User in the Loop: Mobility Aware Users Substantially Boost Spectral Efficiency of Cellular OFDMA Systems

Abstract: Abstract-Wireless cellular networks perform with a system spectral efficiency which depends on the user terminal distribution over the cell area. Due to an adaptive modulation and coding scheme which depends on the signal-to-interference+noise (SINR) ratio, the achievable data rate is typically an order of magnitude higher in the cell center compared to the cell edge. The performance of IMT-Advanced cellular radio systems like IEEE 802.16m and 3GPP LTE-A will strongly depend on algorithms to cope with the low … Show more

“…The user receives hints and incentives or penalties (quantified user information, QUI) in order to convince him to deviate from the default behavior (which is uncontrolled, open loop). The outcome is the user moving from one location to a better one [5] or postponing session traffic out of the busy hours [6].…”

“…The concept of user-in-the-loop was developed to control the user behavior in a wireless network so that a higher goal was achieved [9]. This goal can be the total spectral efficiency of a cellular network by convincing users to move from one location to a better one [10] or to postpone their use case out of the busy hour.…”
