1. A downlink channel decoding method, comprising:
determining, by a user equipment, a resource unit occupied by a demodulation reference signal DMRS, the determining comprising determining, by the user equipment based on a first DMRS pattern and in a subframe in which there is a first signal transmitted, a resource unit occupied by the DMRS; and determining, based on a second DMRS pattern and in a subframe in which there is no first signal transmitted or no first channel transmitted, a resource unit occupied by a DMRS, wherein a time domain symbol occupied by the first DMRS pattern is not completely the same as a time domain symbol occupied by the second DMRS pattern; and
decoding, by the user equipment, a downlink channel based on the DMRS transmitted on the resource unit.
