Claims 1-7, 13-14, 17 and 21 are rejected under 35 U.S.C. 103 as being unpatentable by Jelonnek et al. US Patent Publication 20200212975 A1 (hereinafter Jelonnek) in view of Yan, US Patent Publication 20220021349 A1.
Regarding claim 1, Jelonnek discloses a method and
in a radio frequency (RF) transceiver system having a transmit chain with a beamforming array, a digital pre-distorter (DPD) comprising: a plurality of inputs including at least:
a first input (DPD 180) to receive a first signal corresponding to a signal desired to be transmitted via the transmit chain or a modified version of the signal desired to be transmitted via the transmit chain, and
a second input to receive a second signal corresponding to a signal associated with the beamforming array (connected to the beam-forming unit) or a translated version of the signal associated with the beamforming array;
DPD 108 receives the baseband transmit signal from DSP 102 "a digital predistortion unit (DPD) 108 controllable by a single predistortion model for feeding a pre-distorted signal to the parallel power amplifiers for linearizing the power amplifiers' outputs."[0013] The second input is the beamforming factor produced by beamforming unit BF 106.These are the control signals that tell the phase and magnitude shifters how to steer the antenna beam. "said predistortion unit is connected to the beam-forming unit and the power amplifiers' outputs."[0018] "At least one power amplifier model may be determined 306 on the basis of the power amplifiers' outputs and the beamforming factors."[0024]
And an output connected to provide a resulting pre-distorted signal (feeding a predistorted signal) to the transmit chain (parallel power amplifiers).
"The digital predistortion unit for the antennas may be controllable by a single predistortion model for feeding a predistorted signal to the parallel power amplifiers for linearizing the power amplifiers' outputs"[0018]

Jelonnek and Yan both address the identical problem of applying DPD in a beamforming multi antenna transmitter where predistortion musts account for both the transmit signal and a signal associated with the beamforming array. A person of ordinary skill in the art would have been motivated to incorporate the combining circuity of Yan into Jelonnek’s DPD framework. Jelonnek establishes that both signals must be combined for beam aware predistortion and Yan provides the known circuit technique to implement it. Yielding the predictable result of a DPD comprising circuitry that combines both signals to apply predistortion and no unexpected result arise from this combination.

Accordingly, it would have been obvious to a person of ordinary skill in the art before the effective filling date of the claimed invention to combine Pratt’s mathematical combining of beam weighting coefficients with the pre distorted transmission signal within a nonlinear model with Jelonnek’s beamforming factor aware DPD framework in which beamforming factors are used alongside the transmit signal to determine predistortion parameters and Yan’s combining circuitry that uses both transmit signal and beamforming array signal to produce predistortion. A person of ordinary skill in the art would have been motivated to combine these teachings for the benefit of producing a DPD in which the processed beamforming associated signal is explicitly combined with the transmit signal before being provided to the nonlinear combiner, such that the predistortion correction signals are computed as a direct algebraic function of both signals, yielding predicable results.
