FIELD: wireless communication equipment.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. Wireless communication systems are configured to transmit a preamble signal of random access. Wireless communication device, in particular, is configured to generate a preamble signal of random access, which contains a plurality of groups of symbols, wherein each group of symbols on one tone during a different time resource, in accordance with a frequency hopping pattern, which discontinuously changes the random access preamble signal to a fixed frequency distance in one or more symbol groups and abruptly changes random access preamble signal to pseudo-random frequency distance in one or more other groups of symbols. Each group of symbols contains one or more symbols. Wireless communication device is also configured to transmit a preamble signal of random access.
EFFECT: high throughput and reliability of communication.
