摘要

The number of subscribers and cellular traffic demand had grown dramatically, which is an urgent challenge face on the cellular network and system performance. Due to the problem, power allocation was exploited by many researchers in order to improve the system performance, e.g. implementation of fractional power control (FPC) as the power constraint in single carrier - frequency division multiple access (SC-FDMA) in term of uplink resource allocation algorithm and fractional power coefficient as the uplink control in heterogeneous small cell networks. Both of them could enhance any system performance i.e. spectral efficiency, transmission rate and energy efficiency. Even though any tradeoff would be the handicap in order to maintain the system's quality of service (QoS), such as the lower fairness index at the first one, worse outage probability and also significant interference at the second. In this paper, a dynamic uplink power control algorithm is proposed to solve the problem, especially to manage that tradeoff within user's velocity-based scenario (UVS). Beside to enhance the system performance improvement, the implementation of the proposed algorithm is also addressed as the way to investigate the 5G wireless technology, especially in a femtocell network. Numerical results as shown by this proposed indicate the obtained enhancement of the system i.e. improvement of the energy efficiency by 10%-99%.
