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.
Claim(s) 3-5 and 11-17 are rejected under 35 U.S.C. 103 as being unpatentable over Wu et al (US Patent No. 12,348,287 B2) in view of Cheng et al (US Publication No. 2021/0105761 A1).
With respect to claim 3, Wu discloses the claimed subject matter as discussed above except further comprising one of: determining the service time of the serving satellite according to ephemeris data corresponding to the serving satellite; or determining the service time of the serving satellite according to second indication information.
However, Cheng teaches further comprising one of: determining the service time of the serving satellite according to ephemeris data corresponding to the serving satellite; or determining the service time of the serving satellite according to second indication information (paragraph 0124; 0200 disclose Koffset can be derived by UE (calculated based on UE location, e.g., GNSS, and satellite ephemeris; a UE can predict TA based on its location and/or satellite ephemeris) in order to provide a timing offset for UL transmission (Abstract). Therefore, based on Wu in view of Cheng, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to utilize the teaching of Cheng to the system of Wu in order to provide a timing offset for UL transmission.
With respect to claim 4, Wu discloses the claimed subject matter as discussed above except wherein the first indication information comprises delay information k, and sending the predicted CSI to the network device at the first feedback moment comprises: determining predicted CSI at a moment t+k, wherein t is the first feedback moment, and t and k are positive numbers; and at the moment t, sending the predicted CSI at the moment t+k to the network device.
However, Cheng teaches wherein the first indication information comprises delay information k (paragraph 0072 disclose processing delay in the NTN), and sending the predicted CSI to the network device at the first feedback moment comprises: determining predicted CSI at a moment t+k, wherein t is the first feedback moment, and t and k are positive numbers; and at the moment t, sending the predicted CSI at the moment t+k to the network device (paragraph 0009, 0010; 0143 disclose UL transmission including CSI.

However, Cheng teaches wherein the first indication information comprises delay information k (paragraph 0072 disclose processing delay in the NTN), and sending the predicted CSI to the network device at the first feedback moment comprises: determining predicted CSI from a moment t+k-m to a moment t+k, wherein t is the first feedback moment, m is a time length corresponding to the predicted CSI, and t, k, and m are positive numbers; and at the moment t, sending the predicted CSI from the moment t+k-m to the moment t+k to the network device (paragraph 0009, 0010; 0143 disclose UL transmission including CSI. The CSI on the PUSCH is transmitted on slotn.Math.2.sup.μ.sup.PUCCH.sup.−μ.sup.PDCCH┘+K.sub.1+K.sub.offset, the PDCCH reception ending in slot n, μ.sub.PUSCH being a subcarrier spacing of the PUSCH, μ.sub.PDCCH being a subcarrier spacing of the PDCCH, K being an offset value indicated in the DCI, and Koffset being an additional offset value for compensating a required timing advance (TA) and a processing delay for operation in the NTN) in order to provide a timing offset for UL transmission (Abstract). Therefore, based on Wu in view of Cheng, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to utilize the teaching of Cheng to the system of Wu in order to provide a timing offset for UL transmission.
With respect to claim 11 Wu discloses the claimed subject matter as discussed above except further comprising one of: determining the first feedback moment according to a service time of a serving satellite; or determining the first feedback moment according to an agreement.

Therefore, based on Wu in view of Cheng, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to utilize the teaching of Cheng to the system of Wu in order to provide a timing offset for UL transmission.
With respect to claim 12, Wu teaches further comprising: sending first indication information, wherein the first indication information indicates the first feedback moment (col. 2, lines 39-65; col. 7, lines 16-43 disclose reporting differential CSI feedback according to the first configuration, the first configuration includes at least an indication of when the UE is to report differential CSI feedback).

Therefore, based on Wu in view of Cheng, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to utilize the teaching of Cheng to the system of Wu in order to provide a timing offset for UL transmission.
With respect to claim 14, Wu teaches wherein the first indication information comprises at least one of: a number of reporting of the CSI; a reporting cycle of the CSI; a reporting moment of the CSI; or delay information (col. 18, lines 5-19 disclose each CSI feedback reported by the UE in a given CSI feedback stage may depend in part on a previous CSI feedback reported by the UE in a previous CSI feedback stage. Each CSI feedback stage may occur at a different point in time).
With respect to claim 15, Wu teaches further comprising one of: sending a radio resource control (RRC) message, wherein the RRC message comprises the first indication information (col. 22, lines 14-24 disclose the UE receiving (e.g., via RRC signaling, downlink control information (DCI) signaling, etc.) a configuration for reporting differential CSI feedback); sending a medium access control (MAC) control element (CE), wherein the MAC CE comprises the first indication information; or sending downlink control information (DCI), wherein the DCI comprises the first indication information (col. 22, lines 14-24 disclose the UE receiving (e.g., via RRC signaling, downlink control information (DCI) signaling, etc.) a configuration for reporting differential CSI feedback).
