A service data packet transmission method, comprising: upon receipt of a scheduling command for an uplink resource transmitted from a network side device, acquiring attribute information of to-be-transmitted service data packets, the attribute information of the to-be-transmitted service data packets comprising a latency (41,51,111); and mapping the to-be-transmitted service data packets to the uplink resource in accordance with a latency requirement on the to-be-transmitted service data packets, and transmitting the to-be-transmitted service data packets on the uplink resource, characterized in that the mapping the to-be-transmitted service data packets to the uplink resource in accordance with the latency requirement on the to-be-transmitted service data packets and transmitting the to-be-transmitted service data packets on the uplink resource comprises: either a first manner or a second manner, in the first manner, determining whether a first transmission latency for a first scheduled resource indicated by a first scheduling command transmitted from the network side device meets the latency requirement on the to-be-transmitted service data packets, to acquire a determination result, and mapping the to-be-transmitted service data packets to the first scheduled resource or a second scheduled resource indicated by a subsequently-received second scheduling command in accordance with the determination result, and transmitting the to-be-transmitted service data packets on the first scheduled resource or the second scheduled resource, wherein a second transmission latency for the second scheduled resource is different from the first transmission latency for the first scheduled resource; or in the second manner, determining the to-be-transmitted service data packets corresponding to a transmission latency for a scheduled resource indicated by a currently-received scheduling command in accordance with a preconfigured correspondence between latency requirements on service data packets to be transmitted and scheduled resources with at least two transmission latencies, mapping the to-be-transmitted service data packets to the scheduled resource, and transmitting the to-be-transmitted service data packets on the scheduled resource. upon receipt of a scheduling command for an uplink resource transmitted from a network side device, acquiring attribute information of to-be-transmitted service data packets, the attribute information of the to-be-transmitted service data packets comprising a latency (41,51,111); and mapping the to-be-transmitted service data packets to the uplink resource in accordance with a latency requirement on the to-be-transmitted service data packets, and transmitting the to-be-transmitted service data packets on the uplink resource, characterized in that the mapping the to-be-transmitted service data packets to the uplink resource in accordance with the latency requirement on the to-be-transmitted service data packets and transmitting the to-be-transmitted service data packets on the uplink resource comprises: either a first manner or a second manner, in the first manner, determining whether a first transmission latency for a first scheduled resource indicated by a first scheduling command transmitted from the network side device meets the latency requirement on the to-be-transmitted service data packets, to acquire a determination result, and mapping the to-be-transmitted service data packets to the first scheduled resource or a second scheduled resource indicated by a subsequently-received second scheduling command in accordance with the determination result, and transmitting the to-be-transmitted service data packets on the first scheduled resource or the second scheduled resource, wherein a second transmission latency for the second scheduled resource is different from the first transmission latency for the first scheduled resource; or in the second manner, determining the to-be-transmitted service data packets corresponding to a transmission latency for a scheduled resource indicated by a currently-received scheduling command in accordance with a preconfigured correspondence between latency requirements on service data packets to be transmitted and scheduled resources with at least two transmission latencies, mapping the to-be-transmitted service data packets to the scheduled resource, and transmitting the to-be-transmitted service data packets on the scheduled resource.
