A Framework for Uplink Power Control in Cellular Radio Systems
In cellular wireless communication systems, transmitted power is regulated to provide each user an acceptable connection by limiting the interference caused by other users. Several models have been considered including: (1) xed base station assignment where the assignment of users to base stations is xed, (2) minimum power assignment where a user is iteratively assigned to the base station at w...
متن کاملTransmitter Power Control for Co-channel Interference Management in Cellular Radio Systems
Transmitter power control is a necessity to combat "near-far" problems in radio systems using receivers with limited "dynamic range" (such as conventional DSCDMA systems). Transmitter power control, however, can also be used to control cochannel interference, i.e. interference from other users using the same channel (code or time slot). For this purpose, it has been shown that the optimum trans...
متن کاملStochastic power control for cellular radio systems
For wireless communication systems, iterative power control algorithms have been proposed to minimize transmitter powers while maintaining reliable communication between mobiles and base stations. To derive deterministic convergence results, these algorithms require perfect measurements of one or more of the following parameters: 1) the mobile’s signalto-interference ratio (SIR) at the receiver...
متن کاملPower Control in Cellular Radio Systems
The primary goal of cellular radio systems is to provide communications services to a large number of mobile users. Due to the dramatic increase of this market, the available resources have to be utilized efficiently. Closedloop power control is considered as an important component in these resource management algorithms. Here, relevant aspects on power control are discussed, using an automatic...
متن کاملJoint Power Control in Cellular Radio Systems
— Transmitter power control has proven to be an efficient method to control interference and to improve spectrum utilization in cellular and personal communication systems. Previous results have shown that a significantly higher capacity may be reached, even if the system is subject to (practical) power constraints. Since in most cellular systems a duplex link is required, adequate transmission...
