Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The main idea of ​​the present invention is that after the serving base station receives the ICIC message (HII, OI or downlink power indication message) of other base stations, the ICIC message carries the interfered PRB or the PRB with higher transmission power, and the serving base station sends a measurement control The message is sent to the terminal, which contains the information of the adjacent cell and the reporting conditions. When the terminal detects that the signal quality of the adjacent cell meets the reporting conditions, it reports the measurement report to the base station. After the base station receives it, it judges that the terminal interferes with other base stations and performs ICIC control. .

[0029] The present invention proposes...

Abstract

The invention provides a measurement control method, which comprises that: a service base station transmits a measurement control message to a terminal, and the message comprises information of an adjacent cell to be measured and a report condition; and the terminal measures signal quality of the adjacent cell, when the signal quality of the adjacent cell meets the report condition, a measurement report is reported to the service base station, and the measurement report comprises physical identification of the adjacent cell measured by the terminal. Through the method, the base station side can acquire accurate information reported by the terminal and the position information of the terminal so as to know interfering terminals and perform intercell interference coordinating treatment.

Description

technical field [0001] The present invention relates to a mobile communication system, and more specifically, the present invention relates to a measurement control method in LTE. Background technique [0002] The purpose of ICIC (Inter-Cell Interference Coordination, inter-cell interference coordination) in the LTE (Long Term Evolution, long-term evolution) system is to effectively reduce the uplink interference to the base station and the downlink interference to the terminal. [0003] The principle of uplink ICIC is as follows: figure 1 As shown, due to the uplink signal transmission of the terminal 1 of the home base station 1, some uplink PRBs (Physical Resource Blocks, Physical Resource Blocks) of the base station 2, such as PRB A, cause interference, resulting in the deterioration of the signal-to-interference ratio on the base station side. To this end, base station 2 informs base station 1 that its uplink PRB A has been interfered by terminals belonging to other ce...
