Office Action

§112
DETAILED ACTION Applicant’s response filed 4/8/26 has been considered. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claims 1-20 are pending. Prior rejections under 35 USC 112 are maintained in view of amendments and remarks made herein. Application is 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. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-20 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. For example, claim 1 recites: PNG media_image1.png 731 807 media_image1.png Greyscale The claim states: PNG media_image2.png 139 812 media_image2.png Greyscale Does each CBG have at least one data unit packet with a corresponding CBG recoding index? Perhaps the claim limitation should recite something like, “…sending, by a first medium access control layer of a transmitting end, at least one code block group, each CBG including at least one data packet with a corresponding CBG recording index information…” Next the claim recites: PNG media_image3.png 230 831 media_image3.png Greyscale It is not clear how the feedback (ACK or NACK) can received for a CBG at the same time that it is transmitted? The claim states at least one CBG. So in the case of one CBG is transmitted, then is the time slot period for transmission long enough to include time for the second MAC layer to send feedback information? Or is the feedback sent by the second MAC layer for a previous CBG? In this case it would mean that there are more than one CBG, right? Then the claim states: PNG media_image4.png 179 809 media_image4.png Greyscale Does the reporting by the first MAC layer happen for a previous CBG? In that case there would have to be more than one CBGs that are transmitted. This limitation appears to be contradictory. First it says to report the index based on the feedback received and then it states to do so without waiting for the feedback indicating NACK. Are there multiple feedbacks being referred in this limitation? Again, this would mean that there has to be more than one CBG transmitted. Independent claims 8 and 15 are rejected for similar reasons. Respective dependent claims 2-7, 9-14 and 16-20 are rejected at least based on dependency. Corrections are requested. It is the Examiner’s conclusion that the claims of the present application, as presented, are not clear. Applicants are encouraged to formulate claim language that clearly defines the novelty of the application. Pertinent prior arts are cited for Applicants’ review. Prior rejections are maintained under 35 USC 112. If Applicants believe an interview with the Examiner might be useful, they are welcome to contact the Examiner with proposed amendments for a discussion.
