Abstract

The present invention provides a service data transmission method, a terminal, and a network-side device; the method includes: when receiving an uplink resource scheduling command sent by the network-side device, acquiring attribute information of the current service data packet to be transmitted; wherein, the The attribute information of the service data packet includes: delay; according to the delay requirement of the current service data packet to be transmitted, the service data packet to be transmitted is mapped to the uplink resource for transmission. In the solution of the present invention, when the UE has the ability to process multiple TTIs (such as the ability to process 1ms TTI and short TTI at the same time), when receiving uplink resource allocation from the eNB, the UE can perform Map and transmit data to be transmitted on uplink resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a service data transmission method, device and network side equipment. Background technique [0002] In the LTE (Long Term Evolution) system, scheduling is performed between air interfaces, and the basic time unit for resource allocation and data transmission is TTI (Transmission Time Interval). Before the Rel-13 version, the length of TTI was 1ms (hereinafter referred to as 1ms TTI) . [0003] In the Rel-14 version, in order to better support delay-sensitive services, LTE introduces a shorter TTI (hereinafter referred to as short TTI), and the length of the short TTI is less than 1ms; [0004] It is currently confirmed that the uplink channels that support the use of short TTI transmission include at least the short physical uplink control channel (s-PUCCH, Short Physical Uplink Control CHannel) and the short physical uplink shared channel (s-PUSCH, Short Physica...
