Description

This invention relates to the technology of communications. Compared to conventional 3G and 4G systems, 5G systems can offer wider bandwidth and higher data rates, and can support a wider variety of terminals and vertical services. Therefore, in addition to the conventional telecommunications frequency spectrum, 5G systems will also be deployed in a new frequency spectrum, and the frequencies in this new spectrum are significantly higher than the conventional telecommunications frequency spectrum used by 3G and 4G systems. For example, 5G systems can be deployed in the millimeter-wave band (28 GHz, 38 GHz, 60 GHz and above, etc.). According to the laws of radio signal propagation, the higher the frequency of the carrier in which the signal is located, the more severe the fading encountered during propagation becomes. Therefore, in actual deployments, 5G systems, especially those deployed in the millimeter-wave frequency band, require even more advanced cell coverage improvement technologies than conventional 3G and 4G systems. Thus, the problem that needs to be solved is how to more effectively improve the cell coverage of 5G systems.
