(EN) BEAM RECOVERY PROCEDURE FOR FULL DUPLEX OPERATION
(FR) PROCÉDURE DE RÉCUPÉRATION DE FAISCEAU POUR FONCTIONNEMENT EN DUPLEX INTÉGRAL
Abstract
(EN)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit an indication to a base station to configure a control channel of a downlink beam in accordance with a full duplex failure detection control resource set (CORESET), wherein the full duplex failure detection CORESET is used based at least in part on the UE being associated with a full duplex communication link that includes the downlink beam and an uplink beam; and monitor a reference signal on the control channel of the downlink beam based at least in part on the full duplex failure detection CORESET in order to detect a beam failure on the downlink beam while transmitting the uplink beam, wherein monitoring the reference signal is based at least in part on a threshold that is based on one or more uplink transmission parameters. Numerous other aspects are provided.

La présente invention se rapporte d'une manière générale, selon divers aspects, à la communication sans fil. Selon certains aspects, un équipement utilisateur peut transmettre à une station de base une indication de configurer un canal de commande d'un faisceau de liaison descendante conformément à un ensemble de ressources de commande (CORESET) de détection de défaillance en duplex intégral, le CORESET de détection de défaillance en duplex intégral étant utilisé sur la base, au moins en partie, de l'UE qui est associé à une liaison de communication en duplex intégral qui comprend le faisceau de liaison descendante et un faisceau de liaison montante ; et pour surveiller un signal de référence sur le canal de commande du faisceau de liaison descendante sur la base, au moins en partie, du CORESET de détection de défaillance en duplex intégral afin de détecter une défaillance de faisceau sur le faisceau de liaison descendante tout en transmettant le faisceau de liaison montante, la surveillance du signal de référence étant basée au moins en partie sur un seuil qui est basé sur un ou plusieurs paramètres de transmission de liaison montante. L'invention se présente également sous de nombreux autres aspects.
