Abstract: Systems and methods for wireless communications are disclosed. More particularly, aspects generally relate to an apparatus for wireless communications. The apparatus generally includes an interface for communicating with a plurality of wireless nodes via a plurality of antennas, and a processing system configured to determine a power state of each of the plurality of wireless nodes, and change from a first antenna mode used for communicating with the wireless nodes using a first number of spatial streams to a second antenna mode used for communicating with the wireless nodes using a second number of spatial streams, based on the determined power states of the wireless nodes.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a time period to delay entering a power save mode (leak guard) for wireless communications. In one aspect, a wireless communication device may adjust a time period to delay entering a power save mode. The time period is associated with the wireless communication device remaining awake to prevent an access point from transmitting to the wireless communication device while the wireless communication device is in the power save mode. The wireless communication device also may provide, to the AP, an indication that the wireless communication device is entering a power save mode, and the wireless communication device may enter the power save mode. Entering the power save mode is at least the adjusted time period after providing the indication to the AP.
