Chen Shuping, Jiuhui Du, Peng Mugen, Wang Wenbo · 2006
HSDPA proposed in 3GPP is the best evolution of current UMTS to support high data rate services. It adopts numbers of enhanced techniques including AMC, HARQ, fat-pipe scheduling etc. This paper investigates the performance of different HARQ schemes considered for TDD-HSDPA system on system level. Special address is put on the affect of smart antennas. A kind of improved full IR is also proposed and investigated
