AI Technical Summary

Technical Problem

Existing wireless communication systems face challenges in efficiently managing collisions between beam failure recovery requests (BFRQ) and other uplink transmissions on secondary cells, leading to inadvertent dropping of other uplink communications.

Method used

Implementing a multiplexing rule-based approach for UEs to selectively transmit beam failure recovery requests (BFRQ) on secondary cells, allowing for simultaneous transmission with other uplink communications by evaluating collision detection and priority considerations.

Benefits of technology

Enables efficient beam failure recovery on secondary cells without inadvertently dropping other uplink communications, reducing transmission delays and improving communication reliability.

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, user equipment (UE) detects a collision between a beam failure recovery request (BFRQ) transmission and another uplink transmission to trigger beam failure recovery for a secondary cell on an uplink channel; and on an uplink channel, transmit at least one of the BFRQ transmission or the other uplink transmission based at least partially on a multiplexing rule. Many other aspects are provided.
