Abstract[English]
Methods and systems for enabling terminal devices to perform a physical random access channel (PRACH) transmission for non-serving cells are provided. In some embodiments, the method includes (1) receiving, by a terminal device, configuration information of PRACH of one or more non-serving cells; (2) receiving, by the terminal device, a control signaling; (3) determining, by the terminal device, a PRACH preamble and a PRACH occasion according to the configuration information; and (4) transmitting, by the terminal device the PRACH preamble in the PRACH occasion. The control signaling indicates the terminal device to transmit PRACH information to a first non-serving cell of the one or more non-serving cells.[French]
L'invention concerne des procédés et des systèmes destinés à permettre à des dispositifs terminaux d'effectuer une transmission de canal physique d'accès aléatoire (PRACH) pour des cellules hors desserte. Dans certains modes de réalisation, le procédé comprend (1) la réception, par un dispositif terminal, d'informations de configuration de PRACH d'une ou de plusieurs cellules hors desserte ; (2) la réception, par le dispositif terminal, d'une signalisation de commande ; (3) la détermination, par le dispositif terminal, d'un préambule de PRACH et d'une occasion de PRACH selon les informations de configuration ; et (4) la transmission, par le dispositif terminal, du préambule de PRACH dans l'occasion de PRACH. La signalisation de commande indique au dispositif terminal de transmettre des informations de PRACH à une première cellule hors desserte de la ou des cellules hors desserte.
