Method for transmitting control information and apparatus for same

摘要

A wireless communication system is disclosed. A method for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in TDD includes: generating a first HARQ-ACK (hybrid automatic repeat request-acknowledgement) set for a first cell using a value M; generating a second HARQ-ACK set for a second cell using the value M; and transmitting a bit value corresponding to a third HARQ-ACK set including the first HARQ-ACK set and the second HARQ-ACK set in an uplink subframe n, wherein M=max(M1, M2), max(M1, M2) representing a value being equal to or larger than not smaller between M1 and M2, wherein M1 corresponds to the number of downlink subframes corresponding to the uplink subframe n in the first cell, and M2 corresponds to the number of downlink subframes corresponding to the uplink subframe n in the second cell, wherein the first cell and the second cell have different UL-DL configurations.

1. A method for transmitting by a user equipment (UE) uplink control information in a wireless communication system operating in a time division duplex (TDD) and supporting carrier aggregation of a plurality of cells including a first cell and a second cell, the method comprising:
based on the first cell and the second cell having different uplink-downlink (UL-DL) configurations, determining a value M as a largest value of M1 or M2, M1 being a value according to an UL-DL configuration of the first cell and M2 being a value according to an UL-DL configuration of the second cell; obtaining hybrid automatic repeat request-acknowledgment (HARQ-ACK) responses for the first cell and the second cell using the value M; and transmitting at least one bit value corresponding to the obtained HARQ-ACK responses in an uplink subframe.
