Antenna port (P_B) number and physical downlink control channel (PDCCH) interference effect etc.), it can ignore.
In one example, if RNTP threshold value is not able to satisfy the requirement of interfered base station, for example, reduced power water
It is flat not low enough so as not to influencing the service for UE, or the object with reduced transmission power for interfered base station
Reason resource is not suitable for being disturbed base station using to dispatch UE or any other appropriate situation, then being disturbed base station can
To report the RNTP bitmap and/or RNTP threshold value of its desired each PRB to interference base station, rather than as in the prior art that
Its own transmission power frequency domain distribution that will be configured only is reported to adjacent cell in each base station of sample.In this way, base is interfered
Station is possible to pay the utmost attention to such transmission power configuration for completing itself from the prior information for being disturbed base station, so that function
Rate configuration meets the requirement for being disturbed base station as far as possible, to realize significantly more efficient interference coordination.
