Embodiment one

Present embodiment provides a kind of resource regulating method, and present embodiment combines the foregoing description and preferred implementation wherein.

Step 1: earlier the sector is numbered, following 3 adjacent sectors in same base station are numbered 1,2,3 respectively according to the difference of its antenna main lobe direction; Can sort according to certain rule for the running time-frequency resource that terminal scheduling uses, suppose that all running time-frequency resources can dispatch the running time-frequency resource particle according to minimum and can be divided into N3 part, then number consecutively is 1,2 ... N1, N1+1 ... N2, N2+1 ... N3-1, N3.Then this resource is divided into 3 parts, is designated as F1, F2, F3 gives 3 sectors respectively, and is specific as follows:

For the sector that is numbered 1, running time-frequency resource particle 1, the set F1 that 2...N1 forms is considered as its low interference region, and this zone original position index is 1, and the final position index is N1, and remaining zone then is the high interference zone;

For the sector that is numbered 2, running time-frequency resource particle N1+1, the set F2 that N1+2...N2 forms is considered as its low interference region, and this zone original position index is N1+1, and the final position index is N2, and remaining zone then is the high interference zone;

For the sector that is numbered 3, running time-frequency resource particle N2+1, the set F3 that N2+2...N3 forms is considered as its low interference region, and this zone original position index is N2+1, and the final position index is N3, and remaining zone then is the high interference zone;

F1 wherein, F2, F3 resource collection size is identical, is made as M, the minimum time that unit distributes for scheduling.Then M is 1/3rd of total Gong a scheduling resource particle, that is to say, and parameter N 1, N2, N3 satisfies: N1=M; N2=2M; N3=3M.

That is: running time-frequency resource set F1 is the low interference region of sector 1, is the high interference zone of sector 2,3.Running time-frequency resource set F2 is the low interference region of sector 2, is the high interference zone of sector 1,3.Running time-frequency resource set F3 is the low interference region of sector 3, is the high interference zone of

sector

1,2.

Step 2: for time-frequency set F1, F2, F3 further is divided into two, respectively called after fixed area and on-fixed zone.Concrete: F1 is for sector 1 in the time-frequency set, the fixed area piece of F1 is its fixing low interference region, the on-fixed region unit of F1 is its revocable low interference region, and for sector 2 and sector 3, the fixed area piece of F1 is its fixedly high interference zone, and the on-fixed region unit of F1 is its revocable high interference zone.In like manner: F2 is for sector 2 in the time-frequency set, the fixed area piece of F2 is its fixing low interference region, the on-fixed region unit of F2 is its revocable low interference region, and for sector 1 and sector 3, the fixed area piece of F2 is its fixedly high interference zone, and the on-fixed region unit of F2 is its revocable high interference zone.F3 is for sector 3 in the time-frequency set, the fixed area piece of F3 is its fixing low interference region, the on-fixed region unit of F3 is its revocable low interference region, and for sector 1 and sector 2, the fixed area piece of F3 is its fixedly high interference zone, and the on-fixed region unit of F3 is its revocable high interference zone.

The low interference region size of on-fixed is SI_SIZE, and its value can be stipulated by agreement, also can be disposed by upper layer network unit, but must satisfy 0＜=SI_SIZE＜=M.Running time-frequency resource sets classification after the division is seen schematic diagram 2.

The high interference zone of three sectors (comprising fixing high interference zone and revocable high interference zone), schematic diagram 3. is seen in the indication of low interference region (comprising fixing low interference region and the low interference region of on-fixed)

Need to prove: when user's allocation schedule resource was given in the base station, the scheduling of carrying out resource allocation according to the ordering of above resource number was considered as positive sequence scheduling (comprise cyclic shift after order), for example: 1,2, ... N1, N1+1 ... N2, N2+1 ... N3-1, the order of N3 is a positive sequence.Then be the backward scheduling with the just antipodal sequential scheduling of positive sequence.

Optionally,, can give tacit consent to and comprise all time-domain resource, only frequency domain resource be distinguished for the division of above-mentioned running time-frequency resource.

For the sector that is numbered 1, be numbered 2 sector and be considered as first adjacent sectors, be numbered 3 sector and be considered as second adjacent sectors.

For the sector that is numbered 2, be numbered 3 sector and be considered as first adjacent sectors, be numbered 1 sector and be considered as second adjacent sectors.

For the sector that is numbered 3, be numbered 1 sector and be considered as first adjacent sectors, be numbered 2 sector and be considered as second adjacent sectors.

Step 3: after the user was linked into the base station, user type was determined according to user's feedback information in the base station: comprise central user and edge customer two big classes, wherein, feedback information can be following one of at least:

Received signal intensity indication information (Received Signal Strength Indication, abbreviate RSSI as), signal and interference-to-noise ratio (Signal to Interference plus Noise Ratio, abbreviate SINR as), signal and interference ratio (Signal to Interference Ratio abbreviates SIR as).
