Embodiment Construction

[0049]The present invention provides a method and device for using carrier frequencies. Among the carrier frequencies configured in a cell, a part of the carrier frequencies corresponding to a larger number of times of frequency point multiplexing is determined as secondary carrier frequencies, and the rest are determined as primary carrier frequencies; The primary carrier frequency bears the traffic of the cell, so that the secondary carrier frequency corresponding to the frequency point with a large multiplexing frequency is basically in a non-transmitting state under daily traffic conditions, thereby effectively reducing the frequency reuse degree.

[0050] The method and device provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] see figure 1 , which is a flow chart of the carrier frequency usage method provided by the embodiment of the present invention, specifically including:

Abstract

The invention discloses a carrier frequency applied method and a device thereof. The method comprises the steps as follows: determining the TCH idle channel number of the voice channel in the subdistrict of the selected area, and obtaining the maximum secondary carrier frequency number M in a way that each carrier frequency channel number is divided by the TCH idle channel number; leading the carrier frequencies allocated to the subdistrict except for the set special carrier frequencies to be arrayed in a reusing time method in the selected area according to the corresponding frequency points thereof, and selecting out N carrier frequencies as the secondary carrier frequencies according to the reusing number from big to small; determining the rest carrier frequencies as the first level carrier frequencies after selecting out the secondary carrier frequencies; wherein, the N is less than or equal to the maximum secondary carrier frequency number M; and the first level carrier frequency is preferentially utilized to bear the telephone traffic in the subdistrict. Adopting the method and the device can effectively reduce the frequency reuse degree in the selected area, reduce the in-band frequency interference, and improve the network quality.

Description

technical field [0001] The invention relates to wireless communication, in particular to a method and device for using cell carrier frequency in a wireless communication network. Background technique [0002] Frequency reuse technology refers to the use of the same frequency to cover different areas in a wireless network. These areas using the same frequency need to be separated from each other by a certain same-frequency reuse distance to meet the requirements of suppressing the same-frequency interference to within the allowable index. In the case of limited frequency resources, network capacity can be improved by reusing frequencies and controlling interference. [0003] At present, the network has a large number of base stations and a large station configuration in dense urban areas and traffic hotspots, and there is a huge demand for new station expansion. However, the expansion of the wireless network is largely limited by frequency resources. With more and more netwo...
