Co-interference between Wi-Fi and cellular radios, e.g., in a wireless communication device that is concurrently operating using Wi-Fi and cellular radio technologies, is managed using victim tables that indicate channels that can potentially co-interfere. The victim tables are implemented as lookup tables (LUTs) that include entries for combinations of cell band and Wi-Fi and/or channel. The entries indicate whether the Wi-Fi channel is safe or should be avoided because there is a high likelihood of co-interference. The entries also include a power back off that indicates that the Wi-Fi subsystem is to back off its transmission power setting by a specified amount to become a safe channel.
