Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a method and device for information detection and information transmission.

SOLUTION: A method for information detection and information transmission includes: a step in which UE acquires at least one type of arrangement information on an antenna port occupied by a D-PDCCH the at least one type of arrangement information being set on the base station side; a step in which the UE determines a search area for the D-PDCCH; and a step in which the UE detects the D-PDCCH in the search area according to the arrangement information on the antenna port.

EFFECT: UE can detect a D-PDCCH data transmission is therefore ensured. Further blind detection for a PDCCH by the UE based on time/frequency resources in an existing system is extended in a spatial dimension or an antenna port. Thereby resource utilization efficiency is improved which makes it possible to detect the D-PDCCH in the spatial dimension.
