    Abstract: Various techniques and schemes pertaining to extremely-high throughput (EHT) multi-link maximum channel switching in wireless communications are described. A station (STA) multi-link device (MLD) receives an indication from a reporting access point (AP) affiliated with an AP MLD on one link of multiple links. The STA MLD determines a channel switching time when a reported AP switches from operating in a current channel of the reported AP to operating in a new channel on one other link of the multiple links based on the indication.

  • Publication number: 20240013692
    Abstract: To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.
