Title:
Information detection and information transmission method, and information detection and information transmission device
Document Type and Number:
Japanese Patent JP6286075
Kind Code:
B2
Abstract:
Embodiments of the present invention disclose a method and a device for detecting and transmitting information. The method includes: obtaining, by a UE, at least one type of configuration information of an antenna port occupied by a D-PDCCH, which is configured on a base station side; determining, by the UE, a search space of the D-PDCCH; and detecting, by the UE, the D-PDCCH in the search space according to the antenna port configuration information. With the embodiments of the present invention, the UE can detect the D-PDCCH, and therefore data transmission is ensured. Furthermore, a blind detection of a PDCCH by the UE based on time-frequency resources in an existing system is extended to a spatial dimension, that is, an antenna port, thereby increasing the efficiency of resource utilization, so that the D-PDCCH can be detected in the spatial dimension.
