Abstract: Certain aspects of the present disclosure provide a method for performing interference suppression in spatial division multiple access (SDMA) systems. When the number of receive antennas of a receiver is equal or larger than the number of spatial streams intended for the receiver, the receiver may perform interference suppression on the signals received on all of its antennas. In addition, certain aspects of the present disclosure present a flexible SDMA technique in which a plurality of channel estimates that may be received from an explicit feedback or estimated implicitly, are combined. The combined channel estimate may be used in calculating the SDMA weights.

Abstract: Embodiments of the present disclosure provide techniques for reducing power consumption by wireless devices through transmission output power control. In an effort to avoid becoming a hidden node (meaning other devices in the network may not be able to detect the transmissions and may thus communicate in an interfering manner) for client devices and neighbouring access points, a client device may employ certain mechanisms prior to reduced power transmissions. A client device may transmit certain transmissions at full transmit power to "protect" subsequent data transmissions transmitted at reduced power. A client device may also evaluate the likelihood of becoming a hidden node and, while the likelihood is relatively low, the device may send all transmissions at reduced power.
