量处理器(tensor processing unit,TPU)以及被称为AI引擎的处理器。
射频集成电路(包括RFIC 1,以及一个或多个可选的RFIC 2)和射频前端器件可以共同组成射频子系统。根据信号的接收或发送路径的不同,射频子系统也可以分为射频接收通道(RF receive path)和射频发射通道(RF transmit path)。其中,射频接收通道可通过天线接收射频信号,对该射频信号进行处理(如放大、滤波和下变频)以得到基带信号,并传递给基带子系统。射频发送通道可接收来自基带子系统的基带信号,对基带信号进行处理(如上变频、放大和滤波)以得到射频信号,并最终通过天线将该射频信号辐射到空间中。射频集成电路可以被称为射频处理芯片或射频芯片。
与射频子系统主要完成射频信号处理类似,基带子系统主要完成对基带信号的处理。基带子系统可以从基带信号中提取有用的信息或数据比特,或者将信息或数据比特转换为待发送的基带信号。这些信息或数据比特可以是表示语音、文本、视频等用户数据或控制信息的数据。例如,基带子系统可以实现诸如调制和解调,编码和解码等信号处理操作。对于不同的无线接入技术,例如5G NR和4G LTE,基带信号处理操作也不完全相同。
与应用子系统类似,基带子系统也可包括一个或多个处理器。此外,基带子系统还可以包括一种或多种硬件加速器(hardware accelerator,HAC)。硬件加速器可用于专门完成一些处理开销较大的子功能,如数据包(data packet)的组装和解析,数据包的加解密等。这些子功能采用通用功能的处理器也可以实现,但是因为性能或成本的考量,采用硬件加速器可能更加合适。在具体的实现中,硬件加速器主要是用专用集成电路(application specified integrated circuit,ASIC)来实现。当然,硬件加速器中也可以包括一个或多个相对简单的处理器,如MCU。
基带子系统可以集成为一个或多个芯片,该芯片可称为基带处理芯片或基带芯片。基带子系统可以作为独立的芯片,该芯片可被称调制解调器(modem)或modem芯片。基带子系统可以按照modem芯片为单位来制造和销售。modem芯片有时也被称为基带处理器或移动处理器。此外,基带子系统也可以进一步集成在更大的芯片中,以更大的芯片为单位来制造和销售。这个更大的芯片可以称为系统芯片,芯片系统或片上系统(system on a chip,SoC),或简称为SoC芯片。基带子系统的软件组件可以在芯片出厂前内置在芯片的硬件组件中,也可以在芯片出厂后从其他非易失性存储器中导入到芯片的硬件组件中,或者还可以通过网络以在线方式下载和更新这些软件组件。
此外,该无线通信设备中还可包括存储器,例如图2中的内存和大容量存储器。此外, 在应用子系统和基带子系统中,还可以分别包括一个或多个缓存。具体实现中,存储器可分为易失性存储器(volatile memory)和非易失性存储器(non-volatile memory,NVM)。易失性存储器是指当电源供应中断后,内部存放的数据便会丢失的存储器。目前,易失性存储器主要是随机存取存储器(random access memory,RAM),包括静态随机存取存储器(static RAM,SRAM)和动态随机存取存储器(dynamic RAM,DRAM)。非易失性存储器是指即使电源供应中断,内部存放的数据也不会因此丢失的存储器。常见的非易失性存储器包括只读存储器(read only memory,ROM)、光盘、磁盘以及基于闪存(flash memory)技术的各种存储器等。通常来说,内存和缓存可以选用易失性存储器,大容量存储器可以选用非易失性存储器,例如闪存。
为便于描述,本申请后续实施例中,以终端为UE,接入设备为基站为例进行说明。
如图3所示,为UE通信流程示意图,包括以下步骤:
步骤301,UE完成小区选择,状态为无线资源控制(Radio Resource Control,RRC)空闲态(RRC_IDLE)。
步骤302,UE发起随机接入建立连接,状态为RRC连接态(RRC_CONNECTED),完成安全激活。
步骤303,基站查询UE能力,UE完成能力上报。
该步骤303可包括以下步骤303a至步骤303b。
步骤303a,基站对UE进行能力查询,比如基站向UE发送空口消息UECapabilityEnquiry,用于请求查询UE能力。
步骤303b,UE向基站进行能力上报,比如UE向基站发送空口消息UECapabilityInformation,用于上报UE能力。
步骤304,基站按照UE能力,为UE分配指定的资源。
为UE分配的资源包括时域资源、频域资源、配置的主小区、配置的辅小区等。
该步骤304可包括以下步骤304a至步骤304b。
步骤304a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE进行RRC重配置。
步骤304b,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
基于上述过程,可以实现为UE配置资源,从而UE可以实现通信。
UE进入RRC_CONNECTED态之后,可能发生连接挂起进入RRC非激活态(RRC_INACTIVE)。UE可以再次通过连接恢复从RRC_INACTIVE态进入RRC_CONNECTED态,连接恢复时,基站通过空口消息RRCResume分配网络资源,UE通过空口消息RRCResumeComplete通知基站完成网络资源分配。
如图4所示,为RRC状态转换流程示意图。UE可以从RRC_CONNECTED态释放连接挂起进入RRC_INACTIVE态,可以从RRC_INACTIVE态恢复连接进入RRC_CONNECTED态。可以从RRC_INACTIVE态释放连接进入RRC_IDLE态。可以从RRC_CONNECTED态释放连接进入RRC_IDLE态,可以从RRC_IDLE态恢复连接进入RRC_CONNECTED态。
下面介绍UE能力。UE能力是针对整个UE级别,用于指示UE可以支持的最高能力规格。目前,一个UE可以插入两张或两张以上的SIM卡,因此UE需要分别上报每张SIM卡对应的UE能力。为便于说明,本申请实施例中,以一个UE可以同时插入两张SIM卡为例进行说明。
UE能力包括但不限于:
1)支持进行载波聚合的最大小区数。
比如,用CA-BandwidthClassNR表示UE支持进行载波聚合的最大小区数,CA-BandwidthClassNR可以取值为1,2,3,4,5,8,等等。
2)支持的最大多输入多输出(Multiple Input and Multiple Output,MIMO)层数。
支持的最大MIMO层数,例如包括:
a,下行支持的最大MIMO层数;
比如用maxNumberMIMO-LayersPDSCH表示下行支持的最大MIMO层数,取值可以是2,4,8等。
b,码本方式上行支持的最大MIMO层数;
比如用maxNumberMIMO-LayersCB-PUSCH表示码本方式上行支持的最大MIMO层数,取值可以是1,2,4等。
c,非码本方式上行支持的最大MIMO层数;
比如用maxNumberMIMO-LayersNonCB-PUSCH表示非码本方式上行支持的最大MIMO层数,取值可以是1,2,4等。
3)补充上行(Supplementary Uplink,SUL)特性。
在近点,UE可以使用普通上行(Normal Uplink,NUL),在远点,UE可以使用SUL。SUL的频点一般低于NUL的频点,SUL的覆盖范围大于NUL的覆盖范围。当基站为UE配置了NUL和SUL之后,UE在调度时可以只用NUL,或只用SUL,或同时使用NUL和SUL。使用SUL,可以增加覆盖范围,提升上行发送速率。
SUL特性包括但不限于:
a,SUL是否可以同时发送和接收;
b,是否支持SUL动态切换;
c,是否支持SUL用于传输探测参考信号(Sounding Reference Signal,SRS)且NUL用于传输数据,或者SUL用于传输数据且NUL用于传输SRS。
从UE的角度来看,UE向基站发送信令或数据称为上行发送,UE从基站接收信令或数据称为下行接收,UE的上行能力和下行的能力可以一样,也可以不一样。
现有技术中,如果双卡UE同一时间两张SIM卡需要同时提供业务,比如:一张SIM卡用于打电话,另一张SIM卡用于上网,那么UE上报UE能力的时候,需要将UE能力进行拆分。此时,每张SIM卡上报的UE能力会比UE整体能力低,且两张SIM卡上报的UE能力之和等于UE的能力规格(也即UE的整体能力)。该使用方式下,由于每张SIM卡上报的UE能力较低,因此每张SIM卡的用户体验也就同步受损。比如,每张SIM卡上报的UE能力均为UE的规格能力的50%,则后续仅有一个SIM卡有业务执行时,该SIM卡的业务也只能至多使用该UE的能力规格的50%,从而导致该SIM卡的性能不高,降低 了用户体验。
如图5所示,为支持双卡业务并发的UE通信流程示意图,包括以下步骤:
步骤501,UE的两张SIM卡,分别完成小区选择,状态均为RRC空闲态(RRC_IDLE)。
步骤502,UE的SIM卡1发起随机接入建立连接,状态为RRC连接态(RRC_CONNECTED),完成安全激活。
步骤503,基站查询SIM卡1对应的UE能力,UE完成能力上报。
该步骤503包括以下步骤503a至步骤503b。
步骤503a,基站对UE进行能力查询,比如基站向UE发送空口消息UECapabilityEnquiry,用于请求查询SIM卡1对应的UE能力。
步骤503b,UE向基站进行能力上报,比如UE向基站发送空口消息UECapabilityInformation,用于上报SIM卡1对应的UE能力。
步骤504,基站按照SIM卡1对应的UE能力,为UE的SIM卡1分配指定的资源。
为UE的SIM卡1分配的资源包括时域资源、频域资源、配置的主小区、配置的辅小区等。
该步骤504包括以下步骤504a至步骤504b。
步骤504a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE的SIM卡1进行RRC重配置。
步骤504b,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
步骤505,UE的SIM卡2发起随机接入建立连接,状态为RRC连接态(RRC_CONNECTED),完成安全激活。
步骤506,基站查询SIM卡2对应的UE能力,UE完成能力上报。
该步骤506包括以下步骤506a至步骤506b。
步骤506a,基站对UE进行能力查询,比如基站向UE发送空口消息UECapabilityEnquiry,用于请求查询SIM卡2对应的UE能力。
步骤506b,UE向基站进行能力上报,比如UE向基站发送空口消息UECapabilityInformation,用于上报SIM卡2对应的UE能力。
步骤507,基站按照UE能力,为UE的SIM卡2分配指定的资源。
为UE的SIM卡2分配的资源包括时域资源、频域资源、配置的主小区、配置的辅小区等。
该步骤507包括以下步骤507a至步骤507b。
步骤507a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE的SIM卡2进行RRC重配置。
步骤507b,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
基于上述过程,可以实现为UE的两种SIM卡分别配置资源,从而UE可以实现通信。其中,UE上报的SIM卡1对应的UE能力与上报的SIM卡2对应的UE能力之和等于UE的能力规格。
上述方案存在的问题是:UE上报的两张SIM卡对应的UE能力之和等于UE的能力规格,导致每张SIM卡上报的UE能力都比较低。在仅有单个SIM卡的业务执行的场景下, 由于单个SIM卡对应的UE能力比较低,使得该SIM卡的业务无法获得高规格的UE能力,从而无法获得最高速率以及最低时延等体验。
为解决上述问题,本申请实施例的总体思路如下:
a)双卡UE按照标准协议规定的流程上报UE能力的时候,UE针对每个SIM卡,在上报UE能力时,均可上报UE的高规格能力。其中,SIM卡1对应的UE能力与SIM卡2对应的UE能力之和可以超过UE的能力规格。因此,在没有双卡并发业务时,SIM卡1或SIM卡2均可以支持以高规格UE能力开展业务。
b)当出现双卡并发场景时,比如SIM卡1先进行业务,当SIM卡1检测到SIM卡2将要发起业务时,UE向SIM卡1对应的网络发送能力回退消息,该能力回退消息用于触发网络重新配置或者重新调度SIM卡1对应的UE能力,从而使得UE支持并发业务。或者,SIM卡2先进行业务,当SIM卡1需要发起业务时,UE向SIM卡1对应的网络发送能力回退消息,该能力回退消息用于触发网络重新配置或者重新调度SIM卡1对应的UE能力,从而使得UE支持并发业务。
c)当双卡并发场景结束时,UE向SIM卡1对应的网络发送能力恢复消息,该能力恢复消息用于触发网络重新配置或者重新调度SIM卡1对应的UE能力,从而使得SIM卡1可以以高规格能力开展业务。
本申请实施例涉及的场景包括但不限于:
a)SIM卡1先发起业务,SIM卡2后发起业务,SIM卡1触发能力回退。
该场景等价于:SIM卡2先发起业务,SIM卡1后发起业务,SIM卡2触发能力回退。
b)SIM卡2先发起业务,SIM卡1发起业务时,SIM卡1触发能力回退。
该场景等价于:SIM卡1先发起业务,SIM卡2发起业务时,SIM卡2触发能力回退。
c)SIM卡1和SIM卡2业务并发,SIM卡2业务结束,SIM卡1触发能力恢复。
该场景等价于:SIM卡1和SIM卡2业务并发,SIM卡1业务结束,SIM卡2触发能力恢复。
d)SIM卡1和SIM卡2业务并发,SIM卡1业务结束,SIM卡1触发能力恢复。
该场景等价于:SIM卡1和SIM卡2业务并发,SIM卡2业务结束,SIM卡2触发能力恢复。
本申请实施例中资源回退或恢复的方式,包括但不限于:
1)UE向基站发送UE辅助信息UEAssistanceInformation,指示降低或者恢复指定的UE能力参数。
其中,UEAssistanceInformation内容介绍如下:
a)不携带任何参数:指示恢复所有被抑制的参数;
b)携带reducedMaxCCs:指示UE要降低到的除主小区以外的小区个数;
c)携带reducedMaxBW-FR1:指示UE低频要降低到的最大带宽;
d)携带reducedMaxBW-FR2:指示UE高频要降低到的最大带宽;
e)携带reducedMIMO-LayersFR1-DL:指示UE低频要降低到的下行MIMO层数;
f)携带reducedMIMO-LayersFR1-UL:指示UE低频要降低到的上行MIMO层数;
g)携带reducedMIMO-LayersFR2-DL:指示UE高频要降低到的下行MIMO层数;
h)携带reducedMIMO-LayersFR2-UL:指示UE高频要降低到的上行MIMO层数;
2)随机接入资源选择NUL还是SUL,如果本该在SUL接入,但UE主动在NUL接入,则网络可以评估不配置SUL。
3)UE使用一个发射端口向基站发送SRS,则指示网络仅在这一个端口下发上行授权,也即指示网络上行MIMO层数为1。或者,UE使用两个发射端口向基站发送SRS,则指示网络仅在这两个端口下发上行授权,也即指示网络上行MIMO层数为2。
4)UE向基站发送信道状态信息(channel state information,CSI)报告,CSI报告携带秩指示(Rank Indication,RI),用于指示网络下行MIMO层数与RI值相同。也即,将下行MIMO层数降低至该RI值。
5)UE主动挂起辅小区,模拟辅小区没信号的场景,由网络裁决删除辅小区。或者,UE恢复辅小区信号,则网络恢复对辅小区的使用。
6)主小区不上报辅小区的测量报告(MeasurementReport,MR),则指示网络不添加辅小区。主小区上报辅小区的测量报告,则指示网络添加辅小区。
7)主小区主动触发重建,回到一个主小区的状态。
8)卡1和卡2业务串行执行,高优先级业务先执行,低优先级业务后执行。
本申请实施例中,网络响应资源回退和恢复方式包括但不限于:
1)基站在空口向UE发送RRC重配置消息RRCReconfiguration,相关配置介绍如下:
a)针对小区个数:
配置sCellToReleaseList,用于指示删除辅小区;

b)针对SUL:

ServingCellConfig中配置supplementaryUplink,用于表示配置SUL。
c)针对下行MIMO:
PDSCH-ServingCellConfig中配置maxMIMO-Layers,用于指示网络配置的下行MIMO的层数。
d)针对上行MIMO:
PUSCH-ServingCellConfig中配置maxMIMO-Layers,或者PUSCH-Config中配置maxRank或maxRankForDCI-Format0-2-r16,用于指示网络配置的上行MIMO的层数。
2)基站在空口向UE发送RRC建立消息RRCSetup,其中携带的配置参数类似于上述RRCReconfiguration。
3)基站在空口向UE发送RRC恢复消息RRCResume,其中携带的配置参数类似于上述RRCReconfiguration。
4)基站向UE发送上行授权UL Grant,用于指示可以发送上行数据的资源。
下面结合具体示例,对本申请实施例进行说明。以下图6至图8对应的实施例中,以SIM卡1支持UE能力回退为例,对于SIM卡1和SIM卡2同时支持回退的应用举例,其实现过程类似,不再赘述。
如图6所示,为支持双卡业务并发的UE的又一种通信流程示意图。该实施例中,UE的SIM卡1先发起业务,后续SIM卡2有业务需要发起时,SIM卡1先进行UE能力回退,然后发起SIM卡2业务,待SIM卡2业务完成后,再对SIM卡1对应的UE能力进行回复。
该方法包括以下步骤:
步骤601,UE的两张SIM卡,分别完成小区选择,状态为RRC空闲态(RRC_IDLE)。
步骤602,UE的SIM卡1发起随机接入建立连接,状态为RRC连接态(RRC_CONNECTED),完成安全激活。
步骤603,基站查询SIM卡1对应的UE能力,UE完成能力上报。
该步骤603包括以下步骤603a至步骤603b。
步骤603a,基站对UE进行能力查询,比如基站向UE发送空口消息UECapabilityEnquiry,用于请求查询SIM卡1对应的UE能力。
步骤603b,UE向基站进行能力上报,比如UE向基站发送空口消息UECapabilityInformation,用于上报SIM卡1对应的UE能力。
可选的,UE上报的SIM卡1对应的UE能力可以是UE的能力规格(也即UE的整体能力)。
步骤604,基站按照SIM卡1对应的UE能力,为UE的SIM卡1分配指定的资源。
为UE的SIM卡1分配的资源包括时域资源、频域资源、配置的主小区、配置的辅小区等。
该步骤604包括以下步骤604a至步骤604b。
步骤604a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE的SIM卡1进行RRC重配置。
该步骤中,为UE的SIM卡1分配的资源是与UE上报的SIM卡1对应的UE能力相匹配的资源,比如,UE上报的SIM卡1对应的UE能力是UE整体能力,则该步骤中为UE的SIM卡1分配的资源是与UE整体能力相匹配的资源。
步骤604b,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
步骤605,SIM卡2业务准备启动,SIM卡1先完成UE能力动态回退。
该步骤605包括以下步骤605a至步骤605c。
步骤605a,UE向基站进行能力回退,比如UE向基站发送空口消息UEAssistanceInformation,用于上报SIM卡1对应的回退后的UE能力。
比如,UE在连接态,基站通过空口指示支持辅助信息上报(比如在上述步骤604a的RRCReconfiguration中配置overheatingAssistanceConfig为存在),则针对UE辅助信息(UEAssistanceInformation)中可以指示的参数,选定回退方式为UE辅助信息,网络响应为重配置。
步骤605b,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration, 用于请求对UE的SIM卡1进行RRC重配置。
该步骤中,为UE的SIM卡1分配的资源是与UE上报的SIM卡1对应的回退后的UE能力相匹配的资源。
步骤605c,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
作为示例,SIM卡1在上报UECapabilityInformation之后(比如:maxNumberMIMO-LayersCB-PUSCH为2层),网络按照UE能力进行参数配置RRCReconfiguration(比如:PUSCH-ServingCellConfig中maxMIMO-Layers为2层,PUSCH-Config中maxRank为2层),可以在两个SIM卡的业务并发前,UE发送辅助信息UEAssistanceInformation(比如:reducedMIMO-LayersFR1-UL为1层)给网络,网络重新配置(比如:PUSCH-ServingCellConfig中maxMIMO-Layers为1层,PUSCH-Config中maxRank为1层),完成SIM卡1对应的UE能力动态回退。
步骤606,UE的SIM卡2发起随机接入建立连接,状态为RRC连接态(RRC_CONNECTED),完成安全激活。
步骤607,基站查询SIM卡2对应的UE能力,UE完成能力上报。
该步骤607包括以下步骤607a至步骤607b。
步骤607a,基站对UE进行能力查询,比如基站向UE发送空口消息UECapabilityEnquiry,用于请求查询SIM卡2对应的UE能力。
步骤607b,UE向基站进行能力上报,比如UE向基站发送空口消息UECapabilityInformation,用于上报SIM卡2对应的UE能力。
步骤608,基站按照UE能力,为UE的SIM卡2分配指定的资源。
为UE的SIM卡2分配的资源包括时域资源、频域资源、配置的主小区、配置的辅小区等。

步骤605c,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
作为示例,在两个SIM卡的业务并发结束之后,如果SIM卡2业务结束,则UE发送辅助信息UEAssistanceInformation(比如:reducedMIMO-LayersFR1-UL为2层,或者不携 带任何内容)给网络,网络重新配置(比如:PUSCH-ServingCellConfig中maxMIMO-Layers为2层,PUSCH-Config中maxRank为2层),完成SIM卡1对应的UE能力动态恢复。
需要说明的是,该实施例中,UE上报的SIM卡1对应的UE能力与上报的SIM卡2对应的UE能力之和大于UE的能力规格,可选的,UE上报的SIM卡1对应的UE能力等于UE的能力规格,UE上报的SIM卡2对应的UE能力等于UE的能力规格。在单个SIM卡有业务执行的场景下,网络可以为该SIM卡的业务分配与UE的能力规格相匹配的资源,UE的单个SIM卡可以以高规格的UE能力执行业务,从而可以提升UE的性能。在双卡业务并发场景下,两个SIM卡共享UE的能力规格对应的资源,从而实现业务并发。
需要说明的是,上述流程是,上述步骤603和步骤607也可以是在UE开机时完成的,也即UE在开机之后,即完成SIM卡1对应的UE能力和SIM卡2对应的UE能力的上报。
基于上述过程,可以实现为UE的两种SIM卡分别配置资源,从而UE可以实现通信。并且,双卡UE可支持业务长时间并发,两种SIM卡上报的UE能力之和可以大于UE整体能力。在业务并发场景下,SIM卡对应的UE能力可以动态回退,从而可以保证冲突情况下的业务体验。在业务非并发场景下,SIM卡对应的UE能力可以动态恢复,UE的SIM卡可以以高规格能力运行,用户体验最佳。
如图7所示,为支持双卡业务并发的UE的又一种通信流程示意图。该实施例中,UE的SIM卡2先发起业务,后续SIM卡1有业务需要发起时,SIM卡1先进行UE能力回退,具体的,在发起随机接入连接时进行UE能力回退,然后发起SIM卡1业务。
该方法包括以下步骤:

该步骤704具体包括以下步骤704a至步骤704b。
步骤704a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE的SIM卡2进行RRC重配置。
该步骤中,为UE的SIM卡2分配的资源是与UE上报的SIM卡2对应的UE能力相匹配的资源。
步骤704b,UE向基站指示资源配置完成,比如UE向基站发送空口消息 RRCReconfigurationComplete,用于指示完成RRC重配置。

步骤707a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE的SIM卡1进行RRC重配置。
该步骤中,配置的资源中不包括SUL。
步骤707b,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
需要说明的是,该实施例中,UE上报的SIM卡1对应的UE能力与上报的SIM卡2对应的UE能力之和大于UE的能力规格,可选的,UE上报的SIM卡1对应的UE能力等于UE的能力规格,UE上报的SIM卡2对应的UE能力等于UE的能力规格。在单个SIM卡有业务执行的场景下,网络可以为该SIM卡的业务分配与UE的能力规格相匹配的资源,从而可以提升UE的整体性能。在双卡业务并发场景下,两个SIM卡共享UE的能力规格对应的资源,从而实现业务并发。
需要说明的是,上述流程是,上述步骤703和步骤706也可以是在UE开机时完成的,也即UE在开机之后,即完成SIM卡1对应的UE能力和SIM卡2对应的UE能力的上报。
基于上述过程,可以实现为UE的两种SIM卡分别配置资源,从而UE可以实现通信。并且,双卡UE可支持业务长时间并发,两种SIM卡上报的UE能力之和可以大于UE整体能力。在业务并发场景下,SIM卡对应的UE能力可以动态回退,从而可以保证冲突情况下的业务体验。在业务非并发场景下,SIM卡对应的UE能力可以动态恢复,UE的SIM卡可以以高规格能力运行,用户体验最佳。
如图8所示,为支持双卡业务并发的UE的又一种通信流程示意图。该实施例中,考虑到某些场景UE可能无法执行UE能力回退,或者无法在一定时间范围内回退成功,则UE可以选择SIM卡1和SIM卡2的业务串行执行的方式,该执行方式可以作为保底方式。
该方法包括以下步骤:
步骤801,UE的两张SIM卡,分别完成小区选择,状态为RRC空闲态(RRC_IDLE)。
步骤802,UE的SIM卡1发起随机接入建立连接,状态为RRC连接态(RRC_CONNECTED),完成安全激活。
步骤803,基站查询SIM卡1对应的UE能力,UE完成能力上报。
该步骤803包括以下步骤803a至步骤803b。
步骤803a,基站对UE进行能力查询,比如基站向UE发送空口消息UECapabilityEnquiry,用于请求查询SIM卡1对应的UE能力。
步骤803b,UE向基站进行能力上报,比如UE向基站发送空口消息UECapabilityInformation,用于上报SIM卡1对应的UE能力。
该步骤中,UE上报的SIM卡1对应的UE能力可以是UE整体能力。
步骤804,基站按照SIM卡1对应的UE能力,为UE的SIM卡1分配指定的资源。
为UE的SIM卡1分配的资源包括时域资源、频域资源、配置的主小区、配置的辅小区等。
该步骤804包括以下步骤804a至步骤804b。
步骤804a,基站对UE进行资源分配,比如基站向UE发送空口消息RRCReconfiguration,用于请求对UE的SIM卡1进行RRC重配置。
该步骤中,为UE的SIM卡1分配的资源是与UE上报的SIM卡1对应的UE能力相匹配的资源,比如,UE上报的SIM卡1对应的UE能力是UE整体能力,则该步骤中为UE的SIM卡1分配的资源是与UE整体能力相匹配的资源。
步骤804b,UE向基站指示资源配置完成,比如UE向基站发送空口消息RRCReconfigurationComplete,用于指示完成RRC重配置。
接着,SIM卡2有业务需要执行,则根据SIM卡1业务与SIM卡2业务之间的优先级,来判断执行以下步骤805a或执行步骤805b。
情形一:当SIM卡1业务优先级高于SIM卡2业务优先级,则执行以下步骤805a。
步骤805a,在SIM卡1业务结束后,SIM卡2发起业务。
具体的,SIM卡2可以执行上述步骤802至步骤804中与SIM卡1类似的操作,完成资源配置,然后SIM卡2发起业务。
情形二:当SIM卡1业务优先级低于SIM卡2业务优先级,则执行以下步骤805b。
步骤805b,SIM卡1隐式被抢占资源,SIM卡1无法真正使用空口资源;或者SIM卡1被显式抢占资源,SIM卡1进行连接释放或重建。然后,SIM卡2发起随机接入建立连接,状态为RRC_CONNECTED,完成安全激活,发起业务。SIM卡2业务结束后,SIM卡1重新发起业务。
也即,先暂停执行SIM卡1业务,待SIM卡2业务执行完成后,再继续执行SIM卡1业务。
需要说明的是,上述流程是,上述步骤803也可以是在UE开机时完成的,也即UE在开机之后,即完成SIM卡1对应的UE能力的上报。同样的,UE也可以在开机之后, 完成SIM卡2对应的UE能力的上报。
基于上述过程,可以实现为UE的两种SIM卡分别配置资源,从而UE可以实现通信。两种SIM卡上报的UE能力之和可以大于UE整体能力。每个SIM卡都可以按照最高UE规格能力串行执行不同业务,实现最大化利用UE能力。
如图9所示,为支持双卡业务并发的UE的又一种通信流程示意图。其中,UE具有第一SIM卡(或称为SIM卡1)和第二SIM卡(或称为SIM卡2),且第一SIM卡对应第一用户(或称为用户1),第二SIM卡对应第二用户(或称为用户2)。
该实施例中,第一基站与第二基站可以是同一个基站,也可以是不同的基站。作为示例,若UE的SIM卡1与SIM卡2属于不同的运营商,则SIM卡1对应的第一基站与SIM卡2对应的第二基站可能是不同的基站;若UE的SIM卡1与SIM卡2属于同一运营商,则SIM卡1对应的第一基站与SIM卡2对应的第二基站可能是相同的基站,也可能是不同的基站。
该方法包括以下步骤:
步骤901,第一基站向UE发送第一能力查询请求,相应地,UE接收第一能力查询请求。
该第一能力查询请求用于查询第一用户对应的第一UE能力。
步骤902,UE向第一基站发送第一能力上报消息,相应地,基站接收第一能力上报消息。
该第一能力上报消息携带第一UE能力的指示信息。也即,第一能力上报消息携带指示信息,该指示信息用于指示第一UE能力,第一UE能力即为第一用户对应的UE能力。
步骤903,第二基站向UE发送第二能力查询请求,相应地,UE接收第二能力查询请求。
该第二能力查询请求用于查询第二用户对应的第二UE能力。
步骤904,UE向第二基站发送第二能力上报消息,相应地,基站接收第二能力上报消息。
该第二能力上报消息携带第二UE能力的指示信息。也即,第二能力上报消息携带指示信息,该指示信息用于指示第二UE能力,第二UE能力即为第二用户对应的UE能力。
其中,第一UE能力、第二UE能力均不大于UE的能力规格,UE的能力规格由第一用户和第二用户共享,且第一UE能力与第二UE能力之和大于UE的能力规格。
基于上述方案,单个用户上报的UE能力可以比现有技术更高,并且,上报的第一用户对应的UE能力与上报的第二用户对应的UE能力之和大于UE的能力规格。因此,在单个用户有业务执行的场景下,基站可以基于上报的该用户对应更高的UE能力,为该用户的业务分配相应的资源。相较于现有技术,可以提升单个用户有业务执行场景下的UE性能。由于业务并发的场景并不总是存在,因此,采用上述方案有利于提升多SIM卡的UE的整体性能。
作为一种可能的实现方法,UE的能力规格包括以下一项或多项:
1)UE支持进行载波聚合的最大小区数;
2)UE支持的最大多输入多输出MIMO层数;
3)UE的补充上行特性。
关于UE的能力规格的具体描述,参考前述描述,不再赘述。
由于UE的能力规格由第一用户和第二用户共享,因此当UE上只有单个用户有业务执行时,网络侧可以基于该用户对应的UE能力,为该用户分配相应的资源。比如,第一用户在上网或打电话等,第二用户没有业务,则第一基站可以基于UE上报的第一用户对应的第一UE能力,为第一用户分配相应资源,为第一用户分配的资源不超过UE的能力规格对应的最大资源量。再比如,第二用户在上网或打电话等,第一用户没有业务,则第二基站可以基于UE上报的第二用户对应的第二UE能力,为第二用户分配相应资源,为第二用户分配的资源不超过UE的能力规格对应的最大资源量。当UE上的两个用户同时有业务执行(比如,第一用户上网,第二用户对外寻呼或者被寻呼)时,第一基站可以基于第一用户对应的第一UE能力为第一用户分配相应的资源,第二基站可以基于第二用户对应的第二UE能力为第二用户分配相应的资源,并且,为第一用户分配的资源与为第二用户分配的资源的总和不超过UE的能力规格对应的最大资源量。也即,第一用户和第二用户均只能使用UE的部分能力。
由于第一UE能力与第二UE能力之和大于UE的能力规格,因此,在第一用户与第二用户有业务并发执行时,为保障为第一用户使用的UE能力与第二用户使用的UE能力之和不超过UE的能力规格,在业务并发之前,可以适当降低为第一用户实际配置的UE能力和/或降低为第二用户实际配置的UE能力。
需要说明的是,UE上报的第一用户对应的第一UE能力指的是第一用户对应的UE能力的上限,UE上报的第二用户对应的第二UE能力指的是第二用户对应的UE能力的上限,后续在第一用户与第二用户有业务并发时,当需要对第一用户对应的UE能力进行回退时,UE可以以某种方式向第一基站告知回退后的UE能力,也即第一用户实际使用的UE能力。或者是,当需要对第二用户对应的UE能力进行回退时,UE可以以某种方式向第二基站告知回退后的UE能力,也即第二用户实际使用的UE能力。需要说明的是,第一用户对应的第一用户对应的第一UE能力不会发生变化,第一用户实际使用的UE能力是可以根据业务需要进行回退或恢复的,也即第一用户实际使用的UE能力是可以发生变化的。同样,第二用户对应的第二UE能力不会发生变化,第二用户实际使用的UE能力是可以根据业务需要进行回退或恢复的,也即第二用户实际使用的UE能力是可以发生变化的。
当此后,当两个用户有业务需要并发执行,本申请实施例可以将其中一个用户对应的终端能力主动进行回退,以减少该用户需占用的终端能力,从而可以为另一用户预留一部分的终端能力,进而实现业务并发。比如,在确定第一用户正在执行第一业务、且第二用户需要发起第二业务;或者,确定第一用户需要发起第一业务、且第二用户正在执行第二业务的情况下,本申请实施例提供以下不同的能力回退方法,包括但不限于:
方法1,UE向第一基站发送能力回退消息,能力回退消息用于降低第一用户使用的UE能力。
比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送能力回退消息,降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在 第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过发送能力回退消息,降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,实现第一业务与第二业务的并发执行。
可选的,能力回退消息携带第一辅助信息,第一辅助信息携带以下信息中的一项或多项:
用于指示UE要降低到的除主小区以外的小区个数的指示信息;
用于指示UE低频要降低到的最大带宽的指示信息;
用于指示UE高频要降低到的最大带宽的指示信息;
用于指示UE低频要降低到的下行MIMO层数的指示信息;
用于指示UE低频要降低到的上行MIMO层数的指示信息;
用于指示UE高频要降低到的下行MIMO层数的指示信息;
用于指示UE高频要降低到的上行MIMO层数的指示信息;
用于指示UE不支持补充上行的指示信息。
可选的,第一辅助信息为UEAssistanceInformation。
作为示例,UE的能力规格包括:UE低频支持的上行最大MIMO层数为4,UE向第一基站上报的第一用户对应的第一UE能力包括:UE低频支持的上行最大MIMO层数为4,UE通过向第一基站发送第一辅助信息,该第一辅助信息携带用于指示UE低频要降低到的下行MIMO层数为2的指示信息,从而告知第一基站:第一用户低频实际使用的MIMO层数最大为2。
方法2,使用N个发射端口向第一基站发送探测参考信号,其中,N小于第一用户对应的上行MIMO层数。
这里的发射端口,指的是用于发送探测参考信号的天线端口。
基于上述方案,使用N个发射端口向第一接入设备发送探测参考信号,则指示第一接入设备上行MIMO层数为N,且N小于第一用户对应的上行MIMO层数,也即指示第一接入设备将上行MIMO层数减少到N个。如此,可以降低第一用户使用的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,实现第一业务与第二业务的并发执行。
作为示例,UE上报的第一用户对应的第一用户能力包括:UE低频支持的最大上行MIMO层数为4,则第一基站配置第一用户使用4个天线端口来发送SRS。后续当第一用户想要降低实际使用的UE能力时,UE可以在少于4个天线端口(以3个为例)上向第一基站发送SRS,当第一基站在3个天线端口上接收到SRS,则第一基站将第一用户对应的低频上行MIMO层数降低为3或3以下,从而实现降低第一用户实际使用的UE能力。
方法3,向第一基站发送信道状态信息,信道状态信息携带秩指示,秩指示用于指示 下行MIMO层数与秩指示对应的值相同,其中,下行MIMO层数小于或等于第一用户对应的下行MIMO层数。
基于上述方案,通过发送携带秩指示的信道状态信息,从而指示下行MIMO层数与秩指示对应的值相同,也即指示接入设备将下行MIMO层数减少到秩指示对应的值。如此,可以降低第一用户使用的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,实现第一业务与第二业务的并发执行。
作为示例,UE上报的第一用户对应的第一用户能力包括:UE低频支持的最大下行MIMO层数为4。后续当第一用户想要降低实际使用的UE能力时,UE可以向第一基站发送信道状态信息,其中携带秩指示,该秩指示对应的值小于4(以3为例)。当第一基站接收到信道状态信息,则第一基站将第一用户对应的低频下行MIMO层数降低为3或3以下,从而实现降低第一用户实际使用的UE能力。
方法4,使用第一用户对应的主小区,但不使用第一用户对应的辅小区。
基于上述方案,使用所述第一用户对应的主小区,但不使用所述第一用户对应的辅小区,模拟辅小区没信号的场景,从而触发第一接入设备裁决删除辅小区。如此,可以降低第一用户使用的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,实现第一业务与第二业务的并发执行。
方法5,向第一基站发送测量报告,测量报告不包括第一用户对应的辅小区的测量报告。
基于上述方案,终端不向第一接入设备上报第一用户对应的辅小区的测量报告,从而指示第一接入设备不添加辅小区。如此,可以降低第一用户当前支持的终端能力。比如,在第一用户正在执行第一业务、且第二用户需要发起第二业务的场景下,通过发送降低第一用户使用的终端能力,可以为第二用户预留一部分终端能力,从而第二终端设备可以执行第二业务,实现第一业务与第二业务的并发执行。再比如,在第一用户需要发起第一业务、且第二用户正在执行第二业务的场景下,通过降低第一用户使用的终端能力,使得第一用户使用的终端能力与第二用户使用的终端能力之和不超过终端的能力规格,从而第一用户可以执行第一业务,实现第一业务与第二业务的并发执行。
后续,当第一业务或第二业务结束后,可以恢复第一用户使用的UE能力。作为一种 可能的实现方法,向第一基站发送能力恢复消息,能力恢复消息用于提高第一用户使用的UE能力。
可选的,能力恢复消息携带第二辅助信息,第二辅助信息携带以下信息中的一项或多项:
用于指示UE要提高到的除主小区以外的小区个数的指示信息;
用于指示UE低频要提高到的最大带宽的指示信息;
用于指示UE高频要提高到的最大带宽的指示信息;
用于指示UE低频要提高到的下行MIMO层数的指示信息;
用于指示UE低频要提高到的上行MIMO层数的指示信息;
用于指示UE高频要提高到的下行MIMO层数的指示信息;
用于指示UE高频要提高到的上行MIMO层数的指示信息;
用于指示UE支持补充上行的指示信息。
可选的,第二辅助信息为UEAssistanceInformation。
可选的,能力恢复消息不携带任何参数,则该能力恢复消息用于指示恢复所有抑制的参数,也即恢复到UE能力降低之前的参数。
