METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION |
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 an uplink control signal in a carrier aggregation-based wireless communication system, the method comprising a step of receiving, at one or more cells from among a plurality of cells, one or more downlink signals in subframe #(n−k); and a step of transmitting, in subframe #n, an uplink control signal including information on the acknowledgement to the one or more downlink signals. The bit number of the information on the acknowledgement corresponding to a specific cell from among the plurality of cells in the subframe #(n−k) is given as a first value according to the transmission mode of the specific cell if the subframe #(n−k) is a first subframe, and given as a predetermined second value if the subframe #(n−k) is a second subframe. |

1. A method for transmitting an uplink control signal by a communication apparatus for which a plurality of cells is configured in a carrier aggregation-based wireless communication system, the method comprising:
receiving, in one or more cells from among the plurality of cells, one or more downlink signals in subframe #(n−k); and transmitting, in subframe #n, an uplink control signal including acknowledgement information on the one or more downlink signals, wherein the number of acknowledgement information bits corresponding to a specific cell from among the plurality of cells in the subframe #(n−k) is given as a first value according to a transmission mode of the specific cell when the subframe #(n−k) is a first subframe, and given as a predetermined second value when the subframe #(n−k) is a second subframe. |
