Organización del tráfico dedicado en el uplink y downlink




CPICH, RSCP, RSSI, Ec/No

  • CPICH (Common Pilot Channel): contiene el scrambling code de la celda
  • RSCP (Received Signal Code Power): es el nivel de potencia del CPICH (dBm)
  • RSSI (Received Signal Strenght Indication): es el nivel de potencia sobre toda la portadora de 5 MHz incluyendo todas las componentes recibidas, de la misma celda y de las adyacentes en la misma frecuencia.

  • Ec/No (Energy chip on the Noise spectral density): la energía por chip recibida dividida por la densidad de potencia de ruido.


 RSCP, RSSI, Ec/No


Ec/No = RSCP/RSSI
Ec/No (dB) = RSCP (dBm) – RSSI (dBm)
