Entanglement-assisted communication over a random-parameter quantum channel with channel side information at the encoder is considered. This describes a scenario where the quantum channel depends on the quantum state of the input environment. While Bob, the decoder, has no access to this state, Alice, the transmitter, performs a projective measurement on her environment and encodes her message accordingly. A full characterization of the entanglement-assisted capacity is given.
