Technology is disclosed for a relay node (RN) operable for backhaul beam failure recovery (BFR) in a fifth generation (5G) new radio (NR) integrated access and backhaul (IAB) network. The relay node can be configured to: decode a periodic reference signal for beam failure instance detection...
总的来说,BFD和Radio link failure的机制比较类似,都是根据RRC层配置的参考信号让L1去测量,拿测量值结合对应的门限,判断是否上报对应的failure;但是有所不同,RLF的描述主要在RRC层38.331,触发场景就是T310超时(连续收到L1 N310 consecutive 'out-of-sync' indications,开启T310,在T310超时前,没有收到N311个in sync...
When user isindooror moving, theradio linkbetween the UE and gNB is susceptible toblockageanddegradationof RF signal which can suddenlyinterruptthe communication link result inBeam Failure. So to detect theBeam failureat right time, the UE should have some mechanism to measure such sudden and rap...

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...
Finding the optimal beam pair and update time in 5G systems operating at mmWave frequencies is time-intensive and resource-demanding. This intricate procedure calls for the proposal of more intelligent approaches. Therefore, this work proposes a machine learning-based method for optimizing beam pair ...
Design and implementation of beam failure recovery in 5G In a 5G millimeter wave system, beam misalignment between a gNB and an UE may occur due to sudden fluctuations in the channel, user rotation, and so on. Th... G Cheng,X Zhu,C Liu - 《Application of Electronic Technique》 被引量...
This paper presents DeepIA, a deep learning solution for faster and more accurate initial access (IA) in 5G millimeter wave (mmWave) networks when compared to conventional IA. By utilizing a subset of beams in the IA process, DeepIA removes the need for an exhaustive beam search thereby ...
In this webinar, you will learn about single- and multi-user MIMO in 5G NR, as well as common beamforming techniques and scenarios. We will cover different techniques to estimate the channel or channel information for beamforming purpose, how the UE communicates the necessary information back to...
Massive MIMO is one of the key technologies that will make or break the 5G deployment, especially in mmwave frequencies. Due its complex nature, massive MIMO remains a challenge for infrastructure as well as handset designers. In this talk, we look at the challenges in beamforming during initia...
