Title
(EN) COMMUNICATION DEVICES AND COMMUNICATION METHODS FOR MULTI-BAND TRAFFIC STREAMS
(FR) DISPOSITIFS DE COMMUNICATION ET PROCÉDÉS DE COMMUNICATION POUR FLUX DE TRAFIC MULTI-BANDES
Abstract
(EN)
Communication devices and methods for multi-band traffic streams are provided. One exemplary embodiment provides a multi-band communication device which includes at least a plurality of transceivers and Media Access Control (MAC) circuitry. In operation, the transceivers each transmit signal frames on different ones of a plurality of frequency bands. The MAC circuitry is coupled to the transceivers and, in operation, receives a multi-band block acknowledgement frame on one of the plurality of frequency bands acknowledging the signal frames transmitted on the plurality of frequency bands. Another exemplary embodiment provides MAC circuitry which in operation generates and transmits a multi-band block acknowledgement frame on one of the plurality of frequency bands acknowledging the signal frames received on the plurality of frequency bands.

L'invention concerne des dispositifs et des procédés de communication pour des flux de trafic multi-bandes. Un mode de réalisation donné à titre d'exemple concerne un dispositif de communication multibande qui comprend au moins une pluralité d'émetteurs-récepteurs et des circuits de commande d'accès au support (MAC). En fonctionnement, les émetteurs-récepteurs émettent chacun des trames de signaux sur différentes bandes de fréquence d'une pluralité de bandes de fréquences. Le circuit MAC est couplé aux émetteurs-récepteurs et, en fonctionnement, reçoit une trame d'accusé de réception de bloc multibande sur l'une de la pluralité de bandes de fréquences accusant réception des trames de signaux transmises sur la pluralité de bandes de fréquences. Un autre mode de réalisation donné à titre d'exemple concerne un circuit MAC qui, en fonctionnement, génère et transmet une trame d'accusé de réception de bloc multibande sur l'une de la pluralité de bandes de fréquence accusant réception des trames de signaux reçues sur la pluralité de bandes de fréquence.
