What is F-DPCH (Fractional DPCH)?

Fractional DPCH is a unique sort of DPCH channel which can communicate power control signals. Fractional DPCH was included in Rel-6 to advance the utilization of downlink channelization codes. F-DPCH is utilized with the goal that various UE’s can share a single DL channelisation code. By utilizing F-DPCH the cell capacity has been improved and simultaneously for the same number of users, the interference has gone down significantly.
