The method includes receiving duration information about a physical downlink control channel from the first orthogonal frequency division multiplexing (OFDM) symbol of a downlink subframe; and configuring a first OFDM symbol after OFDM symbols indicated by the duration information, as a starting point of an enhanced-physical downlink control channel. The downlink subframe includes a plurality of subcarriers in a frequency domain and 12 or 14 OFDM symbols in a time domain. The PDCCH includes the first N (N is a natural number of from 1 to 4) number of OFDM symbols of the downlink subframe. The duration information indicates the N number of OFDM symbols. The E-PDCCH comprises the starting point to the last OFDM symbol of the downlink subframe.

Abstract: A method, performed by a user equipment, is described for adjusting a transmit power for sounding reference signals (SRS) in a wireless communication system supporting a plurality of cells. A determination is made for each transmit power for a plurality of SRS to be transmitted on a subframe for a serving cell. If a total transmit power for the plurality of SRS to be transmitted on the subframe exceeds a maximum transmit power, the total transmit power is scaled for the plurality of SRS. The total transmit power for the plurality of SRS is scaled with a scaling factor parameter for the serving cell. Values of the scaling factor parameter are the same across serving cells.
