In regard to Claim 1, Yang teaches A method for wireless communication at a first user equipment (UE) (Scenario 100 involves UE 1, which may be a part of a wireless communication network (e.g., an NR network), Para. 23, FIG. 1) served by a cell associated with a network entity (a TRP may be a gNB in a 5G/NR network, Para. 22. Scenario 100 involves TRP 1, Para. 23, FIG. 1), comprising: receiving a configuration (The CLI measurement configuration of the CLI RS, Para. 72) for receiving a cross-link interference (CLI) sounding reference signal (SRS) in a slot (CLI measurement in the first measurement slot, Para. 71, FIG. 6. The CLI RS may comprise at least a sounding reference signal (SRS), Para. 72, FIG. 6) based at least in part on a downlink symbol (a symbol number of the CLI RS, Para. 26. In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2) or a flexible symbol of a first symbol pattern (The CLI measurement configuration may comprise at least one of a node identity (ID), a time-frequency location, a slot number or a symbol number of the CLI RS, Para. 26. In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2) for the first UE (Scenario 100 involves UE 1, Para. 23, FIG. 1).
Yang teaches, wherein the first symbol pattern for the slot (The CLI measurement configuration may comprise at least one of a node identity (ID), a time-frequency location, a slot number or a symbol number of the CLI RS, Para. 26. In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2) is indicated by a UE-specific (The CLI measurement configuration may comprise a node identity (ID), Para. 26, 50) time division duplexing (TDD) configuration (In New Radio (NR), dynamic time division duplex (TDD) and mini-slot transmission were introduced, Para. 5. At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) for the first UE (each UE may receive the CLI measurement configuration to determine whether to transmit the CLI RS (e.g., SRS) or measure CLI RS (e.g., SRS) in each time interval (e.g. slot). In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2).
Yang teaches the UE-specific (The CLI measurement configuration may comprise a node identity (ID), Para. 26, 50) TDD configuration (The UE may be configured to measure the received power over SRS resource(s) (e.g. REs occupied by SRSs), Para. 38, FIG. 3. At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) indicating which symbols of the slot are configured for the first UE as uplink symbols (Slot 302 may comprise an UL data region (e.g., physical uplink shared channel (PUSCH)) and an ULCC region, Para. 39, FIG. 3) and which symbols of the slot are configured for the first UE as downlink symbols (Slot 302 may comprise a DLCC region, a CLI-RS (e.g., SRS) region, Para. 39, FIG. 3).
Yang teaches a single port for reception (receive, via transceiver 516, Para. 50, FIG. 5) and measurement of the CLI SRS (CLI measurement in the first measurement slot, Para. 71, FIG. 6. The CLI RS may comprise at least a sounding reference signal (SRS), Para. 72, FIG. 6).
Yang teaches the single port being a first port (receive, via transceiver 516, Para. 50, FIG. 5) of a plurality of ports (transceiver 516 and transceiver 526, Para. 49, FIG. 5).
Yang teaches performing the measurement (At 650, process 600 may involve apparatus 510 performing the CLI measurement in the first measurement slot, Para. 71, FIG. 6) on the CLI SRS in the slot (At 640, process 600 may involve apparatus 510 receiving a CLI reference signal (RS) in the first measurement slot, Para. 70, FIG. 6) via the single port (receive, via transceiver 516, Para. 50, FIG. 5) based at least in part on the configuration (In New Radio (NR), dynamic time division duplex (TDD) and mini-slot transmission were introduced, Para. 5. At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) for receiving the CLI SRS (At 640, process 600 may involve apparatus 510 receiving a CLI reference signal (RS) in the first measurement slot, Para. 70, FIG. 6).
Although Yang teaches a configuration for receiving the CLI SRS and teaches a single port for reception and measurement of the CLI SRS, Yang fails to teach wherein the configuration for receiving the signal indicates: an aperiodic transmission of signal resources, and an index of a single port, and although Yang teaches a plurality of ports, Yang fails to teach a plurality of ports of the first UE.
Yum teaches wherein the configuration for receiving the signal (a timing at which interference is measured in a corresponding resource may be indicated by DCI, Para. 201) indicates: an aperiodic transmission of signal resources (an interference measurement resource (IMR) based on a zero power channel state information-reference signal (ZP CSI-RS) is used to measure inter-cell interference, Para. 153. The eNB may configure a port-wise IMR (PIMR) for the UE, Para. 156. It is configured whether a corresponding PIMR is aperiodic, Para. 199. When the PIMR is limited to an aperiodic PIMR, a periodicity configuration may not be used separately. In this case, a timing at which interference is measured in a corresponding resource may be indicated by DCI, Para. 201), and an index of a single port (the eNB may transmit port index(s) in DCI to the UEs, Para. 175) for reception and measurement of the signal (interference measurements of the ports of the indexes, Para. 175), the single port (port index(s) in DCI, Para. 175) being a first port of a plurality of ports of the first UE (each of the port groups may include a plurality of ports, Para. 8. With knowledge of different hypotheses being applied to different ports, the UE measures interference independently for each port, Para. 156).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Yum with the teachings of Yang since Yum provides a technique for indicating a port index through DCI for measuring interference, which can be introduced into the system of Yang to permit CLI measurement configurations to specify a port index among port indexes in which UE is to measure CLI.
In regard to Claim 6, Yang teaches the measurement is a reference signal strength indicator (RSSI) measurement or a reference signal received power (RSRP) measurement (The UE may be configured to measure the reference symbol received power (RSRP) of each SRS, Para. 35).
In regard to Claim 7, Yang teaches reporting the measurement for the CLI SRS to the network entity (the TRP determine to instruct its UEs to measure the SRS in the measurement slots. After measuring the CLI, the UE may be configured to feedback the measurement report to its serving TRP, Para. 34).
In regard to Claim 8, Yang teaches the measurement for the CLI SRS is configured to be performed aperiodically, semi-persistently, or periodically (the CLI measurement configuration may indicates periodic measurement slots, Para. 72).
In regard to Claim 11, Yang teaches the first UE (Scenario 100 involves UE 1, Para. 23, FIG. 1) associated with the first symbol pattern (The CLI measurement configuration may comprise at least one of a node identity (ID), a time-frequency location, a slot number or a symbol number of the CLI RS, Para. 26. In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2) is served by a first cell of a first network entity (Link 1 may be established between TRP 1 and UE 1 for data transmission between TRP 1 and UE 1, Para. 23, FIG. 1) and a second UE (each UE may receive the CLI measurement configuration to determine whether to transmit the CLI RS (e.g., SRS) or measure CLI RS (e.g., SRS) in each time interval (e.g. slot). In the third time interval, UE 2 may be configured to transmit the CLI RS, Para. 29, FIG. 2) associated with a second symbol pattern (The CLI measurement configuration may comprise at least one of a node identity (ID), a time-frequency location, a slot number or a symbol number of the CLI RS, Para. 26. In the third time interval, UE 2 may be configured to transmit the CLI RS, Para. 29, FIG. 2) is served by a second cell of a second, different network entity (Link 1 may be established between TRP 1 and UE 1 for data transmission between TRP 1 and UE 1. Link 2 may be established between TRP 2 and UE 2 for data transmission between TRP 2 and UE 2, Para. 23, FIG. 1).
In regard to Claim 29, Yang teaches An apparatus for wireless communication at a first user equipment (UE) (Scenario 100 involves UE 1, which may be a part of a wireless communication network (e.g., an NR network), Para. 23, FIG. 1) served by a cell associated with a network entity (a TRP may be a gNB in a 5G/NR network, Para. 22.

The CLI RS may comprise at least a sounding reference signal (SRS), Para. 72, FIG. 6) based at least in part on a downlink symbol (a symbol number of the CLI RS, Para. 26. In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2) or a flexible symbol of a first symbol pattern (The CLI measurement configuration may comprise at least one of a node identity (ID), a time-frequency location, a slot number or a symbol number of the CLI RS, Para. 26.

At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) for the first UE (each UE may receive the CLI measurement configuration to determine whether to transmit the CLI RS (e.g., SRS) or measure CLI RS (e.g., SRS) in each time interval (e.g. slot). In the third time interval, UE 1 may be configured to receive the CLI RS, Para. 29, FIG. 2).

At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) for receiving the CLI SRS (At 640, process 600 may involve apparatus 510 receiving a CLI reference signal (RS) in the first measurement slot, Para. 70, FIG. 6).
Although Yang teaches a configuration for receiving the CLI SRS and teaches a single port for reception and measurement of the CLI SRS, Yang fails to teach the configuration for receiving the signal indicates: an aperiodic transmission of signal resources, and an index of a single port, and although Yang teaches a plurality of ports, Yang fails to teach a plurality of ports of the first UE.
Yum teaches the configuration for receiving the signal (a timing at which interference is measured in a corresponding resource may be indicated by DCI, Para. 201) indicates: an aperiodic transmission of signal resources (an interference measurement resource (IMR) based on a zero power channel state information-reference signal (ZP CSI-RS) is used to measure inter-cell interference, Para. 153.

Yang teaches the UE-specific (The CLI measurement configuration may comprise a node identity (ID), Para. 26, 50) TDD configuration (The UE may be configured to measure the received power over SRS resource(s) (e.g. REs occupied by SRSs), Para. 38, FIG. 3. At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) indicating which symbols of the slot are configured for the second UE as uplink symbols (Slot 302 may comprise an UL data region (e.g., physical uplink shared channel (PUSCH)) and an ULCC region, Para. 39, FIG. 3) and which symbols of the slot are configured for the second UE as downlink symbols (Slot 302 may comprise a DLCC region, a CLI-RS (e.g., SRS) region, Para. 39, FIG. 3).
Yang teaches receiving a second configuration (The CLI measurement configuration of the CLI RS, Para. 72) [the examiner notes that there is no limitation requiring that a “first configuration” is different from a “second configuration”] for transmitting a second CLI SRS (in the first time interval, UE 1 may be configured to transmit the CLI RS, Para. 29, FIG. 2), wherein the second configuration configures the second CLI SRS according to one or more of a first set of symbols (The CLI measurement configuration may comprise at least one of a slot number or a symbol number of the CLI RS, Para. 72).
Yang teaches wherein the first configuration (The CLI measurement configuration of the CLI RS, Para. 72) configures the first CLI SRS for transmission (In the second time interval, UE 1 may be configured to transmit the CLI RS, Para. 29, FIG. 2) according to one or more of a second set of symbols of the slot not subject to the restriction (The CLI measurement configuration may comprise at least one of a slot number or a symbol number of the CLI RS, Para. 72).
Yang teaches transmitting, to the second UE, the first CLI SRS in the slot (In the second time interval, UE 1 may be configured to transmit the CLI RS and UE 2 may be configured to receive the CLI RS, Para. 29, FIG. 2) according to the first configuration (In New Radio (NR), dynamic time division duplex (TDD) and mini-slot transmission were introduced, Para. 5. At 610, process 600 may involve apparatus 510, as a first node of a wireless network, receiving a cross-link interference (CLI) measurement configuration, Para. 67, FIGS. 1, 5, 6) for transmitting the first CLI SRS (In the second time interval, UE 1 may be configured to transmit the CLI RS, Para. 29, FIG. 2).
Although Yang teaches a first configuration for transmitting, Yang fails to teach wherein the first configuration for transmitting the first CLI SRS indicates: an aperiodic transmission of SRS resources, and a single port for transmission of the first CLI SRS, the single port being a first port of a plurality of ports, and although Yang teaches the second configuration configures the second CLI SRS according to one or more of a first set of symbols, Yang fails to teach a first set of symbols subject to a restriction, the restriction being for a slot placement of CLI SRS transmitted for measurement by the network entity.
Eyuboglu teaches wherein the first configuration (UE can be configured with multiple SRS resource sets, Col. 61, lines 55-60. The MNC requests all RF nodes in the vicinity of the UE to perform SRS measurements, Col. 62, lines 5-7. UEs (or MPs) are capable of performing beam measurements to detect cross-link interference from neighboring UEs (or MPs), for example using SRS measurements, and report it to their serving RF node, Col. 125, lines 44-49. All neighboring RF nodes may measure the total received power from these transmissions and report it to their serving RF nodes. For example, when a UE (or MP) reports that it is subject to cross-link interference from a neighboring UE, Col. 125, lines 49-61) for transmitting the first CLI SRS (To allow other UEs to measure cross-link interference, in some applications, UEs are configured to transmit SRS, Col. 101, lines 9-11) indicates: an aperiodic transmission of SRS resources (An SRS resource is also associated with a DL reference signal resource; i.e., CSI-RS, Col. 62, lines 1-2. CSI-RS transmissions can be aperiodic, Col. 62, lines 31-32), and a single port for transmission of the first CLI SRS (In some deployments, the SRS configuration 691 may be for a 1-antenna port, Col. 76, lines 62-66, FIG. 69), the single port being a first port of a plurality of ports (the SRS configuration 691 may be for a 1-antenna port or a 2-antenna port SRS transmission, meaning that the reference signal is transmitted using up to 2 digital antenna ports, Col. 76, lines 62-66, FIG. 69).
Eyuboglu teaches a first set of symbols (each SRS transmission occupies 1 OFDM symbol in certain designated slots, Col. 114, lines 33-37. Symbol positions {10-13} in the last 16 slots, Col. 117, lines 50-52) subject to a restriction, the restriction being for a slot placement of CLI SRS transmitted (the UE is further configured for M periodic SRS transmissions, where each SRS transmission occupies 1 OFDM symbol in certain designated slots, Col. 114, lines 33-37. Symbol positions {10-13} in the last 16 slots of every 80-slot 5 ms half-frame are set aside for RF nodes to receive SRS transmissions from the UEs, Col. 117, lines 50-52) for measurement by the network entity (MP-GWs also wirelessly transmit/receive information to/from other Mesh Points (MPs) in the mesh network, Col. 19, lines 56-59. MPs are capable of performing beam measurements to detect cross-link interference from neighboring UEs (or MPs), for example using SRS measurements, Col. 125, lines 44-49).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Eyuboglu with the teachings of Yang since Eyuboglu provides a technique for UEs to measure cross-link interference from neighboring UEs in relation to SRS transmissions of an antenna port, which can be introduced into the system of Yang to permit accurate CLI measurements by a UE through a CLI measurement configuration that indicates an antenna port involving a specific CLI RS resource arrangement for SRS.
Although Yang in view of Eyuboglu teaches a single port, Yang in view of Eyuboglu fails to teach an index of a single port, and although Yang in view of Eyuboglu teaches a plurality of ports, Yang in view of Eyuboglu fails to teach a plurality of ports of the first UE.
Yum teaches wherein the first configuration for transmitting the first signal (a timing at which interference is measured in a corresponding resource may be indicated by DCI, Para. 201) indicates: an index of a single port (the eNB may transmit port index(s) in DCI to the UEs, Para. 175).
Yum teaches the single port (port index(s) in DCI, Para. 175) being a first port of a plurality of ports of the first UE (each of the port groups may include a plurality of ports, Para. 8. With knowledge of different hypotheses being applied to different ports, the UE measures interference independently for each port, Para. 156).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Yum with the teachings of Yang in view of Eyuboglu since Yum provides a technique for indicating a port index through DCI for measuring interference, which can be introduced into the system of Yang in view of Eyuboglu to permit CLI measurement configurations to specify a port index among port indexes in which UE is to measure CLI.
In regard to Claim 23, Yang teaches the first CLI SRS is configured to be transmitted aperiodically, semi-persistently, or periodically (the CLI measurement configuration may indicates periodic measurement slots, Para. 72).

Link 2 may be established between TRP 2 and UE 2 for data transmission between TRP 2 and UE 2, Para. 23, FIG. 1).

Yang in view of Yum fails to teach the SRS is configured to be transmitted according to interlaced frequency resources in accordance with a frequency domain comb and a frequency domain comb offset.
Stirling teaches the SRS is configured to be transmitted according to interlaced frequency resources in accordance with a frequency domain comb and a frequency domain comb offset (the TRP may provide to the UE the following configuration parameters: TRP or UE specific parameters Number of symbols and/or subframes per different UE communications beam, and Number of symbols and/or subframes for different TRP communications beam, Col. 18, lines 34-54. Additional configuration information may be provided by the TRP in the deployment using the modified SRS resource. The additional configuration information includes: TRP specific SRS configuration Frequency comb spacing, e.g., 2, 4, and so on. UE specific configuration UE specific subcarrier offset for the first RF chain of the frequency comb, Col. 18, lines 55-67).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Stirling with the teachings of Yang in view of Yum since Stirling provides a technique for configuring SRS resources involving a frequency comb, which can be introduced into the system of Yang in view of Yum to permit appropriate detailed configuration of symbol resources among communication beams and related offset values of frequency comb.
Claim(s) 34 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yang in view of Yum, and further in view of Senthilkumar (Pub. No.: US 20150019712 A1), hereafter referred to as Senthilkumar.
In regard to Claim 34, as presented in the rejection of Claim 1, Yang in view of Yum teaches the single port for reception and measurement of the CLI SRS.
Yang in view of Yum fails to teach the index of the single port is equal to 1000.
Senthilkumar teaches the index of the single port is equal to 1000 (Base port 1, Interface Index number 1000, Para. 16, Table 1).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Senthilkumar with the teachings of Yang in view of Yum since Senthilkumar provides a technique for indicating a specific number of an index for a port, which can be introduced into the system of Yang in view of Yum to permit a TRP to provide a specific number of an index for a port to a UE.
Claim(s) 35 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yang in view of Eyuboglu, Yum, and further in view of Senthilkumar (Pub. No.: US 20150019712 A1), hereafter referred to as Senthilkumar.
In regard to Claim 35, as presented in the rejection of Claim 13, Yang in view of Eyuboglu and Yum teaches the single port for transmission of the first CLI SRS.
Yang in view of Eyuboglu and Yum fails to teach the index of the single port is equal to 1000.
Senthilkumar teaches the index of the single port is equal to 1000 (Base port 1, Interface Index number 1000, Para. 16, Table 1).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Senthilkumar with the teachings of Yang in view of Yum since Senthilkumar provides a technique for indicating a specific number of an index for a port, which can be introduced into the system of Yang in view of Yum to permit a TRP to provide a specific number of an index for a port to a UE.
Response to Arguments
I. Arguments for the Claim Rejections under 35 USC § 103
Applicant's arguments filed 7/6/2026 have been fully considered but they are not persuasive. Page 10 of the Remarks presents the argument that However, Yang does not teach or suggest that "the configuration for receiving the CLI SRS indicates ... an index of a single port for reception and measurement of the CLI SRS," as recited in amended independent claim 1. This argument is not persuasive. The limitations introduced by the amendments of Claims 1, 13, 29 and 31, which are not taught by Yang, are taught by Yum et al. (Pub. No.: US 20210160718 A1).
