Abstract
An apparatus and method for managing interference to facilitate allocation of a dynamic uplink and downlink configuration are disclosed herein. Determining whether a first cell causes interference less than a pre-determined threshold level to one or more neighboring cells or whether flexible subframes of radio frames associated with the one or more neighboring cells operate as downlink subframes. In response to the determining condition being met, allocating a first flexible subframe of a first radio frame associated with the first cell to operate as a downlink subframe at normal transmit power level. In response to the determining condition not being met, allocating the first flexible subframe of the first radio frame associated with the first cell as one of a downlink subframe operating in a reduced transmit power level or as an uplink subframe.
