Same frequency interference cell configuration device, method and terminal

Abstract

The embodiment of the invention aims to provide a same frequency interference cell configuration device, a method and a terminal. The device comprises a first acquisition module which is used for acquiring first received signal code power of an original neighbor area of the terminal in zero time slot, and a same frequency interference cell processing module which is used for measuring second received signal code power of each cell in a target neighbor area in business time slot, and selecting partial or all cells from the target neighbor area for the configuration of a same frequency interference cell used for joint detection in business time slot according to a measurement result of the second received signal code power. The target neighbor area is a cell selected from the original neighbor area according to the first received signal code power from high to low. According to the invention, the same frequency interference cell can be configured for the TD-SCDMA terminal in business time slot, and the joint detection performance of the TD-SCDMA terminal in business time slot is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a device, method and terminal for configuring co-frequency interference cells. Background technique [0002] In the initial stage of TD-SCDMA test network construction, because of the single-frequency co-frequency networking of the whole network, the co-frequency interference of the whole network is very serious, and the network performance is very poor. [0003] The current TD-SCDMA network adopts N-frequency point networking, and the TD-SCDMA terminal uses the zero-slot received signal code power value to detect the signal strength of the surrounding TD-SCDMA cells. Frequency interference mainly depends on whether there are other cells performing services on the same operating frequency in its service time slot, so the terminal cannot predict the same-frequency interfering cell in the service time slot based on the measurement of the received signal code power value of the zer...

[0002] In the initial stage of TD-SCDMA test network construction, because of the single-frequency point and the whole network with the same frequency network, the same frequency interference of the whole network is very serious, and the network performance is very poor.

[0003] The current TD-SCDMA network adopts N-frequency point networking, and the TD-SCDMA terminal uses the zero-slot received signal code power value to detect the signal strength of the surrounding TD-SCDMA cells. Frequency interference mainly depends on whether there are other cells performing business on the same working frequency in its business time slot, so the terminal cannot predict the co-frequency interfering cell of the business time slot based on the measurement of the received signal code power value of the zero time slot
