[en] We present boundary conditions for higher-spin fields in Minkowski spacetimes of dimension greater or equal to four giving an infinite-dimensional asymptotic symmetry algebra. The latter contains suitable generalisations of both BMS supertranslations and superrotations. We also show that Weinberg's factorisation theorem for amplitudes involving soft particles of any spin can be derived from supertranslation Ward identities.
