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:

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.
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.
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.
Claims 14-17 are rejected under 35 U.S.C. 103 as being unpatentable over Liao et al. (US 2023/0146553 A1) in view of Hou et al. (US 2024/0147421 A1).
Consider claims 14 and 16, and as applied to claim 13 above, Liao et al. fail to disclose wherein the configuration information configures the DLRS in a same downlink bandwidth part (BWP) as a downlink BWP associated with the PEI communication (claim 14) and wherein the DLRS is associated with at least one of UE synchronization, automatic gain control adjustment, channel estimation, or presence detection of the PEI communication (claim 16).
In the same field of endeavor, Hou et al. disclose sending configuration information that configures a reference signal (i.e., DLRS) in a same downlink bandwidth part (BWP) as a downlink BWP associated with the PEI communication (claim 14 - see, for example, abstract, figure 2, and paragraph 0121) and wherein the reference signal (i.e., DLRS) is associated with at least one of UE synchronization (claim 16 – see paragraphs 0116 and 0126 – reference signal is used for time and/or frequency synchronization), automatic gain control adjustment, channel estimation, or presence detection of the PEI communication.
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 configure the DLRS in the same downlink BWP as the downlink BWP of the PEI communication as disclosed by Hou et al. in the UE disclosed by Liao et al. in order to allow the UE to perform synchronization without bandwidth switching and thus maintain low power consumption (see, for example, paragraph 0121 of Huo et al.).
Consider claim 15, and as applied to claim 13 above, Liao et al. fail to specifically disclose wherein the DLRS is quasi co-located with the PEI communication.
In the same field of endeavor, Hou et al. disclose that the reference signal (i.e., DLRS in the form of an SSB) is quasi co-located with the PEI communication (see figures 4, 6, and 8 and paragraphs 0116, 0168, and 0185 – SSB is in the same BWP as the PEI communication).
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 locate the DLRS in the same downlink BWP as the downlink BWP of the PEI communication as disclosed by Hou et al. in the UE disclosed by Liao et al. in order to allow the UE to perform synchronization without bandwidth switching and thus maintain low power consumption (see, for example, paragraph 0121 of Huo et al.).
Consider claim 17, and as applied to claim 13 above, Liao et al. fail to disclose the one or more processors are further configured, individually or collectively, to:
detect a presence of the DLRS in a PEI occasion associated with the PEI communication;
and
receive the PEI communication in the PEI occasion based at least in part on detecting the
DLRS.
In the same field of endeavor, Hou et al. disclose wherein the one or more processors (figure 10 – processor 1020) are further configured, individually or collectively, to: detect a presence of the DLRS in a PEI occasion associated with the PEI communication and receive the PEI communication in the PEI occasion based at least in part on detecting the DLRS (terminal device detects the reference signal and receives the paging early indication information based on the detecting in the same BWP – see paragraphs 0016 and 0126).
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 receive the PEI communication based on the detecting of the reference signal as disclosed by Huo et al. in the UE disclosed by Liao et al. in order to perform time and/or frequency synchronization with the network device and detect the paging early indication information without bandwidth switching and thus maintain low power consumption (see, for example, paragraph 0126 of Huo et al.).
Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Liao et al. (US 2023/0146553 A1) in view of Lin (US 2022/0271878 A1).
Consider claim 18, and as applied to claim 13 above, Liao et al. fail to specifically disclose wherein the configuration information indicates that the UE is to monitor PEI occasions for the DLRS.
In the same field of endeavor, Lin discloses that the UE receives configuration information for references signal (RS) based PEI and the UE monitors PEI occasions for the RS based on the configuration (see, for example, figures 7 and 8 and paragraphs 0121-0124 and 0155).
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 monitor for a RS in PEI occasions as disclosed by Lin in the UE disclosed by Liao et al. in order to conserve power.
Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Liao et al. (US 2023/0146553 A1) in view of Reial et al. (US 2024/0381307 A1).
Consider claim 21, and as applied to claim 19 above, Liao et al. fail to disclose wherein the one or more processors, to identify whether the PEI communication includes the TRS availability indication field, are configured, individually or collectively, to identify whether the PEI communication includes the TRS availability indication field by performing a hypothesis testing procedure.
In the same field of endeavor, Reial et al. disclose wherein the one or more processors (processing circuitry 84/processor 86 – figure 2), to identify whether the PEI communication includes the TRS availability indication field, are configured, individually or collectively, to identify whether the PEI communication includes the TRS availability indication field by performing a hypothesis testing procedure (see paragraphs 0091, 0093, 0147, and claim 23 - the processing circuitry is configured to identify the particular instance of additional information associated with the received TRS conveying the PEI by performing hypothesis testing based on the set of possible instances of additional information).
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 perform a hypothesis testing procedure to identify the TRS in the PEI communication as disclosed by Reial et al. in the UE disclosed by Liao et al. in order to properly identify a particular instance of field of additional information (see, for example, paragraph 0093 of Reial et al.).
