  • the present disclosure for example, relates to wireless communication systems, more specifically to techniques for mobility detection for modem parameter selection.
  • Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power).
  • Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE- Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems.

  • the UE may determine, based on the mean values for the beam metrics, second order statistics (e.g., beam variance for the beam metrics). Based on whether the second order statistics for the beam metrics converge, based on whether a detected beam metric converges at zero or a non-zero value, or any combination thereof, the UE may determine a mobility status for the UE.
  • the UE may determine that the UE is stationary, has small Doppler value, has no rotation, etc. If the second order statistics of the beam metrics converge at a non-zero constant, the UE may determine that the UE has a Doppler value, but no rotation.

Abstract

Sont décrits des procédés, systèmes et dispositifs destinés aux communications sans fil. De manière générale, pour déterminer un état de mobilité d'un équipement utilisateur (UE), l'UE peut effectuer un filtrage ou un post-traitement sur un ou plusieurs critères de mesure de faisceau. L'UE peut générer des statistiques de premier ordre des critères de mesure de faisceau et peut utiliser les statistiques de premier ordre pour générer des statistiques de second ordre. Sur la base du fait de savoir si les statistiques de second ordre des critères de mesure de faisceau convergent, sur la base du fait de savoir si un critère de mesure de faisceau détecté converge à zéro ou une valeur non nulle, ou toute combinaison de ces derniers, l'UE peut déterminer un état de mobilité de l'UE. L'UE peut sélectionner des valeurs de paramètres de gestion de faisceaux appropriées sur la base de l'état de mobilité déterminé.
