3.1 Definitions
For the purposes of the present document, the terms and definitions given in [1] apply, together as:
Activated uplink frequency (FDD only): 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.
Adjacent Frequency: A frequency whose centre is within 5 MHz of the centre of the currently used frequency and belongs to the same frequency band as that of the currently used frequency.
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.
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.
Blind HARQ retransmissions for HSDPA (FDD only): A HARQ operation where a UE in CELL_DCH state supports reception of MAC-hs/ehs PDU within 5 sub-frames from the reception of the previous MAC-hs/ehs PDU intended for the same HARQ process.
Common E-DCH resource: In FDD, common E-DCH resources are under direct control of the Node B and are shared by UEs in CELL_FACH state and IDLE mode. In 1.28 Mcps TDD, common E-DCH resources used by UEs in CELL_FACH and IDLE mode are under direct control of Node B and are shared by UEs in the CELL_DCH state.
Common E-RGCH RL: Cell which is not the serving E-DCH radio link and from which the UE can receive one Relative Grant in CELL_FACH state. The UE can have zero, one or up to 3 Common E-RGCH RL(s).
Configured Uplink Frequency (FDD only): For a specific UE, an uplink frequency is said to be configured if the UE has received all relevant information from RRC in order to perform transmission on that frequency.
CSG member cell: a cell broadcasting the identity of the selected PLMN, registered PLMN or equivalent PLMN and for which the Permitted CSG list of the UE includes an entry comprising the cell’s CSG ID and the respective PLMN identity.
Current Frequency (FDD only): The frequency that is currently used by the UE. In case of dual cell or dual band configured, the serving HS-DSCH cell frequency is treated as current frequency.
Data Description Indicator (DDI): MAC-e header field used to identify the logical channel, MAC-d flow and the size of the MAC-d PDUs concatenated into a MAC-es PDU.
Designated non-serving HS-DSCH cell: The non-serving HS-DSCH cell from which the UE estimates the F-DPCH quality for TPC derivation, when the UE is configured with DPCCH2 in the uplink or the Serving E-DCH cell decoupling is configured. This TPC is transmitted on UL DPCCH.
E-DCH active set (FDD only): The set of cells on the primary uplink frequency which carry the E-DCH for one UE. Only radio links for which an E-HICH configuration is stored are considered part of the E-DCH active set.
Enhanced Uplink in CELL_FACH state and Idle mode: In FDD, combines the REL99 random access power ramping phase with E-DCH transmission. The procedure can be started in idle mode and RRC Connected mode, but not in CELL_DCH state. In 1.28 Mcps TDD, the REL7 enhanced random access procedure for E-DCH in CELL_DCH is used in idle mode and CELL_FACH state.
HARQ profile: One HARQ profile consists of a power offset attribute and maximum number of transmissions.
Implicit Grant handling: A scheduling scheme where a UE’s Scheduling Grant on the Secondary Serving E-DCH cell may be revoked by means of an Absolute Grant addressed to another UE.
MBMS activated services: the MBMS multicast services the UE has joined as well as the broadcast services the UE is interested in.
MCCH acquisition: the procedure for acquiring all MCCH information relevant for the UE ie. includes reception of the RB information for the UE’s MBMS activated services.
MBMS controlling cell: the cell from which the UE receives MCCH.
MBMS notification: a notification provided by UTRAN indicating a change in the provision of one or more MBMS services.
MBMS Selected Services: a subset of the MBMS activated services of the Broadcast type for which the UE applies RRC procedures to inform UTRAN that the service has been selected (by upper layers).
MBMS transmission: a possibly repeated session of an MBMS service. An MBMS transmission is uniquely identified by the combination of the MBMS service identity and the MBMS session identity.
MBSFN cluster: Set of cells operating in MBSFN mode providing only MBMS service in PtM mode and seen as one cell by a UE.
MBSFN mode: Transmission mode where a set of synchronized cells transmit exactly the same data for provision of MBMS service.
Multiflow (FDD only): A mode of operation with two simultaneous HS-DSCH transport channels per carrier frequency, where the HS-DSCH transport channels may belong to the same or different Node Bs.
NodeB triggered HS-DPCCH transmission: Transmission on a common E-DCH resource to provide HS-DPCCH feedback in CELL_FACH state, which is triggered by the reception of an HS-SCCH order as defined in [16].
Primary Absolute Grant (FDD only): Absolute Grant received with the primary E-RNTI.
Primary uplink frequency (FDD only): If a single uplink frequency is configured for the UE, then it is the primary uplink frequency. In case more than one uplink frequencies are configured for the UE, then the primary uplink frequency is the frequency on which 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.
Radio Links without DPCH/F-DPCH operation (FDD only): An operation mode in which UE supports to not receive both DPCH and F-DPCH downlink channels from the indicated Non-serving E-DCH cell(s).
Secondary Absolute Grant (FDD only): Absolute Grant received with the secondary E-RNTI.
Secondary E-DCH Active Set (FDD only): The set of cells on the secondary uplink frequency where E-DCH is carried for one UE. Only radio links for which an E-HICH configuration is stored are considered part of the secondary E-DCH active set. The secondary E-DCH active set and the active set on the secondary uplink frequency are always the same set of cells.
Secondary Serving E-DCH cell (FDD only): Cell from which the UE receives Absolute Grants from the Node-B scheduler on the downlink frequency associated with secondary uplink frequency. A UE has one Secondary Serving E-DCH cell on the secondary uplink frequency.
Secondary Serving E-DCH RLS or Secondary Serving RLS (FDD only): In Dual Cell E-DCH operation, the set of cells which contains at least the Secondary Serving E-DCH cell and from which the UE can receive and combine one Relative Grant. A UE can have zero or one Secondary Serving E-DCH RLS.
Secondary serving HS-DSCH cell(s): In addition to the serving HS-DSCH cell, the set of cells where the UE is configured to simultaneously monitor an HS-SCCH set and receive the HS-DSCH if it is scheduled in that cell. There can be up to 7 secondary serving HS-DSCH cells. If the UE is configured with two uplink frequencies, the first secondary serving HS-DSCH cell is the secondary serving HS-DSCH cell that is associated with the secondary uplink frequency.
Secondary Non-serving E-DCH RL or Secondary Non-serving RL (FDD only): In Dual Cell E-DCH operation, the cell which belongs to the Secondary E-DCH active set but does not belong to the Secondary Serving E-DCH RLS and from which the UE in CELL_DCH can receive one Relative Grant. The UE can have zero, one or several Secondary Non-serving E-DCH RL(s).
Secondary uplink frequency (FDD only): 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.
Serving E-DCH cell: Cell from which the UE receives Absolute Grants from the Node-B scheduler. In TDD, a UE has one Serving E-DCH cell. In FDD, a UE has one Serving E-DCH cell on the primary uplink frequency.
Serving E-DCH cell decoupling (FDD only): An E-DCH operation mode in which the Serving HS-DSCH cell and the Serving E-DCH cell are different.
Serving E-DCH RLS or Serving RLS (FDD only): Set of cells which contains at least the Serving E-DCH cell and from which the UE can receive and combine one Relative Grant. In TDD, the UE has only one Serving E-DCH RLS. In FDD, a UE has one Serving E-DCH cell on the primary uplink frequency.
Non-serving E-DCH RL or Non-serving RL (FDD only): Cell which belongs to the E-DCH active set but does not belong to the Serving E-DCH RLS and from which the UE in CELL_DCH can receive one Relative Grant. In TDD, the UE can have zero, one or several Non-serving E-DCH RL(s). In FDD, the UE can have zero, one or several Non-serving E-DCH RL(s) on the primary uplink frequency.
SR-VCC: Single Radio Voice Call Continuity, Voice call or Voice and Video call continuity between IMS over PS access and CS access for calls that are anchored in IMS when the UE is capable of transmitting/receiving on only one of those access networks at a given time. Single Radio Voice Call Continuity between CS access and IMS over PS access is referred to as Reverse SRVCC (rSR-VCC).
Target Cell Pre-Configuration (FDD only): HS-DSCH Cell configuration provided to UE in Active Set Update for which HS-DSCH serving Cell Change may be initiated by HS-SCCH order sent from target cell.
Target cell HS-SCCH order: A HS-DSCH serving cell change command signaled to an UE by using HS-SCCH order in the target cell:
– for which a measurement report was trigged by an Event 1d intra frequency event; or
– for which a measurement report was trigged by an Event 1c intra frequency event on the primary frequency, which indicates the current serving HS-DSCH cell as the only active CPICH triggering this event 1c report, and the target cell is the best cell in the current active set reported in this Event 1c measurement report. If more than one cell in the active set share the same quality, the target cell will be the first one listed in the in "Intra-frequency measured results list" in the Event 1c measurement report.
Primary E-DCH carrier (1.28Mcps TDD only): If a single E-DCH carrier is configured for the UE, then it is the primary E-DCH carrier. In case more than one E-DCH carriers are configured for the UE, then the primary E-DCH carrier is the carrier on which the E-RUCCH will be transmitted.
Additional E-DCH carrier (1.28Mcps TDD only): An additional E-DCH carrier is an E-DCH carrier other than the primary E-DCH carrier . The UE can have zero, one or several additional E-DCH carrier(s).
