Introduction

Hu, Rose Qingyang; Qian, Yi

Pages: 1 –5

[Mobile communications, which enable anytime and anywhere ubiquitous connectivity, have been an integrated part of our daily life. With the widespread adoption of smart mobile devices such as smart phones, tablets and ultra-portable laptops and the subsequent explosive expansion of...

Heterogeneous Network Model and Preliminaries

Hu, Rose Qingyang; Qian, Yi

Pages: 7 –16

[A two-tier heterogeneous network model in LTE is studied throughout this book. As shown in Fig. 2.1, consider downlink communications in a heterogeneous cellular network with high transmit power macro evolved Node Bs (MeNB) and low transmit power small evolved Node Bs (SeNB) or relay nodes (RN)....

Mobile Association for Heterogeneous Networks

Hu, Rose Qingyang; Qian, Yi

Pages: 17 –35

[Traditional way of mobile association is based on a best-power approach where each UE associates with the eNB that it receives the highest power from. In heterogeneous networks, however, due to the disparity in transmit power of the macro and small cell eNBs, if best-power based mobile...

Interference Management in Heterogeneous Networks with Fractional Frequency Reuse

Hu, Rose Qingyang; Qian, Yi

Pages: 37 –51

[As illustrated in Fig. 4.1, in an FFR scheme, the total sub-bands F is divide d into two parts, f1 and f2 with size F1 and F2, respectively.]

Radio Resource Allocation in Heterogeneous Networks

Hu, Rose Qingyang; Qian, Yi

Pages: 53 –78

[Intra-cell coordinated multiple point (CoMP) transmission is discussed in Chap. 2. Downlink intra-cell cooperative transmission and optimal intra-cell CoMP resource allocation schemes are investigated in heterogeneous networks with cooperative relays in [1–3]. In this chapter, radio resource...

Conclusion

Hu, Rose Qingyang; Qian, Yi

Pages: 79 –80

[Global mobile traffic increases 66 times with an annual growth rate of 131 % between 2009 and 2014. On the contrary, the peak data rate from 3G to 4G wireless technology only increases 55 % annually. Clearly there is a huge gap between the capacity growth of new wireless access technologies and...
