Synchronized Code Division Multiple Access, TD-SCDMA) the spuious of system, intermodulation, second harmonic
Etc. different system interference, the uplink interference level of A cells can be made higher than other cells, and then initiation uplink transmission power and uplink are done
Disturb the problem of horizontal mutually soaring.
How while uplink power control is carried out to inhibit uplink interference, uplink transmission power and uplink interference are solved
The problem of horizontal mutually soaring, the prior art provides solution not yet.
