A method, comprising: transmitting from a radio frequency transmitter of a first wireless communication station (310, 410, 510, 610) of an magnetic resonance imaging system a first transmit signal (1119, 4119, 6119) comprising a first baseband signal upconverted with a first carrier signal, the first carrier signal having a first carrier frequency which is a product of a first value and a first local oscillator frequency of a first LO of the first wireless communication station, the first carrier signal being synchronous with the first LO of the first wireless communication station; receiving via a wireless channel at an RF receiver of a second wireless communication station (320, 420, 520, 620) of the MRI system a phase shifted first transmit signal (1229, 4229, 6229) comprising the first transmit signal with its phase shifted by a first channel phase shift which is equal to a time delay of the wireless channel multiplied by the first carrier frequency; at the second wireless communication station, multiplying a second baseband signal with a correction signal obtained from the phase shifted first transmit signal to produce a corrected second baseband signal, and transmitting a second transmit signal (4219, 6219) comprising the corrected second baseband signal upconverted with a second carrier signal, the second carrier signal having a second carrier frequency which is a product of a second value and a second LO frequency of a second LO of the second wireless communication station, wherein the second transmit signal has a second transmit carrier frequency which is a product of the second value and the first LO frequency and which is synchronous in frequency with the first LO of the first wireless communication station; receiving via the wireless channel at an RF receiver of the first wireless communication station a phase shifted second transmit signal comprising the second transmit signal with its phase shifted by a second channel phase shift which is equal to the time delay of the wireless channel multiplied by the second transmit carrier frequency; and ascertaining at the first wireless communication station the time delay of the wireless channel from the received phase shifted second transmit signal. transmitting from a radio frequency transmitter of a first wireless communication station (310, 410, 510, 610) of an magnetic resonance imaging system a first transmit signal (1119, 4119, 6119) comprising a first baseband signal upconverted with a first carrier signal, the first carrier signal having a first carrier frequency which is a product of a first value and a first local oscillator frequency of a first LO of the first wireless communication station, the first carrier signal being synchronous with the first LO of the first wireless communication station; receiving via a wireless channel at an RF receiver of a second wireless communication station (320, 420, 520, 620) of the MRI system a phase shifted first transmit signal (1229, 4229, 6229) comprising the first transmit signal with its phase shifted by a first channel phase shift which is equal to a time delay of the wireless channel multiplied by the first carrier frequency; at the second wireless communication station, multiplying a second baseband signal with a correction signal obtained from the phase shifted first transmit signal to produce a corrected second baseband signal, and transmitting a second transmit signal (4219, 6219) comprising the corrected second baseband signal upconverted with a second carrier signal, the second carrier signal having a second carrier frequency which is a product of a second value and a second LO frequency of a second LO of the second wireless communication station, wherein the second transmit signal has a second transmit carrier frequency which is a product of the second value and the first LO frequency and which is synchronous in frequency with the first LO of the first wireless communication station; receiving via the wireless channel at an RF receiver of the first wireless communication station a phase shifted second transmit signal comprising the second transmit signal with its phase shifted by a second channel phase shift which is equal to the time delay of the wireless channel multiplied by the second transmit carrier frequency; and ascertaining at the first wireless communication station the time delay of the wireless channel from the received phase shifted second transmit signal.
