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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 1/06/2025 has been entered. Response to Arguments Applicant’s Argument: Applicant argues the combination of applied references fail teach “wherein the dynamic PRACH configuration message defines an applicable time period for the dynamic PRACH configuration” and "selecting the dynamic PRACH configuration when the dynamic configuration message indicates that the dynamic PRACH configuration is applicable based on a current time being within the defined applicable time period for the dynamic PRACH configuration” as recited in amended independent claim 1. Xu does not define an applicable time in the configuration information. Examiner’s Response: Applicant’s arguments with respect to claim(s) 1 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant has amended the claim to overcome the previous grounds of rejection. A new search was conducted and a new reference is applied. 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 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 1, 6 - 8, 11-12, 17 - 19, 21-22, 27 - 28, and 30 are rejected under 35 U.S.C. 103 as being unpatentable over Wu et al. (“Wu”) (US 20220061089 A1) in view of Yoo et al. (“Yoo”) (US 20190159244 A1). Regarding Claim 1, Wu teaches: A method of wireless communication, comprising: receiving, at a user equipment (UE), a dynamic configuration message including a physical random access channel (PRACH) configuration update [¶0136, ¶0143 DCI indicates dynamic RACH allocation information, ¶0150, periodically update the RACH resource configuration corresponding to dynamic configuration message with PRACH update] including resources, a number of random access preambles, a number of contention-based preambles, or a number of synchronization signal blocks (SSB) per RACH occasion for a dynamic PRACH configuration [¶0143 resource dynamically allocated by DCI], wherein the dynamic configuration message is one of a physical control message or a paging message [¶0143 control message i.e. DCI], wherein the dynamic PRACH configuration message defines an applicable time period for the dynamic PRACH configuration [¶0143, “a RACH resource dynamically allocated by the base station by using the DCI may be valid in a current COT, or may be valid in one or several subsequent COTs. A valid time may be agreed upon in advance in a standard protocol, or may be indicated in DCI.”]; selecting the dynamic PRACH configuration when the dynamic configuration message indicates that the dynamic PRACH configuration is applicable based on a current time being within the defined applicable time period for the dynamic PRACH configuration [¶0136-143, DCI dynamically indicates PRACH resource, valid during a COT as in ¶0143, and obtained as in ¶0147 by terminal corresponding to “selecting”]; and transmitting a first message of a RACH procedure based on the dynamic PRACH configuration [¶0170, Figure 2, S202, terminal transmits message based on RACH procedure as indicated in S201, Figure 2, ¶0111]. Wu teaches L1 signaling on a control channel indicating RACH configuration but does not expressly teach DCI for number of RACH occasions however Yoo teaches DCI, and the PRACH configuration update including a number of random access (RACH) occasions in a frequency domain [¶0099, DCI indicates frequency resources for RACH which corresponds to “number of RACH occasions in a frequency domain” as per Applicant’s specification [0077]]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to specify DCI indicating frequency resources for the RACH configuration. Xu teaches L1 signaling which is known to be on a physical control channel, thus would comprise DCI, and indicates resources. It would have been obvious to specify indicating frequency resources for RACH in the DCI as in Yoo in order that the terminal knows RACH resources in the frequency axis ¶0099. Regarding (Currently Amended) claim 12, Wu teaches: A method of wireless communication, comprising: transmitting a dynamic configuration message including a physical random access channel (PRACH) configuration update [¶0136, ¶0143 DCI indicates dynamic RACH allocation information, ¶0150, periodically update the RACH resource configuration corresponding to dynamic configuration message with PRACH update] wherein the PRACH configuration update includes resources, a number of random access preambles, a number of contention-based preambles, or a number of synchronization signal blocks (SSB) per RACH occasion for a dynamic PRACH configuration [¶0143 RACH resources dynamically allocated by DCI], wherein the dynamic configuration message is one of a physical control message or a paging message [¶0143 control message i.e. DCI], wherein the dynamic PRACH configuration message defines an applicable time period for the dynamic PRACH configuration [¶0143, “a RACH resource dynamically allocated by the base station by using the DCI may be valid in a current COT, or may be valid in one or several subsequent COTs. A valid time may be agreed upon in advance in a standard protocol, or may be indicated in DCI.”]; and receiving a first message of a RACH procedure based on the dynamic PRACH configuration during the defined applicable time period for the defined PRACH configuration [¶0136-143, DCI dynamically indicates RACH resource, valid during a COT as in ¶0143, and obtained as in ¶0147 by terminal, and ¶0170, Figure 2, S202, terminal transmits message based on RACH procedure as indicated in S201, Figure 2, ¶0111 thus based on configuration] Xu teaches L1 signaling on a control channel indicating RACH configuration but does not expressly teach DCI for number of RACH occasions however Yoo teaches DCI, and the PRACH configuration update including a number of random access (RACH) occasions in a frequency domain [¶0099, DCI indicates frequency resources for RACH which corresponds to “number of RACH occasions in a frequency domain” as per Applicant’s specification [0077]]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to specify DCI indicating frequency resources for the RACH configuration. Xu teaches L1 signaling which is known to be on a physical control channel, thus would comprise DCI, and indicates resources. It would have been obvious to specify indicating frequency resources for RACH in the DCI as in Yoo in order that the terminal knows RACH resources in the frequency axis ¶0099. Regarding (Currently Amended) claim 22, Wu teaches: An apparatus for wireless communication at a user equipment (UE), comprising: one or more memories, individually or in combination, storing computer-executable instructions; and one or more processors coupled with the memory and, individually or in combination, configured to execute the computer-executable instructions [Figure 1 terminal] to: receive a dynamic configuration message including a physical random access channel (PRACH) configuration update [¶0136, 0143 DCI indicates dynamic RACH allocation information, ¶0150, periodically update the RACH resource configuration corresponding to dynamic configuration message with PRACH update] including resources, a number of random access preambles, a number of contention-based preambles, or a number of synchronization signal blocks (SSB) per RACH occasion for a dynamic PRACH configuration [¶0143 resource dynamically allocated by DCI], wherein the dynamic configuration message is one of a physical control message or a paging message [¶0143 control message i.e. DCI], wherein the dynamic PRACH configuration message defines an applicable time period for the dynamic PRACH configuration [¶0143, “a RACH resource dynamically allocated by the base station by using the DCI may be valid in a current COT, or may be valid in one or several subsequent COTs. A valid time may be agreed upon in advance in a standard protocol, or may be indicated in DCI.”]; select the dynamic PRACH configuration when the dynamic configuration message indicates that the dynamic PRACH configuration is applicable based on a current time being within the defined applicable time period for the dynamic PRACH configuration [¶0136-143, DCI dynamically indicates PRACH resource, valid during a COT as in ¶0143, and obtained as in ¶0147 by terminal corresponding to “selecting”]; and transmit a first message of a RACH procedure based on the dynamic PRACH configuration [¶0170, Figure 2, S202, terminal transmits message based on RACH procedure as indicated in S201, Figure 2, ¶0111]. Wu teaches L1 signaling on a control channel indicating RACH configuration but does not expressly teach DCI for number of RACH occasions however Yoo teaches DCI, and the PRACH configuration update including a number of random access (RACH) occasions in a frequency domain [¶0099, DCI indicates frequency resources for RACH which corresponds to “number of RACH occasions in a frequency domain” as per Applicant’s specification [0077]]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to specify DCI indicating frequency resources for the RACH configuration. Xu teaches L1 signaling which is known to be on a physical control channel, thus would comprise DCI, and indicates resources. It would have been obvious to specify indicating frequency resources for RACH in the DCI as in Yoo in order that the terminal knows RACH resources in the frequency axis ¶0099. Regarding (Currently Amended) claim 30, Wu teaches: An apparatus for wireless communication, comprising: one or more memories, individually or in combination, storing computer-executable instructions; and one or more processors coupled with the memory and, individually or in combination, configured to execute the computer-executable instructions [Figure 1 base station] to: transmit a dynamic configuration message including a physical random access channel (PRACH) configuration update [¶0136, ¶0143 DCI indicates dynamic RACH allocation information, ¶0150, periodically update the RACH resource configuration corresponding to dynamic configuration message with PRACH update] wherein the PRACH configuration update includes resources, a number of random access preambles, a number of contention-based preambles, or a number of synchronization signal blocks (SSB) per RACH occasion for a dynamic PRACH configuration [¶0143 resource dynamically allocated by DCI], wherein the dynamic configuration message is one of a physical control message or a paging message [¶0143 control message i.e. DCI], wherein the dynamic PRACH configuration message defines an applicable time period for the dynamic PRACH configuration [¶0143, “a RACH resource dynamically allocated by the base station by using the DCI may be valid in a current COT, or may be valid in one or several subsequent COTs. A valid time may be agreed upon in advance in a standard protocol, or may be indicated in DCI.”]; and receive a first message of a RACH procedure based on the dynamic PRACH configuration during the defined applicable time period for the defined PRACH configuration [¶0136-143, DCI dynamically indicates PRACH resource, valid during a COT as in ¶0143, and obtained as in ¶0147 by terminal, and ¶0170, Figure 2, S202, terminal transmits message based on RACH procedure as indicated in S201, Figure 2, ¶0111 thus based on configuration] Xu teaches L1 signaling on a control channel indicating RACH configuration but does not expressly teach DCI for number of RACH occasions however Yoo teaches DCI, and the PRACH configuration update including a number of random access (RACH) occasions in a frequency domain [¶0099, DCI indicates frequency resources for RACH which corresponds to “number of RACH occasions in a frequency domain” as per Applicant’s specification [0077]]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to specify DCI indicating frequency resources for the RACH configuration.
