As to claim 1 Noh teaches A wireless communication terminal comprising:
a generation unit configured to generate a data unit including, in a preamble, position information indicating a position of a mid-amble ([0080] [0085]Fig. 9, Fig. 11, a transmitting STA generates an EHT PPDU frame and transmits it to a receiving STA(s).frame includes, preamble, data field, midamble, Each midamble is present after M data symbols, where M is a positive integer (e.g., 4, 8, 10, or 16)/location of midamble)
a wireless control unit configured to cause ([0034] [00167] Fig. 2, Fig. 3A, processor executing a computer program (e.g., a sequence of instructions) contained in a memory or other non-transitory machine-readable storage medium)
sending of the data unit generated by the generation unit to the wireless communication device. ([0080] a transmitting STA generates an EHT PPDU frame and transmits it to a receiving STA(s). The receiving STA receives, detects, and processes the EHT PPDU)Noh does not teach parameter information of a non-orthogonal multiple access scheme that is used by the wireless communication terminal in a multi-domain of the non-orthogonal multiple access scheme to be applied to sending to a wireless communication device;
Kang teaches parameter information of a non-orthogonal multiple access scheme that is used by the wireless communication terminal in a multi-domain of the non-orthogonal multiple access scheme to be applied to sending to a wireless communication device;([page 3] lines 4-15, non-orthogonal multiple access extended space-frequency equivalent channel matrix of the time-frequency resources/scheme, for first targets the spatial domain and then the frequency domain/multi-domain, different non-orthogonal multiple access (NMO) pattern vectors e.g., parameters, are preferentially allocated to the uplink data of each terminal on the same time-frequency resource; , uplink data transmission is performed using pattern vectors of different non-orthogonal multiple access).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Kang with the teaching of Noh because Kang teaches that full use of NOMA multi-domain would allow more terminals to transmit data simultaneously on the same time-frequency resources, thereby improving the system capacity or the number of access terminals.(Kang [page 8])
Claim 12 is/are interpreted and rejected for the same reasons as set forth in claim 1.
Claim(s) 2, 3, 6 - 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Noh, Kang and further in view of Minotani et al. (US 20220240269 A1)hereinafter Minotani
As to claim 2 the combination of Noh and Kang specifically Noh teaches further comprising:

in the preamble ([0047][0074] Fig. 3b, FIG. 6 receiving STA receives, detects, and processes the PPDU frame, the frame format 600 includes a PHY preamble 602)
Noh does not teach the first data unit also including type information indicating the non-orthogonal multiple access scheme, wherein the wireless control unit determines whether or not to perform sending to which the non-orthogonal multiple access scheme is applied, on a basis of the preamble of the received first data unit, and
in a case where it is decided to perform sending to which the non-orthogonal multiple access scheme is applied, the generation unit generates a second data unit, and
the wireless control unit causes sending of the generated second data unit to the wireless communication device.
Kang teaches the first data unit also including type information indicating the non-orthogonal multiple access scheme, ([page 7] lines 17-21, different non-orthogonal multiple access (NMO) pattern vectors are preferentially allocated to the uplink data of each terminal on the same time-frequency resource, and the uplink data of one terminal corresponds to one or more NMO pattern vectors)
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Kang with the teaching of Noh because Kang teaches that full use of NOMA multi-domain would allow more terminals to transmit data simultaneously on the same time-frequency resources, thereby improving the system capacity or the number of access terminals.(Kang [page 8])
the combination of Noh and Kang does not teach wherein the wireless control unit determines whether or not to perform sending to which the non-orthogonal multiple access scheme is applied, on a basis of the preamble of the received first data unit, and
in a case where it is decided to perform sending to which the non-orthogonal multiple access scheme is applied, the generation unit generates a second data unit, and
the wireless control unit causes sending of the generated second data unit to the wireless communication device.
Minotani teaches wherein the wireless control unit determines whether or not to perform sending to which the non-orthogonal multiple access scheme is applied, on a basis of the preamble of the received first data unit, ([0052] [0088] Fig. 2, Fig. 9, NOMA determiner 204 determines whether STA 200 is a user subjected to non-orthogonal multiplexing by NOMA e.g., multiplexing scheme based, NOMA determiner 204 outputs the NOMA determination result to data decoder 205.)
and
in a case where it is decided to perform sending to which the non-orthogonal multiple access scheme is applied, the generation unit generates a second data unit, and ([0074][0077] Fig. 1, Fig. 2, Scheduler 105 performs NOMA scheduling for STA 200, for example, based on the radio quality information of each STA 200 inputted from data decoder 104; Data generator 106 generates a data sequence (i.e., DL data)e.g., data sequence includes second data, for STA 200, and outputs the generated data sequence to encoder 107)

([0077][0080][0081] Fig. 2, Fig. 9, Data generator 106 generates a data sequence (i.e., DL data)e.g., data sequence includes second data, for STA 200, Radio transmitter 110 time-multiplexes the data section inputted from modulator 108 and the preamble section inputted from preamble generator 109.
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Minotani with the teaching of Noh and Kang because Minotani teaches identifying by STA number of spatial streams common to NOMA users would reduce the overhead of the NOMA control information, thereby improving the system performance..
