Detection, apparatus and method for transmitting information

Embodiment of the present invention discloses a detecting method and apparatus for transmitting information, the method comprising:?? D UE to obtain a base station side arranged at least one antenna port configuration information occupied by the PDCCH; the UE determines the PDCCH D search space; the UE according to the antenna port configuration information, detected in the search space D PDCCH?. Application of an embodiment of the present invention, so that the UE can detect the D? PDCCH, thereby ensuring the data transmission. Furthermore, the conventional PDCCH blind detection when the UE based on system frequency resource is extended to a spatial dimension, i.e. the antenna port, improving the utilization efficiency of resources, so that the space can be detected dimension D? PDCCH.
