Abstract
In this paper strategies for dynamic user grouping and shared frequency resource assignments for OFDMA systems are proposed. The users are grouped based on their modulation type and a metric for this purpose is introduced which considers tradeoffs between maximum rate and minimum allocated resources per user. The available resources are distributed through the modulation groups based on fairness criteria. Equal power allocation on the loaded subcarriers of each user is further incorporated. Simulations show that under equal power assumptions the algorithm proposed in the following can bring a better exploitation of the available bandwidth and can provide good QoS to an increased number of users simultaneously.
