There is only one E-DCH per CCTrCh of E-DCH type.

For both 2 ms and 10 ms TTI, the information carried on the E-DPCCH consists of 10 bits in total: the E-TFCI (7 bits), the RSN (2 bits) and the ‘happy’ bit (see in subclause 9.3.1.2).

The E-DPCCH is sent with a power offset relative to the DPCCH. The power offset is signalled by RRC.

If E-DCH is used in CELL_FACH state and Idle mode, then no parallel DCH transmission is supported.

The network is able to configure with the system information whether the UE transmits HS-DPCCH after collision resolution in the CELL_FACH state when it has E-DCH resources allocated. If the UE is transmitting CCCH HS-DPCCH is not transmitted.
