    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: A wireless communications device that produces phase-synchronized local oscillator (LO) signals. The device includes a first transceiver chain to receive a first timing signal and a second transceiver chain to receive the first timing signal and a second timing signal. The first transceiver chain includes a first frequency divider to convert the first timing signal to a first LO signal.

A second frequency divider in the second transceiver chain converts the selected timing signal to a second LO signal, and a phase alignment circuit aligns a phase of the second LO signal with a first alignment signal. The first alignment signal is activated, for a limited duration, in response to a change in state of the mode select signal.

    Abstract: This disclosure describes techniques for providing active interference cancellation in a wireless communication system having a Bluetooth transmit chain and a WLAN receive chain. A signal sampled from the Bluetooth transmit chain is gain and phase adjusted to offset interference in the WLAN receive chain. A quadrature phase shifter may be used to generate quadrature components of the sampled signal that are selectively combined to achieve a desired phase adjustment. The phase shifter may be stabilized by a variable capacitor. These techniques may be extended to MIMO systems.
