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.

摘要： Collaborative coexistence of co-located mobile WiMAX, wireless LAN, and/or Bluetooth radios. Within a communication device that includes multi-protocol communication capability, the various radio modules included within such a communication device operate cooperatively such that collisions are avoided between those various radios. When a first of the radio modules operates as governed by a relatively rigid frame structure, a second of the radio modules capitalizes upon that predetermined nature (of the relatively rigid frame structure) to support communication during times in which that first radio module has a lower level of activity (e.g., turned off completely, within a power savings mode, in a sleep mode, etc.). The radio module operation is performed within a time-orthogonal manner, such that multiple radio modules are not attempting to transmit or receive simultaneously. Moreover, CTS2SELF operation can be employed alone or in conjunction with power savings operation of co-located radios within a communication device.
