Regarding Claim 53, see similar rejection to Claim 2. Claim Rejections - 35 USC § 103 8. 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 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. 8.1. 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. 8.2. 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. 8.3. Claim(s) 7, 48 is/are rejected under 35 U.S.C. 103 as being unpatentable over by Zhang et al., (“Zhang”, US 2023/0209606 A1) in view of Shrestha et al., (“Shrestha”, US 2023/0094907 A1). Regarding Claim 7, Zhang teaches, The RA method according to claim 6. Zhang does not expressly teach wherein the start position of the RAR window (1004) is separated from the end position of the second RO (402d) by at least one time unit, but Shrestha teaches wherein the start position of the RAR window is separated from the end position of the second RO by at least one time unit (Shrestha, FIG.1, UE 104, [0027], FIG.7, S702, [0057]: The first timing offset parameter may specified as a minimum gap used between the transmission of the last repetition of the preamble and the start position of the RAR window to maintain synchronization between the UE and network., S706, [0059]: the UE 104 may monitor for a RAR within a RAR window with a start position determined based at least in part on a RA occasion (e.g., the RA occasion used at step 704), the first timing offset parameter. For example, the RAR window may start at the subframe (or slot) that includes the end of the preamble transmission or last preamble repetition (at step 704) plus X′ subframes (or slots)). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to perform RA method as taught by Zhang, to determine the start position of the RAR window is separated from the end position of the last RO by at least one time unit, as taught by Shrestha. Doing so provides a method to perform a RA method and the determination of start position of the RAR window is separated from the end position of the second RO by at least one time unit (Shrestha, FIG.7, [0057-59]). Regarding Claim 48, see similar rejection to Claim 7. 8.4. Claim(s) 42 is/are rejected under 35 U.S.C. 103 as being unpatentable over by Zhang et al., (“Zhang”, US 2023/0209606 A1) in view of Shrestha et al., (“Shrestha”, US 2023/0094907 A1), and further in view of Xiong et al., (“Xiong”, US 2020/0374928 A1). Regarding Claim 42, Zhang-Shrestha teaches, The RA method according to of claim 7 Zhang-Shrestha does not expressly teaches wherein the start position of the RAR window is determined based on a second CSS, and the second CSS is a Type1-CSS corresponding to a downlink reference signal associated with the second RO, but Xiong teaches wherein the start position of the RAR window is determined based on a second CSS, and the second CSS is a Type1-CSS corresponding to a downlink reference signal associated with the second RO (Xiong, [0028-29]: the RAR window starts at the first symbol of the earliest COntrol REsource SET (CORESET) on which the UE is configured to receive Physical Downlink Control Channel (PDCCH) for Type 1-PDCCH Common Search Space (CSS) set, that is at least one symbol after the last symbol of the PRACH occasion corresponding to the PRACH transmission. The symbol duration may correspond to the subcarrier spacing (SCS) for Type 1-PDCCH CSS set). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to perform RA method as taught by Zhang-Shrestha, to determine wherein the start position of the RAR window is separated from the end position of the second RO by at least one time unit, as taught by Xiong. Doing so provides a method to perform a RA method and the determination of start position of the RAR window is separated from the end position of the second RO by at least one time unit (Xiong, [0028-29]). 8.5. Claim(s) 12-13, 49-50 is/are rejected under 35 U.S.C. 103 as being unpatentable over by Zhang et al., (“Zhang”, US 2023/0209606 A1) in view of Xiong et al., (“Xiong”, US 2020/0374928 A1). Regarding Claim 12, Zhang teaches, The RA method according to of claim 6. Zhang does not expressly teach wherein the start position of the RAR window (1004) is determined based on a second CSS, and the second CSS is a Type1-CSS corresponding to a downlink reference signal associated with the second RO (402d), but Xiong teaches wherein the start position of the RAR window is determined based on a second CSS, and the second CSS is a Type1-CSS corresponding to a downlink reference signal associated with the second RO (Xiong, [0028-29]: the RAR window starts at the first symbol of the earliest COntrol REsource SET (CORESET) on which the UE is configured to receive Physical Downlink Control Channel (PDCCH) for Type 1-PDCCH Common Search Space (CSS) set, that is at least one symbol after the last symbol of the PRACH occasion corresponding to the PRACH transmission. The symbol duration may correspond to the subcarrier spacing (SCS) for Type 1-PDCCH CSS set). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to perform RA method as taught by Zhang, to determine wherein the start position of the RAR window is separated from the end position of the second RO by at least one time unit, as taught by Xiong. Doing so provides a method to perform a RA method and the determination of start position of the RAR window is separated from the end position of the second RO by at least one time unit (Xiong, [0028-29]). Regarding Claim 13, Zhang teaches, The RA method according to claim 12, wherein the start position of the RAR window is a first monitoring position (Zhang, [0043]: The RAR window may begin (“start position”) after a last RO (402d) (“2nd RO) of the multiple ROs). Zhang does not expressly teach a first monitoring position of the second CSS. Xiong teaches (Xiong, [0028-29]: the RAR window starts at the first symbol of the earliest COntrol REsource SET (CORESET) on which the UE is configured to receive Physical Downlink Control Channel (PDCCH) for Type 1-PDCCH Common Search Space (CSS) set, that is at least one symbol after the last symbol of the PRACH occasion corresponding to the PRACH transmission. The symbol duration may correspond to the subcarrier spacing (SCS) for Type 1-PDCCH CSS set). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to determine the start position of the RAR window as taught by Zhang, to begin monitoring for a RAR starts at the first position of the second CSS as taught by Xiong. Doing so provides a method to determine the start position of the RAR window is a first monitoring position of the second CSS (Xiong, [0028-29]). Regarding Claims 49-50 see similar rejection to Claims 12-13 respectively. Conclusion 9. The prior art made of record and not relied upon is considered pertinent to applicant’s disclosure. Turtinen et al., US 2022/0159728 A1, Method For Indication Of Random Access Response Transmission In Long Term Evolution System, Involves Providing Random Access Channel Occasion (RO) To Lower Layer And Receiving Indication Of RO From Lower Layer Succeeding Listen Before Talk. 10.
