| Summary: | Interference is an important and challenging problem
faced by the D2D underlaid cellular networks. In this
paper, we focus on the user-level interference under multicasting
scenarios. Rather than the traditional pairwise way of
D2D communications, we propose to implement the information
exchanging through a groupwise way. Through introducing the
idea of network coding, the proposed scheme is able to utilize
the interference as valid signals to enhance the receiving performance,
instead of only managing or controlling it. Both theoretical
analysis and simulation results prove that the proposed scheme
achieves better SINR performance and lower resources occupation
than the traditional pairwise D2D transmission schemes. |
