    Abstract: Techniques are disclosed relating to oscillator settling time allowance. In one embodiment, an apparatus may include an oscillator and oscillation detection and control circuitry. The oscillation detection and control circuitry may be configured to awaken an oscillator at a predetermined time and detect an edge transition of oscillations. The oscillation detection and control circuitry may further be configured to measure the time from the power-on indication to edge transition detection. In one embodiment, the oscillation detection and control circuitry may be configured to store the measured time and use the measured time instead of the predetermined time for subsequent oscillator awakenings. In some embodiments, the apparatus may further include circuitry configured to compensate for an expected oscillator settling behavior.

    Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system. In embodiments, power conservation may be achieved by adaptively controlling power modes of a wireless communication device, using a modulation and coding scheme (MCS) value as a factor for guidance. According to one aspect, the device may be in a reception mode. While in a first power mode, the device may receive control information for incoming data that is being transmitted via a transmission frame. The control information may be located in a first portion of the frame with the data following in a second portion of the frame. The control information may include or otherwise indicate an MCS value corresponding to the MCS applied to the incoming data. Based on the MCS value, the device may be adaptively switched to a second power mode for receiving the incoming data.

    Abstract: Methods and apparatuses are described in which dynamic voltage and frequency scaling may be used to save power when processing packets in a wireless communications device. In some cases, inframe detection may allow the device to determine whether to transition from a first (e.g., lower) voltage level to a second (e.g., higher) voltage level to process one or more packets of a received frame. For some packet types the first voltage level may be maintained. In other cases, the device may determine a bandwidth to use from among multiple bandwidths supported by the device. The bandwidth may be determined based on channel conditions. A voltage level may be identified that corresponds to the determined bandwidth and a processing voltage may be scaled to the identified voltage level. The device may be configured to operate in wireless local area network (WLAN) and/or in a cellular network (e.g., LTE).
