A dynamic temperature manager of a wireless system determines a threshold temperature defined by one or more operating parameters of the wireless system, the threshold temperature indicating a temperature in response to which power consumption of the wireless system is to be reduced. The dynamic temperature manager receives an indication of a temperature of the wireless system. A determination is made that the temperature exceeds the threshold temperature. The dynamic temperature manager provides an indication to cause a media access control (MAC) processing circuitry of the wireless system to adjust the one or more operating parameters of the wireless system to reduce the power consumption and the temperature of the wireless system based on the determination that the temperature exceeds the threshold temperature.

Managing and management of temperature of a wireless system

A wireless data transceiver includes a media access controller (MAC) configured to receive an inbound data packet from an air interface and to buffer the inbound packet for transport to a host, and to receive an outbound data packet from elsewhere in the transceiver and to transfer the outbound packet to the air interface. The transceiver further includes a host interface configured to receive the inbound packet transported from the MAC and to transfer the inbound packet to the host, and to receive the outbound packet from the host for transfer to the MAC. The transceiver also includes transport controller circuitry configured to execute instructions to generate and transfer management packets. In addition, the wireless data transceiver includes hardware data transport circuitry for transporting the inbound packet from the MAC to the host interface, and for transporting the outbound packet from the host interface to the MAC, without executing instructions.

Hardware data transport in wireless data transceiver

A filter expression is received at a wireless device assembly of a communication device. While a host assembly of the communication device is in a sleep mode, the wireless device assembly receives a signal having packet data, and determines whether the packet data contains a data pattern indicated by the filter expression. If the packet data contains the data pattern, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. If the packet data does not contain the data pattern, the wireless device assembly does not communicate the wakeup signal to the host assembly.

Memory efficient filtering

A host assembly of a wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.

Enhanced host sleep for WLAN devices

Methods and systems are described for providing Bluetooth and Wi-Fi coexistence on an electronic device. Aspects of exemplary embodiments include determining Bluetooth link parameters for a Bluetooth connection and Wi-Fi link parameters for a Wi-Fi connection. Also, a Bluetooth path loss for the Bluetooth connection and a Wi-Fi path loss for the Wi-Fi connection can be determined. According to this embodiment, one or more link conditions, based upon one or more of the Bluetooth link parameters, the Wi-Fi link parameters, the Bluetooth path loss, and the Wi-Fi path loss, may be calculated to determine if simultaneous collaboration between the Bluetooth connection and Wi-Fi connection is feasible. In response to simultaneous collaboration being feasible, the Bluetooth link parameters and the Wi-Fi link parameters are customized based on the one or more link conditions to permit simultaneous collaboration between the Bluetooth connection and the Wi-Fi connection.

Systems and methods for providing collaborative coexistence between bluetooth and Wi-Fi

In a method and apparatus for providing memory efficient filtering of a received broadcast signal, a wireless device assembly compares a filter expression to packet data in the broadcast signal to determine whether the packet data contains a particular bit pattern indicated by the filter expression. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. If the host assembly is in a sleep mode, and if the packet data contains the particular bit pattern indicated by the filter expression, the wireless device assembly communicates a wakeup signal to the host assembly for changing the host assembly from the sleep mode to an active mode. On the other hand, if the packet data does not contain the particular bit pattern indicated by the filter expression, the wireless device assembly does not communicate the wakeup signal to the host assembly.

USB self-idling techniques are described. In one or more embodiments, a Universal Serial Bus (USB) device comprises one or more modules to communicate via USB and self-idle by presenting an idle mode to a USB host and entering a suspend mode after the idle mode, the suspend mode being entered while the USB host is presented with the idle mode.

USB self-idling techniques

In a method and apparatus for providing memory efficient filtering of a received broadcast signal, filter expressions are compared to packet data in the broadcast signal and by a wireless device assembly to determine if a match exists. The wireless device assembly is able to perform such filtering with an associated host assembly in a sleep mode or with that host in an active mode. Upon finding a filter match, the wireless device assembly selectively communicates the received packet data to the host assembly for packet decoding and analysis. If the host assembly is in a sleep mode, the wireless device assembly may send a wakeup signal to the host assembly prior to transmitting the packet data.

A host assembly is communicatively coupled to a wireless device assembly via a first interface and via a second interface. A first signal is received at the wireless device assembly from the host assembly. The first signal indicates a request for the wireless device assembly to enter a host sleep mode of operation. In response to receiving the first signal, the wireless device assembly transmits a third signal to the host assembly, wherein the third signal indicates entry into the host sleep mode of operation. Subsequent to transmitting the third signal to the host assembly via the first interface, the wireless device assembly enters into the host sleep mode of operation. While in the host sleep mode of operation, the wireless device assembly transmits, via the second interface, the second signal, and, after transmitting the second signal to the host assembly, exits the host sleep mode of operation.

USB self-idling techniques are described. In one or more embodiments, a Universal Serial Bus (USB) device comprises one or more modules to communicate via USB and self-idle by presenting an idle mode to a USB host and entering a suspend mode while the USB host is presented with the idle mode.

In a method and apparatus for controlling operation of a wireless device, a host assembly of the wireless device enters into a handshaking procedure with firmware of the wireless device to initiate entry into or exit from a host sleep mode. Before such entry or exit, the handshaking procedure may require the host assembly to send an initiation handshake signal to the firmware, and require the firmware to send a confirmation handshake signal back to the host assembly. Entry or exit may be delayed until after the confirmation signal is received. The confirmation signal may vary depending on the handshaking configuration and activation data, and the confirmation signal may vary depending on whether the wireless device is in a power save mode or not.
