Description
Technical field
The present invention relates to the channel allocation technique field, be specifically related to upload control slot allocation method, system and travelling carriage.
Background technology
In existing GPRS (GPRS), enhancing GPRS (EGPRS) technology, can set up interim connection the, i.e. Temporary Block Flow (TBF) between travelling carriage in the grouped data repeating process (MS) and the network.GPRS, EGPRS support a MS to have a plurality of TBF to connect in one direction.The time slot of distributing to GPRS is called Packet Data Channel (PDCH), and a TBF can use Radio Resource on one or more PDCH, also can be a plurality of TBF simultaneously multiplexing on same PDCH.In GPRS, EGPRS, each TBF has the grouping assist control channel (PACCH) of a correspondence to comprise: descending PACCH and up PACCH, this PACCH only may be mapped on the PDCH at its corresponding TBF place.
At present, be radio block (Block) at the minimum scheduling unit of the data of physical layer transmission, each Block is made up of 4 time slots, and 4 time slots lay respectively in 4 continuous time division multiple accesses (TDMA) frame, and the propagation delay time of each Block all is 20ms.High level data is encapsulated in the Block and transmits, and each Transmission Time Interval (TTI) duration is 20ms at present, and promptly each high level data piece has the time delay of 20ms at least.In order to reduce propagation delay time, the RTTI technology has been proposed.The RTTI overall thought is: keep the big or small constant of each Block, reduce TTI by utilizing multicarrier or multi-slot.Wherein, utilize principle that multi-slot reduces TTI as shown in Figure 1, in Fig. 1, piece B1 adopts the technical transmission before the RTTI, is positioned on 4 continuous T DMA frames, and every frame takies 1 time slot, and then the TTI of B1 equals 20ms; Piece B2 and piece B3 adopt the RTTI technical transmission, and B2 is positioned on 2 continuous tdma frames, and every frame takies 2 continuous time slot, and then the TTI of B2 equals 10ms; In like manner, the TTI of B3 equals 5ms.
Owing to introduce the RTTI technology, the TBF that can occur having different TTI is called multipling channel simultaneously in the situation of same channel with the channel that transmits the TBF of different TTI simultaneously; And the channel that will only transmit the TBF of a kind of TTI is called non-multipling channel.In Fig. 1, transmit the TBF of 10ms and 20ms on PDCH0, the PDCH1 simultaneously, then PDCH0, PDCH1 are multipling channel; Only transmit the TBF of 20ms on the PDCH3, only transmit the TBF of 10ms on PDCH6, the PDCH7, then PDCH3, PDCH6, PDCH7 are non-multipling channel.
When adopting the RTTI technology, determine TTI usually in the following way:
1, for a certain given MS, the TTI of the TBF that disposes on same channel must be identical; The TTI of the TBF that disposes on different channels can be identical, also can be different.In Fig. 1, the TBF of the 10ms on the PDCH4 and the TBF of 5ms can not belong to same MS, and should belong to different MS.
2, for a certain given MS, the TTI of upload control piece is identical with the TTI of corresponding descending TBF or controll block.Shown in Fig. 2-1, the TBF that network side sends the descending 20ms carry effective RRBP to MS is when carrying out poll to this TBF, and then MS needs to send the upload control piece of the 20ms that indicates whether to receive this TBF on the time slot that this descending TBF uses; In like manner, shown in Fig. 2-2, when network carried out poll to the TBF of descending 10ms, MS then needed to send the upload control piece of 10ms on the time slot that this descending TBF uses.
But, the restriction that MS is subjected to multislot capability is promptly: MS can only occupy the time slot of some in a tdma frame transmission duration, therefore, MS can't accomplish that the up PACCH piece of each descending TBF correspondence all is mapped on the time slot at corresponding descending TBF or controll block place, this moment, network side was by when carrying out resource distribution for descending TBF and reshuffling, for MS distributes the upload control time slot, after this MS sends the upload control piece on this upload control time slot.
Fig. 3 is the flow chart that MS distributes the upload control time slot for existing network side, and as shown in Figure 3, its concrete steps are as follows:
Step 301: network side sends grouping downlink assignment/descending assignment message of many TBF to MS, and this message is carried the timeslot number (TN) of upload control time slot, can send the upload control piece on the time slot of this timeslot number indication with instruct MS.
Each time slot has a timeslot number (TN, Timeslot Number), to identify this time slot.
After step 302:MS receives this message, preserve the timeslot number of the upload control time slot that this message carries.
Step 303: network side sends the descending TBF1 that carries effective correlation reserved block period (RRBP) to MS, with expression descending TBF1 is carried out poll.
After step 304:MS received this descending TBF1, affirmation (ACK) message that this descending TBF1 has been received in indication returned to network side by network side in the step 301 for self distributed time slot.
Step 305: network side sends the descending TBF2 that carries effective RRBP to MS.
After step 306:MS received this descending TBF2, the affirmation message that this descending TBF2 has been received in indication returned to network side by network side in the step 301 for self distributed time slot.
Step 307: network side need to determine to be again MS distribution upload control time slot, reshuffles/many TBF time slot reconfiguration message to MS transmission grouping time slot, and this message is carried the timeslot number of new upload control time slot.
After step 308:MS receives this message, preserve the timeslot number of the new upload control time slot that this message carries.
Step 309: network side sends the descending TBF1 that carries effective RRBP to MS.
After step 310:MS receives this descending TBF1, indication has been received the affirmation message of this descending TBF1 returns to network side by network side in the step 307 for the new time slot that self distributes.
Step 311: network side sends the descending TBF2 that carries effective RRBP to MS.
After step 312:MS receives this descending TBF2, indication has been received the affirmation message of this descending TBF2 returns to network side by network side in the step 307 for the new time slot that self distributes.
The shortcoming of prior art is as follows:
Network side is when distributing the upload control time slot for MS, and this upload control time slot is only indicated 1 time slot, and does not indicate employed TTI when sending the upload control piece on this time slot.And network side is distributed to MS with two time slots with the right form of time slot sometimes when distributing time slot for MS, and after this network side is defaulted as that two time slots of this time slot centering always use in pairs.And be that upload control time slot that MS distributes is when being time slot of time slot centering at network side, MS but can't determine send a upload control piece with big TTI on this time slot, still be the time slot that comprising this time slot on send a upload control piece with less TTI, may cause network resources waste like this.
As shown in Figure 4, network side is MS allocation of downlink 20ms TBF1 and 10ms TBF2, owing to limited by the MS multislot capability, MS can't send the upload control piece corresponding with TBF1 on the ascending time slot TN1 of descending TBF1 correspondence, at this moment, network side is that the upload control time slot that descending TBF1 distributes is that time slot is right: the TN2 among TN2 and the TN3.When network side is provided with RRBP and carries out poll in descending TBF1, MS can't determine it is to adopt the TTI consistent with the TTI of descending TBF1 on TN2, to the affirmation of network side feedback 20ms/do not confirm (ACK/NACK) message, still time slot that TN2 and TN3 constitute on to the ACK/NACK message of network side feedback 10ms, when being chosen in TN2, goes up when network side feeds back the ACK/NACK message of 20ms MS, network side does not also know that TN3 is unoccupied, therefore can again TN3 not distributed to other MS and use, so just cause the channel resource waste.
