transmitting data to the UE or receiving data from the UE, with the activated scheduled time-frequency resources, after the predetermined time has elapsed from the UE having received the scheduling information.

4. The method of claim 1 , wherein the scheduling information further comprises at least one of a period for the scheduled time-frequency resources, a time-frequency location of the scheduled time-frequency resources, or a type of the scheduled time-frequency resources.

5. The method of claim 1 , wherein a priority of the semi-persistent scheduling is lower than that of the dynamic scheduling; and a priority of the scheduling information is higher than the priority of the semi-persistent scheduling, or the priority of the scheduling information is lower than the priority of the semi-persistent scheduling.

6. A network node for resource scheduling, being configured to:

obtain time-frequency resources scheduled for user equipment (UE); and

transmit scheduling information to the UE, wherein the scheduling information comprises the scheduled time-frequency resources and time information,

wherein the scheduling information is configured to indicate an activation time of the scheduled time-frequency resources and instruct the UE to use the scheduled time-frequency resources to transmit or receive data after a predetermined time has elapsed from the UE having received the scheduling information,

wherein the predetermined time is determined by the network node and the UE in advance through negotiation or is specified in specification or standard,

wherein the scheduled time-frequency resources are activated when the predetermined time has elapsed from the UE having received the scheduling information,

wherein the scheduling information has a predefined priority at least with respect to semi-persistent scheduling and dynamic scheduling,

wherein the time information is configured to instruct the UE to use the scheduled time-frequency resources to transmit or receive data at a time indicated by the time information, and

wherein

the time information is configured to trigger a first timer and a second timer configured at the UE at the same time when the UE has received the scheduling information, instruct the UE to use the scheduled time-frequency resources to transmit or receive data when the first timer expires, and indicate for the UE that the scheduled time-frequency resources are no longer available for the UE when the second timer expires, the second timer expires later than the first timer, the first timer is used for indicating the activation time of the scheduled time-frequency resources, and the second timer is used for indicating the deactivation time of the scheduled time-frequency resources, or

the time information comprises a first time offset and a second time offset, the first time offset is configured to instruct the UE to use the scheduled time-frequency resources to transmit or receive data at a time indicated by the first time offset, the second time offset is configured to indicate for the UE that the scheduled time-frequency resources are no longer available for the UE at a time indicated by the second time offset, and the time indicated by the second time offset is longer than the time indicated by the first time offset.

7. The network node of claim 6 , wherein the scheduling information is carried by downlink control information or RRC signaling.

8. The network node of claim 6 , wherein the scheduling information further comprises at least one of a period for the scheduled time-frequency resources, a time-frequency location of the scheduled time-frequency resources, or a type of the scheduled time-frequency resources.

9. The network node of claim 6 , wherein a priority of the semi-persistent scheduling is lower than that of the dynamic scheduling; and a priority of the scheduling information is higher than the priority of the semi-persistent scheduling, or the priority of the scheduling information is lower than the priority of the semi-persistent scheduling.

10. A method for resource scheduling, performed at a user equipment (UE) and comprising:

receiving, from a network node, scheduling information, wherein the scheduling information comprises scheduled time-frequency resources determined by the network node and time information, the scheduling information is configured to indicate an activation time of the scheduled time-frequency resources and instruct the UE to use the scheduled time-frequency resources to transmit or receive data after a predetermined time has elapsed from the UE having received the scheduling information, the scheduled time-frequency resources are activated when the predetermined time has elapsed from the UE having received the scheduling information, and the predetermined time is determined by the network node and the UE in advance through negotiation or is specified in specification or standard;

transmitting or receiving data with the activated scheduled time-frequency resources after the predetermined time has elapsed; and

transmitting or receiving, on the scheduled time-frequency resources, data at a time indicated by the time information,

wherein the scheduling information has a predefined priority at least with respect to semi-persistent scheduling and dynamic scheduling, and
