Abstract: According to one embodiment of the present invention, a method of receiving a downlink signal by a machine type communication user equipment (MTC UE) in a wireless communication system can comprise obtaining frequency hopping information on a plurality of subbands included in a downlink band and repeatedly receiving the downlink signal via different subbands based on the frequency hopping information. In this case, the downlink band includes ⌊ N RB 6 ⌋ number of subbands each configured as 6 resource block (RB) size and ‘NRB’ corresponds to a size of the downlink band. If a remaining band which does not belong to the ⌊ N RB 6 ⌋ number of subbands and is smaller than 6 RB size exists in the downlink band, at least one of a lowest index RB, a highest index RB and an intervening RB between subband groups in the downlink band may be configured as the remaining band.

Abstract: In the present invention, a method for performing an uplink transmission in a wireless communication system and an apparatus for supporting the same are disclosed. Particularly, a method for transmitting an uplink control channel in a wireless communication system by a terminal may comprise receiving, from a base station, beam information regarding one or more beams for transmitting a physical uplink control channel (PUCCH), via a radio resource control (RRC) signaling; receiving, from the base station, beam indication information indicating a specific beam among the one or more beams using a medium access control-control element (MAC-CE); and transmitting, to the base station, the physical uplink control channel using the specific beam.

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: 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.

Abstract: Descriptions on the method and the apparatus for controlling uplink transmission power are provided. The method for controlling uplink transmission power comprises receiving a signal on a downlink channel, wherein the signal includes information on transmission power which indicates a power control mode, determining whether primary cell (PCell) and secondary cell (SCell) are asynchronous or synchronous, determining maximum transmission power for the SCell, using the information on transmission power, based on whether the PCell and the SCell are asynchronous or synchronous, and transmitting signal to the SCell based on the maximum transmission power for the SCell.

Abstract: The present invention determines a PUCCH resource based on which serving cell ACK/NACK information is related to, when a user device set as a plurality of serving cells transmits the ACK/NACK information. Moreover, if a PUCCH transmission time matches with a PUSCH transmission time, the present invention does not piggy back ACK/NACK information to PUSCH but transmits the ACK/NACK information through PUCCH.
