摘要： Disclosed is a method and apparatus for efficiently controlling buffers which support a Hybrid Automatic Repeat Request (HARQ) in a wireless communication system. Buffer regions for the HARQ scheme are not fixedly allocated according to channel identification information, but are allocated from the viewpoint of one overall memory through aggregation support. That is, an HARQ buffer is dynamically controlled. Therefore, there are the effects reducing the size of the entire chip, as well as reducing power consumption of the entire system according to the reduction of the chip size.

摘要： A method and apparatus for processing time windowing to transmit a signal in a Broadband Wireless Access (BWA) communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). A signal of a first interval included in a previous symbol prior to a current symbol is stored as a signal of a previous symbol interval. The current symbol includes a guard interval and an effective symbol interval subsequent to the guard interval. The current symbol is windowed by overlapping the stored signal of the first interval with a signal of a second interval included in the current symbol subsequent to the previous symbol. A windowed signal is transmitted.
