A method for transmitting or receiving an uplink signal is disclosed. If a user equipment is connected to a base station in accordance with a legacy system support mode, it performs permutation for an uplink signal on a frequency axis in accordance with a first rule. If the user equipment is connected to the base station in accordance with a legacy system non-support mode, it performs permutation for the uplink signal on the frequency axis in accordance with a second rule. Cell ID corresponding to a secondary advanced preamble (SA-preamble) received from the base station is used for permutation based on the first rule and/or the second rule.

A method for transmitting system configuration information about uplink multiplexing of a 16m mobile station (MS) and a 16e MS is disclosed. The method comprises transmitting the system configuration information every super frame comprised of a plurality of radio frames. The system configuration information comprises an uplink configuration of time division multiplexing (TDM) and frequency division multiplexing (FDM) of the 16m MS and the 16m MS for each of the plurality of radio frames.

In the present invention, an uplink synchronization signal for measuring a location of a user device is assigned to a predetermined uplink sub-frame and a predetermined sub-band and is transmitted to one or adjacent cells as well as a serving cell in a predetermined period. Since the synchronization signal for measuring the location is transmitted to a plurality of cells through the same wireless resource, other date are not transmitted to the same wireless resource and a near-far effect can be reduced in each cell.

The present invention relates to a wireless communication system. Particularly, in configuring a location estimation subframe for determining the location of a terminal in a wireless communication system, the present invention involves replacing a portion of repeating patterns of a channel estimation pilot in the location estimation subframe with a location estimation pilot. In this way, the present invention is capable of transmitting a location estimation reference signal for a location-based service to the terminal while minimizing influences on an existing wireless frame structure.

A method for allocating the resources of a remaining region other than a region carrying a SuperFrame Header (SFH) and signaling the resource allocation is disclosed. A Mobile Station (MS) receives resource allocation information about a remaining region other than a region carrying an SFH in a predetermined channel bandwidth by the SFH from a Base Station (BS) and decodes the received resource allocation information. The MS decodes control information efficiently by receiving repetition number information about a sub_secondary SFH (sub_S-SFH) or sub_secondary Broadcast CHannel (sub_S-BCH) from the BS by a Primary SFH (P-SFH) or Primary BCH (P-BCH).

A method for receiving control information and a control information signaling receiving method are disclosed. If A-MAP information is allocated and transmitted, signaling overhead is greatly reduced, resulting in improved system performance. In addition, the method increases the number of data transmission areas in inverse proportion to control signaling overhead. In accordance with the method for receiving control information signaling, a mobile station correctly recognizes a location to which A-MAP information is allocated and transmitted, resulting in increased control information decoding efficiency.

A method for transmitting signal, at a mobile station, in a wireless communication system is provided. Inter-cell interference information may be different for each frequency partition according to using a FFR scheme. Also, a parameter for controlling interference level between base stations may be different for each frequency partition. The present invention 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.
