Abstract
(EN)
Techniques to support operation in a compressed mode and a continuous packet connectivity (CPC) mode are described. In an aspect, a user equipment (UE) may- obtain an assignment of enabled subframes for the CPC mode and an assignment of transmission gaps for the compressed mode. The transmission gaps may be aligned with idle times between the enabled subframes. The UE may exchange data during enabled subframes not overlapping the transmission gaps and may skip data exchanges during enabled subframes overlapping the transmission gaps. The UE may make cell measurements during the transmission gaps. In another aspect, the UE may obtain enabled subframes and skipped subframes, exchange data during enabled subframes not corresponding to the skipped subframes, and skip data exchanges during the skipped subframes. In yet another aspect, the UE may receive orders on a shared control channel to quickly enable and disable the compressed mode.

(FR)
L'invention concerne des techniques permettant de prendre en charge un fonctionnement en mode compressé et/ou un mode de connectivité en paquets continus (CPC). Selon un aspect, un équipement utilisateur (UE) peut obtenir une affectation de sous-trames validées pour le mode de connectivité CPC et une affectation d'intervalles de transmission pour le mode compressé. Les intervalles de transmission peuvent être alignés avec des durées à l'état inactif entre les sous-trames validées. L'équipement utilisateur peut échanger des données pendant des sous-trames validées ne chevauchant pas les intervalles de transmission et peut sauter des échanges de données pendant des sous-trames validées chevauchant les intervalles de transmission. L'équipement utilisateur peut effectuer des mesures de cellules pendant les intervalles de transmission. Selon un autre aspect, l'équipement utilisateur peut obtenir des sous-trames validées et des sous-trames sautées, échanger des données pendant des sous-trames validées ne correspondant pas aux sous-trames sautées et sauter des échanges de données pendant les sous-trames sautées. Selon encore un autre aspect, l'équipement utilisateur peut recevoir des instructions sur un canal de commande partagé afin de valider et d'invalider rapidement le mode compressé.
