FIELD: data transmission.
SUBSTANCE: invention relates to means of data transmission. No less than two DMRS port groups configured by a network device are received. The target reference signal resource corresponding with each of the no less than two DMRS port groups is determined. Transmission parameters for transmitting data to the DMRS port group corresponding with the target reference signal resource are determined according to the target reference signal resource. A link for transmitting or receiving a reference signal on the target reference signal resource is determined as a link for transmitting data to the DMRS port group corresponding with the target reference signal resource. After the transmission parameters for transmitting data to each DMRS port group is determined, the data is transmitted to no less two DMRS port groups.
EFFECT: improved uplink channel transmission rate.
