Description
Technical field
The present invention relates to communication technical field, particularly a kind of data transmission processing method and system.
Background technology
In 3-G (Generation Three mobile communication system), for the upstream packet business of higher rate is provided, improve the availability of frequency spectrum, 3GPP (3rd Generation Partnership Project, third generation partner plan) at WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA) introduced high speed uplink packet access (HSUPA in the standard of system, High Speed Uplink PacketAccess) characteristic, be up enhancing characteristic, the ascending reinforcement system so the HSUPA system is otherwise known as.
In HSUPA system related protocol, RLC (Radio Link Control, Radio Link control) layer is divided into 3 kinds of RLC entities: transparent mode entity, Unacknowledged Mode entity, affirmation mode entity.For Unacknowledged Mode RLC entity, 3GPP agreement regulation, network can be to RLC PDU (Radio LinkControl Packet Data Unit, Radio Link control Packet Data Unit) disposes a plurality of transformats, select a suitable transformat notice rlc layer group to be bundled into RLC PDU by MAC (Media Access Control, medium access control) layer.
But under the Unacknowledged Mode in of the selection of MAC layer to RLC PDU form, agreement does not propose concrete method, is an important step in the TD-HSUPA transfer of data and select suitable R LC PDU form.Because if the form of RLC PDU is in case selected, in the process that RLC SDU (RadioLink Control Service Data Unit, Radio Link control Service Data Unit) group is bundled into RLC PDU, just inevitably use the remaining space after SDU has been adorned in the filling bit filling.Same, after MAC layer transmission block size is selected, is bundled into by RLC PDU group and also inevitably uses filling bit in the process of MAC layer transmission block and fill MAC layer transmission block.So, if in the time of reducing rlc layer and MAC layer and generate RLC PDU and MAC layer transmission block with filling bit, data cached at the more multiple rlc layers of every frame energy, just can utilize physical resource to transmit more upper layer data more fully, improve the data transmission efficiency of rlc layer and MAC layer.
In the existing data transmission procedure, the MAC layer can select a suitable transformat notice rlc layer group to be bundled into RLC PDU, in selection course, consider the data cached size that to transmit, therefore, the situation that rlc layer and MAC layer transmission block are wasted usually occurs, the data transmission efficiency of rlc layer and MAC layer is lower.

A42, if N1j≤N2j, illustrate and under this form, can hold this predetermined logic channel by MAC-e PDU all are data cached, then note the value of Sj * N1j;
If N1j＞N2j, illustrate and under this form, can't hold this predetermined logic channel by MAC-e PDU all are data cached, then calculate MAC-e PDU open ended predetermined logic channel buffer memory number under this form to be: Sj * N2j-RLC layer header overhead;
If also have the PDU form not check, forward steps A 41 to and check next form; Otherwise forward steps A 43 to.
A43, check out all PDU forms of this predetermined logic channel after, can make MAC-e PDU hold all data cached PDU forms of this predetermined logic channel if exist, then select the preferred transformat of the PDU form of corresponding Sj * N1j minimum as this predetermined logic channel; (MAC-e PDU under this preferred transformat, can use minimum space to hold this predetermined logic channel all are data cached, can make like this that remaining space is as much as possible to hold the data cached of next predetermined logic channel)
If do not exist to make MAC-e PDU hold all data cached PDU forms of this predetermined logic channel, then select the preferred transformat of corresponding (Sj * N2j-RLC layer header overhead) maximum PDU form as this predetermined logic channel.
A5, MAC layer will be determined the result notification rlc layer.
A6, rlc layer according to the preferred transformat of each predetermined logic channel, are concatenated into RLC PDU with the RLC SDU segmentation on each predetermined logic channel respectively, pass to the MAC layer.
Group was bundled into MAC-e PDU after A7, MAC layer added head portion with RLC PDU, finally issued physical layer.
