Problems solved by technology

[0004] Judging the interference of different frequency points only considers the intensity of interference power, but does not consider the influence of other factors. Therefore, this also leads to the fact that the existing frequency point configuration cannot make the cell in the state of the lowest traffic channel interference

Embodiment Construction

[0025] The inventor noticed during the invention process:

[0026] Take the Femto base station in the home base station as an example. On the one hand, the existing schemes only consider the intensity of the interference power in the judgment of the interference situation at different frequencies, and there is no load situation at different frequencies, that is, there are interferences on different frequencies. The probability is high and low.

[0027] figure 1 Select the environment diagram for the frequency point of Femto cell, in figure 1 In the scenario shown, it is assumed that in the same floor, Cell1 to Cell3 select frequency points 1 to 3 respectively.

[0028] According to the existing method, when cell 4 is powered on and initial configuration is performed, the interference level of Cell 4 at different frequencies will be determined according to the reference signals of frequency points 1 to 3. Since Cell1 is far away, according to the judgment of the absolute power of the...

Abstract

Disclosed are a method for selecting a frequency point, an HNB and a device. The method includes: determining the signal interference strength of a target base station at each frequency point and the service loads of the other base stations apart from the target base station at each frequency point; and determining the working frequency point of the target base station according to the signal interference strength of the target base station at each frequency point and the service loads of the other base stations apart from the target base station at each frequency point. The present invention can optimize the frequency selection strategy of the HNB cell and therefore decrease co-channel interference among HNB cells.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a frequency point selection method, home base station and equipment. Background technique [0002] In the existing scheme, in the initial establishment process of the Femto (femtocell base station) of the home base station cell, the P-CCPCH (Primary Common Control Physical Channel, The basic common control physical channel) channel received power, and the frequency with lower received power is considered to have lower interference, so the frequency with the lowest interference will be selected as the frequency for the initial establishment of the Femto cell. [0003] The disadvantages of the existing technology are: [0004] The judgment of the interference situation of different frequency points only considers the intensity of the interference power and does not consider the influence of other factors. Therefore, this also leads to the fact that the existing frequency point c...
