  • Patent number: 10477523
    Abstract: Disclosed are a response information transmission method, system and device. A base station can configure at least two PUCCH transmission carriers for user equipment, accordingly, the user equipment can select at least one PUCCH transmission carrier from the at least two PUCCH transmission carriers which are configured by the base station to transmit response information fed back on a corresponding subframe, and accordingly, the base station can receive the response information which is fed back by the user equipment on at least one PUCCH transmission carrier. The technical solution increases the number of PUCCH transmission carriers, so that compared with the manner of only configuring one PUCCH transmission carrier in the prior art, the reconfiguration operations caused by the movement of user equipment can be reduced, thereby reducing the condition that UE cannot normally communicate in the process of reconfiguration, and reducing the signaling overhead caused by the reconfiguration operation.

  • Patent number: 10258246
    Abstract: MRI techniques seek to simultaneously measure physiological parameters in multiple directions, requiring the application of multiple encoding magnetic field gradient waveforms. The use of multiple encoding waveforms degrades the temporal resolution of the measurement, or may distort the results depending on the methodology used to derive physiological parameters from the measured data. The disclosed Direct Inversion Reconstruction Method (DiR) provides distortion-free velocity images with high temporal resolution, without changing the method of acquiring the phase data. The disclosed method provides a more stable and accurate recovery of phase-based dynamic magnetic resonance signals with higher temporal resolution than current state-of-the-art methods.
