US 11,451,432 B2 · 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.

Dependent claims

A method of wireless communication, comprising:

initiating, by a user equipment (UE), an event timer in response to performance by the UE of an event, a response to which is associated with the event timer, wherein the event timer is identified within one or more event timers subject to an interruption operation;
detecting, by the UE, a failed listen before talk (LBT) procedure of a serving base station;
suspending, by the UE, a progression of the event timer in response to the failed LBT procedure;
monitoring, by the UE, for a result of a subsequent LBT procedure of the serving base station;
and
resuming, by the UE, the progression of the event timer in response to detection of the result as a successful LBT procedure.

3 more elements

An apparatus configured for wireless communication, comprising:

means for initiating, by a user equipment (UE), an event timer in response to performance by the UE of an event, a response to which is associated with the event timer, wherein the event timer is identified within one or more event timers subject to an interruption operation;
means for detecting, by the UE, a failed listen before talk (LBT) procedure of a serving base station;
means for suspending, by the UE, a progression of the event timer in response to the failed LBT procedure;
means for monitoring, by the UE, for a result of a subsequent LBT procedure of the serving base station;
and
means for resuming, by the UE, the progression of the event timer in response to detection of the result as a successful LBT procedure.

3 more elements

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

program code executable by a computer for causing the computer to initiate, by a user equipment (UE), an event timer in response to performance by the UE of an event, a response to which is associated with the event timer, wherein the event timer is identified within one or more event timers subject to an interruption operation;
program code executable by the computer for causing the computer to detect, by the UE, a failed listen before talk (LBT) procedure of a serving base station;
program code executable by the computer for causing the computer to suspend, by the UE, a progression of the event timer in response to the failed LBT procedure;
program code executable by the computer for causing the computer to monitor, by the UE, for a result of a subsequent LBT procedure of the serving base station;
and
program code executable by the computer for causing the computer to resume, by the UE, the progression of the event timer in response to detection of the result as a successful LBT procedure.

3 more elements

An apparatus configured for wireless communication, the apparatus comprising:

at least one processor;
and
a memory coupled to the at least one processor,
wherein the at least one processor is configured:
to initiate, by a user equipment (UE), an event timer in response to performance by the UE of an event, a response to which is associated with the event timer, wherein the event timer is identified within one or more event timers subject to an interruption operation;
to detect, by the UE, a failed listen before talk (LBT) procedure of a serving base station;
to suspend, by the UE, a progression of the event timer in response to the failed LBT procedure;
to monitor, by the UE, for a result of a subsequent LBT procedure of the serving base station;
and
to resume, by the UE, the progression of the event timer in response to detection of the result as a successful LBT procedure.
