A nontrivial protocol for teleporting an unknown N -qubit W-like state is proposed. The consumed resource is only ( N -1) shared ebits and 2( N -1) bits of classical communication, while the technique involves only controlled-NOT gates and single-qubit measurements/operations. The rule for reconstruction of the desired state at the receiving station is worked out explicitly in the most general case of an arbitrary N ≥ 3. The protocol is within the reach of present technologies.
