According to one aspect of the invention, a method is provided in which a group of users in a system that employs a retransmission mechanism such as Automatic Repeat Request (ARQ) is divided into multiple sub-groups of users. Each user is assigned a number of channels for transmission of information. The number of channels assigned to each user is determined based, at least in part, on the number of the sub-groups and a number of channels available in the system. Transmission intervals are alternated among the multiple sub- groups such that only one of the sub-groups of users is allowed to transmit information during any transmission interval. An idle interval during which a particular user in the first group does not transmit information is used as a waiting period for acknowledgement of a previous transmission by the particular user.
Dans un aspect, l'invention concerne un proc~d~ dans lequel un groupe d'utilisateurs d'un systme utilisant un systme de retransmission tel qu'une demande de r~p~tition automatique (ARQ), est divis~ en de multiples sous-groupes d'utilisateur. A chaque utilisateur est attribu~ un nombre de canaux pour la transmission d'informations. Le nombre de canaux attribu~s ~ chaque utilisateur est d~termin~, au moins en partie, sur la base du nombre de sous-groupes et du nombre de canaux disponibles dans le systme. Les intervalles de transmission sont altern~s entre les multiples sous-groupes de sorte qu'un seul des sous-groupes d'utilisateurs est autoris~ ~ transmettre des informations pendant un intervalle de transmission. Un intervalle inoccup~, pendant lequel un utilisateur particulier du premier groupe ne transmet pas d'informations, est utilis~ comme p~riode d'attente d'un accus~ de r~ception relatif ~ une transmission pr~c~dente, mise en oeuvre par cet utilisateur.
