Method of transmitting scheduling information in TDD system
First Claim
1. A method of performing hybrid automatic repeat request (HARQ) by a user equipment in a time-division-duplex (TDD) mobile communication system, the method comprising:
- receiving configuration information of a radio frame from a base station, the configuration information indicating which subframe in the radio frame is reserved for uplink or downlink;
receiving data over a plurality of downlink sub frames from the base station;
detecting an error from the received data; and
transmitting an acknowledgement/non-acknowledgement (ACK/NACK) signal corresponding to the detection of an error from the data received over an uplink subframe to the base station, the uplink subframe being configured by the configuration information,wherein the radio frame is configured by the table as follows;

Abstract
A method of transmitting scheduling information in time-division-duplex (TDD) system is provided. The method comprises configuring a radio frame, the radio frame comprising at least one downlink subframe and at least one uplink subframe, wherein a downlink subframe is reserved for downlink transmission and an uplink subframe is reserved for uplink transmission, and transmitting scheduling information on a downlink control channel in a downlink subframe, the scheduling information comprising an uplink indicator and uplink resource assignment, the uplink indicator indicating which at least one uplink subframe the uplink resource assignment is valid for. Data can be efficiently transmitted by using an uplink indicator which indicates a specific location of a subframe.
