It’s quite common for new wireless user equipment (UE) devices to support multiple radio transceivers. For example, a single UE device may support LTE, WiFi, Bluetooth, and GNSS. This makes it challenging to prevent coexistence interference between different co-located radio transceivers.
Figure 1 shows an example of such a situation.

This blog post describes some of potential solutions for coexistence interference. For more information, I encourage you to look at 3GPP’s technical report
