Abstract

An embodiment of a method for user equipment feedback of performance metrics during dynamic radio switching is disclosed. The method may include the UE receiving an indication to switch from a first radio associated with a first radio access technology (RAT) of a communication system to a second radio associated with a second RAT of the communication system. The UE transmits the performance metrics to the second radio and switches from a first radio of the plurality of radios to a second radio of the plurality of radios, the first radio associated with the first RAT and the second radio associated with the second RAT.
