Abstract

The invention provides an unlicensed frequency band heterogeneous network embedded friendly coexistence method and system based on spatial multiplexing. The method comprises the steps that a multi-antenna WiFi access point is connected with a plurality of WiFi loads; channel states of the WiFi loads are detected; the occupation of spatial flow by the WiFi loads with relatively poor channel qualityis forcedly disabled; and optimal heterogeneous network loads are searched for to be accessed, and idle spatial resources are occupied: a search process of an optimal heterogeneous network load set as shown in the description is executed. The method and the system are based on the spatial multiplexing technology, so that the performance of WiFi equipment/a user on an unlicensed frequency band isnot obviously lost or even effectively improved, and the friendly coexistence and the win-win effect of the heterogeneous network are realized. Compared with an existing coexistence method, the heterogeneous network coexistence method provided by the invention can effectively improve the performance of the heterogeneous network, and fair distribution of MIMO spatial flow is realized.

Description

Technical field [0001] The invention belongs to the technical field of mobile Internet, and in particular relates to an embedded friendly coexistence method and system for an unlicensed frequency band heterogeneous network based on spatial multiplexing technology. Background technique [0002] With the explosive growth of mobile data traffic, the shortage of spectrum has become the main bottleneck for the next generation of wireless communications. As a frequency band that has no exclusive access rights and can be used by almost anyone and any organization, unlicensed frequency bands are widely used in WiFi, Bluetooth, Zigbee, 5GNR (new radio) and satellites due to their open and easily accessible characteristics. Communication and other applications. In order to improve system capacity and spectrum efficiency, the deployment of heterogeneous networks in unlicensed frequency bands based on spatial multiplexing technology has become an inevitable trend, and the resulting friendly...
