How to combine large scale parameters may be up to UE implementation, therefore, gNB only needs to inform two QCL RSs to the UE for the single layer SFN transmission.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of KHOSHNEVISAN and Wang, by including wherein the first SFN scheme indicates that a downlink signal corresponds to multiple QCL information, wherein the second SFN scheme indicates that different downlink signals correspond to different QCL information, respectively, and wherein the third SFN scheme indicates that a downlink signal from multiple transmission points corresponds to same QCL information., as taught by 3GPP, in order to estimate a downlink channel state according to the multiple QCL information (see 3GPP ( page 7,lines 26-29) and(page 8, lines 8-12)) .
Regarding claims 35, 34,33and 32, the combination of KHOSHNEVISAN, Wang ,3GPP and Chervyakov disclose all features with respect to claims 1,15,23 and 26, respectively
The combination of KHOSHNEVISAN and Wang does not disclose wherein the same downlink signal port corresponds to multiple QCL information, and wherein the different downlink signal ports correspond to different QCL information
3GPP discloses disclose wherein the same downlink signal port corresponds to multiple QCL information ( page 7,lines 26-29) (SFN transmission, multiple TRPs transmit the same TB with the same single layer and UE derives QCL properties (e.g., Doppler shift, Doppler spread, average delay, delay spread) from QCL RS that multiple TRPs transmit at the same time and uses them to estimate channel from single DMRS port),and
wherein the different downlink signal ports correspond to different QCL information (page 8, lines8-12) UE is configured with two TCI states corresponding TRP 1 and TRP 2, respectively. UE derives QCL properties of TRP 1 from the first TCI state and uses them to estimate channel from DMRS port 1 of TRP 1 and derives QCL properties of TRP 2 from the second TCI state and uses them to estimate channel from DMRS port 2 of TRP 2.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of KHOSHNEVISAN and Wang, by including wherein the same downlink signal port corresponds to multiple QCL information, and wherein the different downlink signal ports correspond to different QCL information, as taught by 3GPP, in order to estimate a downlink channel state according to the multiple QCL information (see 3GPP ( page 7,lines 26-29) and(page 8, lines 8-12)) .
Response to Remarks/Arguments
-Applicant’s argument with respect to the pending claims have been fully considered, but they are not persuasive for at least the following reasons. Applicant’s amendment to claims necessitated the new ground(s) of rejection presented in this Office action. Therefore, Applicant's arguments with respect to the amended claims have been considered but are moot in view of the new ground(s) of rejection.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
