Problems solved by technology

[0003] The disadvantage of this method is that when the UE (User Equipment, user equipment) in the serving cell is relatively concentrated and concentrated in certain areas, such as figure 2 As shown, when generating HII information, almost all neighboring cells receive the same HII information
In fact, each neighboring cell only receives uplink interference from some UEs, so the information received by HII is inaccurate, resulting in poor interference suppression effect

application example 1

[0061] The networking of this application example is as follows: figure 1 As shown, 4 UEs are connected to Cell0, and the positions of the UEs are as follows Figure 6 As shown in: three UEs are located at the edge of Cell0, and one UE is located at the center of Cell0;

[0062] Such as Figure 5 As shown, the high-noise alerting methods for this application example include:

[0063] Step S100, receiving a UE measurement report;

[0064] Step S101, grouping the UEs according to the measurement report reported by the UEs:

[0065] Specifically, the measurement reports of all UEs can be traversed, and for a certain UE, it is assumed that the measured value RSRP of the current serving cell is R s , the measured value RSRP of neighboring cell i is R ni , if R s -R ni 1 , then it is considered that the UE will cause interference to the neighboring cell i at this location, and the neighboring cell is used as one of the high interference indicator target cells of the UE. On th...

application example 2

[0072] The networking of this application example is as follows: figure 1 As shown, 4 UEs are connected to Cell0, and the positions of the UEs are as follows Figure 7 As shown in: three UEs are located at the edge of Cell0.

[0073] The high noise alert method of this application example also Figure 5 As shown, the difference from application example 1 is that when UEs are grouped according to the measurement report reported by the UE, the measurement value used is SINR (Signal to Interference plus Noise Ratio, Signal to Interference plus Noise Ratio) in the measurement report. Other content will not be repeated.

Abstract

The invention provides a method and system for generating high-interference indication information as well as a corresponding sending method and system. According to the measurement report reported by UE (user equipment), the UE in a service cell is divided into one or multiple UE groups; the high-interference indication information of each UE group is generated; and the high-interference indication information of each UE group is sent to the target cell maintained by the UE group. The corresponding system comprises a dividing device, a generating device and a sending device. According to the invention, the same frequency interference among uplink cells can be eliminated effectively.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for generating high interference indication information and a corresponding sending method and system. Background technique [0002] In the current LTE (Long-Term Evolution, long-term evolution) system, most of the same frequency networking, the networking mode see figure 1 .In order to prevent co-channel interference, in the Release 8 protocol, the Load Information specified by 3GPP is used to exchange interference information between different cells. Among them, HII (High Interference Information, High Interference Indication) is an important parameter for exchanging uplink interference information with neighboring cells. The detailed information of this parameter includes two parts: bitmap and target cell. The serving cell sends the bitmap that may cause interference to the cell (target Cell) that may interfere. When generating these parameter...
