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.
Claims16
A method for transmitting an Acknowledgement/Negative Acknowledgement (ACK/NACK) signal by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, by the UE, a Physical Downlink Shared Channel (PDSCH) only on a primary cell, wherein the UE is configured with a Physical Uplink Control Channel (PUCCH) format 3;
- and
- transmitting, by the UE, an ACK/NACK signal for the PDSCH on the primary cell, based on a first PUCCH format which is one of PUCCH format 1a or PUCCH format 1b,
- wherein a number of antenna ports configured in an antenna port transmission mode for the first PUCCH format is independent from a number of antenna ports configured in an antenna port transmission mode for the PUCCH format 3.
A user equipment (UE) for transmitting an Acknowledgement/Negative Acknowledgement (ACK/NACK) signal in a wireless communication system, the UE comprising:
- a Radio Frequency (RF) unit configured to receive and transmit radio signal;
- and
- at least one processor configured to control the RF unit, wherein the at least one processor is further configured to:
- control the RF unit to receive a Physical Downlink Shared Channel (PDSCH) only on a primary cell,
- wherein the UE is configured with a Physical Uplink Control Channel (PUCCH) format 3;
- and
- control the RF unit to transmit an ACK/NACK signal for the PDSCH on the primary cell, based on a first PUCCH format which is one of PUCCH format 1a or PUCCH format 1b,
- wherein a number of antenna ports configured in an antenna port transmission mode for the first PUCCH format is independent from a number of antenna ports configured in an antenna port transmission mode for the PUCCH format 3.
