Abstract
(EN)
Certain aspects of the present disclosure propose techniques for generating a channel quality indicator (CQI) with filtered interference in TD-HSDPA systems. Certain aspects provide a method that generally includes receiving a request for CQI information at a downlink time slot, calculating a signal-to-noise ratio (SNR) based on interference measurements recorded at one or more previous downlink time slots, and generating the CQI information based on the SNR.
(FR)
Certains aspects de la présente invention concernent des techniques servant à générer un indicateur de qualité de canal (CQI) avec interférences filtrées dans des systèmes TD-HSDPA. Certains aspects concernent un procédé qui consiste en général à : recevoir une demande d'informations de CQI dans un intervalle de temps de liaison descendante ; calculer un rapport signal sur bruit (SNR) en se basant sur des mesures d'interférences enregistrées dans un ou plusieurs intervalles de temps de liaison descendante précédents ; et générer les informations de CQI sur la base du signal SNR.
