Title:
METHODS AND APPARATUSES FOR PHYSICAL UPLINK CONTROL CHANNEL TRANSMISSION IN CASE OF BEAM FAILURE
Document Type and Number:
WIPO Patent Application WO/2023/015555
Kind Code:
A1
Abstract:
Disclosed are methods and apparatuses for physical uplink control channel (PUCCH) transmission. An embodiment of the subject application provides a method performed by a user equipment. The method includes: receiving a configuration of two physical uplink control channel scheduling request (PUCCH-SR) resources for beam failure recovery request (BFRQ) transmission for a cell group when two beam failure detection reference signal (BFD-RS) sets and two new beam indication reference signal (NBI-RS) sets are configured for a cell of the cell group, wherein there is one-to-one association between the two PUCCH-SR resources and the two BFD-RS sets, and there is one-to-one association between the two BFD-RS sets and the two NBI-RS sets, in response to that only one of the two BFD-RS sets is failed, transmitting a BFRQ in one PUCCH-SR resource of the two PUCCH-SR resources according to an association between the two PUCCH-SR resources and the two BFD-RS sets, and in response to that the two BFD-RS sets are failed, initiating a random access (RA) procedure to transmit a BFRQ, wherein the cell is a primary cell (PCell) or a primary secondary cell (PSCell).
