US 2021/0282187 A1 · METHOD AND WIRELESS COMMUNICATION SYSTEM FOR HANDLING TIMER OPERATION

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Accordingly, the embodiments herein disclose a method for handling a timer operation in a wireless communication system (300). The method includes receiving, by a UE (100), a signaling message from a base station (200). The signaling message includes an information about acquired COT of the base station (200). Further, the method includes indicating, by the UE (100), about the acquired COT to a MAC layer from a physical layer. The physical layer indicates one of the base station (200) has acquired the COT for transmission and the base station (200) has missed a transmission opportunity due to a LBT failure.

Claims15

Dependent claims

A method for handling a timer operation in a wireless communication system (300), comprising:

determining, by a base station (200), whether a Channel Occupancy Time (COT) is started or ongoing;
and
performing, by the base station (200), one of:
sending a COT active indication to a User Equipment (UE) (100) indicating that the base station (200) has acquired the COT for transmission in response to determining that the COT is started or ongoing, and
sending a COT inactive indication to the UE (100) indicating that the base station (200) has missed a transmission opportunity due to a listen-before-talk (LBT) failure in response to determining that the COT is not started or ongoing.

A method for handling a timer operation in a wireless communication system (300), comprising:

receiving, by a User Equipment (UE) (100), a signaling message from a base station (200), wherein the signaling message comprises an information about acquired channel occupancy time (COT) of the base station (200);
and
indicating, by the UE (100), about the acquired COT information to a medium Access control (MAC) layer from a physical layer, wherein the physical layer indicates one of the base station (200) has acquired the COT for transmission and the base station (200) has missed a transmission opportunity due to a listen-before-talk (LBT) failure.

A User Equipment (UE) (100) for handling a timer operation in a wireless communication system (300), comprising:

a memory (130);
and
a processor (110), coupled with the memory (130), configured to:
receive a signaling message from a base station (200), wherein the signaling message comprises an information about acquired channel occupancy time (COT) of the base station (200);
and
indicate about the acquired COT information to a medium Access control (MAC) layer from a physical layer, wherein the physical layer indicates one of the base station (200) has acquired the COT for transmission using a COT active indication and the base station (200) has missed a transmission opportunity due to a listen-before-talk (LBT) failure using a COT inactive indication.
