    Abstract: A method of communication includes generating a traffic advertisement. The traffic advertisement indicates availability of data to be sent to multiple devices of a set of devices. The data includes first data to be sent to a first device and second data to be sent to a second device. The method also includes sending the traffic advertisement during a paging window. The method further includes receiving a first acknowledgement (ACK) during the paging window from the first device. The method also includes receiving a trigger message from the second device. The method further includes sending the first data to the first device during a data transmission window. The method also includes, in response to detecting receipt of the trigger message from the second device, sending the second data to the second device during the data transmission window without receiving a second ACK during the paging window from the second device.

    Abstract: Beacon-poll frames are transmitted from a station (STA) to a wireless AP in an opportunistic manner. In response to receiving a beacon-poll frame, the wireless AP transmits a unicast beacon frame to the STA, thereby eliminating the need for the STA to periodically wake up to receive broadcast beacon frames from the AP. The wireless AP may transmit the unicast beacon frame at a higher speed than a conventional broadcast beacon frame. As a result, the time that the STA must be awake to receive the unicast beacon frame is significantly less than the time that the STA must be awake to receive a conventional broadcast beacon frame, thereby resulting in significant power savings within the STA. The wireless AP may aggregate downlink (DL) data packets to be transmitted to the STA with the unicast beacon frame, resulting in further power savings within the STA.

    Abstract: Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes receiving one or more synchronization messages, each synchronization message having timing information and a cluster identifier, the timing information comprising anchor timing information, the cluster identifier being the same value as a cluster identifier of the apparatus. The method further includes determining whether a difference between a time value when a received synchronization message last received anchor timing information and a time value maintained for the apparatus is greater than a threshold. The method further includes discarding the received synchronization message if the difference exceeds the threshold.

    Abstract: Systems and methods of limiting wireless discovery range. A transmitting device may limit wireless discovery range by adjusting one or more transmission attributes of a discovery message, measuring inter-device distance based on range determination messages, or any combination thereof. A receiving device may limit wireless discovery range based on one or more attributes of a received discovery message, measuring inter-device distance based on range determination messages, or any combination thereof. Discovery messages may include a range adaptation bit indicating whether range adaptation is to be performed.

    Abstract: Methods, systems, and devices are described for wireless communication at a wireless communications device. The device may use several antennas to receive a signal, one of which may be shared between two radios. During signal reception, a radio may detect when the shared antenna is abruptly taken over by the other radio. The radio may detect the loss of the antenna by measuring an impedance mismatch. Alternatively, the radio may reference an antenna switch control that is used to facilitate the switch. After detection, the radio may recover from the antenna loss by adjusting signal processing. For example, the radio may modify a maximal ratio combining (MRC) operation. In certain examples, the device may disregard the signal version from the shared antenna in the computation of MRC weights. In some cases, the device may interrupt an MRC weight computation and use MRC weights from a previous calculation.
