Abstract In-band full duplex (FD) communications are attracting more attention due to their potential to double the spectral efficiency (SE). However, severe inter-cell interference will degrade the system performance. A fractional FD (FFD) resource allocation strategy was developed to reduce the effect of severe interference in the system SE. The radio resources are first classified into FD resource blocks and half duplex resource blocks with all the blocks allocated to the users based on the channel condition of each user. The Wyner model was used to evaluate the system performance. The user positions were used to partition the resource blocks and as the user classification criterion. Simulate SE and optimal partition radii for different classification thresholds show that this method can significantly improve the system SE.
