Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.

Abstract: In some examples, a method includes receiving, at a first device, availability information from a second device during a connection set-up phase of communication of a neighbor aware network (NAN) or during a NAN discovery window. The connection set-up phase includes an exchange of device capability information. The method also includes, based on the availability information indicating that the second device is available during a transmission window of a data link group of the NAN to receive data from the first device, sending data from the first device to the second device during the transmission window without performing a message exchange to determine an availability of the second device.

Abstract: A method includes transmitting, at an electronic device in a neighbor aware network (NAN), a discovery beacon at a designated discovery beacon transmission time. The designated discovery beacon transmission time is determined based on an internal clock of the electronic device. The method further includes synchronizing the internal clock to a clock reference that is external to the electronic device.

Abstract: When a first node cannot hear a second node, the second node is “hidden” to the first node. In response to receiving a trigger frame, the two nodes may inadvertently transmit response frames at approximately the same time. The response frames may collide with each other, thereby causing delays in node discovery in a NAN. Provided herein are methods, apparatuses, and computer program products for reducing collisions in wireless communication. In some configurations, nodes may receive trigger frames that indicate a reduction in the rate that response frames are transmitted when traffic load conditions are high. In some configurations, nodes located in different coverage areas (e.g., a “hidden area” and a “non-hidden area”) may transmit response frames at different times. In some configurations, the nodes may refrain from transmitting their response frames upon hearing that another node having a higher serving preference rank is transmitting.

Abstract: Methods, systems, and devices are described for supporting simultaneous (e.g., overlapping) data communications by a wireless communication device. More specifically, the described features generally relate to supporting SBS communications by providing mechanisms to help mitigate interference and/or coordinate medium access. One mechanism involves aligning the data communications to mitigate interference. Another mechanism involves using channel reservation signal (e.g., a clear-to-send-to-self (CTS2S) signal) to help maintain simultaneous medium access. Yet another mechanism involves setting a second backoff period for a second channel based at least in part on a first backoff period for a first channel in wireless devices.

Abstract: Methods, systems, and apparatuses are described for adaptive dwell time for scan procedures. A wireless station (STA) may identify a scan period during which a passive scan procedure is performed on a first channel. The STA may analyze a channel congestion metric during at least a portion of the scan period. The STA may transition from the passive scan procedure to an active scan procedure on the first channel during the scan period based at least in part on the analyzed channel congestion metric.

Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system through efficient transmissions and acknowledgements of information between an AP and a station. The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency.

Abstract: A method for sending one or more service discovery messages includes detecting, at a proxy device of a network, a client device having access to the network. The method also includes sending a service discovery message from the proxy device to one or more other devices in the network. The service discovery message is associated with a service and is sent on behalf of the client device. The client device is a publisher of the service of a subscriber of the service.
