Title
(EN) METHOD AND APPARATUS FOR SCHEDULING USER EQUIPMENT UPLINK TRANSMISSIONS ON AN UNLICENSED CARRIER

Abstract
(EN)
A method and apparatus schedule user equipment uplink transmissions on an unlicensed carrier. A configuration indicating a window length can be received from a higher layer, where the higher layer can be higher than a physical layer. A grant can be received in a subframe, where the grant can be for transmitting a physical uplink shared channel on a serving cell operating on an unlicensed carrier. A set of subframes for possible transmission of the physical uplink shared channel can be determined based on the window length and the subframe in which the grant is received. Listen before talk can be performed on the unlicensed carrier to determine an earliest unoccupied subframe in the set of subframes. The physical uplink shared channel can be transmitted in the earliest unoccupied subframe in response to receiving the grant.

L'invention concerne un procédé et un appareil qui planifient des transmissions en liaison montante d'équipement utilisateur sur une porteuse non autorisée. Une configuration indiquant une longueur de fenêtre peut être reçue à partir d'une couche supérieure, la couche supérieure pouvant être plus haute qu'une couche physique. Une autorisation peut être reçue dans une sous-trame, l'autorisation pouvant être destinée à transmettre un canal partagé de liaison montante physique sur une cellule de desserte fonctionnant sur une porteuse non autorisée. Un ensemble de sous-trames permettant la transmission éventuelle du canal partagé de liaison montante physique peut être déterminé sur la base de la longueur de fenêtre et de la sous-trame dans laquelle l'autorisation est reçue. La fonction écouter avant de parler peut être réalisée sur la porteuse non autorisée pour déterminer une première sous-trame non occupée dans l'ensemble de sous-trames. Le canal partagé de liaison montante physique peut être transmis dans la première sous-trame non occupée en réponse à la réception de l'autorisation.
