Abstract
(EN)
Methods, systems, and devices for wireless communications are described that support techniques for intra-satellite handover. The described techniques provide for handovers such that a user equipment (UE) may transition from communications with a satellite via a first frequency (or set of frequencies) to communications with the same satellite via a second frequency (or set of frequencies). A UE may determine relevant timing and/or configuration for the second frequency (or set of frequencies) prior to transitioning from communications via the first frequency (or set of frequencies). Thus, the UE may efficiently begin communications at a second frequency (or set of frequencies) that are different than the first frequency (or set of frequencies)-for example, without performing a random access procedure.

La présente invention concerne des procédés, des systèmes et des dispositifs, pour des communications sans fil, qui prennent en charge des techniques pour un transfert intra-satellite. Les techniques selon l’invention permettent des transferts de sorte qu’un équipement d’utilisateur (UE) peut effectuer une transition pour passer de communications avec un satellite via une première fréquence (ou un premier ensemble de fréquences) à des communications avec le même satellite via une seconde fréquence (ou un second ensemble de fréquences). Un UE peut déterminer une synchronisation et/ou configuration pertinente pour la seconde fréquence (ou le second ensemble de fréquences) avant d’effectuer la transition depuis des communications via la première fréquence (ou le premier ensemble de fréquences). Ainsi, l’UE peut commencer efficacement des communications à une seconde fréquence (ou un second ensemble de fréquences) qui sont différentes d'avec la première fréquence (ou du premier ensemble de fréquences), par exemple, sans réaliser une procédure d’accès aléatoire.
