Problems solved by technology

[0005] While using FFR technology to effectively suppress co-channel interference, it is very likely that all users are concentrated in a certain zone (zone), while there is no data transmission in another zone, wasting precious frequency resources. The zone here includes zone R1 and Region R3

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0037] The core idea of ​​the present invention is that for the FFR technology, the basis for deciding whether the user uses the outer ring or the inner ring resource is the signal strength, but there are many ways to measure the signal strength, such as the received signal strength indication (Received Signal Strength Indication, RSSI) , Carrier-to-Interference and Noise Ratio (Carrier-to-Interference and Noise Ratio, CINR), what adopt in the present invention is coding modulation scheme (Modulation and Coding Scheme, MCS) and multiple input multiple output (Multiple Input Mu...

Abstract

The invention provides a resource optimization method and device which comprises the steps of: obtaining a modulation coding system (MCS) and a multi-input and multi-output (MIMO) type of a region where a user is in, comparing thresholds corresponding to the MCS and the MIMO type of the region where the user is in, and determining a target region of the user according to a comparing result, wherein the region is an inner ring or outer ring. The invention also provides a resource optimizing device. According to the invention, resource utilization rate can be increased, and downlink throughput capacity of a base station is increased.

Description

technical field [0001] The invention relates to a WiMAX (Worldwide Interoperability for Microwave Access, Worldwide Interoperability for Microwave Access) wireless broadband access network, in particular to a resource optimization method and device. Background technique [0002] WiMAX system is a broadband wireless access system based on IEEE802.16 protocol. The bandwidth resources of WiMAX licenses issued by various countries and regions are different. The direct consequence of the lack of frequency resources is the same-frequency cell interference. How to maximize the use of frequency resources and provide mobile cellular networks with the best capacity and coverage performance is Operators expect solutions from equipment vendors. Frequency reuse technology can meet the requirements of coverage and capacity at the same time, so it has become a commonly used method for suppressing co-channel interference. [0003] Fractional Frequency Reuse (FFR) is a commonly used freque...
