FIELD: radio engineering, communication.
SUBSTANCE: method of transmitting uplink feedback for multiple downlink carriers from user equipment involves receiving multiple downlink carriers, determining an uplink carrier assigned for the feedback for at least one of the multiple downlink carriers, transmitting feedback at that uplink carrier, transmitting a report message on said feedback for said multiple downlink carriers, and determining which carrier from said multiple downlink carriers is priority, if the conflict occurs with the feedback for another different one of said multiple downlink carriers.
EFFECT: facilitating configuration of multichannel feedback, facilitating conventional transmission of one carrier.
