Preamble transmission method, apparatus, device, and medium

Abstract

The application discloses a preamble transmission method, device, equipment and medium, and belongs to the communication field. The method is executed by a terminal device, and the method comprises the following steps: a preamble sequence is transmitted, and the preamble sequence is one of a first sequence; wherein the type of the first sequence comprises at least one of the following: an m sequence, a Gold sequence and a Walsh sequence. Through the low-complexity preamble sequence, low-power-consumption random access, uplink synchronization and frequency offset estimation are realized, and the possibility of transmitting a preamble is provided for some communication scenes which are difficult to adopt an OFDM waveform.
