Embodiment
In the prior art, the MAC-hs entity of UTRAN side will be distributed to different priority queries according to its priority from the MAC-hs SDU on upper strata, only transmit a MAC-hs SDU in the priority query in each MAC-hs PDU.Upper-layer protocol to MAC-hs entity output MAC-hsSDU, also need be submitted MAC-hs SDU to upper-layer protocol according to same order in the UE side in order, to realize transparent transmission.But in the process of transmission MAC-hs PDU, can not guarantee that MAC-hs SDU reaches UE in order.In the MAC-hs of UE side entity, corresponding to each priority query of UTRAN side a reorder queue is arranged all, the MAC-hs SDU among the MAC-hs PDU of reception is output the reorder queue to correspondence, exports upper-layer protocol after rearrangement to.
For the reorder queue under can discerning MAC-hs SDU in the UE side, MAC-hs PDU of the prior art adopts frame structure shown in Figure 1.MAC-hs PDU comprises the MAC-hs header and as the one or more MAC-hs SDU of load, and possible byte of padding.In the MAC-hs header, comprise VF (Version Flag, version identifier) field, formation ID (QID, Queue Identifier), TSN (Transmission Sequence Number, transmission sequence number) field and one or more SID (Size index identifier, MAC-hs SDU or the indication of MAC-d PDU size) field, N field and F field.
In the MAC-hs header in Fig. 1, the VF field is made as 0, and this version keeps; The ID of the priority query under the MAC-hs SDU that formation id field indication is carried or, because the ID of priority query and the ID of receiving terminal reorder queue, length is 3bit (position); The TSN field is indicated the transfer sequence ID of this MAC-hs PDU on HS-DSCH (High Speed Downlink Shared Channel, high speed descending sharing channel) channel, is used to reorder and submits in proper order with support, and length is 6bit; The size of each SDU in continuous N AC-hs SDUs set of SID field indication, each MAC-hs SDU size and SID relation is disposed by RRC (Radio Resource Control, Radio Resource control) high level, and independent to each priority query; The indication of N field has the length of onesize continuous SDUs set; The F field indicates whether that the back also has other SID fields, and length is 1bit.
As seen, the UE that receives MAC-hs PDU can learn which reorder queue the MAC-hs SDU that wherein carries should be put into from the formation id field its header; And in same reorder queue, UE can learn the correct order of MAC-hs SDU the formation from the TSN field, thereby be achieved the order of upper-layer protocol is submitted function.
Among the present invention, when the data volume of high-priority queue is less than the transmission block size determined according to channel quality when certain transmits,, can make the base station that the MAC-hs SDU of next priority query is dispatched in order to make full use of the transmittability of eating dishes without rice or wine.Simultaneously, the UTRAN side need notify the MAC-hs SDU that carries among its MAC-hsPDU of UE to belong to which reorder queue.Because the reorder queue of UE side and the priority query of UTRAN side have one-to-one relationship, formation under the MAC-hs SDU both can be a priority query, also can be reorder queue, be referred to as priority query or reorder queue with formation under the MAC-hs SDU in the present invention.
MAC-hs multi-queue transmission method of the present invention at step S210, receives the channel quality information of UE feedback in the flow process of UTRAN side as shown in Figure 2.The channel quality information that UE feeds back to the UTRAN side can provide foundation for base station dispatcher distributes the concrete size of MAC-hs PDU, as RTBS.
At step S220, determine the block size of the MAC-hs PDU of this transmission according to the channel quality information of UE feedback.
At step S230, the current priority query that MAC-hs SDU to be transmitted is arranged of base station dispatcher scheduling with limit priority.Identical in step S210 to S230 and the prior art.
At step S240, judge whether that the data volume of the MAC-hs SDU that dispatched reaches the capacity that this transmission can be carried, if, execution in step S250; If not, change step S230, continue the priority query of the next non-NULL of scheduling.
The capacity that this transmission can be carried is the data volume of load among the MAC-hs PDU, when the indicated MAC-hs PDU block size of the channel quality of UE feedback was identical, the capacity that this transmission can be carried may be because of the frame format of MAC-hs PDU, the difference difference of header information data amount.
At step S250, the MAC-hs SDU that is dispatched is formed MAC-hs PDU, and in MAC-hs PDU, show the affiliated formation of the MAC-hs SDU in its load.
Corresponding to different MAC-hs PDU frame formats, can there be several different methods in MAC-hs PDU, to indicate the affiliated formation of it MAC-hs SDU that comprises, the most direct for example a kind of mode is to indicate formation under it separately for each MAC-hs SDU.The efficient of taking all factors into consideration the header expense of MAC-hs PDU and form conciliating parsing MAC-hs PDU, the present invention recommends the affiliated formation of adopting MAC-hs PDU header form shown in Figure 3 to indicate MAC-hs SDU.
In the MAC-hs of Fig. 3 header, fields such as QID, TSN, SID, N and F are used for describing each formation, and are identical in its implication and arrangement and the prior art, promptly begin with the QID field, are followed successively by TSN field, SID field, N field and F field.Whether the F field also has the MAC-hs SDU of other these formations by set with behind the MAC-hs SDU that represents current SID correspondence that resets, last F field of each formation should be changed to and reset.
After last F field of each formation, increase the QF field, its effect is similar to the F field, be illustrated in the load of MAC-hs PDU when the set of QF field, the MAC-hs SDU of current queue so far finishes in this transmission, and follow-up is MAC-hs SDU in another formation; The MAC-hs SDU that represents current queue when the QF field resets so far finishes in this transmission, and current queue is last formation that is scheduled in this transmission.When the set of QF field, in the header of MAC-hs PDU above-mentioned each description field of the next formation that is scheduled.
When the MAC-hs SDU that base station MAC-hs entity generation MAC-hs entity basis is scheduled generates MAC-hs PDU, earlier at QID

1mInsert descriptor in the field successively, wherein F to MAC-hsSDU in first formation
1mField resets, and is expressed as last MAC-hsSDU of first formation.When comprising the MAC-hs SDU of a plurality of formations among the MAC-hs PDU, F
1mQF field set after the field, the QID of second formation of interpolation after this QF field

2nField.F
2nField resets, if only carried the MAC-hs SDU in two formations among this MAC-hsPDU, then QF field thereafter resets; Otherwise QF field set thereafter, and the description field that begins to add the 3rd formation.
At step S260, the MAC-hs PDU that generates is carried out downlink transfer.
The above-mentioned MAC-hs transmission method of the present invention is not only applicable to single carrier TDD (Time DivisionDuplex, time division duplex) HSDPA system, equally is applicable to multi-carrier-wave TDD HSDPA system yet.Single carrier TDD HSDPA system to the R5 standard, the HARQ entity that is used for carrying out MAC-hs PDU transmission has 8 HARQ processes, each HARQ process can send MAC-hs PDU, and each MAC-hs PDU carries the TSN of oneself, is used for the receiving terminal rearrangement and uses.Will realize that so whole HARQ processes send continuously, the maximum of TSN should be not less than 8.
Simultaneously, the maximum of TSN is also relevant with the size that sends window and/or receiver window.UE based on TSN to the receiver window processing of sliding, if TSN drops on outside the receiver window scope of UE, before UE just drops on behind the window still window according to TSN so, carry out associative operation, if before TSN drops on window, UE will be to the front slide receiver window, those drop on the TSN behind the receiver window, and UE will no longer receive.After if TSN drops on window, UE will no longer receive this TSN; For the UTRAN side, if dropping on, the TSN that retransmits sends outside the window scope, the UTRAN side will stop to retransmit this Frame; As seen, the TSN that carries of MAC-hs PDU is the key factor that influences UE and the proper communication of UTRAN side.UE is responsible for the reception of MAC-hs PDU, and the transmission of MAC-hs PDU is responsible in the base station, and it is identical with the receiver window size generally to send window.
Send the window size and limited the base station and send the maximum of TSN continuously, thereby limited the ability that the base station utilizes bandwidth of air-interface.Maximum in current R5 standard to send the window size be 32, that is to say that the base station can not wait for that receiving terminal is confirmed and sent TSN continuously is 0 to 31 MAC-hs PDU.For the length that prevents TSN field in the current standards of reason such as backrush is 6bit, the TSN maximum of support is 63, can satisfy the demand of single carrier HSDPA system.
The peak rate that single carrier is supported can not satisfy following high speed business requirement.In multi-carrier-wave TDD HSDPA system, the sub-district need be supported single carrier and multicarrier user simultaneously, the frame structure of the up-downgoing physics shared control channel of multi-carrier-wave TDD HSDPA can not be changed easily, thereby cause data being shunted by MAC-hs, the MAC-hs SDU that is about to transmission is assigned to different carrier waves, each carrier wave independently encode mapping, modulate transmission.Then need the ability that receives a plurality of carrier data simultaneously for UE, after each carrier wave is independently deciphered processing, merge by the MAC-hs of UE side.Each carrier wave all has a HARQ entity like this, guarantees the correct reception of MAC-hs PDU on this carrier wave.
Because in the multi-carrier-wave TDD HSDPA system, the HARQ entity on each carrier wave sends independently and receives.Therefore, when all HARQ processes sent continuously between base station and UE in multicarrier system, HARQ carried out the product of quantity on the carrier number that the MAC-hs PDU number of transmission the time is used simultaneously for transmission and the carrier wave.Like this, the scope of each formation TSN is at least 0 and subtracts 1 to this product, can guarantee that just receiving terminal can carry out correct reordering to the MAC-hs SDU that receives.And, usually can the TSN maximum be set to this product and subtract 1 twice in order to prevent backrush.Simultaneously, the bit wide of the TSN field of each formation also should be complementary with set TSN maximum in the MAC-hs PDU frame format.
For example, general TD-SCDMA (Time Division Synchronous Code Division MultipleAccess, TD SDMA) carrier number that transmits simultaneously between cell base station and UE is 6, HARQ process number also increases and increases along with carrier number, can reach 48 processes, if all process sends continuously, the scope of TSN can reach 0 to 47.The multi-carrier HSDPA system will increase much than the bandwidth of air-interface of single carrier simultaneously, the also corresponding expansion of scope that sends window could allow the base station send and make full use of bandwidth of air-interface, the transmission window of original standard is 32 to the maximum, the maximum of transmission window size can be set with carrier number and be directly proportional in the multicarrier system, i.e. 32 * 6=192.
As from the foregoing, original TSN scope 0 to 63 makes that reordering of receiving terminal is very difficult.The TSN maximum generally is maximum two demultiplications 1 that send the window size, promptly 383.In the header of MAC-hs PDU, the bit wide of TSN field can be supported its maximum 383 during for 9bit.And if TSN length is long, can take interface-free resources, be 9bit so the present invention recommends to set the bit wide of TSN field.
In addition, because the frame format of eating dishes without rice or wine among the present invention is different from the frame format in the existing standard, and in this frame format the VF field be 0 and this version keep, VF field in the MAC-hs header in the frame format of eating dishes without rice or wine of the present invention can be made as 1, the sign multi-carrier HSDPA, multicarrier UE can identify by this and know that this Serving cell can provide multi-carrier service like this.
To sum up, the MAC-hs PDU that recommends among the present invention eats dishes without rice or wine frame format to having the modification in the standard now or adding as shown in the table:
| Sign | Newly-increased/as to revise | The position | Implication |
| VF | Revise | Begin most | |
| TSN | Revise, increase to 9 bit | Be positioned at the QID back | Guarantee that by increasing bit wide UE can obtain maximum downstream rate |
| QF | Newly-increased | Be positioned at F sign back | Whether the sign back has other queuing messages; Being that 1 sign back also has other queuing messages, is that 0 sign does not have other queuing messages |
| QID2, TSN2 etc. | Newly-increased | Be positioned at QF sign back | Identify the MAC-hs SDU information (QF be invalid) of other formations at 0 o'clock |
In the UE side, when UE receives the MAC-hs PDU that generates with the above-mentioned frame format of eating dishes without rice or wine, can resolve according to following steps:
A.UE reads QID successively
1, TSN
1, SID
1Etc. information, as the foundation of resolving the MAC-hsSDU in this formation; After the SID territory obtains and finishes, enter the b step;
B.UE reads the F field, if the set of F field represents that all SID territories of this formation are finished, enters the c step; If the F field resets, continue to read the information in the next SID of this formation territory;
C. read the QF field after the F field,, then change step a if follow-up other formations MAC-hs SDU information that has is represented in the set of QF field; If the QF field resets, represent follow-up do not have other queuing messages, execution in step d;
D.UE begins the MAC-hs SDU of each formation is resolved according to the load information of the MAC-hs PDU that is obtained, and is distributed to corresponding reorder queue.
The structural representation of many formations of MAC-hs transmitting device of the present invention as shown in Figure 4, priority query's module 410 is connected with scheduler module 420 and PDU generation module 430 respectively; Scheduler module 410 is connected to PDU generation module 420 and channel quality module 440 respectively; PDU generation module 420 connects transport module 430.
Comprise at least one priority query in priority query's module 410, depositing MAC-hs SDU to be sent in each priority query with equal priority corresponding to certain UE.
The channel quality information that channel quality module 450 bases receive from UE is determined the block size of the MAC-hs PDU of this transmission, and exports the block size of determining to scheduler module 420.
Which MAC-hs SDU in the scheduler module 420 decision priority query modules 410 carries out this transmission.Scheduler module 420 is at first dispatched current non-empty queue with limit priority, and when the data volume of higher priority queues can not satisfy the capacity of this transmission, 420 pairs of lower non-NULL priority queries of scheduler module dispatched.When the MAC-hs SDU that is dispatched can satisfy this transmission, scheduler module 420 will be carried out the MAC-hs SDU notice PDU generation module 430 of this transmission.Scheduler module 420 is calculated the capacity that this transmission can be carried according to the block size from channel quality module 450 inputs.
The present invention increases the QF field in the header of MAC-hs PDU, to support the MAC-hs SDU of MAC-hs a plurality of formations of carrying in once transmitting, provide with existing standard maximum compatibility in improved the utilance of interface-free resources, be particularly useful for the multi-carrier HSDPA system.In addition, the present invention expands the bit wide of TSN field in the MAC-hs PDU header, has prevented the too small problem that reorders that may cause receiving terminal under multi-carrier HSDPA of TSN maximum that existing standard is supported.
Above-described embodiment of the present invention does not constitute the qualification to protection range of the present invention.Any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection range of the present invention.
