FIELD: wireless communication equipment.
SUBSTANCE: invention relates to wireless communication systems. Method of scheduling uplink configuration to identify a Msg3 terminal by a network node comprises steps of: slot offset, configuration of demodulation reference signal DMRS and initial position for sending message Msg3 by user equipment (UE) of generation 5G. Slot offset depends on subcarrier spacing. Transmission of information signaling in UE may be initiated by UE for scheduling transmission of Msg3 message.
EFFECT: technical result consists in improvement of throughput capacity of system UL uplink, reducing delay of random access.
