The eNB can receive, from a user equipment (UE), a UE capability report that indicates the UE supports a TDD UL-DL reconfiguration functionality. The eNB can transmit, to the UE, a configuration to enable TDD UL-DL reconfiguration at the UE. The eNB can transmit, to the UE, a TDD UL-DL reconfiguration signal in a downlink control information (DCI) message. The UE can be configured to update a TDD UL-DL configuration of the UE based on the TDD UL-DL reconfiguration signal transmitted on a physical downlink control channel (PDCCH) in preconfigured downlink or special (DL/S) subframes by the eNB."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time division duplex (TDD) uplink downlink (UL-DL) reconfiguration","description":"An evolved node (eNB) operable to transmit a Time Division Duplex (TDD) uplink-downlink (UL-DL) reconfiguration in a heterogeneous network (HetNet) is disclosed.
