Abstract

[In cellular communication systems with optional D2D links, UEs can operate in either D2D mode or cellular mode for data transport [1–3]. In this chapter, we introduce mixed-mode D2D communication in which D2D links can operate in multiple modes through resource multiplexing. We study the problem of maximizing weighted D2D sum rate under cellular rate constraints by optimizing mixed-mode allocation and resource allocation in term of transmit power and subchannel assignment. A two-step approach is proposed by introducing energy-splitting variables such that mixed-mode allocation and resource allocation can be decoupled and optimized independently. The resulting algorithm can be distributive, requires little signaling overhead and has low computational complexity.]
