Embodiment 1

[0035] In this embodiment, a method for planning micro cell construction is provided, which is applied to a scenario where a micro cell is added to a network covered by a macro cell.

[0036] Such as figure 1 As shown, the planning method for micro-cell construction according to this embodiment includes: step S102, determining the first pilot signal-to-noise ratio parameter of the micro-cell and the first external interference factor when the micro-cell does not perform pilot transmission; step S104, in the case that the micro cell performs pilot transmission, measure the second external interference factor of the micro cell, and compare the first external interference factor with the second external interference factor; step S106, the pilot transmission cannot be performed in the micro cell In the case of , measure the second pilot signal-to-noise ratio parameter of the macro cell, and compare the first pilot signal-to-noise ratio parameter with the second pilot signal-to-noi...

Embodiment 2

[0066] In this embodiment, a method for planning micro cell construction is provided, which is applied to a scenario where a micro cell is added to a network covered by a macro cell.

[0067] Such as Figure 4 As shown, the planning method for micro-cell construction according to this embodiment includes: step S402, obtaining the first external interference factor of the micro-cell according to the predetermined system parameters of the micro-cell when the micro-cell does not perform pilot transmission; step S404, Under the situation that the small cell carries out pilot frequency transmission, measure the second external interference factor of the small cell; Step S406, compare the first external interference factor with the second external interference factor, and judge whether the small cell reaches joining according to the result of the comparison Requirement in networks covered by macro cells.

[0068] Wherein, the first external interference factor is determined by the ...

Abstract

The invention discloses a micro-cell construction planning method, which comprises: determining the first pilot frequency signal to noise ratio parameter of the micro-cell and the first foreign interference factor while the micro-cell does not perform pilot frequency emission; under the condition that the micro-cell performs pilot frequency emission, measuring the second foreign interference factor of the micro-cell, and comparing the first foreign interference factor and the second foreign interference factor; under the condition that the micro-cell does not perform pilot frequency emission, measuring the second pilot frequency signal to noise ratio parameter of the macro-cell, and comparing the first pilot frequency signal to noise ratio parameter and the second pilot frequency signal to noise ratio parameter; and judging whether the micro-cell meets the request of entering the network covered by the macro-cell according to the comparing result. Applying the invention can judge whether the current configuration of the micro-cell meets the predetermined interference requirement when planning to introduce a micro-cell into a macro-cell, thereby, facilitates network planning.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a planning method for construction of a micro cell, which can be applied to the scenario of adding a micro cell to a network covered by a macro cell. Background technique [0002] A traditional cellular network is composed of a macrocell (Macrocell), and the coverage radius of each cell is mostly 0.5km to 25km. Macro cells are generally used in the initial stage of network construction to solve the problem of wide coverage under small traffic. [0003] The coverage radius of a Microcell is about 30m to 1000m, the transmission power is relatively small, and the transmission is mainly carried out along the line of sight of the street, and the signal leakage on the roof is relatively small. Therefore, microcells are often used to increase radio coverage and eliminate "blind spots" in macrocells. The picocell with lower transmission power also exists as a supplementar...
