Title
(EN) METHOD FOR ENABLING DEVICE TO DEVICE COMMUNICATION IN A RADIO COMMUNICATIONS NETWORK
(FR) PROCÉDÉ POUR PERMETTRE DES COMMUNICATIONS DISPOSITIF À DISPOSITIF DANS UN RÉSEAU DE RADIOCOMMUNICATION
Abstract
(EN)
Embodiments herein relate to e.g. methods performed in first and second communication devices(10, 13) for enabling device to device communication between the first communication device (10) and the second communication device (13) in a radio communications network (1). The first communication device (10) transmits data in a first data transmission to the second communication device (13) according to a first transmission pattern. The first communication device (10) also transmits control information with the data to the second communication device (13),which control information indicates a second transmission pattern for a next data transmission from the first communication device (10) to the second communication device (13).The second communication device (13) receives the control information with the data in the first transmission. Further embodiments relate to the first and second communication devices (10, 13).

Des modes de réalisation de l'invention concernent des procédés exécutés dans des premier et second dispositifs de communication (10, 13) pour permettre une communication de dispositif à dispositif entre le premier dispositif de communication (10) et le second dispositif de communication (13) dans un réseau de radiocommunication (1). Le premier dispositif de communication (10) transmet des données, dans une première transmission de données au second dispositif de communication (13), selon un premier motif de transmission. Le premier dispositif de communication (10) transmet également des informations de commande, avec les données, au second dispositif de communication (13). Les informations de commande indiquent un second motif de transmission pour une autre transmission de données, du premier dispositif de communication (10) au second dispositif de communication (13). Le second dispositif de communication (13) reçoit les informations de commande, avec les données, dans la première transmission. D'autres modes de réalisation concernent les premier et second dispositifs de communication (10, 13).
