Definitions

  • a subframe may refer to a duration of 1ms. Multiple subframes or slots may be grouped together to form a single frame or radio frame. Of course, these definitions are not required, and any suitable scheme for organizing waveforms may be utilized, and various time divisions of the waveform may have any suitable duration.
  • the various REs 306 within an RB 308 may be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc.
  • Other REs 306 within the RB 308 may also carry pilots or reference signals. These pilots or reference signals may provide for a receiving device to perform channel estimation of the corresponding channel, which may enable coherent demodulation/detection of the control and/or data channels within the RB 308.
  • Some exemplary 3GPP measurement events are event A3, event A4, and event A5.
  • Event A3 is triggered when the measurement result indicates that the signal quality (e.g., RSRP) of a neighbor cell becomes better than the serving cell by a predetermined offset amount.
  • Event A4 is triggered when the measurement result indicates that a neighbor cell becomes better than a predetermined threshold (e.g., RSRP) .
  • Event A5 is triggered when the measurement result indicates that the serving cell becomes worse than a first threshold and a neighbor cell becomes better than a second threshold.
  • the scheduling entity can determine a capability of a UE (e.g., UE 406 or UE 408) that is camped on the anchor cell using a first RAT.
  • the handover circuit 540 may provide the means for determining the capability of the UE.
  • the anchor cell in coordination with a secondary cell (e.g., 5G cell) , supports an EN-DC configuration using the first RAT (e.g., LTE) and a second RAT (NR) .
  • the second RAT has a higher maximum data communication bandwidth or throughput than the first RAT.

Abstract

Des aspects de la présente divulgation concernent un système, un appareil et un procédé pour améliorer la sélection de cellule et l'utilisation de ressources dans un réseau sans fil à l'aide d'une connectivité double telle qu'une connectivité double nouvelle radio E-UTRAN (EN-DC). Dans un réseau déployé en EN-DC, une station de base LTE peut servir d'ancrage pour une cellule activée par 5G. Un équipement utilisateur peut préférer une cellule non activée par 5G plutôt qu'une cellule activée par 5G pendant une resélection de cellule et/ou des événements de transfert intercellulaire de telle sorte que l'utilisation et/ou le chargement de ressources des cellules peuvent être améliorés.
