Summary • 2 meetings since last RAN meeting • Adhoc in Sophia Antipolis, main meeting in Kobe • Consistent number of delegates (around 100) • 400 input contributions in Kobe • Corrections to the specification (cat B,C & F numbers) • Release 99 – CRs • Release 4 – CRs • Release 5 - CRs • Release 6 – CRs • Release 7 - CRs • There will be 2 WG meeting before the next plenary. RP-070277 Slide 1
R99 – Rel-5 Highlights • R99 • Category B spurious emission limits for TDD BS and repeater reflecting new limits agreed with CEPT/ECC • Rel – 4 • Rel – 5 • Correction to Node B test model • Corrections to low chip rate TDD HSDPA • Looking at a new method to measure the CQI reporting, this is probably take a few meetings to resolve RP-070277 Slide 2
Rel-6 Highlights • TEI-6 RP-070277 Slide 3
TEI - 7 • High speed train requirements • Uplink and downlink simulations completed • CRs with performance requirements approved • Correction of Test Case for Inter-system Handover from UTRAN FDD to GSM • Introduction of band X into the repeater specification • Repeater ACRR description • RRM test cases for UE with multiple receive antennas • Result of RAN 1 CR on linear average • Work needed to complete CR RP-070277 Slide 4
TEI-8 • Proposal to add 15 code 16 QAM requirements • Request to spec clock accuracy on IuB • Passed to plenary for discussion of which working group this falls under RP-070277 Slide 5
