NETWORK DEVICE, USER DEVICE AND WAY OF TRANSMISSION OF ACCESS SIGNAL Russian patent published in 2018 - IPC H04W48/16 H04W8/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to a user device and a network node. In the method, user device (10) comprises transceiver (11) configured to broadcast an S_A access signal, when there is no connection with any radio network, receive a response S_R access signal in response to the broadcasting of the S_A access signal, and establish communication with at least one network node of (20a, 20b, ..., 20n) of the radio network. Network node (20) comprises transceiver (21) and processor (22); in which transceiver (21) is configured to receive the broadcast S_A access signal, in which the broadcast S_A access signal contains information about the identifier of user device (10); wherein processor (22) is configured to assign at least one frequency spectrum segment for communication to user device (10); and wherein transceiver (21) is further configured to transmit a response S_R access signal to user device (10).

EFFECT: obtaining access to a radio network through one or more segments of the frequency spectrum and / or radio access technology without prior information of superimposed radio communication systems.
