Title:
BEAM FAILURE REPORT SENDING METHOD AND RECEIVING METHOD, USER EQUIPMENT, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/223426
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a beam failure report sending method and receiving method, user equipment (UE), and a network device, pertaining to the technical field of communications, and used for reporting, to a network device by multiplexing a first resource on a physical uplink control channel, a failure occurring on a downlink transmission beam for downlink transmission. The method comprises: UE generating a beam failure report comprising first indication information and candidate beam information, the candidate beam information being used to indicate to a network device one or more candidate downlink transmission beams determined by the UE; and the UE sending the beam failure report to the network device on a first resource of the physical uplink control channel, the first indication information being used to indicate to the network device that content transmitted by the UE on the first resource is a beam failure report, and the first resource being used by the UE to send a channel state information (CSI) report and/or a beam information report.
