Abstract
A system and method of permitting coexistence of WiFi and Bluetooth® data transfer on a single chip in UE including a transceiver includes using CTS data packets to protect Bluetooth® signals for SCO communication links; using only WiFi circuitry in the chip to determine when Bluetooth® data transfer is required by the UE; establishing a specified period of the Bluetooth® data transfer; and starting WiFi medium contention only upon an end of the specified period of the Bluetooth® data transfer on the single chip. The power save mode of the WiFi circuitry may be used with Bluetooth® ACL data packets in WiFi periodic data transfer gaps. The WiFi data transfer has no timing constraints, whereas the Bluetooth® data transfer has timing constraints and can only occur during the specified period. The WiFi data transfer does not occur when the Bluetooth® data transfer is occurring.
