  • Publication number: 20250093442
    Abstract: A magnetic resonance imaging system, and a radio-frequency signal processing method and radio-frequency coil therefor are provided. The method comprises: receiving, via a radio-frequency coil, a radio-frequency pulse transmitted from a transceiver coil to generate a radio-frequency field that excites a subject to be examined; and sending, via the radio-frequency coil, a magnetic resonance signal received from the subject to be examined to the transceiver coil, wherein the radio-frequency coil and the transceiver coil are electromagnetically coupled.

  • Publication number: 20240389033
    Abstract: Embodiments of the present disclosure provide method and apparatus for EIRP-constrained communication. A method performed by a network device includes determining a first power back-off value for a transmission of a signal based on an effective isotropic radiated power (EIRP) limit. The method further includes determining a second power back-off value for a transmission of a channel based on the EIRP limit. The method further includes transmitting the signal to a terminal device based on the first power back-off value. The method further includes receiving a channel state information report from the terminal device. The method further includes estimating a channel quality of the transmission of the channel based on the channel state information report, the first power back-off value and the second power back-off value.
