Wireless communication networks play an important role in anybody's life during this information age. The technology is growing at a rapid rate and it becomes essential to provide a reliable linking to the system using an appropriate uplinking channel with the required Quality of Service (QoS). The work presented here deals with important Long Term Evolution (LTE) of techniques developed over last two decades. Power optimization of the mobile unit is the most desired operation which is discussed. Towards achieving seamless transmission, Frequency Hopping Spread Spectrum (FHSS) is used in wireless communication. Multi Input Multi Output - Orthogonal Frequency Division Multiplexing (MIMO-OFDMA) techniques are also adopted for combating fading and interference. Context aware link adaptation provides intelligent networking. Reconfiguration of uplinking also discussed in wide detail to match the essential requirement of mobility. Long term evolutions in scheduling and congestion control techniques are employed in the uplinking for suitable traffic management. Error detection and correction techniques play important role in restoring the original structure of the transmitted information.
