Office Action

§112
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 . DETAILED ACTION This office action is in reply communication filed on 06/14/2023. Claims 1-20 are pending. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claims 1-6, 8-15, and 17-20 are rejected under 35 U.S.C. 112(b) paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, the applicant regards as the invention. Regarding claims 1, 10, 19, the claims recite the limitation “wherein a parameter K is a size of inverse fast Fourier transform (IFFT) of cyclic- prefix orthogonal frequency-division multiple access (CP-OFDMA)”. It is unclear the limitation “a parameter K is a size of IFFT of CP-OFDMA” has anything to do with the wake-up signal and its configuration when modulated using one-off keying (OOK) and generated by a multi-carrier amplitude shift-keying waveform. The functional steps for generate/transmit/receive the WUS using OOK and MC-ASK waveform generation do not indicate a relationship with parameter K tied to CP-OFDMA IFFT size. Therefore, the claims are unclear and indefinite. For the purpose of examination, examiner will interpret the claims as best understood. All dependent claims 2-6, 8-9, 11-15, 17-18, and 20 are also rejected based on their rejected independent claims 1, 10, and 19 respectively. Conclusion Any inquiry concerning this communication or earlier communications from the examiner should be directed to PHONG LA whose telephone number is (571)272-2588. The examiner can normally be reached on Monday through Friday from 7:30 A.M. to 4:00 P.M. (EST).
