Abstract

La presente invención se refiere a una estación base para detectar una transmisión por el Canal Físico de Acceso Aleatorio (PRACH) de un dispositivo de Equipo de Usuario (UE) que comprende un dispositivo de radio y al menos un dispositivo adicional. El dispositivo de radio comprende una variedad de receptores de banda estrecha respectivamente acoplados en una variedad de elementos de antena de un arreglo de antenas. Cada receptor de banda estrecha está configurado para recibir una señal de un elemento de antena respectivo y procesar la señal para proporcionar símbolos recibidos para una PRACH recibida a través del elemento de antena respectivo. El dispositivo de radio también comprende circuitos de acumulación configurados para, para cada elemento de antena, acumular un subconjunto de los símbolos recibidos para la PRACH recibida a través del elemento de antena para producir un primer símbolo promediado para la PRACH recibida a través del elemento de antena. Al menos un dispositivo adicional se configura para recibir, desde el dispositivo de radio, los primeros símbolos promediados y procesar los primeros símbolos promediados para que la PRACH realice la detección de PRACH para uno o más haces de recepción.
