Welcome to the latest edition of TSG Highlights! The aim is to provide you with a concise summary of the decisions and actions of the most recent 3GPP Technical Specification Group meetings held in June 2006 in Warsaw (Poland).
3GPP has four TSGs: CT (Core Networks and Terminals); RAN (Radio Access Network); SA (Services and Systems Aspects) and GERAN (GSM EDGE Radio Access Network). This summary reports on the first three of these, as GERAN meetings take place separately from the other TSGs.
Please note, these summaries do not constitute formal, approved reports of the meetings – they are opinions only and also may not be complete. They are offered for guidance only.
The meeting was hosted by the European friends of 3GPP in Warsaw, Poland on the 31st of May to the 2nd of June 2006.
The meeting approved 312 CRs, which is 25 less than the previous time. The trend of CR count is shown in the table below

As can be seen, the Rel-8 work hasn’t been started in CT yet, but the first work item description was approved in this meeting.
Rel-6 and Rel-7 CR counts did not behave this time quite as expected, but it does not mean that CT would be going back to Rel-6 maintenance mode. USIM test cases have been shifted to Rel-6 only, which unavoidably puts up the the Rel-6 CR count a bit. The WGs will have more meeting time in the next plenary period, so also the Rel-7 CR count is expected to rise by CT #33.
For the first time we can report that there were no R99 CRs!!!
CT4 have agreed to replace the automatically generated ASN.1 description in 24.080 and 29.002 with a reference. The CRs will be provided in the next meeting

Two documents for submission to ITU were approved: The initial submission towards M.1457 Revision 7 (RP-060422) and the response regarding the draft ITU recommendation on broadband wireless access systems (RP-060421). Final approval of this one will be delayed to the end of June 2006.
No CRs have been presented for Rel 99 and Rel-4.
A set of CRs for TDD spurious emissions for the Japanese PHS band was presented as company contributions. They were not approved, there is a need to study the co-existence aspects of the operation of PHS in the TDD band, recently approved in China (RP-060394).
A proposal for a new Node B measurement of the UL interference rise due to EDCH was presented. Some companies argued that a new measurement is not required, since the load information can be derived from existing measurements, and furthermore, it will add unnecessary complexity. For the supporting companies, the existing measurements do not provide enough granularity and accuracy. Consensus could not be found, the two sides are invited to get further discuss the issue and get agreement or additional support.
TR 25.914 Measurements of Radio Performances for UMTS Terminals in Speech Mode was approved (RP-060301).
The WI Additional minimum UE performance requirement for downlink physical channels in support of DCH/HS-DSCH operation based on type 1 enhanced receiver (Rx-Diversity) was closed, although CRs may be presented in the future to cover the F-DPCH.
There was discussion on closing the WI Delay optimization for procedures applicable to CS and PS Connections and on its Release of applicability. It was agreed that no more work can be presented to Rel-6 under this WI, and that it would remain open until September, when it will be replaced by a Rel-7 Item with very precisely identified objectives.
The group approved the proposal for MIMO from WG1: the PARC scheme will be used for TDD, and a dual-codeword MIMO based on D-TxAA will be used for FDD. However, it was not possible to reach agreement on the reference receiver and other details of the D-TxAA proposal. WG1 is asked to try to agree on the details in order to have a clear standardization proposal in the next meeting.
The work on 7.68 Mcps TDD was completed with the presentation of the CRs and TR from WG4. It was decided however to keep the Feature open until the WI for testing in WG5 is introduced.
TR 25.829 7.68 Mcps TDD Option: RF Transmission/Reception, System Performance Requirements and Conformance Testing was approved (RP-060298).
TS 25.319 Enhanced Uplink: Overall description; Stage 2 was approved (RP-060274).
The last set of CRs under the WI UE Performance Requirements for MBMS were approved. It was decided however to keep the item open until WI for testing in WG5 is introduced.
TS 34.229-1 and 34.229-2, IP multimedia call control protocol based on SIP and SDP; User Equipment (UE) conformance specification, were approved and put under change control in Release-5.
The WI Conformance Test Aspects UMTS 1.7/2.1 GHz Band was completed.
The WI Conformance Test Aspects Improved Performance of HSDPA Receiver type 3 was completed.
The study on Performance Evaluation of the UE behaviour in high speed trains with speeds up to 350 kmph was completed.
Due to the lack of work, it was agreed to close the Study on Performance Improvements in Small Cells using HSDPA/HSUPA.
There was some discussion regarding the HSPA evolution Study. Some companies suggested that a clear set of objectives should be agreed to avoid discussing too many divergent proposals, since this would need a long time to reach agreements. As a way forward, the skeleton of the Study TR will be discussed in the email reflector in order to start framing the study.
The following TRs were approved:
- TR 25.813 on E-UTRAN Protocol Architecture (RP-060390)
- TR 25.814 Physical Layer Aspects for Evolved UTRA (RP-060347)
- TR25.912 Feasibility Study for Evolved UTRA and UTRAN (RP-060430)
The way forward on LTE was extensively discussed. The Study was scheduled for completion at this meeting, but several companies (most operators included) believed that the objectives had not been achieved and that further simulations were required. Other companies believed that that part of the work could be done within the Work Item phase. It was agreed to keep the Study open until September and to approve the Feature description of the LTE; the descriptions of the Building Blocks were presented but will be considered by the WGs before approval in September.
The relation with SAE in SA WG2 was studied. A document was drafted highlighting the SAE topics that need to be prioritized in order to let the RAN group progress. (RP-060425)
The following Work Items were approved
- 3G Long-Term Evolution (Feature level WI) (RP-060426)
- UMTS 2.6 GHz 7.68 TDD (RP-060349)
- Interface to Control Tower Mounted Amplifiers (TMAs) (RP-060418)
- UE conformance testing for FDD Inter-Band Operation (RP-060272)
- RF/RRM Conformance Test Aspects MBMS (RP-060273)
The meeting was hosted by the European friends of 3GPP in Warsaw, Poland on the 5th of May to the 7th of June 2006.
Dear Colleagues,
Please find below my summary of major decisions from SA#32. It serves to highlight key agreements reached during the meeting and forms the basis of the summary of the SA meeting on the 3GPP web site. I have not included the specific guidance to the SA WGs as the WG chairs and MCC provide that guidance to the WGs. Please let me know any errors or omissions.
The System Architecture Evolution (SAE) study is proceeding but has not yet completed. The target date was slipped to SA#33. A detailed workplan was agreed for completion of the study (SP-060436). In preparation for the transition from study to normative work, a feature level work item was agreed to cover the normative work resulting from the study (SP-060411). The first step is to document the SAE requirements extracted from the AIPN work. SA2 was also tasked with developing a proposal for the building blocks required in 3GPP for this normative work.
A requirement was approved in 3GPP for support of a high speed UICC interface. The requirement is part of Rel 8 but specified to be release independent. The further specification of this interface will occur in SCP and/or TSG-CT.
A5/2 was removed from the 3GPP specs.
A LS was received from MSG indicating that operators were favoring an inband modem solution for eCall. The issue of whether eCall must be supported with or without a SIM has not yet been resolved by the regulators. SIM vs SIMless has major requirements and architectural implications so no specific action was taken by 3GPP SA on eCall.
3GPP is coordinating with TISPAN on various fronts. A LS was sent to TISPAN urging further coordination (SP-060447). Various CRs required by TISPAN and Cablelabs were approved. In addition it was agreed to hold a workshop on IMS alignment and evolution immediately after SA#33 (SP-060371). The workshop is primarily to address TISPAN and Cablelabs coordination, however the invitation will also be extended to several other standards organizations active in NGN,
The target date for freezing of the Rel 7 stage 2 specifications was shifted to SA#33.
It was agreed that Phase 2 and Rel 96 should be closed (pending GERAN agreement). This means that no further CRs are permitted to Phase 2 and Rel 96 specifications.
The source field in the current CR was split into "Source to WG" and "Source to TSG" fields (pending GERAN agreement) to distinguish WG agreed CRs and company sourced CRs at the plenary. The new CR cover sheet will not take effect until after SA#33. A discussion of when CRs should be allocated in the WG was deferred until next meeting.
The 2007/2008 plenary scheduled agreed (SP-060405). This respects the principle of ensuring that there is a gap of at least 10 weeks between plenaries.
The following New TRs were approved: TR 32.806 Application guide for use of IRPs on Peer-to-Peer Interface (SP-060262), TR 22.953 Multimedia Priority Service Feasibility Study (SP-060328), TR 35.919 UEA2 and UIA2 Design and Evaluation Report (SP-060422).
The following New TSs were approved: TS 35.215, TS 35.216, TS 35.217, TS 35.218 (SP-060422). All these specifications (including also TR 35.919 listed in the previous paragraph) are related to the specification of the UEA2 and UIA2 algorithms.
Several new work items (WIDs) were approved: Multimedia Priority Service (SP-060330), CSI Terminating Session handling (SP-060437), Packet Switched Streaming Enhancements (SP-060361), Alternate Charged Party (ACP) for IMS (SP-060442). In addition a WID was approved starting the normative work associated with SAE (SP-060411).
Several WIDs were updated. LCS for 3GPP Interworking WLAN (SP-060291) was updated to include emergency calls and updated completion dates. Voice call continuity between CS and IMS (incl. I-WLAN) (SP-060292) and Identification of Communication Services in IMS (SP-060293) were updated to include SA5 aspects. GAA usage extensions and optimizations (SP-060429) was updated to include shifted dates and SA5 aspects. The WID on HSDPA performance measurements (SP-060397) was updated to include TDD aspects.
Several new studies were started (SIDs): Study on Common Profile Storage Framework of User Data for network services and management (SP-060263), IMS Service Brokering (SP-060443), Study of VCC support for Emergency Calls (SP-060290), Multimedia Conferencing (SP-060332), Support for a Public Warning System (SP-060333), Protection against SMS and MMS spam (SP-060446)
Several SIDs were updated. Customized Alerting Tones (SP-060327) was updated with minor editoral changes, Multimedia Priority Service (SP-060329) was updated to reflect the scope and status of the study. Network Composition WID (SP-060331) was updated with revised target dates.
