摘要： An Apparatus and a method for interference cancellation in a wireless communication system are provided. When a resource of an Interference Cancellation (IC) zone is allocated to a terminal traveling in a service coverage, resource allocation information relating to an IC zone of neighbor cells is gathered. Resource allocation information is generated relating to the resource allocated to the terminal comprising resource allocation information of the IC zone of the neighbor cells. The resource allocation information relating to the resource allocated to the terminal is transmitted to the terminal. Accordingly, when the interference is present, the interference cancellation is carried out to reduce the load on the terminal and enhance the reception performance.

摘要： An apparatus and method for renewal-based resource allocation in a Broadband Wireless Access (BWA) system are provided. A Base Station (BS) allocates resources to a Mobile Station (MS) by resource allocation information. It is determined whether the MS requires continuous resource allocation or whether the MS does not have transmission data temporarily, when a resource allocation duration for downlink resources allocated to the MS has expired. One of resource allocation termination, resource allocation renewal, and temporary resource lending to another MS is performed according to the determination. Information for updating the resource allocation information is transmitted to the MS.

摘要： A transmission apparatus and method for a communication system based on Orthogonal Frequency Division Multiplexing-Code Division Multiplexing (OFDM-CDM). A frequency spreader multiplies symbols to be transmitted by a frequency spreading factor and outputs frequency spread symbols whose number corresponds to the frequency spreading factor. Buffers whose number corresponds to the frequency spreading factor temporarily store the frequency spread symbols in a unit of a predefined number of symbols. A time spreader multiplies parallel frequency spread symbols from the buffers by a time spreading factor and outputs frequency-time spread symbols. An Inverse Fast Fourier Transform (IFFT) processor performs IFFT on the frequency-time spread symbols, and outputs an OFDM symbol. A Guard Interval (GI) inserter inserts a GI into a signal output from the IFFT processor and transmits the signal. The system can obtain complete diversity gain and residual gain due to the effect of a time-varying channel in any channel environment.
