Abstract
By exploiting the advantages of the harvest-then-transmit (HTT) mode and the BackCom mode, two schemes that integrating the HTT mode and the BackCom mode are proposed for the WPCN in this chapter, i.e., the hybrid user scheme and the hybrid mode scheme. For the hybrid user scheme, the WPCN consists of two types of users, which adopt the HTT mode and the BackCom mode, respectively. While, each user can work in either the HTT mode or the BackCom mode for the hybrid mode scheme. The system throughput maximization problems are formulated for the proposed schemes and the optimal solutions are derived, respectively. The optimal solution for the hybrid user scheme shows that only the user in the BackCom mode with the largest backscatter rate can be scheduled. Moreover, the optimal users’ working mode permutation is studied for the hybrid mode scheme. Simulation results show the superiority of the proposed schemes over the single mode schemes in terms of system throughput.
