Title (EN) QCL (QUASI CO-LOCATION) FOR DM-RS (DEMODULATION REFERENCE SIGNAL) ANTENNA PORTS FOR COMP (COORDINATED MULTI-POINT)
(FR) QCL (QUASI CO-LOCALISATION) POUR DES PORTS D'ANTENNE DM-RS (SIGNAL DE RÉFÉRENCE DE DÉMODULATION) DE COMP (MULTIPOINT COORDONNÉ)
Abstract:
(EN) Techniques for determining whether DM-RS (Demodulation Reference Signal) APs (Antenna Ports) are QCL-ed (Quasi Co-Located) with co-scheduled DM-RS APs are discussed. One example embodiment can comprise an apparatus that can be employed at a UE (User Equipment), that can comprise a memory; and one or more processors configured to: process higher layer signaling that indicates, in connection with a MU (Multi User)-MIMO (Multiple Input Multiple Output) transmission, a QCL (Quasi Co-Location) type for one or more DM-RS (Demodulation Reference Signal) APs (Antenna Ports) associated with the UE; and determine, based on the indicated QCL type, whether the one or more DM-RS APs are QCL-ed (Quasi Co-Located) with one or more co-scheduled DM-RS APs associated with a distinct UE.
(FR) L'invention concerne des techniques permettant de déterminer si des AP (ports d'antenne) de DM-RS (signal de référence de démodulation) sont QCL-ed (quasi co-localisés) avec des AP DM-RS co-programmés. Un mode de réalisation donné à titre d'exemple peut comprendre un appareil pouvant être utilisé au niveau d'un équipement utilisateur (UE), qui peut comprendre une mémoire; et un ou plusieurs processeurs configurés pour : un traitement de couche supérieure de processus indiquant, en connexion avec une transmission MU (multiutilisateurs)-MIMO (entrées multiples sorties multiples), un type de QCL (quasi localisation) pour un ou plusieurs AP (ports d'antenne) d DM-RS (signal de référence de démodulation) associés à l'UE; et déterminer, sur la base du type de QCL indiqué, si lesdits AP DM-RS sont QCL-ed (quasi co-localisés) avec un ou plusieurs AP DM-RS co-programmés associés à un UE distinct.
