Title
(EN) TRANSMISSION PARAMETER ASSIGNMENT FOR MU-MIMO WIRELESS DEVICES
(FR) ATTRIBUTION DE PARAMÈTRES DE TRANSMISSION POUR DISPOSITIFS SANS FIL MU-MIMO
Abstract
(EN)
A network node assigns a transmission parameter, e.g., an Antenna Port Identifier (APID) and a Scrambling Code Identifier (SCID) combination, to each of a plurality of wireless devices responsive to the channel correlations between each pair of wireless devices formed from the plurality of wireless devices, to facilitate the transmission of data from the network node to each wireless device. Such intelligent transmission parameter assignment reduces interference and/or improves throughput.
(FR)
L'invention concerne un nœud de réseau qui attribue un paramètre de transmission, par exemple, une combinaison d'un identifiant de port d'antenne (APID) et d'un identifiant de code de brouillage (SCID), à chacun d'une pluralité de dispositifs sans fil en réponse aux corrélations de canaux entre chaque paire de dispositifs sans fil formée à partir de la pluralité de dispositifs sans fil, pour faciliter la transmission de données du nœud de réseau à chaque dispositif sans fil. Une telle attribution intelligente de paramètres de transmission réduit les interférences et/ou améliore le débit.
