Abstract

La présente demande concerne un procédé de communication sans fil et un appareil de communication. Le procédé comprend : la détermination, par un dispositif de communication, de premières informations de commande pour programmer des premières données, les premières informations de commande comprenant un premier champ et un second champ, le premier champ comprenant M bits, lorsque le premier champ indique une première valeur d'état, le premier champ étant utilisé pour indiquer des premières informations de programmation des premières données, et lorsque N bits dans le premier champ indiquent une seconde valeur d'état, au moins un bit dans le second champ et/ou des bits autres que les N bits dans le premier champ étant utilisés pour indiquer les premières informations de programmation, N et M étant des entiers positifs, et N étant inférieur ou égal à M ; et la réception ou l'envoi, par le dispositif de communication, des premières données selon les premières informations de commande, ce qui améliore la flexibilité pour indiquer les informations de commande sans augmenter le nombre de bits des informations de commande.
