Signal reception power) threshold value that is higher than, then corresponding candidate resource needs are excluded；
If step2 exclude after, surplus resources ratio be lower than 20%, threshold value is promoted into 3dB, re-executes and excluded
Journey, until surplus resources ratio reaches at or above 20%；
Step3: S-RSSI (received signal strength indicator) measurement and sequence are carried out to candidate resource, select S-RSSI survey
20% minimum resource of magnitude carries out resource selection from above-mentioned 20% candidate resource by high level.
