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 of this title, 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.
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.
Claim 11 is rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. (CN 110087296 A, of IDS, translated with family US 20200336986 A1, hereinafter ‘CHEN’) in view of Choi et al (US 20210274449 A1, of IDS, hereinafter ‘CHOI’).
Regarding claim 11, CHEN teaches the method according to claim 1.
CHEN does not explicitly disclose wherein the power adjustment value is to adjust an upper limit, a lower limit, and/or an average value of the downlink transmit power; or,
wherein at least one granularity is used in the power adjustment command to indicate the power adjustment value.
In an analogous art, CHOI teaches wherein the power adjustment value is to adjust an upper limit, a lower limit, and/or an average value of the downlink transmit power; or,
wherein at least one granularity is used in the power adjustment command to indicate the power adjustment value (

[0097] FIG. 5 is a diagram of the first embodiment for protecting an access uplink from a terminal in IAB, according to an embodiment.
[0098] Referring to a reference numeral 501 of FIG. 5, a maximum value P.sub.max of transmit power of a backhaul downlink (411 of FIG. 4) may be down-adjusted to a certain value A so as to match receive power of the backhaul downlink (411 of FIG. 4) to receive power of an access uplink (415 of FIG. 4). A may be a value within a certain range (for example, 23 dBm≤A≤24 dBm) or a certain value (for example, A=24 dBm). …… Alternatively, the certain value may be determined to be the receive power of the access uplink signal from the UE 404 or a value equal to or less than the receive power of the access uplink signal. Also, the certain range may be determined to be a range within x dBm from the receive power of the access uplink signal from the UE 404 or within x dBm from the maximum transmit power capable of transmitting the signal by the UE 404. ).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to take the technique of using power limits within a upper or lower value or a dBm granularity for controlling transmission power for wireless communication system of CHOI to the power control method for wireless communications of CHEN in order to take the advantage of a method for matching receive power of an access uplink so as to guarantee data reception performance of the access uplink in an IAB node reducing interference (CHOI: [0007, 0096]).

sending, by the child node to the parent node, the power adjustment command carrying the sequence number corresponding to the power adjustment value; or,
wherein in a case of a carrier aggregation, the power adjustment command comprises a power adjustment value corresponding to each aggregated carrier, and the power adjustment value corresponding to each aggregated carrier is arranged based on a sequence number of each aggregated carrier.
In an analogous art, XI teaches wherein the sending, by the child node, a power adjustment command to the parent node comprises:
sending, by the child node, a plurality of power adjustment commands to the parent node, wherein a sum of values indicated in the plurality of power adjustment commands is the power adjustment value; or,
wherein the sending, by the child node, a power adjustment command to the parent node comprises:
determining, by the child node based on a preset table, a sequence number corresponding to the power adjustment value, wherein the table comprises a plurality of correspondences, and the correspondences are correspondences between power adjustment values and sequence numbers; and
sending, by the child node to the parent node, the power adjustment command carrying the sequence number corresponding to the power adjustment value (
[0095] transmission power of CSI-RS or SS blocks may be changed or adapted for inter-cell interference coordination, interference mitigation, flexible cell coverage, or the like.
[00161] FIG. 12 is an example 1200 of another configuration of a measurement and reporting setting for unified BM with joint and independent beam reporting of a CSI-RS and a SS block. ….. In example 1200, since Resource Setting 1 contains periodic RSs, either aperiodic reporting or periodic reporting may be utilized.
[00170] In UBR 3, a full expression of a measurement result may comprise fields for RS type, such as 1 or 2 bits, and variable length of measurement quantities for different RSs and associated values. The length of measurement quantities for different RSs may be similar or different depending on reporting overhead, accuracy, L1-RSRP resolution, L1-RSRP step size, a maximal L1-RSRP range, or the like. An example of beam reporting is shown in Table 10. For example, when the measurement quantity is 001101, the first two bits of 00 may indicate the SS block beam and four bits 1101 may be utilized for a range of SS block L1-RSRP values. In another example, when the measurement quantity is 011000101 , the first two bits of 01 may indicate a CSI- RS beam and 7 bits 1000101 may be utilized for a large range of CSI-RS L1-RSRP values.

(It is obvious that the Measurement quantity in Table 10 represents a sequence number in a preset Table configured for digital value representation for Reference Signal measurement values equivalent to power adjustment value considering possible range of values, step size or granularity, and the sequence number corresponding the Measurement quantity being reported/sent by the WTRU or the child node to gNB or parent node)); or,
wherein in a case of a carrier aggregation, the power adjustment command comprises a power adjustment value corresponding to each aggregated carrier, and the power adjustment value corresponding to each aggregated carrier is arranged based on a sequence number of each aggregated carrier.
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to take the technique of reporting measurement values using variable length of measurement quantities for different RSs for wireless communication system of XI to the power control method for wireless communications of CHEN in order to take the advantage of a method for reporting accuracy, resolution, step size, a maximal range of reference signal measurement for interference coordination and mitigation (XI: [0095, 00170]).
Regarding claim 19, the claim is interpreted and rejected for the same reason as set forth for claim 12.
