Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claim 1 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 11,848,803 in view of Breiling et al. (Pub. No.: US 20170163452 A1), hereafter referred to as Breiling. Although the claims at issue are not identical, they are not patentably distinct from each other because both conflicting claims recite the UE to: obtain channel information for a sidelink channel between the UE and a receiving device; perform, based on the channel information, a pre-equalization process on a signal to be transmitted to the receiving device to obtain a pre-equalized signal; and transmit, through the sidelink channel, the pre-equalized signal to the receiving device.
Claim 1 of U.S. Patent No. 11,848,803 fails to clearly recite An apparatus of wireless communication at a user equipment (UE), comprising: at least one memory; and at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor, is configured to cause the UE, wherein the UE is configured to perform at least a portion of processing offloaded from the receiving device.
Breiling teaches An apparatus of wireless communication at a user equipment (UE) (user equipment 10, Para. 77, FIG. 3), comprising: at least one memory (machine readable carrier, Para. 365); and at least one processor (signal processor 68, Para. 86, FIG. 3) coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to cause the UE to (program code being operative for performing one of the methods when the computer program product runs on a computer.

The SUDAC 30 with the frontend channel pre-equalizer 92 being remotely configured by the user equipment 10. Therefore, the user equipment 10 may transmit a configuration signal 46 in a frontend control portion 40 to the SUDAC 30. The SUDAC 30 extracts the configuration signal 46 comprising e. g. filter coefficients or filter indices, which can be applied by the frontend channel pre-equalizer 92, Para. 94, FIG. 6).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Breiling with the limitations of claim 1 of U.S. Patent No. 11,848,803 since Breiling provides a technique for user equipment to perform a channel estimation and adapt receiving parameters and signal processing parameters for configuring a channel pre-equalizer of a separate device, which can be introduced into the limitations of claim 1 of U.S. Patent No. 11,848,803 to permit a first device to perform certain pre-equalization techniques that generate values, which can be utilized by a second device conducting communications with the first device.

The SUDAC 30 with the frontend channel pre-equalizer 92 being remotely configured by the user equipment 10. Therefore, the user equipment 10 may transmit a configuration signal 46 in a frontend control portion 40 to the SUDAC 30. The SUDAC 30 extracts the configuration signal 46 comprising e. g. filter coefficients or filter indices, which can be applied by the frontend channel pre-equalizer 92, Para. 94, FIG. 6).

In regard to Claim 30, Horn teaches receiving the pre-equalized signal comprises: receiving the pre-equalized signal (At 335, the first device 305 may transmit, to the second device 310, the pre-equalized signal over the channel, Para. 123, FIG. 3) via a set of orthogonal frequency division multiplexing (OFDM) (Signal waveforms transmitted over a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)), Para. 75) symbols (In a system employing MCM techniques, a resource element may include one symbol period, Para. 75) using a sub-band full duplex (SBFD) scheme or a frequency division duplex (FDD) scheme (A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration.

Claim(s) 7-9 and 22-24 is/are rejected under 35 U.S.C. 103 as being unpatentable over Horn in view of Breiling, and further in view of Arool Emmanuel et al. (Patent No.: US 11863359 B1), hereafter referred to as Arool.

Although Horn in view of Breiling teaches receive (Rx) channel information associated with the sidelink channel, Horn in view of Breiling fails to teach channel state information (CSI).
Arool teaches receive (Rx) channel state information (CSI) (a client device requires channel state information (CSI) feedback to the transmitter, Col. 2, lines 44-49. The subcarrier pre-equalization logic 102 receives feedback data 111 from a second device with which the electronic device 100 is communicating. Using the feedback data 111, the subcarrier pre-equalization logic 102 adjusts the specific subcarriers' amplitudes corresponding to the second device's instantaneous feedback, Col. 4, lines 40-50. Values or gain code coefficients can be sent in the feedback data 111, Col. 8, lines 58-60).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Arool with the teachings of Horn in view of Breiling since Arool provides a technique to utilize CSI feedback data for pre-equalization logic to adjust signals for transmission, which can be introduced into the arrangement of Horn in view of Breiling to permit a second device to send CSI feedback data within a configuration message to inform a first device to begin utilizing certain pre-equalization parameters.
In regard to Claim 8, Horn teaches to obtain the channel information, the at least one processor is configured to cause the UE to: receive, from the receiving device, a set of receiving samples (The time intervals for the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of TS=1/(Δƒmax . Nƒ) seconds, Para. 76, FIG. 1. Each frame may include a variable number of slots. Each slot may include a number of symbol periods. Each symbol period may contain one or more (e.g., Nƒ) sampling periods, Para. 77) based on the dedicated reference signal (channel estimation procedures may include the transmitting device transmitting one or more reference signals to the receiving device, where the receiving device may measure the one or more reference signals and transmit information about the one or more measurements to the transmitting device, Para. 99).
Horn teaches identify, based on the set of receiving samples (The time intervals for the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of TS=1/(Δƒmax .

Each symbol period may contain one or more (e.g., Nƒ) sampling periods, Para. 77), the Rx channel information associated with the sidelink channel (the receiving device may measure the one or more reference signals and transmit information about the one or more measurements to the transmitting device, Para. 99).
Although Horn in view of Breiling teaches identify, based on the set of receiving samples, the Rx channel information associated with the sidelink channel, Horn in view of Breiling fails to teach Rx CSI.
Arool teaches identify, based on the set of receiving samples (The block of N output samples from the N-point IFFT 312 make up a single OFDM symbol, Col. 9, lines 31-33. When the N-point IFFT 312 is completely loaded, the Inverse FFT is computed, giving a set of complex time-domain samples representing the combined OFDM subcarrier waveform, Col. 10, lines 4-7. The outputs of the IFFT are time-domain samples, Col. 16, line 9), the Rx CSI (a client device requires channel state information (CSI) feedback to the transmitter, Col. 2, lines 44-49. The subcarrier pre-equalization logic 102 receives feedback data 111 from a second device with which the electronic device 100 is communicating. Using the feedback data 111, the subcarrier pre-equalization logic 102 adjusts the specific subcarriers' amplitudes corresponding to the second device's instantaneous feedback, Col. 4, lines 40-50. Values or gain code coefficients can be sent in the feedback data 111, Col. 8, lines 58-60).

In regard to Claim 9, Horn teaches to obtain the channel information, the at least one processor is configured to cause the UE to: receive, from the receiving device, the Rx channel information associated with the sidelink channel, wherein the Rx channel information is based on the dedicated reference signal (channel estimation procedures may include the transmitting device transmitting one or more reference signals to the receiving device, where the receiving device may measure the one or more reference signals and transmit information about the one or more measurements to the transmitting device, Para. 99).
Although Horn in view of Breiling teaches receiving device, the Rx channel information associated with the sidelink channel, wherein the Rx channel information is based on the dedicated reference signal, Horn fails to teach Rx CSI.
Arool teaches Rx CSI (a client device requires channel state information (CSI) feedback to the transmitter, Col. 2, lines 44-49.

Although Horn in view of Breiling teaches the channel information includes receive (Rx) channel information associated with the sidelink channel, Horn in view of Breiling fails to teach channel state information (CSI).
Arool teaches receive (Rx) channel state information (CSI) (a client device requires channel state information (CSI) feedback to the transmitter, Col. 2, lines 44-49. The subcarrier pre-equalization logic 102 receives feedback data 111 from a second device with which the electronic device 100 is communicating.

In regard to Claim 23, Horn teaches the at least one processor is further configured to cause the receiving device to: obtain, based on the dedicated reference signal (channel estimation procedures may include the transmitting device transmitting one or more reference signals to the receiving device, where the receiving device may measure the one or more reference signals, Para. 99), a set of receiving samples (The time intervals for the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of TS=1/(Δƒmax . Nƒ) seconds, Para. 76, FIG. 1. Each frame may include a variable number of slots. Each slot may include a number of symbol periods. Each symbol period may contain one or more (e.g., Nƒ) sampling periods, Para. 77), wherein to transmit the channel information (transmit information about the one or more measurements to the transmitting device, Para. 99), the at least one processor is configured to cause the receiving device to: transmit, to the UE, the set of receiving samples (The time intervals for the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of TS=1/(Δƒmax . Nƒ) seconds, Para. 76, FIG. 1. Each frame may include a variable number of slots. Each slot may include a number of symbol periods. Each symbol period may contain one or more (e.g., Nƒ) sampling periods, Para. 77).
