METHOD AND APPARATUS FOR SUPPORTING SEGMENTATION OF PACKETS FOR UPLINK TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To allow for higher data rates in the UL and reduce header overhead for UL transmissions.SOLUTION: An enhanced transport format combination (E-TFC) selection entity controls the concatenation of MAC SDUs into enhanced MAC-es PDUs. When a MAC SDU is received that is too large to fit into a selected enhanced MAC-es PDU payload, a segmentation entity segments the MAC SDU such that the MAC SDU segment fills the remaining payload available in the selected enhanced MAC-es PDU. The enhanced MAC-es PDU is then assigned a transmission sequence number (TSN) and multiplexed with other enhanced MAC-es PDUs to create a single enhanced MAC-e PDU that is transmitted on an E-DCH in the next transmission time interval (TTI).SELECTED DRAWING: Figure 4
