Sum of two signal which have differents data rate

I have two source with different sample times. I have to sum up them in the channel. When I run the simulation the following message appear on the board: "_Warning: Inconsistent sample times. Sample time ([0.0005, 0]) of signal driving input port 2 of 'channels_48_vs_48/Error Rate Calculation' differs from the expected sample time ([0.001, 0]) at this input port._"
How can I properly sum up two signal - frame based - with different sample times?

Hello,
I have the same issue. I want to estimate the perturbation caused by a system to another system. I've created the two signals (coding / modulation , ...) but they have two different samples rates determinated by the system parameters.
I guess the addition of the two signals must be made at the sample time of the fastest signal ? In that case, the only solution is to interpolate the signals ?
And what is the impact of an interpolation for the useful signal ?
Thanks in advance
