Abstract :
The problem of a number of mobile users attempting to send data packets over a commonly shared slotted channel to a central base station is studied. A scheme for controlling the transmit power of the mobiles is proposed and shown to yield better throughputs than a conventional transmit power scheme (in which all mobiles transmit with constant power) for both nonfading and fading channels. In any given time slot, mobiles that are closer to the base station are allowed to transmit at a higher power level in an attempt to improve capture probability
