Embodiment 1

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

[0369] The network device explicitly configures K BFR processes for each bandwidth part of each serving cell of the terminal (or K BFR processes for all bandwidth parts), 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 a BFR procedure list related parameter, 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, Such as beam failure recovery procedure (BeamFailureRecoveryProcedure) parameters, each BFR process includes a BFD RS set, such as q0, the corresponding high-level parameters are failure detectio...

Embodiment 2

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

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

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

[0390] The specific signaling can be,

[0391] BeamFailureRecoveryProcedure ::= SEQUENCE {

[0392] …

[0393] ...

Embodiment 3

[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 for each bandwidth part of each serving cell of the terminal (or K BFR processes for all bandwidth parts), 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, predefined rules include but are not limited to the following methods:

[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 ...
