Uplink resource allocation algorithms with fractional power control as power constraints for OFDMA system

In this paper, two algorithms in resource allocation with fractional power control scheme are proposed and evaluated. In these algorithms, we joint chunk allocation and unequal power allocation in one chunk by considering fractional power control scheme as power constraint on each user to improve the sum of spectral efficiency of users and fairness among users. In order to evaluate our proposed algorithms, we compare the performances of our proposed algorithms with those of the previous algorithms with fractional power control scheme as power constraint in each user. From the simulation results are shown that our proposed algorithms can improve the sum of spectral efficiency and fairness among users in macrocell urban and suburban condition.
