Title:
METHOD AND SYSTEM FOR TRANSMITTING OR RECEIVING FEEDBACK IN WIRELESS COMMUNICATION SYSTEM SUPPORTING NB-IOT
Document Type and Number:
WIPO Patent Application WO/2020/067822
Kind Code:
A1
Abstract:
The present specification provides a method for receiving feedback from a base station by a terminal in a wireless communication system supporting narrowband-Internet of things (NB-IoT). Specifically, the terminal: receives a preconfigured uplink (UL) resource (PUR) configuration via RRC signaling from the base station; when the terminal is in an idle mode, transmits uplink data to the base station at a PUR; and receives feedback for the uplink data from the base station, wherein the feedback is configured to be received via an NPDCCH after a specific time after PUR transmission.
