Title (EN) METHOD OF WIRELESS LOCAL AREA NETWORK AND BLUETOOTH NETWORK COEXISTENCE IN A COLLOCATED DEVICE
(FR) PROCEDE DE COEXISTENCE D'UN RESEAU LOCAL SANS FIL ET D'UN RESEAU BLUETOOTH DANS UN DISPOSITIF COLOCALISE
Abstract: front page image
(EN)A collocated wireless local area network/Bluetooth (WLAN/BT) device (10) avoids radio interference between the two wireless systems by collaborative coexistence mechanisms. The collocated WLAN/BT device and coexistence methods include time division multiplexing based on various operating states of the collocate WLAN (20) and BT (30) systems, respectively. Such operating states include the transmission of low priority WLAN and BT data signals during W L A N and BT periods, the sleep mode of the collocated WLAN system, transmission of high priority data signals from the collocated BT system during time division multiplexed WLAN and BT periods, the transition of the collocated BT system from an active state to an idle state, and the transition of the collocated WLAN system from an active state to an idle state.
(FR)L'invention concerne un dispositif (10) colocalisé d'un réseau local sans fil/bluetooth (WLAN/BT), lequel permet d'éviter des interférences radio entre les deux systèmes sans fil au moyen de mécanismes de coexistence collaboratifs. Ce dispositif colocalisé WLAN/B et ces procédés de coexistence comprennent le multiplexage par répartition dans le temps basé sur divers états de fonctionnement des systèmes colocalisés WLAN (20) et BT (30) respectivement. De tels états de fonctionnement comprennent la transmission de signaux de données WLAN et BT de faible priorité durant des périodes WLAN et BT, le mode sommeil du système colocalisé WLAN, la transmission de signaux de données haute priorité du système colocalisé BT durant des périodes WLAN et BT multiplexées par répartition dans le temps, la transition du système colocalisé BT d'un état actif à un état d'arrêt et la transition du système colocalisé WLAN d'un état actif à un état d'arrêt.
