Abstract: A method and a device for transmitting an uplink control channel are provided. A user equipment (UE) receives downlink data which is scheduled by a downlink control channel from a network device, where the downlink control channel is a downlink control channel corresponding to a serving cell, the serving cell is a serving cell of at least two serving cells configured for the UE, the at least two serving cells include one primary serving cell and at least one secondary serving cell. The UE selects identity information according to the downlink control channel. The UE generates a physical uplink control channel corresponding to the downlink data by using the selected identity information, and transmits the physical uplink control channel on a channel resource of the physical uplink control channel.

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.
