摘要： Apparatuses, methods, and systems of measuring received power are described, including apparatuses, methods, and systems which can measure received power, even when the subcarrier offset of the measurement bandwidth is different from the subcarrier bandwidth of the cell bandwidth. In one method, the first received power of a plurality of Resource Blocks (RBs) received from a second Base Station (BS) are measured based on first channel state information received from a first BS. Based on the determination whether a value of an index included in the first channel state information is larger than a predetermined value, at least one of second received power, third received power, and fourth received power of the plurality of RBs is measured by using second channel state information including an alternative index determined based on the first channel state information based on a result of the determination.

摘要： Provided is a channel estimation apparatus and method. In the channel estimation apparatus, a channel estimator performs channel estimation onto a received symbol and output a channel estimation result. The channel estimation result is stored in an estimation buffer along with a channel estimation result compensated in a preamble phase compensator. The preamble phase compensator receives a channel estimation result for pilot subcarriers of a data symbol and a preamble channel estimation result from the estimation buffer, acquires a phase rotation value between them, and compensates the preamble channel estimation result with the phase rotation value. When FCH and DL-MAP are demodulated, pilot subcarriers in the Nth PUSC symbol have been used to estimate the channel of the Nth PUSC symbol.

摘要： An apparatus and method for improving a HARQ combining gain in a broadband wireless communication system are provided. The apparatus includes a seed information generator and a subcarrier allocator. The seed information generator randomly generates a seed value for changing a channel of a subcarrier and an interference pattern in a frame unit when a HARQ combining gain is not generated because an interference pattern is the same during a retransmission period. The subcarrier allocator allocates a subcarrier using the generated seed value.

摘要： An apparatus and method are provided for estimating a Carrier-to-Interference-and-Noise Ratio (CINR) in a communication system based on Orthogonal Frequency Division Multiplexing (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA). In the communication system, all base stations boost a power level for a preamble or pilot by B dB. Accordingly, a received signal power level and a received interference level are boosted by B dB, but a noise level is not boosted. Transmission power for a preamble or pilot interval is boosted as compared with that for the data interval. After an interference and noise level is estimated from a preamble or pilot, the interference and noise level estimate of the preamble or pilot is corrected by taking into account a boosting level of the preamble or pilot.
