Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
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.
Claims 4 and 6 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Omer et al. [US 20240372749 A1] hereinafter Omer.
Regarding claim 4, Omer teaches a wireless signal processing method (Omer: Fig. 9, ¶ 21-25, ¶ 30-34, ¶ 104-105; in view of process 900 for filtering channel responses for motion detection) executed by a processing circuit (Omer: Fig. 10, ¶ 21-25, ¶ 30-34, ¶ 116; in view of processor 1010), wherein the wireless signal processing method comprises:
converting a wireless signal which is received by a receiver unit into a frequency-domain signal (Omer: Fig. 5, ¶ 60-61, ¶ 75-77; in view of an observed frequency-domain channel response H.sub.i(f) is received (e.g., at a wireless communication device) over a set of frequencies. The observed frequency-domain channel response H.sub.i(f) may be obtained based on frequency-domain signals included in one or more Legacy PHY fields (e.g., L-LTF, L-STF) of the received wireless signal, or based on frequency-domain signals included in one or more MIMO training fields (e.g., HE-LTF, VHT-LTF, HT-LTF) of the received wireless signal… the received signal R at a wireless communication device can be transformed to the frequency domain, for example, using a Fast Fourier Transform (FFT) or another type of algorithm. Therefore, in order for the wireless communication device to receive wireless signals, it must have a receiver unit configured to receive wireless signals, and as shown in Figure 5, the wireless communication device comprises at least a conversion module that is connected to a receiver unit (i.e., since it receives wireless signals) and can convert wireless signals to frequency-domain signals);
estimating the frequency-domain signal to obtain first channel state information (Omer: ¶ 70-71, ¶ 75-77; wherein the frequency representation H(f) may be referred to as a frequency-domain channel response or the channel state information…each of the wireless signals in the set of wireless signals that is transmitted in the environment may be an orthogonal frequency division multiplexing (OFDM) signal, which can include, for example, a PHY frame… The fields in the PHY frames of the wireless signals in the set of wireless signals can be used to obtain a set of observed frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)}. Each frequency-domain channel response H.sub.i(f) in the set of frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} may correspond to a respective wireless signal in the set of wireless signals. Therefore, observed frequency-domain channel responses are the channel state information that are obtained from wireless signals. As such, if the wireless device is able to estimate CSI from the wireless signals, it may have employed the use of an estimation module that is connected to a conversion module where the wireless signals are received), wherein the first channel state information comprises a plurality of channel state information sub portions (Omer: ¶ 70-71; wherein the frequency representation H(f) may be referred to as a frequency-domain channel response or the channel state information… Each frequency-domain channel response H.sub.i(f) in the set of frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} may correspond to a respective wireless signal in the set of wireless signals. Therefore, the set of frequency-domain channel responses (i.e., CSI) is the first CSI, and it comprises a plurality of CSI sub portions that each correspond to a respective wireless signal in the set of wireless signals); and
filtering the first channel state information to obtain second channel state information (Omer: Fig. 6A – 6B, ¶ 75-79, ¶ 83-84; wherein the system 500 can be used to process each frequency-domain channel response H.sub.i(f) from the set of observed frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} to filter out noise or distortions… the system 500 accepts the set of observed frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} as an input and generates a set of reconstructed frequency-domain channel responses {Ĥ.sub.1(f), Ĥ.sub.2(f), . . . , Ĥ.sub.n(f)} and a set of quality metrics {μ.sub.1, μ.sub.2, . . . , μ.sub.n}… the adaptive constrained solver 504 may impose a constraint 612 on a time duration (e.g., maximum time duration) of the time-domain channel response h.sub.i(t) (as seen in the example of FIG. 6A). Therefore, wireless device comprises a processing unit that is configured to filter the first CSI (i.e., set of frequency-domain channel responses) to obtain a second CSI as shown in Figures 6A and 6B);
wherein the step of obtaining the second channel state information comprises filtering out the channel state information sub portions which are outside a time interval from the first channel state information to obtain the second channel state information (Omer: Fig. 6A – 6B, ¶ 70-72, ¶ 77-85; wherein the adaptive constrained solver 504 executes an iterative constrained least squares optimization process that minimizes an error between the observed frequency-domain channel response H.sub.i(f) and the reconstructed frequency-domain channel response Ĥ.sub.i(f). The adaptive constrained solver 504 generates a filtered time-domain channel response ĥ.sub.i(t) as an output. The adaptive constrained solver 504 may impose one or more constraints in the time-domain…(a constraint 612 on a time duration (e.g., maximum time duration))… pulses that are within the respective constraints 612, 614 are retained, while pulses that are outside of the respective constraints 612, 614 are ignored or discarded… The system 500 includes a time-to-frequency converter block 506 that transforms the filtered time-domain channel response h.sub.i(t) to its corresponding reconstructed frequency-domain channel response Ĥ.sub.i(f). The reconstructed frequency-domain channel response Ĥ.sub.i(f) may represent a filtered version of its corresponding observed frequency-domain channel response H.sub.i(f). Therefore, the processing unit receives the frequency-domain channel responses, converts them to time-domain representation, applies a time-domain boundary/constraint to filter the pulses, then filters the pulses that are within the boundary, transforms the filtered time-domain channel responses to their corresponding reconstructed frequency-domain channel responses to obtain the second CSI as shown in Fig. 6A and 6B).
Regarding claim 6, Omer teaches the wireless signal processing method according to claim 4, wherein the step of obtaining the second channel state information comprises obtaining equivalent frequency-domain information based on time-domain information of the time interval (Omer: ¶ 70-72, ¶ 77-85, ¶ 85-99; wherein the adaptive constrained solver 504 executes an iterative constrained least squares optimization process that minimizes an error between the observed frequency-domain channel response H.sub.i(f) and the reconstructed frequency-domain channel response Ĥ.sub.i(f). The adaptive constrained solver 504 generates a filtered time-domain channel response ĥ.sub.i(t) as an output. The adaptive constrained solver 504 may impose one or more constraints in the time-domain…(a constraint 612 on a time duration (e.g., maximum time duration)) and then filtering out the channel state information sub portions which are outside the time interval from the first channel state information according to the equivalent frequency-domain information (Omer: Fig. 6A – 6B, ¶ 70-72, ¶ 77-85, ¶ 85-99; wherein pulses that are within the respective constraints 612, 614 are retained, while pulses that are outside of the respective constraints 612, 614 are ignored or discarded… The system 500 includes a time-to-frequency converter block 506 that transforms the filtered time-domain channel response h.sub.i(t) to its corresponding reconstructed frequency-domain channel response Ĥ.sub.i(f). The reconstructed frequency-domain channel response Ĥ.sub.i(f) may represent a filtered version of its corresponding observed frequency-domain channel response H.sub.i(f). Therefore, the processing unit receives the frequency-domain channel responses, converts them to time-domain representation, applies a time-domain boundary/constraint to filter the pulses, then filters the pulses that are within the boundary, transforms the filtered time-domain channel responses to their corresponding reconstructed frequency-domain channel responses to obtain the second CSI as shown in Fig. 6A and 6B).
Claim Rejections - 35 USC § 103
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.
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.
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 1 and 3 are rejected under 35 U.S.C. 103 as being unpatentable over Omer et al. [US 20240372749 A1] hereinafter Omer, and further in view of Liu et al. [US 20200178835 A1] hereinafter Liu.
Regarding claim 1, Omer teaches a wireless signal transceiver device (Omer: Fig. 10, ¶ 21-25, ¶ 30-34, ¶ 116; in view of wireless communication devices used for wireless sensing and processing wireless signals) comprising:
a receiver unit configured to receive a wireless signal (Omer: Fig. 5, ¶ 75-77; in view of an observed frequency-domain channel response H.sub.i(f) is received (e.g., at a wireless communication device) over a set of frequencies. The observed frequency-domain channel response H.sub.i(f) may be obtained based on frequency-domain signals included in one or more Legacy PHY fields (e.g., L-LTF, L-STF) of the received wireless signal, or based on frequency-domain signals included in one or more MIMO training fields (e.g., HE-LTF, VHT-LTF, HT-LTF) of the received wireless signal. Therefore, in order for the wireless communication device to receive wireless signals, it must have a receiver unit configured to receive wireless signals);
a conversion module electrically connected to the receiver unit and configured to convert the wireless signal into a frequency-domain signal (Omer: Fig. 5, ¶ 60-61, ¶ 75-77; wherein the received signal R at a wireless communication device can be transformed to the frequency domain, for example, using a Fast Fourier Transform (FFT) or another type of algorithm. Therefore, as shown in Figure 5, the wireless communication device comprises at least a conversion module that is connected to a receiver unit (i.e., since it receives wireless signals) and can convert wireless signals to frequency-domain signals);
an estimation module electrically connected to the conversion module and configured to estimate the frequency-domain signal to obtain first channel state information (Omer: ¶ 70-71, ¶ 75-77; wherein the frequency representation H(f) may be referred to as a frequency-domain channel response or the channel state information…each of the wireless signals in the set of wireless signals that is transmitted in the environment may be an orthogonal frequency division multiplexing (OFDM) signal, which can include, for example, a PHY frame… The fields in the PHY frames of the wireless signals in the set of wireless signals can be used to obtain a set of observed frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)}. Each frequency-domain channel response H.sub.i(f) in the set of frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} may correspond to a respective wireless signal in the set of wireless signals. Therefore, observed frequency-domain channel responses are the channel state information that are obtained from wireless signals. As such, if the wireless device is able to estimate CSI from the wireless signals, it may have employed the use of an estimation module that is connected to a conversion module where the wireless signals are received), wherein the first channel state information comprises a plurality of channel state information sub portions (Omer: ¶ 70-71; wherein the frequency representation H(f) may be referred to as a frequency-domain channel response or the channel state information… Each frequency-domain channel response H.sub.i(f) in the set of frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} may correspond to a respective wireless signal in the set of wireless signals. Therefore, the set of frequency-domain channel responses (i.e., CSI) is the first CSI, and it comprises a plurality of CSI sub portions that each correspond to a respective wireless signal in the set of wireless signals);
a processing unit electrically connected to the estimation module and configured to filter the first channel state information to obtain second channel state information (Omer: Fig. 6A – 6B, ¶ 75-79, ¶ 83-84; wherein the system 500 can be used to process each frequency-domain channel response H.sub.i(f) from the set of observed frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} to filter out noise or distortions… the system 500 accepts the set of observed frequency-domain channel responses {H.sub.1(f), H.sub.2(f), . . . , H.sub.n(f)} as an input and generates a set of reconstructed frequency-domain channel responses {Ĥ.sub.1(f), Ĥ.sub.2(f), . . . , Ĥ.sub.n(f)} and a set of quality metrics {μ.sub.1, μ.sub.2, . . . , μ.sub.n}… the adaptive constrained solver 504 may impose a constraint 612 on a time duration (e.g., maximum time duration) of the time-domain channel response h.sub.i(t) (as seen in the example of FIG. 6A). Therefore, wireless device comprises a processing unit that is configured to filter the first CSI (i.e., set of frequency-domain channel responses) to obtain a second CSI as shown in Figures 6A and 6B); and
wherein the processing unit filters out the channel state information sub portions which are outside a time interval from the first channel state information to obtain the second channel state information (Omer: Fig. 6A – 6B, ¶ 70-72, ¶ 77-85; wherein the adaptive constrained solver 504 executes an iterative constrained least squares optimization process that minimizes an error between the observed frequency-domain channel response H.sub.i(f) and the reconstructed frequency-domain channel response Ĥ.sub.i(f). The adaptive constrained solver 504 generates a filtered time-domain channel response ĥ.sub.i(t) as an output. The adaptive constrained solver 504 may impose one or more constraints in the time-domain…(a constraint 612 on a time duration (e.g., maximum time duration))… pulses that are within the respective constraints 612, 614 are retained, while pulses that are outside of the respective constraints 612, 614 are ignored or discarded… The system 500 includes a time-to-frequency converter block 506 that transforms the filtered time-domain channel response h.sub.i(t) to its corresponding reconstructed frequency-domain channel response Ĥ.sub.i(f). The reconstructed frequency-domain channel response Ĥ.sub.i(f) may represent a filtered version of its corresponding observed frequency-domain channel response H.sub.i(f). Therefore, the processing unit receives the frequency-domain channel responses, converts them to time-domain representation, applies a time-domain boundary/constraint to filter the pulses, then filters the pulses that are within the boundary, transforms the filtered time-domain channel responses to their corresponding reconstructed frequency-domain channel responses to obtain the second CSI as shown in Fig. 6A and 6B).
Although Omer discloses having a processor 1010 and a memory 1020 in the wireless communication device, Omer does not explicitly disclose a storage unit electrically connected to the processing unit and configured to store the second channel state information.
Referring to the invention of Liu, Liu teaches a storage unit electrically connected to the processing unit and configured to store the channel state information (Liu: Fig. 8, ¶ 13, ¶ 52; wherein a device for measuring physiological state information based on channel state information is provided. The device comprises one or more processors and one or more computer storage media for storing one or more computer-readable instructions. The processor is configured to drive the computer storage media to execute the following tasks: receiving channel state information (CSI)).
Thus, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the claimed invention to modify the filtering channel responses for motion detection teachings of Omer with the storing of CSI in the CSI based measurement of physiological state information teachings of Liu in order to improve throughput, reliability, latency, and efficiency in wireless systems.
In view of Liu teaching the processing and storage of CSI, when combined with the teachings of Omer, a person having ordinary skills in the art will find that the limitation “a storage unit electrically connected to the processing unit and configured to store the second channel state information” will obviously be met.
Regarding claim 3, Omer in view of Liu teaches the wireless signal transceiver device according to claim 1, wherein the processing unit obtains equivalent frequency-domain information based on time-domain information of the time interval (Omer: ¶ 70-72, ¶ 77-85, ¶ 85-99; wherein the adaptive constrained solver 504 executes an iterative constrained least squares optimization process that minimizes an error between the observed frequency-domain channel response H.sub.i(f) and the reconstructed frequency-domain channel response Ĥ.sub.i(f). The adaptive constrained solver 504 generates a filtered time-domain channel response ĥ.sub.i(t) as an output. The adaptive constrained solver 504 may impose one or more constraints in the time-domain…(a constraint 612 on a time duration (e.g., maximum time duration)) and then filters out the channel state information sub portions which are outside the time interval from the first channel state information according to the equivalent frequency-domain information (Omer: Fig. 6A – 6B, ¶ 70-72, ¶ 77-85, ¶ 85-99; wherein pulses that are within the respective constraints 612, 614 are retained, while pulses that are outside of the respective constraints 612, 614 are ignored or discarded… The system 500 includes a time-to-frequency converter block 506 that transforms the filtered time-domain channel response h.sub.i(t) to its corresponding reconstructed frequency-domain channel response Ĥ.sub.i(f). The reconstructed frequency-domain channel response Ĥ.sub.i(f) may represent a filtered version of its corresponding observed frequency-domain channel response H.sub.i(f). Therefore, the processing unit receives the frequency-domain channel responses, converts them to time-domain representation, applies a time-domain boundary/constraint to filter the pulses, then filters the pulses that are within the boundary, transforms the filtered time-domain channel responses to their corresponding reconstructed frequency-domain channel responses to obtain the second CSI as shown in Fig. 6A and 6B).
