CA 2675086

Techniques for performing power control during discontinuous transmission (DTX) operation are described. A UE transmits on the uplink during a transmission burst and receives TPC commands generated by a Node B based on the uplink transmission. The UE may receive two TPC commands at the end of the transmission burst that are not applied during the transmission burst. The UE saves and applies these two TPC commands in the next transmission burst. In one design, the UE applies each saved TPC command in one slot of the next transmission burst. In another design, the UE combines the two saved TPC commands and applies the combined value in the first two slots of the next transmission burst. In yet another design, the UE selects one of the saved TPC commands and applies the selected TPC command in the first two slots of the next transmission burst.

L'invention concerne des techniques pour effectuer une commande de puissance pendant une opération de transmission discontinue (DTX). Un UE transmet sur la liaison montante pendant une rafale de transmission et reçoit des ordres TPC générés par un nAEud B basé sur la transmission de liaison montante. L'UE peut recevoir deux ordres TPC à la fin de la rafale de transmission qui ne sont pas appliqués pendant la rafale de transmission. L'UE enregistre et applique ces deux ordres TPC dans la rafale de transmission suivante. Dans une conception, l'UE applique chaque ordre TPC enregistré dans un intervalle de la rafale de transmission suivante. Dans une autre conception, l'UE combine les deux ordres TPC enregistrés et applique la valeur combinée dans les deux premiers intervalles de la rafale de transmission suivante. Dans une autre conception, l'UE sélectionne l'un des ordres TPC enregistrés et applique l'ordre TPC sélectionné dans les deux premiers intervalles de la rafale de transmission suivante.
