Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1, 4, 7, 11, 13, 16, 19 and 25 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US Pat. Pub. 20240056919 to Haitao Li et al. (hereinafter Li).

[0223]-[0232] teaches receives ephemeris information via SIB as location information) the method comprising:
determining a satellite coverage time based at least in part on the ephemeris data; (LI para. [0113]-[0121] teaches determining satellite coverage based on ephemeris data)
performing a first measurement procedure to measure satellite signals during a first measurement time when the satellite coverage time is less than a first threshold; (LI para. [0246]-[0294] teaches “Introducing information related to the time” wherein the UE determines whether to perform RRM measurement relaxation according to time criterion according to different time thresholds. For example, para. [0258] and Fig. 11 teaches a time threshold of within [T4, T5] a UE is considered within a service range and would normally start measurements in the neighbor cell. )
and

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.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 2, 3, 9, 10, 12, 14, 15 rejected under 35 U.S.C. 103 as being unpatentable over Li in view of US Pat. Pub. 20240187901 to Jie Cui et al. (hereinafter Cui).
Regarding claim 2, Li, the primary reference, does NOT teach “The method of Claim 1, wherein the first measurement time is determined based at least in part on scaling a base time interval by a first scaling factor and the second measurement time is determined based at least in part on scaling the base time interval by a second scaling factor, the first scaling factor being less than the second scaling factor.”
In the analogous art of 3GPP 5G wireless communications, Cui teaches “wherein the first measurement time is determined based at least in part on scaling a base time interval by a first scaling factor and the second measurement time is determined based at least in part on scaling the base time interval by a second scaling factor, the first scaling factor being less than the second scaling factor.” (Cui teaches RRM relaxation in para. [0071]-[0081] wherein a first measurement time without relaxation is scaled as a 1, and with relaxation may have be scaled by scaling factor M. For example, when cDRX is configured or different relaxation schemes are enabled such as relaxation scheme 1 or relaxation scheme 2 etc.. Therefore, when no relaxation occurs, the scaling factor is lower, e.g. 1, and when relaxation occurs, the scaling factor can be, e.g., 3 mapped to a second scaling factor see para. [0081].)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Cui with Li to teach measurements of reference signals. Each of Li and Cui are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Cui in order to implement RRM relaxation schemes to provide additional power saving benefits via RRM relaxation including “future implementations of RRM relaxation techniques” as taught in Cui paras. [0022]-[0024].
Regarding claim 3, Li does NOT teach “The method of Claim 1, wherein measurements of the satellite signals are performed in a first repetition pattern during the first measurement time and measurements of the satellite signals are performed in a second repetition pattern during the second measurement time.”
In the analogous art of 3GPP 5G wireless communications, Cui teaches “wherein measurements of the satellite signals are performed in a first repetition pattern during the first measurement time and measurements of the satellite signals are performed in a second repetition pattern during the second measurement time.” (Cui teaches measurements in para. [0094] for RRM relaxation scheme 1, the measurement gap repetition periodicity (MGRP) may be extended by a scaling factor for the relaxation measurement time. Thus, when the MGRP is extended, there is a second repetition pattern during the relaxation period.)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Cui with Li to teach measurements of reference signals. Each of Li and Cui are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Cui in order to implement RRM relaxation schemes to provide additional power saving benefits via RRM relaxation including “future implementations of RRM relaxation techniques” as taught in Cui paras. [0022]-[0024].
Regarding claim 9, Li does NOT teach “The method of claim 1 wherein the first measurement procedure includes measurement on a first number of reference signals and the second measurement procedure includes measurement on a second number of reference signals.”
In the analogous art of 3GPP 5G wireless communications, Cui teaches “wherein the first measurement procedure includes measurement on a first number of reference signals and the second measurement procedure includes measurement on a second number of reference signals.” Cui para. [0011] teaches ( “To provide one example, when RRM relaxation is enabled, the UE may be configured to perform measurements and/or monitor for reference signals less frequently compared to other RRM measurement configurations.” Therefore, when relaxation is performed, fewer reference signals are measured than when normal RRM measurements take place.)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Cui with Li to teach measurements of reference signals. Each of Li and Cui are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Cui in order to implement RRM relaxation schemes to provide additional power saving benefits via RRM relaxation including “future implementations of RRM relaxation techniques” as taught in Cui paras. [0022]-[0024].
Regarding claim 10, Li does NOT teach “The method of Claim 1, further comprising sending measurement reports to the network node in a first repetition pattern during the first measurement time and sending measurement reports to the network node in a second repetition pattern during the second measurement time.”
In the analogous art of 3GPP 5G wireless communications, Cui teaches “sending measurement reports to the network node in a first repetition pattern during the first measurement time” Cui para. [0011] teaches ( “To provide one example, when RRM relaxation is enabled, the UE may be configured to perform measurements and/or monitor for reference signals less frequently compared to other RRM measurement configurations.” Therefore, before relaxation is performed, more reference signals are measured when normal RRM measurements take place, mapped to a “first repetition pattern” this is taught in Cui in para. [0015] as “a measurement gap pattern of Y seconds and a repetition period of X seconds”) and “sending measurement reports to the network node in a second repetition pattern during the second measurement time.” (Cui teaches in para. [0094] teaches a second repetition pattern during RRM relaxation, “for RRM relaxation scheme 1, the measurement gap repetition periodicity (MGRP) may be extended by scaling factor (G). The scaling factor may apply for all detection and measurement time period as long as MGRP is used and/or applies to the detection or measurement time lower boundary.” Therefore, the repetition pattern for prior to RRM relaxation and during RRM relaxation have different repetition patterns for the measurement times.)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Cui with Li to teach measurements of reference signals. Each of Li and Cui are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Cui in order to implement RRM relaxation schemes to provide additional power saving benefits via RRM relaxation including “future implementations of RRM relaxation techniques” as taught in Cui paras. [0022]-[0024].
Regarding claim 12, Li does NOT teach “The method of Claim 1, wherein at least one of the first measurement time and the second measurement time includes at least one of a cell detection time, a measurement period of a measurement, synchronization signal block, SSB, index acquisition time, measurement reporting delay, radio link monitoring, RLM, out of sync evaluation period, RLM in sync evaluation period, beam detection evaluation period, candidate beam detection evaluation period and measurement period of L1-measurement.”
In the analogous art of 3GPP 5G wireless communications, Cui teaches wherein at least one of the first measurement time and the second measurement time includes at least one of a cell detection time, a measurement period of a measurement, synchronization signal block, SSB, index acquisition time, measurement reporting delay, radio link monitoring, RLM, out of sync evaluation period, RLM in sync evaluation period, beam detection evaluation period, candidate beam detection evaluation period and measurement period of L1-measurement. (Cui teaches in para. [0076] that the RRM measurements include a measurement window and “that a measurement interval refers to the time interval between two successive physical layer measurement sampling points for the SSB with the same index of the target cell.” Therefore the SSB is included in the measurement time.)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Cui with Li to teach measurements of reference signals. Each of Li and Cui are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Cui in order to implement RRM relaxation schemes to provide additional power saving benefits via RRM relaxation including “future implementations of RRM relaxation techniques” as taught in Cui paras. [0022]-[0024].
Regarding claim 14, Li does NOT teach “The WD of claim 13, wherein the first measurement time is determined based at least in part on scaling a base time interval by a first scaling factor and the second measurement time is determined based at least in part on scaling the base time interval by a second scaling factor, the first scaling factor being less than the second scaling factor.” (Li teaches relaxation which is well known to include a scaling factor, but does not explicitly identify the relaxation period as a scaled measurement).
In the analogous art of 3GPP 5G wireless communications, Cui teaches “wherein the first measurement time is determined based at least in part on scaling a base time interval by a first scaling factor and the second measurement time is determined based at least in part on scaling the base time interval by a second scaling factor, the first scaling factor being less than the second scaling factor.” (Cui teaches RRM relaxation in para. [0071]-[0081] wherein a first measurement time without relaxation is scaled as a 1, and with relaxation may have be scaled by scaling factor M. For example, when cDRX is configured or different relaxation schemes are enabled such as relaxation scheme 1 or relaxation scheme 2 etc.. Therefore, when no relaxation occurs, the scaling factor is lower, e.g. 1, and when relaxation occurs, the scaling factor can be, e.g., 3 mapped to a second scaling factor see para. [0081].)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Cui with Li to teach measurements of reference signals. Each of Li and Cui are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Cui in order to implement RRM relaxation schemes to provide additional power saving benefits via RRM relaxation including “future implementations of RRM relaxation techniques” as taught in Cui paras. [0022]-[0024].
Regarding claim 15, Li does NOT teach “The WD of Claim 13, wherein measurements of the satellite signals are performed in a first repetition pattern during the first measurement time and measurements of the satellite signals are performed in a second repetition pattern during the second measurement time.”
In the analogous art of 3GPP 5G wireless communications, Cui combined with Li teaches “wherein measurements of the satellite signals are performed in a first repetition pattern during the first measurement time and measurements of the satellite signals are performed in a second repetition pattern during the second measurement time.” (Cui teaches measurements in para. [0094] for RRM relaxation scheme 1, the measurement gap repetition periodicity (MGRP) may be extended by a scaling factor for the relaxation measurement time. Thus, when the MGRP is extended, there is a second repetition pattern during the relaxation period.)

[0022]-[0024].
Claims 5, 6, 8, 17 and 18 are rejected over Li in view of US Pat. Pub. 20240114372 to Min Xu et al. (hereinafter Xu)
Regarding claim 5, Li does NOT teach “The method of Claim 1, wherein at least one of the first measurement time and the second measurement time excludes at least one guard window during a time of remaining satellite coverage.”
In the analogous art of 3GPP Xu teaches “wherein at least one of the first measurement time and the second measurement time excludes at least one guard window during a time of remaining satellite coverage.” (Xu teaches in paras. [0090]-[0109] that measurements exclude a duration where cell quality of network coverage is below a threshold. The coverage information according to para. [0090] may be based on satellite ephemeris data. Para. [0093] teaches “The UE may start a first timer when it enters the coverage area with the cell quality being below the first threshold” Examiner interprets that timer and threshold as a guard window during a remaining satellite coverage.)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Xu with Li to teach measurements of reference signals. Each of Li and Xu are related to wireless communications. One of ordinary skill in the art would have been motivated to combine Li with Xu in order to support discontinuous coverage or variable coverage of networks, such as LEO satellites as taught in Xu paras.

In the analogous art of 3GPP 5G wireless communications, Xu teaches “wherein the first measurement procedure includes measuring satellite signals on a first number of beams and the second measurement procedure includes measuring satellite signals on a second number of beams.” (Xu para. [0097] teaches that the number of beams measured may be lower during a relaxed measurement period. “ If the UE is configured with DRX and DRX cycle in use is longer than N ms (or alternatively equal or larger), and the UE mobility state is determined as low or stationary, then the UE may apply extended relaxation for RRM measurements when measurements are performed in non-active time (when DRX is used). If UE is using RX beamforming, the scaling is applied per antenna panel/beam (all panels, only one panel, or subset of panels or beams) used for RRM measurements.”)
