FIELD: radio equipment and communication.

SUBSTANCE: invention relates to the field of radio communication. Master base station configures a secondary discard function in a lower layer of the secondary base station, based on the master discard function in the higher layer of the master base station. Master base station forwards the data packet from the higher layer to the lower of the secondary base station. Secondary discard function of the lower layer at the secondary base station discards the received data packet upon expiry of the secondary timer started by the lower layer upon reception of the data packet from the higher layer at the master base station.
