A method performed by a network node for communicating with a wireless device, the network node being operable in a wireless communication network, the wireless device being associated with a serving beam managed by a radio network node associated with the network node, the method comprising: - obtaining a position of the wireless device, wherein the position of the wireless device is associated with an expected beam, when the serving beam and the expected beam are different from each other thereby resulting in a deviation the method is characterized in comprising: - determining whether the deviation is permanent or temporary by applying statistical filtering and determining whether the result of the statistical filtering meets a predetermined threshold or not, wherein a temporary deviation means that the deviation has not happened enough times for the expected beam to be deemed being at least partially obscured, and wherein a permanent deviation means that the deviation has occurred at least more than once, and wherein the permanent deviation is determined based on previously occurred deviations with respect to the same position, when the deviation is determined to be temporary deviation: storing information about the position of the wireless device, the expected beam and the serving beam, when the deviation is determined to be permanent: issuing a notification to any one of an operator of the wireless communication network, cell planning personnel, a maintenance system, or an Operation, Administration and Maintenance, OAM system indicating that the expected beam is at least partially obscured with respect to transmissions for the wireless device. - obtaining a position of the wireless device, wherein the position of the wireless device is associated with an expected beam, - determining whether the deviation is permanent or temporary by applying statistical filtering and determining whether the result of the statistical filtering meets a predetermined threshold or not, wherein a temporary deviation means that the deviation has not happened enough times for the expected beam to be deemed being at least partially obscured, and wherein a permanent deviation means that the deviation has occurred at least more than once, and wherein the permanent deviation is determined based on previously occurred deviations with respect to the same position, when the deviation is determined to be temporary deviation: storing information about the position of the wireless device, the expected beam and the serving beam, when the deviation is determined to be permanent: issuing a notification to any one of an operator of the wireless communication network, cell planning personnel, a maintenance system, or an Operation, Administration and Maintenance, OAM system indicating that the expected beam is at least partially obscured with respect to transmissions for the wireless device. when the deviation is determined to be temporary deviation: storing information about the position of the wireless device, the expected beam and the serving beam, when the deviation is determined to be permanent: issuing a notification to any one of an operator of the wireless communication network, cell planning personnel, a maintenance system, or an Operation, Administration and Maintenance, OAM system indicating that the expected beam is at least partially obscured with respect to transmissions for the wireless device.
