Abstract

The present invention pertains to a wireless communication system. Particularly, the present invention relates to a method for transmitting uplink control information and an apparatus for the same, wherein the method comprises the steps of: selecting one uplink control channel resource corresponding to a plurality of HARQ-ACKs, from a plurality of uplink control channel resources; and transmitting a bit value corresponding to the plurality of HARQ-ACKs through the use of the selected uplink control channel resource.

Claims (458)

1. A method for a communication apparatus to transmit control information using an Acknowledgement/Negative Acknowledgement (AN) channel selection scheme, the method comprising:

transmitting two bits via a Physical Uplink Control Channel (PUCCH) resource based on an identified AN state set and a mapping rule of Table 1 below,

wherein the identified AN set including Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK)(0), HARQ-ACK)(1), HARQ-ACK)(2) and HARQ-ACK)(3) for multiple cells including a Primary Cell (PCell) and one or more Secondary Cells (SCells), and the multiple cells consists of 2 to 4 cells,
