Illustratively, Fig. 3 B is a schematic diagram of the ACK information that base station is sent to user equipment in the embodiment of the present application. Assuming that totally 20 UE, ID are respectively 1~20.Mark information is " 00 01 11 01 00 00 00 00 00 00 00 01 00 01 00 00 00 00 00 00".After UE receives the ACK information of network equipment transmission, where searching oneself in ACK information The x of positionnWhether 01 is equal to determine whether needing to retransmit.Wherein, " 00 " and " 11 " instruction user equipment can be used non-only The CTU enjoyed sends uplink information, and " 01 " instruction user equipment sends uplink information using the CTU exclusively enjoyed, specifically refers to Fig. 3 B It is shown.
When ACK information is broadcast message, each UE does not just know that oneself whether need to retransmit, currently it is also known that needs in all UE The corresponding position in ACK information the UE to be retransmitted.01 UE is marked as in ACK information by the sequence in ACK information sequence It has successively been assigned to the CTU exclusively enjoyed, and other UE are then sequentially allocated in order to remaining CTU.Shown in Fig. 3 B In, in certain transmission time slot, UE2 is collided with UE12, therefore they can be assigned to the CTU exclusively enjoyed. UE4 needs to retransmit due to demodulation failure, and UE14 has then been also indicated as 01 due to sharing the same CTU with UE4, thus It has been also distributed to the CTU exclusively enjoyed.Fig. 3 C is the flow diagram exempted from scheduling mechanism in the embodiment of the present application and transmit uplink information.
In the embodiment of the present application, a CTU is monopolized when retransmitting due to retransmitting UE, touch again when avoiding re-transmission The possibility hit.UE causes the case where retransmitting only possible generation primary due to collision, reduces unnecessary re-transmission.From entirety From the point of view of collision probability, the embodiment of the present application obtains consistency conclusion in terms of theoretical calculation with experiment simulation two, it was demonstrated that This patent mapping scheme reduces the collision probability of system, to reduce power consumption.Further, due to retransmission mechanism without etc. To back off time, smaller average delay is realized.
It should be noted that in addition to Sparse Code multiple access technique, also available to other multiple access technique fields.Example Such as PDMA, MUSA other can realize the multiple access technique for exempting from scheduling mechanism.By the CTU concept in this programme change into PDMA, Corresponding resource concept in MUSA, and resource is exclusively enjoyed to there is the UE for retransmitting and needing to distribute.
Fig. 3 D is traditional mapping schemes based on fixed window avoidance mechanism in the embodiment of the present application, is based on exponential backoff machine Collide the statistical chart of number in the traditional mapping schemes of system and the mapping scheme of the application.In shown in Fig. 3 D, Ke Yifa Existing tradition mapping method is there are data that are more secondary or colliding more than two times, and the data of technical scheme are to mostly occurring Primary collision, the whole number to collide are relatively low.
The collision probability formula of the collision probability and the application that derive prior art can prove that the application is implemented Example has a clear superiority from mathematical probabilities angle.Although if when the quantity of UE is excessive relative to CTU quantity under original state The UE that (i.e. CTU is shared by excessive UE) does not need largely to retransmit has been marked as 01 and has enjoyed the chance for exclusively enjoying CTU, meeting Cause certain wasting of resources.But theoretical formula is derived with the collision probability of simulation results show the application mapping scheme still Advantage is had more than traditional scheme.
It can carry out theory deduction and emulation experiment below to illustrate that the application has lower collision probability.It needs to illustrate , some data proposed in explanation below are only a kind of example, do not constitute the limit to the application protection scope It is fixed.Fig. 3 E is that UE collides the relation schematic diagram of UE par in probability and each CTU in the embodiment of the present application.Fig. 3 F The schematic diagram of probability is reached for collide probability and data of UE in the embodiment of the present application.It wherein, is this in Fig. 3 E and Fig. 3 F Apply for technical solution compared with traditional mapping ruler, traditional mapping ruler may include that fixed window avoidance mechanism is (existing again Scheme 1) and exponential backoff mechanism (existing scheme 2).The collision that Fig. 3 G is reduced by the technical solution in the embodiment of the present application is general The relation schematic diagram of rate and corresponding UE par in data arrival rate and each CTU.
It is assumed that one is exempted from dispatching uplink communication network comprising N number of competition the competition-based of transmission unit (CTU).Each The par for the UE being assigned in CTU is n, therefore, a shared N × n UE in system.NmExpression is assigned to m UE's The quantity of CTU, p indicate the average uplink data arrival rate of each UE, due to exempting from scheduling, stand once upstream data reaches UE It is sent to base station, without a series of handshake operations, so p, that is, upstream data sending probability.It is also possible to by p It is considered as the measurement of communication system traffic busy extent, the quantity of UE is enlivened in the UE of the shared CTU of k expression.Obviously, as k >=2, Two or more user equipmenies send upstream data in same competition transmission unit in this CTU, that is, are collided.
The embodiment of the present application can build the corresponding probability of any active ues quantity in a CTU using bi-distribution Mould.And in order to simplify problem optimization target, it is assumed that the upstream data one for the UE not collided surely by BS receive and at Function demodulation, i.e., re-transmission in need the reason of only be from collision between user equipment.So, n user equipment is assigned CTU in, have k user equipment while sending the probability of upstream data and follow bi-distribution and can be expressed as
Then, the probability for having collision to occur in CTU is i.e. are as follows:
In the embodiment of the present application, by b (k；N, p) use pn,k,pSymbol replaces, and respectively by UE in traditional resource impact Collision probability p under the resource impact scheme that scheme and the application proposeconWith pproIt indicates.Next both will be provided to reflect The collision probability derivation process under scheme is penetrated, the superior of the resource impact scheme that the application is proposed is proved finally by comparing Property.
It 1, can will be all in a communication process when calculating the UE collision probability under existing resource impact scheme UE is divided into two pieces to discuss --- and it include the UE for not including in the UE and CTU of re-transmission demand and having re-transmission demand in CTU.
(1) include in CTU re-transmission demand UE.
Firstly, the UE quantity to collide in a CTU are as follows:
Because CTU quantity is N, in all UE, the UE quantity that needs to retransmit are as follows:
When a collision occurs, it needs to reattempt re-transmission using avoidance mechanism.Ideally, it is had occurred in the same CTU This several UE of collision should be different from each other in randomly selected back off time, and otherwise, the UE to collide still can be in weight It is collided again when biography.In following probability calculation, moving back at random for the user equipment collided under same CTU selection is not considered for the time being Keep away time identical probability.It will prove below, even if this probability to be included in the collision probability of existing scheme, this patent is touched It hits probability and still is below existing scheme.Therefore, in the case that the random-backoff time for considering each re-transmission UE selection is to be staggered, These retransmit the UE quantity to collide again in UE are as follows:
Above-mentioned formula 6 it can be concluded that be because only need consider retransmit UE where CTU in, in addition to re-transmission that UE with Outside, one or more UE has the case where upstream data arrival in remaining UE.
(2) UE for having re-transmission demand is not included in CTU.
Firstly, calculating the CTU probability for not including in CTU and having the UE of re-transmission demand:
Since the UE in this kind of CTU is first transmission upstream data, it is only necessary to can be sent out inside each CTU with simply calculating The UE quantity of raw collision, which is multiplied, obtains the UE quantity that total meeting of this part collides:
Therefore, under existing resource impact scheme, the collision probability of UE are as follows:
2, when calculating the UE collision probability under resource impact scheme proposed in this paper, all UE can also be divided into two Block discusses --- exclusively enjoy the UE of the UE and shared CTU of CTU.
(1) UE of CTU is exclusively enjoyed.
Since exemplified scheme is to analyze it to there is re-transmission UE to provide characteristic as the CTU that one exclusively enjoys When collision probability, consider to calculate total re-transmission UE quantity first, when BS demodulates failure to a certain uplink information, just can not learn The UE ID of the information is sent, therefore, all UE in CTU used in the signal of demodulation failure are marked as 01 by BS, that is, work as CTU Inside there is part UE to collide, then all UE will obtain exclusively enjoying CTU in CTU.Therefore total UE for having obtained exclusively enjoying CTU Quantity are as follows:
(2) UE of CTU is shared.
It can be calculated by formula 10, it is remaining for shared CTU number of resources are as follows:
Nmulti=N-Nsingle(formula 11)
This is to be shared for upstream data by non-zero 1 remaining UE, and UE is spread evenly across this NmultiIn a CTU.By In it is this be averagely it is opposite because the UE quantity of shared CTU may not necessarily be shared CTU quantity and divide exactly, in a part of CTU The UE quantity being assigned to can be 1 more than other CTU, it is assumed that the UE quantity being assigned in shared CTU has k and two kinds of k+1, needs This two parts CTU is individually considered, the UE number of its collision is calculated.Here, N can be solved with simultaneous one group of equationkWith Nk+1 Number:
Nk+Nk+1=Nmulti(formula 12)
It need to obtain NkWith Nk+1Expression formula about n, p.But in above-mentioned equation group, k is by sharing the UE quantity of CTU divided by altogether The quantity for enjoying the CTU of property is rounded downwards gained, is not determining numerical value, thus equation can not solve.If a upper time slot touches Hit that situation is slighter, then the CTU monopolized is less, and the degree of crowding of UE not will increase much in shared CTU, i.e. the number of a It is worth smaller；Conversely, monopolized a large amount of CTU if last round of crash behavior is extremely serious, only remaining a small amount of CTU is distributed to UE without re-transmission shares, then the numerical value of a is larger.Since under normal circumstances, the collision probability of system is no more than 6%.Therefore, A can be considered as 0, i.e. k=n in calculating shared CTU when the distribution situation of number of users by sum up situation.
This part UE due to exclusively enjoying CTU will not necessarily collide, and only need to consider in the embodiment of the present application shared This NmultiThe UE quantity to collide in a CTU inside collides for the CTU shared by k user equipment UE quantity are as follows:
For the CTU shared by k+1 user equipment, the UE quantity that inside collides are as follows:
Therefore, under existing resource impact scheme, the collision probability of UE are as follows:
From formula 9 and formula 17 it is found that having been obtained under existing resource impact scheme and the mentioned mapping scheme of author Collision probability.Therefore, the difference of the two probability are as follows:
It can also attempt to do formula 18 simplification mathematically, due to:
Therefore, formula 18 can be simplified expression are as follows:
Pdiff=(1-qn-1)(1-qn-1+(n-1)p)+(1-qn-npqn-1)(n2-1)(qn-qn-1)
(formula 20)
Wherein, q=1-p.By in Fig. 3 G it can be seen that p=0, when n=2, pdiff=0, and when p >=0, n >=2, function list It adjusts and is incremented by, therefore, the probability that the technical solution in the embodiment of the present application collides when UE sends uplink information is less than Technical solution provided by the prior art.
