FIELD: physics, communications.
SUBSTANCE: invention relates to communication engineering and can be used in radio communication networks. Methods and an apparatus for reconfiguring mappings from carrier indicator field values to component carriers are disclosed. Each CIF value is mapped to a respective component carrier comprising a respective shared data channel. Each respective shared data channel corresponds to at least one downlink control channel carrying said each CIF value. A radio network node 130 reconfigures mappings from CIF values to component carriers, while at least one mapping of CIF value to component carrier is maintained.
EFFECT: high transmission channel throughput.
