Abstract: An interface circuit in an electronic device may contend for access to a shared communication channel on behalf of the electronic device and a recipient electronic device, where the access has a duration. Then, the electronic device may provide a schedule frame intended for the recipient electronic device that includes information that specifies one or more time slots during the duration that are associated with the recipient electronic device and one or more communication functions of the recipient electronic device in the one or more time slots. Moreover, the electronic device may provide a data frame with data intended for the recipient electronic device. In response, the electronic device may receive a response frame associated with the recipient electronic device, where the response frame is received during at least one of the one or more time slots.

Abstract: An electronic device may include a transceiver, an antenna, and a front end module (FEM) coupled between the transceiver and antenna. Components on the FEM may operate on radio-frequency signals. The FEM may include a digital controller with a leakage management engine. The leakage management engine may monitor power supply voltages received by the FEM. In response to detection of a trigger condition, the leakage management engine may power off a set of the components while at least some of the FEM remains powered on. The trigger condition may be a change in the power supply voltages or a host command received from a host processor. Using the leakage management engine to power off the set of front end components may serve to minimize leakage current on the FEM, thereby maximizing battery life and shelf life for the device, without the use of bulky and expensive external load switches.
