A user terminal of a radio system arranged to operate a frequency band subdivided into one or more carrier bands, each of which carries a cyclic set of consecutive time slot. The user terminal comprises a first receiver part adjustable to a defined carrier band, and a second receiver part adjustable to a defined carrier band; wherein the first and the second receiver parts are separately operable. The user terminal comprises also allocation means for allocating to a radio channel at least a first timeslot and a second timeslot, wherein the first timeslot and the second timeslot may belong to different carrier bands. The first receiver part and the second receiver part are adjusted to the carrier bands of the first timeslot and of the second timeslot according to a predetermined scheme. The invented structure improved data throughput of the transmission by providing improved quality of transmission through diversity and added capacity through the multicarrier operation.
