    摘要： 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.

    摘要： Reverse link data rate indications in wireless communication systems are defined with low identification overhead. Existence of a pilot signal is leveraged in order to reduce the overhead for identifying and selecting the reverse link data rate. At least two distinguishable pilot signals are defined, in which, based on the particular pilot signal present in the transmitted frame, at least one rate set from the multiple available rate sets can be determined. Reverse rate information in the transmitted frame is then used to identify which specific data rate within the determined rate set is used. Based on the identified data rate, the receiver may then decode the payload data in the transmitted frame.

    摘要： A User Equipment (UE) measures the signal quality of a dedicated downlink reference signal transmitted by a Base Station (BS) to the UE. If the signal quality is below a threshold, the UE initiates a measurement procedure to determine a target handover BS. The UE sequentially transmits an uplink reference signal on each of UE's beams. The BSs estimate the Angle of Arrival (AoA) of any received uplink reference signal, form a dedicated downlink beam pointed toward the AoA and transmit an acknowledgment to the UE on the corresponding beam. The UE estimates the signal quality of the received acknowledgements on the different UE beams, and transmits a handover message on the UE beam on which the acknowledgement with the highest signal quality is received. The uplink reference signal may comprise of a single preamble. The acknowledgement may comprise of a preamble, or a preamble followed by a small payload.
