Abstract: A method for transmitting one or more first wireless local area network (WLAN) packets and one or more first Bluetooth (BT) packets. The method includes: prior to transmission of the one or more first wireless local area network (WLAN) packets, predicting a first time at which the transmission of the one or more first wireless local area network (WLAN) packets is going to end, and predicting a second time at which reception of one or more second Bluetooth (BT) packets is going to start; and simultaneously transmitting the one or more first wireless local area network (WLAN) packets and the one or more first Bluetooth (BT) packets in response to the first time being predicted to occur prior to the second time.

Abstract: Bluetooth and wireless LAN arbitration is described. In embodiments, a communication device includes a Bluetooth device for Bluetooth communication according to Bluetooth protocol, and includes a wireless LAN device for network communication according to wireless network protocol. An antenna switching circuit connects the Bluetooth device to an antenna for the Bluetooth communication, and connects the wireless LAN device to the antenna for the network communication. An arbitration control system arbitrates when the Bluetooth device is connected to the antenna via the antenna switching circuit and when the wireless LAN device is connected to the antenna via the antenna switching circuit.

Abstract: A wireless network device including an antenna, a first communication module, and a second communication module. The first communication module is configured to transmit or receive packets of data in accordance with a first communication standard, and the second communication module is configured to transmit or receive packets of data in accordance with a second communication standard. The wireless network device further includes an arbitration module configured to grant access of each of the first communication module and the second communication module to the antenna so that the first communication module and the second communication module can respectively transmit or receive data packets in accordance with the first communication protocol and the second communication protocol.

Abstract: A radio frequency front-end includes a first path, second path, and third path each coupled between an antenna and a transceiver. The first path is configured to convey WLAN signals from the transceiver to the antenna for transmission. The second path is configured to convey received Bluetooth signals and received WLAN signals from the antenna to the transceiver. The third path is configured to convey Bluetooth signals from the transceiver to the antenna for transmission when a WLAN link is active and not in a power save state, and is configured to convey received Bluetooth signals from the antenna to the transceiver, and Bluetooth signals from the transceiver to the antenna for transmission, when the WLAN link is either inactive or in the power save state.

Abstract: A radio frequency (RF) front-end configured to share transmissions and receptions of Bluetooth signals and WLAN signals. In an exemplary embodiment, the RF front-end comprises a first path coupled between an antenna and a transceiver dedicated to transmissions of the WLAN signals; a second path coupled between the antenna and the transceiver dedicated to simultaneous receptions of the Bluetooth signals and the WLAN signals; and a third path coupled between the antenna and the transceiver. The third path may be dedicated to transmissions only of the Bluetooth signals when a WLAN link is active; and transmissions and receptions of the Bluetooth signals when the WLAN link is active and in a power save state, and when the WLAN link is inactive.

Abstract: A beginning of a Bluetooth inquiry phase or a Bluetooth paging phase is determined. In response to determining that the Bluetooth inquiry phase or the Bluetooth paging phase is beginning, a power save (PS) mode signal is sent from a first device to a second device via a wireless local area network (WLAN) communication link, wherein the PS mode signal indicates that the first device is in a WLAN PS mode. A PS poll signal is sent from the first device to the second device via the WLAN communication link in a gap between Bluetooth inquiry phase message transmissions during the Bluetooth inquiry phase or between Bluetooth paging phase message transmissions during the Bluetooth paging phase.

Abstract: Circuits, architectures, systems, methods, algorithms, and software and/or firmware for arbitrating media access requests from multiple wireless communication protocol components. Exemplary circuits include a request processing circuit configured to set a positive media access grant output for a first one of the wireless component before entering a power saving mode of operation, determine a waking media access state of the first wireless component while exiting the power saving mode of operation, and process media access requests from the wireless components the waking media access state of the first wireless component. Embodiments of present invention advantageously provide for more reliable arbitration of media access requests from multiple wireless communication protocol components during and after power saving modes of operation.

Abstract: A wireless network device includes a first communication module to communicate with at least one of first devices and a second communication module to communicate with at least one of second devices. An arbitration module receives a request for communication from the first communication module, detects when the second communication module is communicating in a locked mode, and denies request for communication from the first communication module when the second communication module is communicating in the locked mode. Transmission or reception of a packet in the locked mode is not interrupted to avoid loss of the packet. The arbitration module grants the request for communication from the first communication module when the second communication module is communicating in the locked mode and when granting the request for communication from the first communication module does not require stopping the second communication module from communicating in the locked mode.
