    摘要： A method and a user equipment (UE) for transmitting an aperiodic sounding reference signal (SRS) in a wireless communication system are discussed. The method according to an embodiment includes receiving an aperiodic SRS power offset parameter for the aperiodic SRS from a base station (BS) through a radio resource control (RRC) signaling; receiving common parameters for SRSs, including the aperiodic SRS, from the BS through the RRC signaling; setting a transmission power of the aperiodic SRS based on the aperiodic SRS power offset parameter and the common parameters; and transmitting the aperiodic SRS to the BS based on the transmission power of the aperiodic SRS. The aperiodic SRS power offset parameter is a non-common parameter used for transmitting the aperiodic SRS but not a periodic SRS which is included in the SRSs.

    摘要： A method of allocating control information in a wireless communication system is provided. The method includes: allocating essential control information of a first system to a first sub-frame in a frame including a plurality of sub-frames each of which comprises a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and allocating essential control information of a second system to an nth sub-frame in a fixed position from the first sub-frame (where n is an integer satisfying n>1). Accordingly, in a frame supporting heterogeneous systems, essential control information can be fixedly allocated to a specific position while maintaining the number of system switching points, at which switching occurs between the systems, to one even if a radio resource allocation amount changes between the systems, and thus the essential control information that must be received by all user equipments can be effectively provided without the increase of overhead.

    摘要： A method and device for transmitting a power headroom report (PHR) by a user equipment (UE) in a communication system supporting a plurality of carriers. The method includes transmitting, to an eNode B (eNB), a power headroom report (PHR) related to the plurality of carriers configured for the UE. The power headroom report (PHR) comprises a first type power headroom (PH) and a second type power headroom (PH). While the first type power headroom (PH) is calculated for a power headroom report (PHR) related to a primary carrier and a non-primary carrier, the second type power headroom (PH) is calculated for a power headroom report (PHR) related to only the primary carrier. The second type power headroom (PH) is calculated for case of simultaneous transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH).
