  This paper is on relay selection in uplink of an in-band full-duplex (IBFD)
cooperative cellular network. Assuming an orthogonal frequency division
multiple access (OFDMA) cellular network, we develop a relay selection and
resource allocation algorithm for this network. The relay selection algorithms
select the best relay based on distance between users and signal to
interference plus noise ratio (SINR) that operate in amplify and forward (AF)
mode. The optimization problem allocates the optimum subcarriers and powers to
all users to maximize the average sum-rate of the network. In addition, the
constraints of the optimization problem are quality of service (QoS) and
transmit power of each user. Simulation results illustrate the good performance
of the proposed method.
