HALF-DUPLEX OPERATION IN NEW RADIO SYSTEMS
(FR)
FONCTIONNEMENT EN SEMI-DUPLEX DANS DES SYSTÈMES NOUVELLE RADIO
Abstract:
(EN)
Methods, systems, and devices for wireless communication are described. A base station may communicate with a user equipment (UE) using frequency resources (
e.g.,
subcarriers) with scalable channel spacing and time resources (
e.g.,
slots) with variable slot durations. The individual slots may include multiple symbols, and each symbol may be allocated for communication in a specific link direction (
e.g.,
uplink, downlink, or sidelink). For UEs configured to operate in a half-duplex mode, the base station may allocate sufficient time for the UE to transition between uplink and downlink configurations. In other cases, for carrier aggregation, the base station may coordinate with the UE to prevent conflicting communications (
e.g.,
simultaneous uplink and downlink transmissions). UEs or other devices may communicate directly with one another in a device-to-device configuration using the same or a similar scheme to allow for half-duplex devices to transition between sending and receiving.
(FR)
L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. Une station de base peut communiquer avec un équipement utilisateur (UE) en utilisant des ressources de fréquence (
par exemple
des sous-porteuses), des ressources de temps et d'espacement de canaux évolutives (
par exemple
des créneaux) ayant des durées de créneaux variables. Les créneaux individuels peuvent contenir de multiples symboles. Chaque symbole peut être attribué en vue d'une communication dans une direction de liaison spécifique (
par exemple
une liaison montante, une liaison descendante ou une liaison latérale). Pour des UE configurés de façon à fonctionner en un mode de semi-duplex, la station de base peut attribuer un temps suffisant pour que l'UE bascule entre des configurations de liaison montante et de liaison descendante. Dans d'autres cas, pour une agrégation de porteuses, la station de base peut se coordonner avec l'UE de façon à empêcher des communications conflictuelles (
par exemple
des transmissions simultanées en liaison montante et en liaison descendante). Des UE ou d'autres dispositifs peuvent communiquer directement entre eux dans une configuration de dispositif à dispositif en utilisant le même schéma ou un schéma similaire pour permettre à des dispositifs en semi-duplex de basculer entre envoi et réception.
