Explain Ec/Io and RSCP; on what channel are they measured on?

Question:  Explain Ec/Io and RSCP; on what channel are they measured on?

 

Answer:  Ec/Io = energy of carrier over all noise. RSCP = Receive Signal Code Power. In FDD mode (what we normally deal with) they are measured on the CPICH (pilot). Bonus if they know that Io is the sum of all interference: thermal/bg noise + interferers + own cell and is wideband. Bonus if they understand that RSCP is actually measured AFTER despreading (i.e. narrowband)
