Title (EN) METHOD AND SYSTEM OF THRESHOLD SELECTION FOR RELIABLE RELAY STATIONS GROUPING FOR DOWNLINK TRANSMISSION
(FR) PROCÉDÉ ET SYSTÈME DE SÉLECTION DE SEUIL POUR UN GROUPEMENT DE STATIONS RELAIS FIABLE POUR UNE TRANSMISSION DE LIAISON DESCENDANTE
Abstract: front page image
(EN)A relaying selection and cooperative communications method provides a threshold selection criterion for forming a reliable group of relay stations (RSs) based on one or more design criteria. Possible design criteria include an outage probability constraint and a throughput constraint. The threshold value is selected according to, for example, transmission paths (e.g., line-of-sight, obstructed-light-of-sight, non-light-of-sight) or channel conditions (e.g., signal-to-noise-ratio) between the base station (BS) and the RSs (i.e., BS-RSs link) and between the RSs and the mobile station (MS) (i.e., RSs-MS link), respectively.
(FR)L'invention porte sur un procédé de sélection de relais et de communication coopératif qui fournit un critère de sélection de seuil pour former un groupe fiable de stations relais (RS) sur la base d'un ou de plusieurs critères de mise au point. Des critères de mise au point possibles comprennent une contrainte de probabilité d'interruption et une contrainte de débit. La valeur seuil est sélectionnée selon, par exemple, les trajets de transmission (par exemple, ligne de visée, ligné de visée obstruée, non-ligne de visée) ou des conditions de canal (par exemple, rapport signal sur bruit) entre la station de base (BS) et les RS (à savoir, liaison BS-RS) et entre les RS et la station mobile (MS) (à savoir, liaison RS-MS, respectivement.
