Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Several configurations are supported to enable a variety of deployments (e.g., indoor, outdoor, sub-6 GHz, mmW). In addition, beam sweeping is supported for PRS to support PRS beam operation. The following table illustrates various types of reference signals that can be used for various positioning methods supported in NR.).
Regarding claim 32, Manolakos teaches: wherein the information comprising the indication comprises a further indication of a purpose of the positioning reference signals, and wherein the indicated purpose of the positioning reference signals is for at least one of an accuracy, latency, or a complexity associated with the positioning reference signals ([0084] RTT and multi-RTT methods can be combined with other positioning techniques, such as UL-AoA and DL-AoD, to improve location accuracy.).

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.
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 35 and 42 are rejected under 35 U.S.C. 103 as being unpatentable over Manolakos in view of Non-patent Literature entitled, “Summary on agenda item 8.11.4 on on-demand PRS” (hereinafter “R2”).
Regarding claim 35, Manolakos does not specifically teach: wherein the indication for positioning reference signals comprises a request for on-demand positioning reference signals.
However, in the same field of endeavor, R2-2106467 teaches: wherein the indication for positioning reference signals comprises a request for on-demand positioning reference signals (p. 5/11).
Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Manolakos to include the feature of on-demand PRS and a combination of Manolakos with R2 renders the claim prima facie obvious within the described scope of the prior art and any indicated differences within the level of one of ordinary skill in the art (e.g., telecommunications engineer) according to a combination of known prior art elements with known methods to yield predictable results. MPEP 2143(I)(A) (e.g., providing on-demand PRS in gapless configuration).
Regarding claim 42, Manolakos does not specifically teach: wherein the indication for positioning reference signals comprises a request for on-demand positioning reference signals.
However, in the same field of endeavor, R2-2106467 teaches: wherein the indication for positioning reference signals comprises a request for on-demand positioning reference signals (p. 5/11).
Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Manolakos to include the feature of on-demand PRS and a combination of Manolakos with R2 renders the claim prima facie obvious within the described scope of the prior art and any indicated differences within the level of one of ordinary skill in the art (e.g., telecommunications engineer) according to a combination of known prior art elements with known methods to yield predictable results. MPEP 2143(I)(A) (e.g., providing on-demand PRS in gapless configuration).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
