The ABS subframe of larger proportion is configured, to reach to limit user in the range of the first base station 11 in the signal sent
The data transmission of terminal, promotes the data transmission of user terminal in the range of the second base station 12, thus reduces the
The interference to the second base station 12 of one base station 11；Or, the first base station 11 is second on the frequency domain sending signal
The frequency sub-band that in the range of base station 12, region distribution is more, to promote that the user terminal in the range of the second base station 12 exists
Carry out data transmission on these frequency sub-band, further reduce the interference to the second base station 12 of first base station 11.
Specifically, ABS subframe pattern is the concrete method of salary distribution of ABS subframe, makes the configured length of ABS
For N, N number of subframe will be divided into by a complete frame fragment, as N=8, ABS subframe pattern can be concrete
Being 10101010,11110000 or 11111111 etc., wherein 1 represents the normal-sub at this in time domain
Frame replaces to ABS subframe, and 0 represents normal sub-frames.
Frequency sub-band pattern is the concrete method of salary distribution of frequency range, and the configured length making frequency range is M, will one complete
Whole frequency range is divided into M frequency sub-band, and such as M=8, frequency sub-band pattern can be specially 11010100,11101000
Or 10000111 etc., wherein 1 represents that the frequency sub-band of community is distributed to be disturbed in base station, and 0 represents base station distribution
To the frequency sub-band of interfered cell.
It should be noted that and can not obtain, according to ABS sub-frame ratio or frequency range ratio, ABS that determines
The frame style or frequency sub-band pattern, if ABS sub-frame ratio is 0.5, ABS subframe pattern can be 10101010,
11110000,00001111 or 01111000 etc..And may determine that ABS according to ABS subframe pattern
Frame ratio, as ABS subframe pattern be 11000000 ABS sub-frame ratio be 0.25.Therefore, the overall situation
Controller would generally use other subframe assignment constraint rules after generating ABS sub-frame ratio or frequency range ratio
Further determine that ABS subframe pattern and frequency sub-band pattern, as LTE (Long Term Evolution, for a long time
Evolution technology) in HARQ (Hybrid automatic repeat request, mixed automatic retransmission mechanism)
