Abstract: Systems, methods, and devices enable the implementation of antenna diversity techniques. Devices include a first wireless communications device that includes a plurality of antennas, and a transceiver coupled to the plurality of antennas and configured to send and receive data in accordance with a wireless transmission protocol, while the peer wireless communication device may have a single antenna or multiple antennas. Devices also include a processor configured to, in a first mode, calculate an angle of arrival (AoA) with the plurality of antennas or an angle of departure (AoD) associated with single antenna, and, in a second mode, send data to and receive data from a second wireless communications device via at least a first antenna of the plurality of antennas, where the first antenna is selected by the processor based on one of a first plurality of signal measurements between the first and second wireless communications devices.

Abstract: Systems, methods, and apparatus use a processor of a first device to wirelessly communicate with a second device using a first antenna. The processor selects the first antenna from a plurality of antennas based on comparing first antenna data associated with the first antenna with second antenna data associated with a second antenna.

Abstract: A method can include negotiating a target wake time (TWT) with a TWT session period (TWT SP) duration and generating mask data that inhibits communications according to a second standard during at least a portion of TWT SP. A method can further include, by operation of second communication circuits, generating a communications mask from mask data received from WLAN circuits, in response to the timing signal, synchronizing the communications mask with the TWT SP, and in response to the communications mask, inhibiting communications according to the second standard during at least a portion of the TWT SP. Corresponding devices and systems are also disclosed.

Abstract: An example system and method, during operation of first communication circuitry in a first operating mode comprising first power consumption, uses the first communication circuitry to perform packet arbitration for wireless communications by the first communication circuitry, second communication circuitry, and third communication circuitry. During operation of the first communication circuitry in a second operating mode comprising second power consumption, the example system and method uses the second communication circuitry to perform packet arbitration for wireless communications by the second communication circuitry and a third communication circuitry.
