Office Action

§103
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 . 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. DETAILED ACTION This communication is in response to Application No. 18/683,215 filed on 12 February 2024. The response filed 17 April 2026 amends claims 1, 10, 44, and 89, cancels claims 4, 6, 9, 13-15, 18-21, 24-29, 32-41, 43, 45-88, 91, and 92, and presents arguments is hereby acknowledged. Claims 1-3, 5, 7, 8, 10-12, 16, 17, 22, 23, 30, 31, 42, 44, 89, and 90 are presented for examination. Response to Arguments Independent Claims 1, 44, and 89 On pages 8-10 of the response filed 17 April 2026, Applicant addresses the 35 U.S.C. 102 rejection made on the 21 January 2026 Non-Final Rejection. Applicant’s arguments, regarding the rejections under 35 U.S.C. 102, have been fully considered. On pages 8-10, Applicant argues that the You system fails to teach or suggest “wherein a 2-step RACH resource of a second type of terminal and a 4-step RACH resource of the second type of terminal are configured, and the method further comprises: instructing, by the network device, the first type of terminal to share at least part of PRACH resources of the second type of terminal via a first signaling.” Examiner respectfully agrees and finds this argument persuasive. You fails to disclose the amended limitations. Therefore, Examiner finds this argument persuasive. Dependent Claims 2, 3, 5, 7, 8, 10-12, 16, 17, 22, 23, 30, 31, 42, and 90 On pages 8-10 of the response filed 17 April 2026, Applicant addresses the 35 U.S.C. 102 rejection made on the 21 January 2026 Non-Final Rejection. Applicant submits that these claims are allowable at least as depending from an allowable independent claim, and further in view of the amendments to the independent claims, and the comments provided above. As per the comments above, Examiner found the arguments persuasive. With regards to allowability, Examiner has conducted a search and applied new art. Thus, a new rejection is established against the independent claims. Finality Due to the response filed 17 April 2026, Examiner is restarting prosecution. This action is a Non-Final 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. Claims 1-3, 5, 7, 8, 10-12, 16, 17, 22, 23, 30, 31, 44, 89, and 90 are rejected under 35 U.S.C. 103 as being unpatentable over US PGPUB 2021/0378021 A1 to You et al and in view of US PGPUB 2020/0288506 A1 to Lei et al. Regarding Claim 1, You discloses a resource allocation method, performed by a network device (FIG. 7, network device), the method comprising: configuring indication information for a first type of terminal (FIG. 7 and 0166-0168 provides for network device transmitting first indication information), wherein the indication information is configured to indicate a physical random access channel (PRACH) resource shared by the first type of terminal (0287 provides for where the first indication information may be a physical random access channel mask index PRACH mask index).

Same motivation as claim 1. Regarding Claim 89, similar rejection where the method of claim 1 teaches the network device of claim 89. Regarding Claim 90, similar rejection where the method of claim 44 teaches the terminal of claim 90. Claim 42 is rejected under 35 U.S.C. 103 as being unpatentable over the You/Lei system as applied to claim 1 above, and further in view of US PGPUB 2021/0307073 A1 to Huang et al. Regarding Claim 42, the You/Lei system discloses the method according to claim 1.

Huang, in a similar field of endeavor, discloses wherein a current cell only supports 4-step RACHs for the first type of terminal and a second type of terminal, and a 4-step RACH resource of the second type of terminal is configured (0298 provides for PRACH resources discloses 4-step RA without small data and 4-step CBRA), a 4-step RACH of the first type of terminal sharing the 4-step RACH resource of the second type of terminal (0298 provides for the RO(s) may be shared with other RA types when the NW configures the same PRACH resources for more than one RA type). One of ordinary skill in the art before the effectively filed date of the claimed invention would have recognized the ability to utilize the teachings of Huang for sharing resources between multiple 4-step RA types. The 4-step RA types of Huang, when implemented with the random access of the You/Lei system, will allow one of ordinary skill in the art to configure RACH resources in order to implement 4-step RACH for multiple types of resources. Therefore, the examiner concludes it would have been obvious to one of ordinary skill in the art before the effective filing date of the application to utilize the 4-step RA types of Huang with the random access of the You/Lei system for the desirable purpose of PRACH configuration.
