3.3 Definitions
Assisting secondary serving HS-DSCH Cell: 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.
Assisting serving HS-DSCH Cell: 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.
DL FET: 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.
DL_DCH_FET_Config: 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 DL FET ACK/NACK signalling on UL are not configured. The value 1 indicates Mode 1 where DL transport channel concatenation and DL FET ACK/NACK signalling on UL are configured.
HS-DSCH cell set: A set of cells that can be configured together as the serving and secondary serving HS-DSCH cells for a UE. This term is applicable also to non-serving cells in an active set.
MIMO mode: This term refers to the downlink MIMO configuration with two transmit antennas
MIMO mode with four transmit antennas: This term refers to the downlink MIMO configuration with four transmit antennas
Multiflow mode: The UE is configured in Multiflow mode when it is configured with an assisting serving HS-DSCH cell.
Non-time reference 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.
Time reference cell: The (Serving or Assisting Serving, but not Secondary Serving or Assisting Secondary Serving) HS-DSCH cell acting as the time reference for the uplink HS-DPCCH when the UE is configured in Multiflow mode. There is only one Time reference cell.
UL DPCH 10ms Mode: When configured by higher layers for the TTI to be transmitted [18], UL DPCH follows physical channel procedures specific to this mode. UL DPCH 10ms Mode can only happen when DL_DCH_FET_Config is configured.
UL 20ms Compression Interval (CI): A time interval of 20ms duration aligned to a 20ms TTI defined for UL DPCH physical layer procedures when DL_DCH_FET_Config is configured by higher layers.
