Apparatus and method for transmitting data blocks based on priority

摘要

A particular protocol layer of the transmitting side (transmitter) initially receives service data units (SDUs) having the same priority through a single stream from an upper layer, processes these SDUs to generate protocol data units (PDUs) having different priorities, and uses respectively different transmission methods to transmit the generated PDUs over a radio interface in order to guarantee their respectively different quality of service (QoS) requirements.
