  In the framework of light-cone formulation of relativistic dynamics,
arbitrary spin massless fields propagating in the four-dimensional AdS space
are studied. For such fields, the complete list of light-cone gauge cubic
interaction vertices is obtained. Realization of relativistic symmetries on
space of light-cone gauge massless AdS fields is also obtained. The light-cone
gauge vertices for massless AdS fields take simple form similar to the one for
massless fields in the flat space.
