    摘要: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for enabling a transmitter to transmit a sequence in a wireless communication system, and to an apparatus for the same. A sequence-transmitting method comprises the steps of: performing at least one of a complex conjugate operation and a reverse operation on a first sequence to generate a second sequence; mapping the second sequence to a plurality of subcarriers in an Orthogonal Frequency Division Multiple Access (OFDMA) symbol; and transmitting the OFDMA symbol to a receiver. The invention also relates to an apparatus for the sequence-generating method.

    摘要: The present invention relates to a broadband wireless access system, and more particularly, to a frame structure to which OFDM symbols having a cyclic prefix are transmitted. A method of constructing a frame in a broadband wireless access system according to one embodiment of the present invention comprises including one or more first subframes in the frame, the first subframes including a plurality of symbols having a cyclic prefix of a first length; and including one or more second subframes in the frame, the second subframes including a plurality of symbols having a cyclic prefix of a second length different from the first length, wherein the number of the first subframes and the number of the second subframes are determined considering an idle time for which effective symbols are not included in the frame.

    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.

    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.
