Title (EN) ROBUST TRANSMISSION ON DOWNLINK DISCONTINUOUS TRANSMISSION CARRIER
(FR) EMISSION ROBUSTE SUR UNE PORTEUSE D'ÉMISSION DISCONTINUE EN LIAISON DESCENDANTE
Abstract: front page image
(EN)A method and system for downlink discontinuous transmission are provided. In one embodiment, a base station includes a memory, a processor and a transmitter. The memory stores information to be transmitted in a subset of sub frames to a UE. The information includes transmission mode configuration information. The processor operates to configure the transmitter according to a selected transmission mode configuration that includes one of a transmit diversity mode and a MIMO mode, and configures the transmitter to transmit discontinuously and include CRS in only a subset of sub frames.
(FR)L'invention concerne un procédé et un système d'émission discontinue en liaison descendante. Dans un mode de réalisation, une station de base comprend une mémoire, un processeur et un émetteur. La mémoire conserve des informations à envoyer à un UE dans un sous-ensemble de sous-trames. Les informations comprennent des informations de configuration du mode d'émission. Le processeur a pour fonction de configurer l'émetteur selon une configuration choisie du mode d'émission qui comprend soit un mode de diversité en émission, soit un mode MIMO, et configure l'émetteur en vue d'émettre de manière discontinue et de n'inclure des CRS que dans un sous-ensemble de sous-trames.
