Abstract

Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un premier équipement utilisateur (UE) peut utiliser une coopération d'UE pour distribuer, entre le premier UE et un second UE, des communications entre le premier UE et une station de base. L'UE peut recevoir, en provenance du second UE, des données de radiomessagerie indiquant au moins une occasion de surveillance de radiomessagerie associée au second UE. L'UE peut poursuivre ou mettre fin de manière sélective, sur la base, au moins en partie, des données de radiomessagerie, à la coopération d'UE pour des communications ultérieures entre le premier UE et la station de base. De nombreux autres aspects sont décrits.
