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 present invention provides a beam failure recovery method, device, and terminal. The method includes: if a beam failure occurs to a terminal in a discontinuous reception DRX inactive state, judging whether it is necessary to delay the initiation of the beam failure recovery process; if it is not necessary to delay the initiation of the beam failure In the recovery process, the terminal directly initiates the beam failure recovery process; if it is necessary to delay the initiation of the beam failure recovery process, determine the initiation time of the beam failure recovery process and initiate the beam failure recovery process at the initiation time; this method can clarify that the terminal is inactive in DRX The specific behavior of the terminal in the case of beam failure occurs in the state, so as to ensure the integrity and realizability of the protocol.

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 (...
