摘要:
The present invention relates to a segment identifier detection method performed by a terminal if a segment being administrated by a base station in a wireless communication system has the frequency reuse factor of 3 and 2 at the same time. In particular, the method comprises: acquiring a cell identifier and a segment identifier corresponding to the cell identifier from a secondary advanced preamble (SA-preamble) that has been received from the base station; determining a frequency reuse factor of the base station; and if the frequency reuse factor is 2 and the obtained segment identifier is a third segment identifier, transforming the segment identifier corresponding to the cell identifier into a first segment identifier or a second segment identifier.

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.

A method for transmitting signal, at a mobile station, in a wireless communication system is provided. Inter-cell interference level control parameter information may be different for each frequency partition due to use of an FFR scheme. This method is advantageous in that, when uplink transmission is performed, system throughput and cell edge-user throughput are improved and inter-cell interference level control is efficiently performed, thereby improving a Signal to Interference plus Noise Ratio (SINR) at the receiving end.

A method and an apparatus for mapping a resource unit in a wireless communication system is provided. The method includes obtaining LCRU,FPi indicating the number of contiguous resource units (CRUs) of an ith frequency partition (FPi) and LDRU,FPi indicating the number of distributed resource units (DRUs) of the FPi and mapping physical resource units (PRU) of the FPi to CRUs of the FPi by the LCRU,FPi and after allocating the PRUFPi to the CRU, maps the remaining part of the PRUFPi to DRUs of the FPi. A frequency selective scheduling gain and a frequency diversity gain can be obtained.

A method and an apparatus of subchannelization is provided. The method includes receiving information indicating the number of physical resource unit (PRU) sets allocated to a subband from a base station, and mapping PRUs of a physical region to a subband PRU or a miniband PRU in a granularity of the PRU set according to the received information, wherein the subband PRU is allocated with at least one subband comprising a first number of contiguous PRUs, the miniband PRU is allocated with at least one miniband comprising a second number of PRUs, and the PRU set comprises PRUs whose number is equal to the number of PRUs included in one subband. Subchannelization can be effectively achieved while maintaining a frequency selective scheduling gain and a frequency diversity gain to the maximum extent possible.

A method and an apparatus of mapping a resource unit is provided. Physical resource units (PRUs) are divided into a plurality of PRU sets. The PRUs are mapped to a subband PRU or a miniband PRU in a granularity of the PRU set. The mapping is based on the greatest common divisor of the maximum number of PRU sets. The resource unit can be effectively mapped while maximizing a frequency diversity gain of a subband PRU and a miniband PRU.

A method and apparatus for mapping a resource unit in a wireless communication system is provided. The method includes obtaining a frequency partition (FP) count (FPCT), an size of FPi (FPS) for i>0, and subband (SB) count of FPi (FPSC) for i>0 (where FPi is an ith FP), obtaining a value KSB,FPi indicating an SB count for FPi and a value KMB,FPi indicating a miniband (MB) count for FPi on the basis of the FPCT, the FPS, and the FPSC, and mapping an SB PRU including a plurality of contiguous physical resource units (PRUs) and an MB PRU including a plurality of contiguous PRUs to each FP in a granularity of a PRU set on the basis of the values KSB,FPi and KMB,FPi. Each FP can obtain a frequency selective scheduling gain based on the SB and a frequency diversity gain based on the MB.
