Abstract
(EN) A method for determining a modulation and coding scheme. The method is executed in a network device. The method comprises: determining K, the number of terminal devices which multiplex a first time-frequency resource within a first time period and perform downlink data transmission with the network device, where K ≥ 2 (S210); acquiring a channel quality indication (CQI), wherein the CQI is determined according to a signal-to-noise ratio (SINR) of a channel and the number of terminal devices being K, the channel is a channel based on the first time-frequency resource, and the channel is used for transmitting downlink data between a first terminal device and the network device within the first time period (S220); and determining a modulation and coding scheme (MCS) of the first terminal device according to the CQI (S230).
(FR) L'invention concerne un procédé pour déterminer une technique de modulation et de codage. Le procédé est exécuté dans un dispositif de réseau. Le procédé consiste : à déterminer K, le nombre de dispositifs de terminal qui effectuent un multiplexage d'une première ressource temps-fréquence dans une première période de temps et réalisent une transmission de données de liaison descendante avec le dispositif de réseau, où K ≥ 2 (S210); à acquérir une indication de qualité de canal (CQI), la CQI étant déterminée selon un rapport signal sur bruit (SINR) d'un canal et le nombre de dispositifs de terminal étant K, le canal étant un canal basé sur la première ressource temps-fréquence, et le canal étant utilisé pour transmettre des données de liaison descendante entre un premier dispositif de terminal et le dispositif de réseau dans la première période de temps (S220); et à déterminer une technique de modulation et de codage (MCS) du premier dispositif de terminal selon la CQI (S230).
