Abstract:
The application discloses a method for performing interference coordination between adjacent cells supporting dynamic TDD uplink and downlink configuration by a first evolved Node B (eNB). The method includes that: receiving, downlink interference degree information from a second eNB, wherein the downlink interference degree information is used for indicating a degree that uplink transmission of the second eNB is interfered by downlink transmission in a conflict subframe; and determining, according to the downlink interference degree information, whether to adjust downlink transmit power in the conflict subframe, if the downlink transmit power in the conflict subframe is to be adjusted, transmitting a CSI report configuration to UE of current cell, and configuring the UE of current cell to report a set of CSI respectively for the conflict subframe and a non-conflict subframe. By the solution of the present application, serious uplink and downlink interference between the adjacent cells can be avoided when the adjacent cells use different TDD uplink and downlink configurations.
