Problems solved by technology

However, these technologies primarily address coexistence between WLAN and BT devices, not between WLAN and / or BT devices and devices using proprietary wireless protocols or other standards
Therefore, these cooperative techniques may reduce the efficiency of the transfer, or require the use of additional hardware resources

Embodiment Construction

[0078] FIG. 1 is a schematic structural diagram of an exemplary system 100 with a station or terminal 140 capable of supporting the coexistence of multiple wireless modules that may interfere with each other according to an embodiment of the present invention. A station or terminal 140 (hereinafter referred to simply as "station 140") includes multiple wireless modules 142a-c that operate in the same frequency band or in mutually interfering frequency bands. For example, the wireless module 142a can be a wireless local area network (WLAN) module (such as using a WLAN protocol based on the IEEE 802.11 standard), the wireless module 142b can be a wireless personal area network (WPAN) device (such as based on a Bluetooth protocol), and the wireless module 142c can be It is a wireless transceiver device based on a dedicated wireless protocol. Those skilled in the art should understand that other or optional wireless modules may also be included in the station 140 . For ease of de...

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.

Description

technical field [0001] The present invention relates to a wireless multimedia platform, and more specifically, relates to arbitration for accessing media between wireless modules. Background technique [0002] The application of various wireless technologies has become very popular. Wireless Personal Area Networks (WPANs), such as those using Bluetooth technology, provide methods for connecting peripherals and mobile devices over short distances. Wireless Local Area Networks (WLANs) provide means for mobile devices to connect wirelessly to networks, such as Local Area Networks (LANs), over long distances. Many WLAN systems are based on the IEEE 802.11 WLAN standard. Additionally, many devices, such as wireless transceivers, can communicate using suitable wireless protocols. [0003] In many cases, a single UE may use multiple wireless technologies. For example, Bluetooth technology can be used to connect headphones, WLAN technology can be used to connect devices to a net...
