Abstract: Provided are a method and device for transmitting MSG3 in a random access procedure in a wireless communication system. A user equipment (UE) determines a frequency resource for transmitting MSG3 in a random access procedure and transmits the MSG3 to a network via the frequency resource. The starting position of the frequency resource is the smallest physical resource block (PRB) of an active uplink (UL) bandwidth part (BWP), and the bandwidth of the frequency resource is the same as the bandwidth of an initial UL BWP.

Abstract: One disclosure of the present specification provides a user equipment method. The method comprises the steps of: receiving a time division duplex (TDD) uplink (UL)-downlink (DL) configuration from a frequency division duplex (FDD)-based primary cell; receiving downlink data from at least one secondary cell; determining an uplink subframe of the primary cell to transmit a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative-acknowledgement (NACK) for the received downlink data, which is transmitted from the at least one secondary cell, according to the TDD UL-DL configuration; and transmitting the HARQ ACK/NACK from the determined uplink subframe to the primary cell.

Abstract: A method and apparatus for handling overlap of multiple channels in a wireless communication system is provided. A user equipment (UE), which operates in half-duplex frequency division duplex (FDD), determines that a periodic uplink (UL) transmission collides with a physical downlink shared channel (PDSCH) reception in a subframe, and performs either the periodic UL transmission or the PDSCH reception in the subframe. When the periodic UL transmission corresponds to a semi-persistent scheduled (SPS) physical uplink shared channel (PUSCH), the PDSCH reception is performed.

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.
