Abstract

The embodiment of the invention provides a beam failure information reporting method, a beam failure information receiving method, a terminal and network equipment. The beam failure information reporting method comprises the following steps: a terminal receives a first reference signal set sent by a first transmission receiving point TRP; when it is determined that the link quality is lower than a first preset threshold value according to the receiving quality of the reference signals in the first reference signal set, the terminal reports first information, and the first information is used for indicating related information of beam failure. According to the scheme of the invention, the problem of how to report the beam failure information by the terminal when the beam failure occurs in the TRP is solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for reporting and receiving beam failure information, a terminal and a network device. Background technique [0002] The beam failure recovery process generally includes: 1) the terminal detects beam failure; 2) the terminal identifies an alternative beam; 3) the terminal sends a beam recovery request (Beam Failure Recovery Request, BFRQ) to the base station; 4) the terminal monitors the response of the base station to the BFRQ. [0003] Among them, the way for the terminal to detect beam failure is: the terminal detects the reference signal set The quality of the reference signal in , where It is configured by the base station or determined according to the TCI-state of CORESETs. when When the quality of all reference signals in is lower than Qout,LR, a beam failure instance (beam failure instance) is counted. When the number of beam failure instances excee...
