Interference Management for Advanced LTE Spectrum Solutions

Electrical and Computer Engineering
NYU Community Event

Speaker: Dr. Zinan Lin

Faculty host: Professor Elza Erkip

The rapid development of mobile technology requires more bandwidth to support video and data-intensive applications.  The Federal Communications Commission (FCC) estimates that by 2014, mobile device traffic will increase by 35x over 2009 levels. While the Long Term Evolution (LTE) standard and other advances may provide up to a fivefold increase in capacity, this increase is far below the projected demand. Dynamic spectrum management (DSM) is one of the comprehensive approaches to reducing the anticipated strain on the network by taking advantage of underutilized spectrum, such as TV white space (TVWS). In most cases, TVWS channels could be shared by multiple secondary networks. This introduces unpredictable interference situations and requires enhanced power control and interference management schemes to solve uncoordinated interference problems.

In this talk, we will first show the vision of future network of network and the concept of TVWS. Second, we will give an overview of Radio Resource Management (RRM) technologies supported by the LTE/LTE-advanced (LTE-A) standards. Particularly, we focus on the power control and interference management technologies. Last, we will present challenges of the interference management of LTE operation in TVWS and propose potential power control mechanisms and interference management solutions used in license exempt bands, e.g., TVWS bands.
