Game-Theoretic Mode Scheduling for Dynamic TDD in 5G Systems

Dynamic time-division duplexing (TDD) enables independent uplink/downlink mode scheduling at each cell, based on the local traffic. However, this creates cross-interference among cells. Thus, joint power allocation and problem becomes mixed-integer non-convex turns out to be NP-hard. We propose a low-complexity decentralized solution, where are decoupled. First, is allocated in fashion, then modes scheduled by non-cooperative game achieve mixed-strategy Nash equilibrium. consider two possible approaches compute payoffs game, according model entailed communication overhead Simulation results presented for an outdoor dense small-cell scenario, showing that our outperform static TDD significantly.
