An apparatus of an enhanced Node B, the apparatus comprising: a memory; and processing circuit comprising: means for decoding an overload indication and a first uplink/downlink (UL/DL) configuration received from a neighboring eNB; means for adapting a second UL/DL configuration for at least one user equipment (UE) responsive to the received overload indication and first UL/DL configuration; means for encoding the adapted second UL/DL configuration in downlink control information (DCI) of a physical downlink control channel (PDCCH); meas for masking a cyclic redundancy check (CRC) for the PDCCH with a radio network temporary identifier (RNTI) reserved for signaling UL/DL configurations; a means for encoding the PDCCH for transmission to the at least one UE; wherein the memory is configured to store the adapted second UL/DL configuration.
