Title
(EN) ENHANCED USE OF FREQUENCY SPECTRUM IN A WIRELESS COMMUNICATION NETWORK
(FR) UTILISATION AMÉLIORÉE DU SPECTRE DE FRÉQUENCE DANS UN RÉSEAU DE COMMUNICATION SANS FIL
Abstract
(EN)
The present invention relates to a user terminal (1) arranged for communication with at least one node (2) in a wireless communication network (3). The user terminal (1) is arranged to measure received signal characteristics from at least one other user terminal (4, 5) when it is transmitting signals (6, 7; 8, 9). The measured received signal characteristics are comprised in measurement data. The user terminal (1) is arranged to transfer the measurement data to said node (2) at certain times. The present invention also relates to a node (2) that is arranged to schedule transmission and reception of signals such that each user terminal (1, 4, 5) that communicates via the node (2) either transmits or receives signals to/from the node (2) at a first frequency interval. The node (2) is arranged to transmit and receive signals simultaneously at the first frequency interval. The present invention also relates to a method.
(FR)
La présente invention porte sur un terminal utilisateur (1) conçu pour communiquer avec au moins un nœud (2) dans un réseau de communication sans fil (3). Le terminal utilisateur (1) est conçu pour mesurer des caractéristiques de signaux reçus en provenance d'au moins un autre terminal utilisateur (4, 5) lorsqu'il est en train d'émettre de signaux (6, 7; 8, 9). Les caractéristiques de signaux reçus mesurées sont comprises dans des données de mesure. Le terminal utilisateur (1) est conçu pour transférer les données de mesure audit nœud (2) à certains moments. La présente invention porte également sur un nœud (2) qui est conçu pour planifier l'émission et la réception de signaux de manière à ce que chaque terminal utilisateur (1, 4, 5) qui communique par l'intermédiaire du nœud (2) émette ou reçoive des signaux à destination/en provenance du nœud (2) au niveau d'un premier intervalle de fréquence. Le nœud (2) est conçu pour émettre et recevoir des signaux simultanément au niveau du premier intervalle de fréquence. La présente invention porte également sur un procédé.
