Abstract

The invention relates to a signal sampling method and device, relay equipment and a storage medium. The relay equipment receives a radio frequency signal sent by a host base station within a preset beam scanning range; performing down-conversion processing on the radio frequency signal received at the first scanning angle in the beam scanning range to obtain a down-conversion signal at the first scanning angle; filtering the down-conversion signal by using a filter to obtain a narrowband signal corresponding to the down-conversion signal, wherein the filtering bandwidth of the filter is smaller than the bandwidth of the down-conversion signal; and performing sampling processing on the narrowband signal by using a sampler to obtain a sampling signal of the narrowband signal, wherein the sampling bandwidth of the sampling device is matched with the filtering bandwidth of the filter and is smaller than the bandwidth of the down-conversion signal. By adopting the method, the cost of the relay equipment can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a signal sampling method, device, relay device and storage medium. Background technique [0002] With the development of 5G communication technology, in order to overcome the shortage of sub-6G spectrum resources, based on the large bandwidth characteristics of millimeter wave, millimeter wave communication is usually used on the market. However, in the 5G millimeter wave frequency band, the space loss of electromagnetic wave signals is large, the propagation path is short, and the penetration ability is poor. The problem of mmWave coverage loss in non-line-of-sight transmission scenarios (Not Line of Sight, NLOS for short). The basic function of the relay device is to amplify the signal of the host base station and forward it to the user equipment. It is an auxiliary device in the communication system. Its advantage is that in some scenarios, the networking...
