Title
(EN) TRANSMITTING REFERENCE SIGNALS FOR DEVICE-TO-DEVICE COMMUNICATIONS
(FR) SIGNAUX DE REFERENCE DE TRANSMISSION POUR COMMUNICATIONS DE DISPOSITIF À DISPOSITIF
Abstract
(EN)
The present disclosure describes wireless communication devices and methods performed by such wireless devices for providing reference signals for device-to-device communication. An exemplary method includes determining, for a first transmission, an allocation of physical resources according to a subframe format that positions one or more reference signals for channel state information at the transmitter (CSIT) in a symbol position that avoids overlap with a data symbol in a concurrent second transmission and transmitting the first transmission having the allocation of physical resources accord to the determined subframe format.
(FR)
La présente invention concerne des dispositifs de communication sans fil et des procédés mis en oeuvre par de tels dispositifs sans fil pour générer des signaux de référence pour une communication de dispositif à dispositif. Un procédé donné à titre d'exemple consiste à déterminer, pour une première transmission, une attribution de ressources physiques selon un format de sous-trame qui positionne un ou plusieurs signaux de référence pour des informations d'état de canal au niveau de l'émetteur (CSIT) dans une position de symbole qui évite un chevauchement avec un symbole de données dans une seconde transmission simultanée, et à effectuer la première transmission comportant l'attribution de ressources physiques selon le format de sous-trame déterminé.
