Description

Peaked distribution method of available soft channel bit and system
Technical field
The present invention relates to the peaked distribution technique of available soft channel bit of the communications field; Relate in particular to the peaked distribution method of available soft channel bit and the system of the automatic repeat requests of a kind of mixing (HARQ, Hybrid-Automatic Repeat reQuest) treatment progress.
Background technology
High speed downlink packet inserts (HSDPA; High-Speed Downlink Packet Access) technology can be improved power system capacity; And can significantly promote the descending user data rate of WCDMA (WCDMA), the downlink transmission data rate of 10Mbit/s can be in the bandwidth of a 5MHz be provided for Packet data service.
The HSDPA technology has been introduced a new transmission channel, and high speed descending sharing channel (HS-DSCH, High Speed Downlink Shared Channel) is in order to carry the load of HSDPA.The function that HS-DSCH provides has: according to fast dispatch, short transmission blanking time and the dynamic transport block size and the HARQ of the quick adapted transmission form of channel condition, giving consideration to channel quality and priority.
In HSDPA, the processing of HARQ has moved on in the Node B, so that the fastest response speed to be provided.Here, Node B is typically expressed as Node B.The HARQ mode that HSDPA uses is: Node B is sent a data block, begins then to wait for, until the feedback that receives from the affirmation/negative acknowledgment of subscriber equipment (UE, User Equipment).
In order to make full use of the intermittence during this period of time of waiting for the UE feedback, UE operation a plurality of independently HARQ treatment progress (HARQ process) can be set, different HARQ treatment progress started in the different transmission intercal time.Under the single carrier case, a UE can move 8 HARQ treatment progress at most; During two carrier wave maximum 16, and in the network of reality, be set to 6 usually.
When UE receives misdata, give Node B with clear and definite whether request retransmission through sending negative acknowledgment message.In case after UE received data retransmission, meeting before merge the information and the original information of receiving that retransmit earlier attempting to decode.HARQ uses 2 kinds to merge mechanism: follow the tracks of merging (Chase Combining) and incremental redundancy (Incremental Redundancy).Follow the tracks of the mechanism that merges and be used for retransmitting vicious packet, need to retransmit the whole grouping that makes a mistake, the bandwidth resources of waste are more than incremental redundancy mechanism; The mechanism of incremental redundancy is then selected correct bit from the grouping of original transmission and retransmission packet, the data block of re-transmission only contains the correction bit to original misdata, in the hope of in available bandwidth, reach maximum transmission benefit as far as possible.
As shown in Figure 1, the HARQ function is to be made up of twice rate-matched (Rate Matching) and a virtual incremental redundancy buffer memory (virtual IR buffer, virtual Incremental Redundancy buffer).Rate-matched is complementary the virtual IRbuffer of input bit and UE for the first time.Each HARQ treatment progress in the virtual incremental redundancy buffer memory available soft channel bit maximum (the maximum numberof soft channel bits available) or claim that the buffer memory size (Process MemorySize) of HARQ treatment progress indicated by high-level signaling.Here, said available soft channel bit maximum can be used N IRExpression.If the input bit number is greater than N IR, then punch; Otherwise do not carry out the first rate coupling.For the second time rate-matched is through punching or repeated operation, the Bit data of each Transmission Time Interval of HS-DSCH that the first rate coupling is exported, and the bit number in the physical channel frame that is mapped to HS-DSCH is complementary.
N IRIt is the key parameter of HARQ.Node B relies on this parameter can carry out appropriate rate-matched in each HARQ treatment progress, to encode.UE relies on this parameter can carry out appropriate decoding in each HARQ treatment progress, to obtain the proper data block message.For same HARQ treatment progress, Node B and UE must use same N IRValue, because, if N IRThe understanding of value and use do not keep in full accord between Node B and UE, then channel bit position and logic implication all confusion can take place, and can cause the problem of Code And Decode, such as, that Node B and UE use is not same N IRValue, then UE receives the result of Node B coding, can't normally decode.
In HSDPA, because the processing of HARQ moved on in the Node B, so the N of each HARQ treatment progress IRDetermine by Node B.In the foundation or reprovision process of HS-DSCH, Node B is passed through node B application part (NBAP, Node B Application Part) high-level signaling the N of each HARQ treatment progress IRInformation is told radio network controller.Then, radio network controller is with the N of this each HARQ treatment progress IRInformation is through Radio Resource control (RRC, Radio Resource Control) high-level signaling notice UE.Like this, for same HARQ treatment progress, Node B and UE use the same N of appointment IRValue.
In the prior art, Node B is distributed N IR, or be called HARQ Process Memory Size following dual mode arranged:
One, implicit expression: as long as this moment, Node B was returned the number of the HARQ treatment progress of distribution; Node B and UE; Based on total bit number of the pairing soft channel of UE ability rating number, just obtain the employed Process Memory of each HARQ treatment progress Size divided by the HARQ treatment progress.
For example, when the number of Node B indication HARQ treatment progress equaled 6, the value of the Process Memory Size of each HARQ that Node B and UE calculate correspondence under the total bit number situation of different UEs ability was shown in following table 1.In the following table 1, Total number of soft channel bits representes total bit number of the pairing soft channel of UE ability rating; HARQ Number representes the number of HARQ treatment progress.

Combine embodiment that the present invention is done further description with reference to the accompanying drawings.
The peaked distribution method of a kind of available soft channel bit mainly comprises following content:
The processing of a, Node B side comprises:
One: Node B is provided with interim buffer memory size N TIR=T/N, wherein, T is the total bit number of soft channel of UE; N is that Node B is the quantity of the HARQ treatment progress of UE configuration, and N>=1; N TIRRepresent interim buffer memory size.
Two: confirm in N the HARQ treatment progress the available soft channel bit maximum N of each HARQ treatment progress IR
Here, N IRIn=predefined the enumerated value with NTIR near and be not more than the value of NTIR.
Three: it is the N that it distributed that Node B is notified UE through the mode of implicit expression IR
Here, carry out said notice with the mode of implicit expression and be meant: Node B is that the quantity of the HARQ treatment progress of UE configuration is notified to radio network controller with Node B only in the NBAP signaling, is not the N that UE distributed with Node B directly IRNotice is given radio network controller.
The processing of b, UE side comprises:
One: UE receives the N of Node B for its distribution IRMode be the mode of implicit expression.
Two: UE is provided with interim buffer memory size N TIR=T/N, wherein, T is the total bit number of soft channel of user equipment (UE); N is that Node B is the quantity of the HARQ treatment progress of UE configuration, and N>=1; N TIRRepresent interim buffer memory size.
Three, UE confirms in N the HARQ treatment progress, the available soft channel bit maximum N of each HARQ treatment progress IRIn=predefined the enumerated value with N TIRNear and be not more than N TIRValue.
In HSDPA, the N of each HARQ treatment progress IRBy the Node B decision, Node B is with the quantity N notice radio network controller of each HARQ treatment progress, and then, radio network controller is with the quantity N notice UE of each HARQ treatment progress.
Further, Node B notifies N to after the radio network controller, and radio network controller notifies N to UE.Through this process, can guarantee the consistency of Node B and the N of UE place, it is chaotic to prevent that channel bit position and logic implication from taking place.
Further, Node B is notified N to radio network controller through signaling, and wherein, signaling comprises: Radio Link is set up response message, wireless link reconfigured ready message or wireless link reconfigured response message.Node B is notified N through existing signaling to UE, implements fairly simple.
Further, Node B is notified N to radio network controller and comprised: Node B notifies N to floating radio network controller, and floating radio network controller notifies N to service wireless network controller.Radio network controller is notified N to UE and comprised: service wireless network controller notifies N to UE.Because there is the Iur mouth, the situation that also promptly can exist two RNC to link to each other, one of them RNC does Serving RNC, and a RNC does Drift Radio Network Controller, and then Node B is with N 1... N NNotify service wireless network controller through floating radio network controller, notify to UE by service wireless network controller again.
Further, radio network controller is notified N to UE through signaling, and wherein, signaling comprises: RRC link establishment message, radio bearer are set up message, radio bearer reconfiguration message, transmission channel reconfiguration message or cell update acknowledge message.Radio network controller is notified N through existing signaling to UE, implements fairly simple.
Further, Node B is confirmed T in the following manner: Node B is obtained the ability rating of UE; Node B is confirmed T according to ability rating.Through this mode, as long as Node B is known the ability rating of UE, can obtain the corresponding T value of this UE through mode such as table look-up, reduced the signaling consumption of reciprocal process.
Here, contrast the present invention and prior art can be known: in the prior art, under the situation of carrying out implicit assignment, because unpromising each the HARQ treatment progress of Node B distributes the reasonably available soft channel bit maximum N in the virtual incremental redundancy buffer memory IR, therefore, do not having N IROn the basis of limiting as the upper limit, possibly cause buffer memory to overflow or the buffer memory utilance low.And among the present invention, not only confirmed the available soft channel bit maximum N of each the HARQ treatment progress in N the HARQ treatment progress IR, and to N IRBe set to: in the enumerated value with average N TIRNear and be not more than N TIRValue, the benefit of doing like this is: on the one hand, can guarantee buffer memory total amount (that is N, that distributes IR* N) be no more than the total bit number T of soft channel of UE, prevented effectively to overflow; On the other hand, consider cache size that each HARQ treatment progress possibly take is from probability to equate, therefore, for each HARQ treatment progress distributes the N of identical size IRValue, realized N IRReasonable distribution, thereby improved the buffer memory utilance.In addition, distribute the N of identical size for each HARQ treatment progress IRValue, when radio network controller was notified this N, the signaling consumption that needs was less in Node B.
