Abstract: First downlink scheduling information for a first subframe and second downlink scheduling information for a second subframe can be transmitted and received in the first subframe. A first type downlink data channel can be transmitted and received in the first subframe according to the first downlink scheduling information, and a second type downlink data channel can be transmitted and received in the second subframe according to the second downlink scheduling information. Each of the first subframe and the second subframe may comprise a downlink control region and a data region in a time domain. The first downlink scheduling information and the second downlink scheduling information can be transmitted and received in the downlink control region of the first subframe. The first type downlink data channel is transmitted and received in the data area of the first subframe, and the second type downlink data channel can be transmitted and received in the downlink control region of the second subframe. The data area of the first subframe and the downlink control area of the second subframe can be continuous with each other.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for transmitting control information and an apparatus therefor, the method comprising the steps of: detecting one or more PDSCHs on a plurality of cells, wherein the plurality of cells are divided into a first cell set having PCell and a first SCell, and a second cell set having one or more second SCells; and as feedback for the one or more PDSCHs, transmitting HARQ-ACK information over PUCCH, wherein when the one or more PDSCHs are detected only in the first cell set, the HARQ-ACK information contains only a HARQ-ACK response for the first cell set, and when the one or more PDSCHs are detected at least in the second cell set, the HARQ-ACK information contains HARQ-ACK responses for both the first and the second cell sets.

Abstract: A method for performing a power scaling is discussed. The method performed by a user equipment (UE) includes determining, by the UE configured with dual connectivity to a first cell group and a second cell group, a first power for transmitting a first uplink channel on a first subframe toward the first cell group; determining a second power for transmitting a second uplink channel on a second subframe toward the second cell group; and scaling down the second power for transmitting the second uplink channel if a maximum power is exceeded, wherein the first uplink channel includes a first physical random access channel (PRACH), wherein the second uplink channel includes a second PRACH, and wherein the scaling down is performed if the first subframe is overlapped with the second subframe.
