Title:

METHOD AND APPARATUS FOR TRANSMITTING OR RECEIVING DATA THROUGH UPLINK CARRIER IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/098710

Kind Code:

A1

Abstract:

The present disclosure relates to a method for transmitting or receiving data through a supplementary uplink carrier (SUL carrier) in a wireless communication system, the method comprising the steps of: receiving, from a base station, random access channel configuration (RACH configuration) information in the supplementary uplink carrier through a cell common signal of a downlink component carrier (downlink carrier: DL carrier); measuring a reference signal received power (RSRP) in the downlink component carrier; comparing the measured reference signal received power with a threshold for selection of the supplementary uplink carrier; and when the measured reference signal received power is smaller than the threshold, performing random access in the supplementary uplink carrier, wherein the threshold for the selection of the supplementary uplink carrier is included in the random access channel configuration information.
