    摘要: An apparatus and method for estimating a cell load in a wireless communication system are provided. The apparatus includes a ranging response counter, a load estimator, an FA handover determiner, a data rate determiner, and a handover determiner. The ranging response counter counts the number of ranging response messages that are received during one period of periodic ranging. The load estimator estimates a cell load on the basis of the number of the ranging response messages. The FA handover determiner determines an FA handover on the basis of the cell load from the load estimator. The data rate determiner controls a data rate of a service on the basis of the cell load from the load estimator and requests the controlled data rate to the system. The handover determiner controls handover parameters on the basis of the cell load from the load estimator.

    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: In a Broadband Wireless Access (BWA) communication system having at least two FAs, a base station (BS) requests a subscriber station (SS) to change its FA from the first FA to the second FA, upon detecting a need to change an FA of the SS from the first FA to the second FA while communicating with the SS. The SS informs the BS that it will change its FA from the first FA to the second FA in response to the FA change request, and then changes its FA from the first FA to the second FA. After changing the FA, the SS communicates with the BS through the second FA.
