In step S310, it is judged that unit 110 judges whether community is in busy condition.Judging unit 110
The information of itself can judge whether community is in busy condition from base station 100；Can also set from user
The information of standby 900 feedbacks judges whether community is in busy condition.
Refer to Fig. 4, it illustrates the thin portion flow chart of step S310 of Fig. 3 according to an embodiment.So
And, step S310 of Fig. 3 is not limited to the flow chart of Fig. 4.In step S311, it is judged that unit
110 resource block obtaining the multiple resource block (resource block, RB) in a period of time
Utilization rate (RB used ratio) UR and buffer status reporting value (buffer status of community
report)BSR.In one embodiment, time cycle e.g. 100 milliseconds.
In step S312, it is judged that unit 110 judges that whether resource block utilization rate UR is more than a utilization rate
Threshold values URT.Resource block utilization rate UR of resource block is the highest, represents that the busy degree of community is the highest.
Therefore judging unit 110 can be by resource block utilization rate UR of resource block and the utilization rate threshold values preset
URT compares, to judge whether community is in busy condition.If resource block utilization rate UR is more than
Utilization rate threshold values URT, then enter step S313；If resource block utilization rate UR is not more than utilization rate threshold values
URT, then enter step S315.
In step S313, it is judged that unit 110 judges that whether buffer status reporting value BSR is more than a report
Threshold values BSRT.Buffer status reporting value BSR is the highest, represents that the busy degree of community is the highest.Therefore judge single
Buffer status reporting value BSR can be compared by unit 110 with the reporting threshold BSRT preset, to judge
Go out whether community is in busy condition.If buffer status reporting value BSR is more than reporting threshold BSRT, then enter
Enter step S314；If buffer status reporting value BSR is not more than reporting threshold BSRT, then enter step S315.
In step S314, it is judged that unit 110 judges that community is in busy condition.In step S315,
Judging unit 110 judges that community is not at busy condition.Enforcement by step 310 described by above-mentioned Fig. 4

The judged result of any one of step S312 and step S313 is "No", i.e. enters step S315.
Then, in step S320 of Fig. 3, computing unit 120 calculates each according to the busy degree of community
Individual user equipment 900 uses a maximum restriction usage quantity MN of resource block.In this step, meter
Calculate unit 120 and calculate maximum factor M F according to following formula (1).Maximum factor M F is between 0～1.
Then, maximum restriction usage quantity MN is calculated further according to following formula (2).
MF=1-[FF*RU+ (1-FF) * NR] ... ... ... ... ... ... ... ... (1)
MN=MF*TN ... ... ... ... ... ... ... ... ... ... ... ... (2)
Immobilisation factor FF is for a configurable value, e.g. 0.25.Resource block utilization rate RU is more
Height, the interference produced that expresses possibility is the biggest, therefore maximum factor M F and the maximum usage quantity MN that limits must bear
It is relevant to resource block utilization rate RU.It addition, user's bit error rate of medium access control layer (MAC layer)
NR is the highest, represents that interference is the biggest, therefore maximum factor M F and the maximum usage quantity MN that limits must negative correlation
In user's bit error rate NR.
Then, in step S330, allocation unit 130 limits each user equipment 900 with maximum limit
Usage quantity MF processed uses resource block.When community is in busy condition, each user equipment 900
Only can use the maximum resource block limiting usage quantity MF.It is to say, each user equipment 900
No longer take too much resource block, and no longer easily and another community uses same resource block simultaneously,
Same resource block is all distributed to the most different user equipment reducing this community from another community
The situation of 900.Consequently, it is possible to relatively it can be avoided that produce tight between the user equipment 900 of multiple minizone
Heavily disturb.
