Response to Remarks
This Office action is considered fully responsive to the amendments filed 11/12/2025. Claims 1-20 are pending in the application. Claims 1-20 were previously presented.
Response to Arguments
Applicant's arguments filed on 10/30/2025 have been fully considered but they are not persuasive. Applicant argues in substance that:
The office action fails to teach of one or more processors configured to generate a first frame requesting a second device in a wireless local area network (WLAN) to perform channel sounding with the first device using the determined frequency of channel sounding; and wirelessly transmit, via a transceiver, the generated first frame to the second device (Page 6 and 8, Remarks).
The examiner respectfully disagrees. Chun explicitly discloses in Figs. 1 and 2A and [0024], the apparatus 102 may include a mobility processor 110, a sounding transceiver 120, a sounding-control circuit 130, a mobility-calculating circuit 140, and a receiver 150. In [0189], lines 1-3, and [0187] state “In a wireless LAN system, a sounding procedure/protocol is used to determine channel state information. A beamformer STA requesting channel state information may transmit a training signal to beamformee STA(s). The beamformee STA may measure a channel using the training signal (e.g., sounding NDP) and feedback an estimate of a channel state to the beamformer STA.” and Claim 12 and [0283], confirm that the transmitted NPD frame can includes information about the determined frequency of channel sounding, [0215], [0273]. Fig. 1, abstract, [0045], and [0178], illustrate both devises are wirelessly connected through transceivers to perform a transmission and reception operation of a signal “one of the STAs 100 and 200 may perform an intended operation of an AP, and the other of the STAs 100 and 200 may perform an intended operation of a non-AP STA. For example, the transceivers 106 and 206 of FIG. 1 may perform a transmission and reception operation of a signal (e.g., a packet or a physical layer protocol data unit (PPDU) conforming to IEEE 802.11a/b/g/n/ac/ax/be).” Therefore, Chun still teaches the limitations as currently claimed.
Chun do not teach the claimed "channel sounding with the first device using the determined frequency of channel sounding"(Page 8, Remarks).
The examiner respectfully disagrees. Chun explicitly state in claim 1 “receiving a null data PPDU (NDP) announcement frame from a second STA on a first frequency unit related to a first type physical layer protocol data unit (PPDU) format and a second frequency unit related to a second type PPDU format; and transmitting a feedback frame related to one or more of the first frequency unit or the second frequency unit to the second STA” and [0008], “A method for performing a sounding procedure by a first station (STA) in a WLAN system according to an aspect of the present disclosure may comprise, receiving a null data PPDU (NDP) announcement frame from a second STA on a first frequency unit related to a first type physical layer protocol data unit (PPDU) format and a second frequency unit related to a second type PPDU format; and transmitting a feedback frame related to one or more of the first frequency unit or the second frequency unit to the second STA.” That’s implies the sounding procedure is performed based on these determined frequency units and the feedback is sent according to that. Therefore, Chun still teaches the limitations as currently claimed.
Applicant argues that similar independent claims are allowable for similar reasons (Page 9, Remarks).
The examiner respectfully disagrees, for at least the same reasons given in the response above, and as detailed in the Claim Rejections section below.
Applicant argues that dependent claim/new claims are allowable due to dependencies from allegedly allowable independent claims (Page 9, Remarks).
The examiner respectfully disagrees, at least for the same reason given in the response above and as detailed in the Claim Rejections section below.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
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, 2, 9, 11, 12, 19 are rejected under 35 U.S.C. 103 as being unpatentable over Yu et al. (US-20220400033-A1) in view of Chun et al. (US-20240235718-A9).
Regarding claim 1 (Original), Yu teaches a first device comprising: one or more processors ( Figs. 1 and 2A and [0024], describe the apparatus 102 may include a mobility processor 110, a sounding transceiver 120, a sounding-control circuit 130, a mobility-calculating circuit 140, and a receiver 150) configured to: determine a frequency of channel sounding based at least on a movement characteristic of the first device (abstract, Fig.2B, [0058], lines 4-8, and [0025], lines 7-10, describe the frequency of channel sounding, refers as rate at which channel sounding occurs (how many times the sounding process is performed in the unite of time as shown in the Fig. 2B), can be determined by sounding interval, which can be adjusted according to the mobility (movement characteristics) of the device. The mobility is configured by Link quality LQ as shown in Fig. 3B); and
Yu fails to teach generate a first frame requesting a second device in a wireless local area network (WLAN) to perform channel sounding with the first device using the determined frequency of channel sounding; and wirelessly transmit, via a transceiver, the generated first frame to the second device.
However, Chun teaches generate a first frame requesting a second device in a wireless local area network (WLAN) to perform channel sounding with the first device using the determined frequency of channel sounding and wirelessly transmit, via a transceiver, the generated first frame to the second device ([0189], lines 1-3, and [0187] “In a wireless LAN system, a sounding procedure/protocol is used to determine channel state information. A beamformer STA requesting channel state information may transmit a training signal to beamformee STA(s). The beamformee STA may measure a channel using the training signal (e.g., sounding NDP) and feedback an estimate of a channel state to the beamformer STA.” and Claim 12 and [0283], confirm that the transmitted NPD frame can includes information about the determined frequency of channel sounding, [0215], [0273]. Fig. 1, abstract, [0045], and [0178], illustrate both devises are wirelessly connected through transceivers to perform a transmission and reception operation of a signal “one of the STAs 100 and 200 may perform an intended operation of an AP, and the other of the STAs 100 and 200 may perform an intended operation of a non-AP STA. For example, the transceivers 106 and 206 of FIG. 1 may perform a transmission and reception operation of a signal (e.g., a packet or a physical layer protocol data unit (PPDU) conforming to IEEE 802.11a/b/g/n/ac/ax/be).”
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu to incorporate the teachings of Chun (in analogous art) by adding generate a first frame requesting a second device in WLAN to perform channel sounding with the first device using the determined frequency of channel sounding for efficient utilization of multiple bands and increased spatial streams, in particular, to support low latency or real-time traffic (Chun, [0004], lines 6-9).
Regarding claim 2 (Original), Yu and Chun teach the first device according to claim 1.
Chun further teaches wherein one of the first device or the second device is an access point ([0035], lines 8-11 and [0036], lines 6-14, the device 110 and 200 may perform an access point (AP) or a non-AP. When the STAs 110 and 200 perform an AP function, they may be simply referred to as APs, and when the STAs 110 and 200 perform non-AP functions).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu to incorporate the teachings of Chun (in analogous art) by adding one of the first device or the second device is an access point for efficient data transmission and avoiding collisions (Chun, [0054], lines 3-5).
Regarding claim 9 (Original), Yu and Chun teach the first device according to claim 1.

Regarding claim 11 (Original), Yu teaches the method comprising: determining, by a first device, a frequency of channel sounding based at least on a movement characteristic of the first device; (abstract, Fig.2B, [0058], lines 4-8, and [0025], lines 7-10, describe the frequency of channel sounding, refers as rate at which channel sounding occurs (how many times the sounding process is performed in the unite of time as shown in the Fig. 2B), can be determined by sounding interval, which can be adjusted according to the mobility (movement characteristics) of the device. The mobility is configured by Link quality LQ as shown in Fig. 3B).
Yu fails to teach generating, by the first device, a first frame requesting a second device in a wireless local area network (WLAN) to perform channel sounding with the first device using the determined frequency of channel sounding.
However, Chun teaches generating, by the first device, a first frame requesting a second device in a wireless local area network (WLAN) to perform channel sounding with the first device using the determined frequency of channel sounding and wirelessly transmitting, via a transceiver, the generated first frame to the second device ([0189], lines 1-3, and [0187] “In a wireless LAN system, a sounding procedure/protocol is used to determine channel state information. A beamformer STA requesting channel state information may transmit a training signal to beamformee STA(s). The beamformee STA may measure a channel using the training signal (e.g., sounding NDP) and feedback an estimate of a channel state to the beamformer STA.” and Claim 12 and [0283], confirm that the transmitted NPD frame can includes information about the determined frequency of channel sounding, [0215], [0273]. Fig. 1, abstract, [0045], and [0178], illustrate both devises are wirelessly connected through transceivers to perform a transmission and reception operation of a signal “one of the STAs 100 and 200 may perform an intended operation of an AP, and the other of the STAs 100 and 200 may perform an intended operation of a non-AP STA. For example, the transceivers 106 and 206 of FIG. 1 may perform a transmission and reception operation of a signal (e.g., a packet or a physical layer protocol data unit (PPDU) conforming to IEEE 802.11a/b/g/n/ac/ax/be).”);
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu to incorporate the teachings of Chun (in analogous art) by adding generate a first frame requesting a second device in WLAN to perform channel sounding with the first device using the determined frequency of channel sounding for efficient utilization of multiple bands and increased spatial streams, in particular, to support low latency or real-time traffic (Chun, [0004], lines 6-9).

When the STAs 110 and 200 perform an AP function, they may be simply referred to as APs, and when the STAs 110 and 200 perform non-AP functions).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu to incorporate the teachings of Chun (in analogous art) by adding one of the first device or the second device is an access point for efficient data transmission and avoiding collisions (Chun, [0054], lines 3-5).
Regarding claim 19 (Original), Yu and Chun teach the method according to claim 11.
Chun further teaches wherein the first frame is one of an association request frame, an association response frame, a probe request frame, or a probe response frame ([0078], lines 9-12, The association process includes a process in which the device transmits an association request frame to the AP, and in response, the AP transmits an association response frame to the STA).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu to incorporate the teachings of Chun (in analogous art) by adding the first frame can be one of an association request frame, an association response frame, a probe request frame, or a probe response frame for efficient utilization of multiple bands and increased spatial streams, in particular, to support low latency or real-time traffic (Chun, [0004], lines 6-9).

Regarding claim 3 (Original), Yu and Chun teach the first device according to claim 1.
Yu and Chun do not explicitly teach set a field of the first frame to a first value indicating one or more velocities of the first device, to request the second device to perform channel sounding with the first device periodically according to the one or more velocities.

[0057] implies higher mobility or faster changes in the channel stat. In such a case the system uses a short period (first period) for channel sounding compared to the longer period (second period).

Yu further teaches setting the field of the first frame to a second value different from the first value ([0057] as described in claim 4, if the first and second values of velocities are different (e.g., the first velocity greater than the second velocity), then the mobility process may control the sounding transceiver to perform a the sounding operation immediately to accommodate the rapid changes caused by higher mobility, thereby improving the communication reliability and performance), to request the second device to perform channel sounding with the first device ([0026], lines 8-11, describes the case where the first device sends triggering sounding to request the sounding report packet by performing channel sounding) and subsequently send a beamformed frame to the first device ([0005], lines 6-14, and [0047], lines 1-4, After performing channel sounding and obtaining updated channel state information (CSI) or Beamforming feedback information stream, which is then fed back to the transmitter (first device) as a stream (frame) [0005], lines 1-5).

beamformee sounding profile.
However, Jeon teaches the first frame is a frame having a type of an action frame ([0106], referring to FIG. 15, the feedback frame may include a category field and an EHT action field (or simply an action field) and the first frame comprises a field of extremely high throughput (EHT) action indicating beamformee sounding profile (Figs. 15, 17 and 18, [0105]-[0107] describe the feedback frame includes a field of sounding profile through EHT action field, which include information about the beamformee sounding record as it specifies the type of feedback being provided such as compressed beamforming, CQI, sounding token number and other parameters related to the beamformee’s channel state).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu and Chun to incorporate the teachings of Jeon (in analogous art) by including the field of extremely high throughput (EHT) action indicating compressed beamforming (CB)/channel quality indication (CQI) to adapt different to support high throughput and low-latency communication (Jeon, [0005]).
Regarding claim 18 (Original), Yu and Chun teach the method according to claim 11.
Yu and Chun do not explicitly teach wherein the first frame is a frame having a type of an action frame, and the first frame comprises a field of extremely high throughput (EHT) action indicating compressed beamforming (CB)/channel quality indication (CQI).
However, Jeon teaches the first frame is a frame having a type of an action frame ([0106], referring to FIG. 15, the feedback frame may include a category field and an EHT action field (or simply an action field) and the first frame comprises a field of extremely high throughput (EHT) action indicating compressed beamforming (CB)/channel quality indication (CQI) (Fig. 17, [0110], lines 4-7, indicating an EHT, the action field may have a value (e.g., 0) corresponding to an EHT compressed beamforming/CQI frame or a value (e.g., 1) corresponding to an uplink compressed beamforming frame as shown in Fig. 17).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Yu and Chun to incorporate the teachings of Jeon (in analogous art) by including the field of extremely high throughput (EHT) action indicating compressed beamforming (CB)/channel quality indication (CQI) to adapt different to support high throughput and low-latency communication (Jeon, [0005]).
Regarding claim 20 (Original), Yu and Chun teach the method according to claim 11.
Yu and Chun do not explicitly teach the first frame is a frame having a type of an action frame, and the first frame comprises a field of extremely high throughput (EHT) action indicating
beamformee sounding profile.
However, Jeon teaches the first frame is a frame having a type of an action frame ([0106], referring to FIG. 15, the feedback frame may include a category field and an EHT action field (or simply an action field) and the first frame comprises a field of extremely high throughput (EHT) action indicating beamformee sounding profile (Figs. 15, 17 and 18, [0105]-[0107] describe the feedback frame includes a field of sounding profile through EHT action field, which include information about the beamformee sounding record as it specifies the type of feedback being provided such as compressed beamforming, CQI, sounding token number and other parameters related to the beamformee’s channel state).
