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: Aspects of the present disclosure relate to graphics domain transmission methods that utilize an adaptive compression pipeline to achieve low latency screen mirroring between a source device and a sink device. A source device captures a plurality of graphics domain frames, each of the graphics domain frames including one or more graphics command tokens. The source device utilizes an adaptive compression pipeline to compress the graphics domain frames based on one or more characteristics of the frames, and the adaptive compression pipeline is configured to perform at least one of scalable texture streaming, frame-based prediction, frame dropping, or data compression. The source device transmits the compressed frames to a sink device, and displays a rendered image of the graphics domain frames in time synchronization with a corresponding rendered image of the compressed frames displayed at the sink device.

Abstract: Various aspects of the present disclosure provide for detecting a condition indicating that a graphics processing unit (GPU) is in an unstable state while receiving GPU commands in a first wireless display mode, transmitting a GPU refresh request message and switching from the first wireless display mode to a second wireless display mode in response to detecting the condition, receiving data sufficient to reset the GPU from the unstable state to a stable state at a random access point (RAP) in a trace of the GPU commands, and switching from the second wireless display mode to the first wireless display mode after receiving the data. The GPU refresh request message may include information requesting the data sufficient to reset the GPU at an upcoming RAP in the trace of the GPU commands. Various other aspects are also provided throughout the present disclosure.

Abstract: Aspects of the present disclosure provide a method of wireless communication operable at a peer-to-peer (P2P) device, an apparatus, and a computer program product. A first P2P device determines a first interference margin report including a plurality of first interference margins. The first interference margins respectively correspond to a plurality of channels at a plurality of bandwidths. The first P2P device transmits the first interference margin report to a second P2P device. Prior to associating with the second P2P device to form a P2P group, the first P2P device selects at least one of a bandwidth, a channel, or a group owner of the P2P group based on the first interference margin report.

Abstract: Various aspects provide for determining an amount of time for a data packet at a medium access control (MAC) layer of the first apparatus to reach an application layer of a second apparatus, setting a MAC layer lifetime limit of the data packet based on the determined amount of time for the data packet at the MAC layer of the first apparatus to reach the application layer of the second apparatus, and discarding the data packet when the MAC layer lifetime limit of the data packet is reached. The MAC layer lifetime limit of the data packet comprises a duration of time during which the data packet is suitable for transmission. The MAC layer lifetime limit of the data packet may be different from a MAC layer lifetime limit of another data packet associated with an access category that is the same as the access category with which the data packet is associated. Various other aspects are provided.
