transmitting service data according to the first DCI, wherein transmitting the service data according to the first DCI comprises: preempting at least a part of a first transmission resource of a first priority service so as to transmit service data of a second priority service, wherein a priority of the second priority service is higher than a priority of the first priority service;

wherein the preemption of the transmission resource of the first priority service is resource preemption in a symbol level;

wherein the preemption field is used for indicating user equipment (UE) of the first priority service that the transmission resource of the first priority service is preempted by the second priority service in response to determining that the preemption field has a first value; and

wherein the preemption field is used for indicating UE of the second priority service that the second priority service preempts the transmission resource of the first priority service in response to determining that the preemption field has a second value;

the method further comprising:

determining that the second priority service which preempts the transmission resource is a periodical service and periodically preempts at least a part of the first transmission resource of the first priority service in response to determining that the first DCI is successfully descrambled by using a first sequence; or

determining that the second priority service which preempts the transmission resource is a non-periodical service in response to determining that the first DCI is successfully descrambled by using a second sequence.

5. The data processing method according to claim 4 , wherein transmitting the service data according to the first DCI comprises:

abandoning transmission of the first priority service of which the transmission resource is preempted according to the first DCI.

6. The data processing method according to claim 4 , wherein

transmitting the service data according to the first DCI comprises one of the following:

preempting at least a part of the first transmission resource of the first priority service so as to transmit the service data of the second priority service in response to determining that one of the first priority service of which the transmission resource is preempted and the second priority service which preempts the transmission resource belongs to the UE and the preemption field has a first value;

abandoning transmission of the first priority service of which the transmission resource is preempted in response to determining that one of the first priority service of which the transmission resource is preempted and the second priority service which preempts the transmission resource belongs to the UE and the preemption field has a second value;

preempting at least a part of the first transmission resource of the first priority service so as to transmit the service data of the second priority service and abandoning transmission of the first priority service of which the transmission resource is preempted in response to determining that both the first priority service of which the transmission resource is preempted and the second priority service which preempts the transmission resource belong to the UE and the preemption field has the first value; or
