RAN 4 Report RP-070277 Howard Benn

Summary: 

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.

Slide3: 

　 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 R99 – Rel-5 Highlights

Rel-6 Highlights: 

Rel-6 Highlights TEI-6

TEI - 7: 

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

TEI-8: 

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

Work and Study Items: 

Work and Study Items

Highlights: 

Highlights MIMO Work continues Low Chip rate E-DCH Simulation results presented CRs approved UE Antenna Performance Evaluation Method and Requirements Discussion continues Proposal to work with COST 2100 Follows on from COST273 LMU performance spec Simulation assumption presented Initial simulation results Work continues

Improved performance requirements: 

Improved performance requirements Further Improved Performance Requirements for UMTS/HSDPA UE (FDD) Dynamic reconfigurable receivers Questions raised on impact to network

Others: 

Others CPC Simulation results presented for ideal and implementation margin Demod performance CR approved 16 QAM uplink Work proceeding One more meeting cycle needed 64 QAM downlink Work proceeding Performance CRs approved Few issues – see status report One more meeting cycle needed

Slide11: 

MBSFN New channel model under discussion First set of simulations performed Type 3i performance requirements Discussed testing scenarios to reduce complexity UMTS 1500 TR approved Enhanced cell FACH testing Question over which release performance requirements should be in ?

Slide12: 

Interference mitigation study item Simulations showed limited performance improvements Agreed no need to standardise performance Home Node B Work started Conference call before the Orlando meeting to progress the work

LTE: 

LTE Close to being on schedule Channel options below 5 MHz 1.4 MHz and 3 MHz proposed by a number of companies but not agreed PHS co-existence Still working on a solution UE TR Baseline transmitter requirements agreed Baseline RF receiver performance agreed Channel models agreed Work plan for demodulation requirements agreed
