A model for current drive by electron Landau damping and transit time magnetic pumping in the ICRF regime is introduced in the global wave code LION in order to calculate global current drive efficiency and current profiles. The frequency regime near the fourth harmonic of the deuterium cyclotron frequency is a suitable regime for demonstrating current drive in JET. Trapped particle effects are found to be a severe limitation for this low frequency regime. They give rise to an even more strongly peaked current profile than the power deposition profile.
