DETAILED ACTION
Notice of Pre-AIA  or AIA  Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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.
Claims 32-33, 36-38, 40, and 50-53 are rejected under 35 U.S.C. 103 as being unpatentable over Bayesteh (US Pat Pub# 2021/0302561) and further in view of Kumar et al. (US Pat Pub# 2020/0145977).
Regarding claims 32 and 40, Bayesteh teaches an apparatus, comprising at least one processor 200 (Fig. 2A); and at least one non-transitory memory 208 (Fig. 2A) storing instructions that, when executed with the at least one processor, cause the apparatus to perform sending, with a network node in a wireless network, a reconfigurable reflecting surface for adjusting elements of the reconfigurable reflecting surface for one or more positioning reference signal transmissions from a base station toward a user equipment (Sections 0043-0045 and 0077, adjustable /reconfigurable intelligent surface panels to provide position signals to the user equipment etc.); receiving, with the network node, one or more measurements taken with the user equipment for the one or more positioning reference signal transmissions, wherein the one or more positioning reference signal transmissions have a direct path between the base station and the user equipment and a reflection path that reflects off the reconfigurable reflecting surface (Section 0077, measuring signals directly from a base station and reflected beams via an RIS); and calculating, with the network node, a position coordinate corresponding to the user equipment using the one or more measurements with knowledge of a location of the reconfigurable reflecting surface (Section 0077, network making the calculation to find a location of the electronic device etc.).  Bayesteh fails to teach a request.
Kumar teaches an apparatus, comprising cause the apparatus to perform sending, with a network node in a wireless network, a request of one or more settings for one or more positioning reference signal transmissions from a base station toward a user equipment (Sections 0051, 0058, and 0071-0072, requesting location estimating etc.).
Therefore, it would have been obvious at the time of the invention to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate a request as taught by Kumar into Bayesteh apparatus in order to improve location finding communication.
Regarding claim 36, the combination including Bayesteh teaches wherein the calculating further comprises the network node performing a procedure for separating components from the direct path and the reflected path in the one or more measurement results provided by the user equipment (Section 0077, network making the calculation to find a location of the electronic device etc.).
Regarding claim 37, the combination including Bayesteh teaches wherein the calculating further comprises the network node performing a procedure for information from the direct path and the reflected path in the one or more measurement results provided by the user equipment (Section 0077, network making the calculation to find a location of the electronic device etc.).
Kumar teaches the network node performing a procedure for extracting channel state information from the direct path (Section 0085, CSI measurements etc.).
Regarding claim 38, the combination including Kumar further teaches wherein the network node comprises a location management function 152 (Fig. 1B) that performs at least the calculating, wherein the network node is one of separate from the base station or is the base station (Fig. 1B and Sections 0065-0066 and 0070, location management function).
Regarding claim 50, the combination including Bayesteh teaches the base station sending the indication of the one or more measurements toward a network node for use with the network node to calculate a position coordinate corresponding to the user equipment using the one or more measurements with knowledge of a location of the reconfigurable reflecting surface, wherein indication of the one or more measurements comprises an indication of whether corresponding measurements are time of arrival, angle of arrival, or reference signal received power measurements (Sections 0129-0131, time of arrival measurement etc.).
Regarding claim 51, the combination including Bayesteh teaches the base station calculating a position coordinate corresponding to the user equipment using the one or more measurements with knowledge of a location of the reconfigurable reflecting surface (Section 0077, network making the calculation to find a location of the electronic device etc.).
Regarding claim 52, claim 52 is rejected for the same reasons as claims 32 and 40.  Further Bayesteh teaches it is obvious of a second configuration to cause the user equipment to perform one or more measurements for the one or more positioning reference signal transmissions (Sections 0077, as stated the electronic device able to do measurements of the received signals etc.).
Regarding claim 53, the combination including Bayesteh teaches resolving a
reflector path signal for the reflection path with using the configuration useable with the reconfigurable reflecting surface (Abstract and Sections 0008-0014, 0043-0045, and 0077, reflector path with the reconfigurable reflecting surface etc.).
Claims 47 and 49 are rejected under 35 U.S.C. 103 as being unpatentable over Bayesteh (US Pat Pub# 2021/0302561) and further in view of Kumar et al. (US Pat Pub# 2020/0145977) and further in view of Sun et al. (US Pat Pub# 2021/0377932).
Regarding claim 47, Bayesteh in view of Kumar teaches the limitations in claim 40.  Bayesteh and Kumar fails to teach a control channel.
Sun teaches sending, with the base station sending; via one or more of a wireless control channel, a wired control channel, or a dedicated channel, one or more setting parameters for adjusting the elements of the reconfigurable reflecting surface (Sections 0007 and 0071 and Claim 30, control and dedicated channels etc.).
Therefore, it would have been obvious at the time of the invention to one of ordinary skill in the art before the effective filing date of the claimed invention to incorporate a control channel as taught by Sun into a request as taught by Kumar into Bayesteh apparatus in order to improve communication.
Regarding claim 49, Sun further teaches wherein the base station connects, using a positioning protocol, to the reconfigurable reflecting surface through radio resource control for a static control of the setting parameters, or through downlink control information for dynamic control of the setting parameters, or through a wired link for one or both of static or dynamic control of the setting parameters (Section 0071 and Claim 30, downlink control channel etc.).
Allowable Subject Matter
Claims 33, 39, 41-44, 48, and 54-55 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
