Abstract :
HSDPA was firstly specified in release 5 of 3GPP to enhance higher downlink packet data rate on air-interface. There are many contributions to evaluate system performance and to investigate some advanced techniques in HSDPA, but most of which are focused on FDD system while TDD mode is rarely addressed. This paper studies HSDPA modeling with LCR TDD specifications, in which smart antenna techniques are often utilized. Not only smart antennas but N-channel HARQ is modeled in a dynamic system level TDD HSDPA simulator
