Method of transmitting scheduling information in TDD system

摘要

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.

1. A method of transmitting, by a base station, scheduling information in a time-division-duplex (TDD) mobile communication system using a plurality of radio frames that each include downlink subframes reserved for downlink and uplink subframes reserved for uplink, the method comprising:
transmitting, to a user equipment, scheduling information on a downlink control channel within a downlink subframe in a radio frame, the scheduling information comprising information on a position of at least one uplink subframe for which uplink resource is assigned from a position of the downlink subframe, information on a number of the at least one uplink subframe, and an uplink resource assignment, wherein the uplink resource assignment identifies a radio resource to be used for uplink data transmission in the at least one uplink subframe, and wherein a number of downlink subframes in the radio frame is less than a number of uplink subframes in the radio frame.
