Title:
METHOD FOR TRANSMITTING UPLINK DATA THROUGH PRECONFIGURED UPLINK RESOURCE IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/167102
Kind Code:
A1
Abstract:
This specification relates to a method for transmitting uplink data through a preconfigured uplink resource (PUR) in a wireless communication system, and an apparatus therefor. A terminal, in a radio resource control (RRC) connected state, receives PUR configuration information including a PUR transmission time point from a base station; transitions from the RRC connected state to an RRC idle state; determines whether a timing advance (TA) related to uplink transmission timing is valid on the basis of a reference signal received power (RSRP) change of a specific reference signal, wherein the RSRP change is a difference value between a first RSRP value measured on the basis of point A and a second RSRP value measured on the basis of point B; and transmits the uplink data to the base station at a first PUR transmission time point on the basis of the determination result and the PUR configuration information.
