Abstract: One embodiment of the present specification discloses an uplink transmission method in a multi-cell environment in which a single uplink resource is shared. The method may comprise: receiving control information that configures an uplink control channel and an uplink shared channel so that the uplink control channel and the uplink shared channel are not simultaneously transmitted on the same one uplink subframe, wherein the single uplink resource is shared by a first cell and a second cell; selecting any one of the uplink control channel and the uplink shared channel if a first Scheduling Request (SR) for the first cell and Uplink Control Information (UCI) for the second cell are requested to be simultaneously transmitted on the same subframe through the uplink control channel and the uplink shared channel, respectively; sending the selected channel on the uplink subframe.

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.
