Title:
METHOD FOR HANDLING PRE-CONFIGURED UL RESOURCES BASED ON LBT PROCEDURE IN WIRELESS COMMUNICATION SYSTEM AND A DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/031796
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling pre-configured UL resources based on LBT procedure in wireless communication system, the method comprising: receiving information for UL resource configuration from a network, in a state that the UE is configured with at least one serving cell operating in an unlicensed spectrum; performing LBT operation for transmission of uplink data by using the UL resource, wherein the UE starts counting a number of failures of the LBT operation once the UE is not allowed to use the UL resource for transmission of uplink data during the LBT operation, and when the number of failures of the LBT operation reaches to the maximum number of LBT failure, stopping using the UL resource.
