WebA. Uplink Power Control In order to improve inter-cell interference, uplink power control (ULPC) can be utilised on the reverse link. We in-corporate a modest open loop scheme which does not attempt to compensate for fast fading. We assume perfect path loss estimation at the terminal, with each terminal transmitting with Web3.1 Open Loop Power Control . Open Loop Power Control is mainly implemented in the user equipment (UE). The UE measures the downlink signal status, compensates the uplink path loss and controls the interference in neighboring eNBs. With OLPC, the UE needs some stat-ic/semi-static configuration parameters to be signaled by the WebDC voltage outer loop and inductance current inner loop control are adopted as the control algorithm. In simulation, controller is sampled at fs = 10 kHz (100 μs) to mimic the operation inside a DSP, while the rest of the system, including inverter, filter, etc., are sampled at a higher rate to mimic the behavior of a inverter in real time (at least greater … greenlee county az real estate
