example 1

[0107] Step 1, the terminal performs a beam failure judgment;

[0108] The terminal performs beam failure judgment according to the existing beam failure judgment process. For example, beam failure detection involves two configuration parameters: the maximum number of beam failure instances beamFailureInstanceMaxCount, the beam failure detection timer beamFailureDetectionTimer, and a variable beam failure instance counter BFI_COUNTER. If BFI_COUNTE reaches beamFailureInstanceMaxCount while beamFailureDetectionTimer is running, the judgment beam fails.

[0109] Step 2, the terminal judges whether it is necessary to delay the initiation of the beam failure recovery process. The principle for the terminal to determine whether it is necessary to delay the initiation of the beam failure recovery process can be any of the following:

[0110] Method 1: Always without delay, the beam failure recovery process is initiated immediately upon beam failure.

[0111] Method 2: Always delay...

Abstract

The invention provides a beam failure recovery method and device and a terminal, and the method comprises the steps: judging whether a beam failure recovery process needs to be delayed or not if a terminal in a discontinuous reception (DRX) inactive state has a beam failure; if the beam failure recovery process does not need to be delayed, enabling the terminal to directly initiate the beam failure recovery process; if the beam failure recovery process needs to be delayed to be initiated, determining an initiation moment of the beam failure recovery process and initiating the beam failure recovery process at the initiation moment. According to the method, the specific behavior of the terminal under the condition of beam failure of the terminal in the DRX inactive state can be determined, so the integrity and realizability of a protocol are ensured.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a beam failure recovery method, device and terminal. Background technique [0002] In order to solve the power consumption problem, the LTE system adopts a DRX (Discontinuous Reception, discontinuous reception) working mode. In this working mode, the terminal periodically monitors the control channel, thereby achieving the purpose of power saving. [0003] The basic principle of DRX is as follows figure 1 As shown, where On duration (duration) indicates the time period during which the terminal monitors the control channel, during which the radio frequency channel is opened and continuously monitors the control channel; except for other times of On duration, the terminal is in a sleep state, and its radio frequency link will be blocked. Closed, no longer monitor the control channel, in order to achieve the purpose of power saving. OnDuration occurs periodically (...
