  • New event trigger H1/H2 is introduced, which intends to trigger measurement report when a flying height of UAV UE is higher or lower than a threshold.
  • the measurement related parameters can be configured per height range in one configuration, and multiple values associated to multiple height range can be configured simultaneously.
  • This feature intends to reduce the signaling overhead and latency for radiso resource control (RRC) reconfiguration based on UE’s height report, which further decreases the caused interference by corresponding signaling.
  • RRC radiso resource control
  • a parameter ssb-tomeasure can be configured per height range, which controls UE to measure configured Synchronization Signal and PBCH Blocks (SSBs) other than all SSBs.
  • SSBs Synchronization Signal and PBCH Blocks
  • the threshold for event A3/A4/A5 can be configured per height range, as well as another parameter numberoftriggeringcells. The purpose of numberoftriggeringcells is for interference detection, and when configured such parameter, measurement report will be triggered after multiple cells fulfills the reporting condition instead of one cell fulfills the condition, thus avoid too frequently measurement reporting and reduce the signaling and interference.
  • ssb-tomeasure when ssb-tomeasure is configured, UE only measures configured SSBs, while when numberoftriggeringcells is configured, UE may need to (expected by NW) measure all SSBs. Since ssb-tomeasure is in MO configuration while numberoftriggeringcells is in MR configuration, two parameters can be configured together and even for the same or overlapped height range. When both are configured together, UE can only measure ssb-tomeasure, which will cause inaccurate interference measurement results. It was proposed to ignore ssb-tomeasure whenever numberoftriggeringcells is configured, i.e. when numberoftriggeringcells is configured, UE always measure all SSBs in order to have accurate interference results. However, this means configured ssb-tomeasure no longer take effect in all cases, thus cannot utilize the advantage of ssb-tomeasure e.g. mobility optimization.
  • UE may receive from a network entity two height dependent parameters: a first parameter indicative of at least one SSB to measure for a first height range and a second parameter indicative of a number of cells for triggering measurement reporting for a second height range.
  • the UE may ignore one of the two height dependent parameters conditionally. Note that “ignoring” one of the two parameters also means “prioritizing” the other parameter. As a result, UE will follow “prioritized” parameter and determine “ignored” parameters as invalid.

Abstract

Divers aspects de la présente divulgation concernent un UE, un processeur pour une communication sans fil, une entité de réseau, des procédés et un support lisible par ordinateur pour une mesure dépendant de la hauteur. L'UE reçoit, en provenance d'une entité de réseau, un premier paramètre indicatif d'au moins un SSB à mesurer pour une première plage de hauteurs et un second paramètre indicatif d'un nombre de cellules pour déclencher un rapport de mesure pour une seconde plage de hauteurs. L'UE ignore de plus l'un du premier paramètre et du second paramètre, de manière conditionnelle. De cette manière, les performances d'un système de communication sans fil peuvent être améliorées selon les besoins pour des scénarios spécifiques.
