Method and device for transmitting control information in a wireless communication system
The present invention relates to a wireless communication system. In more detail, in relation to a method for a terminal to transmit ACK/NACK in a wireless communication system, an ACK/NACK transmission method includes: receiving at least one Physical Downlink Shared Channel (PDSCH); transmitting at least one ACK/NACK corresponding to the at least one PDSCH through a plurality of Physical Uplink Control Channel (PUCCH) formats; and, when the at least one ACK/NACK is transmitted using a first PUCCH format, transmitting at least one ACK/NACK in an antenna port transmission mode set for a second PUCCH format.
1. A method for transmitting, by a user equipment, an Acknowledgement/Negative Acknowledgement (ACK/NACK) signal in a wireless communication system, comprising:
when a Physical Downlink Shared Channel (PDSCH) is received only on a primary cell and the user equipment is configured to a Physical Uplink Control Channel (PUCCH) format 3, transmitting an at least one ACK/NACK signal corresponding to the PDSCH using a first PUCCH format,
wherein the at least one ACK/NACK signal is transmitted using an antenna port transmission mode configured for the first PUCCH format, and
wherein the first PUCCH format is one of a PUCCH format 1a or a PUCCH format 1b.
2. The method of claim 1 , wherein the antenna port transmission mode for the first PUCCH format is configured by a radio resource control signal.
3. The method of claim 1 , wherein an antenna port transmission mode for the PUCCH format 3 is configured independently from the first PUCCH format.
4. The method of claim 1 , wherein the antenna port transmission mode is a single-antenna port mode.
5. The method of claim 1 , wherein the antenna port transmission mode is a SORTD (Spatial Orthogonal Resource Transmit Diversity).
6. An apparatus for transmitting an Acknowledgement/Negative Acknowledgement (ACK/NACK) signal in a wireless communication system, comprising:
a Radio Frequency (RF) unit configured to receive and transmit radio signals; and
a processor configured to control the RF unit, wherein the processor is further configured to:
when a Physical Downlink Shared Channel (PDSCH) is received only on a primary cell and the apparatus is configured to a Physical Uplink Control Channel (PUCCH) format 3, transmit an at least one ACK/NACK signal corresponding to the PDSCH using a first PUCCH format,
wherein the at least one ACK/NACK signal is transmitted using an antenna port transmission mode configured for the first PUCCH format, and
wherein the first PUCCH format is one of a PUCCH format 1a or a PUCCH format 1b.
7. The apparatus of claim 6 , wherein the antenna port transmission mode for the first PUCCH format is configured by a radio resource control signal.
8. The apparatus of claim 6 , wherein an antenna port transmission mode for the PUCCH format 3 is configured independently from the first PUCCH format.
9. The apparatus of claim 6 , wherein the antenna port transmission mode is a single-antenna port mode.
10. The apparatus of claim 1 , wherein the antenna port transmission mode is a SORTD (Spatial Orthogonal Resource Transmit Diversity).
11. A method for transmitting, by a user equipment, an Acknowledgement/Negative Acknowledgement (ACK/NACK) signal in a wireless communication system, comprising:
configuring the user equipment to a Physical Uplink Control Channel (PUCCH) format 3;
when a Physical Downlink Shared Channel (PDSCH) is received only on a primary cell, transmitting an at least one ACK/NACK signal corresponding to the PDSCH using a first PUCCH format,
wherein the at least one ACK/NACK signal is transmitted using an antenna port transmission mode configured for the first PUCCH format,
wherein the first PUCCH format is one of a PUCCH format 1a or a PUCCH format 1b, and
wherein the antenna port transmission mode is a SORTD (Spatial Orthogonal Resource Transmit Diversity).
12. An apparatus for transmitting an Acknowledgement/Negative Acknowledgement (ACK/NACK) signal in a wireless communication system, comprising:
a Radio Frequency (RF) unit configured to receive and transmit radio signals; and
a processor configured to control the RF unit, wherein the processor is further configured to:
configure the user equipment to a Physical Uplink Control Channel (PUCCH) format 3,
when a Physical Downlink Shared Channel (PDSCH) is received only on a primary cell, transmit an at least one ACK/NACK signal corresponding to the PDSCH using a first PUCCH format,
wherein the at least one ACK/NACK signal is transmitted using an antenna port transmission mode configured for the first PUCCH format,
wherein the first PUCCH format is one of a PUCCH format 1a or a PUCCH format 1b, and
wherein the antenna port transmission mode is a SORTD (Spatial Orthogonal Resource Transmit Diversity).
