Embodiment Construction

[0050] The present invention provides a method and device for cooperative coexistence of Bluetooth and IEEE 802.11g wireless local area network (WLAN) technologies when they are combined on a system-on-chip (SOC) device. Within a single integrated circuit (IC) that handles both Bluetooth and WLAN technologies, WLAN priority can be selected for WLAN transfers, and Bluetooth priority can be selected for Bluetooth transfers. WLAN and Bluetooth priorities can be selected from multiple priorities. A Packet Transmission Scheduler (PTS) schedules the transmission of WLAN and Bluetooth signals according to selected priorities. In some cases, the PTS may increase or decrease the priority of WLAN and / or Bluetooth transmissions based on information volume needs.

[0051] Figure 1A is a block diagram of a WLAN infrastructure network including Basic Service Sets (BSSs) and using a generic Distributed System (DS) according to one embodiment of the present invention. refer to Figure 1A ,...

Abstract

The invention discloses a method and a device for co-existing between bluetooth and IEEE 802.11g when both technologies are integrated on a system-on-a-chip (SOC for short) device. WLAN priority can be selected for WLAN transfers and Bluetooth priority can be selected for Bluetooth transfers in a single integrated circuit that handles both Bluetooth and WLAN technologies. WLAN and Bluetooth priorities can be selected from multiple priorities. A Packet Transmission Scheduler (PTS) schedules the transmission of WLAN and Bluetooth signals according to selected priorities. In some examples, the PTS may increase or decrease the priority of WLAN and / or Bluetooth transmissions based on traffic requirements.

Description

technical field [0001] The present invention relates to communication systems, and more particularly to a method and method for cooperative coexistence between Bluetooth and IEEE 802.11g when both technologies are integrated on a system-on-a-chip (SOC) device. equipment. Background technique [0002] The use of wireless personal area networks (WPANs) has gained popularity in a wide range of applications because of the flexibility and convenience of connectivity. WPAN systems, such as those based on Class 2 Bluetooth (Class2BT) technology, replace cumbersome cables and / or electric wire. However, for very few applications, the higher power class 1 BT devices can operate within 100 meters. In contrast to WPAN systems, wireless local area networks (WLANs) can provide connectivity of devices within a larger geographical area, such as the coverage of buildings or campuses. The WLAN system is based on the IEEE802.11 standard specification, generally works within a range of 100 ...
