    摘要： Apparatus and method of providing transparent relay service to a Mobile Station (MS) in a multihop relay Broadband Wireless Access (BWA) communication system. The communication method includes checking, at least one relay station (RS), a sounding channel allocated to an MS by analyzing a message broadcast from a Base Station (BS); measuring, at the BS, an BS-MS signaling level using a sounding signal of the MS, the sounding signal received in the sounding channel; measuring, at the at least one RS, an RS-MS signaling level using a sounding signal of the MS, the sounding signal received in the sounding channel; reporting, at the at least one RS, the RS-MS signaling level measurement value to the BS; and selecting, at the BS, an RS suitable for the MS using the BS-MS signaling level measurement value and at least one RS-MS signaling level measurement value reported from the at least one RS. Accordingly, the BS can select a suitable RS for the MS by taking into account the RS-MS channel status.

    摘要： Disclosed is a method for transmitting a reference signal for identification of each cell in a communication system including a plurality of cells each of which is identified by a cell identifier. The method includes receiving a cell identifier, and generating a block code corresponding to the cell identifier using a predetermined block code generator matrix, and generating a first part sequence using the block code; selecting a second part sequence in accordance with the cell identifier; generating a reference signal of a frequency domain using the first part sequence and the second part sequence; converting the reference signal of the frequency domain to a reference signal of a time domain through an Inverse Fast Fourier Transform operation and transmitting the reference signal of the time domain in a predetermined reference signal transmission interval.

    摘要： A method for controlling a sleep mode operation by a mobile station (MS) in a communication system. In the sleep mode operation control method, after entering a sleep mode, the MS transitions to an awake state in a listening interval. When there is data to transmit or receive to/from a base station (BS) in the awake state, the MS causes a neutral interval following the listening interval to transition to the awake state, and transmits or receives the data. The neutral interval is an interval where transition to the awake state and sleep state is available according to the data transmission/reception of the MS operating in the sleep mode.
