Description

technical field [0001] The invention belongs to the field of mobile communication systems, and in particular relates to the power saving technology of micro base stations in the mobile communication system. Background technique [0002] In the 5G system, frequency range 1 (abbreviation: FR1) and frequency range 2 (FR2 two frequency bands) are used. The FR2 frequency band belongs to the millimeter wave frequency band, so it is suitable for 5G heterogeneous networking. A 5G dense heterogeneous network generally includes The following parts: macro base station, densely configured micro base station, micro base station control center, relay node, user equipment, etc. The dense deployment of a large number of micro base stations using the FR2 frequency band can support more user equipment and provide higher transmission rates. [0003] From the perspective of power saving, 5G heterogeneous networks mainly have two problems. [0004] (1) The power consumption problem of deployin...

AI Technical Summary

Problems solved by technology

[0005](2) The complexity of wireless coverage

In addition, dense micro base station deployment will lead to a large number of frequency reuse

The 5G dense heterogeneous networking adopts the automatic networking method without strict coverage testing and analysis. During periods of low traffic, if some micro base stations are turned off, the original coverage area may become a coverage blind area.

[0012]Fourth: Micro base station coverage area, in which there is only micro base station wireless coverage and no macro base station coverage

However, the deployment of micro base stations is relatively random. Considering the cost of deployment and maintenance, there is generally no strict network planning process. It is mainly used to supplement the blind spots of macro base stations and provide high-speed data transmission to relieve the pressure of macro base stations.

[0016]Second: According to the principle of mobile network management, for a terminal in idle mode, the network cannot accurately locate the cell where the terminal resides, and can only locate the terminal in the location area, so Even in late-night scenarios with low traffic volume, the Femtocell control center cannot determine which Femtocells can be shut down

However, if it is unreasonable to shut down micro base stations, the number of micro base stations that can be shut down is relatively small, and the best power saving effect of the entire 5G heterogeneous network cannot be achieved.
