Downlink Error Rates of Half Half-Duplex Users in Full-Duplex Duplex Networks Over a Laplacian Inter Inter-User User Interference Limited and EGK Fading
Abstract: This paper develops a mathematical framework to study downlink error rates and throughput for half-duplex duplex (HD) terminals served by a full-duplex full (FD) base station. The developed model is used to motivate long term pairing for users that have a non-line line of sight (NLOS) interfering link. Consequently, we study the interferer limited problem that appears between NLOS HD users users-pair that are scheduled on the same FD FD-channel. channel. The distribution of the interference is first characterized via its distribution function, which is derived in closed form. Then, a comprehensive performance assessment for the proposed pairing schem scheme is provided by assuming Extended Generalized-K Generalized fading for the downlink and studying different modulation schemes. To this end, a unified closed closed-form expression for the average symbol error rate is derived. Furthermore, we show the effective downlink throughput throughput gain harvested by the pairing NLOS users as a function of the average signal-to-interference-ratio signal ratio when compared with an idealized HD scenario with neither interference nor noise. Finally, we show the minimum required channel gain pairing threshold to harvest downlink throughput via the FD operation when compared with the HD case for each modulation scheme.
