3GPP TSG RAN1#116bis R1-240xxxx Changsha, China, April 15 19, 2024 Agenda Item: 9 Document for: Discussion and Decision On the CR drafting for ISAC and 7-24 GHz Xiaomi, AT&T, Intel, ZTE, Samsung
Background In R1-2402648, a proposal on how to incorporate outcomes of ISAC SI and 7-24GHz SI was given A further joint offline session on ISAC and 7-24GHz was held Based on the outcomes of the joint offline session, the proposals are updated
Conclusion (1) New functional inclusions and changes from ISAC and 7-24 GHz (i.e. near field and spatial non-stationarity) are suggested to be added to separate new (sub) sections. RAN1 may discuss further as needed if any other (sub)-section(s) would be amended, including the addition of separate new (sub) section(s), as part of the work for 7-24 GHz and ISAC. RAN1 will proceed with the two studies with the assumption that RAN1 will agree two separate CRs, one for each SI. Note: if certain function is not necessary, the related sub-section can be revisited later
Conclusion (2) For the outcome of validation, whether to replace legacy parameters or include them as additional/alternative parameter set will be determined later when study has progressed further. 7-24 GHz SI may introduce new (sub)-sections for additional component under section 7. [7.2 for scenario] 7.6.X Modelling of near-field propagation 7.6.Y Modelling of spatial non-stationarity propagation
Conclusion (3) New section 7.9 can be created for ISAC, with following sub-sections: 7.9.1 for scenarios 7.9.2 for additional components, at least the following would be considered object modeling including RCS aspects pathloss and LOS probability fast fading including target channel, [background channel] Method to combine the target channel and background channel spatial consistency [Mobility of Tx/target/Rx] 7.9.3 for LLS 7.9.4 for calibration [7.9.x is introduced, If ISAC impacts the section 8 of map-based model]
