  • Publication number: 20240073773
    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: 20100052985
    Abstract: The prevent invention provides an activating and positioning method for an electronic device comprising at least a Global Navigation Satellite System (GNSS) receiver and a storage unit. The storage unit is utilized for storing a time file recording time information so that the time file can be obtained when activating the electronic device, and the time information recorded by the time file can be set as a current system time of the electronic device. Then, the activating and positioning method of the prevent invention activates the GNSS receiver to perform a positioning process according to the system time. Thus, the prevent invention can overcome disadvantages of the prior art which records system time by using hardware scheme.
