Title (EN) A FIRST NETWORK NODE, A SECOND NETWORK NODE, AND METHODS THEREIN FOR HANDOVER
(FR) PREMIER NŒUD DE RÉSEAU, SECOND NŒUD DE RÉSEAU, ET PROCÉDÉS ASSOCIÉS DE TRANSFERT INTERCELLULAIRE
Abstract:
(EN) A first Network Node (NN) (206) and a method therein for enabling handover of a first and a second wireless device (210, 212) from the first NN to a second NN (208). The first NN determines that the second wireless device is to refrain from transmitting an uplink synchronization signal. Based on the determination, the first NN configures the first wireless device to transmit an uplink synchronization signal and to synchronize to a first downlink synchronization signal, an configures the second wireless device to synchronize to a second downlink synchronization signal. The first NN receives, from the second NN, information relating to a measurement performed on the uplink synchronization signal transmitted only from the first wireless device. Based on the received information, the first NN requests the second NN to perform the handover of the first and second wireless devices.
(FR) L'invention concerne un premier nœud de réseau (NN) (206) et un procédé associé pour permettre un transfert intercellulaire d'un premier et d'un second dispositif sans fil (210, 212) du premier NN à un second NN (208). Le premier NN détermine que le second dispositif sans fil doit s'abstenir de transmettre un signal de synchronisation de liaison montante. Sur la base de la détermination, le premier NN configure le premier dispositif sans fil pour transmettre un signal de synchronisation de liaison montante et pour se synchroniser avec un premier signal de synchronisation de liaison descendante, et configure le second dispositif sans fil pour se synchroniser avec un second signal de synchronisation de liaison descendante. Le premier NN reçoit, en provenance du second NN, des informations relatives à une mesure effectuée sur le signal de synchronisation de liaison montante transmis uniquement à partir du premier dispositif sans fil. Sur la base des informations reçues, le premier NN demande au second NN d'effectuer le transfert intercellulaire des premier et second dispositifs sans fil.
