Abstract

An RLM adjustment and/or BFD adjustment method and device are provided. The method includes: obtaining first information and/or parameters configured by a network side, the first information including one or more of the following: a measurement result of a terminal, status information of the terminal, environment information, and network coverage information, the parameters configured by the network side being used for determining whether to perform RLM measurement and/or BFD detection adjustment; and determining, according to the first information and/or the parameters configured by the network side, whether to perform the RLM measurement and/or BFD detection adjustment.

First claim

What is claimed is:

1. A Radio Link Monitor (RLM) adjustment and/or Beam Failure Detection (BFD) adjustment method, applied to a terminal in a connected state, and comprising:
obtaining first information, the first information comprising: a measurement result of the terminal; and
determining, according to the first information, whether to perform RLM measurement adjustment and/or BFD detection adjustment,
wherein the determining, according to the first information, whether to perform RLM measurement adjustment and/or BFD detection adjustment comprises:
determining, according to a measurement result of a current cell and a preset threshold, whether to perform the RLM measurement and/or BFD detection adjustment of the current cell, and in response to the measurement result of the current cell being greater than or equal to a nineteenth threshold, performing RLM measurement relaxation and/or BFD detection relaxation of the current cell;
wherein the measurement result of the current cell comprises a reference signal receiving power (RSRP), a reference signal receiving quality (RSRQ), a signal to noise and interference ratio (SINR), and a channel quality indicator (CQI).

2. The method according to claim 1 , wherein the determining, according to a measurement result of a current cell and a preset threshold, whether to perform the RLM measurement adjustment and/or BFD detection adjustment comprises:
in response to that the measurement result of the current cell and the preset threshold satisfy a fourth condition, performing RLM measurement relaxation and/or BFD detection relaxation;
or
in response to that the measurement result of the current cell and the preset threshold satisfy a sixth condition, performing normal RLM measurement and/or normal BFD detection;
or
in response to that the measurement result of the current cell and the preset threshold satisfy an eighth condition, performing RLM measurement enhancement and/or BFD detection enhancement.

3. The method according to claim 2 , wherein
the fourth condition comprises one of the following:

or
the sixth condition comprises one of the following:
the measurement result of the current cell is less than or equal to or greater than a twenty-fourth threshold;
the measurement result of the current cell is less than or equal to or greater than the twenty-fourth threshold within a twenty-fourth preset time;
the measurement result of the current cell remains less than or equal to or greater than the twenty-fourth threshold within the twenty-fourth preset time;
the measurement result of the current cell is less than or equal to or greater than the twenty-fourth threshold, and the measurement result of the current cell is not greater than or not less than a twenty-fifth threshold within a twenty-fifth preset time;
the measurement result of the current cell is less than or equal to or greater than the twenty-fourth threshold, and the measurement result of the current cell remains not greater than or not less than the twenty-fifth threshold within the twenty-fifth preset time;
a change in the measurement result of the current cell within a twenty-sixth preset time is greater than or equal to or less than a twenty-sixth threshold;
the change in the measurement result of the current cell within the twenty-sixth preset time is greater than or equal to the twenty-sixth threshold, and no change in the measurement result of the current cell within a twenty-seventh preset time is less than or equal to a twenty-seventh threshold; and
the change in the measurement result of the current cell within the twenty-sixth preset time is greater than or equal to the twenty-sixth threshold, and a change in the measurement result of the current cell within a twenty-eighth preset time is greater than or equal to a twenty-eighth threshold;
or
the eighth condition comprises one of the following:
the measurement result of the current cell is less than or equal to a twenty-ninth threshold;
the measurement result of the current cell is less than or equal to the twenty-ninth threshold within a twenty-ninth preset time;
