When in a high speed environment, the UE may use more radio time for each intra-frequency measurement occasion to get more accurate information on present conditions (alternative to relaxing requirements). During a measurement occasion, the UE may obtain a snapshot which may contain multiple non-coherent samples.
When in a high speed environment, the UE may modify thresholds for radio link monitoring (RLM). The RLM thresholds include an in-sync threshold (Qin) and an out-of-sync threshold (Qout). The UE regularly compares the DL radio quality of the UE's serving cell with the pre-defined RLM thresholds to determine whether the UE is in sync or out of sync with respect to the serving cell. Currently Qin and Qout are expressed as 2% and 10% of hypothetical BLER (Block Error Rate) of PDCCH respectively. It may be pre-defined that when operating in HSVN, the UE may use different values of Qin and Qout compared to the values used under normal operation. Under HSVN, for example, the UE may be required to use Qin and Qout corresponding to 4% and 12% of hypothetical BLER of PDCCH respectively. This may reduce instances of the UE going into out of sync too early at higher speed and may increase the time that the UE will stay in sync.
