  • Patent number: 10070336
    Abstract: The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage, e.g. for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to one aspect, the disclosure proposes a method, performed in a wireless device 10, of determining radio coverage. The method comprises obtaining S1 at least one path along which radio condition measurements are to be performed and performing S2 radio condition measurements along the at least one path. The method further comprises determining S3 position estimates, wherein at least some of the position estimates correspond to the radio condition measurements.
    Type: Grant

  • Patent number: 10057802
    Abstract: The present disclosure relates to coverage monitoring and in particular it relates to determining radio coverage using correlated radio condition measurements and position estimates, for example for small cell deployment in a building. The disclosure relates to methods for coverage determination as well as to corresponding devices and computer programs. According to some aspects, the disclosure proposes a method, performed in a node 10, 110 of determining radio coverage of at least one small cell base station in a wireless communications network. The method comprises the steps of obtaining radio condition measurements, wherein a respective first time value is associated to each radio condition measurement.
