Special election of vice chair A special election for the position of a Vice Chairman of RAN WG4 was held during RAN4#56 in August. Dr. Dawei Zhang (China Mobile Com. Corporation / CCSA) was elected as a new vice chair of RAN4. We thank for Dr. Christian Bergljung (Telefon AB LM Ericsson / ETSI) for his every endovor as a vice chair of RAN4.

Working agreement on UMTS800 Eu The working agreement in RAN#48: CR0530r1 to TS 36.101 "E-UTRA; User Equipment (UE) radio transmission and reception" v9.3.0 in RP-100683. Modification in table 7.3.1-2 for the case E-UTRA Band 20 for the 10MHz channel bandwidth was the point. No voting would be necessary in RAN#49 since the interested parties had intensive discussions during the week of RAN4#56 in Madrid and agreed the way forward. Side information: CR617r1 to TS36.101 (in R4-103463) agreed in RAN4 as a separate category F CR, which further clarifies the receiver requirement.

Meeting statistics - One ordinary & one AH meeting were held since the last RAN plenary meeting - One ordinary and two ad-hoc meetings are planned before the next plenary. - RAN4 officials: Chair: Mr. Takaharu Nakamura, Fujitsu / ARIB Vice Chair: Mr. Edgar Fernandes, Motorola / ETSI Vice Chair: Dr. Dawei Zhang , China Mobile / CCSA MCC Support: Dr. Issam Toufik, ETSI Meeting Date Place Host Delegates Tdocs AdHoc #10-03 28 Jun – 2 Jul Bratislava, SK EF3 around 100 377 R4#56 23 – 27 Aug Madrid, ES around 120 714 Meeting Date Location Host Band 13 AH 29-30 Sep.

Adhoc #2010-03 in June 377 tdocs for limited subjects were submitted and handled. Tdocs agreed at the adhoc were reviewed in R4#56 and most of them were ratified (2 tdocs were replaced by revisited/updated version). Topics handled in the adhoc: Maintenance of closed WIs DC-HSDPA, DC-HSUPA, Conformance tests for Multi-Standard Radio (MSR), CSG reselection requirements, Enhanced Dual-Layer transmission for LTE Rel-10 WIs Carrier aggregation (IMT-A), Relay (IMT-A), 4 carrier HSDPA, UL-MIMO for LTE, Enhanced ICIC for non-CA in het-net for LTE , Fixed Wireless CPE, Two-antenna LCR TDD Type 1&2 UE Rx, UE OTA testing - LME Free Space test, MSR BS RF requirements for non-contiguous spectrum deployments, MIMO Testing in HSDPA New frequency bands / maintenance of existing bands (rel. independent) UMTS/LTE3500, L-Band LTE for ATC of MSS in North America, 2 GHz band LTE for ATC of MSS in North America, LTE TDD in 2600MHz for USA, Expanded 1900 MHz Band for UTRA and LTE, Band 20 maintenance, Band 12 maintenance Study Items Extending 850 MHz, Signaling and procedure for in-device coexistence interference avoidance

R4#56 in August Still higher work load in general. 714 tdocs were submitted. Decreasing gradually due to the adhoc discussions. Still higher work load is observed in several areas: Maintenance of the earlier releases etc. WIs/Sis which is planned to be completed by December were prioritized. Performance works in general were de-prioritized as the consequence. Sessions started from early morning (eg. from 8 am) and lasted till late evening. Some of the tdocs were covered only in the ad-hocs and some of the ad-hoc sessions were run in parallel. 73 tdocs were not handled and carried over to future meetings. As a whole, ad hoc in June and R4#56 have handled almost 1100 tdocs. Thanks for those participated from early morning to late evening sessions.

Work load analysis < R4#56 case > ‘Maintenance activities’ for earlier releases: almost 40% LTE-Advanced related works: 26%. Tdoc statistics in R4#56 Rel-7/8/9 maintenance work: 4% LTE maintenance: 24% MSR: 2% HNB: 7% LTE-Advanced (Rel-10): 27% Other Rel-10 18% New frequency bands 9 % Study items : 3 % Others: 6 % Number of tdocs per agenda items in R4#56

Work load analysis (cont’) < R4#56 case > - 73 tdocs out of 714 were ‘Not handled’. (Missing rate = 10.22%) - Simple linear interpolation tells us “RAN4 would need extra 2.1 days to cover all of its potential subjects’. (The meeting could be completed Monday morning next week).

Work load analysis (cont’) < Possible actions > Meeting arrangement plan: R4 AH in October: Limited technical discussions on Rel-10 WIs (eg. Core part of LTE-Advanced etc.) Possible parallel sessions R4#57 in November To review and ratify agreement in January AH. Possible parallel adhoc sessions Parallel Ordinary sessions (as a trial): Sessions to be chaired by the R4 officials. The parallel sessions would provide extra two or three meeting dates effectively. Earlier submission of your contributions would help the progresses very much.
