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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 29-33, 35, 36, 38-45, 47 and 48 are rejected under 35 U.S.C. 103 as being unpatentable over Abdelghaffar et al. U.S. Patent Application Publication 2025/0240142, hereinafter Abdelghaffar, in view of Mei et al. U.S. Patent Application Publication 2024/0163057, hereinafter Mei.
Regarding Claim 29, Abdelghaffar discloses a method, performed by a wireless device operative in a wireless communication network having a legacy procedure for the generation, transmission, reception, and processing of Demodulation Reference Symbols (DMRS) and an extended procedure, different than the legacy procedure, for the generation, transmission, reception, and processing of DMRS (Abstract; Figure 2-5, 8-15; Paragraph [0118] New DMRS port mapping and legacy DMRS port mapping configurations), comprising:
obtaining an indication of an extended antenna port table that includes both legacy DMRS ports and extended DMRS ports (Figure 5 and 15; Paragraph [0110-0122] UE configured and signaling with multiple candidate DMRS port mapping tables including an indication of which DMRS port mapping table is to be used with various tables which may be extended modified to reflect both the legacy port mapping configuration and new DMRS port mapping configuration with re-purposing field values);
determining one or more DMRS ports from the extended antenna port table; and communicating with the network using the one or more determined DMRS ports (Figure 5 and 14; Paragraph [0118-0176] Control singling may indicate that the DMRS port mapping configuration corresponds to Table 7 above, and may further indicate antenna port field value=0. In this example, the UE 505 may receive the first DMRS including Codeword 0 using DMRS ports 0 and 1 corresponding to CDM group 0 in accordance with a first mapping for Codeword 0 defined by the DMRS port mapping configuration. Similarly, the UE 505 may receive the second DMRS including Codeword 1 using DMRS ports 2 and 3 corresponding to CDM group 1 in accordance with a second mapping for Codeword 1 defined by the DMRS port mapping configuration; That is the UE is configured and indicated reference port mapping tables and determines one or more DMRS ports from the extended antenna port table and utilizes those DMRS ports for communicating).
Abdelghaffar readily discloses both legacy DMRS ports and extended DMRS ports and indication signaling but may not explicitly disclose an extended antenna port table that includes both legacy DMRS ports and extended DMRS ports.
However, Mei more specifically teaches an extended antenna port table that includes both legacy DMRS ports and extended DMRS ports (Figure 14; Paragraph [0065-0066] the DMRS port index to indicate whether a DMRS port is a newly configured DMRS port or a legacy DMRS port. FIG. 10 illustrates an example of a table showing a number of DMRS CDM groups without data for DMRS type 2 for single symbol DMRS. In FIG. 10, the column ‘value’ from 0 to 31 corresponds to an entry of DCI signaling from the network side (e.g., gNB) to indicate, to the UE, which DMRS port is used. In FIG. 10, rank is 2 for new CDM group. As shown in FIG. 10, the DMRS ports of the legacy UE have indices greater than 11. If the indicated DMRS port has an index number between 0 and 11, the DMRS port corresponds to the legacy DMRS port. Thus, the DMRS port index can indicate whether the CDM group is mapped to 2 REs or not. If the indicated DMRS port has an index number between 0 and 11, the newly configured CDM groups #0 to #2 correspond to the legacy UE CDM groups #0 to #2. If the indicated DMRS port has an index number between 12 and 35, the CDM groups #0 to #2 correspond to the newly configured CDM groups #0 to 2, each CDM group with 2 REs per PRB. Thus, the DMRS port index can indicate whether the CDM group is mapped to 2 REs or not. . For example, as shown in FIG. 11, the number of DMRS CDM groups without date can be used to indicate whether the DMRS port is legacy DMRS port or new DMRS port).
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 teachings of Abdelghaffar with the teachings of Mei. The method enables providing feedback schemes for multiple channels in wireless communication devices in an efficient manner, thus reducing energy consumption and device cost, improving spectral efficiency, and reducing latency of the wireless communication device (Mei Abstract; Paragraph [0002-0006]).
Regarding Claim 30, Abdelghaffar in view of Mei disclose the method of Claim 29.

Regarding Claim 33, Abdelghaffar in view of Mei disclose the method of Claim 29. Abdelghaffar in view of Mei further disclose indexing a DMRS description table with the one or more DMRS ports to determine parameters associated with each of the DMRS ports; and wherein communicating with the network using the one or more determined DMRS ports comprises communicating with the network using the one or more determined DMRS ports and the determined parameters associated with each of the DMRS ports (Abdelghaffar Figure 5 and 14; Paragraph [0019] Control signaling includes a radio resource control (RRC) message, a medium access control-control element (MAC-CE) message, or both and the second control signaling includes a downlink control information (DCI) message; Paragraph [0246-0250] Preconfigured configurations stored in memory and indications received; Mei Figure 14; Paragraph [0082-0085] Antenna port indication is indicated using a radio resource control (RRC) signaling or a MAC control element, or a downlink control information).

Abdelghaffar in view of Mei further disclose obtaining an indication of a legacy antenna port table including only legacy DMRS ports; receiving, from the network, an indication of whether to use legacy antenna port table or the extended antenna port table; receiving, from the network, an index into the indicated antenna port table; and determining one or more DMRS ports from the indicated antenna port table (Abdelghaffar Paragraph [0110-0122] Legacy port mapping tables and new DMRS port mapping tables and control signaling indicating which port mapping table is used).
Regarding Claim 36, Abdelghaffar in view of Mei disclose the method of Claim 29. Abdelghaffar in view of Mei further disclose wherein receiving, from the network, an indication of whether to use the legacy antenna port table or the extended antenna port table comprises receiving the indication in a Control Element (CE) for a Media Access Control (MAC) (Abdelghaffar Paragraph [0019] Control signaling includes a radio resource control (RRC) message, a medium access control-control element (MAC-CE) message, or both and the second control signaling includes a downlink control information (DCI) message; Mei Paragraph [0085] Antenna port indication is indicated using a radio resource control (RRC) signaling or a MAC control element, or a downlink control information).
Regarding Claim 38, Abdelghaffar discloses a wireless device operative in a wireless communication network having a legacy procedure for the generation, transmission, reception, and processing Demodulation Reference Symbols (DMRS) and an extended procedure, different than the legacy procedure, for the generation, transmission, reception, and processing of DMRS, comprising: communication circuitry; and processing circuitry operatively connected to the communication circuitry (Abstract; Figure 2-5, 8-15; Paragraph [0118] New DMRS port mapping and legacy DMRS port mapping configurations),

However, Mei more specifically teaches an extended antenna port table that includes both legacy DMRS ports and extended DMRS ports (Figure 14; Paragraph [0065-0066] the DMRS port index to indicate whether a DMRS port is a newly configured DMRS port or a legacy DMRS port.

If the indicated DMRS port has an index number between 12 and 35, the CDM groups #0 to #2 correspond to the newly configured CDM groups #0 to 2, each CDM group with 2 REs per PRB. Thus, the DMRS port index can indicate whether the CDM group is mapped to 2 REs or not. . For example, as shown in FIG. 11, the number of DMRS CDM groups without date can be used to indicate whether the DMRS port is legacy DMRS port or new DMRS port).
