Claim Text:
1. A method for transmitting uplink response signal, comprising: receiving downlink data transmitted by a base station via a primary component carrier and a secondary component carrier in a predetermined order; detecting the received downlink data to obtain indication information on correctly receiving the downlink data, wrongly receiving the downlink data, or no control information being received, and to allocate corresponding uplink resources according to the primary component carrier and secondary component carrier where the detected downlink data is present; arranging the indication information obtained through detecting according to the predetermined order of transmitting the downlink data by the base station to obtain an indication information sequence; generating an uplink response signal according to the indication information in the indication information sequence obtained at the corresponding secondary component carrier and a position and number of the correctly received indication information in the indication information sequence, and determining the uplink resources used to feed back the uplink response signal; and transmitting the uplink response signal to the base station by using the determined uplink resources, such that the base station determines the downlink data needing to be retransmitted according to the uplink response signal fed back in the uplink resources, wherein the generating an uplink response signal and determining the uplink resources used to feed back the uplink response signals comprise: determining the number of correctly received indication information in the indication information sequence obtained through detecting at the secondary component carrier; and generating an uplink response signal according to the position and number of the correctly received indication information in the indication information sequence if it is determined that the number of correctly received indication information obtained through detecting at the secondary component carrier is 1, and determining the uplink resources used to feed back the uplink response signals.
