As mobile devices grew rapidly over the past few years, the wireless data demand has increased exponentially. Due to the extremely high price of licensed spectrum, License Assisted Access (LAA) has been proposed to provide high capacity by extending LTE transmissions to the unlicensed spectrum that WiFi systems operate. Due to the coexistence with WiFi systems, mobility management has become a critical...
LTE License-Assisted Access (LTE-LAA) in unlicensed spectrum has drawn a lot of attention due to its appealing data traffic offloading potential. However, the coexistence of LTE and WiFi technologies in the same unlicensed bands needs careful design to avoid severe interference between them. In this paper, we propose a coexistence scheme to create opportunities for LTE-LAA small cells and WiFi devices...
Exponentially growing demand for mobile data is pushing the existing mobile networks to the limit. In addition to offloading traffic onto WiFi access points (APs), dual-band femtocells (DBFs) that can simultaneously access both the licensed and unlicensed bands have been proposed for cellular networks to further exploit the unlicensed spectrum. However, the coexistence between DBFs and WiFi in the...
