Abstract: A method and apparatus for transmitting a power headroom report (PHR) in a wireless communication system is provided. A user equipment (UE) transmits a first PHR for a first carrier group, which is configured by a first eNodeB (eNB), to a second eNB; and transmitting a second PHR for a second carrier group, which is configured by the second eNB, to the first eNB. Te first PHR and the second PHR include a PHR for a physical uplink control channel (PUCCH) regardless of whether simultaneous transmission of the PUCCH and a physical uplink shared channel (PUSCH) is configured or not.

Abstract: Provided are a method for determining the number of hybrid automatic repeat request (HARQ) processes in a carrier aggregated system configured with a plurality of serving cells, and an apparatus using such a method. The method receives data from a downlink subframe of a second serving cell, and transmits an ACK/NACK signal for the data from an uplink subframe of a first serving cell, wherein the first serving cell uses a first-type frame, the second serving cell uses a second-type frame, and the number of HARQ processes in the second serving cell are determined with respect to each subframe comprised in the second-type frame and on the basis of the number of downlink subframes comprised in each section comprising a set number of subframes.

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.
