Abstract

Des modes de réalisation de la présente demande concernent un procédé d'affichage d'instruction et un produit associé. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des premières informations envoyées par un dispositif de réseau, les premières informations étant utilisées pour ordonner au dispositif terminal de transmettre à un seul TRP ou ordonner au dispositif terminal de transmettre à une pluralité de RP, de telle sorte que le dispositif terminal peut déterminer, selon les premières informations, s'il faut ou non transmettre à un seul TRP ou à une pluralité de RP. Par conséquent, une solution technique qui prend en charge la commutation dynamique d'un dispositif terminal entre une transmission à un seul TRP et une transmission à une pluralité de RP est fournie.
