Abstract

The embodiment of the invention provides an information transmission method and device, relates to the technical field of communication, and aims to solve the problem that UE (User Equipment) and network equipment have inconsistent understanding on beam information of each channel or signal due to the fact that the use opportunity of a new beam indicated by a beam failure recovery request is not stipulated in the traditional technology. The method comprises the following steps: receiving a response message of a beam failure recovery request from network equipment; determining target beam information according to a first beam indicated by the beam failure recovery request; and transmitting the first information by using the target beam information within a first predetermined time, wherein the starting point of the predetermined time is when the UE receives the response message, or after a first duration after the UE receives the response message; the first duration is related to a target subcarrier interval. The method is applied to a beam failure recovery scene.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an information transmission method and device. Background technique [0002] In a high-frequency communication system, since the wavelength of the wireless signal is short, it is easy to cause communication interruption due to signal blocking, user equipment (User Equipment, UE) movement, etc. At this time, if the wireless link reconstruction in the traditional technology is adopted , it takes longer. [0003] In view of this problem, the traditional technology mainly solves it by introducing a beam failure recovery (Beam Failure Recovery, BFR) mechanism. Specifically, for the secondary cell (Secondary cell, Scell) BFR mechanism, after the UE sends a beam failure recovery request to the network device, the network device sends a response message to the beam failure recovery request to the UE after receiving the beam failure recovery request . [0004] Howe...
