The Discontinuous Reception (DRX) is the most effective timer-based mechanism for User
Equipment (UE) power saving. In Long Term Evolution (LTE) systems, the development of …

In the present scenario, an energy efficiency has become a matter of prime importance for
wireless networks. To meet the demands of an increased capacity, an improved data rate …

In urban vehicular ad hoc networks (VANETs), due to the high mobility and uneven
distribution of vehicles, how to select an optimal relaying node in an intra-street and how to …

Cellular networks have been undergoing an extraordinarily fast evolution in the past years.
With commercial deployments of Release 8 (Rel-8) Long Term Evolution (LTE) already …

As one of the key technologies in 5G networks, Carrier Aggregation (CA) is studied in this
paper. In CA, Component Carriers (CCs) can be activated and deactivated depending on …

In an LTE cell, Discontinuous Reception (DRX) allows the central base station to configure
User Equipments for periodic wake/sleep cycles, so as to save energy. DRX operations …

For next-generation wireless communications, the 3GPP Long Term Evolution-Advanced
(LTE-A) is the most promising technology which provides transmission rate up to 1 Gbps and …

Resource allocation and power optimization is a new challenge in multimedia services in
cellular communication systems. To provide a better end-user experience, the fourth …

Recently introduced UE types, such as Machine Type Communications (MTC) devices,
require extremely efficient power saving mechanisms to operate in harsh situations for a …

For the future-generation wireless communications, the carrier aggregation (CA) of third
generation partnership project (3GPP) long-term evolution-advanced (LTE-A) is one of the …
