METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a method and apparatus for transmitting/receiving data in a wireless communication system. The method includes: a terminal transmitting a coverage enhancement request or capability information for the terminal; a base station determining a channel setting for the terminal based on the transmitted request or information; and transmitting downlink data and performing random access on the basis of the determined channel setting. Namely, a scheme for adaptively transmitting and receiving data in consideration of the coverage of the terminal is proposed.

主权项

1. A method of a terminal transmitting and receiving data in a wireless communication system, the method comprising:
determining a coverage extension level; checking a channel configuration regarding the terminal determined by a base station (BS) according to the determined extension level; and transmitting and receiving data according to the checked channel configuration, wherein the channel configuration includes a setting regarding a physical broadcast channel (PBCH) and a repetition number or repetition period of a varied PBCH with respect to the PBCH, wherein the channel configuration includes a setting of a physical random access channel (PRACH), and wherein the setting of the PRACH includes information on a period having a value longer than a PRACH configuration period regarding a legacy terminal or information on a repetition number of a PRACH varied according to a coverage extension level of the terminal.
