## Title
Apparatus, system and method of wireless communication during a power save state

## Abstract

Some demonstrative embodiments include apparatuses, systems, devices and/or methods of wireless communication during a power save state. For example, a wireless network interface may be configured to interface between a wireless communication device and a wireless network. The wireless network interface may include a controller to receive an indication of a power save state of the wireless communication device, and to generate an Information Element (IE) including Transmit (Tx) filter setup information defining allowed frames, which are allowed to be transmitted to the wireless communication device during the power save state; and a transmitter to transmit the IE via the wireless network.

## Background
TECHNICAL FIELD
Embodiments described herein generally relate to wireless communication during a power save state.
BACKGROUND
A mobile device may switch from an active power mode to a power save mode during one or more idle periods, for example, to reduce power consumption of the mobile device and to extend a battery life of a battery of the mobile device.
During the power save mode, the mobile device may power down main elements of the device, e.g., a processor, a display, a memory and/or any other power-consuming elements of the mobile device, while maintaining a network interface of the mobile device powered up.
The network interface may analyze and/or process incoming network traffic, and may wake-up the mobile device only when required, for example, based on one or more conditions defined by the mobile device.
Offloading the processing and/or the analyzing of the incoming traffic from the main elements of the mobile device to the network interface enables the mobile device to power down the main elements during the power save mode, and to reduce power consumption of the mobile device.

In some demonstrative embodiments, OS 125 may not power down wireless network interface 122 during the power save state, for example, to maintain connectivity to wireless network 103, and to enable device 120 to receive the allowed frames from network 103.
In some demonstrative embodiments, OS 125 may configure wireless network interface 122, e.g., via host interface 138, to wake up device 120 and to switch device 120 from the power save state to the active power state based on the predefined conditions.
In some demonstrative embodiments, wireless network interface 122 may be configured to wake up device 120, for example, if an allowed frame is received, e.g., by receiver 126.
In some demonstrative embodiments, wireless network interface 122 may be configured to determine whether or not a frame received by device 120 is an allowed frame.
For example, wireless network interface 122 may be configured to handle, process, and/or analyze frames received via wireless network 103, e.g., to determine whether or not a frame received by device 120 is an allowed frame.
In some demonstrative embodiments, wireless network interface 122 may be configured to perform one or more functionalities of one or more elements of device 120, during the power save state, for example, to determine whether or not a frame received by device 120 is an allowed frame, for example, while processor 191, memory 194 and/or one or more other elements of device 120 are powered down.
In some demonstrative embodiments, wireless network interface 122 may include a receive (RX) filter module 137 configured to filter frames received by receiver 126 via wireless network 103.
In some demonstrative embodiments, wireless network interface 122 may configure RX filter module 137 based on the wake-up conditions, for example, to process and provide to OS 125 only the allowed frames.

RX filter module 137 may provide the allowed frame to OS 125 via network interface 138, for example, for further processing and/or handling.
In some demonstrative embodiments, waking up device 120, for example, only upon receiving an allowed frame, may enable device 120 to save power while maintaining responsiveness to communications from wireless network 103.
In one example, OS 125 may configure wireless network interface 122 to receive frames, which are directed to an Email application installed on device 120. According to this example, OS 125 may switch device 120 to the power save mode, and network interface 122 may wake-up device 120, for example, only if receiver 126 receives an allowed frame, e.g., a new Email from network 103. Waking up device 120, for example, only upon receiving an allowed frame, may enable device 120 to save power and to maintain responsiveness to Email communications from wireless network 103.
In some demonstrative embodiments, a wireless communication device in wireless network 103, e.g., device 140, may continue to transmit to device 120 frames, which are not allowed to be received by the device 120 (“non-allowed frames”), for example, if device 140 is not aware that device 120 is at the power save state.
In some demonstrative embodiments, device 140 may continue to transmit the non-allowed frames to device 120, for example, if device 140 is not aware, which frames are allowed to be received by device 120, e.g., according to the wake-up conditions of OS 125.
In some demonstrative embodiments, device 140 may continue to transmit the non-allowed frames to device 120, for example, if device 120 does not advertise, which frames are allowed to be received by device 120, and/or if device 120 does not advertise that device 120 is at the power save state.
In some demonstrative embodiments, a power consumption of device 120 may increase during the power save state, for example, if receiver 126 receives the non-allowed frames, and/or network interface 122 processes and/or handles the non-allowed frames, for example, to determine whether or not to wake-up device 120.
Some demonstrative embodiments may enable device 120 to advertise the power state of device 120, waking up filter conditions of RX filter module 137, and/or a setup of wireless communication link 135 during the power save state of device 120, e.g., as described below.
Some demonstrative embodiments may enable device 140 to determine which frames are to be transmitted to device 120, and how to transmit the frames to device 120 during the power-save state of device 120, e.g., as described below.
In some demonstrative embodiments, the power consumption of device 120 and/or 140 may be reduced, for example, if device 140 may transmit frames, which match the wake-up filter conditions and/or using the setup of wireless communication link 135.
In some demonstrative embodiments, wireless network interface 122 may include a controller 134 to receive an indication of a power save state of wireless communication device 120.
In some demonstrative embodiments, controller 134 may receive the power save state from OS 125, for example, via host interface 138.
In some demonstrative embodiments, controller 134 may receive from OS 125 configuration information of wireless communication device 120 during the power save state.
In some demonstrative embodiments, controller 134 may generate an Information Element (IE) including information relating to the power state of device 120.
