    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.

    摘要： A method for modifying a synchronous non-adaptive retransmission scheme to solve the limitation of the synchronous non-adaptive retransmission scheme is disclosed. A method for indicating not only the new data transmission but also the retransmission using a data scheduling message is disclosed. A method for determining whether there is an error in the ACK signal transmitted from a data reception end using another message to-be received later is disclosed. The retransmission method for a multi-carrier system includes: receiving a grant message including scheduling information for transmitting uplink data wherein a retransmission scheme for the uplink data is predetermined by a first retransmission scheduling, transmitting the uplink data according to the scheduling information and retransmitting the uplink data according to second retransmission scheduling by receiving the second retransmission scheduling information associated with the uplink data with retransmission request.

    摘要： Disclosed is a method whereby a channel quality indicator is fed back by a terminal in a multiple-antenna wireless communication system. More specifically, the method comprises the steps of: receiving reference signals corresponding to a plurality of data streams from a base station; using the reference signals to calculate a channel quality indicator; and transmitting the calculated channel quality indicator to the base station; and, in the step in which the channel quality indicator is calculated, the channel quality indicator is calculated under the assumption that at least one of the reference signals has been transmitted using wither the spatial-multiplexing technique or the transmit diversity technique, depending on the feedback setting of the terminal.

    摘要： A method for transmitting control information in uplink from a mobile terminal to a base station in a wireless mobile communication system is provided. In the method, when no data to be transmitted to the base station is present in the mobile terminal, Scheduling Request (SR) information and Channel Quality Indicator (CQI) information having a predetermined size or greater are multiplexed together and the multiplexed information is transmitted to the base station through a Physical Uplink Shared CHannel (PUSCH). This method prevents waste of uplink transmission resources while avoiding uplink data transmission delay.
