Cellular networks have been constantly evolving to improve the spectral efficiency of the system and provide high data rates. The third generation partnership Project (3GPP) introduced the long term evolution (LTE) standard with the primary aim of evolving the radio access technology and the system architecture. Since then, 3GPP LTE evolved to LTE-Advanced (LTE-A) to fulfill the requirements of international mobile telecommunications-advanced (IMT-A) set by international telecommunication union radio-communication sector (ITU-R), also defined as the fourth generation (4G) of mobile technology and recently, LTE-A has further evolved to LTE-A Pro. These markers are indications of major enhancements in the 3GPP LTE cellular networks. In order to enable this constant evolution, it is required to not only improve the existing features, but also introduce novel technologies. However, channelizing such new technologies from theoretical setup to more practical systems such as 3GPP LTE networks is quite non-trivial due to the strict constraints of the real-world. The research work in this thesis deals with different aspects of radio resource management (RRM) to enable effective deployment of advanced wireless technologies with evolution of 3GPP LTE. The key contributions involve interference coordination in multi-user multiple input multiple output (MU-MIMO) system, fast synchronization to enable device-to-device (D2D), efficient resource allocation of control signaling in massive carrier aggregation (CA) and advanced medium access layer (MAC-layer) scheduling framework to deal with multi-user multi quality-of-service (multi-QoS) traffic conditions. Extensive system and link level evaluations are conducted to examine the performance of proposed techniques in a 3GPP LTE and beyond framework and provide validation for applicability in industry.
