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.

Abstract: A method and apparatus for communicating with a long-term evolution in unlicensed spectrum (LTE-U) base station (BS) in a wireless communication system is provided. A user equipment (UE) receives a configuration of a potential transmission time unit (P-TTU), communicates with a first LTE-U BS of a first operator based on the configured P-TTU, and communicates with a second LTE-U BS of a second operator based on the configured P-TTU. The communication with the first LTE-U BS and the communication with the second LTE-U BS is multiplexed by time division multiplexing (TDM).

Abstract: Discussed is a method for transmitting a discovery signal. The method is performed by a cell of a base station and includes transmitting, to a user equipment (UE), measurement configuration information including a sub-frame offset, wherein the sub-frame offset indicates an offset between a secondary synchronization signal (SSS) and a channel-state information reference signal (CSI-RS) in a discovery signal; transmitting the SSS in the discovery signal on a first sub-frame; and transmitting the CSI-RS on a second sub-frame which is determined based on the sub-frame offset and the first sub-frame for the SSS in the discovery signal.
