Abstract
Transmit power control functionality in wireless audio systems may be implemented by way of a Transmit Power Control (TPC) algorithm devised to control power for both source and sinks in a multi sink session, to reduce power consumption. Information may be passed back and forth between the source and sink devices to adjust power based on the shared information. The TPC algorithm may allow power control on both ends of an RF link, and may have multiple sink devices communicating with a source device. Furthermore, the multiple sink devices and the source device may each be operating at different power levels, and adjust their respective power levels as instructed by the TPC algorithm. Power control is therefore implemented on both ends of the link, where multiple sources and sinks may all operate at different power levels, and all individually adjust their respective power levels.
