Abstract: Aspects are provided which allow a UE to apply new radio high-speed train mode determination and false alarm suppression in HST deployments. The UE combines a plurality of indications associated with a high-speed train (HST) mode detection into a consolidated HST mode configuration signal. The UE determines whether to suppress the consolidated HST mode configuration signal based on a mobility metric of the UE and a plurality of thresholds. The UE transitions into a HST mode when the consolidated HST mode configuration signal is not suppressed based on the mobility metric of the UE exceeding at least one of the plurality of thresholds. As a result, false HST mode flags may be avoided and HST mode detection success rates may thereby be improved.

The UE may input UE history data or crowdsourced data (e.g., from a local network or a cloud-based server) into the ML model to generate a predicted gain state which may be more likely to result in a successful initial acquisition (e.g., without reattempting the initial acquisition procedure). The UE may use the initial gain state generated by the ML model to attempt an initial acquisition procedure with a network entity.
