Abstract: A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. If the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.

Abstract: The present invention relates to a method for managing information of on/off small cells in a small cell-based network system and apparatuses for supporting the same. As an embodiment of the present invention, a method for managing information on on/off small cells in a radio access system supporting small cells comprises the steps of: receiving a first message including cell state change information of a first cell corresponding to a small cell, which is changed to an on state or an off state, by a second cell; and transmitting a second message including the cell state change information to a UE by the second cell. At this time, the cell state change information may contain identification information of the first cell, on/off time information indicating a time when change to an on state or an off state is made, and on/off timer information indicating a time interval in which the change to the on state or the off state is made.
