Title
(EN) METHODS, TERMINAL DEVICE AND BASE STATION FOR CHANNEL SENSING IN UNLICENSED SPECTRUM
(FR) PROCÉDÉS, DISPOSITIF TERMINAL ET STATION DE BASE DESTINÉS À LA DÉTECTION DE CANAL DANS UN SPECTRE SANS LICENCE
Abstract
(EN)
Methods, a terminal device and a base station are disclosed for channel sensing in unlicensed spectrum. According to an embodiment, a terminal device determines to perform physical random access channel (PRACH) or physical uplink control channel (PUCCH) transmission in unlicensed spectrum. The base station determines one or more listen before talk (LBT) parameters for the PRACH or PUCCH transmission according to a purpose of the PRACH or PUCCH transmission.

L'invention concerne des procédés, un dispositif terminal et une station de base destinées à la détection de canal dans un spectre sans licence. Selon un mode de réalisation, un dispositif terminal détermine d'effectuer une transmission par canal physique à accès aléatoire (PRACH) ou par canal physique à commande de liaison montante (PUCCH) dans un spectre sans licence. La station de base détermine au moins un paramètre d'accès multiple avec écoute de porteuse (LBT) correspondant à la transmission par PRACH ou par PUCCH, selon un but de la transmission par PRACH ou par PUCCH.
