(FR) COMMUNICATIONS COOPERATIVES MULTICELLULAIRES DANS UN RESEAU DECENTRALISE
Abstract
(EN)
Method of multicell cooperative radio communications in which: the terminals estimate and communicate to all the access points of a cooperating group of access points information about the transmission channels between them and each access point of the group, the access points have homologous means of processing for ordering the servicing of the terminals and operate according to a determined criterion common to all the access points, the servicing of the terminals is performed jointly by the access points, in an order determined by said processing means, using transmission parameters on the basis of the information about the transmission channels which is transmitted by the terminals.
