Abstract

A method for transmitting an uplink control signal of a terminal in a wireless communication system and a terminal using the method are provided. The method comprises the steps of: setting a first physical uplink control channel (PUCCH) resource for a first antenna port; setting a second PUCCH resource for a second antenna port; and transmitting a same uplink control signal through the first and second antenna ports by using the first and second PUCCH resources, wherein the first and second PUCCH resources are orthogonal to each other.

First claim

What is claimed is:

1. A method for transmitting an uplink control signal of user equipment in a wireless communication system, the method comprising:
determining an explicit physical uplink control channel (PUCCH) resource; and
transmitting an uplink control signal by using the explicit PUCCH resource,
wherein the explicit PUCCH resource is used to transmit an acknowledgement/not-acknowledgement (ACK/NACK) for a physical downlink shard channel (PDSCH) without a corresponding enhanced-PDCCH (e-PDCCH), and
wherein the e-PDCCH is a control channel positioned in a data region to which the PDSCH is assigned.

2. The method of claim 1 , wherein the PDSCH without the corresponding PDSCH without the corresponding e-PDCCH is a PDSCH scheduled by semi-persistent scheduling.

3. The method of claim 2 , wherein the PDSCH without the corresponding PDSCH without the corresponding e-PDCCH is received through a primary cell.

4. A user equipment (UE), comprising:
a radio frequency (RF) unit which transmits or receives a radio signal; and
a processor connected with the RF unit,
wherein the processor determines an explicit physical uplink control channel (PUCCH) resource and transmits an uplink control signal by using the explicit PUCCH resource,
wherein the explicit PUCCH resource is used to transmit an acknowledgement/not-acknowledgement (ACK/NACK) for a physical downlink shard channel (PDSCH) without a corresponding enhanced-PDCCH (e-PDCCH), and
wherein the e-PDCCH is a control channel positioned in a data region to which the PDSCH is assigned.

5. The UE of claim 4 , wherein the PDSCH without the corresponding e-PDCCH is a PDSCH scheduled by semi-persistent scheduling.

6. The UE of claim 5 , wherein the PDSCH without the corresponding e-PDCCH is received through a primary cell.
