message or at least on the same channel only one trigger mechanism is required for both reports if the common trigger is carried by a downlink control channel message this gives a saving in downlink overhead a single set of uplink transmission resources can carry both reports this is likely to be more efficient than sending two separate reports if the trigger is carried by a downlink control channel message then this message can grant the resource for the uplink transmission of both reports in accordance with the first embodiment of the invention a system using lte is provided where the primary station from time to time transmits data packets in the downlink and indicates their presence to the relevant secondary stations by means of a control messages like pdcch messages in addition the secondary stations from time to time transmit data packets in the uplink after requesting resources and then being granted resources via pdcch in order to achieve efficient downlink transmission the primary station requests uplink cqi transmission when needed by setting a corresponding u201c cqi request bit u201d in the pdcch message that is used to grant uplink resource according to the invention the same u201c cqi request bit u201d also requests a report on the status of the secondary station.
