Office Action

§112
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 . The examiner left voicemail on July, 06 and 07 2026 for examiner’s amendment. No response is received. Status of Claims Claims 11, 13-14, 29, 31-32 and 38 filed on May 18, 2026 are pending and claims 10, 12, 15-18, 28, 30, 33-37 are allowed. 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 11, 29 and 38 recite the limitation "the 4 CSI-RS" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claims 13-14 and 31-32 recite the limitation "the 1st and the 3rd CSI-RS resources" in line 2 and "the 2nd and the 4th CSI-RS resources" in line 3-4. There is insufficient antecedent basis for this limitation in the claim. Allowable Subject Matter Claims 11, 13-14, 29, 31-32 and 38 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims. Claims 10, 12, 15-18, 28, 30, 33-37 are allowed. A search has been performed and no prior art has been found that solely, or in any reasonable combination, reads on the claims as recited. The following is a statement of reasons for the indication of allowable subject matter: Regarding claims 10, 28 and 37, Noh (US 2021/0329517 A1) discloses a base unit for wireless communication, a method performed by a base unit and a remote unit for wireless communication comprising: at least one memory; and at least one processor coupled with the at least one memory and configured to cause the base unit to: transmit a configuration of an enhanced tracking reference signal (TRS) in [0020, 0108-0109], wherein the configuration of the enhanced TRS includes one or more Non-Zero Power (NZP) channel state information reference signal (CSI-RS) sets for frequency and timing tracking without a source Quasi Co-Location (QCL)-TypeC reference signal (RS) in [0127, 0135], and wherein each NZP CSI-RS set includes of 4 single port periodic NZP CSI-RS resources in one slot or 8 single port periodic NZP CSI-RS resources in two consecutive slots in [0120-0121]. You (US 2016/0366576 A1) discloses wherein each NZP CSI-RS set includes: for frequency range 2 (FR2), 4 single port periodic NZP CSI-RS resources in one slot in [0099-0103]. Either singularly or in combination, fail to anticipate or render the limitation "wherein each NZP CSI-RS set includes: for frequency range 2 (FR2), 4 single port periodic NZP CSI-RS resources in one slot or 8 single port periodic NZP CSI-RS resources in two consecutive slots with a same pattern in each slot, and for frequency range 1 (FR1), 8 single port periodic NZP CSI-RS resources in two consecutive slots with 4 single port periodic NZP CSI-RS resources in each slot". Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled "comments on Statement of Reasons for allowance".
