Patent ID: 6888810

Claim:
A wireless communication device for use in a DS/CDMA mobile communication system, the wireless communication device being operable in response to a sequence of reception signals divisible into a plurality of frames each of which has a frame rate and which is further divided into a plurality of slots, the reception signal sequence being processed with a processing time and a delay time in the wireless communication device, comprising: processing means for statistically processing preceding frame rates in previously received ones of the frames to produce a result of statistical processing, the previously received frames being determined on the basis of a time difference between the processing time and delay time; predicting means for predicting a later one of the frame rates in a next one of the frames on the basis of the result of statistical processing to produce a predicted frame rate of the later one of the frame, the next frame being determined with reference to the time difference between the processing time and the delay time; and executing means for executing a predetermined operation within candidate ones of the slots determined for the predicted frame rate.
