Office Action

§102
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 . Title Objection The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. 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. Claim(s) 1, 68-86 is/are rejected under 35 U.S.C. 102 as being anticipated by Dinan WO 2025010408. 1. A method, comprising: performing, at least one measurement of one or more candidate cell of, a cellular network, wherein the at least one measurement comprises a layer 1 (L1) or a layer 2 (L2) measurement (Dinan: [0384-0386] fig. 36 - the layer 1/2 measurement report may be triggered by receiving a triggering indication (e.g., a DCI or a MAC CE) indicating to report the layer 1/2 measurement of one or more candidate target PCell (e.g., Cell 1, Cell 2, etc.)); reporting the at least one measurement of the one or more candidate cell to the cellular network (Dinan: [0385] fig. 36 - In response to receiving the triggering indication, the wireless device may (after performing the L1/2 measurement) transmit the layer 1/2 measurement report indicating whether at least one candidate target PCell has better CSI measurement than the current PCell); decoding, from the cellular network, a first indication of a plurality of activated transmission configuration indication (TCI) states for at least one candidate cell (Dinan: [0406] fig. 37 - the wireless device may receive at T1, a TCI state activation/deactivation MAC CE (e.g., TCI MAC CE) indicating activation/deactivation of one or more TCI states of Cell 1); and after decoding the first indication, decoding, from the cellular network, a cell switch command (CSC) signal comprising a second indication of a selected TCI state from plurality of activated TCI states, to use after a cell switch (Dinan: [0407-409] fig. 37 - the wireless device may receive, at T2, an LTM CSC MAC CE (e.g., CSC MAC CE, an LTM MAC CE, etc.) triggering the LTM procedure comprising switching a PCell from Cell 0 to Cell 1. The CSC MAC CE may comprise a first field indicating Cell 1, a second field indicating a valid TA value, a third field indicating a TCI state from the multiple activated TCI states (e.g., based on the TCI MAC CE received at T1), or activating (and indicating) a TCI state from a plurality of configured TCI states (which are configured in the one or more RRC messages)): and after the cell switch: applying the selected TCI state to a first candidate cell indicated by the CSC signal (Dinan: fig. 36-37 – the wireless device may select a PUSCH occasion, from the plurality of PUSCH occasions of the CG, corresponding to a SSB associated with the indicated TCI state (by the CSC MAC CE). In the example of FIG. 37, the indicated TCI state is TCI state 1 which is associated with SSB1. Since SSB1 is associated with PUSCH occasion 1, the wireless device selects PUSCH occasion 1 for the first uplink data transmission via Cell 1); and releasing at least one other activated TCI state of the plurality of activated TCI states (Dinan: [0307, 0324, 0623] - the wireless device may release RRC configuration parameters of the source PCell and the MCG associated with the source PCell). 68. The method of claim 1, wherein the CSC signal comprises a Medium Access Control (MAC) Control Element (CE) (Dinan: [0407-409] e.g., CSC MAC CE, an LTM MAC CE, etc.). 69. The method of claim 1, wherein said releasing the at least one other activated TCI state comprises releasing the TCI states of the plurality of activated TCI states except the selected TCI state (Dinan: [0307, 0324, 0623] e.g., the wireless device may release RRC configuration parameters of the source PCell and the MCG associated with the source PCell, apply the RRC configuration parameters of the PCell 1). 70. The method of claim 1, The method of further comprising decoding, from the cellular network, a third indication that indicates for which candidate cell the plurality of activated TCI states are to be released (Dinan: fig. 37, 40-42 [0149, 0307, 0324, 0406, 0623] e.g., For example, a MAC CE may use a bitmap (e.g., one bit per SCell) to indicate which SCells (e.g., in a subset of configured SCells) for the UE are . 71. The method of claim 1, wherein the at least one measurement of the one or more candidate cell comprises a reference signal received power (RSRP) measurement (Dinan: [0180] measure a reference signal received power (RSRP)). 72. The method of claim 1, wherein said releasing the at least one other activated TCI state comprises a candidate cell dependent TCI state release (Dinan: [0308] e.g., release RRC configuration parameters of the source PCell and an MCG/SCG associated with the source PCell). 73. The method of claim 1, wherein the first indication comprises a Medium Access Control (MAC) Control Element (CE) (Dinan: [0407-409] e.g., CSC MAC CE, an LTM MAC CE). Regarding claims 74-86, the independent claim and each dependent claim are related to the same limitation set for hereinabove in claims 1, 68-73, where the difference used is a “method & apparatus” with a processor and a memory (Dinan: Referring to FIG. 15, the wireless device 1502 includes a processor 1518, a memory 1524 [0263]) and the wordings of the claims were interchanged within the claim itself or some of the claims were presented as a combination of two or more previously presented limitations. This change does not affect the limitation of the above treated claims. Adding these phrases to the claims arid interchanging the wording did not introduce new limitations to these claims. Therefore, these claims were rejected for similar reasons as stated above. 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.
