Office Action

§103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on 01/08/2024, was filed with the instant application on 01/08/2024. The submission is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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. The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. 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 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou et al (US 2021/0345410 A1), hereinafter, “Zhou” in view of Lei et al (US 2023/0044766 A1), hereinafter, “Lei” further in view of Su et al (US 2020/0288408 A1), hereinafter, “Su” further in view of R2-2109443 et al (3GPP TSG-RAN WG2 Meeting #116-electronic; Online, November 1st - November 12th, 2021; Agenda item: 8.19.2; Source: vivo; Title: Further Discussion on RAN2 Impacts of Msg3 Repetition; Document for: Discussion and Decision), hereinafter, “R2-219443”. Regarding claim 1, Zhou discloses: A method performed by a wireless device, the method (Zhou: fig 30, para [0037], where, a method for wireless communications by a UE performing random access procedure); comprising: receiving, from a base station, a system information block 1 (SIB I) (Zhou: fig 11A-B and fig 12A-B, para [0150], where, the UE may receive SIB1 from the base station), wherein the SIB1 comprises (Zhou: fig 11A-B and fig 12A-B, para [0150], where, “The SIB1 may contain information needed by the UE to access the cell”) a first threshold value and a second threshold value (Zhou: fig 13A-B, para [0150] and [0181], where, the information corresponding to RACH parameters may indicate one or more thresholds such as first threshold and second threshold value to determine reference signal e.g., SSB and/or CSI-RS, para [0182]-[0183]); and performing based on the first threshold and the second threshold: a first type random access in a normal uplink (Zhou: fig 13A-B, para [0181], where, “The one or more RACH parameters may indicate one or more thresholds (may be first threshold and second threshold) based on which the UE may determine at least one reference signal (e.g., an SSB and/or CSI-RS) and/or an uplink carrier (e.g., a normal uplink (NUL) carrier and/or a supplemental uplink (SUL) carrier)” and para [0296], where, “the one or more RRC messages may comprise first RACH parameters for a first RA procedure on a first uplink carrier (e.g., a NUL)”); Zhou does not explicitly teach: a second type random access in the normal uplink, the first type random access in a supplementary uplink or the second type random access in the supplementary uplink, Lei teaches: a second type random access in the normal uplink (Lei: fig 8, para [0089], where, “the second type of RACH message can be transmitted on a regular (e.g., normal) or a supplementary uplink carrier signaled by the PDCCH”), the first type random access in a supplementary uplink or the second type random access in the supplementary uplink (Lei: fig 12, para [0131], “where the first type of RACH message or the second type of RACH message can be transmitted on a regular (e.g., normal) or a supplementary uplink carrier signaled by the PDCCH”); wherein in the first type random access: first transmission of a Msg3 is performed based on a random access response (RAR) (Lei: fig 5, step 530, para [0061], where, “At 530, in response to the RAR message, UE 104 transmits a third message (MSG3) to the BS 102 on the physical uplink shared channel (PUSCH)”); Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date of the invention to use “a second type random access in the normal uplink, the first type random access in a supplementary uplink or the second type random access in the supplementary uplink” as taught by Lei into Zhou in order to efficiently performing a retransmission of a message 3 in the random access procedure (Lei: para [0008]); and neither Zhou nor Lei explicitly teach: one or more retransmissions of the Msg3 follow based on the RAR, wherein in the second type random access: first transmission of the Msg3 is performed based on the RAR; wherein, in case of the first type random access in the normal uplink and a first parameter for the second offset having been provided, the first offset and the second offset are determined based on: a first parameter for a target power level; and retransmission of the Msg 3 based on the RAR does not follow, wherein transmission power of a physical uplink shared channel (PUSCH) for the Msg 3 is determined based on a sum of a first offset and a second offset. Su teaches: one or more retransmissions of the Msg3 follow based on the RAR, wherein in the second type random access: first transmission of the Msg3 is performed based on the RAR (Su: fig 4, para [0100]-[0103], where, the UE performs Msg3 retransmission based on RAR”, Msg3 transmission is equivalent to first transmission when the UE made the first attempt of the Msg3 transmission); the first parameter for the second offset (Su: fig 4, para [0103], where, “the transmit power of the msg3 and/or the UCI that is determined in the second random access attempt process is referred to as the second transmit power”), wherein, in case of the second type random access in the normal uplink (Su: para [0006], where, “transmit power of a second random access preamble message, the second random access preamble message is a random access preamble message in the second random access attempt”) and the first parameter for the second offset having been provided (Su: fig 4, steps S41-S45, para [0108], where, “the first transmit power is actual transmit power of a first msg3 and/or the “first uplink control message” (equivalent to “first parameter”) (referred to as first UCI in the following). Likewise, the larger one of the transmit power of the second random access preamble message (referred to as a second msg1 in the following) and fourth transmit power may be determined as the second transmit power (equivalent to “second offset”)”) the first offset and the second offset are determined based on: a second parameter for a target power level (Su: fig 4, steps S41-S45, para [0108], where, “the second transmit power (equivalent to “second offset”) is actual transmit power of a second msg3 and/or the second uplink control message (equivalent to “second parameter”) (referred to as second UCI in the following)”); and the first parameter for the second offset (Su: fig 4, para [0103], where, “the transmit power of the msg3 and/or the UCI that is determined in the second random access attempt process is referred to as the second transmit power (equivalent to “second offset”)”), wherein, in case of the first type random access in the supplementary uplink (Su: fig 4, para [0108], where, “the first transmit power is actual transmit power of a first msg3 and/or the first uplink control message (referred to as first UCI in the following)”) and a second parameter for the second offset having been provided (Su: fig 4, para [0108], where, “the second transmit power, and the second transmit power is actual transmit power of a second msg3 and/or the second uplink control message (referred to as second UCI (equivalent to “second parameter”) in the following)”), the first offset (Su: fig 4, para [0108], where, “a first msg3 and/or the first uplink control message (referred to as first UCI in the following)”) and the second offset are determined based on (Su: fig 4, para [0108], where, “the second power control parameter in the second random access attempt, the second transmit power is an actually used transmit power at the time of sending the second msg3 and/or the second UCI”): a third parameter for a target power level (Su: fig 4, para [0009], where, “the third power ramping step is used to determine the transmit power of the second random access preamble message, and the second power ramping step, the second power offset”); and the second parameter for the second offset (Su: fig 4, para [0139], where, “the terminal device determines P1_2 as the second transmit power, and sends the second msg3 or the second UCI by using the second transmit power”), and wherein, in case of the second type random access in the supplementary uplink and the second parameter for the second offset having been provided (Su: fig 4, para [0139], where, “the terminal device determines P1_2 as the second transmit power, and sends the second msg3 or the second UCI by using the second transmit power”), the first offset and the second offset are determined (Su: fig 4, para [0139], where, “the terminal device determines P1_2 as the second transmit power, and sends the second msg3 or the second UCI by using the second transmit power”), based on: a fourth parameter for a target power level (Su: fig 4, para [0110], where, “the fourth transmit power is the transmit power of the second msg3 and/or the second UCI that is calculated based on the second power control parameter in the second random access attempt, the second transmit power is an actually used transmit power at the time of sending the second msg3 and/or the second UCI”); and the second parameter for the second offset (Su: fig 4, para [0108], where, “the first transmit power is actual transmit power of a first msg3 and/or the first uplink control message (referred to as first UCI in the following)”); Therefore, it would have been obvious to one of ordinary skilled in the art before the effective filing date of the invention to use “one or more retransmissions of the Msg3 follow based on the RAR, wherein in the second type random access: first transmission of the Msg3 is performed based on the RAR” as taught by Su into the teaching of Zhou and Lei in order to enabled to increase with the random access attempt quantity (Su: para [0149]); and neither Zhou nor Lei nor Su explicitly teach: retransmission of the Msg 3 based on the RAR does not follow , wherein transmission power of a physical uplink shared channel (PUSCH) for the Msg 3 is determined based on a sum of a first offset and a second offset.
