Abstract :
The progressive introduction of packet switched (PSW) services in GSM networks sharing the same physical resources involves interference control techniques that preserve the quality of speech communications. This article presents a downlink power control (DLPC) algorithm for (E)GPRS that considerably reduces the interference introduced by PSW in mixed environments, notably increasing the system capacity around 32% for EGPRS, 50% for GPRS (CS1 and CS2) and 33% for GPRS (from CS1 to CS4).
