Abstract: For one disclosed embodiment, data corresponding to an idle duration for one or more downstream devices may be received. Power may be managed based at least in part on the received data. Other embodiments are also disclosed.

Abstract: For one disclosed embodiment, a transition from a first state to a second, different state for at least a portion of a downstream device may be identified. The first and second states may correspond to different levels relating to activity for at least a portion of the downstream device. Data corresponding to a service latency may be transmitted to an upstream device in response to the identified transition for one or more upstream devices to manage power based at least in part on the service latency. Other embodiments are also disclosed.

Abstract: A mobile station in a wireless network includes a roaming timer. The roaming timer is set based on various criteria, and when the roaming timer expires, an attempt to roam is performed.

Abstract: A method and apparatus for intelligent power management for low power link states. Some embodiments include methods, apparatuses, and systems for a device coupled to a controller via a link; a link power management engine to alter a power state of the link based on a transaction and some knowledge of future transactions between the device and the controller; and a memory or logic to store the link power management engine. In some embodiments, the memory stores information about at least one of the following: the power state of the link, the device buffering, the controller or device state or a history of transactions. In some embodiments, the device is a peripheral of a computer system. In some embodiments, the method may include transitioning the device to various link states. Other embodiments are described.

Abstract: In some embodiments, a method to manage power in a wireless communication device, comprises in a wireless networking adaptor, changing an operational status of a wireless networking adaptor to a sleep mode and transmitting a sleep message from the wireless networking adaptor to a host driver in an electronic device coupled to the networking adaptor, in the electronic device, determining whether a sleep duration specified in the sleep message exceeds a threshold, in response to a determination that the sleep duration specified in the sleep message exceeds a threshold implementing a selective suspend operation on the electronic device, and monitoring for a wake event, and in response to a determination that the sleep duration specified in the sleep message does not exceed a threshold, flushing one or more bulk IN buffers, and monitoring for a wake event.

Abstract: A method, apparatus, and system for coordinated link power management. Some embodiments of a method include receiving an exit latency for each of a group of link states for a link, with a device being coupled to an interconnect via the first link. A latency tolerance value is determined and communicated, and a platform latency is received. The method further provides for determining a link budget for the device, the link budget indicating an amount of time available for an exit from a link state for the device; and selecting one of the link states based at least in part on the link budget.

Abstract: In some embodiments, an electronic apparatus comprises at least one processor, a plurality of components, and a policy engine comprising logic to receive latency data from one or more components in the electronic device, compute a minimum latency tolerance value from the latency data, and determine a power management policy from the minimum latency tolerance value.
