Patent ID: 8281201

Claim:
A method for retransmitting data in a wireless communication system, the method comprising: receiving a first uplink grant via a physical downlink control channel (PDCCH), the first uplink grant indicating resources for transmitting uplink data, wherein the first uplink grant is based on at least one first transmission parameter for transmitting the uplink data; transmitting the uplink data via a physical uplink shared channel (PUSCH) using the resources indicated by the first uplink grant; receiving an indication for retransmission of the uplink data via a physical hybrid automatic repeat request indicator channel (PHICH); identifying the existence of control information to be transmitted via the PUSCH with the retransmission of the uplink data; determining at least one second transmission parameter for transmitting the control information according to the at least one first transmission parameter for transmitting the uplink data; determining an amount of resources for transmitting the control information according to the determined at least one second transmission parameter; multiplexing retransmission data with the control information such that the control information and the retransmission data are transmitted using resources indicated by a second uplink grant; and transmitting the multiplexed retransmission data and control information on the PUSCH using the resources indicated by the second uplink grant.
