Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an AP, that reduce the overhead associated with triggering an uplink transmission from the STA. In some examples, the STA may also calculate its transmit power by decoding a spatial reuse subfield of the trigger frame from the AP and identifying downlink pathloss measurements of the trigger frame. Accordingly, the STA may identify acceptable interference level of the AP and calculate a transmit power in order to minimize interference at the AP. In some aspects, the STA may transmit its uplink packets to a different AP on one or more punctured channels at the calculated transmit power of the STA.

Abstract: Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.

Abstract: Methods, systems, and devices for wireless communications are described for coordination between multiple access points (APs) for communications within a transmission opportunity (TxOP). A first AP may gain channel access for a TxOP, and may coordinate with at least a second AP to allow both the first AP and the second AP to transmit and receive wireless communications during the TxOP. The first AP, upon gaining channel access following a successful contention-based channel access procedure, may initiate a scheduling phase with the second AP to schedule of resources within the TxOP for the first and second APs. The first AP may initiate a multi-AP coordinated transmission phase following the scheduling phase, during which both the first AP and second AP may communicate with one or more associated STAs.

Abstract: This disclosure provides systems, methods and apparatuses for indicating a data rate of a packet. The transmitting device may select the data rate of a data field of the packet to be transmitted to the receiving device, and may select a pattern to embed within a preamble of the packet based on the selected data rate. In some implementations, the transmitting device may select a first structure including a first number of instances of a sequence or its logical complement if the selected data rate is a low data rate, and may select a second structure including a second number of instances of the sequence or its logical complement if the selected data rate is a high data rate.

Abstract: A first computing device includes a memory, and at least one processor. The at least one processor may be configured to establish a wireless connection to a second computing device using a Wi-Fi Direct Application Services Platform (ASP), transmit data from a car connectivity consortium (CCC) Information Element (IE) to the second computing device, and establish a MirrorLink session using Universal Plug and Play (UPnP) to the second computing device via the wireless connection. The at least one processor may be further configured to establish a Wireless Serial Bus (WSB) session to the second computing device using the Wi-Fi Direct ASP via the wireless connection, and transmit data via the WSB session to the second computing device.

Abstract: In an embodiment, an Internet of Things (IoT) controller receives information from IoT devices over an IoT communications interface. The IoT controller establishes a wireless media presentation session with a user device with the IoT controller acting as a source and the user device acting as a sink. The IoT controller generates a displayable IoT control interface for the IoT devices and sends the displayable IoT control interface to a user device within a media stream of the wireless media presentation session. The user device displays the displayable IoT control interface and sends the IoT controller user input feedback over a user input feedback channel. The IoT controller determines whether to modify one or more settings associated with the at least one IoT device based upon the user input feedback.

Abstract: Methods, apparatuses, and computer readable media for resource allocation signaling in a high efficiency wireless local area network (WLAN) are disclosed. A transmitter may generate an indication that a first channel of a plurality of channels associated with a transmission frame has been punctured, the transmission frame including a WLAN signaling field. The transmitter may identify information associated with the WLAN signaling field corresponding to the punctured first channel. The transmitter may transmit the information associated with the WLAN signaling field in a second channel of the plurality of channels. The transmitter may transmit the indication that the first channel has been punctured in the second channel or in a second WLAN signaling field of the transmission frame.
