摘要： Methods and systems for collaborative coexistence of Bluetooth and WiMax are disclosed. Aspects of one method may include a packet traffic arbiter (PTA) in a mobile terminal that arbitrates among requests to transmit from one or more communication devices collocated in the mobile terminal. The communication devices may comprise, for example, a WLAN communication device, a WiMax communication device, and/or a Bluetooth communication device. The arbitration may be based on, for example, whether a packet will be received by one of the plurality of collocated communication devices at a time of transmission of the present data packet and/or a priority for data to be transmitted. An exemplary scenario may be where a Bluetooth headset may be used for communication over a WiMax voice connection. One arbitration method may comprise allowing the WiMax packet to be transmitted, and replacing the received Bluetooth packet with data indicating silence. Another method may comprise not allowing transmission of the present WiMax packet. Rather, the present WiMax packet and a subsequent WiMax packet may e transmitted at the next transmission period.

摘要： Certain embodiments of the invention may be found in a method and system for antenna and radio front-end topologies for a system-on-a-chip (SOC) device that combines Bluetooth and IEEE 802.11 b/g WLAN technologies. A single chip radio device that supports WLAN and Bluetooth technologies receives a WLAN signal in a WLAN processing circuitry of the radio front-end and in a Bluetooth processing circuitry of the radio front-end. Signals generated by the WLAN processing circuitry and the Bluetooth processing circuitry from the received WLAN signal may be combined in a diversity combiner that utilizes selection diversity gain combining or maximal ratio combining (MRC). When a generated signal is below a threshold value, the signal may be dropped from the combining operation. A single antenna usage model may be utilized with the single chip radio device front-end topology to support WLAN and Bluetooth communications.
