Title (EN) PROVIDING WIRELESS TERMINAL UPLINK DATA RATE OFFSETS
(FR) FOURNITURE DE DÉCALAGES DE DÉBIT DE DONNÉES DE LIAISON MONTANTE DE TERMINAL SANS FIL
Abstract: front page image
(EN)Methods to provide power control during a soft handover are provided, traditionally, power control is done by setting a target Signal to Interference (and noise) Ratio, SIR/SINR, target or a power target. Herein, and as in 3GPP contribution R1-131608, a rate adaptation method is used instead. The problem occurring during soft handover is that the non-serving cell may decode the UE transmissions better than the serving cell, but the serving cell, without this knowledge, may instead reduce the rate, hence reducing the gain of soft handover. It is therefore proposed to, at the RNC (which knows the HARQ retransmission performance from all cells in the active set) generate an uplink data rate offset value responsive to a retransmission indication, transmitting the uplink data rate offset value to the serving base station for transmission to the wireless terminal. Alternatively to the explicit uplink data rate offset, the RNC does not need to be aware that the UE is operating in rate adaptation mode, thus setting a target SIR or power as conventionally. It is the NodeB that interprets the SIR target changes as rate change commands.
(FR)L'invention concerne des procédés permettant d'assurer des communications sans fil dans un transfert intercellulaire sans coupure. Un procédé permettant d'assurer des communications sans fil dans un transfert intercellulaire sans coupure peut inclure la réception, lorsque le terminal sans fil est dans le transfert intercellulaire sans coupure par rapport à une station de base de desserte et une station de basse de non-desserte, une indication de retransmission par l'intermédiaire de la station de base de desserte ou la station de basse de non-desserte. Le procédé peut inclure la génération d'une valeur de décalage de débit de données en réponse à l'indication de retransmission. De surcroît, le procédé peut inclure la transmission de la valeur de décalage de débit de liaison montante à la station de base de desserte pour transmission au terminal sans fil. L'invention concerne également des nœuds et des terminaux sans fil apparentés.
