The outer ring and the inner ring used in conjunction. The actual system must be set to take effect only with, or performance degradation.
SIR (tar) will be set up as a closed-loop radio environment changes: BLER packet error rate (generally set 10%), compared to set the measured and actual good SIR (tar) go out into decline.
The actual system is simple: receive the packet error, SIR (tar) rises.
Inter-cell power control
not only have x2 port (actually only signaling transfer point), but also a function of the coordination process.
PUSH channel power control
