Abstract

We study the coexistence of FDD flexible duplexing systems, where a cellular network may use FDD uplink band for downlink transmission. As a result, adjacent channel emissions will change, with an effect to networks operating on adjacent channels. To stabilize the adjacent channel interference, equalizing downlink power control is considered, such that a flexible duplexing cell radiates in downlink a power density which is equivalent to the mean uplink transmit power of the cell. We derive a closed form equation for the transmit power, and evaluate coexistence performance in a heterogeneous network using the proposed power control.
