Summary:Technology for performing a Time Division Duplex (TDD) uplink-downlink (UL-DL) reconfiguration in a heterogeneous network (HetNet) is described. An evolved node B (eNB) may identify cluster metrics for a plurality of evolved node Bs (eNBs) in a cell cluster of the HetNet. The plurality of eNBs in the cell cluster may have a backhaul latency within a selected range. The eNB may select a TDD UL-DL configuration index for the plurality of eNBs in the cell cluster based in part on the cluster metrics. The eNB may transmit the TDD UL-DL configuration index to one or more user equipments (UEs) located within the cell cluster using a downlink control information (DCI) format. The TDD UL-DL configuration index may be transmitted on a Common Search Space (CSS) of a physical downlink control channel (PDCCH) on a UE-specific Primary Cell (PCell).
