Abstract[English]
Embodiments of the present disclosure relate to methods and apparatus for timing advance (TA) in a radio access network, in particular, through random access preamble transmission for TA maintenance. A terminal device receives, from a network device, a transmission mode configuration which indicates to the terminal device a transmission mode of a random access preamble. The transmission mode comprises a periodical mode or a one-shot mode. The terminal device transmits, to a target network device, the random access preamble based on the transmission mode. In this way, the terminal device can transmit the random access preamble based on the indicated transmission mode, thereby avoiding unnecessary transmissions of the random access preamble for TA maintenance.[French]
Des modes de réalisation de la présente divulgation concernent des procédés et un appareil d'avance temporelle (TA) dans un réseau d'accès radio, en particulier, par l'intermédiaire d'une transmission de préambule d'accès aléatoire pour une maintenance de TA. Un dispositif terminal reçoit, en provenance d'un dispositif de réseau, une configuration de mode de transmission qui indique au dispositif terminal un mode de transmission d'un préambule d'accès aléatoire. Le mode de transmission comprend un mode périodique ou un mode ponctuel. Le dispositif terminal transmet, à un dispositif de réseau cible, le préambule d'accès aléatoire sur la base du mode de transmission. De cette manière, le dispositif terminal peut transmettre le préambule d'accès aléatoire sur la base du mode de transmission indiqué, ce qui permet d'éviter des transmissions inutiles du préambule d'accès aléatoire pour une maintenance de TA.
