Title:
A method of transmitting control information, and a device for it
Document Type and Number:
Japanese Patent JP6046778
Kind Code:
B2
Abstract:
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 M value; generating a second HARQ-ACK set with respect to a second cell by using the M value; and transmitting bit values which correspond to the first and second HARQ-ACK sets from a subframe n, wherein M = max (M1, M2), and max (M2, M2) represents a bigger number from M1 and M2, wherein 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.
