Abstract: A method performed by an access point (AP) that includes: receiving, by the AP from a second station, an information request frame for requesting whether or not a wakeup schedule is established between the AP and a first station; and transmitting, by the AP to the second station, an information response frame including a first wakeup schedule element in response to the information request frame. If the AP has an established wakeup schedule with the first station, the first wakeup schedule element includes information about the establish wakeup schedule, and if the AP has no established wakeup schedule with the first station, a length of the first wakeup schedule element is set to zero by the AP. The method also includes transmitting, by the AP to the second station, an unsolicited information response frame when the AP updates the first station's wakeup schedule.

Abstract: A method for transmitting load information in a wireless local area network. The method according to one embodiment includes generating, by an access point (AP), basic service set (BSS) load information, the BSS load information including a multiple input multiple output (MIMO) channel underutilization field; and transmitting, by the AP, the BSS load information. The MIMO channel underutilization field indicates a spatial stream underutilization that is defined as a percentage of time that the AP has one or more underutilized spatial domain resources for a given busy time of a wireless medium. The spatial stream underutilization is calculated based on a maximum number of spatial streams supported by the AP and a number of one or more utilized spatial streams transmitted by the AP.
