For a specific UE, an uplink frequency is said to be activated if the UE is allowed to transmit on that frequency. The primary uplink frequency is always activated when configured while a secondary uplink frequency has to be activated by means of an HS-SCCH order in order to become activated. Similarly, for a specific UE, an uplink frequency is said to be deactivated if it is configured but disallowed by the NodeB to transmit on that frequency.

In addition to the serving HS-DSCH cell, a cell in the secondary downlink frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell. There can be up to two assisting secondary serving HS-DSCH cells.

In addition to the serving HS-DSCH cell, a cell in the same frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell.

A group of (one, two or three) Multiflow mode cells that have the same CPICH timing. The cells that belong to a cell group are indicated by higher layers.

For a specific UE, an uplink frequency is said to be configured if the UE has received all relevant information from higher layers in order to perform transmission on that frequency.

The non-serving HS-DSCH cell transmitting the F-DPCH that is used to estimate the F-DPCH quality for TPC command derivation, when the UE is configured with DPCCH2 in the uplink or E-DCH decoupling is configured.

DL FET refers to early termination of DL DPCH transmission upon receiving an acknowledgement message. In this context, a DL FET ACK/NACK message represents an acknowledge message sent on UL DPCCH for DL FET.

Higher layers signal this configuration parameter to indicate enhanced DCH physical layer configuration. The possible values are 0 and 1. The value 0 indicates Mode 0 configuration where DL transport channels concatenation and UL ACK/NACK signalling are not configured. The value 1 indicates Mode 1 where DL transport channel concatenation and UL ACK/NACK signalling for DL FET are configured.

An E-DCH operation mode in which the Serving HS-DSCH cell and the Serving E-DCH cell are different.

An interval of contiguous TTIs when S-CCPCHs, each on different RLs, may be soft combined.

This term refers to the downlink MIMO configuration with two transmit antennas.

This term refers to the downlink MIMO configuration with four transmit antennas.

The UE is configured in Multiflow mode when it is configured with an assisting serving HS-DSCH cell.

An HS-DSCH cell configured for a UE in Multiflow mode that has a different timing than the time reference cell. If the time reference cell is the Assisting Serving HS-DSCH cell then the non-time reference cell is the Serving HS-DSCH cell. If the time reference cell is the Serving HS-DSCH Cell, then the non-time reference cell is the Assisting Serving HS-DSCH cell.

If a single uplink frequency is configured for the UE, then it is the primary uplink frequency. In case more than one uplink frequency is configured for the UE, then the primary uplink frequency is the frequency on which the E-DCH corresponding to the serving E-DCH cell associated with the serving HS-DSCH cell is transmitted. The association between a pair of uplink and downlink frequencies is indicated by higher layers.

A secondary uplink frequency is a frequency on which an E-DCH corresponding to a serving E-DCH cell associated with a secondary serving HS-DSCH cell is transmitted. The association between a pair of uplink and downlink frequencies is indicated by higher layers.

Signalling Radio Bearers as defined in [5].

A time interval of 40ms duration aligned in time with a 40ms TTI, defined for DPCH physical layer procedures when DCH channel is configured with a single transport channel of 40ms TTI carrying SRB data only.

The (Serving or Assisting Serving, but not Secondary Serving or Assisting Secondary Serving) HS-DSCH cell that carries the HS-PDSCH acting as the time reference for the uplink HS-DPCCH when in Multiflow mode. There is one and only one Time reference cell.

When configured by higher layers for the TTI to be transmitted [9], UL DPCH follows physical channel procedures specific to this mode. UL DPCH 10ms Mode can only happen when DL_DCH_FET_Config is configured.

When configured by higher layers for the TTI to be transmitted [9], UL DPCH is transmitted continuously over a Compression Interval of 20ms, and follows the physical channel procedures specific to this mode. UL DPCH 20ms Mode can only happen when DL_DCH_FET_Config is configured.

A time interval of 20ms duration aligned in time with a 20ms TTI, defined for UL DPCH physical layer procedures when DL_DCH_FET_Config is configured by higher layers.

If the UE is configured with two uplink frequencies, the 1st secondary serving HS-DSCH cell is the secondary serving HS-DSCH cell that is associated with the secondary uplink frequency. If the UE is configured with a single uplink frequency, the 1st secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.

If the UE is configured with more than two serving HS-DSCH cells, the 2nd secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.

If the UE is configured with more than three serving HS-DSCH cells, the 3rd secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.

If the UE is configured with more than four serving HS-DSCH cells, the 4th secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.

If the UE is configured with more than five serving HS-DSCH cells, the 5th secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.

If the UE is configured with more than six serving HS-DSCH cells, the 6th secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.

If the UE is configured with eight serving HS-DSCH cells, the 7th secondary serving HS-DSCH cell is a secondary serving HS-DSCH cell whose index is indicated by higher layers.
