Title
(DE) SELEKTIVE WEITERLEITUNG VON DATENPAKETEN
(EN) SELECTIVE RELAY OF DATA PACKETS
(FR) RELAIS SÉLECTIF DE PAQUETS DE DONNÉES
Abstract
(EN) The disclosure relates generally to wireless communication, and more particularly to selective relay of data packets. A method includes listening to a host device in one or more listening time slots of a host piconet, identifying one or more bitmap portions of a bitmap, wherein the identified one or more bitmap portions corresponds to the one or more listening time slots of the host piconet, determining whether a data packet having a data packet payload is effectively received from the host device during the one or more listening time slots, and populating the bitmap with one or more corresponding signifiers.
(FR) L'invention concerne d'une manière générale la communication sans fil, et plus particulièrement le relais sélectif de paquets de données. Un procédé consiste à écouter un dispositif hôte dans un ou plusieurs créneaux temporels d'écoute d'un picoréseau hôte, à identifier une ou plusieurs parties de table de bits d'une table de bits, ladite partie de table de bits identifiée correspondant audit créneau temporel d'écoute du picoréseau hôte, à déterminer si un paquet de données ayant une charge utile de paquet de données est reçu de manière efficace à partir du dispositif hôte pendant ledit créneau temporel d'écoute, et à peupler la table de bits à l'aide d'un ou plusieurs signifiants correspondants.
