Title
(EN) IMPROVED RANDOM ACCESS PROCEDURE AND UPLINK-BASED MOBILITY
(FR) PROCÉDURE D'ACCÈS ALÉATOIRE ET MOBILITÉ BASÉE SUR UNE LIAISON MONTANTE AMÉLIORÉES
Abstract
(EN) Wireless communications systems and methods related to random access and uplink (UL)-based mobility are provided. A first wireless communication device transmits a first signal carrying a random access sequence and a data. The first wireless communication device receives a second signal from a second wireless communication device in response to the first signal. For random access, the data in the first signal includes at least one of an identifier of the first wireless communication device or a connection request, and the second signal includes at least one of timing advance information or a contention resolution. For UL-based mobility, the data in the first signal includes at least an identifier of the first wireless communication device, and the second signal includes at least an acknowledgement for the first signal or paging information associated with the first wireless communication device.
(FR) L'invention concerne des systèmes et des procédés de communication sans fil associés à un accès aléatoire et à une mobilité basée sur une liaison montante (UL). Un premier dispositif de communication sans fil émet un premier signal véhiculant une séquence d'accès aléatoire et des données. En réponse au premier signal, le premier dispositif de communication sans fil reçoit un second signal provenant d'un second dispositif de communication sans fil. Pour un accès aléatoire, les données dans le premier signal contiennent un identifiant du premier dispositif de communication sans fil et/ou une demande de connexion et le second signal contient des informations d'avance temporelle et/ou une résolution de conflit. Pour une mobilité basée sur une UL, les données dans le premier signal contiennent au moins un identifiant du premier dispositif de communication sans fil et le second signal contient au moins un accusé de réception pour le premier signal ou des informations de recherche associées au premier dispositif de communication sans fil.
