Regarding claim 1 Tarighat discloses: A method of supporting a wireless transmission from a transmitter device via a coverage enhancing device to a receiver device (Para 0021: “Certain embodiments of the disclosure may be found in a repeater system and method for high-performance communication, for example, data communication. The repeater system and method of the present disclosure not only improves data transfer rates between at least two network nodes as compared to existing wireless communication systems (e.g. a cellular network or other wireless networks), but also enables almost near zero latency communication and an always-connected experience. The repeater system may deploy a plurality of repeater devices, which may be configured to perform distributed multiple-input multiple-output (MIMO) operations, and enhance the wireless communication capacity, coverage, and reliability between a source network node and a destination network node, for high-performance communication. In the following description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown, by way of illustration, various embodiments of the present disclosure.”), the coverage enhancing device being reconfigurable to provide multiple spatial filters by applying, at multiple antenna elements, one or more phase shifts to electromagnetic waves of signals of the wireless transmission (Para 0040: “ In some embodiments, the receiving antenna array (e.g. the first receiving antenna array 104A or the second receiving antenna array 106A) and transmitting antenna array (e.g. the first transmitting antenna array 1048 or the second transmitting antenna array 1068) inside a repeater device (e.g. the first repeater device 104 or the second repeater device 106) operate at the same carrier RF frequency. In this case, no frequency shift is applied/observed between the incoming signal compared to the outgoing signal. In some embodiments, the carrier RF frequency of incoming and outgoing signals may be different. This embodiment may be utilized, for 1) better utilization of spectral channels, 2) better overall frequency planning in network, 3) better isolation between the two antenna arrays inside the repeater device operating at same time/channel. In some embodiments, the antenna arrays in a repeater device of the repeater system 102 may deploy classic phase shifters per antenna element to create configurable or programmable antenna radiation patterns. In some embodiments, the antenna arrays may be implemented by other means of creating programmable phase shifts in RF signals per group of radiating elements of a given antenna array. In some embodiments, digital domain computations (e.g. complex multipliers (certain amplitude and certain phase of a signal) or true delay line implementations per radiating element may be deployed to produce directional and/or configurable radiation patterns.”), each one of the multiple antenna elements of the coverage enhancing device being associated with a respective one of two orthogonal polarization components of a polarization of the electromagnetic waves (Para 0055: “In accordance with an embodiment, one or more implementations may be jointly or separately supported by the communication system 300. For example, in a first implementation, all beams and data streams (e.g. streams S11, S12, S21, and S22 carried by different beams of RF signals) shown in the FIG. 3, may be transported over the same antenna radiation polarity (e.g. all transmitted over vertical polarization, or all transmitted over horizontal, or all transmitted over circular polarization). In a second implementation, a subset of beams (and streams) shown in the FIG. 3, may be transported over H polarization, while another subset may be transported over V polarization. Additionally, in some embodiments, the subset of beams in a certain polarization may differ between nodes (i.e. the source network node 308 and the destination network node 310) and the repeater devices 304 and 306. This enables additional configurability, where a stream may be transmitted on a certain polarization type, while being re-transmitted by a repeater device (e.g. the repeater devices 304 or the repeater device 306) of the repeater system 302 on a different polarization type.”), wherein the method comprises: configuring the coverage enhancing device to activate at least one predefined spatial filter of the multiple spatial filters (Para 0041: “In accordance with an embodiment, the repeater system 102 may be configured to perform beam pattern configuration. Each antenna array (either transmitting or receiving) within a repeater device (e.g. the first repeater device 104 or the second repeater device 106) may be further configured to select and form a radiation pattern from a plurality of possible beam patterns. In the case of concurrent multi-beam mode of operation, each beam can be configured independently. Several approach may be used for selecting the beam configurations for various links in/out of each repeater device of the repeater system 102. In a first approach, a localized beam configuration selection may be employed, in which a repeater device (e.g. the first repeater device 104 or the second repeater device 106) may implement operations self-contained within the repeater device to determine what beam configurations to use. For example, the first repeater device 104 may be configured to measure SNR or received signal power to select the best beam configuration when receiving a signal from the source device, such as the first network node 108.”), and upon configuring the coverage enhancing device to activate the at least one predefined spatial filter, configuring the transmitter device to transmit the signals using a circular polarization of the electromagnetic waves (Para 0055: “In accordance with an embodiment, one or more implementations may be jointly or separately supported by the communication system 300. For example, in a first implementation, all beams and data streams (e.g. streams S11, S12, S21, and S22 carried by different beams of RF signals) shown in the FIG. 3, may be transported over the same antenna radiation polarity (e.g. all transmitted over vertical polarization, or all transmitted over horizontal, or all transmitted over circular polarization). In a second implementation, a subset of beams (and streams) shown in the FIG. 3, may be transported over H polarization, while another subset may be transported over V polarization. Additionally, in some embodiments, the subset of beams in a certain polarization may differ between nodes (i.e. the source network node 308 and the destination network node 310) and the repeater devices 304 and 306. This enables additional configurability, where a stream may be transmitted on a certain polarization type, while being re-transmitted by a repeater device (e.g. the repeater devices 304 or the repeater device 306) of the repeater system 302 on a different polarization type.”).

In the case of concurrent multi-beam mode of operation, each beam can be configured independently. Several approach may be used for selecting the beam configurations for various links in/out of each repeater device of the repeater system 102.

In a first approach (a), such plurality of signal parameters (e.g. complex value parameters of gain/phase) may use the expression: a.sub.11*exp(j*phi.sub.11). Each repeater device (such as repeater devices 304 and 306) may include different values for these signal parameters. In some embodiments, 8 total complex coefficients (4 coefficients per repeater device in the repeater system 302, in this example), may be derived and selected to: 1) optimize MIMO capacity of the MIMO channel from [S11 S12; S21 S22] to [R11 R12; R21 R22].

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.
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.

Claim 6 is rejected under 35 U.S.C 103 as being unpatentable over Tarighat (US20200358518A1) in view of Bengeult (CN1223195C).
Regarding claim 6 Tarighat discloses all the limitations of claim 1. Tarighat does not “wherein the at least one predefined spatial filter is associated with not operating the coverage enhancing device in a closed-loop beam tracking mode “.
However, Bengeult in the analogous arts teaches: wherein the at least one predefined spatial filter is associated with not operating the coverage enhancing device in a closed-loop beam tracking mode (Description: “receiving antenna 82 may implement a closed-loop tracking system, to align the antenna beam or based on the amplitude of the received signal to adjust polarization of the antenna. the transmitting antenna 74 to the receiving antenna 82 pointing and polarization. the other one can be chosen executive plan is using an open-loop tracking method, IRU (Inertial Reference Unit, inertial reference unit with the on-board) the method and according to the position and height of the mobile platform and the satellite 18 position to determine the pointing and polarization antenna.”).
It would have been obvious to someone in the art prior to the effective filing date of the claimed invention to modify Tarighat with Bengeult to incorporate the feature of: wherein the at least one predefined spatial filter is associated with not operating the coverage enhancing device in a closed-loop beam tracking mode. Tarighat and Bengeult are all considered analogous arts as they all disclose methods for enhancing signals in communication networks. However, Tarighat fails to disclose a feature of sending and receiving a capability message. This feature is disclosed by Bengeult. It would have been obvious to someone in the art prior to the effective filling date of the claimed invention to modify Tarighat with Bengeult to incorporate the feature of: wherein the at least one predefined spatial filter is associated with not operating the coverage enhancing device in a closed-loop beam tracking mode as such a feature would increase the efficiency of the system.
Claim 9 is rejected under 35 U.S.C 103 as being unpatentable over Tarighat (US20200358518A1) in view of Raghavan (US20210351830).
Regarding claim 9 Tarighat discloses all the limitations of claim 1. Tarighat does not teach “obtaining, from the coverage enhancing device and on a control link, a capability message indicative of a capability of the coverage enhancing device to activate the at least one predefined spatial filter “.
However, Raghavan in the analogous arts teaches: obtaining, from the coverage enhancing device and on a control link, a capability message indicative of a capability of the coverage enhancing device to activate the at least one predefined spatial filter (Para 0030: “After determining (e.g., identifying) the subset of antenna elements, the UE transmits to the network entity a message that indicates that the subset of antenna elements is to be used to communicate in the second communication direction. In some implementations, indication of the subset of antenna elements is included in the message. Alternatively, the message may indicate that a different antenna array is used in the second communication direction than in the first communication direction, and the message may not indicate a lack of beam correspondence between the first communication direction and the second communication direction, or may indicate a mixed-mode beam correspondence between the first communication direction and the second communication direction. For example, the message may include a multi-bit field, such as a UE capability field, that indicates a state that is different than a state corresponding to a lack of beam correspondence (e.g., no beam correspondence) and a state that corresponds to beam correspondence (e.g., full beam correspondence).”).
It would have been obvious to someone in the art prior to the effective filing date of the claimed invention to modify Tarighat with Raghavan to incorporate the feature of: obtaining, from the coverage enhancing device and on a control link, a capability message indicative of a capability of the coverage enhancing device to activate the at least one predefined spatial filter. Tarighat and Raghavan are all considered analogous arts as they all disclose methods for enhancing signals in communication networks. However, Tarighat fails to disclose a feature of sending and receiving a capability message. This feature is disclosed by Raghavan. It would have been obvious to someone in the art prior to the effective filling date of the claimed invention to modify Tarighat with Raghavan to incorporate the feature of: obtaining, from the coverage enhancing device and on a control link, a capability message indicative of a capability of the coverage enhancing device to activate the at least one predefined spatial filter as such a feature would increase the efficiency of the system.
