The LTE radio interface for 3GPP Release 8 was specified recently. This article describes
the LTE link-layer protocols, which abstract the physical layer and adapt its characteristics to …

A contemporary perspective on transmit antenna diversity and spatial multiplexing is
provided. It is argued that, in the context of most modern wireless systems and for the …

This paper studies the performance of hybrid-ARQ (automatic repeat request) in Rayleigh
block-fading channels. The long-term average transmitted rate is analyzed in a fast-fading …

This paper studies the tradeoff between channel coding and ARQ (automatic repeat request)
in Rayleigh block-fading channels. A heavily coded system corresponds to a low …

For a large class of non-delay-critical applications (eg, buffered video streaming or data
transfer from cloud services to local devices), end-to-end throughput becomes the most …

Mobile Machine-to-Machine (M2M) market is expected to grow dramatically in the upcoming
years; predictions agree that the majority of wireless traffic will correspond to this type of …

Future cellular networks aim to improve the data rate to users in office and residential
buildings. Wireless relaying is one of the possible solutions. In this approach, a relay is …

Mobile internet devices are among the fastest growing markets in consumer electronics. A
big issue with these devices is the low battery capacity that requires the user to recharge the …

Load imbalance that reduces network performance is a serious problem in 3GPP Long Term
Evolution Networks. Load imbalance occurs in communication networks due to non-uniform …

In this chapter, we provide a brief yet comprehensive overview of current Long Term
Evolution (LTE) systems and beyond. We begin presenting the baseline technology and the …
