Power saving via variable listen intervals in a WLAN

摘要

A wireless client device is associated with an access point in an association having a value for a listen interval parameter. The wireless client device determines, according to predefined considerations, a different value for the listen interval parameter, and declares the different value for the listen interval parameter in a wireless transmission to the access point. The listen interval parameter specifies a number of beacon intervals that can pass from a time the wireless client device listens for a beacon frame from the access point before the wireless client device listens for a next beacon frame from the access point.

1. A method of increasing a power saving potential of a wireless client device that is associated with an access point in an association having a value for a listen interval parameter, the method comprising:
determining, according to predefined considerations, a different value for said listen interval parameter, wherein said predefined considerations comprise a charge level of a battery to power said wireless client device; and declaring said different value for said listen interval parameter in a wireless transmission to said access point, wherein said listen interval parameter specifies a number of beacon intervals that can pass from a time said wireless client device listens for a beacon frame from said access point before said wireless client device listens for a next beacon frame from said access point.
