Office Action

§103
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 1-2, 5-9, 13-17 and 19-24 are rejected under 35 U.S.C. 103 as being unpatentable over Kunt et al. (U.S. PGPub 2023/0189179), hereinafter referred to as Kunt in view of Liu et al. (U.S. PGPub 2023/0239823), hereinafter referred to as Liu. Regarding claim 1, Kunt teaches an apparatus (communication apparatus; See Fig. 2, #210), comprising: a memory (See Fig. 2, #214); and a processor (See Fig. 2, #212) coupled to the memory, the processor configured to cause the apparatus to: transmit a timing advance value in a data message (the UE sends TA report in Msg3; See [0113]), the timing advance value being based at least in part on a time offset value (UE 110 may be configured to transmit a TA report to network node 125 in response to a value of TA deviating from a threshold by at least a predefined amount; See [0030] and [0056]). Kunt fails to teach the time offset value pertaining to a timing advance of an uplink time slot before a corresponding downlink time slot. Liu teaches the time offset value pertaining to a timing advance of an uplink time slot before a corresponding downlink time slot (the TA offset is the time difference between the UL transmission (UL signal starting time, or UL OFDM symbol starting time) and the corresponding DL signal (the first path, the strongest path, or the OFDM symbol starting boundary inferred by the UE); See [0116]). Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the apparatus of Kunt to include the time offset value pertaining to a timing advance of an uplink time slot before a corresponding downlink time slot taught by Liu in order to improve signaling synchronization and reliability. Regarding claim 2, Kunt further teaches the apparatus of claim 1, wherein the time offset value comprises a time value (at time t1, if the current TA value (that is, the actual TA value currently obtained by the computing or measuring) deviates from the previous TA value: TA_old, reported at time t0, by at least a predefined amount, such as TA>=TA_old+Delta_hys or TA<=TA_old-Delta_hyss, then UE sends a new TA report, where Delta_hys is a Delta hysteresis; See [0056]). Regarding claim 5, Kunt further teaches the apparatus of claim 1, wherein, the processor is configured to cause the apparatus to transmit one or more of a first reported value or a second reported value, and the one or more of the first reported value or the second reported value is further determined by at least one of a network deployment or a set of threshold values (The processor 212 may monitor the TA/KI value and when the TA/KI value is outside a hysteresis range, or when the TA/KI value is greater than or lower than a predetermined threshold, or when the TA/KI value is deviating from a threshold by at least a predefined amount, the UE 110 may initiate the TA report. At time t1, if the current TA value (that is, the actual TA value currently obtained by the computing or measuring) deviates from the previous TA value: TA_old, reported at time t0, by at least a predefined amount, such as TA>=TA_old+Delta_hys or TA<=TA_old-Delta_hyss, then UE sends a new TA report, where Delta_hys is a Delta hysteresis. At time t1, if the current KI value deviates from the previous KI value: KI_old, reported at time t0, by at least a predefined amount, such as KI>=KI_old+Delta_hys or KI<=KI_old-Delta_hys, then UE sends a new TA report; See [0055]-[0057]). Regarding claim 6, Kunt fails to teach the apparatus of claim 2, wherein, the time offset value is specified in unit of a symbol sample. Liu teaches wherein, the time offset value is specified in unit of a symbol sample (the TA offset is the time difference between the UL transmission (UL signal starting time, or UL OFDM symbol starting time) and the corresponding DL signal (the first path, the strongest path, or the OFDM symbol starting boundary inferred by the UE); See [0116]). Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the apparatus of Kunt to include wherein, the time offset value is specified in unit of a symbol sample taught by Liu in order to improve signaling synchronization and reliability. Regarding claim 7, Kunt further teaches the apparatus of claim 2, wherein the time offset value indicates whether the time offset value is positive or negative in a time period (at time t1, if the current TA value (that is, the actual TA value currently obtained by the computing or measuring) deviates from the previous TA value: TA_old, reported at time t0, by at least a predefined amount, such as TA>=TA_old+Delta_hys or TA<=TA_old-Delta_hyss, then UE sends a new TA report, where Delta_hys is a Delta hysteresis; See [0056]). Regarding claim 8, Kunt further teaches the apparatus of claim 1, wherein the processor is configured to cause the apparatus to receive a configuration of a reporting period (UE 110 may be configured to autonomously transmit its TA report to network node 125 periodically or non-periodically; See [0030]) and transmit a reported value based on the reporting period (The UE 110 may transmit its TA report to network node 125, periodically or non-periodically, responsive to expiry of a timer; See [0058]). Regarding claim 9, Kunt further teaches the apparatus of claim 1, wherein transmission of the timing advance value is triggered by a differential offset value being larger, smaller, or equal to a threshold (The processor 212 may monitor the TA/KI value and when the TA/KI value is outside a hysteresis range, or when the TA/KI value is greater than or lower than a predetermined threshold, or when the TA/KI value is deviating from a threshold by at least a predefined amount, the UE 110 may initiate the TA report At time t1, if the current TA value (that is, the actual TA value currently obtained by the computing or measuring) deviates from the previous TA value: TA_old, reported at time t0, by at least a predefined amount, such as TA>=TA_old+Delta_hys or TA<=TA_old-Delta_hyss, then UE sends a new TA report, where Delta_hys is a Delta hysteresis; See [0055]-[0056]). Regarding claim 13, Kunt fails to teach the apparatus of claim 1, wherein the time offset value is specified in unit of symbol sample. Liu teaches wherein, the time offset value is specified in unit of a symbol sample (the TA offset is the time difference between the UL transmission (UL signal starting time, or UL OFDM symbol starting time) and the corresponding DL signal (the first path, the strongest path, or the OFDM symbol starting boundary inferred by the UE); See [0116]). Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the apparatus of Kunt to include wherein, the time offset value is specified in unit of a symbol sample taught by Liu in order to improve signaling synchronization and reliability. Regarding claim 14, Kunt further teaches the apparatus of claim 1, wherein the processor is configured to cause the apparatus to transmit the timing advance value based at least in part on a differential time offset value being larger than or equal to a second threshold (The processor 212 may monitor the TA/KI value and when the TA/KI value is outside a hysteresis range, or when the TA/KI value is greater than or lower than a predetermined threshold, or when the TA/KI value is deviating from a threshold by at least a predefined amount, the UE 110 may initiate the TA report. At time t1, if the current KI value deviates from the previous KI value: KI_old, reported at time t0, by at least a predefined amount, such as KI>=KI_old+Delta_hys or KI<=KI_old-Delta_hys, then UE sends a new TA report; See [0055] and [0057]). Regarding claim 15, Kunt further teaches the apparatus of claim 14, wherein the differential time offset value comprises a variation between a current timing advance value and a previous timing advance value (at time t1, if the current KI value deviates from the previous KI value: KI_old, reported at time t0, by at least a predefined amount, such as KI>=KI_old+Delta_hys or KI<=KI_old-Delta_hys, then UE sends a new TA report; See [0057]). Regarding claim 16, Kunt teaches a method, comprising: transmitting a timing advance value in a data message (the UE sends TA report in Msg3; See [0113]), the timing advance value being based at least in part on a time offset value (UE 110 may be configured to transmit a TA report to network node 125 in response to a value of TA deviating from a threshold by at least a predefined amount; See [0030] and [0056]). Kunt fails to teach the time offset value pertaining to a timing advance of an uplink time slot before a corresponding downlink time slot. Liu teaches the time offset value pertaining to a timing advance of an uplink time slot before a corresponding downlink time slot (the TA offset is the time difference between the UL transmission (UL signal starting time, or UL OFDM symbol starting time) and the corresponding DL signal (the first path, the strongest path, or the OFDM symbol starting boundary inferred by the UE); See [0116]). Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Kunt to include the time offset value pertaining to a timing advance of an uplink time slot before a corresponding downlink time slot taught by Liu in order to improve signaling synchronization and reliability. Regarding claim 17, Kunt further teaches the method of claim 16, wherein the time offset value comprises a time value (at time t1, if the current TA value (that is, the actual TA value currently obtained by the computing or measuring) deviates from the previous TA value: TA_old, reported at time t0, by at least a predefined amount, such as TA>=TA_old+Delta_hys or TA<=TA_old-Delta_hyss, then UE sends a new TA report, where Delta_hys is a Delta hysteresis; See [0056]). Regarding claim 19, Kunt further teaches the method of claim 16, further comprising transmitting one or more of a first reported value or a second reported value and determining the one or more of the first reported value or the second reported value by at least one of a network deployment or a set of threshold values (The processor 212 may monitor the TA/KI value and when the TA/KI value is outside a hysteresis range, or when the TA/KI value is greater than or lower than a predetermined threshold, or when the TA/KI value is deviating from a threshold by at least a predefined amount, the UE 110 may initiate the TA report.

Regarding claim 20, Kunt fails to teach the method of claim 17, wherein the time offset value is specified in unit of a symbol sample. Liu teaches wherein, the time offset value is specified in unit of a symbol sample (the TA offset is the time difference between the UL transmission (UL signal starting time, or UL OFDM symbol starting time) and the corresponding DL signal (the first path, the strongest path, or the OFDM symbol starting boundary inferred by the UE); See [0116]). Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Kunt to include wherein, the time offset value is specified in unit of a symbol sample taught by Liu in order to improve signaling synchronization and reliability. Regarding claim 21, Kunt further teaches the method of claim 17, wherein, the time offset value indicates whether the time offset value is positive or negative in a time period (at time t1, if the current TA value (that is, the actual TA value currently obtained by the computing or measuring) deviates from the previous TA value: TA_old, reported at time t0, by at least a predefined amount, such as TA>=TA_old+Delta_hys or TA<=TA_old-Delta_hyss, then UE sends a new TA report, where Delta_hys is a Delta hysteresis; See [0056]).
