FIELD: radio engineering and communication.
SUBSTANCE: invention relates to radio communications. Method carried out in a network device comprises steps of: receiving a random access request message from a terminal device and sending a random access response (RAR) message to the terminal device in response to the random access request message. RAR message has a format depending on the type of the random access request message.
EFFECT: technical result consists in increasing the efficiency of using bandwidth when transmitting RAR.
