Signal processing method, computer device, and computer readable storage medium

Abstract

Embodiments of the invention provide a signal processing method, a computer device, and a computer readable storage medium. The method comprises: acquiring k electromagnetic waves carrying a synchronization signal, wherein k is a number of areas obtained by equally dividing a horizontal coverage of a base station, and the electromagnetic waves have the same beam width and different propagation directions; and in the same radio frame, transmitting an electromagnetic wave to each area, so that the UE in the area receives the electromagnetic wave and synchronizes according to the synchronizationsignal. The method provided by the embodiments of the invention divides the horizontal coverage of the base station into areas, and in the same radio frame, transmits an electromagnetic wave carryinga synchronization signal to each area, and the multi-beam scanning method reduces the scanning range, thereby shortening the scanning period, and further shortening the delay in acquiring the synchronization signal by the UE.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal processing method, computer equipment, and a computer-readable storage medium. Background technique [0002] The antenna of the base station is directional. For omnidirectional coverage and suitable for various occasions, two or more single antennas working at the same frequency are fed and spatially arranged according to certain requirements to form an antenna array. The antenna radiating elements of an antenna array are called array elements. [0003] The wave beam is the shape formed on the surface of the earth by the electromagnetic wave emitted by the antenna, and the shape of the waveform can be determined by the transmitting antenna based on beamforming (Beamforming). [0004] Specifically, beamforming is a signal preprocessing technology based on an antenna array. The receiving end of the base station processes the signal, and...

AI Technical Summary

Problems solved by technology

[0012] Since one beam is sent in one wireless frame (10ms), it is understandable that the scanning speed of the antenna beam is limited by the wireless frame duration. If the UE has missed a beam scanning opportunity and has not captured a synchronization signal, it has to wait until the base station once After the scan is completed, the synchronization signal can only be obtained when the location is scanned next time. It can be seen that the UE may have a long waiting time to obtain the synchronization signal, which usually cannot meet the requirements of fast access

[0013] At present, there is no corresponding method in the prior art to solve the problem of delay in obtaining synchronization signals by the UE
