Adjacent Channel Interference Aware Joint Scheduling and Power Control for V2V Broadcast Communication

This paper proposes scheduling and power control schemes to mitigate the impact of both co-channel interference (CCI) adjacent channel (ACI) on direct vehicle-to-vehicle broadcast communication. The objective is maximize number vehicles that can communicate with prescribed requirement latency reliability. joint problem formulated as a mixed Boolean linear programming (MBLP) problem. A column generation method proposed reduce computational complexity From problem, we formulate scheduling-alone (given allocation) (BLP) control-alone schedule) an MBLP numerically sensitive due high dynamic range values ratio (ACIR) values. Therefore, novel sensitivity reduction technique, which compute stable optimal solution at price increased complexity, proposed. Numerical results show ACI, just CCI, serious in (V2V) communication near-far situations hence should not be ignored, its reduced by proper control.
