Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on February 04, 2026 has been entered, wherein claim 13 is cancelled, claims 1-12 and 14-20 are pending and ready for examination.
Response to Arguments
Applicant’s arguments with respect to the claims have been considered but are moot in view of the new grounds of rejection.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1, 6, and 16, are rejected under 35 U.S.C. 103 as being unpatentable over Matsumura et al. (Matsumura hereafter) (US 20210235453 A1) in view of Dou et al. (Dou hereafter) (US 20200235901 A1).
Regarding claim 1 Matsumura teaches, A method for wireless communication, the method comprising:
transmitting, to a user equipment (UE), a downlink control information (DCI) format 1-1 or 1-2 (DCI format 1_1) indicating a physical downlink shared channel (PDSCH) (PDSCH transmission … received by using the DCI) to the UE, wherein (Matsumura; [0078] By providing the RMI field/TCI field in the DCI (for example, DCI format 1_1) as described above, PDSCH transmission from a single transmission point or PDSCH transmission from a plurality of transmission points can be appropriately received by using the DCI) the PDSCH comprises [[two]] a transmission control indicator (TCI) codepoint comprising two TCI states (the base station reports “10” or “11” to the UE as the bit value of the DCI. [0096-0097] [0115] In contrast, a TCI configuration) corresponding to a plurality of demodulation reference signal (DMRS) antenna ports (CW 1/ DMRS port group 1 (DPG 1) may correspond to the PDSCH transmitted from the first transmission point, and CW 2/DPG 2 may correspond to the PDSCH transmitted from the second transmission point) (Matsumura; [0083]The base station may report whether PDSCH transmission is transmission from a single transmission point or transmission from a plurality of transmission points to the UE by using DCI. [0085] CW 1/DPG 1 may correspond to the PDSCH transmitted from the first transmission point, and CW 2/DPG 2 may correspond to the PDSCH transmitted from the second transmission point. [0093] When the PDSCH is transmitted from a plurality of transmission points (for example, in a case of NCJT), the base station reports “10” or “11” to the UE as the bit value of the DCI. [0097] [0104] TCI configuration 1 for CW 1/DPG 1 corresponding to TRP #1 and TCI configuration 2 for CW 2/DPG 2 corresponding to TRP #2 are configured in combination.);
a first TCI state of the two TCI states is uniquely associated (from a plurality of transmission points is configured) with a first set of DMRS antenna ports (on DPG 1 corresponds to beam 1) of the plurality of DMRS antenna ports (Matsumura; [0095] three measurement targets (sizes of a measurement set), and transmission from a plurality of transmission points is configured in each unit of transmission based on the DMRS port group DMRS port group (DPG). A case in which the size of the measurement set is 3 corresponds to a case in which, for example, three beams (beam 1, beam 2, and beam 3) are used. In this case, it may be assumed that transmission based on DPG 1 corresponds to beam 1);
a second TCI state of the two TCI states is uniquely associated with a second set of DMRS antenna ports of the plurality of DMRS antenna ports (Matsumura; [0095] …transmission based on DPG 2 corresponds to beam 2, and transmission based on DPG 3 corresponds to beam 3.); and
Matsumura fails to explicitly teach, a first number of DMRS antenna ports of the first set of DMRS antenna ports is equal to a second number of DMRS antenna ports of the second set of DMRS antenna ports
Dou teaches, a first number of DMRS antenna ports of the first set of DMRS antenna ports is equal to a second number of DMRS antenna ports of the second set of DMRS antenna ports (Dou; [0191]that the DMRS antenna port group 1 (the DMRS group index 1) includes the antenna ports {1000, 1001, 1002, 1003, 1004, and 1005}, the DMRS antenna port group 2 (the DMRS group index 2) includes the antenna ports {1006, 1007, 1008, 1009, 1010, and 1011}, ).

Regarding claim 6 Matsumura teaches, A method for wireless communication, the method comprising:

[0085] CW 1/DPG 1 may correspond to the PDSCH transmitted from the first transmission point, and CW 2/DPG 2 may correspond to the PDSCH transmitted from the second transmission point. [0093] When the PDSCH is transmitted from a plurality of transmission points (for example, in a case of NCJT), the base station reports “10” or “11” to the UE as the bit value of the DCI. [0096-0097], [0104] TCI configuration 1 for CW 1/DPG 1 corresponding to TRP #1 and TCI configuration 2 for CW 2/DPG 2 corresponding to TRP #2 are configured in combination.);

A case in which the size of the measurement set is 3 corresponds to a case in which, for example, three beams (beam 1, beam 2, and beam 3) are used. In this case, it may be assumed that transmission based on DPG 1 corresponds to beam 1);
a second TCI state of the two TCI states is uniquely associated with a second set of DMRS antenna ports of the plurality of DMRS antenna ports (Matsumura; [0095] …transmission based on DPG 2 corresponds to beam 2, and transmission based on DPG 3 corresponds to beam 3.); and

[0085] CW 1/DPG 1 may correspond to the PDSCH transmitted from the first transmission point, and CW 2/DPG 2 may correspond to the PDSCH transmitted from the second transmission point. [0093] When the PDSCH is transmitted from a plurality of transmission points (for example, in a case of NCJT), the base station reports “10” or “11” to the UE as the bit value of the DCI.

Only a single RV per DMRS port group is assumed in this example where RV(s) associated with different DMRS port groups are separated by ‘,’. It should be noted that this embodiment can also be extended to the case where two RV(s) are associated with a DMRS port group containing more than one port.) (given in Table 5).

wherein the capability report comprises information indicating an ability of the UE to receive the DCI format
Muruganathan further teaches, further comprising transmitting a capability report of the UE,
wherein the capability report comprises information indicating an ability of the UE to receive the DCI format (Muruganathan; [0107] the association between DMRS port group(s) and RV(s) are configured to the UE via at least RRC signaling. In some further embodiments, the TCI field in DCI format 1_1 is used for joint signaling of DMRS port group(s) and associated RV(s)).
