A method and device for sharing spectrum resources

Abstract

The invention discloses a method and device for sharing frequency spectrum resources, which are used to solve the problems of high network construction cost and easy communication blockage in a TD-LTE system. The method is as follows: pre-configure the working frequency band for the base station in the authorized frequency band of the wireless TV signal supported by the RRU device, after the cell is activated, detect whether there is a wireless TV signal in the current working frequency band, and when it is determined that there is a wireless TV signal, start from the current Among the working frequency bands, the working frequency band occupied by the wireless TV signal is screened out, and spectrum resources are allocated to the UE based on the idle frequency bands in the current working frequency band except the working frequency band occupied by the wireless TV signal. In this way, the base station can not only use the authorized low frequency band of the wireless TV system to complete business communication with the UE without affecting the transmission of wireless TV signals, thereby improving spectrum utilization and reducing communication congestion, but also increasing coverage , reducing the cost of network construction.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for sharing frequency spectrum resources. Background technique [0002] Time Division Long Term Evolution (TD-LTE) system has become a research hotspot in the field of mobile communication due to its advantages of small network delay, high data rate and strong anti-interference ability. [0003] In the prior art, the TD-LTE system uses F and D dual frequency bands to realize service communication between user equipment (User Equipment, UE) and the base station, wherein the F frequency band is generally 1850MHz-1990MHz, and the D frequency band is generally 2010MHz- 2620MHz. Although the TD-LTE system has a high data rate and strong anti-interference ability, due to the small coverage area of ​​the TD-LTE system, if you want to achieve wide coverage of TD-LTE in remote mountainous areas, you need to build multiple base stations to achieve ...
