Embodiment 3
Resource allocation methods when present embodiment provides a kind of ascending control information multiplexing; In up resource allocation; According to MLP (MAC Logical Channel Priority, MAC logical control channel priority) UE is carried out Resources allocation, scheduling and distribution RB carry out according to MLP is ascending; When supposing this module of input, obtained the RB and the initial MCS value of sub-distribution just.
The embodiment of the invention can be applied in the LTE system; For example; LTE system shown in Figure 3; Fig. 4 is the another kind of flow chart of the resource allocation methods when multiplexing according to the ascending control information of the embodiment of the invention, and the flow process of this embodiment specifically realizes through base station side, and the RB number of supposing to distribute on each MLP UE is RB Last, mainly may further comprise the steps:
S401: judge whether UCI flag (this value initialization is 0) equals zero, if equal zero, then carry out the allocation process of ascending control information when multiplexing,, then withdraw from this flow process if be not 0.The consideration of this step here mainly is for the less situation of multiplexing ascending control information, if when first MLP, code check is just not high, then can judge when second MLP, and code check is not high yet, therefore need not advance the flow process of RB and MCS value adjustment.
S402: judge whether current MLP is first MLP of this UE, if, execution in step S403, if not, execution in step S409.
In the present embodiment, first MLP and second MLP of UE treated with a certain discrimination, carried out the expansion of RB as first MLP; When second MLP,, then only need carry out normal RB allocation flow if need not carry out the expansion of RB; Just can reach the code check requirement of multiplexing ascending control information, simultaneously, when second MLP; Also need carry out rollback operation to the RB that expands, the purpose of doing like this is to let the RB of rollback that other UE can be used, wherein; Rollback operation can be included in to be judged under the situation that the code check reach multiplexing ascending control information requires, and discharges all RB that expanded, and perhaps only discharges a part of RB that expands.
S403: according to the RB of original allocation Last, and initial MCS value, calculate code check R professional when no up control information is multiplexing under this configuration MCS, and calculate the upper limit R of no up control information code check when multiplexing, wherein R=R MCS+ (R MCS+1-R MCS)/A, the limit bit rate (wherein the value of A can be the arbitrary number greater than 1) for satisfying service feature calculates under the current MCS value simultaneously, professional code check R ' during multiplexing CQI/PMI/RI.
S404: judge this moment during multiplexing CQI/PMI/RI professional code check R ' whether greater than limit bit rate R; At this moment; Judge whether that whether high Rule of judgment greater than limit bit rate be code check Rule of judgment behind the present multiplexing ascending control information, has only the high expansion that just needs consideration RB resource of code check this moment.
If code check R ' professional during multiplexing CQI/PMI/RI is greater than limit bit rate R, execution in step S405 then, if less than, then UCI_flag is set to 1, execution in step S408.
S405: after calculating multiplexing ascending control information, the RB that code check R ' need expand during greater than limit bit rate R counts RB UCI_RB, judge whether available RB simultaneously, if having, execution in step S406 is not if there is execution in step S407.
The RB that here need expand counts RB UCI_RBCalculation Method is: make RB UCI_RB=RB UCI_RB+ 1, wherein, RB UCI_RBInitial value be 0, whether the code check R ' of business judged R ' greater than R when the RB number that expands as required and the RB of original allocation counted limit bit rate R that sum and initial MCS value recomputate service feature and multiplexing ascending control information, as if greater than, then proceed RB UCI_RB=RB UCI_RB+ 1 operation is till code check R ' is smaller or equal to R.
Judging available RB, mainly is to judge (RB Most>=RB UCI_RB) & (RB Last+ RB UCI_RB≤RB Rest) whether set up RB wherein MostBe the RB number that maximum power can be supported, RB RestRB number for remaining maximum continuous.
S406: expand the RB number that distributes.
Expand the RB number that this MLP distributes to this UE, RB Last=RB Last+ RB UCI_RB, the RB number that the renewal maximum power can be supported and the continuous RB number of remaining maximum, RB Most=RB Most-RB UCI_RB, RB Rest=RB Rest-RB UCI_RB, and write down the RB that gives this UE and count RB UE=RB Last(RB UEInitialization value is 0) execution in step S408.
S407: reduce the MCS value of distributing.
At this moment, owing to can't expand RB, then can only reduce professional code check behind the multiplexing ascending control information through falling the MCS value, the method for adjustment MCS value is:
Make MCS value=MCS value-1, professional code check R ' when recomputating limit bit rate R and the multiplexing ascending control information of service feature judges that whether R ' is greater than R; If R ', then proceeds MCS value=MCS value-1 operation greater than R, till code check R ' is smaller or equal to R; It should be noted that here if MCS value=0 o'clock, code check is still high; Then abandon the transfer of data of this UE, use to other UE the resource of this UE.
S408: output UCI_flag, RB UCI_RB, the RB that this MLP distributes counts RB LastAnd total RB that this UE distributes counts RB UE
S409: if current MLP is not first MLP of this UE, the RB that current this UE of then first calculating has distributed counts RB UE=RB UE+ RB Last, according to RB UEAnd initial MCS value, calculate code check R professional when no UCI is multiplexing under this configuration MCS, and calculate UCI professional limit bit rate R, wherein R=R when multiplexing MCS+ (R MCS+1-R MCS)/A, (value of A is seen step S403) calculates under the current MCS value simultaneously, professional code check R ' during multiplexing CQI/PMI/RI.
S410: judge whether to satisfy R＜R ', if do not satisfy, make UCI_flag=1, execution in step S411 is if satisfy execution in step S405.
S411: the rollback operation that carries out RB.The requirement that RB number that distribute this moment and initial MCS value have satisfied multiplexing ascending control information owing to ascending control information multiplexing introduced extra RB, need be carried out the rollback of RB, so that the use of follow-up UE.At this moment, if in second MLP, because this UE has distributed the RB resource again; Twice MLP goes up the RB resource of distributing and adds up, and behind the multiplexing uplink information, code check R ' is less than limit bit rate R; Whether the RB resource of distributing when considering ascending control information when code check was high when needed to consider first MLP this moment can carry out rollback, if code check R ' then carries out the rollback of RB still less than limit bit rate R behind the rollback; If code check R ' is more than or equal to limit bit rate R behind the rollback, rollback not then.The fallback mechanism of introducing RB mainly is in order to let the RB resource reach optimization, and then improves the throughput of sub-district.
Above-mentioned back off procedure specifically comprises: make RB UE_Temp=RB UE-Δ RB, Δ RB=1 ..., RB UCI_RB, according to RB UE_TempReach the MCS value, calculate and to dispose down, the code check R of business when no UCI is multiplexing MCS, and calculate the limit bit rate R that satisfies the service feature requirement, wherein R=R MCS+ (R MCS+1-R MCS)/A.Calculate under current RB number and the MCS value professional code check R ' during multiplexing CQI/PMI/RI simultaneously.Judge whether to satisfy R '＜R,, then make Δ RB=Δ RB+1, continue to calculate R and R ', the Δ RB value of correspondence when finding first a R '＜R not satisfy if satisfy.
More be newly assigned to the RB number of this UE, and RB UE=RB UE-Δ RB+1 considers the RB adjusted value RB when ascending control information is multiplexing UCI_RB=RB UCI_RBThe RB number that-Δ RB+1, this MLP give this UE is: RB Last=RB Last-Δ RB+1
Resource allocation methods when the ascending control information that present embodiment provides is multiplexing is applicable to that all carry out the multiplexing user of control information in the sub-district, is carrying out by MLP from low to high after the Resources allocation; Carry out the processing of ascending control information when multiplexing again, consider that uplink information controls the code check of traffic channel data when multiplexing, if code check is greater than limit bit rate; Then pay the utmost attention to the processing of expanding RB,, then consider to fall the MCS value if there is not available RB this moment; Till code check is smaller or equal to limit bit rate, simultaneously if UE Resources allocation all in two MLP, when second MLP; If code check is less than limit bit rate, then will consider the rollback operation of RB, when even two MLP resource sum of distributing lets the code check of Traffic Channel less than limit bit rate; The RB number that then increases during first MLP of rollback; Can optimal use RB like this, and then improve the system availability of RB, finally improve throughput.
In step 406 and 407, considered the mode of two kinds of multiplexing ascending control informations, if when available RB is arranged, then pay the utmost attention to the processing that increases RB, if during no available RB, then the processing of MCS value falls in consideration.
