This office action is in response to remarks filed on 11/07/2025. Claims 1-5, 9-15 and 19-20 are pending and presented for examination. Claims 1, 2, 9, 10 and 14 are amended. Claims 6-8 and 16-18 are cancelled. Response to Amendments Claims 1, 2, 9, 10 and 14 have been considered based on amendments. Objections to claims 2 and 10 are withdrawn based on amendments to these claims. 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 non-obviousness. 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 1-5, 9-15 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over De Carvalho (WO2016070122A1) (hereinafter "De Carvalho") in view of Wu et al (US20210337416A1) (hereinafter "Wu").

At the beginning of each time slot, a training period may be divided into slots that are alternatively dedicated to direct and reverse transmission.) element to a first terminal device (Pg. 17, ln 22-23: Device A is base station and the at least one second device, for example, Device B, is at least one user.); receiving, by the network device, a fourth signal (Pg. 12, Ln. 1-2: Weight vector ( PNG media_image2.png 26 29 media_image2.png Greyscale ) may be employed to transmit a training sequence from Device B to Device A.) on a second resource element, wherein the second resource element and the first resource element at least partially overlap or are adjacent to each other (Pg. 13, Ln. 7-10: one time slot may contain a training period followed by uplink and downlink data transmission. At the beginning of each time slot, a training period may be divided into slots that are alternatively dedicated to direct and reverse transmission.); sending, by the network device, downlink data (Pg. 13, Ln. 7-10: one time slot may contain a training period followed by uplink and downlink data transmission.) by using a first beamforming (BF) weight (Pg. 12, Ln. 10-13: Device A may take the complex conjugate of ( PNG media_image3.png 20 32 media_image3.png Greyscale ) and obtain ( PNG media_image4.png 21 25 media_image4.png Greyscale ). Device A may normalize ( PNG media_image5.png 22 22 media_image5.png Greyscale ) so that when the normalized version of ( PNG media_image4.png 21 25 media_image4.png Greyscale ) is employed as transmit beamforming weights, the transmit power constraint of the communication system is satisfied.), wherein the first BF weight is obtained based on signal processing performed on the fourth signal (Pg. 3, Ln. 12-15: an iterative procedure relying on ping-pong transmissions between two antenna arrays, where, at each iteration, a device simply returns the conjugate of the signal that it was just served. Ping-Pong Beamforming (PPB) converges to the optimal beamforming weights at each communication end), and an operation amount of the signal processing is less than an operation amount of matrix inversion or matrix decomposition (Pg. 5, Ln. 2-4: the application of PPB appears as a reasonable low complexity alternative to find the channel eigenvectors rather than direct channel estimation followed by a singular value decomposition.); De Carvalho fails to disclose a communication method, comprising: receiving, by the network device, a first request message, wherein the first request message instructs the network device to determine a position of the first resource element; and sending, by the network device, first indication information, wherein the first indication information indicates the position of the first resource element or a position of the second resource element. However, Wu discloses a communication method, comprising: receiving, by the network device, a first request message, wherein the first request message instructs the network device to determine a position of the first resource element; and ([0099] The UE may send the report information to the base station by using an uplink channel such as a physical uplink control channel (PUCCH), a scheduling request (SR), or a physical random access channel (PRACH) … The resource element set may be in a unit of a resource block (RB), or may be in a unit of a sub-RB. A base station may determine, based on a time-frequency position at which the report information is received and additional orthogonal code (for example, orthogonal preamble code, to further increase a maximum quantity of UEs that support simultaneous sending of the report information), UE from which the report information is received.) sending, by the network device, first indication information, wherein the first indication information indicates the position of the first resource element or a position of the second resource element ([0074] Step 302: The UE receives feedback information from the base station, where the feedback information includes sending status information of the one or more downlink reference signals.

When receiving the feedback information after the resource 3, the UE updates N310.). De Carvalho and Wu are considered to be analogous to the claimed invention because both are in the same endeavor of ascertaining the position of a resource element. 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 a motivation to combine the teachings of De Carvalho and Wu to create a communication method, comprising: receiving, by the network device, a first request message, wherein the first request message instructs the network device to determine a position of the first resource element; and sending, by the network device, first indication information, wherein the first indication information indicates the position of the first resource element or a position of the second resource element.

Regarding claim 20, De Carvalho discloses the first terminal device, wherein the operations further comprise: receiving second indication information instructing the first terminal device to receive the second signal and/or obtain the third signal (Pg. 39, Ln. 10-13: perform the ping-pong beamforming process using a first transmission protocol to exchange messages with the second device, the first transmission protocol comprises a plurality of time slots with individual time slots being dedicated to one transmission direction and having a training period followed by a data period). Response to Arguments On page 8 of the Applicant's remarks, the Applicant states, " The Applicant respectfully requests confirmation of the Applicant's claim for foreign priority as well as the Office's receipt of all certified copies of referenced priority documents." This application is a continuation of PCT CN2021/070605; it does not claim any priority to a foreign application. Please see Application Data Sheet filed on 07/06/2023. Applicant's arguments filed 11/07/2025 have been fully considered but they are not persuasive. On page 11 of Applicant's remarks, Applicant states, "As detailed above, De Carvalho does not disclose the network device receives a first request message prior to sending a first signal/training sequence, wherein the first request message instructs the network device to determine a position of the first resource element. Moreover, De Carvalho does not disclose the network device sends first indication information indicating the position of the first resource element or a position of the second resource element. In view of these deficiencies, it is clear that De Carvalho does not anticipate claim 1 as amended herein. Accordingly, the Applicant requests withdrawal of the 35 U.S.C. § 102 rejection of claim 1." Examiner respectfully disagrees, noting that Wu [0099] discloses the base station determining a resource element based on the time-frequency position on which it receives a report information from a UE, and [0074] the UE receiving feedback information from the base station. The examiner thus maintains the rejection of claim 1 based on 35 USC 103. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
