wherein the n-th slot is a slot in which the eMBB UE sends the uplink data, and the n is a positive integer; the plurality of symbols comprises Z to X symbols; the X=t1+TA, the t1 is a time taken by UE to decode a preemption indication downlink control information (DCI) that is related to a capability of the eMBB UE, the TA is a timing advance value for the eMBB UE; and a value of the Z is pre-configured or configured by a network side;

or,

detecting the preemption indication message sent by the base station during a period in which the eMBB UE is sending uplink data;

wherein, in case of detecting, in the plurality of symbols before the n-th slot, the preemption indication message directed to the n-th slot, after the eMBB UE receives the uplink grant and before the eMBB UE sends the uplink data, the computer program is configured to be executed by a processor to further implement following step:

sending the uplink data in the n-th slot in case that the preemption indication message directed to the n-th slot is not received in X symbols before the n-th slot;

discarding a portion of the uplink data or all of the uplink data in the n-th slot in case that the preemption indication message directed to the n-th slot is received in the X symbols before the n-th slot;

wherein, in case of detecting the preemption indication message sent by the base station during a period in which the eMBB UE is sending the uplink data, the computer program is configured to be executed by a processor to further implement following step:

beginning to discard a portion of the uplink data or all of the uplink data currently being transmitted from a time instant of an X-th symbol after a time instant at which the preemption indication message is received;

wherein the X=t1+TA, the t1 is a time taken by UE to decode a preemption indication downlink control information that is related to a capability of the eMBB UE, and the TA is a timing advance value for the eMBB UE.

3. A non-transitory computer readable storage medium storing therein a computer program, wherein the computer program is configured to be executed by a processor to implement an indication method, and the method comprises:

detecting a preemption indication message sent by a base station, wherein the preemption indication message is configured to indicate, to the eMBB UE, a previous scheduled uplink transmission resource preempted by other services,

wherein the detecting the preemption indication message sent by the base station comprises:

detecting, in a plurality of symbols before an n-th slot, the preemption indication message directed to the n-th slot, after the eMBB UE receives the uplink grant and before the eMBB UE sends the uplink data;
