     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme to support a latency of no more than 10 millisecond (ms), for example, based on a determination that the application information  161  indicates that a low-latency application is to utilize the BT communications, as described below. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme to support a latency of no more than 5 ms, for example, based on a determination that the application information  161  indicates that a low-latency application is to utilize the BT communications, as described below. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme to support a latency of no more than 1 ms, e.g., no more than 0.8 ms, lesson more than 0.7 ms, or any other latency. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme to support a latency of no more than 1 ms, for example, based on a determination that the application information  161  indicates that a low-latency gaming application is to utilize the BT communications to communicate between the BT device  102  and a peripheral BT device, e.g., device  140 , as described below. 
     In some demonstrative aspects, BT controller  169  may be configured to identify a channel condition of a BT channel for performing the one or more BT activities, e.g., as described below. 
     For example, BT controller  169  may be configured to identify a channel condition of a BT channel for performing a BT a scan, and/or a channel condition of a channel for performing one or more BT communications with one or more other devices, e.g., with device  140 . 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme, for example, based on the channel condition, e.g., as described below. 
     In some demonstrative aspects, the channel condition may include a congestion level of the BT channel. 
     In one example, BT controller  169  may be configured to determine and/or monitor the congestion level of the BT channel, for example, based on a count of detected communications, e.g., BT communications by other BT devices, over the BT channel. 
     In another example, BT controller  169  may be configured to determine and/or monitor the congestion level of the BT channel, for example, based on a count of failed BT transmissions from BT device  102 . 
     In some demonstrative aspects, BT controller  169  may configure a duration of a BT scan interval for a BT scan over the BT channel, for example, based on the congestion level of the BT channel, e.g., as described below. 
     In some demonstrative aspects, BT controller  169  may dynamically configure the duration of the BT scan interval over the BT channel, for example, relative to the congestion level of the BT channel. For example, BT controller  169  may be configured to increase the duration of the BT scan interval, for example, based on a determination that the congestion level of the BT channel has increased; and/or to decrease the duration of the BT scan interval, for example, based on a determination that the congestion level of the BT channel has decreased. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme to support communication with a peripheral BT device, e.g., device  140 , for a low-latency application, for example, a low-latency gaming application, e.g., as described below. 
     For example, some peripheral devices, e.g., gaming devices, such as, a gaming mouse or any other gaming controller, may require relatively low latencies. For example, some gaming mice may not tolerate latencies of 70 ms. For example, many gaming mice may support latencies of about 1-2 ms. For example, some gaming mice may be configured to support latencies of even less than 1 ms. However, an actual latency of a wireless gaming mouse may increase, e.g., towards 70˜100 ms, for example, during periods of no mouse movement, e.g., since a USB transport may drop to a low power state, e.g., a “selective suspend” state, when there is no activity on the USB bus. In one example, the USB bus may be required to exit the low power state, for example, based on detected user activity of the mouse, thereby incurring a latency of 70˜100 ms. This latency may cause a poor user experience, for example, when, after a period of the mouse link being idle, the user suddenly moves the gaming mouse. This latency may result in degraded user experience, for example, in a use case of a sniper mode in first person shooter games. For example, wired USB mice and/or keyboards may not incur the selective suspend delay and therefore may be able to always meet latencies of less than 1 ms. 
     In another example, some peripheral devices, e.g., non-gaming devices, such as, a mouse or keyboard used for productivity applications, e.g., working on emails, spreadsheets, word processor documents, and the like, may be allowed to operate with an over the air latency typically between 7.5 ms and 11.25 ms, e.g., according to a Bluetooth protocol. However, in some cases and/or implementations over-the-air latency of 70˜100 ms may be unacceptable even for productivity use cases. Productivity mice and keyboard typically are compliant with the Bluetooth standard and can indeed support latencies around 10 ms. However, the user experience can suffer, for example, when the latencies jump to 70˜100 ms, e.g., due to the USB selective suspend state exit latency. 
     In some demonstrative aspects, BT controller  169  may be configured to selectively disable low power state, e.g., the USB selective suspend power state, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. 
     In some demonstrative aspects, BT controller  169  may be configured to identify, e.g., based on application information  161 , that a latency sensitive application is to be used by a user of device  102 , e.g., a latency sensitive game, such as a First-Person Shooter (FPS) game or any other application, is to be used by the user of device  102 . 
     In some demonstrative aspects, BT controller  169  may configure a BT communication link between BT device  102  and BT device  140 , for example, based on the determination that the latency sensitive application, e.g., the FPS game, is to be used by the user of device  102 . For example, BT controller  169  may configure the BT communication link between BT device  102  and BT device  140  according to a BT communication scheme, e.g., a “standards-plus” connection scheme, which may be configured to support a reduced latency, e.g., a latency of no more than 1 ms. For example, BT controller  169  may configure the BT communication link between BT device  102  and BT device  140  according to a BT communication scheme, which may utilize “standards-plus” connection intervals of as low as 1 ms. Accordingly, this BT communication scheme may provide a technical solution to allow the user of device  102  to use a gaming mouse with very low wireless communication latency, for example, while obviating a need to use an external USB dongle with the gaming mouse. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme for BT radio  114 , for example, based on the power state indication  165  and information regarding user activity of the user of device  102 , e.g., as described below. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme for BT radio  114 , for example, to support a reduced performance level and/or to consume less power, for example, based on a determination, that device  102  is operating at a battery-powered state and that no user activity is detected. 
     For example, BT controller  169  may determine that device  102  is operating at a battery-powered state, e.g., based on the power state indication  165 . 
     In one example, BT controller  169  may determine that there is no user activity or that there is only a reduced level of user activity, for example, based on a determination that no activity is detected by one or more Human Interface Devices (HIDs), e.g., a mouse, a keyboard, a gaming controller, or the like. For example, BT controller  169  may determine that there is no user activity or that there is only a reduced level of user activity, for example, based on a determination that no recent HID reports have been received. 
     In another example, BT controller  169  may determine that there is no user activity or that there is only a reduced level of user activity, for example, based on observation of the user, e.g., via a camera of device  102 , or any other input device. 
     In some demonstrative aspects, BT controller  169  may configure a BT communication link between BT device  102  and BT device  140 , for example, based on the determination that the latency sensitive application, e.g., the FPS game, is to be used by the user of device  102 , for example, while device  102  is currently wall-powered. For example, BT controller  169  may configure the BT communication link between BT device  102  and BT device  140  according to a low-latency mode, e.g., a low-latency BLE connection interval, for example, based on a determination that device  102  is currently wall-powered. 
     In some demonstrative aspects, BT controller  169  may dynamically reconfigure the BT communication link between BT device  102  and BT device  140 , for example, based the power state indication  165  and/or the application information  161 . 
     In some demonstrative aspects, BT controller  169  may dynamically self-configure the BT communication link between BT device  102  and BT device  140 , for example, for performance vs. power savings. 
     For example, BT controller  169  may configure the BT communication link between BT device  102  and BT device  140 , according to a low-power mode, which may be very power consumption sensitive, for example, based on a determination that power state indication  165  indicates that device  102  is battery-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     For example, BT controller  169  may configure the BT communication link between BT device  102  and BT device  140 , according to a high-performance mode, e.g., a low-latency mode, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and a determination that a low-latency application, e.g., a low-latency gaming application, is to utilize the BT communication link. 
     In some demonstrative aspects, BT controller  169  may configure the BT communication scheme for BT radio  114 , for example, by configuring a BT scan to be performed by BT radio  114 , e.g., as described below. 
     In some demonstrative aspects, BT controller  169  may configure a scan duty cycle of the BT scan, for example, based on the power state indication  165 , e.g., as described below. 
     In some demonstrative aspects, BT controller  169  may dynamically increase or decrease a scan duty cycle of the BT scan, for example, based on the power state indication  165 , e.g., as described below. 
     For example, BT controller  169  may set a first duty cycle (“high scan duty cycle”) for the BT scan, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. 
     For example, BT controller  169  may set a second duty cycle (“low scan duty cycle”) for the BT scan, e.g., lower than the high duty cycle, for example, based on a determination that power state indication  165  indicates that device  102  is battery-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     In one example, BT controller  169  may set a higher duty cycle LE scan, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     In one example, BT controller  169  may set a relatively low duty cycle scan, e.g., a duty cycle for scanning 10% of the time, for example, based on a determination that power state indication  165  indicates that device  102  is battery-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     In one example, BT controller  169  may set a relatively high duty cycle scan, e.g., a duty cycle for scanning at least 20% of the time or even more than 50% of the time, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. 
     For example, the ability to increase the scan duty cycle of the BT scan may provide technical benefits, for example, improved responsiveness and/or better user experience. 
     In some demonstrative aspects, BT controller  169  may selectively operate BT radio  114  at a low-power, low performance, receive mode, for example, based on the power state indication  165 , e.g., as described below. 
     For example, BT controller  169  may control and/or operate BT radio  114  at the low-power, low performance, receive mode, for example, based on a determination that power state indication  165  indicates that device  102  is battery-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     For example, BT controller  169  may select not to operate BT radio  114  at the low-power, low performance, receive mode, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. 
     In some demonstrative aspects, BT controller  169  may dynamically switch between low power and high performance modes of operation of BT radio  114 , for example, based on what BT profile is being used, and/or based on current link quality conditions. 
     In some demonstrative aspects, BT controller  169  may selectively enable BT communications for a High Accuracy Distance Measurement (HADM) functionality, for example, based on the power state indication  165 , e.g., as described below. 
     For example, BT controller  169  may disable BT communication of BT radio  114  for the HADM functionality, for example, based on a determination that power state indication  165  indicates that device  102  is battery-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     For example, BT controller  169  may enable BT communication of BT radio  114  for the HADM functionality, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. 
     In some demonstrative aspects, BT controller  169  may dynamically configure Received Signal Strength Indicator (RSSI) measurements on BT communications by BT radio  114 , for example, based on the power state indication  165 , e.g., as described below. 
     For example, BT controller  169  may set a first duty cycle (“high RSSI duty cycle”) for RSSI measurements, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. 
     For example, BT controller  169  may set a second duty cycle (“low RSSI duty cycle”) for RSSI measurements, e.g., lower than the high duty cycle, for example, based on a determination that power state indication  165  indicates that device  102  is battery-powered and/or that the charge level of the battery of BT device  102  is below a predefined threshold. 
     For example, increasing the RSSI duty cycle may allow performing more RSSI measurements, for example, to be able to better configure a scan duty cycle, and/or to determine more accurately levels of proximate interferers, which support Adaptive Frequency Hopping (AFH) channel classification. 
     In some demonstrative aspects, device  102  may utilize one or more algorithms, e.g., Transmit (Tx) Power Control (TPC) algorithms and/or Channel Quality Driven Data Rate (CQDDR) algorithms, which may be configured to request peer devices to transmit at higher power and/or lower modulation rates, for example, when the environment is congested. Accordingly, configuring device to operate at a “power hungry” mode, e.g., to frequently, or even constantly, measure the interference environment may be advantageous for performance of these algorithms. 
     In some demonstrative aspects, BT controller  169  may control and/or trigger AFH channel classification scans to run more frequently, for example, based on a determination that power state indication  165  indicates that device  102  is wall-powered, and/or that the charge level of the battery of BT device  102  is above a predefined threshold. For example, performing the AFH channel classification scans more frequently may improve reaction times to an environment with rapidly changing interference, e.g., due to the presence of many proximate WiFi networks and/or other interferers in the same frequency band. 
     In some demonstrative aspects, BT controller  169  may be configured to dynamically select operational modes of BT radio  114 , for example, based on estimating the number and/or intervals of advertisers in the vicinity of BT device, and/or based on estimating proximate interference traffic intensity and/or levels. 
     In some demonstrative aspects, BT controller  169  may be configured to autonomously control BT activities of BT device  102 , for example, by dynamically configuring high duty cycle scanning and/or other BT operations e.g., as described above. For example, at least some of these operations may be autonomously triggered and controlled by BT controller  169 , for example, independent of operations configured by host processor  166 . 
     In some demonstrative aspects, BT controller  169  may be configured to perform a handshaking procedure and/or a negotiation procedure with host processor  166 , for example, in order to coordinate and/or inform host processor  166  regarding these BT activities.

For example, one or more of the operations of the method of  FIG. 2  may be performed by one or more elements of a system, e.g., system  100  ( FIG. 1 ), for example, may be performed by a BT device, e.g., BT device  102  ( FIG. 1 ), and/or a controller, e.g., controller  124  ( FIG. 1 ) and/or BT controller  169  ( FIG. 1 ).

For example, BT controller  169  ( FIG. 1 ) may be configured to control one or more Bt activities of BT device  102 , for example, based at least on the power state indication  165  ( FIG. 1 ), e.g., as described above. 
     As indicated at block  206 , controlling the one or more BT activities of the BT device according to the BT communication scheme may include determining a selected BT scheme from a plurality of BT schemes, for example, based on the power state indication. For example, BT controller  169  ( FIG. 1 ) may be configured to determine the selected BT scheme from the plurality of BT schemes, for example, based on power state indication  165  ( FIG. 1 ), e.g., as described above. 
     As indicated at block  208 , controlling the one or more BT activities of the BT device according to the BT communication scheme may include configuring the BT communication scheme based on the selected BT scheme. For example, BT controller  169  ( FIG. 1 ) may be configured to configure the BT communication scheme based on the selected BT scheme, e.g., as described above.
