Luisa,
maybe I misunderstood part of your inquire. However, some words can
help you think more specific about your outcome.
First, yes you should interpret your coefficient as you do in a linear
regression. Regard that the main difference between both techniques is
the shrinkage and liability aspects, not the coefficient or slope
interpretation.
Second, as I understood from your question a more accurate model of
change might be the trajectory over time from identity variation.

I am a Phd student and I have conducted one mix-model analysis using the command  xtmixed to analyze associations over 3 years of data. so I have  xi: xtmixed ....  || codigo: i.year, covariance(identity). So my question is can I interpret the coefficient as I interpret it in a linear regression? For example if I increase  one unit in my exposure the outcome will change Coef. over time? Or I should only  say that exposure and outcome are associated and in each direction, over time.
