Abstract: In one disclosure of the present invention, a method is provided for receiving an enhanced physical downlink control channel (EPDCCH) from a small cell having low transmission power. The receiving method may comprise the steps of: receiving EPDCCH-PRB set information including information about a physical resource block (PRB) that will receive the EPDCCH from the small cell; and determining a subframe that will be received by the EPDCCH from the small cell on the PRB checked by the EPDCCH-PRB set information. Here, the subframe that may be received by the EPDCCH from the small cell may be determined so as not to overlap a subframe transmitted by the EPDCCH by means of one or a plurality of neighboring cells.

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.

In a method of transmitting control information and apparatus therefor, the present invention includes receiving a PDCCH (physical control shared channel) having HARQ-ACK resource indication information in a first cell among a plurality of cells, receiving a first PDSCH (physical downlink shared channel) corresponding to the PDCCH in a second cell among a plurality of the cells, and transmitting HARQ-ACK for the first PDSCH through one of a first PUCCH (physical uplink control channel) format and a second PUCCH format. If the first cell is PCell (primary cell), the HARQ-ACK resource indication information indicates a resource of the first PUCCH format only. If the first cell is SCell (secondary cell), the HARQ-ACK resource indication information indicates one of the resource of the first PUCCH and a resource of the second PUCCH format.

Abstract: A disclosure of the present specification provides a method for executing power control by a user equipment (UE). The method may include the steps of: determining a first amount of power for transmitting a first uplink control information (UCI) by a user equipment (UE) set to have a dual connectivity with a first cell group and a second cell group; and determining a second amount of power for transmitting a second UCI. Herein, when the first UCI includes HARQ-ACK but the second UCI does not include HARQ-ACK, the determination of the first amount of power may have a priority over the determination of the second amount of power.
