相关申请的交叉引用
本申请主张在2018年2月12日在中国提交的中国专利申请号No.201810147322.7的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,尤其涉及一种波束失败恢复的方法、终端设备及网络设备。
未来第五代(5Generation,5G)移动通信***中,为了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***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用户设备(User Equipment,UE)中部署。基站侧的多波束/多收发节点(Multi-beam/Multi-TRP)发送和接收,UE侧的Multi-beam发送和接收将会广泛应用。以新无线物理上行共享信道(New Radio Physical Uplink Sharing Channel,NR PUSCH)为例,上行链路可多波束传输。其中,波束的标识方式包括:波束标识ID、同步信号块(Synchronous Signal Block,SSB)ID、信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)ID。
5G***中可采用双重连接(Dual Connectivity,DC)架构,包括两个小区组,分别为主小区组(Master Cell Group,MCG)和辅小区组(Secondary Cell Group,SCG),该MCG对应于网络侧的主节点(Master Node,MN),该SCG对应于网络侧的辅节点(secondary node,SN)。具体的,该MCG包括主小区(Primary Cell,PCell)和辅小区(Secondary Cell,SCell),该SCG包括主辅小区(Primary Secondary Cell,PSCell)和SCell,而该PCell和PSCell又可统称为特殊小区(Special Cell,SpCell)。
在5G***中,UE可能只能支持一个比较小的工作带宽(如5MHz),而 网络侧的一个小区会支持比较大的带宽(如100MHz),该大带宽中的UE工作的小带宽部分可认为是带宽部分(Bandwidth Part,BWP)。从UE配置的角度,对于不同的UE功能,BWP可以作为是1个小区或1个小区下的BWP。网络侧可配置UE有1个或多个BWP,并通过激活或去激活BWP的方式变换UE可以工作的BWP。
当UE的PCell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(即beam failure recovery request procedure)。具体的,UE会在PCell发送随机接入前导码preamble,并在PCell上等待接收网络侧的反馈信息,该反馈信息可为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)信息;当UE接收到网络对于该波束失败恢复请求的反馈信息后,可判断该PCell对应的(服务)波束恢复成功。
然而,当引入SCell或BWP后,该BWP可为PCell下的BWP,也可为SCell下的BWP,SCell或BWP的波束也有可能发生波束失败,针对此情况目前尚未明确如何进行波束失败恢复,因此有必要提出一种针对SCell或BWP的波束失败恢复方法,以明确当UE在SCell或BWP发生波束失败时,如何恢复其在SCell或BWP上的波束。
