图1示例性地示出了一个网络设备110和两个终端设备120,可选地,该无线通信系统100可以包括多个网络设备110,并且每个网络设备110的覆盖范围内可以包括其它数量的终端设备120,本申请 实施例对此不做限定。
可选地,该无线通信系统100还可以包括移动性管理实体(Mobility Management Entity,MME)、接入与移动性管理功能(Access and Mobility Management Function,AMF)等其他网络实体,本申请实施例对此不作限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
在NR(New Radio,新空口)Rel-15中,针对PCell(Primary Cell,主小区)或者PSCell(Primary Secondary cell,主辅小区)(统称为SpCell(Special Cell,特别小区)),标准化了BFR(Beam Failure Recovery,波束失败恢复)。UE可以通过随机接入的方式来告知基站使用哪个下行发送波束来发送RAR,从而恢复下行波束。NR RA(Random Access,随机接入)的随机接入前导码(Random Access Preamble)是逐个SSB(Synchronous Signal Block,同步信号块)配置的,UE首先通过对比参考信号接收功率(Reference Signal Received Power,RSRP)来选择满足阈值的SSB/CSI-RS(Channel State Information-Reference Signal,信道状态信息参考信号)索引,并使用该SSB上对应的前导码以及PRACH(Physical Random Access Channel,物理随机接入信道)资源来发送Msg1,也就是说,gNB收到前导码后,就可以确定用哪个SSB来反馈RAR(Radom Access Response,随机接入响应)。
波束失败恢复的总体流程可以包含如下一些步骤。
波束恢复检测(Beam failure detection)步骤,物理层通过测量CSI-RS和/或SS/PBCH(Synchronous Signal/Physical Broadcast Channel,同步信号/物理广播信道)块来判断对应的PDCCH(Physical Downlink Control Channel,物理下行控制信道)质量是否满足预定/配置的阈值(Hypothetical BLER(block error rate,块错误率)),若检测到波束失败(例如检测到的性能比该阈值差),就向媒体接入控制层MAC上报一个波束失败实例(beam failure instance)。对一个MAC实体来说,每当物理层上报一个波束失败实例,UE就会为相应的波束失败计数器BFI_COUNTER加1并重启波束失败检测定时器beamFailureDetectionTimer;若在波束失败检测定时器运行期间,该相应的波束失败计数器BFI_COUNTER达到设定的一个阈值,则认为波束失败,并进行随机接入过程。
新候选波束识别(New candidate beam identification)步骤,UE通过CSI-RS和/或SSB(SS/PBCH块)来选择新的满足上述预定/配置阈值的新的波束。如果没有选择到满足条件的新波束,则采用基于竞争的随机接入(contention-based random access)过程。
波束失败恢复请求发送(Beam failure recovery request transmission)步骤,UE选择一个新波束对应的PRACH来发起传输,或者通过PUCCH来上报其选择的新波束。
UE监测网络侧响应的步骤,UE监测gNB的对于波束恢复失败请求的响应(UE monitors gNB response for beam failure recovery request)。
在3GPP R16,引入了辅小区SCell的BFR,通过BFR MAC CE来指示该SCell发生了波束失败。
对于3GPP R16,辅小区SCell的BFR是通过MAC CE上报网络侧的,当没有可用的上行资源时会触发SR以请求网络侧分配上行资源。对于3GPP R17,不同于SCell BFR,的是,对于TRP BFR,每个小区可能会配置多个(例如两个)PUCCH资源,那么在这种情况下,当没有可用的上行资源来传输用于上报TRP BFR的MAC CE时,如何触发SR则是需要解决的技术问题。
