If the TSN that transmits Sequence Number of the next segmentation of the MAC-c PDU that waits until is discontinuous, then this segmentation is placed on the reorder queue wait earlier and reorders, recombinate again after the end of reordering by the time.
8. method as claimed in claim 6 is characterized in that,
CRNC carries out CRC with the CCCH message that obtains, and verification succeeds is then passed CCCH message Radio Link control RLC entity and is transmitted to the radio resource control layer rrc layer, otherwise directly abandons.
9. the method for claim 1 is characterized in that,
Said MAC-i entity is used for: accomplish and eat dishes without rice or wine the E-DCH scheduling of resource and mix re-transmission HARQ protocol function automatically; And will carry out demultiplexing from the MAC-i protocol Data Unit MAC-i PDU that eats dishes without rice or wine to receive; Obtain one or more MAC-is protocol Data Unit MAC-is PDU, and on the public MAC stream of Iub interface, these MAC-is PDU are transferred to CRNC or SRNC through the E-DCH Frame.
10. method as claimed in claim 6 is characterized in that,
Said MAC-is entity is used for: receive the E-DCH Frame from the public MAC stream of Iub interface; Take out MAC-is PDU wherein; Be distributed to corresponding reorder queue according to logical channel information, and in reorder queue, reorder according to the TSN information that transmits Sequence Number, the MAC-is PDU that TSN is continuous removes the PDU head; Obtain one or more MAC-is service data units, carry out the reorganization of MAC-c or d PDU and the CRC of MAC-c PDU.
