`
`R1-073815
`
`Executive summary
`3GPP TSG WG RAN1 #49b meeting took place in Marriott Orlando World Center Resort, Orlando, Florida-USA.
`
`The meeting started at 9:20 on Monday 25th June and finished at 17:10 on Friday 29th June 2007.
`
`The week was scheduled as follows:
`
` Monday: Agenda items 1, 2, 3, 4, 5.1, 5.2 and 5.3
`
` Tuesday: Agenda items 5.8, 5.13.1 and 5.13.2
`
` Wednesday: Agenda items 5.5 and 5.6 – Parallel session (full day) for 5.10
`
` Thursday: Agenda items 5.9, 5.11.2 – Parallel session (4:00PM-7:00PM) for 5.10.4 – Cocktail at 7:00PM
`
` Friday: Agenda items 5.7, 5.4, 5.12, 5.11.1
`
`The meeting focused on LTE only discussions and progress. Therefore a set of Incoming Liaison Statements with regard to
`Release 7 Work items have been postponed to next 3GPP TSG WG RAN1 #50 meeting for further treatment.

`Opening of the meeting
`1
`Mr. Dirk Gerstenberger (RAN1 Chairman) welcomed the participants to the 49th RAN WG1 bis meeting and opened the
`meeting at 09:20.
`
`Mr. Sharat Chander from Cingular Wireless welcomed the delegates on behalf of the North American 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/).

`
`o ZC sequence length =63 and PSC sequence length =63 (including DC)
`o The root indices are M=n1, M=N-n1, M=n2
` N=63, n1=29, n2=25
`o Leave the remaining 9 sub-carriers reserved
`
`
`
`
`
` Way forward on SSC:
`o M-sequence based code
` Generate a set of 31 sequences obtained as cyclic shifts of a single length 31 M-sequence
`generated from the primitive polynomial x^5+x^2+1 over GF(2)
` Two short SSC codes selected from above set
`
`Interleaved multiplexing of two short SSC sequences.
`
`It is noted that whether to use the P-SCH as a phase-reference is an implementation
`issue
` First and second sequence scrambled with a binary scrambling code depending on the P-SCH
` FFS: Exact specification of scrambling code
` Scrambling of the second sequence with a binary scrambling code corresponding to the index of
`the first sequence. Many-to-1 relation between scrambling code and first sequence index is not
`precluded.
` FFS: Exact specification of scrambling code and relation of scrambling code to index
`of the first sequence
` Mapping onto sub-carriers: 31 length sequence + DC + 31 length sequence
` Leave the remaining 9 sub-carriers reserved
` BPSK mapping of binary sequence

`The document was presented by Zuo Zhisong from ZTE and shows the evaluation of two kinds of CP length blind
`detection methods for the TDD frame structure type 2, which are based on DL RS and S-SCH respectively.
`Discussion (Question / Comment):
`Decision: Document is noted.
`Conclusion: No change of current FS2. Correct DwPTS length (both for short and extended CP) in 36.211 Figure 2 to
`2560, remaining 12 samples added in the end of UpPTS.

`
`Summary of e-mail discussion on BCH physical-layer structure
`R1-073024
`The document was presented by Erik Dahlman from Ericsson.
`
`Ericsson
`
`
`
`Further to RAN1 #49 decisions regarding the BCH physical-layer structure, this document summarizes the email
`discussions since then and makes proposals for decision.
`Discussion (Question / Comment):
`Decision: Document is noted.
`Conclusions are as follows:
`
` The coded BCH transport block is mapped to four subframes (subframes #0) within a 40 ms interval
`
`
`
`40 ms timing is blindly detected, i.e. there is no explicit signalling indicating 40 ms timing.
`
` Coded BCH mapped to 4 OFDM symbols within a subframe. In case of extended CP, this implies a restriction in
`number of idle symbols in case of TDD FS type 1 to three idle symbols.
`

`
`
`
`16 shifts for NCS. Value of the shift FFS.
`
` Use a dedicated scheduling request channel.
`
`
`
