In some wireless systems (e.g., 5G new radio (NR) systems), a user equipment (UE) may experience coexistence interference when using collocated radio transceivers to simultaneously communicate using different radio access technologies (RATs). To mitigate the coexistence interference, the UE may transmit a configuration request to a base station, where the configuration request may identify that the UE is operating on multiple RATs and identify that the UE is experiencing coexistence interference. Aspects of the present disclosure may further provide techniques for coexistence interference mitigation in wideband systems by allowing the UE to indicate the specific bandwidth parts (BVVPs) that are impacted by IDC interference to the base station such that the network can resolve the IDC interference by reconfiguring the bandwidth, instead of performing inter-frequency handover or removing/deactivating affected SCells.
