Abstract

The invention provides a random access method. The random access method comprises the steps that the maximum number of preamble sequences is acquired; Generating a random access preamble sequence according to the maximum preamble sequence number and the preamble sequence configuration information; And transmitting the random access preamble sequence on a random access channel. The invention also provides a terminal and base station equipment corresponding to the random access method.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a random access method and equipment thereof. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT, internet of things), unprecedented challenges are brought to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND 2020.TRAFFIC] of the International Telecommunication Union ITU, it can be predicted that by 2020, the growth of mobile traffic will increase by nearly 1,000 times compared to 2010 (4G era), and the number of user equipment connections will also increase. It will exceed 17 billion. As massive IoT devices gradually penetrate into mobile communication networks, the number of connected devices will become even more astonishing. To cope with this unprecedented challenge, the communi...
