Title
(EN) METHOD AND APPARATUS FOR OPERATING SUPPLEMENTARY CELLS IN LICENSED EXEMPT SPECTRUM
(FR) PROCÉDÉ ET APPAREIL POUR FAIRE FONCTIONNER DES CELLULES SUPPLÉMENTAIRES DANS UN SPECTRE EXEMPT DE LICENCE
Abstract
(EN)
A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

L'invention concerne un procédé et un appareil pour faire fonctionner des cellules supplémentaires dans un spectre exempt de licence (LE). Une cellule d'agrégation fonctionnant dans un spectre licencié en duplexage par répartition en fréquence (FDD) est agrégée avec une cellule supplémentaire LE fonctionnant en mode de partage temporel pour des opérations de liaison montante (UL) et de liaison descendante (DL). La cellule supplémentaire (LE) peut être une cellule supplémentaire FDD qui peut être dynamiquement configurée entre un mode UL seulement, un mode DL seulement, et un mode commun, pour s'adapter aux rapports de traffic UL et DL voulus. La cellule supplémentaire LE peut être une cellule supplémentaire à duplexage par répartition dans le temps (TDD). La cellule supplémentaire TDD peut être dynamiquement configurée entre plusieurs configurations TDD. Des opérations de coordination entre la cellule supplémentaire LE et d'autres systèmes fonctionnant dans la même voie peuvent coexister. Des espaces de coexistence permettent de mesurer une utilisation d'utilisateur primaire/secondaire et permet à d'autres systèmes qui fonctionnent dans la voie de la cellule supplémentaire LE d'accéder à ladite voie.
