We discuss the quantum Poincar\'e symmetries of the $\varrho$-Minkowskispacetime, a space characterised by an angular form of noncommutativity. Weshow that it is possible to give them both a bicrossproduct and a Drinfel'dtwist structure. We also obtain a new noncommutative $\star$-product, which iscyclic with respect to the standard integral measure.
