1. A data transmission method, performed by a network side device, comprising:
sending a first downlink control information (DCI) for scheduling a first transmission for a User Equipment (UE);
wherein in a case that a relation between a second transmission having been scheduled or configured for the UE and the first transmission scheduled by the first DCI satisfies a preset condition, a time instant of sending the first DCI is not later than a time instant with a time duration T before a starting symbol of the second transmission for the UE, wherein a value of the time duration T is configured or determined before sending the first DCI, or is obtained according to configuration information before sending the first DCI;
the preset condition comprises at least one of following conditions:
the first transmission and the second transmission are in a same cell or on a same carrier, a transmission resource of the first transmission overlaps a transmission resource of the second transmission, and a priority of the first transmission is higher than a priority of the second transmission; or
the first transmission and the second transmission are in a same cell or on a same carrier, the first transmission and the second transmission are transmitted on different time domain resources in a same slot, reception or sending of more than one transmission in a same slot in a same cell or on a same carrier is not supported at a terminal side, and a priority of the first transmission is higher than a priority of the second transmission.
