Aspects provide for selecting a precoder mode for a transmission, changing a cyclic prefix (CP) length based on the selected precoder mode, and transmitting a signal that includes the changed CP length.

Adaptive channel state information reference signal configurations for a 5G wireless communication network or other next generation network
In mixed numerology case, the performance of a physical downlink shared channel (PDSCH) can be improved by multiplexing PDSCH of one numerology with the channel state information reference signals (CSI-RS) of the other numerology and use of an advanced receiver.

Power meter disconnect switch operation
Techniques are disclosed herein for improved power meter disconnect switch operation, which may include opening and/or closing of the disconnect switch. In particular, for reasons such as reduction of electromechanical stress on the disconnect switch, the disconnect switch may be operated based, at least in part, on a voltage at the load side of the disconnect switch. For example, in some cases, the disconnect switch may be opened slightly before a zero crossover of a waveform corresponding to the load side voltage. As another example, in some cases, the disconnect switch may be closed slightly before or slightly after a zero crossover of a waveform corresponding to the load side voltage. |

Control circuit of switching power supply device
In a control circuit of a switching power supply device, a switching cycle generating unit controls a switching cycle in keeping with a signal of an error voltage detected on a secondary side to stabilize an output voltage at a target value. A load current for overload protection is estimated based on a value produced by integrating a resonant current at an integrator and averaging at an averaging calculation unit. Here, although the switching cycle is correlated to the ratio of input/output voltages, the switching cycle is negatively correlated to the input voltage because the output voltage is controlled so as to be constant. A correction calculating unit uses a signal that decides the switching cycle as information corresponding to the input voltage, which eliminates the need to detect the input voltage. |

In a semiconductor device, an IGBT and an SJMOSFET connected in parallel have respective gate terminals controlled independently of each other. When a high voltage occurs and a high current flows caused by short-circuit in an external circuit under a condition of ON state of the IGBT and SJMOSFET, an operational amplifier in the control IC detects the overcurrent through the IGBT and controls the gate signal to restrict the current through the IGBT. After that, the operational amplifier throttles the current through the IGBT according to a reference voltage of a capacitor decreasing by the discharge through a constant current source, thus conducting soft-OFF operation of the IGBT. |
