Abstract: 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.

Abstract: A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.

The first radio module may be configured to generate a collocated radio tolerance indicator that indicates a tolerance of the first radio module to interference caused by the collocated second radio module when the collocated second radio module is transmitting, and provide the collocated radio tolerance indicator to a host processor when a second collocated radio module is transmitting. The host processor may be configured to control the second radio module based at least in part on the collocated radio tolerance indicator.

Abstract: Methods and systems for enabling coexistence of multiple potentially interfering wireless components in a device are provided. A device may include a wireless module using a proprietary protocol and one or more modules using standardized protocols. The device further includes a coexistence arbitration module configured to arbitrate access to a shared communication medium among the wireless modules based on assertion of medium access requests by the modules and the associated priority of the asserted medium access requests. When multiple medium access requests have the same priority, precedence for access to the shared medium is determined based on additional criteria. The coexistence arbitration module may be a separate module or may be integrated into another module or distributed among the modules. The device may include a host processor for altering transmission characteristics of a module to increase the likelihood that another module can receive data within a reasonable time period.

Abstract: A coexistence signaling scheme for radio communications is described. In one embodiment, a method for coexistence signaling includes establishing first communications and second communications with separate access points or base stations. The method further includes determining protocol timings of the first and second communications. Based on various communications parameters, protocol timings, and identified interference conditions, the method includes generating one or more priority signals to manage the first and second communications. According to certain aspects, overlapping channel conditions can be avoided while maintaining acceptable communications data throughput.
