A system for coordinating transmissions of power line communication (PLC) devices may include a processor and a memory. The processor may be configured to receive channel state information (CSI) from primary PLC devices. The primary PLC devices may be communicatively coupled to secondary PLC devices via collocated power lines, such as bundled power lines. Thus, the transmission of a primary PLC device over a power line to a secondary PLC device may be electromagnetically coupled onto the other power lines, thereby causing far-end crosstalk (FEXT) interference with respect to other secondary PLC devices. The processor may be configured to determine precoding information for compensating for the FEXT interference based at least on the received CSI. The processor may be configured to provide at least a portion of the precoding information to the primary PLC devices and to coordinate precoded transmissions of the primary PLC devices to mitigate the FEXT interference. |
