['1. A demodulation reference signal transmission apparatus, comprising: • a transmitter (300), configured to send a configuration indication to a user equipment UE, wherein the configuration indication is used to instruct the UE to send a demodulation reference signal, DMRS, before scheduling the UE to perform a transmission on a Physical Uplink Shared Channel, PUSCH, wherein the DMRS is a DMRS that does not depend on uplink data; and • a receiver (301), configured to receive the DMRS sent by the UE.']
