HARQ for dynamic change of the TDD UL/DL configuration in LTE TDD systems
Systems, methods, and apparatuses are directed to reconfiguring a time division duplex (TDD) uplink/downlink (UL/DL) configuration. A first TDD UL/DL configuration can be identified for a first radio frame. A second TDD UL/DL configuration can be identified for a second radio frame adjacent the first radio frame. The second TDD UL/DL configuration can be identified based, at least in part, on one or more subframes of the second TDD UL/DL configuration that can communicate hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) indicators for corresponding subframes of the first TDD UL/DL configuration.
