Regarding claims 1 and 10, Coe teaches a passive intermodulation (PIM) source positioning method, wherein the method comprises:
Sequentially (periodically-[0014]) performing, by a network device (base station 17/32—Fig. 2/3) using a transmit antenna (antenna 13-Fig. 2/3 ) configured to transmit downlink signals to a terminal (wireless device 14)( [0036], base station 32/17 includes at least one radio 21/12{antenna 13—[0037]} for transmitting and receiving communication uplink and downlink signals; [0037], Downlink signals are transmitted via an antenna 13 for transmission to wireless devices 14 .) and using a receive antenna (antenna 13-Fig. 2/3) configured to receive uplink signals from the terminal (wireless device 14) ([0036]; [0037], Signals {i.e. uplink} from wireless devices 14 are received by the antenna 13.), a scanning process on each of a plurality of scanning spots (at least one PIM source 18—[0033]—i.e. plural) ([0038], PIM detection system 24 of base station 17/32 of Fig. 2/3 scanned over {using antenna 13—see [0039]} to detect downlink signals and PIM signals {to determine presence and location of a PIM source 18—[0036]}) by at least:
sending via the transmit antenna (antenna 13), for a first scanning spot (PIM source 18-Fig. 2), a plurality of downlink signals on which the precoding processing has been performed and with different frequencies(bands) ([0036], base station 32/17 includes at least one radio 21/12{antenna 13—[0037]} for transmitting and receiving communication uplink and downlink signals. Radio downlink signals in different radio bands interact with a PIM source 18{see also [0033]}.), and receiving, via the receive antenna (antenna 13), an uplink PIM signal for the first scanning spot (PIM source 18-Fig. 2) ( [0039], antenna 13 is also used as a wideband antenna to receive PIM signals {the PIM source 18, which generates PIM signals –see [0033]}.) (Hence in brief, the BS using antenna 13, performs a scanning process on each of PIM source 18 by: sending via the antenna 13, DL signals with different bands for a PIM source 18 and receiving via the antenna 13, an UL PIM signal for the PIM source 18.),

However, in an analogous art, Nishimoto teaches a passive intermodulation (PIM) source positioning method, wherein the method comprises:
a plurality of downlink signals on which the precoding processing has been performed ([0059], Fig. 6, precoder unit 12 of the base station 1 calculates a precoding matrix corresponding to the desired terminal. Wherein signals transmitted from the transmission antennas are multiplied with the first matrix, which is the preceding matrix); and

Wherein signals transmitted from the transmission antennas are multiplied with the first matrix, which is the preceding matrix.) (Hence obvious, the BS performs precoding processing on DL signals based on precoding matrix.), wherein the precoding matrix is a complex conjugate matrix ([0059], precoding matrix is B.sub.i=V.sub.i.sup.(n)V.sub.i.sup.(e); Obvious a complex conjugate.) of at least one eigenvector obtained through singular value decomposition (SVD) of a first electric([0061]) field matrix of a first scanning spot (at BS) ([0059], Fig. 6, signals transmitted from the transmission antennas are multiplied with the first matrix, which is the preceding matrix. Wherein precoder unit 12 of the base station 1 calculates a precoding matrix corresponding to the desired terminal based on the expression (7), B.sub.i=V.sub.i.sup.(n)V.sub.i.sup.(e); wherein [0058], the 12 calculates an eigenvector matrix V(bold).sub.i.sup.(e), which is a second matrix, from a desired component H(bold).sub.iV(bold).sub.i.sup.(n) that is singular value decomposition.), wherein the first electric([0061]) field matrix(1st matrix of the BS) is obtained based on an antenna electromagnetic field model and a downlink configuration parameter ([0029], downlink communication in communication system, in which MU-MIMO scheme is adopted, is modeled{wherein the base station carries out processing called precoding—[0003]}; also [0044], the BS having a configuration.)

Hence 1st scanning/test spot/point is one of the pluralities.), and the uplink PIM signal is generated by excitation by any at least two of the plurality of downlink signals ([0041], two sinusoidal signals with preset frequencies are combined into an excitation signal.) ([0042], test signal generator applies a preset excitation signal to the passive device under test and transmit the passive intermodulation (PIM) interference signal to the spectrum analyzer for display, so that the PIM interference signal can be detected by the probe according to the frequency.) (Hence it is obvious the uplink PIM signal is generated by excitation by two downlink signals.); and

When the PIM interference signal reaches its maximum value, the position of the corresponding probe is the PIM interference source of the passive device under test.),(Hence it is obvious, the probe determines a PIM source {when the PIM signal from a point reaches its maximum value} from the plurality of scanning/test spot/point of the passive device. ) wherein the determining is based on uplink PIM signals respectively corresponding to the plurality of scanning spots (each point of passive device under test) ([0042], In test system--The near-field scanning magnetic field detection probe is moved close to the passive device under test to detect passive intermodulation(PIM) interference signal at each point of the passive device under test and transmit the PIM interference signal(S) to the spectrum analyzer for display, so that the PIM interference signal can be detected. When the PIM interference signal reaches its maximum value, the position of the corresponding probe is the PIM interference source of the passive device under test.)
