Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may use wireless local area network (WLAN) signaling fields in a multiple user transmission preamble to communicate with a number of stations greater than a threshold. For example, the AP may determine that the number of stations is greater than the threshold and generate a compression indicator and an indication of the number of stations to include in a first signaling field. The AP may then generate a spatial configuration indicator in a second signaling field based on the number of stations and transmit the first and second signaling fields in a preamble of the multiple user transmission. Upon receiving the preamble, a station may identify the compression indicator and number of stations, and the spatial configuration indicator in the first and second signaling fields, and decode the multiple user transmission using a determined spatial decoding scheme.

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: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

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: Various aspects provide for receiving identity information from a station (STA) that identifies the STA as a sensor-type STA, determining whether communication attributes of the STA correlates with communication attributes expected for a sensor-type STA, and determining that the identity information received from the STA is false when the one or more communication attributes of the STA is uncorrelated with the one or more communication attributes expected for a sensor-type STA. Additional aspects provide for initiating one or more remedial actions upon determining that the identity information is false. The communication attributes may pertain to packet size, inter-arrival time, and/or inter-arrival time variance. The remedial actions may include blocking a future communication with the STA, communicating a warning message to the STA, and/or assigning the STA to a particular access window. Communications by the STA may comply with aspects of Institute of Electrical and Electronics Engineers (IEEE) 802.11ah.

Abstract: A method and apparatus for group owner (GO) renegotiation are provided. For example, the method and apparatus may be used for GO renegotiation in a wireless personal network (WPAN), for example, a 60-gigahertz (60 GHz) peer-to-peer (P2P) wireless network. The incumbent group owner (e.g., personal base station set (PBSS) control point (PCP)) controls the operation of the group. GO renegotiation can occur, for example, when a newly arriving device (e.g., a prospective group owner) is trying to connect to the PBSS and/or, for example, with PCP rearrangement among members of an existing group. As an example, after the formation of the group, the PCP may want to relinquish the role of being the PCP. A procedure is described for deciding among clients and the PCP which device will assume the role of group owner from the existing PCP in the event the role of group owner is to be reassigned.

Abstract: In an embodiment, a first media presentation session is established between a first Source and the Sink, and a second media presentation session between a second Source and the Sink. First and second media streams are streamed to the Sink by the first and second Sources, respectively. The Sink presents the first and second media streams in respective portions of a display screen, and detects user input at the Sink that is indicative of a trigger to transfer data originated from the first Source to the second Source. The Sink coordinates with one or both of the first Source and the second Source to facilitate the data to be delivered to the second Source in response to the detection. As a result of the coordination, the second Source receives the first Source-originated data (e.g., from the first Source directly, or via the Sink).

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.
