A.63 Monitoring of beam switches

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

Beam is an important feature in 5G networks. In case the intra-beam switch function is enabled (see TS 38.331 [20]), due to the complexity of the radio environment, especially when UE moves quickly and frequently, it is possible to have problems such as pointing deviation, which can lead to switch failure. The success rate of beam switch can help to reflect whether there is a problem in beam related parameter configuration. Furthermore, low beam switch success rate will impact user experience. Therefore, it is essential in network operations to monitor the success rate of beam switch and to define the related measurements.
