Abstract: Parallel imaging magnetic resonance reconstruction is performed with temporal sensitivity. Rather than estimate the coil sensitivity once for each coil of an array, the coil sensitivity at different times is estimated. The movement of the patient may result in different sensitivities at different times. By using the time varying sensitivity in iterative, self-consistent, non-linear parallel imaging, real-time imaging may be provided with stable artifacts in view of increasing SNR even with higher reduction factors (e.g., 4-6).

Abstract translation: 平行成像磁共振重建以时间灵敏度进行。 不是对阵列的每个线圈估计线圈灵敏度，而是估计不同时间的线圈灵敏度。 患者的运动可能导致不同时间的不同灵敏度。 通过在迭代，自相一致的非线性并行成像中使用时变灵敏度，考虑到即使具有较高的减少因子（例如，4-6）也增加了SNR，可以提供稳定的伪像。

Abstract: Magnetic resonance reconstruction includes motion compensation. Inverse-consistent non-rigid registration is used to determine motion between shots. The motion is incorporated into reconstruction. The incorporation compensates for the motion resulting from the period over which the MR data is acquired.

The method comprises: a network side device confirming the value of an interference parameter of a target cell (201); on the basis of the value of the interference parameter of the target cell, the network side device confirming whether or not the target cell is capable of conducting autonomously the uplink-downlink configuration (202). Employment of the present invention allows for the normal operation of a dynamic uplink-downlink configuration, reduced interference between adjacent cells in a dynamic uplink-downlink configuration environment, and improved system efficiency.

Abstract: Disclosed are a method and a device for transmitting an aperiodic SRS in a TDD system. In the technical solution of the present invention, a symbol is defined for the transmission of the aperiodic SRS in a special subframe in the TDD system. This avoids a scenario in which the transmission position of the aperiodic SRS is undefined when a plurality of symbols that can be used to transmit the aperiodic SRS are available in an uplink pilot time slot (UpPTS). The problem of transmitting aperiodic SRS in a TDD system special subframe is thus solved. The modification to corresponding instruction messages is not extensive, and there is no overuse of system resources.
