The following first briefly describes these two factors:
  • the measurement delay of a single frequency point refers to the time required to meet the performance indicators (such as measurement accuracy) when measuring at different frequencies.

  • the terminal device since measurement resources used for measurement at different frequency points may overlap in time, at this time, if the terminal device wants to measure multiple frequency points at the same time, the terminal device needs to be configured with multiple measurement modules.
  • the number of measurement modules configured in the terminal device is limited, which means that different frequency points can only be performed in a time division manner, and only for all the periods of each measurement resource. Several of the configured frequency points are measured, and the remaining frequency points are left to be measured in subsequent cycles. In this case, the delay index of the inter-frequency measurement needs to be extended correspondingly according to the number of frequency points configured by the network to the terminal device.

Therefore, on the first SMTC window of every 160ms, The timing of measurement must be shared among three frequency points, and each SMTC window of frequency point 4 within every 160ms overlaps with the first SMTC window of frequency point every 160ms. Therefore, the second SMTC window within every 160ms The measurement timing on the SMTC window and the fourth SMTC window need only be shared between these two frequency points. In the prior art, directly using the number of frequency points as the measurement delay scaling factor means that frequency point 3 and frequency point 4 will use the same delay index.

Therefore, for each frequency point, the SMTC window that overlaps with the MG in time in the SMTC window at that frequency point is defined as the available measurement window at that frequency point, and the available measurement window period of the frequency point can be expressed as:

Abstract

Des modes de réalisation de la présente invention concernent un procédé, un dispositif et un support de stockage pour déterminer un retard temporel d'une mesure de fréquence différente, le procédé comprenant les étapes consistant à : obtenir le nombre d'opportunités de mesure d'un premier groupe de points de fréquence dans une période prédéfinie, puis déterminer un facteur de mise à l'échelle de retard temporel de mesure de chaque point de fréquence dans le premier groupe de points de fréquence en fonction du nombre d'opportunités de mesure du premier groupe de points de fréquence dans la période prédéfinie, le nombre de points multifréquences dans le premier groupe de points de fréquence et une période de fenêtre de mesure disponible de chaque point de fréquence dans le premier groupe de points de fréquence, puis combiner le retard temporel de mesure de point de fréquence unique obtenu de chaque point de fréquence dans le premier groupe de points de fréquence pour déterminer un retard temporel de mesure de chaque point de fréquence dans le premier groupe de points de fréquence lors de la mesure de points multifréquences. Dans la solution technique décrite, le dispositif terminal considère la période de fenêtre SMTC sur chaque point de fréquence dans chaque groupe de points de fréquence dans le calcul du facteur de mise à l'échelle de retard de mesure, de sorte que le facteur de mise à l'échelle de retard temporel de mesure calculé soit équitable pour chaque point de fréquence dans chaque groupe de points de fréquence.
