Le procédé d'envoi/réception de PSCCH et l'appareil associé peuvent être appliqués dans des systèmes de communication et le procédé comprend les étapes suivantes : lorsqu'un dispositif terminal effectue un envoi en liaison latérale (SL), déterminer un premier ensemble de blocs de ressources physiques (PRB) dans un premier ensemble de blocs de ressources entrelacées (IRB) occupé par un PSCCH et envoyer le PSCCH au moyen du premier ensemble de PRB, le premier ensemble d'IRB comprenant un ou plusieurs premiers IRB et le premier ensemble de PRB comprenant un ou plusieurs premiers PRB ; et lorsque le dispositif terminal effectue une réception SL, déterminer le premier PRB dans le premier IRB occupé par le PSCCH et effectuer une détection à l'aveugle sur le PSCCH au niveau de la position du premier PRB. Dans les modes de réalisation de la présente demande, lorsqu'une communication en liaison latérale est effectuée au moyen de l'utilisation d'un spectre partagé, la position de domaine fréquentiel du PSCCH peut être déterminée avec précision.
