Scheduling entity takies information such as physical channel quality indication that situation, subscriber equipment feed back according to subscriber equipment priority, UE capability, QoS requirement, measuring business volume report, buffering area and determines subscriber equipment that next Transmission Time Interval can distributing radio resource and the service data unit (SDU) in the pairing service priority formation of these subscriber equipmenies according to set dispatching algorithm, selects to distribute to the transport block size of this subscriber equipment from described transport block size.The business that can dispatch one or more subscriber equipmenies in a Transmission Time Interval, the pairing service priority formation of one of them subscriber equipment can have one or more.Present embodiment is that example describes with one of them user's treatment step.
Please refer to Fig. 4, there is shown present embodiment segmentation and multiplexing process process, and the ARQ protocol Data Unit after the segment processing, the HARQ protocol data unit frame form after the multiplexing process.As shown in the figure, frame format is made of jointly header and other data message, and an ARQ protocol Data Unit comprises a service data unit at most.
In the present embodiment, the ARQ protocol Data Unit is divided into two types of different length, has just obviously saved header overhead, but adopt long one type also to be fine for short header.The header of Class1 is shorter, comprises ARQ protocol Data Unit numbering SN (Sequence Number), Logic Channel Identifier LCID (Logical Channel ID), segmentation marker F (Flag) at least, can comprise other header Etc, and is as follows:
| SN? | LCID? | F? | Etc.? |
The segmentation marker F of the type data cell is false, represents that this protocol Data Unit is made up of a complete service data unit.
The information that type is 2 is longer, at least comprise ARQ protocol Data Unit numbering SN, Logic Channel Identifier LCID, segmentation marker F, section sequence number SI (Segment Index), final stage sign LSF (Last Segment Flag) whether, can comprise other header Etc.As follows:
| SN? | LCID? | F? | S1? | LSF? | Etc.? |
The segmentation marker F of this data cell type is true, represents that this protocol Data Unit is made up of the segmentation service data unit.Because a service data unit may be divided into multistage, which section SI represents with the section sequence number; If final stage, then LSF is true, otherwise LSF is false.The back segment part of the service data unit that this is intercepted is as the content that generates next ARQ protocol Data Unit.
When above-mentioned fragmentation feature entity carries out segment processing at a TTI to service data unit, specifically comprise following substep:
Step 310, the length of judging first service data unit that takes out adds short header (header that does not add qualification in the literary composition all refers to ARQ protocol data unit head information) length, after the length of rest parts service data unit adds long header after the perhaps last segmentation, whether deduct length L 0 after the HARQ protocol data unit head message length greater than described transport block length, if, execution in step 320, otherwise execution in step 330;
Step 320, to this service data unit segmentation, intercepted length L0 deducts the leading portion part of long header length, adheres to header in stem and forms ARQ protocol Data Unit type 2, finishes;
Step 330 forms ARQ protocol Data Unit Class1 after the stem of this service data unit is adhered to header;
Step 340 judges whether to also have the next service data unit that will send, if do not have, finishes, otherwise, take out next service data unit, carry out next step;
In this step, if do not have more service data cell and accumulation length less than described transport block size, direct generation ARQ protocol Data Unit just, not at the partially filled redundant bit of back segment to transport block size.Be the segmentation of the fragmentation feature entity support service data unit of present embodiment, do not support the serial connection and the filling of service data unit, these functions are finished by multiplexing functional entity.
Whether step 350, the accumulation length of judging this service data unit and having generated the ARQ unit add behind the short header greater than length L 0, if, execution in step 320, otherwise, execution in step 360;
Step 360 generates new ARQ protocol Data Unit Class1 after the stem of this service data unit is adhered to short header, return step 340;
The ARQ protocol Data Unit that generates is stored in the ARQ buffering area, the header of ARQ protocol Data Unit can be stored in different memory spaces with the service data unit that generates the ARQ protocol Data Unit, sets up corresponding relation by described ARQ sequence number mapping table.Described ARQ buffering area and described ARQ sequence number mapping table can be shared by ARQ entity, fragmentation feature entity, HARQ entity and multiplexing functional entity.
The ARQ entity is responsible for safeguarding described ARQ sequence number mapping table.The ARQ entity inserts a record at described ARQ sequence number mapping table after the fragmentation feature entity generates an ARQ protocol Data Unit.After the ARQ entity receives the reception success response message of subscriber equipment for the ARQ protocol Data Unit, check and whether all received reception success response message by all ARQ protocol Data Units of certain service data unit generation; If then the corresponding record in the ARQ sequence number mapping table is all stamped delete flag, and deletes the service data unit in these records described ARQ buffering area pointed.Deletion for record also can be handled according to timer or other service data unit drop policy.Newly-increased record can be inserted into the shared address space of record of being stamped delete flag.Inquiry for record position can be based on set searching algorithm.
The ARQ entity utilizes sliding window mechanism that the ARQ protocol Data Unit of above-mentioned generation is delivered to multiplexing functional entity in a Transmission Time Interval.The delivery of ARQ protocol Data Unit can not be actual data reproduction process, and only be the transmittance process of datarams pointer, because ARQ entity and multiplexing functional entity are arranged in same network node base station jointly, above-mentioned entity to a certain extent can sharing A RQ buffering area.
Described multiplexing functional entity support serial connection and filling function, above-mentioned ARQ protocol Data Unit is connected in series in order, form the HARQ protocol Data Unit after adhering to corresponding header, if the length after the serial connection less than transport block size, is then filled redundant bit to transport block size at back segment.
And HARQ protocol data unit head information comprises transmission sequence number TSN (TransmissionSequence Number), each the ARQ protocol Data Unit Length Indication LI (Length Indicator) that is comprised at least, the header H of each ARQ PDU of being comprised, can comprise other header Etc.May comprise filling information, filling information is added on the last of HARQ protocol Data Unit.
| ?TSN? | L1? | H? | Etc.? | ……? |
Can not duplicate the ARQ protocol Data Unit in the ARQ buffering area in the harq buffer district, can be set up the mapping relations of HARQ protocol data unit head information and its ARQ protocol data unit head information that is comprised by described HARQ sequence number mapping table, its actual data message can obtain in the ARQ buffering area by ARQ sequence number mapping table.
Described HARQ entity is responsible for safeguarding HARQ sequence number mapping table, when described multiplexing functional entity generates a HARQ protocol Data Unit, in described HARQ sequence number mapping table, insert a record by the HARQ entity, receive the HARQ ACK of receiving terminal subscriber equipment when described HARQ entity after, corresponding record is stamped delete flag, and newly-generated record can be inserted into the shared memory headroom of record of delete flag.Described HARQ entity is inquired about required record based on set searching algorithm.
ARQ protocol Data Unit retransmission process
After the ARQ entity is received the take defeat response message of subscriber equipment for certain ARQ protocol Data Unit, need be submitted to multiplexing functional entity to this ARQ association data cell again, generate by multiplexing functional entity and be submitted to physical layer by the HARQ entity behind the new HARQ protocol Data Unit and resend.Because physical channel conditions changed when the ARQ entity resend the ARQ protocol Data Unit, need the various scheduling decision factors of described scheduling entity COMPREHENSIVE CALCULATING, needed Radio Resource when retransmitting to satisfy this ARQ protocol Data Unit.For example can guarantee its resource requirement by improving strategies such as its priority, if can't satisfy really at next Transmission Time Interval resource requirement, can be deferred to again next Transmission Time Interval and dispatch, perhaps adopt other strategy, abandon as carrying out SDU.
If the new transport block size of selecting of described scheduling entity deducts after the HARQ header length ARQ protocol Data Unit greater than required re-transmission, then this ARQ protocol Data Unit can be multiplexing with other ARQ protocol Data Unit that need send, to generate new HARQ protocol Data Unit.The ARQ entity is supported the delivery according to the order of sequence and the non-delivery according to the order of sequence of ARQ protocol Data Unit.When the ARQ protocol Data Unit that is retransmitted and other ARQ protocol Data Unit were multiplexing, the sequence number of these ARQ protocol Data Units may be discontinuous, the operation that needs the subscriber equipment of receiving terminal to reorder.If the transport block size of current selection then carries out segment processing to this ARQ protocol Data Unit that need retransmit again again less than the ARQ protocol Data Unit that need retransmit.
In sum, the present invention has realized a kind of self-adapting data cladding method, supports the variable-length protocol Data Unit.Avoided the overhead that caused when above-mentioned functions lays respectively at two nodes in the 3-G (Generation Three mobile communication system).Existing method with respect in the 3G (Third Generation) Moblie long evolving system the invention provides more complete solution.Header overhead is littler, segmented mode is more flexible, realization is simpler and more direct, the memory by using rate is higher.Its memory management method of header and other data cell being set up mapping relations by the memory address pointer has made full use of the advantage that ARQ entity and HARQ entity are positioned at the base station jointly, saved memory space to greatest extent by memory shared, internal memory such as duplicates at processing expenditure when also having avoided the generation protocol Data Unit.The present invention has greatly improved system handles efficient and overall performance.
