Abstract

The invention discloses a frequency spectrum resource sharing method and device, and is used for solving the problems of high networking cost and blocking of communication of a TD-LTE system. The method comprises the steps that the working frequency band is configured for a base station in the authorized frequency band of radio television signals supported by an RRU device in advance, whether the radio television signals exist in the current working frequency band is detected after the cell is activated, the working frequency band occupied by the radio television signals is selected out of the current working frequency band in a screening way when existence of the radio television signals is determined, and the frequency spectrum resources allocated for the UE based on the idle frequency band apart from the working frequency band occupied by the radio television signals in the current working frequency band. Therefore, service communication with the UE can be completed by the base station by using the authorized low frequency band of a radio television system without influencing transmission of the radio television signals so that the utilization rate of the frequency spectrum can be enhanced, communication blocking can be reduced, the coverage can be increased and the networking cost can be reduced.

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 (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 it. As a result...
