Frequency allocation method, frequency allocation device and base station

Abstract

The invention provides a frequency allocation method, comprising: when detecting that a local district accesses the network initially, obtaining frequency allocation information, find reference signal allocation information and switch state information of each district in the plurality of adjacent districts of the local district; working out disturbance index information at all frequencies which can be allocated by the local district according to the frequency allocation information, the find reference signal allocation information and the switch state information of each district; determining target frequency corresponding to the local district according to the disturbance index information at all frequencies, and using the target frequency as the initial frequency of the local district. Correspondingly, the invention also provides a frequency allocation device. According to the frequency allocation method and device, disturbance status in the network can be more actually reflected, and thereby the most suitable frequency can be selected out from a base station, and meanwhile the problem that the reference information cannot be monitored in a frequency allocation period can be avoided.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a frequency configuration method, a frequency configuration method and a base station. Background technique [0002] In the current wireless communication system, in order to further increase the capacity of the network, the miniaturization of the base station and the densification of the network nodes have become an inevitable choice. In the future, there will even be Ultra Density Network (UDN) deployments, such as deploying hundreds of small base stations within the coverage of a macro base station. In the UDN network, the self-configuration and self-planning of the node frequency of the small base station is an important means to reduce the cost of network construction. [0003] The current base station frequency configuration is generally designed in advance during the network planning stage, and the frequency configuration is performed according to the network p...

AI Technical Summary

Problems solved by technology

If some adjacent small cells are off when a new small base station node enters the network, the new entry node may not be able to receive reference signals from adjacent cells during the frequency configuration period, resulting in frequency configuration problems

In addition, due to the existence of the on / off state, only considering the strength of the reference signal will not fully reflect the interference of the node to the network

[0005] Therefore, a new technical solution is needed, which can avoid the problem that reference information cannot be monitored during frequency configuration, and can more truly reflect the interference situation in the network
