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.

The present application discloses a method for mapping a subband/miniband in a wireless communication system. Particularly, the method comprises the steps of: dividing a system frequency band into a plurality of physical resource units (PRU); mapping the plurality of physical resource units to physical resource units of a subband (PRUSB) in accordance with a 1st rule; and mapping the plurality of physical resource units to physical resource units of a miniband (PRUMB) in accordance with a 2nd rule, wherein said 1st rule and said 2nd rule contain factors for limiting the minimum value of the gap between subbands allocated to the system frequency band.

A method of transmitting a cell type information, which is transmitted by a base station in a wireless communication system, is disclosed. The present invention includes broadcasting a boundary point information (Z) between a cell identity of a public ABS (advanced base station) and a cell identity of a private ABS via an S-SFH SP3 (secondary-super frame header subpacket3). In this case, the boundary point information (Z) includes a range information of cell identity partitions partitioned by granularity of 10 sequences per segment and a total number of the cell identity partitions is 16.

The present invention relates to a method for transmitting and receiving data in a wireless communication system. The method for transmitting data in a wireless communication system, according to one aspect of the present invention, comprises a step in which a base station transmits downlink data to a first terminal which supports a first system via a first region of a frame, and transmits downlink data to a second terminal which supports a second system via a second region which follows the first region corresponding to a frame offset on a time axis, wherein the frame offset is an offset of the start point of the frame for the first system and the start point of the frame for the second system, and the first region includes 3+6 (the frame offset-1) OFDM symbols. Each independent claim uniquely identifies the distinct claimed features.

New multiplexing UL structures for supporting legacy system are provided. A 16m system of diversity mode can be multiplexed with 16e system in PUSC mode in FDM manner with the same tiles/permutation rules. A 16m system can be multiplexed with 16e system in AMC mode in FDM and/or TDM manner. The time length of multiplexed 16e PUSC packets and/or 16m packets can be extended to more than two sub-frames for UL coverage. A PRU for 16m system may consists of 16 sub-carriers by 6 OFDMA symbols, 18 sub-carriers by 6 OFDMA symbols, or 20 sub-carriers by 6 OFDMA symbols when FDM is used.

Disclosed are an apparatus and method for transmitting or receiving uplink power control information. According to the present invention, a transmitting antenna of a base station device transmits, to a terminal, a first message containing first information on the interference and noise levels of frequency partitions to which an uplink data channel and an uplink control channel are allocated. Here, the uplink data channel and the uplink control channel are allocated to different frequency partitions. The transmitting antenna can further transmit, to the terminal, information on frequency partitions to which the uplink data channel and the uplink control channel are allocated.
