Resource Allocation for Multicarrier Multicell NOMA-IBFD Cellular System with QoS

In this work, we propose a resource allocation al-gorithm for multicell cellular system featuring a Nonorthogonal multiple access (NOMA), In-band full duplex (IBFD) enabled base station for data transfer. The simultaneous transmission of multiple signals on the same frequency resource introduces several interferences and necessitates higher transmission powers to meet user's quality of service (QoS) requirements. To address this challenge, we propose a heuristic to determine subcarrier and power allocations that minimize the total downlink power budget with QoS constraints for each user. We also present decodability order for downlink NOMA in the presence of uplink users. Through numerical simulations we show that NOMA-IBFD requires lower transmit powers to meet QoS compared to the OMA-IBFD system, despite having more interference terms.
