Response to Amendment
The Amendment filed on 1/21/2026 has been entered.
Response to Remarks/Arguments
Applicant’s remarks/arguments (page 2-13), filed on 1/21/2026, with respect to claim 1 have been fully
considered but are not persuasive.
Regarding remarks in page 6 for independent claim 1, applicant argues that Applicant assert without amendment regarding obviousness (motivation) of independent claim 1: The Examiner's arguments that individual claim features are present in various references coupled with descriptions of potential improvements provided by the claim features is NOT a clear articulation of the reasons WHY the claimed invention would have been obvious. The Examiner has merely argued that claim features are present in Cui and/or Chen references without providing clear articulation WHY the claimed invention would have been obvious, which amounts to impermissible hindsight.
DEJARDIN (US 2019/0253097 Al) discloses (isolation requires significant physical separation around one wavelength. Thus, for radio modules, the order of magnitude of the physical separation is necessary between two radio modules. It is however not always possible to guarantee such isolation, in particular for radio modules integrated in electronic devices with a low shape factor, such as ones sharing the same radio antenna.
The electronic device being arranged for determining, for each radio module, a value of an attenuation associated with said radio module, the value of the attenuation being determined according to a maximum power acceptable to said radio module, a transmission power of the other radio module and isolation between the first and second radio interfaces. the value of the attenuation necessary depends on the power of the radio signal transmitted by the first radio module, the maximum power acceptable to the second radio module and the isolation between the two radio modules.
The value of the attenuation being determined according to a maximum power acceptable to said radio module, a maximum transmission power of the other radio module and an isolation between the first and second radio interfaces. The attenuation associated with a first radio module thus corresponds to an attenuation value making it possible to sufficiently attenuate a radio signal transmitted by the second radio module so as not to saturate the radio interface of the first radio module, the received power then being lower than the maximum power acceptable to the first radio module. This is because the isolation and attenuation make it possible to reduce the received power of the radio signal transmitted by the second radio module and received by the first radio module. This step may be renewed periodically, in particular if the transmission power of a radio module is variable over time. Thus a new attenuation value associated with a first radio module can be determined whenever the transmission power of the second radio module changes, and conversely for a new attenuation value associated with the second radio module, [0002], [0004]-0005], [0041]).
Regarding remarks in page 7 for independent claim 1, applicant argues that The Examiner argues that Figure 5 and paragraphs [0036] and [0063] of Brighenti teach or suggest features (A) and (B). Respectfully, none of Figure 5 or paragraphs [0036] or [0063] of Brighenti teach or suggests feature (A) and (B).
Examiner respectfully disagrees with the applicant. Brighenti et al. (US 2020/0305096 Al) discloses (a component of the DAS is configured to adjust the transmission power of the remote antenna unit 104 based on the number of users detected by the radar sensor and the distance of each user from the remote antenna unit. The remote antenna unit is configured to process the data from the radar sensor and adjust its own transmission power based on the data from the radar sensor. the radio point 206 communicates the user positions and user IDs to the controller 204 and the controller 204 triggers a request to the radio point 206 to adjust the radiating power levels based on the user positions in the coverage area. the transmission power is adjusted to a level such that the radio point 206 can provide coverage to the user that is farthest from the radio point 206 in the coverage area of the radio point. a component of the C-RAN system is configured to adjust the transmission power of the radio point based on the number of users detected by the radar sensor and the distance of each user from the radio point. the radio point is configured to process the data from the radar sensor and adjust its own transmission power based on the data from the radar sensor, Fig. 5, [0036], [0063]).
Regarding remarks in page 8 for independent claim 1, applicant argues that Mere mention of isolation between radio interfaces does not teach or suggest feature (C): wherein within the coverage area, the first downlink signals of the first radio unit are isolated from the second downlink signals of the second radio unit in the context of what the first downlink signals of the first radio unit and the second downlink signals of the second radio unit.
Examiner respectfully disagrees with the applicant. DEJARDIN teaches (the electronic device being arranged for determining, for each radio module, a value of an attenuation associated with said radio module, the value of the attenuation being determined according to a maximum power acceptable to said radio module, a transmission power of the other radio module and isolation between the first and second radio interfaces. the value of the attenuation being determined according to a maximum power acceptable to said radio module, a maximum transmission power of the other radio module and an isolation between the first and second radio interfaces. The attenuation associated with a first radio module thus corresponds to an attenuation value making it possible to sufficiently attenuate a radio signal transmitted by the second radio module so as not to saturate the radio interface of the first radio module, the received power then being lower than the maximum power acceptable to the first radio module. This is because the isolation and attenuation make it possible to reduce the received power of the radio signal transmitted by the second radio module and received by the first radio module. This step may be renewed periodically, in particular if the transmission power of a radio module is variable over time. A new attenuation value associated with a first radio module can be determined whenever the transmission power of the second radio module changes, and conversely for a new attenuation value associated with the second radio module, [0004] [0041]).
