DOWNLINK ASSIGNMENT INDEX (DAI) AND TIMING DESIGN FOR TIME DIVISION DUPLEXING (TDD) ENHANCEMENT FOR INTERFERENCE MANAGEMENT AND TRAFFIC ADAPTATION (eIMTA)

摘要

Systems, methods, apparatuses, and computer program products for an uplink (UL) downlink assignment index (DAI) design and corresponding timing for TDD enhanced interference management and traffic adaptation (eIMTA). One method includes re-using two-bit transmit power control (TPC) in UL grant as UL DAI to indicate the total number of subframes with PDSCH transmissions and with PDCCH indicating downlink SPS release to the UE in a corresponding downlink subframe set.
