Exploiting the User-Level Interference Based on Network Coding in D2D Underlaid Cellular Networks

Abstract EN

Interference is an important and challenging problemfaced by the D2D underlaid cellular networks.

In thispaper, we focus on the user-level interference under multicastingscenarios.

Rather than the traditional pairwise way ofD2D communications, we propose to implement the informationexchanging through a groupwise way.

Through introducing theidea of network coding, the proposed scheme is able to utilizethe interference as valid signals to enhance the receiving performance,instead of only managing or controlling it.

Both theoreticalanalysis and simulation results prove that the proposed schemeachieves better SINR performance and lower resources occupationthan the traditional pairwise D2D transmission schemes.
