Abstract

The embodiment of the invention discloses a frequency point searching method, a frequency point searching device and a storage medium, when frequency point searching is carried out, if searched subcarrier intervals of a current frequency band are unknown, PSS related processing is carried out on a group of data received in a searching period for multiple times according to multiple subcarrier intervals, at least two groups of first correlation values of the plurality of frequency points are obtained; and a candidate frequency point set is determined according to the at least two groups of first correlation values of the plurality of frequency points. According to the invention, the method does not need to receive data in a plurality of search periods for PSS related processing, solves a problem that the network search time is prolonged due to the fuzzy subcarrier interval, shortens the frequency point search time on the whole, and improves the cell search efficiency.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a frequency point search method, device and storage medium. Background technique [0002] At present, in the cell search stage, a power-based frequency point search manner is usually used to perform cell search. The specific frequency point search method includes: the communication device will receive signals in the target frequency band, perform power value statistics and power value sorting on the received signals, determine the frequency points corresponding to signals with power values ​​greater than the power threshold value, and then Click to do a neighborhood search. However, this frequency point search method needs to consume more processing resources, and the frequency point search takes a long time, resulting in low cell search efficiency. Contents of the invention [0003] In order to solve the above technical problems, the embodiments of the present appl...
