Dans les réseaux de radio cognitive symbiotique (CR), les utilisateurs de CR (CU) peuvent assister à la transmission primaire pendant un temps de coopération et obtenir un temps incitatif pour leur propre transmission de données. Dans cette lettre, nous étudions le problème de maximisation du débit dans les réseaux CR symbiotiques. Sous les contraintes de symbiose et de puissance de transmission, nous visons à trouver le temps de coopération optimal pour faciliter la transmission primaire et les allocations de puissance entre les CU. Compte tenu du temps de coopération, les allocations de puissance optimales peuvent être résolues par un remplissage d'eau à plusieurs niveaux (MWF) avec des limites de volume individuelles. Une analyse théorique est présentée sur le temps de coopération et un algorithme de bissection modifié de faible complexité est proposé pour trouver le temps de coopération sous-optimal. Les résultats de la simulation montrent que l’efficacité de l’utilisation du spectre peut être considérablement améliorée à mesure que le nombre de CU augmente.

Abstract: In the symbiotic cognitive radio (CR) networks, the CR users (CUs) may assist the primary transmission in a cooperation time, and obtain an incentive time for their own data transmission. In this letter, we study the throughput maximization problem in the symbiotic CR networks. Under the symbiosis and transmit power constraints, we aim to find the optimal cooperation time to assist the primary transmission and power allocations among the CUs. Given the cooperation time, the optimal power allocations can be solved by multi-level water-filling (MWF) with individual volume limits. A theoretical analysis is presented on the cooperation time and a modified bisection algorithm with low complexity is proposed to find the sub-optimal cooperation time. Simulation results show that the spectrum usage efficiency can be significantly improved as the number of CUs increases.

AB - In the symbiotic cognitive radio (CR) networks, the CR users (CUs) may assist the primary transmission in a cooperation time, and obtain an incentive time for their own data transmission.
