Abstract

The invention provides a beam failure recovery handling method, a terminal and network side equipment. The method comprises the following steps of sending a scheduling request (SR) to network side equipment when detecting that a beam failure recovery (BFR) request needs to be reported. By adopting the method, when the terminal detects that the BFR request needs to be reported, the scheduling request SR is triggered, so that the BFR request can be recognized and responded by the network side equipment in time, alternative beam information is sent in time, beam recovery is carried out, and the problems that uplink resources are insufficient, a random access process needs to be executed, and data transmission is interrupted are avoided.

Description

technical field [0001] The present invention relates to the field of wireless technologies, in particular to a beam failure recovery processing method, terminal and network side equipment. Background technique [0002] In a long term evolution (Evolved Long Term Evolution, LTE) system, the terminal physical layer performs quality monitoring on the current beam, and reports poor quality information (instance) to the media access control (Media Access Control, MAC) layer. Based on the beam failure recovery (Beam failure recovery, BFR) threshold and other information configured by the upper layer, the MAC layer decides that the terminal enters beam failure recovery, and further triggers BFR non-contention-free random access (Contention-Free Random Access, CFRA), BFR contention-free random access Entry (Contention Based Random Access, CBRA) and other processes. [0003] Wherein, when the terminal is judged to enter beam failure recovery through the MAC protocol layer, the beam ...
