Abstract: A system and method for transmitting a reference signal in a cell that uses an unlicensed frequency band. The method includes determining a candidate resource set that is used when a first reference signal is transmitted in the cell that uses the unlicensed frequency band, where the candidate resource set includes a preset resource and at least one flexible candidate resource, determining a first candidate resource that is used when the first reference signal is transmitted in the cell that uses the unlicensed frequency band, where a channel on the unlicensed frequency band corresponding to the first candidate resource is in an idle state, and the first candidate resource is the preset resource or a flexible candidate resource in the candidate resource set, and sending the first reference signal on the first candidate resource.

Abstract: A downlink channel decoding method, a downlink information transmission method, a user equipment, and a base station are provided. The downlink channel decoding method includes: determining, by a user equipment, a resource unit occupied by a DMRS; and decoding a downlink channel based on the DMRS transmitted on the resource unit. The present invention can enable different DMRS patterns to concurrently exist on an NCT carrier. In a downlink transmission process, a DMRS pattern used for downlink transmission is determined according to priorities of different channels and/or signals, which can ensure optimal performance of a high-priority channel and/or signal, and can further improve downlink transmission performance.
