An apparatus is provided that includes a processor, a memory controller coupled to the processor to provide access to a system memory, and an interface controller to communicate with an endpoint device. The interface controller is coupled to the processor and configured to access a register of the endpoint device, the register to be mapped into a memory space of the system, the register to store a service latency tolerance value of the endpoint device. The endpoint device has a service latency tolerance value for a first state and a service latency tolerance value for a second state. The service latency tolerance value for the first state is greater than the service latency tolerance value for the second state.

Downstream device service latency reporting for power management

An apparatus is provided that includes a transceiver to transmit and receive data between an upstream device and the apparatus, and further includes service latency reporting logic coupled to the transceiver to provide a service latency tolerance value of the apparatus to the upstream device, the service latency tolerance value corresponding to an activity state of the apparatus. The service latency tolerance value for an idle activity state can be greater than the service latency tolerance value for an active activity state.

Described herein are techniques related to near field coupling (e.g., wireless power transfers (WPF) and near field communications (NFC)) operations among others. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Coil and ferrite configuration to facilitate near field coupling

In accordance with various aspects of the disclosure, systems, methods, and devices are disclosed that include a power source integrated with a host computing device, and configured to provide power to the host computing device, and a wireless power transmission module coupled to the host computing device. The wireless power transmission module is configured to wirelessly transmit power derived from the power source independent of whether the host computing device is in a powered-off state or not. The host computing device may be configured to stop the wireless power transmission based on a determination that at least one of one or more predetermined transmission policies has been violated or that an unrecoverable error has occurred at the host computing device.

System integration of wireless power transmission subsystem

In accordance with various aspects of the disclosure, devices and methods are disclosed that include measuring, at a transmitter, a reflected power level corresponding to a specific transmit power level, and setting the transmit power to an operational level. At the transmitter, a new operational level of the transmit power may be determined, for example, by selecting at least one trial transmit power level, and based on reflected power levels measured corresponding to the operational level and the at least one trial level of the transmit power, either maintaining the operational level as the new operational level, or determining the at least one trial level as the new operational level. The operational transmit power level may correspond to a lowest reflected power level, or a highest rate of change of the reflected power level with respect to the transmit power level.

Dynamic wireless power control

In some embodiments, provided is a way for devices to request Six (or the like) entry and exit.

Systems and methods for implementing reduced power states

In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes features of a host computing device, and a wireless power transmission module and a wireless data transmission module both integrated on a circuit board of the host computing device. The host computing device is configured to transmit power and multi-media data to a peripheral device, upon receipt thereof from the wireless power transmission module and the wireless data transmission module, respectively. The peripheral device is configured to receive wirelessly power and multi-media data from a host computing device, and provide the received power and multi-media data to a wireless power reception module and a wireless data reception module, respectively, for processing, both modules being integrated on a circuit board of the peripheral device.

System integration supporting completely wireless peripheral applications

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.

In some embodiments, provided is a way for devices to request S0ix (or the like) entry and exit.
