Physical layer abstraction algorithms research for 802.11n and LTE Downlink

This paper discusses the physical layer abstraction algorithms for the integration of next-generation high-speed wireless local area network (WLAN) based on 802.11n and Long term evolution (LTE) cellular mobile communication network. Both the received bit information rate (RBIR) algorithm and the exponential effective signal-to-noise-ratio (SNR) mapping (EESM) algorithm are compared and analyzed in the heterogeneous network which is the integration of next-generation high-speed WLAN based on 802.11n and LTE cellular mobile communication network, and an appropriate method for the physical layer abstraction (PLA) algorithms selection is proposed by Link Level Simulation (LLS) and comparative analysis.
