Abstract:
1. A method for detecting control signaling, comprising: obtaining, by a user equipment (UE), a transmission mode of a data channel configured by a base station; determining, by the UE, a first downlink control information (DCI) format and a second DCI format that are corresponding to the transmission mode, wherein physical downlink control channel (PDCCH) information corresponding to the first DCI format is transmitted in a precoding-based mode, and PDCCH information corresponding to the second DCI format is transmitted in a single-antenna port mode or transmit diversity mode based on non-precoding; and detecting, by the UE and in a subframe, the PDCCH information corresponding to the first DCI format and the second DCI format according to a mode in which the PDCCH information is transmitted.
