Claim Rejections - 35 USC § 103
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 claimed 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.
Claims 13-30 are rejected 35 U.S.C. 103 as being unpatentable over Kessler et al. (USPGPUB No. 2017/0220502 A1, hereinafter referred to as Kessler) in view of Wild et al. (USPGPUB No. 2016/0211999 A1, hereinafter referred to as Wild) and further in view of Park et al. (USPGPUB No. 2022/0094413 A1, hereinafter referred to as Park).
Referring to claim 13, Kessler discloses a wired communication system {“via [wired communication] the bus 106… in a [system] vehicle”, see Fig. 13, [0157]}, comprising: a plurality of transceivers {“slave nodes 104 connected to … one or more communication transceivers”, see Figs. 13 and 18 [0183]} which are interconnected via a wired communication bus {“connected to the bus 106, a slave node 104 may also be associated with, as a peripheral device 108… Ethernet transceiver, Ethernet Audio Video Bridging (EAVB) transceivers, transceivers used for transmitting data in Internet of Things (IoT) applications, etc”, see Figs. 13 and 18 [0183], 1st two sentences};
and wherein a transmit signal strength {“nodes 104 on the bus 106 may support [transmit signal strength] beam-forming applications”, see Figs. 16 and 17 [0187], 1st sentence} of the respective transceivers is individually set {“[respective transceivers] reduced or no audibility outside of the area”, see Figs. 16 and 17 [0187]} such that, on the respective transceivers {“collect synchronous audio content to [respective transceivers] multiple slave nodes 104”, see Figs. 16 and 17 [0187]};
Kessler does not appear to explicitly disclose wherein a transmit signal strength of the respective transceivers is individually set such that, on the respective transceivers such that a ratio is reduced compared to other transmit signal strength configurations of the respective transceivers;
However, Wild discloses wherein a transmit signal strength {“[transmit signal strength] performance results for comparison of UFMC with OFDM”, see Fig. 2b [0057], 1st sentence} of the respective transceivers is individually set {individually set “under different timing offsets between different users”, see Fig. 2b, [0057], 1st sentence} such that {transceiver subcomponent “suppression (band pass) filters 106-1, 106-2, 106-p” (see Fig. 1, [0049]), also referred as “communication system 300 comprising the transmitter 100” (see Fig. 3, [0060], 1st sentence)}, on the respective transceivers such that a ratio {“required [ratio] E.sub.b/N.sub.0”, see Fig. 2b [0057], 3rd sentence; “same relative Carrier Frequency Oscillator (CFO) requirements will lead to much larger [maximum signal strength] absolute frequency shifts” (see Fig. 2b, [0057], last two sentences)} of transmit signals of other transceivers is reduced {“[maximum received signal strength CFO is normalized to the subcarrier spacing [including minimum received signal strength]” (see Fig. 2b, [0057], last two sentences)} compared to other transmit signal strength configurations of the respective transceivers {“OFDM, due to the possibility to reduce guard bands [of the respective transceivers filters 106-1, 106-2, 106-p], and to avoid using a CP which is discarded later on in the receiver”, see Fig. 2b [0057], last sentence}.
Kessler and Wild are analogous because they are from the same field of endeavor, time division multiplexing communication(s).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Kessler and Wild before him or her, to modify Kessler’s “multiple slave nodes 104” (see Figs. 16 and 17 [0187]) incorporating Wild’s “suppression (band pass) filters 106-1, 106-2, 106-p” (see Fig. 1, [0049]).
The suggestion/motivation for doing so would have been to provide pure frequency domain receiver processing, which may achieve a complexity almost as low as OFDM while offering additional performance gains compared to pure frequency domain processing, with modest increase in complexity (Wild [0033] paraphrased).
Therefore, it would have been obvious to combine Wild with Kessler to obtain the invention as specified in the instant claim(s).
Neither Kessler or Wild appears to explicitly disclose wherein that the ratio between a maximum received signal strength and a minimum received signal strength.
However, Park discloses a ratio {“by calculating [ratios] correlations”, see Fig. 7, [0063]} between a maximum received signal strength {“with respect to the [maximum received signal strength] received random access preamble messages”, see Figs. 5 and 7 [0063]} and a minimum received signal strength {“calculating correlations of the [minimum] basis preambles”, see Figs. 5 and 7, [0063]} of transmit signals {“may receive the random access preamble messages”, see Figs. 5 and 7 [0063], 1st sentence};
Kessler/Wild and Park are analogous because they are from the same field of endeavor, time division multiplexing communication(s).
Before the effective filing date of the claimed invention, it would have been obvious to one of ordinary skill in the art, having the teachings of Kessler/Wild and Park before him or her, to modify Kessler/Wild’s device incorporating Park’s “calculating correlations of the [minimum] basis preambles” (see Figs. 5 and 7, [0063]).
The suggestion/motivation for doing so would have been to incorporate/controlling a phase of the non-zero element of the linear combination matrix Φ for the transceivers/OFDM terminals (Park [0085], 1st sentence), the increase in the PAPR may be restricted (Park [0087], last sentence paraphrased).
Therefore, it would have been obvious to combine Park with Kessler/Wild to obtain the invention as specified in the instant claim(s).
