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.
