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: A method and apparatus are disclosed for searching for a radar signal within signals received by a wireless device. The wireless device may receive signals within a first frequency segment and a second frequency segment, which is adjacent to the first frequency segment. The wireless device may determine Fast Fourier Transform (FFT) bins associated with the first frequency segment and the second frequency segment. The wireless device may combine the FFT bins associated with the first frequency segment and the second frequency segment and may search for the radar signal within the combined FFT bins.

Abstract: A method and apparatus are disclosed for searching for a radar signal within signals received by a wireless device. The wireless device may receive signals within a first frequency segment and a second frequency segment. The first frequency segment and the second frequency segment may be non-contiguous. The wireless device may determine energy within the first frequency segment and the second frequency segment and may detect a strong signal event with the first and/or the second frequency segments. In response to detecting the strong signal event, the wireless may search for the radar signal based, at least in part, on the determined energy within the first frequency segment and the second frequency segment and the strong signal event.
