Abstract

The invention relates to the technical field of communication, and provides a random access method which is applied to terminal equipment, the terminal equipment stores a random access configuration table, and the random access configuration table comprises a configuration mode of a time slot number corresponding to a default subcarrier interval. The random access method comprises: searching a synchronization signal block SSB, and receiving a system message SIB1 broadcasted by a base station, the SIB1 comprising an indication parameter for indicating a configuration mode of a time slot number corresponding to a non-default subcarrier interval, the configuration mode of the time slot number corresponding to the non-default subcarrier interval satisfying that a TDD period is matched with a configurable PRACH period; calculating a time domain position for sending the PRACH based on the indication parameter; and based on the time domain position for sending the PRACH, sending the PRACH random access preamble at a sending opportunity RO corresponding to the selected SSB so as to carry out a random access process. According to the invention, configuration and scheduling of the SSB and the PRACH under multi-beam transmission can be realized more conveniently and quickly.

Description

technical field [0001] The present application belongs to the field of communication technologies, and in particular, relates to a random access method, an information broadcasting method, an apparatus, an electronic device, and a computer-readable storage medium. Background technique [0002] At present, in order to meet the exponential growth demand of mobile data transmission, 5G and 5G-A systems are often used in the FR2 high-frequency band (also known as the millimeter-wave band, which has weak diffraction ability, but supports a maximum bandwidth of 400MHz, so its data transmission The rate is much higher than FR1), using more sufficient bandwidth resources to achieve higher transmission rates. [0003] Electromagnetic waves with higher frequencies have the characteristics of large propagation attenuation and short transmission distance. In order to increase the transmission distance, the 5G system discusses technologies such as massive multiple-input multiple-output (...
