Title
(EN) ENHANCED TRIGGER FRAME BASED DISCOVERY FOR A NEIGHBOR AWARENESS NETWORK
(FR) DÉCOUVERTE EN FONCTION D'UNE TRAME DE DÉCLENCHEMENT AMÉLIORÉE POUR UN RÉSEAU SENSIBLE AU VOISIN
Abstract
(EN) When a first node cannot hear a second node, the second node is "hidden" to the first node. In response to receiving a trigger frame, the two nodes may inadvertently transmit response frames at approximately the same time. The response frames may collide with each other, thereby causing delays in node discovery in a NAN. Provided herein are methods, apparatuses, and computer program products for reducing collisions in wireless communication. In some configurations, nodes may receive trigger frames that indicate a reduction in the rate that response frames are transmitted when traffic load conditions are high. In some configurations, nodes located in different coverage areas (e.g., a "hidden area" and a "non-hidden area") may transmit response frames at different times. In some configurations, the nodes may refrain from transmitting their response frames upon hearing that another node having a higher serving preference rank is transmitting.
(FR) Selon l'invention, lorsqu'un premier nœud ne peut pas entendre un second nœud, le second nœud est "caché" au premier nœud. En réponse à la réception d'une trame de déclenchement, les deux nœuds peuvent transmettre par inadvertance des trames de réponse approximativement en même temps. Les trames de réponse peuvent entrer en collision les unes avec les autres, permettant ainsi de provoquer des retards dans la découverte de nœud dans un NAN. La présente invention concerne des procédés, des appareils et des produits programme d'ordinateur pour réduire les collisions dans une communication sans fil. Dans certaines configurations, les nœuds peuvent recevoir des trames de déclenchement qui indiquent une réduction du débit auquel des trames de réponse sont transmises lorsque des conditions de charge de trafic sont élevées. Dans certaines configurations, des nœuds situés dans des zones de couverture différentes (par exemple une "zone cachée" et une "zone non cachée") peuvent transmettre des trames de réponse à différents instants. Dans certaines configurations, les nœuds peuvent s'abstenir de transmettre leurs trames de réponse lorsqu'ils entendent qu'un autre nœud, ayant un rang de préférence de desserte plus élevé, est en cours de transmission.
