FIELD: radio engineering, communication.
SUBSTANCE: mobile data transmission network includes one or more network elements providing a wireless access interface for a data transmission device. The wireless access interface provides a lot of data transmission resource elements within the host device bandwidth and includes, within the host device bandwidth, a first unit of data resource elements within the first frequency band for allocation, preferably for devices with reduced capabilities for receiving signals representing data transmitted by the transmitter module within the first bandwidth forming the first virtual carrier, each device with reduced capabilities awns a receiver bandwidth that is greater than or equal to the first frequency band, but less than the band of frequencies of the host device. The data transmission device is configured to transmit to the mobile data transmission network the relative capability of the data transmission device for receiving data through the wireless access interface, a relative capability comprising at least an indicator of the relative bandwidth of the receiver unit for receiving signals within the range of frequencies of the host device, greater than or equal to the first bandwidth, and receive a selection of data transmission resource elements that include resource elements and the data that are beyond the first virtual carrier but within the band of data transmission device, in response to an index of the relative transmission capabilities of the device.
EFFECT: ability to eliminate congestion at the central frequency of data transmission resources in which data transmission devices with minimal bandwidth capabilities should receive data transmission resources for receiving downlink signals.
