Title (EN) APPARATUS AND METHOD FOR PRIORITIZATION OF RANDOM ACCESS IN A MULTI-USER WIRELESS COMMUNICATION SYSTEM
(FR) APPAREIL ET PROCÉDÉ DE PRIORISATION D'ACCÈS ALÉATOIRE DANS UN SYSTÈME DE COMMUNICATION SANS FIL À UTILISATEURS MULTIPLES
Abstract:
(EN) The present disclosure relates to the prioritization of devices taking part in a multi-user random access wireless communication. Based on some known conditions, devices that comply with the conditions are given preferential treatment during the random access period. The preferential treatment may refer to the eligible devices being allowed to access more resource units during the random access, or it may also mean faster access to the medium during the random access. By taking advantage of the methods described in the present disclosure, it is possible to assign higher priority to selected frame types and/or device categories in a multi-user random access wireless communication system.
(FR) La présente invention concerne la priorisation de dispositifs intervenant dans une communication sans fil d'accès aléatoire à utilisateurs multiples. En fonction de certaines conditions connues, des dispositifs respectant les conditions reçoivent un traitement préférentiel pendant la période d'accès aléatoire. Le traitement préférentiel peut correspondre à l'autorisation pour des dispositifs éligibles d'accéder à davantage d'unités de ressource durant l'accès aléatoire ou peut également signifier un accès plus rapide au support pendant l'accès aléatoire. Grâce aux procédés décrits dans la présente invention, il est possible d'attribuer une priorité plus élevée à des types de trame sélectionnés et/ou des catégories de dispositifs dans un système de communication sans fil d'accès aléatoire à utilisateurs multiples.
