Abstract: Power management operations are performed by devices communicating using multiple bands simultaneously where a first wireless band can be used to send and receive power management control frames for use on a second wireless band of a wireless network. In this way, a device that is in a sleep or dose power management state on a first band can be instructed to enter an awake power management state on the first band based on a communication received over a second band that is currently active and receiving data. Embodiments of the present invention enable power to be conserved when a band is not currently being used, or when there is no more data available (buffered) for a specific band.

Abstract: A UE performs a cell activation process in a wireless network. The UE calculates a first automatic gain control (AGC) setting based on downlink signals from a base station. The downlink signals include a coarse beam reference signal, a fine beam reference signal, and a conversion indication that indicates a power conversion between the coarse beam reference signal and the fine beam reference signal. The UE further calculates a second AGC setting based on the first AGC setting and the conversion indication. The UE performs a cell search using one of the first AGC setting and the second AGC setting, and performs fine time-frequency tracking using the other of the first AGC setting and the second AGC setting.
Abstract: Current steering digital-to-analog converters (DACs) are described. These DACs are suitable for high speed operation. Weight transistors conventionally used in DACs are replaced with resistors, resulting in a lower RC constant. Further, the resistors cause a smaller voltage drop, thus improving the voltage headroom of the DAC. Additionally, the current steering switches are biased in the triode region, as opposed to the saturation region as in conventional designs. Biasing the switches in the triode region results in a smaller drain-source voltage, which further improves the voltage headroom of the DAC. The triode operation further results in a substantially smaller output impedance, which leads to the output voltage being dictated primarily by the output transistor of the current path. Lastly, reset switches are added which reduce data-dependent memory effects that can otherwise produce distortion.
