Do you mean link budget? It also depends on which system you want to know.

how did you calculate this?

DL_PL(i) = Pcpich(i) – RSCP(i)；
UL_PL(i) = Pdpcch – Rdpcch(i) = Pdpcch – (ULSIR(i) – PG_SF256 – UL_Intf(i))

these equations are not equivalent
the first is correct in terms of measuring DL path loss, which corrsponds to the UL path loss FOR THE SAME REFERENCE POINTS (i.e. outside of the Node-b antenna, inside of the UE RF chain) adjusted for the difference between uplink/downlink frequency bands
