What is RSCP & Ec/Io

What is Ec/Io and RSCP? And on what channel are they measured on? Ec/Io & RSCP are terms related to WCDMA. Ec/Io : It is the ratio of Received power of the carrier to the all over Noise. It is used to measure quality of Pilot Channel. RSCP : Received Signal Code Power. It is measured after despreading of the signal (Narrowband). It is a some of RSSI(Received signal strength) and Ec/No in dbm. RSCP (dbm) = RSSI(dbm)+Ec/No(dbm) Difference between RSSI & RSCP: RSSI - "Receive Signal Strength Indicator", is a circuit to measure the strength of an incoming signal. RSCP :The Received Signal Code Power is the received power on one DPCH, PRACH or PUSCH code after de-spreading, defined on the pilot symbols
