Abstract

The present disclosure relates to a beam failure reporting method and device, and a storage medium, and belongs to the field of communication technologies. The method includes: determining, by a terminal, that a target secondary serving cell in the n accessed secondary serving cells has a beam failure, where n is a positive integer; sending, by the terminal, a first MAC CE signaling to a base station, wherein the first MAC CE signaling includes a beam failure indication message. The embodiment of the present disclosure provides a reporting scheme when a terminal has a beam failure in the secondary serving cell, and implements reporting of the beam failure of the secondary serving cell.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a beam failure reporting method, device, and storage medium. Background technique [0002] In a 5G NR (New Radio, new air interface) system, base stations and terminals can use beams to send and receive information. For example, the base station may send downlink control information of a PDCCH (Physical Downlink Control Channel, physical downlink control channel) to the terminal through a beam. [0003] When the terminal moves or the antenna direction of the base station changes, beam failure (beam failure) may occur in the beam configured by the base station for the terminal to receive downlink control information. Currently, the standard defines an RS set for detecting beam failure. When the terminal detects that the channel measurement parameters corresponding to all RSs in the RS set are lower than the first threshold, the terminal determ...
