Uplink DPDCH/DPCCH Frame Structure
There are two types of uplink dedicated physical channels, the uplink Dedicated Physical
Data Channel (uplink DPDCH) and the uplink Dedicated Physical Control Channel
(uplink DPCCH). The DPDCH and the DPCCH are I/Q multiplexed within each radio
frame.
The uplink DPCCH is used to carry control information generated at Layer 1. The Layer 1
control information consists of known pilot bits (Pilot) to support channel estimation for
coherent detection, transmit power control (TPC) commands, feedback information (FBI),
and an optional transport format combination indicator (TFCI) as shown in Figure 4-4.
The TFCI informs the receiver regarding the instantaneous transport format combination
of the transport channels mapped to the simultaneously transmitted uplink DPDCH radio
frame.
