6.2.2.5
Fractional Dedicated Physical Channel (F-DPCH)
The F-DPCH is a special case of a downlink DPCCH carrying TPC information (see
3GPP TS 25.211). It is required to transport TPC information when no normal DPCCH
is available, e.g. for HSDPA. Each F-DPCH slot is subdivided into 10 256-chip periods.
The second 256-chip period is used to transmit 2 TPC bits. During the remainder of the
slot, the TX power is switched off.
Fig. 6-5: Structure of F-DPCH
The time offset of the F-DPCH relative to the P-CCPCH is UE-specific, which allows to
superimpose several F-DPCHs in order to allocate TPC information to up to 10 differ-
