A number of methods reduce inter-cell interference under multi-carrier configuration. One of the methods includes a first NodeB transmitting, to a second NodeB, Primary Component Carrier (PCC) information or Primary cell (PCell) information configured by the first NodeB for a UE served by the first NodeB. The method also includes the second NodeB responding to the first NodeB. As such, when configuring CA for a UE served by the second NodeB, the second NodeB is able to configure the PCC information or PCell information for the UE served by the second NodeB according to the PCC information or PCell information indicated by the first NodeB. |
