Embodiment Construction

[0071] The present invention will be further described below in conjunction with specific examples.

[0072] A method for inter-cell interference coordination of a millimeter wave cellular network, comprising the following steps:

[0073] Step 1: Information collection and model building

[0074] Step 1.1 Collecting information: According to different sources of information, the process of collecting information by the millimeter wave base station mainly includes two processes: 1) The user feeds back to the base station its service quality requirements for the services initiated, wherein the service quality requirements include the signal-to-interference ratio threshold Requirements θ, transmission reliability requirements ε, average rate requirements, etc. 2) The base station obtains other system information through the network side, including the path loss model Base station density λ b , the main lobe gain G of the antenna array m , side lobe gain G s , half-power bea...

Abstract

The invention discloses an inter-cell interference coordination method of a millimeter wave cellular network, and belongs to the technical field of wireless communication. Firstly, information is collected and a model is established. Secondly, two interference coordination methods are provided, an interference coordination parameter rho is set to be greater than or equal to 1, and information transmission of a neighbor millimeter wave base station identified as a strong interference source on a specified time-frequency resource block is muted; thirdly, interference coordination parameters areselected. The method is based on the information collected in the step 1, the established model and the two interference coordination methods provided in the step 2. The key performance indexes of thecellular users are evaluated based on a random geometry theory, the target performance indexes meet the service quality requirements of the users by adjusting the interference coordination parameters, and the interference coordination parameters suitable for the current target network are determined as preconditions for executing the step 4. And finally, an interference coordination scheme is implemented. The inter-cell interference of the millimeter wave frequency band can be effectively suppressed, the communication service quality of millimeter wave cellular users is ensured, the user burden is reduced, and the load of a backbone network is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for inter-cell interference coordination of a millimeter wave cellular network. Background technique [0002] Compared with the fourth-generation mobile communication network (4G), the peak rate of the fifth-generation mobile communication network (5G) for 2020 needs to be increased by 10 times to 10Gbps, and the user can obtain a rate of 10Mbps, and special user needs can reach 100Mbps. The ability of 5G to achieve such a high data transmission rate is inseparable from the various new technologies and standards behind it. The use of millimeter wave technology is undoubtedly the most critical link. Millimeter wave is an electromagnetic wave with a wavelength between 1-10mm and a frequency between 30-300GHz, which is one of the main frequency bands for 5G communication. At present, 4G spectrum resources are very scarce. As the operator with the most abundan...
