Abstract
The present invention relates to a wireless communication system. Specifically, the present invention relates to a method for transmitting uplink control information and to an apparatus therefor. The present invention relates to a method comprising the steps of: selecting one uplink control channel resource corresponding to a plurality of HARQ-ACKs from among a plurality of uplink control channel resources; and transmitting a bit value corresponding to the plurality of HARQ-ACKs using the selected uplink control channel resource, and to an apparatus therefor.
Claims14
A method for transmitting uplink control information when a plurality of cells including a primary cell and a secondary cell are configured in a wireless communication system, the method comprising:
- selecting one PUCCH (Physical Uplink Control Channel) resource pair corresponding to a plurality of HARQ-ACKs from among a plurality of PUCCH resource pairs for PUCCH format 1b;
- and
- transmitting a bit value corresponding to the plurality of HARQ-ACKs using the selected PUCCH resource pair through multiple antennas,
- wherein the plurality of PUCCH resource pairs includes resources shown in the following table,
- PUCCH resource pair #1
- PUCCH resource pair #2
- TX #N
- IMPP
- EXP1
- TX #M
- IMPP+1
- EXP2
- wherein TX #N and TX #M respectively denote antenna ports N and M, IMP denotes a PUCCH resource linked to a lowest CCE (Control Channel Element) index nCCE,P corresponding to a PDCCH (Physical Downlink Control Channel) relating to a PDSCH (Physical Downlink Shared Channel) in the primary cell, IMPP+1 represents a PUCCH resource linked to nCCE,P+1, and EXP1 and EXP2 represent PUCCH resources configured by a higher layer.
A communication apparatus configured to transmit uplink control information when a plurality of cells including a primary cell and a secondary cell are configured in a wireless communication system, the communication apparatus comprising:
- an RF unit;
- and
- a processor,
- wherein the processor is configured to select one PUCCH resource pair corresponding to a plurality of HARQ-ACKs from among a plurality of PUCCH resource pairs for PUCCH format 1b and to transmit a bit value corresponding to the plurality of HARQ-ACKs using the selected PUCCH resource pair through multiple antennas,
- wherein the plurality of PUCCH resource pairs includes resources shown in the following table,
- PUCCH resource pair #1
- PUCCH resource pair #2
- TX #N
- IMPP
- EXP1
- TX #M
- IMPP+1
- EXP2
- wherein TX #N and TX #M respectively denote antenna ports N and M, IMP denotes a PUCCH resource linked to a lowest CCE index nCCE,P corresponding to a PDCCH relating to a PDSCH in the primary cell, IMPP+1 represents a PUCCH resource linked to nCCE,P+1, and EXP1 and EXP2 represent PUCCH resources configured by a higher layer.
