8.1 Introduction

The fifth generation (5G) of cellular networks is expected to provide a wide variety of high rate multimedia services, with speeds of 300 Mbps and 60 Mbps in the downlink and uplink, respectively, at 95% of locations and times [1]. The 5G communication platform is seen as a global unified standard with seamless connectivity across existing standards: high speed packet access, Long-Term Evolution-Advanced (LTE-A), and wireless fidelity (WiFi). Some of the emerging features and trends of 5G networks are:

  • multi-tier dense heterogeneous networks [2, 3]
  • device-to-device (D2D) and machine-to-machine (M2M) communications [3, 4]
  • densification of the heterogeneous base stations (e.g., extensive use of relays and small cells) [5]
  • cloud-based radio access network [3]
  • integrated use of multiple radio access technologies [6]
  • wireless network virtualization [3]
  • massive and 3D MIMO [3, 7]
  • millimeter waves [8]
  • full duplex [9] communications.

Conventional 3G systems are single-tier and based on code division multiple access (CDMA) technology. In CDMA systems, all network nodes use the same frequency resource and are distinguished from each other by different pseudo-random spreading codes, which are not exactly orthogonal. Therefore, interference among the nodes is closely related to transmit power. Through efficient power control and spreading schemes ...
