Abstract

Método y disposicion de comunicaciones para mantener la sincronizacion en una red de comunicaciones con energía limitada, tal como un sistema deradiocomunicaciones movil TDMA con base en satélite. De acuerdo con los ejemplos, el satélite transmite ráfagas abreviadas que contienen solamenteinformacion de sincronizacion durante entervalos cuando la unidad movil receptora no requiere ninguna otra informacion de control, reduciendo elconsumo de energía durante esos intervalos.
