摘要: The purpose of a Beyond 4G (B4G) radio access technology, is to cope with the expected exponential increase mobile data traffic in local area (LA). requirements related physical layer control signaling latencies and hybrid ARQ (HARQ) round trip time (RTT) are order ~1ms. In this paper, we propose flexible orthogonal frequency division multiplexing (OFDM) based duplex (TDD) subframe structure optimized for B4G LA environment. We show that proposed optimizations allow very frequent link direction switching, thus reaching tight HARQ RTT requirement significant latency reductions compared existing LTE-Advanced WiMAX technologies.
