Étant donné que la première ressource de transmission est associée aux autres ressources de transmission, pour chaque groupe de ressources de transmission, seules les premières informations d'indication sur la première ressource de transmission doivent être détectées afin de déterminer clairement, sur la base des premières informations d'indication, le comportement de transmission sur les autres ressources de transmission ultérieures. Ainsi, la complexité de détection aveugle pour un groupe de ressources de transmission peut être réduite, ce qui permet d'obtenir les effets d'économie d'énergie et de réduction de consommation.
