Abstract: An apparatus and a method for processing bandwidth request in a multi-hop relay broadband wireless access communication system are provided to enable a relay station to report the number of terminals which transmit bandwidth request ranging code to a base station. A relay station extracts receiving signals from a bandwidth request ranging region(301). The relay station performs code demodulation by correlating the ranging code with the extracted data(303). The relay station judges whether the bandwidth request ranging code is received from the code demodulation result(305). The relay station decides the number of terminals which transmit the bandwidth request ranging code(307). The relay station reports the number of the terminals to the base station through a previously allotted feedback channel(309). The relay station verifies whether a resource allotment message responding to the bandwidth request ranging code is received from the base station(311). The base station writes information concerned with the ranging code within the received resource allotment message(313). The relay station transmits the resource allotment message to the terminal(315).

Abstract: A method and an apparatus for frame synchronization in a broadband wireless access communication system are provided to improve a frame synchronization acquiring property of the communication system by discriminating a pattern with a maximum correlation value. An apparatus for a frame synchronization in a broadband wireless access communication system includes plural preamble detectors(400-0,400-1,...,400-I), an adder(402), and a synchronization determining unit(404). The preamble detectors perform a phase compensation process on received samples corresponding to received patterns, calculate correlation values of the patterns by using the phase-compensated samples, and output the correlation values. The adder accumulates the correlation values from the preamble detectors. The synchronization determining unit compares the added results from the adder with one another, selects a maximum value, and determines a time index corresponding to the maximum value as the frame synchronization value.

Abstract: An apparatus and a method for transmitting/receiving signals in a wireless communication system are provided to enable an MS(Mobile Station) to transmit/receive signals with more than two BSs(Base Stations) by making a serving BS and BSs having a similar signal strength to the serving BS transmit respectively different signals to the MS. An MS executes communication with the first BS, or a serving BS, and receives signals from the first BS. At this moment, the MS periodically measures the strength of signals received from neighbor BSs and confirms whether a BS having a similar signal strength to the first BS exists(501). In case it is confirmed that the second BS, a BS having a similar signal strength to the first BS, exists, the MS transmits a macro multiplexing request message to the first BS(503). In response to the macro multiplexing request message, the first BS transmits a macro multiplexing execution request message to the second BS in order to confirm whether the second BS can transmit signals to the MS(505). Receiving the macro multiplexing execution request message, the second BS confirms its own resource information. If it is judged that a resource to be allocated to the MS exists, the second BS allocates the resource to the MS. Then, the second BS transmits a macro multiplexing enable confirmation message to inform the first BS that the second BS can transmit signals to the MS(507). In response to the macro multiplexing enable confirmation message, the first BS transmits a macro multiplexing execution confirmation message to the second BS(509). Then the first BS transmits a macro multiplexing permission message to the MS(511).
