Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the invention, rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that obtained, belong to the scope of protection of the invention.
Embodiment one
The embodiment of the present invention provides a kind of SR resource reuse methods, to reduce the expense of this part of PUCCH.
The basic ideas of the method for the invention are：ENB is identified to the user for being accessed, for portfolio ratio
The not high user of relatively low or liveness, system carries out them to be combined into one group, and user will be using completely in group
Consistent SR resources.System will realize certain adaptation mechanism for the user that SR is reused in user's group, wrap
Include received and which user specifically dispatch after SR.Because in identical SR resources, the symbol content of SR is complete
Consistent, therefore the user in group shares same SR resources, is will not to be formed to interfere, and is only equal to same
The situation of the multipath of one signal, unique problem be eNB None- identifieds SR be on earth user's group it is concrete which
Individual user produces, but can be solution by rational adaptation.Therefore by the present invention, can't be obvious
The process of the quality of reduction business, mainly eNB sides slightly increases complexity.But SR has suitably been saved on the whole
Partial PUCCH format1 resources, in addition, comparing original because SR is resource-constrained to lead to not distribution
The user of SR resources, this programme reduces the frequently random access procedure of these users and processes, and is equal to drop
The load that low Stochastic accessing is processed.
As shown in figure 1, the flow chart of the method provided for the embodiment of the present invention one, comprises the steps：
Step S101, by the selection strategy of setting, in the accessed user of current area user is selected, and is obtained
User's group；
Step S102, is identical SR resource by the user configuring in the user's group；
Step S103, when the SR using the SR resource reportings is received, according to the adaptation strategies of setting,
User, and the user's distribution ascending resource to select are selected in the user's group.That is, base station side
By the adaptation strategies for setting, suitable user is selected as the transmission source of SR, only response is considered as SR
The user of transmission source.
Illustrated based on above-mentioned principle, several concrete and preferred embodiments are given below, to refine and optimize
The function of the method for the invention, so that the enforcement of the present invention program is more convenient, accurately.It should be noted that
In the case where not conflicting, following feature can be combined mutually.
In the embodiment of the present invention, the selection strategy set in step S101 includes following one or more selections
Condition：User configured SR cycles in user's group are consistent, the service priority of user in user's group is low,
And the traffic demand of the user in user's group is low.Certainly, those skilled in the art can with according to oneself
Demand is increased or is deleted, and the present embodiment does not do unique restriction to the species and number of alternative condition.
It is determined that after alternative condition, certain rule, formation selection strategy can be configured.The rule for wherein configuring
It is exactly then, with alternative condition as parameter, to form selection algorithm.For example may refer to show system when user selects,
Preferentially with which condition as the most important condition, if in the case of the most important condition is ungratified, to be carried out with which condition
Select etc..
Further, it is identical SR resource by the user configuring in the user's group in the embodiment of the present invention,
Specifically include：Choose a user in the user's group, in this user's group except choosing with outdoor
Other users initiate RRC connections and match somebody with somebody flow process again, by the SR resource distributions of its SR resource and the user for choosing
Into consistent.
Further, in the embodiment of the present invention, the adaptation strategies in step S103 are including but not limited to：
Strategy one：Judge that the user's group user for configuring the SR resources has reported the SR, so, select
All users of the user's group, are responded；
Strategy two：The mode of a user is selected according to a SR cycle, is replaced in the user's group interior circulation
Select user；I.e.：Assume there are two users in user's group, the SR resources that the current SR cycles receive are recognized
To be the user 1 in user's group, then the next one SR cycles to the SR resource certainty that arrives of reception
It is the user 2 in user's group, the user in user's group is based entirely on the principle of justice.
Strategy three：When the observation cycle of setting starts, according to preset priority level initializing mode, institute is set
The priority of each user in user's group is stated, and in the observation cycle of setting, according to User Priority order,
In the way of a SR cycle selectes a user, in the user's group interior circulation alternate selection user；It is described
Observation cycle is the integral multiple in N number of SR cycles, and the N is the number of users in user's group.Further,
Equivalent to a kind of optimization of strategy two, i.e., system is firstly evaluated out in user's group the strategy, and which user sends out SR
Probability higher (which user uplink scheduling can not be obtained the longer time based on, and be used based on which
Family uplink service flow is more high, and the assessment this patent does not do further restriction), accordingly, for what is received
SR resources, are considered as the reporting of user of the more high probability first.Illustrate, it is assumed that in user's group
User is two, is respectively user 1 and user 2, and system side can arrange the sight in 4 times of SR cycle
The cycle is examined, for the SR most initially received in the observation cycle, system is first considered that the SR is that high SR is general
What user's (high priority) of rate reported, such as high SR probability user is user 1, and in the observation cycle
The SR resources for inside hereafter receiving, will be based entirely on the fairness doctrine, be followed successively by user 2, user 1, user
2 this alternate selection modes.The strategy compares strategy two, has higher probability to match actual SR
User, reduces because SR resources judge the wasting of resources for bringing by accident.
The user selected according to above-mentioned adaptation strategies may be not necessarily the user that actually have sent SR, i.e. we
Case be likely to occur " SR obscure " problem, it is specific that we divide 2 class situations to illustrate：
A, to there is two users in user's group as a example by, it is assumed that 2 users have sent SR simultaneously, and system is judged to
Pairing user 1 sends out SR, has only done uplink scheduling to user 1, and now user 2 is because of being dispatched,
Can continue to report SR in the SR resources of next cycle, even now strategy two or strategy three, hands over
The method that alternative is selected, then be judged to that matching user 2 sends out SR certainly, and carries out further responsive to generation
Affect, that is, the SR for matching user 1 is timely responded to, pairing user 2 has retransmitted 1 SR and just met with a response,
For user 2, time delay increased, but because pairing criterion has paid the utmost attention to these low business demands
User, therefore the time delay loss does not result in problem substantially perceptually；
B, pairing user 1 have sent SR, and system is judged to that matching user 2 sends out, now system can to
Further uplink scheduling is done at family 2, and this action may be unnecessary, but will not be problematic, because obtaining up
User 2 after scheduling has data really if up buffering area, then normal consistency, if user 2 is up
Buffering area is without the data that can be sent out, then can be embodied on BSR, and according to the instruction of BSR, system will not be after
The continuous ascending resource for dispatching the user, the impact maximum for thus resulting in also be only waste 1 time it is meaningless
Uplink scheduling.And the user 1 of SR is actually sent because without scheduling, can provide in the SR of next cycle
SR is transmitted on source, now if strategy two or strategy three, the method for alternate selection is then sentenced certainly
It is set to pairing user 1 and sends out SR, and carries out further responsive to the impact of generation is matched user 1 and retransmitted
1 SR just meets with a response, and for user 1, time delay increased, but because pairing criterion is preferentially examined
Consider the user of these low business demands, therefore the time delay loss does not result in problem substantially perceptually；
Generally, confounding issues can bring the waste of uplink scheduling resource, but itself sends the frequency of SR simultaneously
Not high, it is less to thus result in the probability obscured, particularly strategy three, can effectively reduce the possibility obscured.From
Resource view, for the ascending resource of dynamically distributes wastes very limited, but for the SR resources of static configuration
For, the present invention has its positive effect, alleviates the resource bottleneck of SR, also mitigates because not having
The Stochastic accessing repeatedly that SR resource allocations are caused.
Further, it is preferred to select two in order to reduce the time delay that SR mictiums that may be present come as far as possible
User forms a user's group.
Further, in the embodiment of the present invention, base station needs restriction pairing user SR+ occur in descending scheduling
The situation of ACK/NACK, when dispatching any one user in user's group, judges this time whether scheduling can go out
The possibility of existing SR+HARQ ACKNACK, if it has, then abandoning this descending scheduling, is deferred to next
Secondary descending scheduling.
Further, in the embodiment of the present invention, when selected user no longer meets the selection of the selection strategy
During condition, the user is rejected from the user's group, and SR resources are reconfigured for the user.For example use
The flow liveness of certain user in the group of family is improved, service priority is improved etc., then system can be user's weight
New distribution SR resources.
In summary, the method for the invention rationally reduces the demand of SR resources by SR resource reuses,
Mitigate the phenomenon because of resource bottleneck caused by SR resources.
Embodiment two
The embodiment of the present invention provides a kind of SR resource reuse methods, and it passes through to disclose more ins and outs, right
The methods described of embodiment one is described in detail.Two users are set in the present embodiment as a user's group.
As shown in Fig. 2 SR resource reuse methods comprise the steps described in the present embodiment：
Step S201, new UE is successfully accessed；
Step S202, judges whether current area meets the condition for enabling " SR resource reuse schemes ", if
It is, then into step S204, if it is not, then into step S203；
Specifically, " cell enables the number of users door of SR resource duplicate allocations to one threshold value of eNB systems setting
Limit ", if current connected state number of users is less than the thresholding, SR resource allocations use old process；If
Current connected state number of users is more than or equal to the thresholding, judges that satisfaction enables the bar of " SR resource reuse schemes "
Part, enables Optimizing Flow of the present invention.
That is, system is according to current connected state number of users (can reflect SR resource accounting situations), really
Whether settled front SR resources have reached the degree of fast exhaustion, if it is determined that being yes, then now system needs to enable
The function of SR resources recycling.
Step S203, currently prioritization scheme of the present invention is not enabled, by original flow implementation；
Step S204, prioritization scheme of the present invention is enabled, select 2 suitable users to be matched；
Wherein, pairing user is selected to need the condition for meeting to include：The SR that 2 UE are configured before this is all
Phase is consistent, and other conditions can also include：Business scenario of the user in low rate, service priority compares
Low, system can select 2 minimum user priorities of priority and be matched, and certainly this is not unique judgement
Criterion.For the UE of the low demand of business, SR reuses the worst brought to be affected mainly equivalent to extension
In the original SR cycles so that the service delay of pairing UE is increased, itself is relatively low due to service priority,
Therefore the loss to Qos does not have very seriously, can be acceptance；In addition, from another point of view, persistently adjust
The probability that the user of degree sends SR is lower, may be also more suitable for this kind of UE reuse SR.But it is concrete
Select which kind of decision criteria present invention does not do specific restriction.
Need to produce how many couples of pairing users as system, need to meet a criterion：Produce 1 pair of pairing
After user, system reexamines current SR resource accountings, if being less than risk thresholding, does not continue to detection
New pairing user, if still above risk thresholding, continues to detect new pairing user.System can put
One detection cycle in top, without frequently initiating detection.
Step S205, system initiates RRC Connection Reconfiguration flow processs, by one of use
The SR resource reconfigurations Cheng Yuqi pairing UE at family is completely the same, and the original SR resources of the user are discharged can
For new user；
Step S206, system receives the SR that pairing UE is reported, according to the adaptation strategies of setting, in pairing
User in select user for its distribution ascending resource.That is, user is selected according to adaptation strategies, it is believed that thereon
SR is reported, has been its distribution ascending resource.
Wherein, adaptation strategies are including but not limited to：
Strategy one：Think that 2 UE have reported SR；
Strategy two：Think that what is now reported is the user A in pairing user, and next one SR TTI are then recognized
To be to match the user B in user, successively repeatedly.It is configuration in the actual SR cycles that strategy two is equal to user
2 times, between 2 users of pairing the Offset of SR resources be 1 configuration SR periodic quantities.
Strategy three：Belong to the optimization to strategy two, i.e., by the history dispatch situation and money of pairing user A, B
Which user source conditions of demand etc., in advance anticipation more likely initiates SR, then to subsequently received SR
Preferential that user for judging to be the high likelihood of anticipation before this, then hereafter still according in strategy two successively
Order repeatedly is carried out, and detail is elaborated in embodiment one.Illustrate, i.e., system side can
To arrange the observation cycle in 4 times of SR cycles, for the SR most initially received in the observation cycle,
System is first considered that the SR is the reporting of user of high SR probability, and such as high SR probability user is pairing
User A, and the SR resources hereafter received within the observation cycle, will be based entirely on the fairness doctrine, be followed successively by
This alternate selection mode of user B, user A, user B.The strategy compares strategy two, there is higher general
Rate can match actual SR user, reduce because SR resources judge the wasting of resources for bringing by accident.Need
Illustrate, high SR probability user be not once assess it is whole effectively, assess high SR probability user it is effective when
Between i.e. one observation cycle time, the high SR probability user in next observation cycle will reappraise.
Which kind of specifically it is not particularly limited using the tactful embodiment of the present invention.
Have selected after user according to above-mentioned adaptation strategies, even user selects mistake, as SR is retransmitted
Response can be obtained in next SR TTI.And for the user of errored response, it is also possible to according to user feedback
BSR (Buffer Status Report, buffer status report) can know in time.
In addition, system to user when descending scheduling is carried out, need to do some optimizations to evade the 2 of pairing
The presumable SR+ACKNACK scenes of individual UE bring the problem of ambiguity.Fairly simple method is to adjust
During any one user of degree pairing user, judge this time whether scheduling occurs SR and HARQ
The possibility of ACK/NACK simultaneous transmissions, if it has, this descending scheduling is then abandoned, under being deferred to next time
Row scheduling.Avoid SR TTIs of the corresponding HARQ ACKNACK of scheduling user in pairing user
On.
Step S207, system need periodically to judge whether the user for having matched current area also meets pairing
Require, if can also meet, into step S208, if can not continue pairing, enter step
Rapid S209；
Step S208, first wife continue to keep pairing state to user；
Step S209, for those have been unsatisfactory for the user of matching request, system will be redistributed newly
SR resources give these users, it is to avoid these users continue to occur the situation that SR repeats.
In summary, the present embodiment methods described is not related to the modification of message, and only eNodeB sides introduce some and repair
Change, UE sides implement simple, conveniently connect without any modification.
