Title (EN) UPLINK SCHEDULING FOR LICENSE ASSISTED ACCESS
(FR) PLANIFICATION DE LIAISON MONTANTE POUR UN ACCÈS ASSISTÉ PAR LICENCE
Abstract:
(EN) Uplink scheduling for license assisted access (LAA) mode systems is discussed in which a base station transmits a conditional grant to served user equipments (UEs) that include a transmission configuration for uplink transmissions. The transmission configuration includes the parameters necessary for the UE to perform transmissions. Before the beginning of a uplink transmission opportunity, a base station transmits an uplink activation grant over a contention-based shared carrier to the served UEs. The uplink activation grant indicates the transmission opportunity to the UEs and may identify a subset of UEs out of the served UEs that are available for transmission. The base station first secures the channel before transmitting the uplink activation grant. Upon receipt of the uplink activation grant, the UEs determine whether they will perform uplink transmissions and, if so, transmit the uplink data according to the transmission configuration.
(FR) L'invention concerne une planification de liaison montante pour des systèmes à mode d'accès assisté par licence (LAA) dans laquelle une station de base transmet un accord conditionnel à des équipements utilisateurs (UE) desservis comprenant une configuration de transmission pour des transmissions en liaison montante. La configuration de transmission comprend les paramètres nécessaires pour permettre à l'UE d'effectuer des transmissions. Avant le début d'une opportunité de transmission en liaison montante, une station de base transmet une autorisation d'activation de liaison montante sur une porteuse partagée par contention aux UE desservis. L'autorisation d'activation de liaison montante indique l'opportunité de transmission aux UE et peut identifier un sous-ensemble d'UE parmi les UE desservis qui sont disponibles pour la transmission. La station de base sécurise d'abord le canal avant de transmettre l'autorisation d'activation de liaison montante. À la réception de l'autorisation d'activation de liaison montante, les UE déterminent s'ils vont effectuer des transmissions en liaison montante et, si tel est le cas, transmettent les données en liaison montante selon la configuration de transmission.
