Response to Remarks/Arguments
Applicant’s remarks/arguments (page 9-17), filed on 5/20/2026, with respect to the independent claims
1, 7, and 13 have been fully considered but are not persuasive.
Regarding remarks in page 11 for independent claims 1, 7, and 13, applicant asserts that Yoon has no teaching or suggestion of measuring at least one neighbor beam outside of a measurement interval, e.g., no teaching or suggestion of measuring at least one neighbor beam regardless of a measurement gap and while the communication is maintained with the serving beam.
Examiner respectfully disagrees with the applicant. YOON et al. (US 2021/0144573 Al) discloses (the UE may attempt to detect the neighbor cell or measure the received quality of the neighboring cell while maintaining a beam which is formed to be suitable for the serving cell so as not to disconnect communication with the serving cell, Yoon: [0106]-[0107]. The UE may communicate with the serving cell and simultaneously measure the received quality of the neighboring cells using the omnidirectionally formed beams, Yoon: [0112]. when the UE is configured with multiple RF modules and antenna modules, it is not necessary to use all the RF modules and antenna modules for measurement of the received quality of neighboring cells. The remaining antenna modules except for the antenna modules used to communicate with the serving cell may be used to perform operations of forming beams in various directions, detecting neighboring cells using the beams formed in various directions, searching for beams optimized for the neighboring cells, and measuring the received quality of the neighboring cells, Yoon: [0125]. even when the UE performs an operation of measuring the received quality of the neighboring cells without an additional report or indication, a condition for performing the measurement operation may be determined based on a configuration of the gNB, Yoon: [0132]. When the measurement interval is aperiodically configured, the gNB may configure the measurement interval for the UE when the quality of the serving cell is lower than a preset threshold, Yoon: [0137]. since the UE receives signals using the same reception beam with respect to all cells, the UE may receive signals from the neighboring cell or perform measurement for various signals, even while the UE receives signals from the serving cell, Yoon: [0099]. if the received quality of the serving cell is higher than a threshold level, the received quality of the neighboring cells is not measured and, if the received quality of the serving cell is lower than the threshold level, the received quality of the neighboring cells may be measured. Yoon: [0101]).
Regarding remarks in page 13 for independent claims 1, 7, and 13, applicant asserts that Yoon does not disclose or suggest a configuration in which measurements of neighbor beams are performed by the second RF module based on the reception quality of the serving beam received via the first RF module, independently of any measurement gap.
YOON discloses (If the measured received quality of the serving cell is lower than the threshold, the UE reports a measurement result to the gNB. the UE may attempt to detect the neighbor cell or measure the received quality of the neighboring cell while maintaining a beam which is formed to be suitable for the serving cell so as not to disconnect communication with the serving cell, Yoon: [0106]-[0107]. when the UE is configured with multiple RF modules and antenna modules, it is not necessary to use all the RF modules and antenna modules for measurement of the received quality of neighboring cells. The remaining antenna modules except for the antenna modules used to communicate with the serving cell may be used to perform operations of forming beams in various directions, detecting neighboring cells using the beams formed in various directions, searching for beams optimized for the neighboring cells, and measuring the received quality of the neighboring cells, Yoon: [0125]. even when the UE performs an operation of measuring the received quality of the neighboring cells without an additional report or indication, a condition for performing the measurement operation may be determined based on a configuration of the gNB, Yoon: [0132]. if the received quality of the serving cell is higher than a threshold level, the received quality of the neighboring cells is not measured and, if the received quality of the serving cell is lower than the threshold level, the received quality of the neighboring cells may be measured. Yoon: [0101]).
Regarding remarks in page 14 for independent claims 1, 7, and 13, applicant asserts that YANG includes an operation of performing monitoring to determine whether to trigger a beam switch, without mentioning the operation of the UE conducting a call with the serving cell. Therefore, YANG cannot represent a configuration that performs measurements on neighboring cells independently of measurement intervals while maintaining communication with the serving cell.
YANG et al. (US 2020/0178134 Al) discloses (a UE may transmit a beam failure recovery request to a base station, and the request may include a new candidate beam recommended to the base station. After receiving the request, the base station may transmit a response signaling to the UE, and the response signaling may include switching to a new candidate beam, or restarting a beam search, or other indication. This beam failure recovery mechanism can make the UE or the base station quickly switch to a standby beam pair link, including a transmission beam and a reception beam) to continue transmitting control messages and data, thereby achieving a rapid beam recovery, Yang: [0013]. The mobile terminal shown in FIG. 6 includes a first monitoring module and a first processing module. The first monitoring module is configured to monitor whether a first blockage event occurs to an antenna of a terminal. The first processing module is configured to transmit a beam switching request to a network-side device, in a case that the first blockage event occurs, Yang: [0120]-[0121]. mobile terminal further includes: a first receiving module, configured to receive a beam switching response fed back by the network-side device according to the beam switching request, Yang: [0135]. the mobile terminal shown in FIG. 9 includes a second monitoring module and a second processing module. The second monitoring module is configured to monitor received signal strength information of at least one beam link. The second processing module is configured to determine that a second blockage event occurs to an antenna of a terminal and transmit a beam switching request to a network-side device, in a case that the number of beam links whose received signal strength information meets a second preset condition is greater than or equal to a third predetermined number. Yang: [0138]-[0140]).
Regarding remarks in page 15 for independent claims 1, 7, and 13, applicant asserts that Hirzallah does not use RSSI or RFFP for power loss estimation across multiple modules. Nor does Hirzallah appear to disclose a UE selecting and "activating" a specific RF module based on an estimated power loss for communication with a serving beam.
In the application specification, the power loss is a product of transmit power and described as “the power loss estimator 252 is configured to estimate the power loss by estimating Equivalent Isotropically Radiated Power (EIPR) loss and Effective Isotropic Sensitivity (EIS) loss. The EIPR loss is a product of transmitter power and the antenna gain in a given direction relative to an isotropic antenna of a radio transmitter. The EIS is the measured sensitivity in a single direction. The Effective Isotropic Radiated Power (EIRP) loss and Effective Isotropic Sensitivity (EIS) loss is observed in the UE 200 due to mismatch in Intermediate frequency (IF) cable lengths from each RF module to a trans-receiver of the UE 200, Specification [0040]”. HIRZALLAH et al. (US 2023/0179953 Al) discloses ("the at least one beam feature may include one or more of: a beam shape, a CDF or a PDF of beam-based spherical EIRP measurements, a beam configuration, a beam measurement, or a beam embedding based on a GCN (e.g., as described in connection with FIG. 15). In addition, the at least one beam feature may be associated with at least one of a transmission beam at a transmitting device or a reception beam at a receiving device, Hirzallah: [0135], [0154], [0199]").

The mobile terminal shown in FIG. 6 includes a first monitoring module and a first processing module.

Yet, Yoon in view of Yang does not explicitly disclose:

Hirzallah: [0135], [0154], [0199]).
