  • VOLTAGE TRANSIENT SUPPRESSION IN A SWITCHED MODE POWER SUPPLY
    Publication number: 20220302838
    Abstract: A switched mode power supply, SMPS, which supplies an output voltage to a load, wherein a load current drawn by the load varies over time in accordance with load scheduling information. The SMPS comprises a voltage conversion circuit which converts an input voltage of the SMPS to the output voltage, and a controller which generates a control signal (SSW) based on a feedback signal indicative of the output voltage, and controls the voltage conversion circuit using the control signal to regulate the output voltage. The controller further generates a modified control signal (S?SW) using an indication of a change in the load current that is based on the load scheduling information, and controls the voltage conversion circuit using the modified control signal before the change in the load current occurs to suppress a voltage transient in the output voltage caused by the load current change.

  • Controlling Energy Consumption of a Wireless Network Node
    Publication number: 20220272641
    Abstract: A user equipment receives a signal indicating a time schedule for intermittent transmission of information from a base station managing a cell. The intermittent transmission of information enables the UE to perform mobility measurements when the cell is in a discontinuous transmission (DTX) mode and the UE is an active terminal not served by the cell. The UE performs, based on the intermittent transmission of information, a mobility measurement when the cell is in the DTX mode and reports the mobility measurement to the base station.
