In one embodiment, the list of candidate frequencies can be generated by obtaining at least one performance metric for each candidate frequency in the list of candidate frequencies and selecting the LTE cell on which to camp based on a set of performance metrics associated with the list of candidate frequencies… Note: Once selected that band becomes the target band].
However, the combination of Su and Kim does not specifically disclose reducing by lowering a network antenna power of the mobile terminal, a network signal strength of the reference network frequency band to the modified network signal strength, the method further comprises: when a GPS stop instruction is received, recovering the network antenna power of the mobile terminal to recover the network signal strength of the reference network frequency band.
In an analogous art, Rao teaches “reducing by lowering a network antenna power of the mobile terminal, a network signal strength of the reference network frequency band to the modified network signal strength” as [(Para. 0030), There are some existing approaches or proposals to mitigate the LTE TX interference to ISM RX (receiver). For example, when LTE TX adjacent interference to ISM RX is higher than a threshold, one could limit or reduce TX transmission power, blank the TX transmission, or even switch the TX frequency to a different band which is farther away from ISM bands.].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Su and Kim to provide an effective technique as taught by Rao for improve concepts for estimating adjacent channel interference for multi-mode devices and provide higher estimation accuracy and does not need to pre-store huge look-up tables in the mitigation interference process [Rao: Para. 0004 and 0088].
However, the combination of Su, Kim and Rao does not specifically disclose the method further comprises: when a GPS stop instruction is received, recovering the network antenna power of the mobile terminal to recover the network signal strength of the reference network frequency band.
In an analogous art, Chao teaches “the method further comprises: when a GPS stop instruction is received, recovering the network antenna power of the mobile terminal to recover the network signal strength of the reference network frequency band” as [(Para. 0039), Accordingly, blocks that may cause second harmonic interference with the GPS receiver by falling entirely into the GPS frequency range (Pi1, Pi2, . . . etc.) are first analyzed to determine if their power is greater than 0 (at 116). If so, power is reduced by stepping down the power of these blocks (at 118).].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Su, Kim and Rao to provide an effective technique as taught by Chao for reducing harmonic interference between broadband wireless devices and GPS receivers [Chao: Para. 0004].
Regarding claim 17, the combination of Su, Kim and Rao, specifically Su teaches “wherein after the determining a target network frequency band corresponding to the mobile terminal” as [(Para. 0021), selecting an LTE cell on which to camp using the list of candidate frequencies for cell acquisition. In one embodiment, the list of candidate frequencies can be generated by obtaining at least one performance metric for each candidate frequency in the list of candidate frequencies and selecting the LTE cell on which to camp based on a set of performance metrics associated with the list of candidate frequencies… Note: Once selected that band becomes the target band] “and controlling the mobile terminal to be registered in the target network frequency band,” [(Para. 0020), The program code can further cause the mobile device to generate a list of candidate frequencies for cell acquisition and select a cell on which to camp … (Para. 0025), cause the mobile station to establish a connection on the legacy network using the first receiver and the transmitter for processing the voice call; determine, during the voice call, a strongest suitable LTE cell of the LTE network using a second receiver of the mobile station based on one or more measured performance metrics; and return to the LTE network by camping on the strongest suitable LTE cell].
However, the combination of Su, Kim and Rao does not specifically disclose the method further comprises: when a GPS stop instruction is received, recovering the network signal strength of the reference network frequency band.
In an analogous art, Chao teaches “the method further comprises: when a GPS stop instruction is received, recovering the network signal strength of the reference network frequency band” as [(Para. 0005), reducing the transmit power level stepwise for the second plurality of frequency blocks until valid GPS data is determined or until the transmit power level for the second plurality of frequency blocks is zero].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Su, Kim and Rao to provide an effective technique as taught by Chao for reducing harmonic interference between broadband wireless devices and GPS receivers [Chao: Para. 0004].
Claim 13 is rejected under 35 U.S.C. 103 as being unpatentable over Su in view of Kim, further in view of Rao and further in view of Shilov et al. (Pub. No. 2020/0374861 A1 hereinafter Shilov).
Regarding claim 13, the combination of Su, Kim and Rao, specifically Su teaches “wherein the selecting the target network frequency band among the plurality of candidate network frequency bands according to the modified network signal strength comprises: comparing the obtained each network signal strength with the modified network signal strength to select at least one candidate network frequency band having a network signal strength greater than the modified network signal strength;” (Para. 0020), The program code can further cause the mobile device to generate a list of candidate frequencies for cell acquisition… (Para. 0021), obtaining at least one performance metric for each candidate frequency… (Para. 0021), The at least one performance metric includes a signal strength or a signal quality.] “and when the plurality of candidate network frequency bands corresponding to a maximum network signal strength is greater than 1” [(Para. 0021), The method can further include selecting the LTE cell using the candidate frequency in the list of candidate frequencies having a highest value for the signal strength or the signal quality.].
However, the combination of Su, Kim and Rao does not specifically disclose randomly selecting a candidate network frequency band as the target network frequency band from the number of candidate network frequency bands corresponding to the maximum network signal strength.
In an analogous art, Shilov teaches “randomly selecting a candidate network frequency band as the target network frequency band from the number of candidate network frequency bands corresponding to the maximum network signal strength” as [(Para. 0080), When selecting MCR tentative candidate resources for transmission UE prioritizes selection of at least one earliest in time candidate resource among MCS-EIT earliest in time resources (MCS-EIT<MCS) in order to announce its scheduling decision by PSCCH as soon as possible. Other resources may be selected randomly.].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Su, Kim and Rao to provide an effective technique as taught by Shilov for improve NR V2X sidelink by efficient resource selection and/or reselection procedure suitable for periodic and aperiodic traffic communications [Shilov: Para. 0003-0004].
