Abstract: Methods, systems, apparatuses, and devices are described for reverse channel audio (RCA) session establishment and management. A sink device may identify a unidirectional communication channel with a source device. The sink device may determine that a trigger is present, where the trigger is associated with a RCA transmission to the source device, and establish a RCA session for transmitting the RCA transmission to the source device based at least in part on the identified trigger. A source device may identify a unidirectional communication channel with a sink device and receive an indication that a sink device supports RCA transmissions, such as via the unidirectional communication channel. The source device may transmit a trigger to the sink device to initiate the RCA transmission, such as via the unidirectional communication channel, and receive the RCA transmission from the sink device based at least in part on the trigger.

Abstract: Methods, devices, systems, and non-transitory process-readable storage media for scalable data service distribution in WiFi Miracast. A processor of a source computing device in a WiFi Miracast network may group all sink computing devices scheduled to receive a frame or packet of a service into a single multicast group and transmit a multicast frame or packet to the sink computing devices. Individual sink computing devices in a WiFi Miracast network may be configured to send error logs indicating the quality of their respective wireless connections with a source computing device to the source computing device. A source computing device may add multicast group member sink computing devices to a unicast group based at least in part on missing and/or received error logs from the multicast group member sink computing devices.

Abstract: Methods, systems, and devices are described for using a back channel for communicating in a Wi-Fi peer-to-peer remote display connection. A Wi-Fi peer-to-peer remote display connection may be established with a source device. Communications may be transmitted from a sink device to the source device using a back channel of the Wi-Fi peer-to-peer remote display connection. The sink device may connect with a plurality of source devices. A plurality of input streams may be multiplexed into a single output stream. The single output stream may be distributed to the plurality of source devices using back channels of the Wi-Fi peer-to-peer remote display connection. In addition, a source device may connect, via a wired connection, with a sink device. Wi-Fi connection parameters may be exchanged with the wired connection. A Wi-Fi peer-to-peer connection may be established based at least in part on the Wi-Fi connection parameters.
