Abstract
(EN) A user equipment (UE) is described. The UE includes reception circuitry configured to receive downlink control information (DCI) indicating aperiodic sounding reference signal (SRS) transmission without an uplink shared channel (UL-SCH) and without a channel state information (CSI) request. The UE also includes transmission circuitry configured to transmit sounding reference signals. A cyclic redundancy check (CRC) bit for a first DCI indicating aperiodic SRS transmission for scheduling UL-SCH and/or triggering a CSI report is scrambled by a first radio network temporary identifier (RNTI). A CRC bit for the first DCI indicating aperiodic SRS transmission without an UL-SCH and without a CSI request is scrambled by a second RNTI.
(FR) L'invention concerne un équipement utilisateur (UE). L'UE comprend un montage de circuits de réception configuré pour recevoir des informations de commande de liaison descendante (DCI) indiquant une transmission de signal de référence de sondage (SRS) apériodique sans canal partagé de liaison montante (UL-SCH) et sans demande d'Informations d'état de canal (CSI). L'UE comprend également un montage de circuits de transmission configuré pour émettre des signaux de référence de sondage. Un bit de contrôle de redondance cyclique (CRC) pour un premier élément de DCI indiquant une transmission de SRS apériodique pour programmer un UL-SCH et/ou déclencher un rapport de CSI est embrouillé par un premier identifiant temporaire de réseau radio (RNTI). Un bit de CRC pour le premier élément de DCI indiquant une transmission de SRS apériodique sans UL-SCH et sans demande de CSI est embrouillé par un second RNTI.
