BEAM FAILURE RECOVERY AND RADIO LINK FAILURE ASSOCIATION IN FIFTH GENERATION (5G) - NEW RADIO (NR)Techniques discussed herein can facilitate reduced frequency of triggering a RLF (Radio Link Failure) timer and/or a false RLF procedure via employing one or more mechanisms for associating BFR (...
接上篇结尾,如果遇到不能通过QCL/TCI修正beam的场景,UE就会发生Beam failure,之后就需要先进行beam failure recovery 的方式尝试恢复正常连接,BFD就是在NR中才出现的机制,FR2中由于频率更高,Beam的管理显得尤为重要,因而BFD/BFR机制通常会在FR2下才会开启,现在的FR1网络中基本都没有开启BFD功能,但这个机制还是比较重...
解析 答:1)Beamfailure检测2)新beam选择3)在目标beam上发送beamfailurerecovery请求4)监测目标beam的下行PDCCH,检测网络对于beamfailurerecovery请求的响应 2020年最新5G试题晋州某动通信有限公司二面试题(含答案) 温馨提示:同学们,经过培训学习,你一定积累了很多知识,现在请认真、仔细地完成这张试题吧。加油!
1 基站配置beamFailureRecoveryConfig时,使用beamFailureRecoveryConfig配置的RACH资源发起随机接入,基于非竞争的随机接入流程(CFRA)即UE发送MSG1,基站在BFR专属搜索空间内下发C-RNTI加扰的PDCCH(在新的下行波束),终端发送PUCCH HARQ-ACK,完成接入,BFR成功。

thereby resulting in a beam failure. Although 5G NR supports recovery from such beam failure using the BFR protocol, the re-selection process in this protocol can consume a lot of UE power and may also lead to service delays. However, if the BS uses a wider beam408, as shown in FIG.4...
