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