A device, method and terminal for configuring same-frequency interference cells

Abstract

The purpose of the embodiments of the present invention is to provide a device, method, and terminal for configuring co-channel interference cells. The device includes: a first acquiring module, configured to acquire the first Received signal code power; co-frequency interference cell processing module, used to measure the second received signal code power of each cell in the target neighboring cell under the service time slot, and according to the measurement result of the second received signal code power, from the Selecting some or all of the cells in the target neighboring cell is configured as co-frequency interfering cells for joint detection under the service time slot; wherein, the target neighboring cell is from the first received signal code power in descending order from the Cells selected in the original neighborhood. The present invention can configure co-frequency interference cells under service time slots for TD-SCDMA terminals, and improve the joint detection performance of TD-SCDMA terminals under service time slots.

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
