Abstract

La présente invention se rapporte au domaine technique des communications, et concerne un procédé de transmission répétée et un dispositif/un support de stockage/un appareil. Le procédé consiste à : en réponse à la commutation d'un dispositif de communication d'un premier faisceau à un second faisceau pour une transmission répétée, déterminer un premier nombre de répétitions de transmission répétée après la commutation. Selon la présente invention, en vue d'une commutation de faisceau dans un processus de transmission répétée, une approche pour déterminer un premier nombre de répétitions de transmission répétée après la commutation est fournie, et une transmission répétée stable après la commutation de faisceau est assurée.
