HSUPA Feature©2013 Nokia Solutions and Networks. All rights reserved. HSUPA Functional Description Background This feature provides the High Speed Uplink Packet Access (HSUPA) functionality, also known as Enhanced Uplink DCH (E-DCH). HSUPA functionality is based on the following techniques: BTS controlled scheduling of the E-DCH within the limits set by the RNC Physical layer retransmission handling in the BTS Objective Increased UL average and peak data rates improve the end user experience. CAPEX and OPEX savings result from increased cell UL capacity and increased Iub and BTS HW efficiency. New data service availability increases revenue 2 ©2013 Nokia Solutions and Networks. All rights reserved. HSUPA Dimensioning in RU30 Baseband Dimensioning HSUPA is supported only with co-existence of HSDPA All cells in the BTS can be enabled for HSUPA 1 HSUPA BTS processing set allows to reach up to 5.8Mbps per HSUPA scheduler with minimum number of users or 24 HSUPA users with minimum throughput Baseband reservation provided by one HSUPA BTS processing set equals to 1.5 subunit allocation With System Module Rel.2, one HSUPA scheduler can support up to 240 HSUPA users from 1 to 12 cells. One HSUPA scheduler can be allocated per LCG (or per System Module if frequency layer mapping to HW is used) If more than 240 HSUPA users is needed to be supported: Create two Local Cell Groups => up to 480 HSUPA users supported With two System Module rel.2 and frequency layers mapping to HW up to two HSUPA schedulers can be allocated per single LCG (note that frequency mapping to HW is possible only in one LCG scenario) =>up to 480 HSUPA users supported 3 ©2013 Nokia Solutions and Networks.

All rights reserved. Operator benefits This feature is technically required for the RAN 981: HSUPA 5.8 Mbps. if 2ms TTI is assigned to the UE. Mapping of SRBs on UL E-DCH enables the use of 2xSF2 + 2xSF4 code in UE to support uplink HSUPA bit rate up to 5. This feature introduces mapping of SRB on HSUPA but only with E-TTI = 2ms Requirement Software Requirement 30 ©2013 Nokia Solutions and Networks. All bit rates above 2 Mbps need TTI of 2ms on E-DCH. It also maps the SRBs (Signaling Radio Bearer) on HSUPA. . Immediate data processing in Iub and the RNC user plane also shortens RTT. 6 and 7 Shorter TTI improves average latency in radio interface by 12ms for the first transmission. Mapping the SRBs to HSUPA enables spreading code allocation of 2xSF2 + 2xSF4 in uplink which is needed if 5. Faster retransmissions also reduce variance of the Round Trip Time (RTT).
