FIELD: information technology.
SUBSTANCE: preamble transmission is used to send specific information to a base station when the terminal is using a random access channel (RACH) and the base station efficiently allocates radio resources for transmission of data to the terminal in accordance with specific information. The lag time before data transmission by the terminal is reduced and excessive consumption of radio resources is minimised.
EFFECT: reduced excessive consumption of radio resources.
