In the communication system of using above-mentioned technology, network side is the MS distributing radio resource in advance, so that MS utilizes institute's assigned radio resource, carries out information interaction with network side.For application layer, the data that transmit are cut apart or are combined into Radio Link control (RLC)/medium access controls (MAC) data block, and in data forwarding process, aloft transmit on the interface with Temporary Block Flow (TBF) form.Each TBF can go up at one or more Packet Data Channel (PDCH) and use Radio Resource.Based on above-mentioned thought, when carrying out the transmission of logic link control (LLC) frame, the LLC frame is cut apart or is combined in a series of RLC data blocks, and each RLC data block has the piece sequence number (BSN) that network side distributes, a plurality of RLC data blocks according to BSN by sequential delivery.
Generally, transmitting terminal and receiving terminal set in advance send window and receive window respectively, so that transfer of data.In essence, the beginning of window and end position all can be represented with the value of BSN.Successful transmission and reception along with data promptly receive the confirmation (ACK) message, and send window and receive window constantly move forward.
Communication system for supporting the delay sensitive business in order in time to obtain the affirmation message of data block, so that transmitting terminal in time starts re-transmission, adopts quick confirmation method to come the transmission situation of specified data piece usually.In quick confirmation method, from the radio block of carrying RLC data block, take out a part of space, and put into a bit map (Bitmap) in the space in this section as control messages.Comprise a BSN and a series of value among this Bitmap and be 0 or 1 binary numeral, wherein BSN is positioned at the beginning of Bitmap, be used to indicate first wrong RLC data block to occur, and whether correctly each binary numeral after the BSN all represent the transmission of corresponding data block.

From foregoing description as seen, in the present embodiment, network side is determined the channel resource that distributed according to the ability level of MS, determines the bit number that the pairing BSN of TBF of this foundation takies according to channel resource again, and directly is handed down to MS.Like this, because network side is determined the bit number that BSN takies according to the actual conditions of MS, then compare with fixing BSN size cases, the BSN requisite space in the present embodiment may be less, thereby can have more binary numeral to come designation data transmission situation among the Bitmap.
Embodiment 2
In the present embodiment, BSS divides timing carrying out down channel resources, window size is handed down to MS, BSS and MS all calculate the shared bit number of BSN according to window size, and when after this BSS and MS were sending/receiving RLC/MAC data block among the same TBF, all the bit number according to the BSN correspondence that calculates this moment packaged/resolves.
Fig. 4 shows the signaling process figure of resource allocation methods in the present embodiment.Referring to Fig. 4, this method comprises:
In step 401～402, the BSS paging request message of giving out a contract for a project under MS is carried out paging to MS, and indicates and begin to set up descending TBF; MS sends the bag channel request message that carries user ID and ability level information to BSS, the request channel resource.
In step 403, BSS is definite resource and the definite window size that is distributed of MS, and with the channel resource information and the window size that are distributed, is carried in the descending assignment message of bag, send to MS, MS calculates the shared bit number of BSN according to the window size that receives.
In this step, BSS parses user ID and ability level information from the bag channel request message that receives, be defined as the channel resource that this MS distributes, simultaneously, determine the transmission used among the descending TBF of this foundation and the big or small W of receive window according to channel resource, generally window size is positioned at 20 to 1024 scope.Then, BSS sends to MS by the descending assignment message of bag with channel resource information and window size.
After MS receives descending assignment message, from this message, parse channel resource information and window size, and calculate the bit number that this pairing BSN of TBF that sets up takies according to window size.Concrete computational methods are: earlier window size be multiply by 2, determine to represent the bit number of the binary numeral of the product that obtained then, this bit number is the shared bit number of BSN.For example, window size is 32, and then BSN takies 6 bits.
Because that set up here is descending TBF, then during the RLC/MAC data block of MS in receiving the descending TBF that sets up this moment, all resolve according to the BSN that receives in this step, thus acquisition transfer of data situation.
In step 404～405, MS sends bag page-response message and bag control acknowledge message to BSS, as the response of bag paging request message and the descending assignment message of bag.
So far, finish resource allocation flow process in the present embodiment.
In the present embodiment under the more situation of the channel resource that MS needs, also can in the bag channel request message of step 402, only carry part ability level information, and MS also sends the bag resource request message to BSS, carries remaining ability level information in this message.After BSS receives bag channel request message and bag resource request message, therefrom read complete ability level, determine channel resource according to the complete ability level that reads, and partial channel knowledge is put into the descending assignment message of bag of step 403, all the other channel informations and window size are put into the descending assignment message of the bag shown in the figure dotted line, send to MS.MS parses window size from wrap descending assignment message, and calculates the shared bit number of BSN.

In step 504～505, MS sends bag page-response message and bag control acknowledge message to BSS, as the response of bag paging request message and the descending assignment message of bag.
So far, finish resource allocation flow process in the present embodiment.
More than ask the situation of less channel resource for MS.If the channel resource that MS needs is more, then in the bag channel request message of step 502, only carry part ability level information, and MS carries remaining ability level information also to BSS transmission bag resource request message in this message.After BSS receives bag channel request message and bag resource request message, therefrom read complete ability level, determine channel resource according to the complete ability level that reads, and partial channel knowledge is put into the descending assignment message of bag of step 503, all the other channel informations and BSN pattern are put into the descending assignment message of the bag shown in the figure dotted line, send to MS.MS parses pattern from wrap descending assignment message, determine the shared bit number of BSN, in order to using.
In the present embodiment, network side also is to determine the bit number that BSN takies according to the actual conditions of MS, and then the BSN requisite space in the present embodiment is less, thereby can have more binary numeral to come designation data transmission situation among the Bitmap.What network side issued in the present embodiment in addition is the BSN pattern, can save to the required space of MS notice BSN information.
In the application of reality, the above embodiments 1 can also be combined with embodiment 3.Particularly, set in advance multiple BSN pattern, and BSN typical value and BSN take corresponding relation between the bit number under every kind of pattern.Network side is determined BSN typical value under BSN pattern and this pattern according to the channel resource that is distributed, and issues BSN pattern and BSN typical value by up assignment message.MS determines that according to the BSN pattern and the BSN typical value that receive BSN takies bit number, be that MS is an index with the BSN typical value that receives, the corresponding relation that BSN typical value and BSN under the BSN pattern that receives is taken bit number is retrieved, and obtains corresponding BSN and takies bit number.For example, table 2 shows BSN typical value and BSN under 11 bit modes and 7 bit modes and takies corresponding relation between bit number.
| The BSN typical value | 11 bit modes | 7 bit modes |
| 000 | 7 | 6 |
| 001 | 8 | 7 |
| 010 | 9 | 8 |
| 011 | 10 | 9 |
| 100 | 11 | 10 |
