SCHEDULED COEXISTENCE
First Claim
1. A method for scheduling transmissions from collocated Bluetooth device (BTD) and wireless local area network (WLAN) device, comprising the steps of:
- detecting a Bluetooth transmission, wherein said Bluetooth transmission comprises one or more quiet periods; and
scheduling a wireless local area network (WLAN) transmission, wherein frames of the WLAN transmission are received during said quiet periods of the Bluetooth transmission.

Abstract
The present invention provides a system and a method for improving the wireless local area network (WLAN) throughput performance in a collocated WLAN/Bluetooth system that uses packet traffic arbitration (PTA) to schedule WLAN and Bluetooth transmissions. The method includes detecting a Bluetooth transmission, where the Bluetooth transmission comprises one or more quiet periods; and scheduling a WLAN transmission, where frames of the WLAN transmission are received during the quiet periods of the Bluetooth transmission. The method according to the present invention allows the collocated WLAN to receive a frame send by the access point (AP) and acknowledge its reception without the AP reducing the data transmission rate due to unacknowledged frames. Also, the present invention discloses a mechanism where a collocated Bluetooth device (BTD) and WLAN device can communicate to the AP through a single antenna.
