Patent ID: 8891348

Claim:
A method for transmitting uplink control information when a plurality of cells including a primary cell and a secondary cell is configured in a wireless communication system, the method comprising: selecting a PUCCH (Physical Uplink Control Channel) resource corresponding to a plurality of HARQ ACKs (Hybrid Automatic Repeat request-Acknowledgements) from a plurality of PUCCH resources for PUCCH format 1b; and transmitting a complex value corresponding to the plurality of HARQ-ACKs using the selected PUCCH resource, wherein the plurality of HARQ-ACKs, PUCCH resources and bit values have the relationship represented by the following table, HARQ-ACK(0), HARQ- PUCCH PUCCH PUCCH ACK(1), HARQ-ACK(2) resource #1 resource #2 resource #3 N, N, N +1 0 0 N, N, A 0 0 −1 N, A, N +j 0 0 N, A, A 0 −1 0 A, N, N −j 0 0 A, N, A 0 +1 0 A, A, N −1 0 0 A, A, A 0 +j 0 D, D, N 0 0 +1 wherein HARQ-ACKs(0) and (1) indicate ACK(A)/NACK(N)/DTX(D) responses to data block(s) on a MIMO (Multiple Input Multiple Output) cell, HARQ-ACK(2) indicates an ACK(A)/NACK(N)/DTX(D) response to a data block on a non-MIMO cell, PUCCH resources #1 and #2 represent PUCCH resources linked to the MIMO cell for PUCCH format 1b, and PUCCH resource #3 represents a PUCCH resource linked to the non-MIMO cell for PUCCH format 1b.
