CTFR 18/327,782 CTFR 86131 Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 6-8 and 20-22 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. Regarding claims 6 and 20, none of the prior art of record alone or in combination with other disclose or render obvious the claimed limitations including “calculate a ratio based on two or more of the parameters, wherein the one or more criteria specify selection of a scheme based on a comparison of the ratio to the at least one threshold value” when considered as a whole along with other claimed limitations. Claims 7-8 and 21-22 have been objected by virtue of dependency on claims 6 and 20 respectively. Claim Rejections - 35 USC § 103 07-06 AIA 15-10-15 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 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. 07-20-aia AIA The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the 20claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. 07-21-aia AIA Claim s 1, 11-12, and 29 are rejected under 35 U.S.C. 103 as being unpatentable over Hosseini et al. (US 2019/0253229, hereinafter Hosseini) in view of Sengupta et al. (US 2020/0382354, hereinafter Sengupta) . Regarding claims 1 and 29, Hosseini discloses an apparatus for wireless communication (fig. 1), comprising: a memory (para 0104; memory) comprising computer-executable instructions (para 0104; memory store computer-executable software/instructions); and one or more processors configured to execute the computer-executable instructions (para 0103; a processor to execute computer – readable instructions) and cause the apparatus to: select, based on one or more criteria, a scheme from a plurality of schemes for generating a waveform (para 0038; 0110 and 0112; Channel estimates, derived by the channel processor from a reference signal transmitted by the base station or from feedback by the base station, may be used to select the appropriate coding, modulation, waveform generation schemes) that accounts for unavailable frequency resources within an allocation of resource elements (REs) (para 0023; 0044; 0049; available communication resources (including time, frequency and/or spatial dimension) within resource are considered for allocation which implies while generating time-domain signal/waveform unavailable resources are being considered for skipping); obtain a sequence of frequency domain symbols (para 0038; A resource element may consist of one symbol period and one subcarrier (e.g., a 15 KHz frequency range). A resource block may contain 12 consecutive subcarriers in the frequency domain and, for a normal cyclic prefix in each OFDM symbol, 7 consecutive OFDM symbols in the time domain (1 slot), or 84 resource elements); and output the waveform for transmission (para 0112; The symbols produced by the transmit processor may be provided to a transmit frame processor to create a frame structure. The generated frames are provided to a transmitter, which provides various signal conditioning functions including amplification, filtering, and modulating the frames onto a carrier for uplink transmission over the wireless medium through the antennas). Hosseini does not expclitly disclose wherein the selected scheme avoids the unavailable frequency resources when mapping frequency domain symbols to REs; generating the waveform by mapping at least some of the sequence of frequency domain symbols to available REs within the allocation according to the selected scheme.

It would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify Hosseini’s method/system by having Sengupta’s disclosure in order to provide improvements in resource efficiency of a communication system. Regarding claim 11, Hosseini discloses wherein the one or more criteria are based on at least one of: a modulation and coding scheme (MCS) associated with the waveform (para 0110 and 0112; Channel estimates, derived by the channel processor from a reference signal transmitted by the base station or from feedback by the base station, may be used to select the appropriate coding, modulation, waveform generation schemes); a type of the waveform; a capability of a receiving device; or at least one parameter related to performance of the apparatus. Regarding claim 12, Hosseini discloses wherein the one or more processors are further configured to execute the computer-executable instructions and cause the apparatus to: obtain an indication of a scheme for generating a waveform that accounts for unavailable frequency resources (para 0023; 0044; 0049; available communication resources (including time, frequency and/or spatial dimension) within resource are considered for allocation which implies while generating time-domain signal/waveform unavailable resources are being considered for skipping), wherein the selection of the scheme is based on the indication (para 0112; Channel estimates, derived by the channel processor from a reference signal transmitted by the base station or from feedback by the base station, may be used to select the appropriate coding, modulation, waveform generation schemes) . 07-21-aia AIA Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Hosseini/Sengupta in view of Mao (WO 2018/060397, hereinafter Mao) .
