Method for transmitting control information and apparatus therefor

摘要

The present invention relates to a wireless communication system. Specifically, the present invention relates to a method for transmitting uplink control information and an apparatus therefore, which includes 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 bit values corresponding to the plurality of HARQ-ACKs using the selected uplink control channel resource.

1. A method for transmitting uplink control information by a communication apparatus configured with a plurality of cells including a primary cell and a secondary cell in a wireless communication system, the method comprising:
selecting a PUCCH (Physical Uplink Control Channel) resource corresponding to HARQ-ACK (Hybrid Automatic Repeat reQuest-Acknowledgement)(0), HARQ-ACK(1) and HARQ-ACK(2) from a plurality of PUCCH resources, according to a relation including Table 1; and transmitting b(0)b(1) corresponding to the HARQ-ACK (0), the HARQ-ACK(1) and the HARQ-ACK(2) using the selected PUCCH resource, wherein the b(0)b(1) is given according to the relation including Table 1,TABLE 1HARQ-HARQ-HARQ-ACK(0)ACK(1)ACK(2)n(1)PUCCH, ib(0)b(1)ACKACKNACK/DTXn(1)PUCCH, 011ACKNACKNACK/DTXn(1)PUCCH, 010NACKACKNACK/DTXn(1)PUCCH, 001NACKNACKDTXn(1)PUCCH, 000NACK/DTXNACK/DTXACKn(1)PUCCH, 211NACK/DTXNACK/DTXNACKn(1)PUCCH, 200 where the HARQ-ACK(0) and the HARQ-ACK(1) indicate ACK/NACK(Negative ACK)/DTX(Discontinuous Transmission) responses to data blocks related to a first cell, the HARQ-ACK(2) indicates ACK/NACK/DTX response to a data block related to a second cell, n(1)PUCCH, i (i=0, 1, 2) indicates the plurality of PUCCH resources, n(1)PUCCH,0 indicates a PUCCH resource linked to a PDCCH (Physical Downlink Control Channel) on the first cell, and n(1)PUCCH,2 indicates a PUCCH resource linked to a PDCCH on the second cell.
