This step can be carried out in execution of step 103 backs, in the time of also can working as the adjustment cycle arrival of the threshold value that retransmits reserved resource, according to the utilization of resources situation in this adjustment cycle, utilize the adjustment criterion need to judge whether to adjust, when having adjusted is when retransmitting the threshold value of reserved resource, then to enter into next adjustment cycle.
In this step, when adjusting the threshold value that retransmits reserved resource, judge that at first the threshold value of the re-transmission reserved resource that sets in advance is excessive or too small, thereby adjust the threshold value that retransmits reserved resource targetedly.And can judge that the threshold value of the re-transmission reserved resource that sets in advance is excessive or too small by following four kinds of methods in an embodiment of the present invention.
Method one, with initial transmission in the sub-district with to retransmit the actual resource statistics that takies be that standard is adjusted into the re-transmission reserved resource, can adopt following method of adjustment in an embodiment:
If in time T, satisfy
Then improve up for retransmitting pre-resource threshold value R
U_retra_threshold, for example can bring up to for retransmitting the reserved resource threshold value up
If in time T, satisfy
Then reduce up for retransmitting reserved resource threshold value R
U_retra_threshold, for example can be reduced to for retransmitting the reserved resource threshold value up
If above-mentioned two conditions do not satisfy, then do not need to adjust up for retransmitting the threshold value of reserved resource.
In above-mentioned method of adjustment, N
U_retrasmissionBe illustrated in the PRB number of uplink retransmission data occupancy in the field, what get here is the smooth value that each field uplink retransmission takies the PRB number in the time T; N
U_initialThe PRB number of representing up initial transmission data occupancy in the field, what also get is the smooth value that the up initial transmission of each field takies the PRB number in the time T;
TH is up for retransmitting the reserved resource threshold value, and this threshold value can be selected according to the actual conditions at scene.
The identical method of descending in an embodiment of the present invention and up employing judges that therefore descending determination methods is just no longer applied at this and stated.
Method two, by base station real-time statistics cell uplink and downlink resource utilance, and with on the sub-district/the downlink resource utilance is on standard is adjusted/descending serve as the threshold value of re-transmission reserved resource.
This method of adjustment is, when if the local resource utilance of satisfied statistics is lower than the threshold value that sets in advance, and the professional number that excludes inadequately because of resource is greater than the threshold value that excludes professional number that sets in advance, it is too much then can be indicated as the re-transmission reserved resource, passes the threshold value of reserved resource thereby can turn down to attach most importance to.If do not satisfy above-mentioned two conditions, then can adjust, above-mentionedly set in advance the process of threshold value that refusal connects business datum, and judge that the professional number that excludes all is a prior art with the process of this threshold value, this no longer deposited stating.
Method three, above/as descendingly not satisfy logic channel number that throughput requires and be on standard is adjusted/descending for retransmitting reserved resource.
This method of adjustment is: if do not satisfy logic channel number that throughput requires greater than set in advance do not satisfy the threshold value of the logic channel number that throughput requires the time, then think and admitted too much user, the threshold value of the re-transmission reserved resource that sets in advance is little, thereby should improve the threshold value that retransmits reserved resource, the threshold value and the deterministic process of the above-mentioned logic channel number that does not satisfy the throughput requirement that sets in advance all are prior aries, no longer apply at this and state.
The logic channel number that throughput requires is meant that each logic channel all has the throughput requirement according to the QoS of business, when the user admission success, but must can not satisfy this throughput requirement less than scheduling.When the logic channel number that does not satisfy the throughput requirement was many, too much user had been admitted in expression at present.
Method four, with on the sub-district/descending average repeat time is on standard is adjusted/descending serve as the re-transmission reserved resource.
Just, on the sub-district/descending average repeat time increases or reduce, then can improve accordingly or/reduction on/threshold value of descending re-transmission reserved resource.
This method of adjustment is: be chronomere with the time T, in the time must differing from greater than threshold value 1 between the average repeat time value of adding up in number of retransmissions value of adding up in this time T and the last time T, then improve the threshold value that retransmits reserved resource;
When the average repeat time value of adding up in average repeat time value-Ben time T of adding up in the last time T〉during threshold value 2, then reduce the threshold value that retransmits reserved resource;
When above-mentioned two conditions do not satisfy, do not adjust.
The sub-district average repeat time refers in the sub-district mean value of the number of retransmissions of all users' bags, promptly adds up the number of retransmissions of each bag, averages, if do not retransmit then number of retransmissions is 0 again.
The identical method of descending in an embodiment of the present invention and up employing judges that therefore descending determination methods is just no longer applied at this and stated.
The threshold value of judging the re-transmission reserved resource that sets in advance by four kinds of methods in the step 104 be excessive or too small after, then can adjust according to improving and reduce the threshold value that retransmits reserved resource respectively, this method of adjustment is as follows:
In the method one of step 104, adjust if judge up the needs, then can directly threshold value be adjusted to
Adjust if judge descending the needs, then can adjust to
In other three kinds of methods of step 104, can adjust a step-length according to judged result.For example according to method two, judgement need be turned down threshold value, then adjusts a step-length downwards.The size of step-length also needs to determine according to emulation.
By said method embodiment as can be known, this method is admitted the control gate limit value by being provided with, thereby for retransmitting reserved resource, make the resource that the possible re-transmission of not needs assessment takies when the newly-increased resource of assessment, avoided when admitting control, causing the problem of communication system overload effectively.
