CA 2558531

A system and method is provided for incorporating host-device communication in wireless IJSB (WUSB). A host (101) either uses a multicast Distributed Reservation Protocol (DRP) frame on behalf of connected devices (102) to reserve wireless channel resources, a unicast DRP frame or Enhanced Distributed Channel Access (EDCA) with a Poll Frame. In the case of a unicast DRP frame the number of unicast frames sent for reservation depends on the number of connected devices (102).

La présente invention concerne un système et procédé permettant d'intégrer à l'USB radio (WUSB) la communication entre hôte et terminal. Un hôte (101) utilise soit une trame DRP (Distributed Reservation Protocol) multidiffusion pour le compte de terminaux connectés (102) pour réserver des ressources de canaux radio, soit une trame DRP diffusion unique, soit l'EDCA (Enhanced Distributed Channel Access) avec trame de consultation (Poll Frame). Dans le cas de la trame DRP diffusion unique, le nombre de trames diffusion unique envoyées pour réservation dépend du nombre de terminaux connectés (102).
