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 present invention provides an inter-cell interference coordination method and device and a computer storage medium. The method comprises: determining that a cell supports a trunking service; and sending an RBG activation bitmap of the cell to a neighboring cell of the cell through a base station to which the cell belongs, so that an LTE cell in the neighboring cell of the cell performs resource allocation according to the RBG activation bitmap and reference signal receive power (RSRP) information that is reported by a terminal in the LTE cell, so as to avoid inter-cell interference.

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 the RRM (radio resou...
