An apparatus and method for controlling decoding in a wireless communication system are provided. Data is received in a slot associated with a packet to be received. A threshold is determined according to format information of the packet. It is determined whether to decode the received data by comparing the threshold with the number of slots received in relation to the packet. The received data is stored without decoding, if the number of the received slots is less than or equal to the threshold. The received data is decoded to recover the packet, if the number of the received slots is greater than the threshold.

Method and apparatus for selective decoding in a wireless communication system

An apparatus and method for estimating UpLink (UL) transmission timing in a Mobile Station (MS) of a wireless communication system are provided. The method includes tracking DL timing by using a DL preamble signal received for each frame; estimating a time offset between a previous frame and a current frame by using the DL timing tracked for each frame; and estimating the UL transmission timing by using the estimated time offset.

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.

Disclosed is an apparatus and a method for actively adjusting the quantization interval of signals inputted to a decoder in a digital communication system. The apparatus includes a quantization level generator for measuring a dynamic range of received packet data and calculating a corresponding scale factor, and an input signal converter for scaling a received data signal according to the scale factor so as to output a quantized signal.

Apparatus and method for quantization in digital communication system

An apparatus and method for supporting an Assisted Global Positioning System (AGPS) during emergency service in a communication system are provided. The system includes a client, an integration location server, and a dual mode Mobile Station (MS). The client requests MS location information for emergency service. The integration location server receives MS access information and sends a location information request. The dual mode MS receives the location request, activates a second communication modem, and performs an AGPS operation with the integration location server.
