Production and suppression of heavy quarkonium states are one of the most studied topics in heavy ion collision field. Recently, the experimental data regarding quarkonia suppression have been obtained and analysed by CMS and ALICE collaboration at 
TeV. In this article, we would like to provide the physical interpretation to these data by using our recently proposed kinetic model for quarkonia suppression. In the recent past, our kinetic model provides satisfactory results for quarkonia suppression at 
GeV and 2.76 TeV from STAR collaboration at RHIC and from CMS collaboration at LHC, respectively. These results suggest that the effect of regeneration becomes quite important at LHC energies. In the present work, we have improved our model by incorporating another physical process which regenerates the singlet quarkonia states in addition to the regeneration by radiating a soft gluon. We proceed with our improved model calculations to obtain the variation of nuclear modification factor for different quarkonia states with respect to centrality at TeV. Further, we have calculated the nuclear modification of charmonia states with respect to bottomonia states. This work will help in putting a stringent constraint on our model parameters.
