Abstract
(EN) A method of retransmission a data packet in a wireless communication system between a base station having multiple antennas and a mobile station is disclosed. The mobile station determines a retransmission format (S30) from a plurality of retransmission formats and informs the base station about the determined retransmission format (S40) by which to retransmit the data packet. The retransmission format is different from an initial transmission format.
(FR) La présente invention concerne un procédez de retransmission de paquets de données dans un système de communication sans fil possédant des antennes multiples. Plus spécifiquement, une station mobile (MS) détermine le format de retransmission à partir d'une pluralité de formats de retransmission puis informe du format de retransmission déterminé par lequel le paquet de données pourra être retransmis.
