Power control (PC) techniques have been studied for years with the aim of reducing interference and allowing efficient battery energy management. Among PC algorithms, those based on the signal level (not on cochannel interference) show good characteristics in terms of network stability and provide optimum downlink performance when a half-compensation scheme is used instead of a full-compensation algorithm. This work is concerned with partial (including the full and half cases) compensation

A time division multiple access (TDMA)-based cellular system is considered. The effect of a slow PC, i.e., following only slow channel fluctuations, on the average transmitted power of mobile terminals is evaluated through a completely analytical model; both ideal and nonideal PC are considered. Starting from suitable requirements on radio coverage, we show that a half-compensation PC scheme is often a good choice for extending terminal battery life (thus, also reducing health risks).
