Problems solved by technology

Frames with lower data rates are more likely to be corrupted by bluetooth put together, which makes it more likely that the access point will further reduce its data rate

Embodiment Construction

[0021] Various modifications and alternative forms may be made to the invention, some of which have been shown by way of example in the drawings and which have been described in detail. It should be understood, however, that the invention is not limited to the particular embodiments described. On the contrary, the invention covers all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims.

[0022] figure 1is a flowchart illustrating a method of scheduling transmissions from a co-located Bluetooth device (BTD) and a WLAN device according to an example embodiment of the present invention. After the transmit and receive cycles, Bluetooth transmissions have one or more silent periods. WLAN transmissions are adjusted in such a way that frames for WLAN transmissions are received during the Bluetooth silent period. Before scheduling the WLAN transmission, the type of link on which the Bluetooth transmissi...

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.

Description

technical field [0001] The present invention relates generally to wireless communications, and more particularly to scheduling transmissions from co-located Bluetooth devices (BTD) and wireless local area network (WLAN) devices. Background technique [0002] Today, the use of wireless personal area networks (WPANs) has gained popularity due to the flexibility and convenience in connectivity provided by them. A WPAN system, such as a WPAN based on Bluetooth technology, provides a wireless connection with a peripheral device and / or a mobile terminal by providing a short-range wireless link capable of connecting within a certain range (10 meter range). Unlike WPAN systems, wireless local area networks (WLANs) can provide connectivity for devices located within a somewhat larger geographic area, such as the area covered by a building or campus. WLAN systems are based on the IEEE 802.11 standard specification, typically operate within a range of 100 meters, and are generally use...
