Gprs is packet - switched which means that multiple users share the same transmission channel, only transmitting when they have data to send
整合封包無線電服務是小包-轉變了當他們有數據送的時候，多個使用者分享相同的傳輸頻道，唯一的傳輸哪一個方法。 -
In this scheme, power control is primary to the rate control. when the fading channel changes slowly, the transmit data rate will be kept on an appropriate level, and only the power control works to keep up with the channel fading and balance the sir. but when the channel quality is poor, the data rate will be switched down without sacrificing the ber ; otherwise, high data rate was selected
我們提出的方案根據反饋的sir動態改變數據的速率和功率，其中功率控制優先於速率控制，當通道變化緩慢時，數據率保持在一個相對穩定的值上，調節發射功率來維持sir平衡；當功率調節無法彌補通道的衰落時，則通過調節速率來維持sir的平衡。 -
