Embodiment Construction
[0074] According to the received neighbor cell list reported by the cell, the embodiment of the present invention divides all the cells reporting the neighbor cell list into at least one neighbor cell set, wherein any two cells in the neighbor cell set are neighbor cells to each other; Determine the frequency band number corresponding to the cell in at least one neighboring cell set that has not been assigned a frequency band number. Wherein, any two cells in each neighboring cell set have different frequency band numbers, and the frequency band number is used to identify whether the frequency band number will be available according to the number of frequency bands The allocated frequency bands are equally divided into sub-frequency bands obtained; for one of the cells, according to the determined number of the frequency band and the number of the frequency band segments, information capable of determining the position of the primary sub-carrier is delivered to the cell. Since t...

The invention discloses a frequency band configuration method and device. The frequency band configuration method and device aim at solving the problem that a method for configuring frequency bands for neighbor cells in the prior art cannot ensure that frequency bands occupied by main subcarriers of all neighbor cells are mutually orthogonal and call performance of edge users of the cells and the handling capacity of a whole system. The frequency band configuration method comprises the steps: cells of all reported neighbor cell lists are divided into at least one mutually neighbor cell set according to received neighbor cell lists reported by cells, wherein any two cells in the mutually neighbor cell set are neighbor cells; frequency band numbers corresponding to cells which are not allocated with frequency band numbers in at least one mutually neighbor cell set are determined; information for determining the positions of the main subcarriers is issued to one cell according to the determined frequency band numbers and the number of frequency bands. By means of the method, it can be ensured that the frequency bands occupied by the main subcarriers of all neighbor cells are mutually orthogonal and the call performance of edge users of the cells and the handling capacity of the whole system.
Description
Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method and equipment for configuring frequency bands. Background technique [0002] LTE (Long Term Evolution, Long Term Evolution) system uses OFDMA (Orthogonal Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access) technology as the transmission method for downlink, and SC-FDMA (Single-carrier Frequency Division Multiple Access) for uplink. Multiple access) technology as the transmission method. Because the multiple access technology used in the uplink and the downlink takes advantage of the orthogonality between frequencies, theoretically, users in this cell do not interfere with each other. The interference received by all users in this cell mainly comes from other adjacent cells that use the same frequency resources, especially the edge users of this cell, and the same frequency interference from adjacent cells is particularly...
