  • the location where the WUS is sent may be protocol specific. For example, UE1 to UE6 associated with PO0 will wake up at the specified offset position before PO0. If WUS is received, it means that the access network device will send a paging message at PO0, and UE1 to UE6 will wake up at PO0. to receive paging messages. If no WUS is received at the specified offset position before PO0, UE1 to UE6 can stay dormant at PO0 without waking up to listen for paging, thereby saving power consumption.
  • WUS also brought about the problem of false alarms. For example, if the network side device needs to page UE1, but does not page UE2 to UE6, the network side device will also send WUS at the offset position specified before PO0. In this case, the WUS makes a false alarm to UE2 to UE6, so that UE2 to UE6 need to wake up at PO0 even if they are not paged, which wastes the power consumption of UE2 to UE6. To this end, the concept of Group Wake Up Signal (GWUS) was introduced. The GWUS is used to indicate which groups of end devices have paging messages at the associated PO.

Therefore, the network side device can issue the GWUS corresponding to WUS group1 at the offset position specified before PO0.

Abstract

Selon des modes de réalisation, la présente invention concerne un procédé de radiorecherche, un appareil de communication et un support de stockage lisible par ordinateur, se rapportant au domaine technique des communications et susceptibles de réduire la consommation d'énergie d'un dispositif terminal. Le procédé de radiorecherche comprend les étapes suivantes : un dispositif terminal reçoit des premières informations d'indication en provenance d'un dispositif côté réseau ; lorsque les premières informations d'indication indiquent qu'un message de radiorecherche reçu par le dispositif terminal dans un cycle eDRX ne contient pas un identifiant du dispositif terminal, le dispositif terminal reste dans un état de sommeil au niveau d'au moins une PO associée au dispositif terminal dans le cycle eDRX ; et lorsque le message de radiorecherche reçu ne contient pas l'identifiant du dispositif terminal, le dispositif terminal peut rester dans l'état de sommeil au niveau de la ou des PO associées au dispositif terminal dans le cycle eDRX selon les premières informations d'indication. Sur la base des premières informations d'indication délivrées par le dispositif côté réseau, si le dispositif terminal n'est pas recherché, le dispositif terminal peut rester dans un état de sommeil au niveau de la ou des PO associées sans se réveiller pour recevoir le message de radiorecherche, ce qui permet de réduire la consommation d'énergie du dispositif terminal.
