`Statistics/Executive Summary
`TSG RAN WG2 #63 was held in Jeju, Korea, co-located with RAN WG1, WG3, WG4 and WG5 two weeks before
`TSG RAN #41. The RAN WG2 meeting was split in 3 parallel sessions: LTE user plane (UP) Wed-Thu (see section
`6.1/Annex A or R2-084861), LTE control plane (CP) Wed-Thu (see section 6.2/Annex B or R2-084873) and UTRA
`session Mon-Thu (see section 7). Common parts were treated on Mon, (Tue) and Fri.
`
`
`181 participants
`
`1129 Tdocs allocated with actual 1030 available contributions
`
`42 incoming liaison statements (6 related to UTRA, 36 related to LTE/E-UTRA): 5 of them postponed
`
`23 outgoing liaison statements (3 related to UTRA, 20 related to LTE, 3 of 23 agreed by email)
`
`19 email discussions scheduled after RAN2 #63
` Among 480 change requests (CRs) in total: 149 CRs (89 for UTRA, 60 for LTE) agreed
` Vice chairman Richard Burbidge (RIM) was reconfirmed.
`
`Note: The sequence in which the different topics appear in this report is related to the agenda of the meeting. However,

`Opening of the meeting
`1
`TSG RAN WG2 chairman Gert-Jan van Lieshout (Samsung) opened the meeting RAN WG2 #63 on Monday morning

`
`On behalf of the host (Samsung) Kyeong in Jeong (Samsung) welcomed the delegates to Jeju and explained
`organisational issues.
`
`RAN WG2 meeting rooms:
`
`Main RAN2 room: Lotus 1/2 Hall (3rd floor), planned for 160 participants (later extended), Mon-Fri
`
`First ad hoc room: Weolla Hall (5th floor), for 50 participants, Mon-Thu
`
`2nd ad hoc room: Halla 2 Hall (5th floor), for 80 people, Tue-Thu (finally not used on Tue)
`
`Other RAN WGs:
`
`same location: RAN1: Halla 1 Hall (5 floor) +ad hoc: Lily Hall (3rd floor); RAN3: Lotus 3 Hall
`(3rd floor), RAN4: Camellia Hall (3rd floor) + ad hoc: Sara Hall (5th floor), RAN5: Halla 3 Hall
`(3rd floor) + ad hoc: Rose Hall (3rd floor).
`
`Call for IPR
`1.1
`Gert-Jan van Lieshout (TSG RAN WG2 chairman) made the following call for IPRs and reminded the delegates of their
`obligations with respect to IPRs:
`
`
`
`
`
`The attention of the delegates of this Working Group is drawn to the fact that 3GPP
`Individual Members have the obligation under the IPR Policies of their respective
`Organizational Partners to inform their respective Organizational Partners of
`Essential IPRs they become aware of.
`The delegates were asked to take note that they were hereby invited:
`
`
`to investigate whether their organization or any other organization owns IPRs
`which were, or were likely to become Essential in respect of the work of the
`work of 3GPP.
`to notify their respective Organizational Partners of all potential IPRs, e.g., for
`ETSI, by means of the IPR Statement and the Licensing declaration forms
`(http://webapp.etsi.org/Ipr/).
`
`
`
`NOTE:
`
`IPRs may be declared to the Director-General or Chairman of the SDO, but not to the RAN2 chairmen.

`UMTS/LTE common aspects
`
`Contributions submitted under this agenda item will be handled in a joint UMTS/LTE session. Documents should focus on Stage-2/3 aspects common
`for both UTRAN and E-UTRAN.
`
`Inter-RAT mobility UMTS<->LTE
`4.1
`Note that stage-3 proposals specific for UMTS should be submitted under 7.5.6, and specific for LTE under 6.2.1.5.
`
`R2-083837: Lifetime of dedicated cell reselection priorities T-Mobile Disc
`Nokia wonders about the text proposal: do we need the change in 5.2.9 ? If we have cleared
`them already, this should be clear ? Seems not to do any harm.
`Ericsson wonders if “common cell reselection priorities” is sufficiently clearly specified ? Tmob
`thinks maybe we should rephrase it to “priorities provided by BCCH”.
`Proposal 1:
`
`9 / 156
`
`SAMSUNG 1038-0009
`
`

`
`
`
`Report of TSG RAN WG2 #63, Jeju, Korea, August 18 – 22, 2008
`
`
`
`Nokia wonders about proposal 1: we have cell reselection in connected mode. So does it
`mean that the network has to provide the priorities immediately after the clearing so that
`he has them when he goes to PCH/FACH ? So could the clearing not be triggered by
`UTRAN rather than by the UE ? So this would mean a UTRAN that wants to clear the
`priorities should send an explicit message to clear the priorities.
`QC is wondering if a home-NB would be allowed to set these priorities ? E.g. if it is set by the
`home-NB and the macro is not aware of this home-NB. How would the macro know if it
`has to reset the priorities or not ? Also would the home-NB not have a better
`understanding than the macro.
`Tmob thinks that the home-NB is fully under control of the operator so he would be able to set
`the priorities provided by the home-NB as we like. QC wonders whether there is the case
`that the parameters are not available to the macro ? Tmob clarifies that the CN will
`provide sufficient information to the macro/home-eNB to set the priorities.
`Tmob assumes that only having the explicit clearing approach would only be applicable to
`UTRAN. There does not seem to be a reason to have this for LTE.
`Panasonic wonders about mobility between UMTS and LTE ? Tmob assumes that when the
`UE is handed over to LTE, the UE clears the priorities. So the network would have to
`provide it again when the UE goes from LTE to UMTS.
`=> Will have only explicit release by the UTRAN network (due to UE based mobility in
`connected mode), and will have automatic release by the UE when going to RRC-
`connected for LTE.
`Proposal 2:
`- Ericsson assumes this is managed by the CN to have TA-lists that not overlap ePLMN ?
`Tmob agrees that this will enforce the TAU at ePLMN boundary. Note that this proposal 2
`does not impact RAN behaviour.
`- Tmob assumes that dedicated priorities are only valid in the R-PLMN. So this should be
`clear. However Tmob assumes that e-PLMN’s are considered equivalent to the R-PLMN.
`=> Clarify the dedicated priority list is deleted when the UE selects a new PLMN (change
`between ePLMN’s is a cell reselection, not a PLMN selection)..
`Proposal 3:
`-
`Infineon wonders if the UE discards the priorities or not applies the priorities ? In the Tmob
`proposal, the priorities are cleared when the UE goes to any cell selection.
`- Samsung wonders if this would result in very fast clearing ?
`=> Can discuss this up to the next meeting.
`=> 36.304 CR for proposal 1 & 2 can be provided in R2-084704 CR0018
`=> Will see text proposal for 36.331 in R2-084707
`=> 25.304 CR for proposal 1 & 2 will be included in the 25.304 CR for LTE<->UMTS mobility
`(Tdoc R2-084295) in R2-084706 CR 0172 (come back in UMTS session)
`Note: R2-084705 was allocated to the revision of R2-083837 and then withdrawn as this
`was supposed to be covered in R2-084706.
`(Note: R2-084705 was temporarily misallocated (double allocation) in UP session to the
`revision of R2-084158, the correct revision of R2-084158 is in R2-084755.)
