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 describes a power save mechanism for devices in a neighbor awareness networking (NAN) network. In some aspects, a NAN device is able to enter into a power save mode during a window agreed to between the NAN device and a NAN peer device. A NAN device transmits, to a NAN peer device, an indication that the wireless communication device is to enter a power save mode. For example, the NAN device may transmit a MAC packet with a more data (MD) bit set to 0. The NAN peer device may indicate that the NAN device is allowed to enter the power save mode by transmitting a MAC packet with the MD bit set to 0, or the NAN peer device may indicate that the wireless communication device is not to enter the power save mode by transmitting a MAC packet with the MD bit set to 1.
