Abstract
In heterogeneous cellular networks, small base stations (SBSs) in the coverage area of macro base station (MBS) cause significant inter-cell-interference (ICI). Intentional jamming interference (JI), caused by wideband jammers (WBJs), further worsens the uplink (UL) communications in the MBS coverage edge area. This letter investigates uniform and clustered WBJs’ deployment scenarios, denoted by C1 and C2, respectively. We employ decoupled association (DeCA) and reverse frequency allocation (RFA) to mitigate both JI and ICI. Results indicate that C2 is more disruptive than C1, and that a significant UL coverage improvement can be achieved by using DeCA along with RFA.
