Abstract
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.
Claims12
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.
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.
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).
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).
