Abstract:
This disclosure provides systems, methods and apparatuses for user equipment (UE)-side and network-side mitigation of intermodulation (IM) interference, such as IM interference associated with multi-radio access technology communications. For example, the UE or a base station may detect an IM interference condition, and may perform an IM mitigation action based on detecting the IM interference condition. The UE may reduce an uplink transmit power so that IM interference on the downlink is reduced. Various base station IM mitigation actions are provided, such as suspending scheduling on a bearer, using a scheduling pattern that avoids concurrent transmission, reducing a maximum transmit power of an uplink grant of the UE, allocating resource blocks or bandwidth parts that do not overlap with an IM interference resource, changing a secondary cell group channel to a non-interfering channel, releasing a secondary cell group channel, deactivating a carrier, or changing a channel of the UE.
