    摘要: A method and apparatus of generating a ranging signal in a wireless communication system is provided. A mobile station (MS) generates a ranging code in which a covering code has been applied to each of a plurality of orthogonal frequency division multiple access (OFDMA) symbols, and maps the ranging code to a plurality of subcarriers constituting each of the OFDMA symbols. The ranging signal is generated by performing OFDMA modulation on each of the OFDMA symbols.

    摘要: A method and apparatus of allocating a ranging channel in a wireless communication system is provided. A base station (BS) allocates at least one first ranging channel, having a first structure, and at least one second ranging channel, having a second structure, to a ranging subframe. The first structure or the second structure can be one of the ranging channel structures of an IEEE 802.16e system. A number of orthogonal frequency division multiplexing (OFDM) symbols included in the first structure and a number of OFDM symbols included in the second structure differs from each other. And a guard time including at least one OFDM symbol is allocated between the at least one first ranging channel and the at least one second ranging channel.

    摘要: A method for multiplexing one or more multiple access regions is disclosed. The method for multiplexing one or more multiple access regions in a wireless access system comprises multiplexing the one or more multiple access regions so that a first base station and a second base station among a plurality of base stations which use one or more multiple access schemes together under a multi-cell environment use a single multiple access scheme in a predetermined resource region allocated to each of the first base station and the second base station; and transmitting multiplexing information obtained from the multiplexing the one or more multiple access regions to a mobile station included in a cell region of the plurality of base stations. As a user uses SC-FDMA scheme and OFDMA scheme together, it is possible to obtain a single carrier effect of the SC-FDMA system and flexibility of the OFDMA system on a time axis and a frequency axis.

    摘要: A method and apparatus of generating a ranging preamble code in a wireless communication system is provided. A mobile station (MS) receives ranging channel information, and generates the ranging preamble code by selecting one of a plurality of candidate ranging preamble codes based on the ranging channel information. The plurality of candidate ranging preamble codes are based on a Zadoff-Chu (ZC) sequence of which a length is NRP and a root index is rp, and The ranging channel information comprises at least one of a start root index r0 among root indices of the plurality of candidate ranging preamble codes and a control parameter y indicating the start root index.
