27、he present document, the terms and definitions given in 3GPP TR 21.905 2 and the following apply: Active Process: HARQ process for which Scheduling Grants are applicable, i.e. scheduled data can be sent. Data Description Indicator (DDI): MAC-e header field used to identify the logical channel, MAC-d
28、 flow and the size of the MAC-d PDUs concatenated into a MAC-es PDU. E-DCH: Enhanced DCH, a new dedicated transport channel type or enhancements to an existing dedicated transport channel type. E-DCH active set: The set of cells which carry the E-DCH for one UE. E-DCH MAC-d flow: MAC-es PDUs, carryi
29、ng MAC-d data sharing the same traffic characteristics, and that can be multiplexed with MAC-es PDUs of same or other MAC-d flows on MAC-e. HARQ profile: One HARQ profile consists of a power offset attribute and maximum number of transmissions. Inactive Process: HARQ process for which Scheduling Gra
30、nts are not applicable, i.e. scheduled data cannot be sent. ETSI ETSI TS 125 309 V6.6.0 (2006-03) 7 3GPP TS 25.309 version 6.6.0 Release 6 INACTIVE: Absolute Grant value that can be sent by the serving cells scheduler on the E-AGCH to deactivate a process or to switch the UE to its secondary E-RNTI.
31、 Power offset attribute: Represents the power offset between E-DPDCH(s) and reference E-DPDCH power level for a given E-TFC. This power offset attribute is set to achieve the required QoS in this MAC-d flow when carried alone in a MAC-e PDU and subsequently in the corresponding CCTrCh of E-DCH type.
32、 Details on the mapping on Beta factors can be found in 3. The reference E-DPDCH power offset is signaled to the UE for one (or several) reference E-TFC(s) (see details in subclause 11.1). Primary Absolute Grant: Absolute Grant received with the primary E-RNTI. Secondary Absolute Grant: Absolute Gra
33、nt received with the secondary E-RNTI. Serving E-DCH cell: Cell from which the UE receives Absolute Grants from the Node-B scheduler. A UE has one Serving E-DCH cell. Serving E-DCH RLS or Serving RLS: Set of cells which contains at least the Serving E-DCH cell and from which the UE can receive and c
34、ombine one Relative Grant. The UE has only one Serving E-DCH RLS. Non-serving E-DCH RL or Non-serving RL: Cell which belongs to the E-DCH active set but does not belong to the Serving E-DCH RLS and from which the UE can receive one Relative Grant. The UE can have zero, one or several Non-serving E-D
35、CH RL(s). 3.2 Abbreviations For the purposes of the present document, the abbreviations given in 3GPP TR 21.905 2 and the following apply: AG Absolute Grant E-AGCH E-DCH Absolute Grant Channel E-DPCCH E-DCH Dedicated Physical Control Channel E-DPDCH E-DCH Dedicated Physical Data Channel E-HICH E-DCH

37、quence Number SG Serving Grant TSN Transmission Sequence Number 4 Background and Introduction The technical objective of the FDD Enhanced Uplink work item is to improve the performance of uplink dedicated transport channels, i.e. to increase capacity and throughput and reduce delay. This work item i
38、s applicable for UTRA FDD only. Among the techniques considered in 1, the following techniques are part of the work item: - Node B controlled scheduling: possibility for the Node B to control, within the limits set by the RNC, the set of TFCs from which the UE may choose a suitable TFC, - Hybrid ARQ
39、: rapid retransmissions of erroneously received data packets between UE and Node B, - Shorter TTI: possibility of introducing a 2 ms TTI. ETSI ETSI TS 125 309 V6.6.0 (2006-03) 8 3GPP TS 25.309 version 6.6.0 Release 6 5 Requirements - The Enhanced Uplink feature shall aim at providing significant enh
40、ancements in terms of user experience (throughput and delay) and/or capacity. The coverage is an important aspect of the user experience and that it is desirable to allow an operator to provide for consistency of performance across the whole cell area. - The focus shall be on urban, sub-urban and ru
41、ral deployment scenarios. - Full mobility shall be supported, i.e., mobility should be supported for high-speed cases also, but optimisation should be for low-speed to medium-speed scenarios. - The study shall investigate the possibilities to enhance the uplink performance on the dedicated transport
42、 channels in general, with priority to streaming, interactive and background services. Relevant QoS mechanisms shall allow the support of streaming, interactive and background PS services. - It is highly desirable to keep the Enhanced Uplink as simple as possible. New techniques or group of techniqu
43、es shall therefore provide significant incremental gain for an acceptable complexity. The value added per feature/technique should be considered in the evaluation. It is also desirable to avoid unnecessary options in the specification of the feature. - The UE and network complexity shall be minimise
44、d for a given level of system performance. - The impact on current releases in terms of both protocol and hardware perspectives shall be taken into account. - It shall be possible to introduce the Enhanced Uplink feature in a network which has terminals from Release99, Release 4 and Release 5. The E
45、nhanced Uplink feature shall enable to achieve significant improvements in overall system performance when operated together with HSDPA. Emphasis shall be given on the potential impact the new feature may have on the downlink capacity. Likewise it shall be possible to deploy the Enhanced Uplink feat
46、ure without any dependency on the deployment of the HSDPA feature. However, a terminal supporting the Enhanced Uplink feature must support HSDPA. 6 Overall architecture of enhanced uplink DCH 6.1 Protocol architecture The following modifications to the existing nodes are needed to support enhanced u
47、plink DCH: UE A new MAC entity (MAC-es/MAC-e) is added in the UE below MAC-d. MAC- es/MAC-e in the UE handles HARQ retransmissions, scheduling and MAC-e multiplexing, E-DCH TFC selection. Node B A new MAC entity (MAC-e) is added in the Node B to handle HARQ retransmissions, scheduling and MAC-e demu
48、ltiplexing. S-RNC A new MAC entity (MAC-es) is added in the SRNC to provide in-sequence delivery (reordering) and to handle combining of data from different Node Bs in case of soft handover. The resulting protocol architecture is shown in Figure 6.1-1: ETSI ETSI TS 125 309 V6.6.0 (2006-03) 9 3GPP TS
