FIELD: radio engineering, communication.SUBSTANCE: invention relates to wireless communication and can be used for efficient physical uplink control channel resource allocation for carrier aggregation. A base station receives control information from a user terminal in a first set of radio resources at an uplink primary component carrier associated with a first downlink component carrier if the user terminal is scheduled to receive downlink transmission at a first single downlink component carrier, and on a second set of radio resources at an uplink primary component carrier, wherein said resources in the second set are additional radio resources compared to resources in said first set, if the user terminal is scheduled to receive downlink transmission at a second single downlink component carrier or multiple downlink component carriers.EFFECT: facilitating adaptive switching between two sets of different resources depending on downlink allocation.34 cl, 13 dwg |
