    摘要: Provided are a method and apparatus for transmitting data in a wireless communication system. The method comprises the steps of: setting up a frame including both a control domain for transmitting scheduling information to a first terminal and a data domain for transmitting first data to the first terminal; and transmitting, to a second terminal, second data in the control domain. The frame comprises a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time domain. The control domain consists of a first number N (where N is any natural number equal to or less than 4) of OFDM symbols in the frame. The data domain consists of OFDM symbols other than a number N of OFDM symbols in the frame. The second data has a predetermined bit size.

    摘要: The present invention relates to a method for configuring a starting position of a control channel in a wireless communication system, and a terminal using the same. 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.

    摘要: A method is described for transmitting channel status information by a user equipment (UE) in a wireless communication system. A radio frequency (RF) signal is received from a plurality of downlink component carriers. Each downlink component carrier has a respective center frequency. A channel measurement result of at least one downlink component carrier from among the plurality of downlink component carriers is reported via an uplink. Downlink subframes available for measurement are contiguous on a downlink component carrier in an activated state. Downlink subframes available for measurement are non-contiguous on a downlink component carrier in a deactivated state.
