Abstract:

Unique problems that hybrid automatic repeat request (HARQ) encounter in Time Division Duplex- high speed downlink packet access (TDD-HSDPA) systems are analyzed, especially when smart antennas are introduced. Accordingly, a novel mechanism combining HARQ with adaptive modulation and coding (AMC) is proposed. Dynamic system level simulator based on OPNET software is established to investigate the performance gain of the mechanism. Simulation results indicate that the scheme can reduce system block error rate (BLER) significantly and enhance system throughput.

Key words: high speed downlink packet access , hybrid automatic repeat request , adaptive modulation and coding , smart antennas
