Spectrum Sharing for LTE-A Network in TV White Space
Rural areas in the developing countries are predominantly devoid of Internet
access as it is not viable for operators to provide broadband service in these
areas. To solve this problem, we propose a middle mile Long erm Evolution
Advanced (LTE-A) network operating in TV white space to connect villages to an
optical Point of Presence (PoP) located in the vicinity of a rural area. We
study the problem of spectrum sharing for the middle mile networks deployed by
multiple operators. A graph theory based Fairness Constrained Channel
Allocation (FCCA) algorithm is proposed, employing Carrier Aggregation (CA) and
Listen Before Talk (LBT) features of LTE-A. We perform extensive system level
simulations to demonstrate that FCCA not only increases spectral efficiency but
also improves system fairness.Comment: 5 page
