Timer configuration for new radio-unlicensed and new radio-shared spectrum

Abstract:

Timer configurations for new radio (NR) unlicensed (NR-U) and NR shared spectrum (NR-SS) operations are disclosed. In NR-U and NR-SS operations, certain event timers may be interrupted by a user equipment (UE) when it detects that its serving base station has failed a listen before talk (LBT) procedure, thereby losing access to the shared communication spectrum. When the UE detects a subsequent successful LBT, it resumes the progression of the event timer. In NR-SS operations, the UE may also interrupt the applicable timers either in all slots dedicated to another operator or in all slots in which the serving base station does not have transmission access.
