    摘要: Provided are a method and an apparatus for performing random access in a wireless communication system. A terminal receives from a base station a physical downlink control channel (PDCCH) indication, which indicates an initiation of the random access with respect to a secondary cell (SCell), based on whether a cross-carrier scheduling is supported by the SCell; transmits a physical random access channel (PRACH) preamble to the base station through the SCell; and transmits a RACH response as a response to the PRACH preamble, based on whether the SCell supports the cross-carrier scheduling, wherein the SCell and a primary cell (PCell) comprises a carrier aggregation (CA) system, the PCell is a cell from which the terminal performs radio resource control (RRC) connection with the base station, and wherein the SCell is at least one cell from residual cells in the carrier aggregation excluding the PCell.

    摘要: A method and apparatus for controlling uplink transmit power in a wireless communication system are disclosed. The method includes determining an uplink transmit power for each of the plurality of transmission channels, and sequentially allocating the determined uplink transmit powers to the transmission channels in a descending order of predetermined priority levels of the transmission channels, within a maximum available transmit power of the user equipment. The priority levels of the transmission channels are predetermined so that control channels, a sounding channel, a data channel, and a bandwidth request channel have priority levels in a descending order.

    摘要: A frame transmission method in a wireless communication system comprises setting a primary frame including a multiplicity of primary sub-frames, setting a secondary frame including a multiplicity of secondary sub-frames, and transmitting the secondary frame, wherein each of the primary sub-frames and each of the secondary sub-frames consists of multiple OFDM symbols, the OFDM symbols included in the primary sub-frame and the OFDM symbols included in the secondary sub-frame have different CP (Cyclic Prefix) lengths from one another, and the primary sub-frames and the secondary sub-frames are all equal in length. It is an advantage of the invention that frames consisting of OFDM symbols with different CP lengths can coexist together. Moreover, when each of the sub-frames within one frame consists of multiple OFDM symbols with different CP lengths, even the sub-frames can coexist together.
