METHOD FOR RELAYING DATA IN WIRELESS COMMUNICATION SYSTEM BASED ON TDD

摘要

PURPOSE: A data relay method in a wireless communication system based on a TDD is provided to perform data relay without additional resource allocation for a repeater station, thereby preventing uplink ACK collision and improving effectiveness of the resource allocation. CONSTITUTION: A downlink data is received from a base station. The downlink data relays to at least one terminal. An uplink subframe is divided into linked uplink subframe transmitting ACK(acknowledgement)/NACK(non-acknowledgement) about downlink data and unlinked uplink subframe not being linked with the down link subframe. A relay subframe receiving or transmitting the downlink frame belongs to the unlinking uplink subframe.
