Namely the channel quality information that terminal to report measurement is arrived, and metrical information is reported, scheduling unit is according to measuring reported result, and according to certain criterion, UE is scheduling by simulation;

It should be understood that

In this step, similar with the dispatching method of 3GPPTS36.321 for the concrete UE method being scheduling, again repeat no more.

Current shared frequency spectrum has 10MHz, and assume 2 base stations of deployment under the system/operator of each frequency spectrum application unit place, name base station is numbered NodeB_1_1, NodeB_1_2, NodeB_2_1, NodeB_2_2, NodeB_3_1, NodeB_3_2, wherein NodeB_1_1 represents first base station of frequency spectrum application unit place system/operator subordinate, remaining explanation is similar, repeats no more. 30 users are had under each base station. Then this programme to implement flow process as follows:

Step 1: each frequency spectrum application unit reports spectrum requirement to frequency spectrum allocation units.

If meeting, then it is allocated according to the demand of each frequency spectrum application unit;

If being unsatisfactory for, then carry out the 3rd step.

Step 3: the frequency spectrum allocation units demand according to each frequency spectrum application unit, carries out the determination of frequency spectrum distribution reference cell size, and the usable spectrum having divides less frequency spectrum distribution reference cell. Two frequency spectrum application units respectively 5MHz and 10MHz needed for reporting, the frequency spectrum of the total 10MHz of frequency spectrum allocation units, then frequency spectrum distribution reference cell is 5MHz, and has two frequency spectrums distribution reference cells.

(1) administrative terminal is simulated scheduling by fund allocation within a fund family unit. Namely the channel quality information that terminal to report measurement is arrived, and metrical information is reported, scheduling unit is according to measuring reported result, and according to certain criterion, UE is scheduling by simulation;

(2) result of resource distribution after scheduling is recorded by scheduling unit, according to resource allocation result, is handling capacity by channel quality mapping, specifically as shown in table 7 and table 8;

Wherein, the mapping relations between channel quality with handling capacity are consistent with existing mapping thinking, namely select suitable MCS grade according to channel quality, and then determine TBS size, such that it is able to according to received signal to noise ratio, determine handling capacity with TBS size.

Throughput_1 = Σ_{i = PRB 1}^{PRBn} Throuthput_1_i + Σ_{i = PRB 1}^{PRBn} Throuthput_2_i,

Namely front n the handling capacity numerical value sum that front n the handling capacity numerical value of the 4th row of table 3 arranges with table 4 the 4th, the computational methods of Throughput_2 are similar, repeat no more. Wherein total throughout is the summation that each frequency spectrum distribution reference cell brings handling capacity.
