Embodiment Construction
[0031] The basic idea of the present invention is to estimate the service quality of the wireless relay node serving the UE at the candidate location (position to be installed) based on the measurement results of the measurement points within the target coverage of the wireless relay node, and the wireless relay node is based on the backhaul link SINR Select the serving macro base station, and comprehensively consider the service quality of the wireless relay node serving the UE on the access side and the system resources occupied by the backhaul side, and select the optimal location for deploying the wireless relay node.
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.
[0033] figure 1 It is a schematic diagram of the application scene of the present invention, such as figure 1 As...

The invention discloses a method for wireless relay node address selection. The method includes that wireless relay nodes are installed at positions, which can meet requirements of bandwidth required for communication of all UE (user equipment) accessing to the wireless relay nodes, and where the maximum signal to interference and noise ratio (SINR) of channels between the wireless relay nodes and macro base stations accessed with the wireless relay nodes is achieved. The invention further discloses a device for wireless relay node address selection. By means of setting multiple measurement points, communication quality and bandwidth requirement of positions of different wireless relay nodes to be installed are detected, wireless link performance of an access side and a return side of the wireless relay nodes are taken into consideration sufficiently, positions occupying smallest system resources are selected for configuring the wireless relay nodes on the premise of guaranteeing service quality of the UE on the access side, and accordingly occupation of the system resources is reduced to the utmost extent on the premise of guaranteeing local coverage performance.
Description
technical field [0001] The invention relates to a site selection technology for a relay station, in particular to a method and device for site selection of a wireless relay node. Background technique [0002] The next-generation mobile communication system needs to be able to bring service levels close to broadband Internet to UEs. The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) organization has begun to formulate (LTE-A, LongTerm Evolution Advanced) standards, in order to meet The requirements of the fourth generation (4G, 4th Generation) mobile communication formulated by the International Telecommunication Union International Telecommunication Union Radiocommunication Sector (ITU-R, Radio Communication Sector of ITU). LTE greatly increases the downlink 1Gbps peak rate and uplink peak rate of 500Mbps, lower UE plane and control plane delays, higher peak and average spectral efficiency, and higher cell edge throughput. [0003] Due to the ...
