Abstract
(EN)
Techniques for acknowledging communications from multiple devices are described herein. For example, a device may broadcast a group acknowledgement message indicating that communications from multiple devices have been received by the device. Each acknowledgement in the group acknowledgement message may include a device identifier for a device that sent a communication (e.g., a Medium Access Control (MAC) address of the device, a hash of the MAC address of the device, etc.) and a communication identifier for the communication (e.g., a sequence number of the communication, a Cyclic Redundancy Check (CRC) code for the communication, etc.).
(FR)
L'invention concerne des techniques pour accuser réception de communications à partir d'une pluralité de dispositifs. Par exemple, un dispositif peut diffuser un message d'accusé de réception de groupe indiquant que des communications ont été reçues par le dispositif à partir d'une pluralité de dispositifs. Chaque accusé de réception dans le message d'accusé de réception de groupe peut comprendre un identificateur de dispositif pour un dispositif qui a envoyé une communication (par exemple, une adresse de contrôle d'accès au support (MAC) du dispositif, un hachage de l'adresse MAC du dispositif, etc.), et un identificateur de communication pour la communication (par exemple, un numéro de séquence de la communication, un code de vérification à redondance cyclique (CRC) pour la communication, etc.).
