随着移动通信技术的发展,引入了越来越多的提高通信效率的技术。例如:
(1)关于带宽部分(Bandwidth Part,BWP)简介:
在第五代移动通信技术(Fifth-generation,5G)系统中,UE可能只能支持一个比较小的工作带宽(例如:5MHz),而网络侧的一个小区会支持比较大的带宽(例如:100MHz),该大带宽中的UE工作的小带宽部分则认为是BWP。从UE配置的角度,对于不同的UE功能,BWP可以作为是一个小区下的BWP。
网络侧可配置UE有一个或多个BWP,并可通过BWP变换(switching)命令(例如:物理下行控制信道(Physical Downlink Control Channel,PDCCH)指示信息)变换UE当前激活的BWP,即激活新的BWP并去激活当前激活的BWP。
另外,网络侧可以对于一个激活的BWP配置BWP非激活定时器(BWP-Inactivity Timer),UE在激活一个BWP后启动该BWP非激活定时器,然后在该BWP非激活定时器超时后将激活的BWP变换到网侧络配置默认的BWP(default BWP)。
(2)关于随机接入过程简介:
随机接入过程主要分为:非竞争随机接入和竞争随机接入。
非竞争随机接入的过程如图1所示,主要分为三步:
步骤101、基站向UE发送Msg0消息。
具体地,基站向UE分配用于非竞争随机接入的专用随机接入资源。
步骤102、UE向基站发送Msg1消息。
具体地,UE根据Msg0消息指示的随机接入资源,在指定的随机接入资源上向基站发送指定的专用随机接入信号。
UE在发送Msg1消息后,根据Msg1消息的发送时间和频率的位置计算网络侧调度Msg2消息的标识信息(例如:随机接入无线网络临时标识(Random Access Radio Network Temporary Identity,RA-RNTI))。计算方式如下:
RA-RNTI=1+t_id+10×f_id
其中:t_id是随机接入信号的子帧标识,f_id是随机接入信号的频域标识。
UE在发送Msg1后,在一个固定窗口内(例如:随机接入响应窗口(Random Access Response window,RAR window))监听下行信道以获取网络侧的反馈信息Msg2消息。该RAR window的开始位置为Msg1消息发送结束的子帧加上3个子帧,RAR window的长度为网侧络配置的长度。
步骤103、基站向UE发送Msg2消息。
具体地,基站向UE发送随机接入响应(Random Access Response,RAR),随机接入响应中包含:Msg1标识信息(例如:随机接入前导码标识(Random Access Preamble Identifier,RAPID));定时提前量(Timing Advance)信息;上行发送授权信息(ULGrant);回退信息(Backoff Indicator);临时用户设备标识信息(Temporary C-RNTI)。如果UE接收随机接入响应失败,则根据RAR中指示的回退信息,确定下次发送随机接入的时刻。UE在Msg2消息中收到其发送的Msg1消息标识信息,UE认为随机接入过程结束。
竞争随机接入的过程如图2所示,主要分为四步:
步骤201、UE向基站发送Msg1消息。
具体地,UE选择随机接入资源并利用该随机接入资源向基站发送所选的随机接入信号。其中RA-RNTI和RAR window的计算方式同非竞争随机接入过程。
步骤202、基站向UE发送Msg2消息。
具体地,基站接收到Msg1消息,计算定时提前量(Timing Advance,TA),并向UE发送随机接入响应消息,随机接入响应消息中至少包含该定时提前量信息和针对Msg3消息的UL grant。UE通过RA-RNTI的PDCCH接收Msg2消息。
步骤203、UE向基站发送Msg3消息。
具体地,UE在Msg2消息指定的UL grant上发送上行传输,不同随机接入原因Msg3消息上行传输的内容不同,例如:对于初始接入,Msg3消息传输的是无线资源控制(Radio Resource Control,RRC)连接建立请求。
步骤204、基站向UE发送Msg4消息。
上述Msg4消息为竞争解决消息,UE根据Msg4消息可以判断随机接入是否成功。
(3)关于多波束(beam)简介:
未来5G系统中,为达到下行链路传输速率20Gbps,上行链路传输速率10Gbps的目标,高频通信和大规模天线技术将会被引入。高频通信可提供更宽的系统带宽,天线尺寸也可以更小,更加有利于大规模天线在基站和UE中部署。基站侧多波束/多收发节点(Multi-beam/Multi-TRP)发送和接收,UE侧Multi-beam的发送和接收将会广泛应用。以新无线(New Radio,NR)物理上行共享信道(New Radio Physical Uplink Sharing Channel,PUSCH)为例,上行链路Multi-beam传输示意如图3所示,图3中所示的通信系统包括UE31、TRP32、第一PUSCH33和第二PUSCH34。
其中波束的标识方式包括:波束ID(Beam ID);同步信号块(Synchronous Signal Block,SSB)ID;以及信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)ID。
(4)关于波束失败恢复过程简介:
当UE的下行波束发生失败的时候,UE会触发波束失败恢复请求过程(beam failure recovery request procedure)。
对于非竞争的波束恢复请求,UE会触发非竞争的随机接入过程,UE会根据网络侧配置发送随机接入前导码(preamble),并在网络侧指定的用于波 束恢复的资源上(例如:特定的PDCCH资源)接收网络侧的反馈信息(例如:小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)调度的物理下行控制信道(Physical Downlink Control Channel,PDCCH))。当UE接收到网络对于该波束失败恢复请求的反馈信息后,UE判断该小区对应的(服务)波束恢复成功。
对于竞争的波束恢复请求,UE会触发基于竞争的随机接入过程。
在非竞争的随机接入过程,当用户设备(User Equipment,UE)成功接收到随机接入响应消息和收到带宽部分(Bandwidth Part,BWP)变换(switching)命令时,UE如何处理BWP变换过程是目前需要解决的问题。

    第一变换模块,用于将变换后的BWP用于RLM测量的参考信号变换为第一参考信号,所述第一参考信号为网侧络配置的所述变换后的BWP的RLM测量的参考信号。
  12. 根据权利要求8所述的UE,其中,
    当所述非竞争的随机接入过程为波束失败恢复请求触发的,所述随机接入完成消息为物理下行控制信道PDCCH承载的,且所述随机接入完成消息包含所述UE的小区无线网络临时标识C-RNTI;或者
    当所述非竞争的随机接入过程为非波束失败恢复请求触发的,所述随机 接入完成消息为随机接入响应消息,其中所述随机接入响应消息指示出随机接入请求标识。
  13. 根据权利要求12所述的UE,其中,所述接收模块进一步用于:在波束失败恢复请求反馈资源上接收随机接入完成消息。
  14. 根据权利要求8所述的UE,还包括:
    第二变换模块,用于当在所述UE发送物理随机接入信道PRACH时将第一BWP变换为第二BWP时,将所述第二BWP变换为所述第一BWP,所述第一BWP为发送所述PRACH之前的BWP。
  15. 一种用户设备,包括:处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序,所述计算机程序被所述处理器执行时实现如权利要求1至7中任一项所述的带宽变换的方法的步骤。
