A method of determining a cell identity in a wireless communication system is disclosed. The present invention includes the steps of obtaining a segment ID and a sequence index from an SA-preamble (secondary advanced preamble) sequence received from a base station and determining the cell identity using the segment ID and the sequence index. In this case, the cell identity corresponds to one SA-preamble sequence and a cell identity adjacent to the cell identity corresponds to an SA-preamble sequence having a complex conjugate relation of the one SA-preamble sequence.

The present invention relates to a wireless communication system. In particular, for the transmission of a locating zone configured across one or more superframes for transmitting a locating synchronizing signal for determining the location of a terminal in a wireless communication system, the wireless communication system of the present invention transmits, to a terminal, a superframe header including information indicating whether or not to transmit the locating zone. Thus, the terminal can discern a terminal belonging to the location zone form among superframes received by the terminal.

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 of signaling system configuration information in a wireless mobile cellular communication system is disclosed. The method comprises transmitting the system configuration information at every predetermined period. In this case, each downlink subframe is divided into a plurality of frequency partitions, and subcarriers from at least two of the plurality of frequency partitions are allocated to a first mobile station using distributed resource allocation.

A method for configuring subchannels for an uplink data transmission at a base station in a wireless communication system is disclosed herein. More specifically, the method includes the steps of dividing an uplink transmission resource to PUSC (Partial Usage of SubChannel) tiles of 4 subcarriers×3 symbols, configuring subchannels to 6 PUSC tiles based on a predetermined rule; allocating a predetermined number of contiguous subchannels among the configured subchannels as subchannels for a legacy system, and allocating the remaining subchannels as subchannels for the wireless communication system, wherein a subchannel rotation per slot consisting of 3 symbols is applied to the subchannels for the legacy system, and wherein the subchannel rotation per slot is based on a number of subchannels for the legacy system.

A wireless communication system is disclosed. The wireless communication system transmits a location measure signal for determining a location of a user equipment to the user equipment by allocating the location measure signal to at least one of symbols to which a synchronization signal is transmitted conventionally. In this case, a location related parameter of the user equipment can be measured with higher accuracy.

A method for configurating a basic signal allocation unit and a method of transmitting signals using the configurated basic signal allocation unit are disclosed. In particular, a basic frequency domain signal allocation unit is configurated by considering at least one selected from the group consisting of a signaling overhead, a size of a coherent bandwidth and a number of divisors among specific numbers and an OFDM symbol number corresponding to a multiple of a subframe unit, each of the specific numbers multiplied to a predetermined subcarrier spacing to enable a result value of the multiplication to have a difference smaller than a prescribed threshold from a divisor of a system bandwidth. And, a time domain unit is configurated by 1-subframe unit. Accordingly, signaling overhead can be efficiently reduced.
