hspa+ 42 program

HSPA+ 42 Summary of RequirementsEricsson RAN:

RAN software level: W10B

Features to be enabled: Dual Carrier HSDPA

Node B Hardware: 3xFU, 3xRU, RAX2e depending on the site

RNC Hardware: 18xSPB3 boards per RNC

Licenses: HS Code Expansion

NSN RAN: OSS: CD3

RAN Software level: RU20 PP2.11

Features to be enabled: Dual Carrier HSDPA, UL Interference Cancellation

Hardware: 2nd carrier kit for 40W (1xAdditional FRIA, 1x Additional FPBA)

Licenses: NodeB licenses for new features, plus 3x2nd carrier license per sector

Spectrum Contiguous 10 + 10 MHz

SGSN & GGSN: Licenses for 42M support (SGSN) and 48M support (GGSN)

HLR: Rule to modify Max bitrate of Dual Carrier TACs to 50 Mbps

Enhanced E.I.R. Dependency

Harmony Proxy Special profile to support 42 Mbps bitrate (TCP window settings, etc.)

AAV: Upgrade NodeB Ethernet capability to 50 Mbps, not a requirement for DC launch,

but needed for 42 Mbps data max speed.

Need for Additional T1’s will be reviewed on a case by case basis

Non - Gating Items

DUW30:

Proceeding with 2nd Carrier Installations, Activations, & Optimization while DUW30 clears FOA/GA and supplies are determined

2ms TTI:

Not a technical requirement for Dual Carrier

E/// - Approx 50% of RBS configured by Ericsson Services with 2ms TTI activated. Rest of sites to be upgraded by TMO as part of BAU.

NSN - Feature GA but issues with Samsung Vibrant prevented the rollout. PP2.11 will allow the rollout to continue without issue. 2ms TTI will be rolled out with PP2.11.

Continuous Packet Connectivity (CPC):

E/// - Roll out as soon as nodeB SW load CU3 is rolled out

NSN - Feature released last year, but with issues, MP3 SW and PP2.11 expected to fix, following RU20 rollout

DUW30 – New Card in RBS that replaces the CBU and ETMFX11 transport card

FOA currently ongoing in Vegas. Issues with HW availability from EricssonRisk – DUW30 is not GA yet. SW version to support DUW may change.

HSDPA Dual Carrier feature (Requires 2nd Carrier deployed on RBS)

FOA exit, with Ericsson MOP, was on 1/24. GA target is 1/28. Initially we may use E/// MOP and services. Transition to an internal TMO MOP and tool may be by end Feb 2011. Feature Requires 2nd carrier to be deployed and this is probably the biggest hurdle (work entails 2nd carrier HW deployment,2nd carrier optimization and possible cell max antennas and MCPA deployment).
