Title:
BEAM DETECTION METHOD AND BEAM DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/253703
Kind Code:
A1
Abstract:
Provided are a beam detection method and a beam detection device, wherein same are used for further detecting the state of the current beam when a beam failure occurs in the current beam, and continuing to use the current beam for data transmission when the state of the current beam meets a condition in order to reduce handover latency. The method comprises: a UE acquiring a first configuration parameter; the UE measuring one or more first reference signals (RS) to obtain a first detection result; when the UE determines, according to the first detection result and the first configuration parameter, that the state of the current beam indicates a beam failure, the UE determining, according to first information, whether a trigger condition is met, wherein the first information comprises the first configuration parameter and/or the first detection result; and if the first information meets the trigger condition, the UE continuing to measure one or more first RSs to obtain a second detection result, wherein if the second detection result meets a first pre-set condition, the UE continues to use the current beam for data transmission.
