Office Action

§102
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 . Information Disclosure Statement The information disclosure statement (IDS) submitted on 2/4/26 is being considered by the examiner. Response to Arguments Applicant's arguments with respect to claim 23, filed 3/3/26, have been fully considered but they are not persuasive. On pages 9-11 of the applicant’s response, the applicant argues that Liou fails to disclose “a first subset of TCI field codepoints each associated with a respective downlink TCI state; a second subset of TCI field codepoints each associated with a respective uplink TCI state”. Regarding the arguments above, the examiner respectfully disagrees with the applicant. As pointed out in the office action and applicant’s remarks. Liou discloses in paragraph [0056] that: In some embodiments, a UE may monitor and/or receive one or more beam indication(s). A beam indication may carry or indicate a TCI field. A beam indication may be a (scheduling) DCl. In one embodiment, the UE may monitor and/or receive one or more joint TCI. The UE may monitor and/or receive one or more UL TCI. The UE may monitor and/or receive one or more DL TCI. Paragraphs [0074] and [0075] then state that: [0074] In one embodiment, the first MAC CE may be used/applied for indicating that a multiple of joint TCI states among the one or more joint TCI state(s) map to one or a multiple of TCI codepoints in a TCI field of a DCI. [0075] In one embodiment, the first MAC CE may be used/applied for indicating that a multiple of joint TCI states among the one or more joint TCI state(s) can be used/applied for receiving DL transmission and/or transmitting UL transmission (if further indicated). For clarity, the examiner will try to use diagrams to illustrate the mapping of the Liou reference to the claim limitation. A single codepoint is a subset of the total codepoints. Liou teaches multiple TCI codepoints which is equivalent to the first, second, third subset of codepoints. Liou Multiple TCI codepoints [0074] TCI codepoint 1—TCI codepoint 2--- TCI codepoint 3 Instant Application First, Second, Third Subset of TCI codepoints First (subset) TCI codepoint 1--- Second (subset) TCI codepoint 2 – Third (subset) TCI codepoint 3 Liou teaches multiple TCI states and each codepoint from above is associated with (maps to) one of the states below [0074]. Liou Multiple joint TCI states (use of and/or in [0075] UL Only Allowed (State 1) – DL Only Allowed (State 2) – (UL AND DL Allowed) Instant Application Respective downlink TCI state – respective uplink TCI state – respective downlink TCI state AND respective uplink TCI state Therefore, as the claim language reads, Liou does teach the argued limitations. Claim Rejections - 35 USC § 102 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. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 23-40 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Liou et al (Pub No: 2022/0217695). As to claim 23, Liou teaches a method performed by a wireless device for handling downlink and uplink Transmission Configuration Indicator, TCI, states (Liou, [0006], a method for a UE configuring and using configured TCI states), the method comprising: receiving a Downlink Control Information, DCI, comprising an indication that indicates a selected TCI field codepoint (Liou, [0056][0074], a UE receives DCI with indication of a TCI field) among: a first subset of TCI field codepoints each associated with a respective downlink TCI state (Liou, [0074][0085], TCI field codepoints in the DCI that map to DL only TCI state); a second subset of TCI field codepoints each associated with a respective uplink TCI state (Liou, [0074][0076], TCI field codepoints in the DCI that map to UL only TCI state); and a third subset of TCI field codepoints each associated with a respective downlink TCI state and a respective uplink TCI state (Liou, [0075], TCI field codepoints in the DCI that map to joint UL/DL TCI state); and performing one or more actions based on the selected TCI field codepoint (Liou, [0072-0075], using/applying the activated TCI codepoints for the TCI state for receiving on DL and transmitting on UL) , and wherein the wireless device is configured by a Medium Access Control, MAC, Control Element, CE, and the MAC CE (Liou, [0072], the UE is configured by a MAC CE) is configured to: associate each of the first subset of TCI field codepoints with the respective downlink TCI state (Liou, [0074][0085], TCI field codepoints in the DCI that map to DL only TCI state); associate each of the second subset of TCI field codepoints with the respective uplink TCI state (Liou, [0074][0076], TCI field codepoints in the DCI that map to UL only TCI state); and associate each of the third subset of TCI field codepoints with the respective downlink TCI state and the respective uplink TCI state (Liou, [0075], TCI field codepoints in the DCI that map to joint UL/DL TCI state), and wherein for each TCI state activated via the MAC CE (Liou, [0073], the MAC CE activates TCI state), an associated field is included to indicate whether the activated TCI state applies to uplink only, downlink only, or both downlink and uplink (Liou, [0140-0143], the MAC CE has a field to indicate the activated TCI state [0074]) .

Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action.
