Description

一种部分带宽切换方法及相关装置 技术领域
本申请涉及通信技术领域,尤其涉及一种部分带宽切换方法及相关装置。
背景技术
目前,网络设备可为终端设备(user equipment,UE)所在的一个小区配置多个部分带宽(bandwidth part,BWP)。为了提高吞吐率或者降低时延,或者提高BWP的利用率,通信系统可支持多个BWP处于激活状态,即存在多个活跃的BWP(active BWP)。
然而,当存在多个活跃的BWP时,会带来终端设备耗电较大的问题。那么,在该情况下,如何在保持通信性能的同时兼顾终端设备的功耗,为目前亟需研究的问题之一。
发明内容
本申请实施例提供了一种部分带宽切换方法及相关装置,可在保持通信性能的同时兼顾终端设备的功耗。
第一方面,本申请实施例提供了一种部分带宽切换方法,该方法包括:终端设备在一个小区内的活跃的部分带宽BWP上满足定时器启动/重启动条件时,启动/重启动与所述活跃的BWP相关联的定时器;若该定时器超时,则终端设备从所述活跃的BWP切换到默认下行BWP或初始下行BWP。
可见,当一个小区内的活跃的BWP处于激活状态时,终端设备将该活跃的BWP与一个定时器关联,并通过该定时器控制活跃的BWP的切换,从而避免终端设备在定时器超时后,继续在无效的BWP(活跃的BWP)上监控和/或传输,即该方法在保持通信性能的同时兼顾了终端设备的功耗。

这是由于终端设备被配置有下行链路部分带宽标识时,活跃的BWP不是该默认下行链路部分带宽标识指示的默认下行BWP,因此若与活跃的BWP相关联的定时器超时,则终端 设备可从该活跃的BWP切换到默认下行链路部分带宽标识指示的默认下行BWP,以实现对活跃的BWP的切换。
另一种可选的实施方式中,若上述定时器超时,则终端设备从活跃的BWP切换到默认下行BWP或初始下行BWP上,包括:若终端设备未被配置有默认下行链路部分带宽标识,且定时器超时,则终端设备从活跃的BWP切换到初始下行BWP上。
这是由于当终端设备未被配置有默认下行链路部分带宽标识时,活跃的BWP不是初始下行BWP,因此若与活跃的BWP相关联的定时器超时,则终端设备可从该活跃的BWP切换到初始下行BWP,以实现对活跃的BWP的切换。

又一种可选的实施方式中,上述定时器启动/重启动的条件为:终端设备在配置的下行链路分配中接收到介质访问控制层MAC的协议数据单元PDU,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。

本申请实施例中的终端设备,也可以称为终端,可以指各种形式的用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台(mobile station,MS)、 远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,第五代移动通信(5th generation mobile communication,5G)网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network,PLMN)中的终端设备等,本申请实施例对此并不限定。
本申请实施例中,网络设备是连接到网络中的物理实体,网络设备包括接入网的基站和基站控制器。
本申请实施例中的基站(base station,BS),也可称为基站设备,是一种部署在无线接入网(wireless access network,RAN)中用以提供无线通信功能的装置。例如,在第二代移动通信(2th generation mobile communication,2G)网络中提供基站功能的设备包括基地无线收发站(base transceiver station,BTS)。第三代移动通信(3th generation mobile communication,3G)网络中提供基站功能的设备包括节点B(NodeB)。在第四代移动通信(4th generation mobile communication,4G)网络中提供基站功能的设备包括演进的节点B(evolved NodeB,eNB)。在无线局域网络(Wireless Local Area Networks,WLAN)中,提供基站功能的设备为接入点(Access Point,AP)。5G新无线(New Radio,NR)中的提供基站功能的设备gNB,以及继续演进的节点B(ng-eNB),其中gNB和终端设备之间采用NR技术进行通信,ng-eNB和终端之间采用演进的通用地面无线接入(evolved universal terrestrial radio access,E-UTRA)技术进行通信,gNB和ng-eNB均可连接到5G核心网。本申请实施例中的基站还包含在未来新的通信系统中提供基站功能的设备等。

本申请也适用于不同的网络架构,包括但不限于中继网络架构、双链接架构、车辆到 任何物体的通信(vehicle-to-everything,V2X)架构、设备到设备的通信(Device-to-Device,D2D)等架构。
目前,在NR通信系统的R15/R16/R17协议中,对于下行部分带宽(bandwidth part,BWP),如果网络设备给终端设备配置了默认下行链路部分带宽标识(defaultDownlink BWP-Id),则活跃的BWP(处于激活状态的BWP)不是default downlink BWP-Id所指示的BWP,且如果网络设备给终端设备配置了休眠部分带宽标识(dormantBWP-Id),则活跃的BWP不是dormantBWP-Id所指示的BWP。如果网络设备未给终端设备配置defaultDownlink BWP-Id,则活跃的BWP不是初始下行BWP,且如果网络设备给终端设备配置了休眠部分带宽标识(dormantBWP-Id),则活跃的BWP不是dormantBWP-Id所指示的BWP。
另外,在R15/R16/R17协议中,网络设备可为终端设备所在的一个小区配置多个BWP。但在任一时刻,只有一个BWP被激活。对于基于定时器(timer)的BWP切换机制,若被激活的BWP关联的定时器超时,则终端设备会从该活跃的BWP切换至其他BWP上,以使得终端设备在其他BWP上保持通信的连续性,且有效降低终端设备的功耗。
其中,终端设备启动/重启动与活跃的BWP相关联的定时器的条件有以下四种实施方式:
1.终端设备在活跃的BWP上接收到用于指示下行分配(downlink assignment)或上行授权(uplink grant)的物理下行控制信道(physical downlink control channel,PDCCH),且,
终端设备基于接收的小区无线网络临时标识(cell-radio network temporary identifier,C-RNTI)加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程;
其中,用于指示下行分配或上行授权的PDCCH是通过小区无线网络临时标识C-RNTI或配置调度的无线网络临时标识(configured scheduling-radio network temporary identifier,CS-RNTI)加扰的。
也就是说,终端设备启动/重启动与活跃的BWP相关联的定时器的一个条件为:A PDCCH addressed to C-RNTI or CS-RNTI indicating downlink assignment or uplink grant is received on the active BWP,the ongoing Random Access procedure associated with this Serving Cell is successfully completed upon reception of this PDCCH addressed to C-RNTI,or there is no ongoing Random Access procedure associated with this Serving Cell。
2.终端设备接收到用于活跃的BWP的指示下行分配或上行授权的物理下行控制信道PDCCH,且,
终端设备基于接收的小区无线网络临时标识C-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程;
其中,用于指示下行分配或上行授权的PDCCH是通过小区无线网络临时标识C-RNTI或配置调度的无线网络临时标识CS-RNTI加扰的。
也就是说,终端设备启动/重启动与活跃的BWP相关联的定时器的一个条件为:A PDCCH addressed to C-RNTI or CS-RNTI indicating downlink assignment or uplink grant is received for the active BWP,the ongoing Random Access procedure associated with this Serving Cell is successfully completed upon reception of this PDCCH addressed to C-RNTI,or there is no ongoing Random Access procedure associated with this Serving Cell。
3.终端设备在介质访问控制层(medium access control,MAC)的协议数据单元PDU在配置的上行链路中可传输,没有接收到来自比MAC层更低层的先听后说(listen before talk,LBT)侦听失败的指示,且,
终端设备基于接收的小区无线网络临时标识C-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。
也就是说,终端设备启动/重启动与活跃的BWP相关联的定时器的一个条件为:A MAC PDU is transmitted in a configured uplink grant and LBT failure indication is not received from lower layers,the ongoing Random Access procedure associated with this Serving Cell is successfully completed upon reception of this PDCCH addressed to C-RNTI,or there is no ongoing Random Access procedure associated with this Serving Cell。
4.终端设备在配置的下行链路分配(configured downlink assignment)中接收到介质访问控制层MAC的协议数据单元PDU,且,
终端设备基于接收的小区无线网络临时标识C-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。
也就是说,终端设备启动/重启动与活跃的BWP相关联的定时器的一个条件为:if a MAC PDU is received in a configured downlink assignment,the ongoing Random Access procedure associated with this Serving Cell is successfully completed upon reception of this PDCCH addressed to C-RNTI,or there is no ongoing Random Access procedure associated with this Serving Cell。
那么,终端设备在活跃的BWP上满足上述四种条件中的任一条件时,终端设备启动/重启动与该活跃的BWP相关联的定时器(即bwp-InactivityTimer)。另外,若该定时器超时,且终端设备被配置了defaultDownlinkBWP-Id,则终端设备从这个活跃的BWP切换到该defaultDownlinkBWP-Id所指示的默认下行BWP上;若该定时器超时,且终端设备未被配置defaultDownlinkBWP-Id,则终端设备从这个活跃的BWP切换到初始下行BWP。从而终端设备实现了对该活跃BWP的切换。进而终端设备可在定时器超时后,在默认下行BWP或初始下行BWP进行数据的传输,可保持通信的连续性。
然而,在未来通信系统(比如7G系统)中,为提高BWP的利用率或者吞吐量或者降低时延,会在任一时刻,支持一个小区内多个BWP处于激活状态,即网络设备给终端设备配置的一个小区内的多个BWP可处于部分或者全部激活状态,那么将存在多个活跃的BWP。
然而,当存在多个活跃的BWP时,会带来终端耗电问题。那么,在该情况下,如何在保持通信性能的同时兼顾终端设备的功耗,为目前亟需研究的问题之一。
本申请实施例提供一种部分带宽切换方法。该方法中,终端设备在一个小区内的多个活跃的部分带宽BWP中的任一BWP上满足定时器启动/重启动条件时,启动/重启动与该多个活跃的BWP相关联的定时器;若该定时器超时,则终端设备从多个活跃的BWP切换到默认下行BWP或初始下行BWP。可见,终端设备可通过一个定时器控制多个活跃的BWP的切换,从而实现多个活跃的BWP的切换,进而可兼顾通信性能和终端设备的功耗,另外也可使得终端设备在多个活跃的BWP失效时保持通信的连续性。
需说明的是,本申请实施例中的组无线网络临时标识(group-radio network temporary identifier,G-RNTI)是用于广播和/或组播调度的RNTI,本申请实施例不限定其具体的命名。
需说明的是,本申请实施例中的配置调度的组无线网络临时标识(configured scheduling-group-radio network temporary identifier,G-CS-RNTI)是用于广播和/或组播的配 置调度的RNTI,本申请实施例不限定其具体的命名。
基于上述描述,本申请实施例提出一种如图2所示的部分带宽切换方法,该方法可以包括S201-S202:
S201:终端设备在一个小区内的多个活跃的部分带宽BWP中的任一活跃BWP上满足定时器启动/重启动条件时,启动/重启动与该多个活跃的BWP相关联的定时器。
可理解的,当一个小区存在多个活跃的BWP(即一个小区中,多个BWP处于激活状态)时,终端设备将该多个活跃的BWP与一个定时器关联,该定时器用于控制该多个活跃的BWP的切换。
另外,终端设备在多个活跃的BWP中的任一活跃的BWP满足该定时器的启动/重启动条件时,就启动/重启动该定时器,以通过定时器监控该多个活跃的BWP是否可用。
其中,上述定时器启动/重启动的条件具有以下几种实施方式:
实施方式1:终端设备在多个活跃的BWP中的任一活跃的BWP上接收到用于指示下行分配或上行授权的物理下行控制信道PDCCH,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程;
其中,用于指示下行分配或上行授权的PDCCH是通过以下一种加扰的:小区无线网络临时标识C-RNTI、配置调度的无线网络临时标识CS-RNTI、组无线网络临时标识G-RNTI、配置调度的组无线网络临时标识G-CS-RNTI。
实施方式2:终端设备接收到用于多个活跃的BWP中的任一活跃的BWP的指示下行分配或上行授权的物理下行控制信道PDCCH,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程;
其中,用于指示下行分配或上行授权的PDCCH是通过以下一种加扰的:小区无线网络临时标识C-RNTI、配置调度的无线网络临时标识CS-RNTI、组无线网络临时标识G-RNTI、配置调度的组无线网络临时标识G-CS-RNTI。
实施方式3:终端设备在介质访问控制层MAC的协议数据单元PDU在配置的上行链路中可传输,没有接收到来自比MAC层更低层的先听后说LBT侦听失败的指示,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。
实施方式4:终端设备在配置的下行链路分配中接收到介质访问控制层MAC的协议数据单元PDU,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。
也就是说,当一个小区内的多个BWP处于激活状态时,多个活跃的BWP中的任一活跃的BWP满足上述实施方式1至实施方式4中的其中一种方式下的条件时,就启动/重启动与该多个活跃的BWP相关联的定时器,以开启对多个活跃的BWP的监控。
S202:若定时器超时,则终端设备从多个活跃的BWP切换到默认下行BWP或初始下行BWP上。
可理解的,若与上述多个活跃的BWP相关联的定时器超时,则可能意味着该多个BWP上的带宽被使用完,或者已没有数据在该多个活跃的BWP上需要传输,即该多个活跃的BWP失效,终端设备不会或无法在该多个活跃的BWP上传输数据。因此终端设备从该多个活跃的BWP切换到默认下行BWP或初始下行BWP,以使得终端设备在默认下行BWP或初始下行BWP上继续进行数据的传输,可避免终端设备在定时器超时后,继续在多个无效的BWP(多个活跃的BWP)上监控和/或传输,可兼顾通信性能和终端设备的功耗,即该方法可在提高通信性能的同时有效降低终端设备的功耗。
一种可选的实施方式中,若上述定时器超时,则终端设备从多个活跃的BWP切换到默认下行BWP或初始下行BWP上,包括:若终端设备被配置有默认下行链路部分带宽标识,且定时器超时,则终端设备从多个活跃的BWP切换到默认下行链路部分带宽标识指示的默认下行BWP。
这是由于网络设备给终端设备配置下行链路部分带宽标识时,活跃的BWP不是该默认下行链路部分带宽标识指示的默认下行BWP,因此若与多个活跃的BWP相关联的定时器超 时,则终端设备可从该多个活跃的BWP切换到默认下行链路部分带宽标识指示的默认下行BWP,实现对多个活跃的BWP的切换,使得终端设备继续在默认下行BWP上继续进行数据传输,以降低终端设备的功耗。
另一种可选的实施方式中,若上述定时器超时,则终端设备从多个活跃的BWP切换到默认下行BWP或初始下行BWP上,包括:若终端设备未被配置有默认下行链路部分带宽标识,且定时器超时,则终端设备从多个活跃的BWP切换到初始下行BWP上。
这是由于网络设备给终端设备未配置默认下行链路部分带宽标识,活跃的BWP不是初始下行BWP,因此若与多个活跃的BWP相关联的定时器超时,则终端设备可从该多个活跃的BWP切换到初始下行BWP,以实现对多个活跃的BWP的切换,同时使得终端设备在初始下行BWP上继续进行数据的传输,可保持通信的持续性和降低终端设备的功耗。
本申请实施例中,当一个小区内的多个BWP处于激活状态时,终端设备将该多个活跃的BWP与一个定时器关联;若该定时器超时,则终端设备从多个活跃的BWP切换到默认下行BWP或初始下行BWP。也就是说,终端设备通过一个定时器实现对多个活跃的BWP的切换,从而避免终端设备在定时器超时后,在无效的BWP无法进行通信的问题,即该方法可使得终端设备保持通信的连续性,同时也可降低终端设备的功耗。
本申请实施例还提供一种部分带宽切换方法200。该方法中,终端设备将所在的一个小区内的多个活跃的部分带宽BWP分别关联一个定时器。对于每一个活跃的BWP,若其关联的定时器超时,且不存在其他活跃的BWP,则终端设备将该活跃的BWP去激活,且从该活跃的BWP切换到默认下行BWP或初始下行BWP;若其关联的定时器超时,且存在其他活跃的BWP,则终端设备将该活跃的BWP去激活。可见,终端设备可将一个活跃BWP关联一个定时器,从而实现一个或者多个活跃的BWP的切换,进而可使得终端设备保持通信的连续性,且兼顾终端设备的功耗。
其中,所述每个活跃BWP关联的定时器,其计时到期的计时时长相同,或者不同,本申请实施例不做限定。
基于上述描述,本申请实施例提出一种如图3所示的部分带宽切换方法,该方法可以包括S301-S302:
S301:终端设备在一个小区内的多个活跃的部分带宽BWP中的某一活跃BWP上满足定时器启动/重启动条件时,启动/重启动与该活跃的BWP相关联的定时器。
可理解的,当一个小区中存在多个活跃的BWP(即一个小区中,多个BWP处于激活状态)时,终端设备将该多个活跃的BWP分别与一个定时器关联,即一个活跃的BWP关联一个定时器,每个定时器用于控制与该定时器关联的活跃BWP的切换或者去激活。
另外,终端设备在多个活跃的BWP中的某一活跃的BWP满足该定时器的启动/重启动条件时,就启动/重启动该定时器,以通过定时器监控该活跃的BWP是否可用。
其中,上述定时器启动/重启动的条件具有以下几种实施方式:
实施方式1:终端设备在活跃的BWP上接收到用于指示下行分配或上行授权的物理下行控制信道PDCCH,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程;
其中,用于指示下行分配或上行授权的PDCCH是通过以下一种加扰的:小区无线网络临时标识C-RNTI、配置调度的无线网络临时标识CS-RNTI、组无线网络临时标识G-RNTI、配置调度的组无线网络临时标识G-CS-RNTI。
实施方式2:终端设备接收到用于活跃的BWP的指示下行分配或上行授权的物理下行控制信道PDCCH,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程;
其中,用于指示下行分配或上行授权的PDCCH是通过以下一种加扰的:小区无线网络临时标识C-RNTI、配置调度的无线网络临时标识CS-RNTI、组无线网络临时标识G-RNTI、配置调度的组无线网络临时标识G-CS-RNTI。
实施方式3:终端设备在介质访问控制层MAC的协议数据单元PDU在配置的上行链路中可传输,没有接收到来自比MAC层更低层的先听后说LBT侦听失败的指示,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。
实施方式4:终端设备在配置的下行链路分配中接收到介质访问控制层MAC的协议数 据单元PDU,且,
终端设备基于接收的小区无线网络临时标识C-RNTI或者组无线网络临时标识G-RNTI加扰的物理下行控制信道PDCCH,关联于当前服务小区的正在进行的随机访问过程成功完成,或者没有关联于当前服务小区的正在进行的随机访问过程。
也就是说,当多个BWP处于激活状态时,多个活跃的BWP中的任一活跃的BWP满足上述实施方式1至实施方式4中的其中一种方式下的条件时,就启动/重启动与满足定时器启动/重启动的条件的活跃的BWP相关联的定时器,以开启对该活跃的BWP的监控。
S302:若定时器超时,且不存在其他活跃的BWP,则终端设备从该活跃的BWP切换到默认下行BWP或初始下行BWP上;若定时器超时,且存在其他活跃的BWP,则终端设备将该活跃的BWP去激活。
可理解的,若与上述多个活跃的BWP中的任一BWP相关联的定时器超时,则可能意味着该任一BWP上的带宽被使用完,或者已没有数据在该任一活跃的BWP上需要传输,即该活跃的BWP失效,终端设备不会或无法在该活跃的BWP上传输数据。因此,该活跃BWP去激活,可有效降低终端功耗。如果也不存在其他激活BWP,则终端设备切换到默认下行BWP或初始下行BWP,以使得终端设备在默认下行BWP或初始下行BWP上继续进行数据的传输,即使得终端设备保持通信的连续性;终端切换到默认下行BWP或初始下行BWP进行监控和/或传输,也可以有效降低终端功耗。
可理解的,上述终端设备将活跃的BWP去激活指的是使该活跃的BWP处于未激活状态,也即终端设备不再使用该BWP。
一种可选的实施方式中,若上述定时器超时,且不存在其他激活BWP,则终端设备从该活跃的BWP切换到默认下行BWP或初始下行BWP上,包括:若终端设备被配置有默认下行链路部分带宽标识,且定时器超时,且不存在其他激活BWP,则终端设备从该活跃的BWP切换到默认下行链路部分带宽标识指示的默认下行BWP。
这是由于网络设备给终端设备配置下行链路部分带宽标识时,活跃的BWP不是该默认下行链路部分带宽标识指示的默认下行BWP,因此若定时器超时,且不存在其他激活BWP,则终端设备可切换到默认下行链路部分带宽标识指示的默认下行BWP,实现对一个或者多个活跃的BWP的切换,使得终端设备继续在默认下行BWP上继续进行数据传输,降低终端设备的功耗。
另一种可选的实施方式中,若上述定时器超时,且不存在其他激活BWP,则终端设备从该活跃的BWP切换到默认下行BWP或初始下行BWP上,包括:若终端设备未被配置有默认下行链路部分带宽标识,且定时器超时,且不存在其他激活BWP,则终端设备从该活跃的BWP切换到初始下行BWP上。
这是由于网络设备给终端设备未配置默认下行链路部分带宽标识,活跃的BWP不是初始下行BWP,因此若定时器超时,且不存在其他激活BWP,则终端设备可从该一个或者多个活跃的BWP切换到初始下行BWP,以实现对多个活跃的BWP的切换,同时使得终端设备在下行BWP上继续进行数据的传输,保持通信的持续性和降低终端设备的功耗。
本申请实施例中,当一个小区中的多个BWP处于激活状态时,终端设备将该多个活跃的BWP分别与一个定时器关联,也即每个活跃的BWP关联一个定时器;对于每一个活跃的BWP,若其关联的定时器超时,且不存在其他活跃的BWP,则终端设备将这个活跃的BWP去激活,且切换到默认下行BWP或初始下行BWP;若其关联的定时器超时,且存在其他活跃的BWP,则终端设备将这个活跃的BWP去激活。可见,终端设备可通过一个活跃BWP关联一个定时器的方式,实现一个或者多个活跃的BWP的去激活和/或者切换,进而可使得终端设备保持通信的连续性,且在保持通信性能的同时兼顾终端设备的功耗。
