Method and system for sharing a single antenna on platforms with collocated Bluetooth and IEEE 802.11 b/g devices

摘要

A method and system for sharing a single antenna on platforms with collocated Bluetooth and IEEE 802.11 b/g devices are provided. A single antenna may be utilized for communication of Bluetooth HV3 frame traffic and wireless local area network (WLAN) communication based on a time multiplexing approach. At least one antenna switch may be utilized to configure an antenna system to enable Bluetooth and WLAN coexistence via the single antenna. Configuration signals may be generated by a Bluetooth radio device and/or by a WLAN radio device to configure the antenna system. A default configuration for the antenna system may provide WLAN communication between a station and a WLAN access point until Bluetooth communication becomes a priority.

1. A method for providing wireless communication, the method comprising:
in a station that handles at least a Bluetooth (BT) communication protocol and a Wireless Local Area Network (WLAN) communication protocol:
asserting a BT priority signal with a time duration that includes a guard time, wherein a start time of the time duration is a start time of the guard time;configuring said station to provide BT communication via a single antenna based on said BT priority signal, wherein a first antenna switch and a second antenna switch are configured for using said single antenna for BT and WLAN communication;determining whether WLAN data communication occurs during the guard time;terminating the WLAN data communication between the start time and an end time of the guard time when the WLAN data communication is determined to occur during the guard time; andcommunicating BT data via said single antenna while said BT priority signal is asserted between a BT radio and a WLAN radio but subsequent to the end time of the guard time associated with the BT priority signal, wherein the BT priority signal is separate from the BT data.
