Office Action

§102 §112
DETAILED ACTION Claims 1-20 have been examined. 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 . Claim Objections Claims 11 and 16 are objected to because of the following informalities: Claim 11, line 7, “the uplink BWPS” should be changed to “the plurality of uplink BWPs”. Claim 16, line 9, “, ,” should be changed to “,”. Lines 9-10, “the initial uplink BWP” should be changed to “the deactivated initial uplink BWP”. Appropriate correction is required. 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, 3-6, 9-13, 14-15, and 18 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. Claim 1 recites the limitation "the source cell" in line 10. There is insufficient antecedent basis for this limitation in the claim. Claim 3 recites the limitation "the source cell" and “the PCell” in lines 2 and 4. There is insufficient antecedent basis for this limitation in the claim. Claim 4 recites the limitation "the transmitting the at least one signal" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 5 recites the limitation "the deactivated initial uplink BWP" in lines 2 and 4. There is insufficient antecedent basis for this limitation in the claim. Claim 6 recites the limitation "the starting PRB" and “the deactivated initial uplink BWP” in line 5. There is insufficient antecedent basis for this limitation in the claim. Claim 9 recites the limitation "the source cell" in line 1. There is insufficient antecedent basis for this limitation in the claim. Claim 10 recites the limitation "the source cell" and “the PCell” in lines 1-2. There is insufficient antecedent basis for this limitation in the claim. Claim 11 recites the limitation "the PCell" in line 10 and 12. There is insufficient antecedent basis for this limitation in the claim. Claim 12 recites the limitation "the configuration parameters" and “the candidate cell” in line 1. There is insufficient antecedent basis for this limitation in the claim. Claim 13 is similarly rejected as claim 12 as it depends from claim 12 and includes all the limitations of claim 12 Claim 14 recites the limitation "the candidate cell" in line 2. There is insufficient antecedent basis for this limitation in the claim. Claim 15 recites the limitation "the source cell" in line 1. There is insufficient antecedent basis for this limitation in the claim. Claim 18 recites the limitation "the starting PRB" in line 5. There is insufficient antecedent basis for this limitation in the claim. 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) 1-4, 7-9, 11, 14-17, and 19-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by US 20230199571 A1 to Babaei (hereinafter “Babaei”). As per claim 1, Babaei discloses a method comprising: receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters of a candidate cell for a layer 1 or layer 2 triggered mobility (LTM) procedure (Babaei [0104] FIG. 12B shows an example of a contention-free random access (CFRA) process. Msg 1 (random access preamble) and Msg 2 (random access response) in FIG. 12B for CFRA may be analogous to Msg 1 and Msg 2 in FIG. 12A for CBRA. In an example, the CFRA procedure may be initiated in response to a PDCCH order from a base station. The PDCCH order for initiating the CFRA procedure by the wireless device may be based on a DCI having a first format (e.g., format 1_0). The DCI for the PDCCH order may comprise a random access preamble index, an UL/SUL indicator indicating an uplink carrier of a cell (e.g., normal uplink carrier or supplementary uplink carrier) for transmission of the random access preamble, a SS/PBCH index indicating the SS/PBCH that may be used to determine a RACH occasion for PRACH transmission, a PRACH mask index indicating the RACH occasion associated with the SS/PBCH indicated by the SS/PBCH index for PRACH transmission, etc. In an example, the CFRA process may be started in response to a beam failure recovery process. The wireless device may start the CFRA for the beam failure recovery without a command (e.g., PDCCH order) from the base station and by using the wireless device dedicated resources. [0139] Example embodiments may enable mechanism and procedures of L1/L2 based inter-cell mobility, for example for mobility latency reduction. In example embodiments, multiple candidate cells may be configured/pre-configured and the configurations of the multiple candidate cells may be maintained to allow fast application of configurations for candidate cells in response to L1/L2 signaling.
