    Abstract: In a synchronous application to control forward link (FL) data rates in a satellite system, user equipment (UE) repeatedly transmits a quality control measurement (QCM) index during a QCM period. During this QCM period, the data rate cannot change. The associated satellite transmits at a new rate corresponding to the QCM index. The UE knows that it will begin receiving new data at the new rate after a QCM delay. In an asynchronous application, a satellite transmits a rate change signal over a FL rate indication channel (RICH). A UE monitors the FL RICH for this signal. When the signal quality is to be low, the satellite sends only a single bit of the QCM index over a first orthogonal channel. When the signal quality is not low, the satellite transmits each bit of the QCM index in a separate orthogonal channel of the FL RICH.

    Abstract: Techniques are provided which may be implemented in various methods, apparatuses, and/or articles of manufacture for use by a device that is operable in a plurality of modes, including “higher power mode” and a “lower power mode”. A timing circuit may be set based, at least in part, on a phase value obtained from a signal from a ground-based transmitter, and operation of the device may be selectively transitioned to a lower power mode wherein the device uses the timing circuit. In certain example implementations, operation of the device to the lower power mode may be selectively transition and based, at least in part, on a determination that one or more attribute values satisfy a profile test indicating that the electronic device is likely to be within a characterized environment, and/or a determination that the electronic device is likely to be in a constrained motion state.
