FIELD: radio engineering, communication.SUBSTANCE: invention relates to a radio transmission device and method. The device and the method use a signature table having access types, DL CQI, and signatures uniquely correlated to one another. In this signature table, the DL CQI level is set for each access type in accordance with the data amount transmitted/received before a data transmission start after a transmission of RACH. If the access type is "idle", the data amount is greater compared to other access types and the DL CQI is set to level 1-6. If the access type is "active", the data amount is smaller compared to other access types and the DL CQI is set to smaller than level 3 and greater than level 4. Furthermore, if the access type is "handover", the data amount is middle as compared to other access types and the DL CQI is set to level 1-3 or higher.EFFECT: high efficiency of using resources without increasing or reducing the number of signatures.4 cl, 21 dwg |
