Abstract

The present invention relates to the field of mobile communication technology, and in particular to a method and device for selecting a wireless transmission path. In this solution, the CQI of each wireless transmission path is determined according to the corresponding precoding information, and / or any transmission candidate node set The orthogonality information of the channel propagation direction from the two transmission candidate nodes to the wireless transmission path selection node, and the precoding information and the orthogonality information of the channel propagation direction are related to the spatial beamforming. Therefore, when selecting the wireless transmission path , taking into account the interference of the spatial beamforming on the signal, therefore, the accuracy of the determined wireless transmission path is improved, and the utilization rate of capacity resources is improved.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method and device for selecting a wireless transmission path. Background technique [0002] In the network evolution process of 3GPP (3rd Generation Partnership Project) LTE (LongTerm Evolution) or LTE-A (LTE-advanced, advanced long-term evolution) systems, it has shown a shift from homogeneous networks to The trend of heterogeneous network evolution. [0003] In order to increase the capacity of network coverage, heterogeneous networks add small-site nodes on the basis of the coverage of macro-site nodes. With the increasing demand for capacity, small-site nodes are showing a trend of intensive deployment. However, intensive deployment requires overcoming The data of the station node is transmitted to the CN (Core Network). [0004] At present, small station nodes in heterogeneous networks can be connected to ideal backhaul nodes through wireless transmission (f...
