Abstract

Métodos para sincronizar estaciones base utilizando una fuente de sincronizacion independiente o identificando una estacion base como fuente principal. Un RNC (C-RNC) o una estacion base pueden designar una estacion base o un UE para adquirir mediciones derivadas de las estaciones base, a fin de lograr la sincronizacion. Las actividades de sincronizacion pueden estar regularmente programadas o pueden Ilevarse a cabo cuando las mediciones periodicas indican que un valor de desviacion excede un umbral dado. También se divulgan estaciones base para un sistema digital inalámbrico que tienen la capacidad de realizar una sincronizacion de tiempo o de frecuencia de una pluralidad de otras estaciones base.
ARP070104452A 2002-02-05 2007-10-09 Un metodo para la sincronizacion autonoma de tiempo o frecuencia de estaciones base en un sistema de comunicacion inalambrica, y estaciones base para un sistema digital inalambrico que tienen la capacidad de realizar una sincronicacion de tiempo o de frecuencia de una pluralidad de otras estaciones AR063175A2 (es)
