Example Embodiment

[0368] Embodiment 1: The network device explicitly configures the BFR process and the BFD RS set included in each BFR.

[0369] The network device explicitly configures K BFR processes (or K BFR processes of all bandwidth parts) for each bandwidth part of each serving cell of the terminal, and each BFR process includes a BFD RS set. Wherein, each BFR process may correspond to the transmission of one TRP or multiple TRPs, or the transmission of the entire cell; K is a positive integer.

[0370] For example, all BFR procedures on a serving cell are configured by parameters related to a BFR procedure list, such as a beam failure recovery procedure list (BeamFailureRecoveryProcedureList), which contains multiple BFR procedures, and each BFR procedure is configured by a high-level parameter. For example, the beam failure recovery process (BeamFailureRecoveryProcedure) parameter, each BFR process also includes a BFD RS set, such as q0, and the corresponding high-level parameter is f...

Example Embodiment

[0387] Embodiment 2: The network device explicitly configures the BFR process and the CORESET group corresponding to each BFR process. Among them, a CORESET group contains at least one CORESET.

[0388] The network device explicitly configures K BFR processes (or K BFR processes for all bandwidth parts) for each bandwidth part of each serving cell of the terminal, and each BFR process configures a CORESET group, which can be determined by high-level parameters. It is represented by a control resource set list (controlResourceSetList); wherein, K is a positive integer.

[0389] The CORESET group includes: CORESETs corresponding to one or more CORESET indexes configured by the network device, or CORESETs with high-level parameters configured as specific values, for example, the high-level parameter may be a control resource collection pool index (CORESETpoolIndex).

[0390] The specific signaling can be:

[0391] BeamFailureRecoveryProcedure::=SEQUENCE{

[0392] …

Example Embodiment

[0414] Embodiment 3: The network device explicitly configures the number of BFR processes, and the terminal determines the corresponding CORESET group for the BFR process in a predefined manner.

[0415] The network device explicitly configures K BFR processes (or K BFR processes for all bandwidth parts) for each bandwidth part of each serving cell of the terminal, that is, only the number of BFR processes is configured, and K is a positive integer; the terminal A CORESET group is determined for each BFR process by predefined rules.

[0416] When the terminal detects that the RS associated with the CORESET group corresponding to any BFR process is lower than a certain threshold, it reports the BFR process index, or the CORESET group index or the BFD RS set index to the network device.

[0417] Optionally, the predefined rules include but are not limited to the following ways:

[0418] When one BFR process is explicitly configured for each bandwidth part, it can be pre-defined...

Abstract

The invention provides a beam failure processing method, a terminal and network equipment. The method comprises the following steps: acquiring K beam failure recovery (BFR) processes, and a beam failure detection reference signal (BFD) RS set or a control resource set CORESET group corresponding to the K BFR processes; wherein K is a positive integer; for each BFR process, beam failure processing is carried out according to reference signals in a BFD RS set corresponding to the BFR process or reference signals associated with a CORESET group; wherein the CORESET group comprises at least one CORESET, and the CORESET group comprises at least one CORESET. According to the invention, the problem of poor communication performance of the current beam failure processing method can be solved, and the transmission delay can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a beam failure processing method, terminal and network equipment. Background technique [0002] In a new radio interface (new radio, NR) system, when a high-frequency band is used for transmission, the physical channel and the physical signal can adopt a beamforming technology to improve data transmission quality. Through the beamforming technology, the network device side can concentrate the transmission power in a certain direction (for example, the direction where the terminal is located), so as to increase the power of the received signal. However, when the link between the network device side and the terminal is blocked, the receiving power of the terminal side will be greatly reduced, thereby causing a transmission (beam) failure event. NR defines a beam failure recovery mechanism, also called link recovery (link recovery) mechanism. The specific method ...
