Title
(EN) GRANT-FREE UPLINK TRANSMISSION IN UNLICENSED SPECTRUM
(FR) TRANSMISSION EN LIAISON MONTANTE SANS AUTORISATION DANS UN SPECTRE SANS LICENCE
Abstract
(EN)
Methods and devices for grant-free uplink transmission in unlicensed spectrum are provided. A base station (BS) transmits grant-free resource configuration information to one or more electronic devices (EDs). The grant-free resource configuration information is used to configure the ED for GF uplink transmission in unlicensed spectrum. The GF resource configuration information includes GF ED group-specific resource configuration information indicating GF ED group-specific time-frequency (T/F) resources of the unlicensed spectrum for GF uplink transmission. The ED (s) transmit grant-free uplink transmissions over the unlicensed spectrum in accordance with the GF resource configuration information.

La présente invention concerne des procédés et des dispositifs de transmission en liaison montante sans autorisation (GF) dans un spectre sans licence. Une station de base (BS) transmet des informations de configuration de ressources sans autorisation à un ou à plusieurs dispositifs électroniques (ED). Les informations de configuration de ressources sans autorisation sont utilisées pour configurer les ED en vue d'une transmission en liaison montante GF dans un spectre sans licence. Les informations de configuration de ressources GF comprennent des informations de configuration de ressources GF spécifiques à un groupe d'ED, indiquant des ressources temps-fréquence (T/F) GF spécifiques à un groupe d'ED du spectre sans licence en vue d'une transmission en liaison montante GF. Lesdits ED transmettent des transmissions en liaison montante GF sur le spectre sans licence conformément aux informations de configuration de ressources GF.
