Publication number: 20240080686Abstract: Mechanisms for estimating a ratio of indoor-to-outdoor traffic or user equipment distribution. A method is performed by a network node. The method includes obtaining, for a set of user equipment, radio signal measurements. The radio signal measurements have a probability distribution function. The method includes separating the probability distribution function into a set of clusters. Each cluster has its own individual probability distribution function. The method includes estimating the ratio of indoor-to-outdoor traffic or user equipment distribution by predicting, from the individual probability distribution functions of the clusters, which, if any, of the clusters represent indoor user equipment and which, if any, of the clusters represent outdoor user equipment. The method includes performing a network related action in accordance with the ratio of indoor-to-outdoor traffic or user equipment distribution.Type: ApplicationFiled: February 1, 2021Publication date: March 7, 2024Inventors: Rohit CHANDRA, Brahim BELAOUCHA, Tomas LUNDBORG, Gunther AUER, Bengt MÄLER

Publication number: 20210263128Abstract: Systems and methods for determining an indication of locationing accuracy are disclosed herein. In some embodiments, an antenna deployment including multiple antennas and corresponding locations for the antennas is obtained. Then, one or more radio characteristics are determined for ubiety locations based on the antenna deployment and an indication of locationing accuracy for the ubiety locations is determined based on the one or more radio characteristics. In this way, an antenna deployment can be evaluated for locationing accuracy. This may be used by a network engineer or an automated system to determine and/or refine an antenna deployment.Type: ApplicationFiled: September 14, 2018Publication date: August 26, 2021Inventors: Roland Smith, Gunther Auer, Kunpeng Qi
