Uplink data transmission method, terminal, network side device and system
An uplink data transmission method includes: transmitting uplink data by a terminal, wherein a packet data convergence protocol (PDCP) serial number (SN) of each data packet in the uplink data corresponds to a quality of service flow identifier (QoS flow ID) in a pre-set mapping relationship. The embodiments of the present invention are favourable for reducing the overheads of a QoS flow ID of uplink data and improving the transmission efficiency of the uplink data.
