Abstract: Provided are a method and a device for allocating a resource for an uplink control channel in a wireless communication system. The method for allocating a resource for an uplink control channel in a wireless communication system comprises: receiving at least one downlink subframe; and allocating a physical uplink control channel (PUCCH) resource for transmitting an acknowledgement/not-acknowledgement (ACK/NACK) for the at least one downlink subframe, wherein the PUCCH resource is allocated on the basis of a control channel element of a control channel for scheduling each of the at least one downlink subframe, and if a particular subframe that satisfies a particular condition is included in the at least one downlink subframe, a control channel element included in the special subframe is excluded from the control channel element used to allocate the PUCCH resource.

Abstract: Disclosed are a method for performing coordinated beamforming in a wireless access system, and an apparatus for the method. More particularly, the method for performing coordinated beamforming in a wireless access system comprises: a step in which a terminal receives, from a base station, time unit information for scheduling coordinated beamforming, a step in which the terminal receives, from the base station, a downlink signal having a predetermined transmission pattern on a time-unit basis for scheduling coordinated beamforming; a step in which the terminal demodulates the downlink signal using a reference signal transmitted from the base station; and a step in which the terminal removes an interference signal transmitted from a neighboring base station using the same downlink signal, from among the received downlink signals, that was received in different antenna modes. The antenna mode of the terminal can be switched according to a predetermined pattern on a time-unit basis for scheduling coordinated beamforming.
