Abstract

The invention discloses a data unit transmission method and device, and belongs to the technical field of wireless communication. The method comprises steps of receiving a configuration command of data bearing issued by a base station; after receiving the configuration command, not adding sequence number SN fields in a packet data unit PDU packet header of a complete radio link control RLC non-conformation mode UM service data unit SDU included by the data bearing; and adding SN fields in the PDU packet header of the RLC UM SDU fields included in the data bearing. According to the invention, calculated amount is reduced and processing efficiency is improved.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710150400.4 and the invention title "data unit transmission method and device" filed with the China Patent Office on March 14, 2017, the entire contents of which are incorporated herein by reference. technical field [0002] The present disclosure relates to the technical field of wireless communication, and in particular to a data unit transmission method and device. Background technique [0003] With the rapid development of the wireless communication technology field, LTE (Long Term Evolution, long-term evolution technology) emerges as the times require. LTE is developed by 3GPP (3 rd The long-term evolution of the UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) technical standard formulated by the Generation Partnership Project (Generation Partnership Project), there is an RLC (Radio Link Control, radio link control) laye...
