What is FDPCH (Fractional DPCH)?

F-DPCH (Fractional Dedicated Physical CHannel) is an uncommon kind of DPCH channel. It can communicate only with power control signals. F-DPCH was first characterized in 3GPP rel6 and afterward further upgraded in rel7 to overcome some delicate handover impediments. SF 256 is utilized for A-DPCH thus every code being utilized by a client is truly exhausting the codes accessible for other UE’s. To defeat this F-DPCH is utilized so numerous UE’s can share a solitary DL channelisation code.
