Abstract
A wireless communication device (A) is configured to receive user data from a radio network node () in a wireless communication system () that includes a data channel () over which user data is transmitted and a control channel () over which control data is transmitted. The device (A) receives over the control channel () a hierarchically-modulated symbol () which conveys control data on a control-data modulation layer (A) and conveys user data on a user-data modulation layer (B). The control-data modulation layer (A) is recoverable via demodulation at a lower order, and the user-data modulation layer (B) is recoverable via demodulation at a higher order. The lower order is lower than the higher order and is generally predefined independent of conditions on the control channel (). The device (A) recovers the user data received over the control channel () by demodulating at least the user-data modulation layer (B) at the higher order.
