N2 - This paper investigates the performance of user-centric joint transmission coordinated multi point transmission (JT-CoMP) in a single-tier network taking radio resource management into account. One of the main challenges in user-centric JT-CoMP is how to balance between signal to interference noise ratio (SINR) gain and loss of resource availability. To provide this balance, an optimal power level difference (PLD) value that determines how many users should operate under CoMP mode must be carefully chosen. Also, a proper radio resource assignment for JT-CoMP is needed. This paper studies the impact of choosing different PLD values on per-user throughput for CoMP and non-CoMP users. It also describes how radio resources in JT-CoMP systems are assigned. Simulation results demonstrate that a small PLD value such as 5 dB provides a better balance between SINR gain and loss of resources compared with higher PLD values such as 10 dB and 15 dB. Results also show that radio resource management has significant impact on the throughput of CoMP and non-CoMP users.
