METHOD FOR TRANSMITTING CONTROL INFORMATION AND APPARATUS FOR SAME

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and an apparatus for transmitting uplink control information in the wireless communication system, which supports carrier aggregation and operates by a TDD, and comprises the steps of: generating a first HARQ-ACK set with respect to a first cell by using an L1 value; generating a second HARQ-ACK set with respect to a second cell by using an L2 value; and transmitting bit values, which correspond to the first and second HARQ-ACK sets are transmitted through a PUSCH from a subframe n, wherein L1=min (M1, W) and L2=min (M2, W) when the value (W) of a UL DAI corresponding to the PUSCH is 1 or 2, and L1=L2=W when the value (W) of the UL DAI corresponding to the PUSCH is 3 or 4, wherein min (A, B) represents a smaller number from A and B, M1 corresponds to the number of downlink subframes that correspond to an uplink subframe n with respect to the first cell, M2 corresponds to a the number of downlink subframes that correspond to the uplink subframe n with respect to the second cell, wherein the first cell and the second cell have different UL-DL configurations.

1. A method for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in time division duplex (TDD), the method comprising:
generating a first hybrid automatic repeat request-acknowledgement (HARQ-ACK) set for a first cell using an L1 value; generating a second HARQ-ACK set for a second cell using an L2 value; and transmitting bit values corresponding to the first and second HARQ-ACK sets through a physical uplink shared channel (PUSCH) in a subframe n, wherein L1=min (M1, W) and L2=min (M2, W) when a value W of an uplink downlink assignment index (UL DAI) corresponding to the PUSCH is 1 or 2, wherein L1=L2=W when the value W of the UL DAI corresponding to the PUSCH is 3 or 4, wherein min (A, B) represents a smallest number from A and B, wherein M1 corresponds to the number of downlink subframes corresponding to the uplink subframe n on the first cell and M2 corresponds to the number of downlink subframes corresponding to the uplink subframe n on the second cell, and wherein the first cell and the second cell have different uplink-downlink configurations.
