Abstract
(EN)
Aspects of the disclosure provide a user equipment (UE). The UE receives configuration information of multiple transmission configuration indication (TCI) states. The UE receives one or more activation commands that associate a first subset of the TCI states with one or more codepoints of a TCI field and a second subset of the TCI states with the one or more codepoints of the TCI field. The UE receives a codepoint associated with a first TCI state in the first subset of the TCI states and a second TCI state in the second subset of the TCI states. The UE determines at least one first quasi co-located (QCL) assumption according to the first TCI state and at least one second QCL assumption according to the second TCI state. The UE receives a downlink transmission based on the at least one first QCL assumption and the at least one second QCL assumption.

Selon certains aspects, l'invention concerne un équipement utilisateur (UE). L'UE reçoit des informations de configuration de plusieurs états d'indication de configuration de transmission (TCI). L'UE reçoit une ou plusieurs commandes d'activation qui associent un premier sous-ensemble des états TCI à un ou plusieurs points de code d'un champ TCI et un second sous-ensemble des états TCI avec le ou les points de code du champ TCI. L'UE reçoit un point de code associé à un premier état TCI dans le premier sous-ensemble des états TCI et un second état TCI dans le second sous-ensemble des états TCI. L'UE détermine au moins une première supposition de quasi co-localisation (QCL) en fonction du premier état TCI et au moins une seconde supposition QCL selon le second état TCI. L'UE reçoit une transmission de liaison descendante sur la base de la ou des premières suppositions de QCL et de la ou des secondes suppositions de QCL.
