`Mr. Dirk Gerstenberger (RAN1 Chairman) welcomed the participants to the 52sd RAN WG1 meeting and opened the
`meeting at 09:10.
`
`Mr. Enrico Buracchini from Telecom Italia welcomed the delegates on behalf of the European Friends of 3GPP.
`
`Call for IPR
`1.1
`The Chairman drew attention to Members’ obligations under the 3GPP Partner Organizations’ IPR policies. Every
`Individual Member organization is obliged to declare to the Partner Organization or Organizations of which it is a
`member any IPR owned by the Individual Member or any other organization which is or is likely to become
`essential to the work of 3GPP.
`
`
`The attention of the members of this Technical Specification 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 members take note that they are hereby invited:
`
`to investigate in their company whether their company does own IPRs which are, or are likely to become
`Essential in respect of the work of the Technical Specification Group.
`
`to notify the Director-General, or the Chairman of their respective Organizational Partners, of all
`potential IPRs that their company may own, by means of the IPR Statement and the Licensing declaration
`forms (e.g. see the ETSI IPR forms http://webapp.etsi.org/Ipr/).

`On Uplink coverage for LTE

`concludes in favour of TTI bundling.

`Performance Comparison of Solutions for Subframe Bundling
`R1-080913
`The document was presented by Rainer Bachl from Alcatel-Lucent and addresses the two possible solutions for the issue
`with uplink coverage for LTE (performance comparison). Conclusions are:
`
` Alternative 2 provides a 1-3 dB coverage improvement compared to Alternative 1 for VoIP
`
` Unlike Alternative 1, Alternative 2 allows LTE VoIP to achieve similar coverage compared to HSUPA VoIP
`(10ms TTI), which is necessary in overlay scenarios
`
` Alternative 2 should be chosen as the solution to improve LTE uplink coverage
`Discussion (Question / Comment):
`Decision: Document is noted.
`
`
`Alcatel-Lucent
`Implications of Solutions for Subframe Bundling
`R1-080914
`The document was presented by Rainer Bachl from Alcatel-Lucent. As both proposed solutions for the issue with uplink
`coverage for LTE make use of subframe bundling, this contribution discusses possible implications of the subframe
`bundling solutions on the standards specification.
`Discussion (Question / Comment):
`Decision: Document is noted.
`
`Based on above set of contributions, Mr Chairman suggested informing RAN2 about RAN1 discussions mainly on
`Subframe bundling including Qualcomm’s comment, namely as follows:
`
` Subframe bundling is beneficial for coverage
`
`
`
`3 different alternatives are proposed
`
` One semi-static configuration of number of subframes in a bundle
`o Minimize the number of semi-static configurations of number of subframes in a bundle
`o on/off signalling of bundling
`Note: Code rate >1 is not precluded by this decision for first HARQ transmission (this needs to be discussed separately as
`part of MCS discussions)
`
`Tdoc number allocated to the LS shall be R1-081053.

`Reducing smallest E-TFCI value
`R1-080806
`The document was presented by Sharad Sambhwani from Qualcomm and evaluates the link level performance of reducing
`the smallest E-TFCI values as well as the L2 implications of MAC segmentation.
`
`As a conclusion, both the Link Budget analysis and MAC segmentation study indicate that there is no benefit of reducing
`the transport block sizes beyond 120 bits. In particular it is sufficient to segment the AMR Full Rate frame (VoIP or CS
`Voice over HS) into 3 segments of 120 bits each. It is no point trying to optimize segmentation of the SID frames, since the
`cell edge boundary must support transmission of full rate frames.
`Discussion (Question / Comment):
`Decision: Document is noted. This topic can be revisited if requested after having further discussed with RAN2.
`Friday 15th
`Conclusion: There is no agreement for reducing smallest E-TFCI.
`
`
`Ericsson
`HS-SCCH orders for HS-SCCH-less operation
`R1-080904
`The document was presented by Johan Bergman from Ericsson and proposes to introduce HS-SCCH orders for activation
`and deactivation of HS-SCCH-less operation, so that the HSDPA scheduler in the serving NodeB can signal dynamically
`to the UE whether HS-SCCH-less operation is required or not (to avoid unnecessary UE battery consumption).
`
`Ericsson is willing to discuss the way making the change either as a Rel-7 correction or as a part of the ongoing Rel-8
`work item on UE DRX enhancements.

`Initial Multi-Carrier HSPA performance evaluation
`R1-080902
`The document was presented by Johan Bergman from Ericsson and addresses some aspects of a potential multi carrier
`(MC) operation of a HSPA system. The paper concludes that higher data rates are achievable for most users, including
`users experiencing low and moderate SNR, resulting in more users having access to high data rates. Furthermore, due to
`scheduling gains, the system capacity is also expected to be increased compared to system where the carriers are used
`independently.
`Discussion (Question / Comment): Nokia raised concern on the number of users used for the performance simulation.

`On the introduction of a second UE DRX cycle in CELL_DCH
`R1-080903
`The document was presented by Johan Bergman from Ericsson and discusses some concerns with R1-080387, “Enhanced
`UE DRX for CELL_DCH state”, proposed by Nokia Siemens Networks, Nokia.
`Discussion (Question / Comment): NSN acknowledged all the observations made in the paper and agreed on the
`necessity for elaborating further the introduction of a second UE DRX cycle in CELL_DCH.
`Decision: Document is noted.
`
`Conclusion: Second DRX cycle for cell_DCH is not recommended by RAN1.
