Abstract

La présente invention concerne des procédés et des appareils de communication sans fil. Un procédé de communication sans fil comprend : un premier dispositif terminal effectuant une opération de gestion de mobilité sur la base d'une première condition et/ou d'une deuxième condition, la première condition étant une condition de mesure de position, la deuxième condition étant une condition de mesure de signal, et la première condition et la deuxième condition étant associées à une capacité de traitement d'antenne du premier dispositif terminal. Dans la présente invention, un premier dispositif terminal peut effectuer une opération de gestion de mobilité au moyen d'une condition associée à une capacité de traitement d'antenne de celui-ci. Étant donné qu'une condition utilisée par un dispositif terminal est associée à une capacité de traitement d'antenne du dispositif terminal, dans les modes de réalisation de la présente invention, la différence entre les capacités de traitement d'antenne de dispositifs terminaux peut être complètement prise en compte, de sorte qu'un dispositif terminal peut exécuter plus précisément une décision associée concernant une opération de gestion de mobilité selon sa propre capacité de traitement d'antenne.
