Abstract

The embodiment of the application provides a random access method and a random access device based on an LTE (long-term evolution) system. The method comprises the steps of: extracting a time domain signal of a random access channel; carrying out spectrum flitting processing on the time domain signal, wherein the spectrum flitting processing comprises calculating spectrum flitting quantity of the time domain signal according to a recursion formula; the spectrum flitting quantity is a complex number comprising a real part and an imaginary part, and achieving random accessing based on the time domain signal after spectrum flitting processing. The embodiment of the application also provides the random access device based on the LTE system. According to the technical scheme, the resource is saved, and the random access efficiency is improved.

Description

technical field [0001] The present application relates to the field of LTE system technology, in particular to a random access method based on the LTE system and a corresponding device. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system is an emerging technology in the field of mobile communication technology, and it is a long-term evolution project under 3GPP (The 3rd Generation Partnership Project, third generation partnership project). Under the trend of "broadbandization" of mobile communication, the LTE system adopts a large number of "quasi-4G" technologies that exceed 3G technologies. Compared with the LTE system UTRAN, it has high data transmission efficiency and low transmission delay, and has become a popular wireless communication technology. [0003] Random access based on the LTE system is a necessary process before UE (User Equipment, user equipment) communicates with the LTE system network, and is used to complete tasks su...
