A method and apparatus to reduce the idle link power in a platform. In one embodiment of the invention, the host and its coupled endpoint(s) in the platform each has a low power idle link state that allows disabling of the high speed link circuitry in both the host and its coupled endpoint(s). This allows the platform to reduce its idle power as both the host and its coupled endpoint(s) are able to turn off their high speed link circuitry in one embodiment of the invention.

Method and apparatus to reduce idle link power in a platform

Techniques for powering up a wireless power receiving device are described herein. An example computing device includes a power receiving unit to wirelessly receive power from a power transmitting unit. The platform hardware includes a System on a Chip (SoC), a multicomm device, and a power sequence manager. The multicomm device is for wireless communication with two or more communication standards. One of the communication standards is used as a side channel for communicating with the power transmitting unit. The power sequence manager component manages activation of platform components of the platform hardware during a low battery cold boot condition. Upon detecting wireless power, the multicomm device is configured to automatically activate and the power sequence manager component is to suppress activation of other platform components of the platform hardware.

Powering up a wireless power receiving device

An embodiment of the present invention provides a method, comprising dynamically reserving free channel time blocks for directional transmissions in a wireless personal area network (WPAN) by a transceiver communicating with a Coordinator and the Coordinator allocating a part or a whole of unreserved channel time blocks for a directional link during a handshake with the transceiver.

Techniques enabling dynamic bandwidth reservation in a wireless personal area network

A system on a chip (SoC) is provided including processing cores and a root complex. The transaction requests are communicated between a root port of the root complex and a device, the root port including electrical idle (EI) exit detect circuitry and a reference clock source. The root port supports a first link state, in which the reference clock source and EI exit detect circuitry of the root port are disabled but a common mode voltage is maintained, and a second link state, in which the reference clock source and EI exit detect circuitry are disabled and the common mode voltage is not maintained. The root port transitions to the first link state based on a service latency requirement of the device being less than a threshold and to the second link state based on the service latency requirement being greater than or equal to the threshold.

Apparatus to reduce idle link power in a platform

Briefly, a mechanism to avoid interference and improve channel efficiency in mmWave Wireless Personal Area Networks (WPANs) is disclosed. In particular, interference information during various time periods is tracked and used to optimize transmission scheduling. Further, a mechanism is provided to improve communication latency by distributing responsibility for coordination of slots amongst multiple transmitting devices.

Mechanism to avoid interference and improve communication latency in mmWave WPANs

An embodiment of the present invention provides an apparatus, comprising a transceiver operable in a wireless personal area network, wherein the transceiver is configured to communicate with a coordinator and at least one receiver and wherein the transceiver and the coordinator use a directional reservation of free channel time blocks using contention-based slots, by selecting uniformly at random contention slots by the transceiver and transmitting a bandwidth reservation request message specifying the requested reservation period using directional transmission pointed towards the coordinator.

Apparatus and method adapted for directional bandwidth reservation with fixed announcement slot in wireless networks

Embodiments of the present invention provide a method and apparatus for a multiple-entity wireless communication adapter, including at least a first connection module to communicate first signal traffic corresponding to a basic service set station entity, a second connection module to communicate second signal traffic corresponding to an entity that is not a basic service set station, and a shared physical layer able to process both the first and the second signal traffic. Additional features are described and claimed.

Method and apparatus of multiple entity wireless communication adapter

A method and apparatus for adaptive network allocation are described herein. In some embodiments, a node may receive a request-to-send (RTS) packet that includes duration information and a basic service set identifier (BSSID). The network node may update a network allocation vector based at least in part on a received signal strength of the RTS packet and the BSSID. Other embodiments may be described and claimed.

Method and apparatus for adaptive network allocation

Embodiments of methods and apparatus for aggregating a plurality of media access control-layer frames into a single physical layer frame are generally described herein. Other embodiments may be described and claimed.

Method for aggregation of a number of media access control (MAC) frames into a single phyical layer frame in a distributed MAC layer

Embodiments of the present invention provide a method and apparatus for a multi-entity wireless communication adapter having a traffic management configuration to selectively associate at least first and second signal traffics corresponding to a basic service set station entity and an independent basic service set entity, respectively, with a shared physical layer which is able to process said first and second signal traffics. Additional features are described and claimed.

Method and apparatus of multi-entity wireless communication adapter

A word-based interface between a MAC and a PHY, allowing for variable pin counts, variable PHY and MAC data speeds, and variable numbers of connected PHYs. The word-based interface allows for the PHY to provide PHY-to-MAC words to the MAC, and for the MAC to provided MAC-to-PHY words to the PHY, where the PHY-to-MAC words are synchronized with the MAC-to-PHY words. Data and commands are provided in fields of the words, and may be time multiplexed over the interface. Circuits within the MAC and PHY allow for the MAC to detect if a PHY is present, the number of active pins, and the number of PHYs connected. The reset and synchronization signals are integrated into a single reset/sync signal. Identification data is exchanged between the MAC and PHY so that the proper device driver for the PHY may be loaded independently of the BIOS.
