Problems solved by technology

[0004] The trunking system is based on a group as the service object, but at present, the group terminal cannot report the RSRP value of the neighboring cell in time, so accurate and timely frequency band adjustment cannot be performed
In the common network of LTE and the trunking system and the trunking private network, if the RSRP value of the neighboring cell cannot be predicted in time, it will lead to a large RSRP, which will cause inter-cell interference of the effective signal on the RE containing the reference signal, thereby affecting the terminal business service quality

Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0023] In the prior art, when inter-cell interference coordination is performed, interference coordination is realized through RSRP information reported by terminals within the coverage of the cell and related interference information of neighboring cells of the cell. However, since cluster terminals cannot report RSRP information, resulting in To solve the problem that the cells of the cluster terminals within the coverage area cannot perform interference coordination, the embodiments of the present invention aim at the above problems, and provide an interference coordination method and device between cells, by using the configuration information RBG activation bitmap of the cell to Interference coordination between cells is realized, and the problem tha...

Abstract

The invention provides a community interference coordination method and device that includes: determine whether the community supports cluster business; when the community supports cluster business, the base station belongs toThe picture is sent to the neighboring community in the community so that the LTE community in the neighboring community in the community in the community is based on the reference signal receiving power RSRP information reported on the terminal reported by the RBG activation bit and the terminal in the LTE community for resource allocation to avoid the resource allocation to avoidInterference in the community.The technical scheme provided by the present invention is used to use the configuration information RBG activation bit map of the community to achieve interference and coordination of the community, and avoid the problem of interference in the community that affects the quality of the terminal business service.

Description

technical field [0001] The present invention relates to the communication field, in particular to an interference coordination method and device between cells. Background technique [0002] LTE is a long-term evolution project of 3GPP (The3rd Generation Partnership Project, third-generation partnership project), and it is the largest new technology research and development project launched by 3GPP in the past two years. The professional trunking system based on CDMA2000 has been widely used in the past few years. When the CDMA2000 network and LTE network coexist in the future, the trunking system based on the LTE standard will become a development trend. [0003] Common LTE systems are based on co-frequency networking, so how to control co-frequency interference between cells is a topic worth studying. ICIC was introduced in Release 8 / 9 of the 3GPP LTE standard. The basic concept of ICIC is to preserve and control the interference between cells through RRM (radioresource m...
