  • Ultra-wideband radio controller driver (URCD)-PAL interface
    Patent number: 8584132
    Abstract: Various embodiments provide a two-way interface between a URC driver (URCD) and various Protocol Adaption Layer (PAL) drivers. The two-way interface can enable bandwidth to be shared and managed among multiple different PALs. The two-way interface can also be used to implement common radio functionality such as beaconing, channel selection, and address conflict resolution. In at least some embodiments, the two-way interface can be utilized for power management to place PALs in lower power states to conserve power and to support remote wake-up functionality. Further, at least some embodiments can enable vendor-specific PALs to interact with vendor-specific hardware.

  • Power Settings in Wireless Ultra-Wide band Universal Serial Bus
    Publication number: 20100153760
    Abstract: Various embodiments enable a host controller, through its Protocol Adaption Layer (PAL) driver, to efficiently manage power consumption by employing “sleep mode” and “active mode” power settings. In some embodiments, the PAL driver may employ sleep mode settings to transition the host controller from an idle state to an energy conserving sleep state. In further embodiments, the PAL driver may use active mode settings to govern communications between the host controller and various devices, such as WUSB devices and others, thereby conserving power.
