Abstract: Systems and methods for channel-dependent CCA thresholds to balance different use cases in wireless networks are disclosed. In one aspect a device includes a receiver configured to receive transmissions on a plurality of channels.

Abstract: Systems, methods, and devices for simplified beamforming are provided. In one aspect, a plurality of signals from a signal transmitter are received over a wireless network on one or more receive antennas. One or more phase differences are then determined that maximize a signal to noise ratio of the plurality of received signals. Data representing the one or more phase differences is then transmitted to the signal transmitter.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for detecting ongoing transmissions and assessing channel state, based on midpacket detection. One example method generally includes receiving signals on a primary channel; detecting, based on the received signals, occurrence or non-occurrence of a first ongoing packet transmission on a primary channel; and generating at least one of a busy signal or an idle signal based on the detection. In this manner, collisions may be avoided.
