Abstract

Embodiments of the present invention provide an information transmission method and device, which relate to the field of communication technologies, so as to solve the problem that the use timing of a new beam indicated by a beam failure recovery request is not specified in the traditional technology, and the UE and the network device are not used for each channel or The problem of inconsistent understanding of the beam information of the signal. The method includes: receiving a response message of a beam failure recovery request from a network device; determining target beam information according to a first beam indicated by the beam failure recovery request; using the target beam information to transmit the first information within a first predetermined time; wherein , the starting point of the above-mentioned predetermined time is: when the UE receives the above-mentioned response message, or after the first time period after the UE receives the above-mentioned response message; the above-mentioned first time period is related to the target subcarrier interval. The present application is applied in beam failure recovery scenarios.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to an information transmission method and device. Background technique [0002] In a high-frequency communication system, due to the short wavelength of the wireless signal, 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 used , it will take longer. [0003] To solve 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 UE for the beam failure recovery request after receiving the beam failure recovery request . [0004] How...
