Abstract
A method of transmitting data in a wireless communication system is provided. The method includes transmitting downlink scheduling information regarding downlink radio resource allocation and uplink scheduling information regarding uplink radio resource allocation on a downlink control channel transmitting downlink data on a downlink data channel according to the downlink scheduling information and detecting an acknowledgement (ACK)/negative-acknowledgement (NACK) signal for the downlink data from a radio resource exclusively allocated to the ACK/NACK signal. According to the present invention when an error occurs in a downlink control channel due to deterioration of a channel condition the error can be promptly handled using an error detection protocol agreed between a user equipment and a base station. Therefore data can be transmitted with higher reliability.

Claim
1. A method of transmitting data in a wireless communication system, the method comprising:
transmitting, by a base station (BS), downlink scheduling information regarding downlink radio resource allocation and uplink scheduling information regarding uplink radio resource allocation to a user equipment (UE) on a downlink control channel, the uplink scheduling information including a downlink transmission indicator indicating whether the downlink scheduling information is transmitted or not;
transmitting, by the BS, downlink data to the UE on a downlink data channel based on the downlink scheduling information;
detecting, by the BS, a first transmission error in the uplink scheduling information by determining whether expected control signals, including an acknowledgement (ACK)/negative-acknowledgement (NACK) signal corresponding to the downlink data, are detected from an uplink data channel based on the uplink scheduling information or not; and
if the expected control signals are not detected from the uplink data channel, detecting, by the BS, a second transmission error in the downlink scheduling information by determining whether the expected control signals, including the ACK/NACK signal corresponding to the downlink data, are detected from an uplink control channel.', 'transmitting, by a base station (BS), downlink scheduling information regarding downlink radio resource allocation and uplink scheduling information regarding uplink radio resource allocation to a user equipment (UE) on a downlink control channel, the uplink scheduling information including a downlink transmission indicator indicating whether the downlink scheduling information is transmitted or not;', 'transmitting, by the BS, downlink data to the UE on a downlink data channel based on the downlink scheduling information;', 'detecting, by the BS, a first transmission error in the uplink scheduling information by determining whether expected control signals, including an acknowledgement (ACK)/negative-acknowledgement (NACK) signal corresponding to the downlink data, are detected from an uplink data channel based on the uplink scheduling information or not; and', 'if the expected control signals are not detected from the uplink data channel, detecting, by the BS, a second transmission error in the downlink scheduling information by determining whether the expected control signals, including the ACK/NACK signal corresponding to the downlink data, are detected from an uplink control channel.
2. The method of claim 1, wherein the downlink control channel is a physical downlink control channel (PDCCH).
3. The method of claim 1, wherein the uplink data channel is a physical uplink shared channel (PUSCH).
4. The method of claim 1, wherein the uplink control channel is a physical uplink control channel (PUCCH).
5. The method of claim 1, wherein the uplink control signals including at least one of a channel quality indicator (CQI), a scheduling request (SR), and an uplink multiplexing information indicator indicating whether a plurality of uplink control signals are multiplexed or not.
6. The method of claim 1, wherein the first transmission error or the second transmission error is detected by performing discontinuous transmission (DTX) detection on a reference signal for the uplink control signals.
7. The method of claim 1, wherein
the uplink control signals use fixed resources including at least one of a location of an uplink subframe, a location of a frequency resource, and a location of a single carrier frequency division multiple access (SC-FDMA) symbol.', 'the uplink control signals use fixed resources including at least one of a location of an uplink subframe, a location of a frequency resource, and a location of a single carrier frequency division multiple access (SC-FDMA) symbol.']
