Problems solved by technology

[0004] However, in the process of cell reselection or handover, the terminal cannot obtain the information of the same-frequency interfering cell of the target cell because it has not obtained the neighbor cell relationship information of the target cell from the network side.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] The purpose of the present invention is to provide a method for the terminal to obtain the same-frequency interference cell information of the target cell during the reselection or handover process. The terminal can implement the present invention in the following manner:

[0020] I. During the process of staying in the original cell, the terminal obtains the information of the adjacent cells of the original cell, and periodically performs RSCP measurement on these adjacent cells; the terminal also needs to sort these measurement results to obtain information on several co-frequency interference cells of the original cell;

[0021] Before cell reselection or handover occurs, the terminal needs to retain the latest RSCP measurement results of all measured RSCP cells on the original cell;

[0022] II. In the process of reselection or handover, if the terminal ha...

Abstract

The invention discloses a method used to detect same frequency interference cell during reselection or switching. The method comprises the following steps: a terminal which resides in a home cell periodically detects the measurement result of the received signal code power in an adjacent cell; if the terminal needs to carry out cell reselection or judges according to a network side command that cell switching is needed to carry out, the terminal retains the up to date measurement result of the received signal code power (RSCP) in the home cell; finally, all cells in the home cell sequenced according to an RSCP value are taken as the adjacent cells used for reselecting or switching an object cell.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to the technology of TD-SCDMA terminal co-channel interference elimination in the third-generation mobile communication technology, specifically a method for detecting co-frequency interfering cells in the process of TD-SCDMA terminal reselection or handover. Background technique [0002] In order to improve spectrum utilization and system capacity, TD-SCDMA adopts the same-frequency networking scheme of N frequency points. Although the same-frequency networking solution improves spectrum utilization and system capacity, it introduces same-frequency interference to the downlink tasks of terminals. [0003] In the existing technology, the terminal can obtain the neighbor cell relationship information of the serving cell through the system message or the measurement control message sent by the network, thereby obtaining the information of the same-frequency interfering cell of the se...
