Detection of intermodulation issues and transmission scheme configuration to remedy intermodulation issues

An apparatus, comprising a processing element configured to cause a base station to:

• receive, from a wireless device, a capability indicating that simultaneous transmission on dual uplink carriers is not supported by the wireless device due to a potential intermodulation issue associated with a dual connectivity configuration of LTE and NR for one or more band combinations;
• receive, from the wireless device, an indication that the wireless device supports reporting intermodulation issues associated with dual connectivity on LTE and NR;
• provide an indication that the wireless device is allowed to report the intermodulation issues;
• receive, from the wireless device, an indication that an intermodulation issue associated with dual connectivity on LTE and NR is occurring at the wireless;
• determine to configure the wireless device to use a single uplink carrier at a time based at least in part on one or more of the capability and the indication of the intermodulation issue.

A base station, comprising:

• an antenna;
• a radio coupled to the antenna;
• and
• a processing element coupled to the radio;
• wherein the base station is configured to:
• receive, from a wireless device, a capability indicating that simultaneous transmission on dual uplink carriers is not supported by the wireless device due to a potential intermodulation issue associated with a dual connectivity configuration of LTE and NR for one or more band combinations;
• receive, from the wireless device, an indication that the wireless device supports reporting intermodulation issues associated with dual connectivity on LTE and NR;
• provide an indication that the wireless device is allowed to report the intermodulation issues;
• receive, from the wireless device, an indication that an intermodulation issue associated with dual connectivity on LTE and NR is occurring at the wireless device;
• and
• configure the wireless device to use a single uplink carrier at a time based at least in part on one or more of the capability and the intermodulation issue.
