B, the frequency black hole of what this TDD system detected belong to other wireless communication systems.
These frequency black holes can be tightly adjacent or tightly not adjacent with native system frequency range.
As shown in Figure 2, first edge frequency range is the frequency range that 203 (or 206) take, second edge frequency range is the frequency range that 205 (or 208) take, the successive bands of the first monitored edge frequency range refers to the frequency range 201 adjacent with 203 (or 206), and the successive bands of the second monitored edge frequency range refers to the frequency range 202 adjacent with 205 (or 208).Step 402: described neighboring trace leakage value is fed back to base station by subscriber equipment, described neighboring trace is revealed compared with the threshold value pre-set by base station, determines the delivery time in edge frequency range, power, frame length according to comparative result, and frequency subband width and position.Described delivery time and power comprise the delivery time of down direction and the delivery time of power and up direction and power.
In general, base station by described neighboring trace leakage value and the threshold comparison that pre-sets, if neighboring trace leakage value is greater than threshold value, then the delivery time of edge frequency range, power, frame length, and frequency subband width and position adjust, otherwise foregoing is not adjusted.Described being adjusted to reduces transmitted power, shortening frame length, reduces subband width.Preferably, multiple threshold value (M can be pre-set
