Dear Gabriel, As I mentioned in a previous email, the module expects a basename, so it won't recognize the @mapsetname, be it permanent or any other. Therefore if your Landsat bands names are for example, landsat_date_B1, landsat_date_B2, landsat_date_B3 and so on, in the input parameter you only have to put "landsat_date_B" and the module will read all the bands available in the mapset with that basename.
As output, you need to set a basename again. Please, take a look at the examples in the manual page ( https://grass.osgeo.org/grass76/manuals/i.landsat.toar.html). If there's anything that doesn't seem clear there, let us know so we can enhance it.
