Title:

METHOD FOR RELAYING DATA IN WIRELESS COMMUNICATION SYSTEM BASED ON TIME DIVISION DUPLEX

Document Type and Number:

WIPO Patent Application WO/2010/079951

Kind Code:

A3

Abstract:

A method of relaying data in a time division duplex (TDD)-based wireless communication system is provided. The method includes configuring a downlink subframe as a multicast/broadcast single frequency network (MBSFN) subframe, receiving downlink data in the MBSFN subframe; and relaying uplink data to a base station in an uplink subframe, wherein the downlink subframe is linked to the uplink subframe which is reserved to transmit an acknowledgement (ACK)/non-acknowledgement (NACK) signal for downlink data transmission in the downlink subframe. Accordingly, in the TDD-based wireless communication system, efficiency of resource allocation can be increased, and uplink ACK collision can be avoided.
