Abstract

The embodiment of the invention provides a method and system for determining an in-band blocking index. The method comprises the following steps: based on a free space propagation model, calculating free space loss MCL between a first base station and a second base station according to the frequency of a transmitting signal of the first base station and the horizontal distance between the first base station and the second base station; according to the maximum transmitting power of the first base station and the free space loss MCL, calculating the interference power when the transmitting signal of the first base station reaches the second base station; and taking the interference power as an in-band blocking index of the second base station. According to the in-band blocking index determination method and system provided by the embodiment of the invention, the objective and reasonable in-band blocking index determination method for the common station address of the base station is provided under the conditions of shortage of frequency resources and dense station addresses of a plurality of base stations at present, so that the anti-blocking capability of the base station under thecommon station address scene of the base station can be truly reflected.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and system for determining an in-band congestion index. Background technique [0002] The in-band blocking index of the base station is defined as: when there is an interference signal with a certain power inside and outside the working frequency band of the useful signal, the correct receiving ability of the base station to the useful signal is tested. According to the 3GPP radio frequency consistency agreement, at present, the in-band blocking index of the base station is defined as the anti-blocking capability of the base station under the coexistence of the base station frequency, that is, on the basis of the coexistence of different base station frequencies, it is mainly aimed at the non-coexistence of two base station frequencies. Under site conditions, when the power of the interfering base station reaches -43dBm, the anti-blo...
