  • Wireless communications systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts, or other similar types of services. These wireless communications systems may employ multiple-access technologies capable of supporting communications with multiple users by sharing available wireless communications system resources with those users.
  • wireless communications systems have made great technological advancements over many years, challenges still exist. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Accordingly, there is a continuous desire to improve the technical performance of wireless communications systems, including, for example: improving speed and data carrying capacity of communications, improving efficiency of the use of shared communications mediums, reducing power used by transmitters and receivers while performing communications, improving reliability of wireless communications, avoiding redundant transmissions and/or receptions and related processing, improving the coverage area of wireless communications, increasing the number and types of devices that can access wireless communications systems, increasing the ability for different types of devices to intercommunicate, increasing the number and type of wireless communications mediums available for use, increasing the number and type of communication channel subscriptions available for use, and the like.

  • the UE and network may establish these connections, and the UE may later transition to an idle state (e.g., a radio resource control (RRC) idle state) .
  • RRC radio resource control
  • the UE may perform various idle mode procedures for the first and second subscriptions (e.g., neighbor cell measurements, neighbor cell search) .
  • the UE may use the DDS to perform such idle mode procedures for the nDDS.
  • the DDS and nDDS may be configured differently (e.g., a different dedicated configurations, including different frequency priority information) , and the DDS performing idle mode procedures for the nDDS may be inefficient.

  • the UE may use the first subscription to perform idle mode procedures for the first subscription, but select a subscription (e.g., one of the first subscription or the second subscription) to use to perform the one or more idle mode procedures for the second subscription based on a comparison of relative priorities for the first subscription and the second subscription. For example, the UE may compare the first RAT priority to the second RAT priority to determine whether to use the first subscription or the second subscription.

If the DDS supported RAT is higher than or equal to the nDDS support RAT, then the DDS subscription may perform the idle mode activities for nDDS. If a dedicates priority list is present, the DDS and nDDS priorities may be compared, and if the DDS dedicated priority is higher than or equal to the DDS priority, the subscription associated with DDS may be used for the idle mode activities for nDDS.

  • the techniques described herein may allow the UE to keep connections alive for quicker switching back and forth as needed or is optimal. Further, in some aspects, there may be lower latency and/or higher throughput communications because the UE can switch back onto a RAT more quickly or remain longer on a faster connection (e.g., larger bandwidth, larger throughput) . Energy and processing cycles may be conserved, and may enable higher throughput with fewer unnecessary idle mode procedures. Dynamic critical quality of service (QoS) may benefit, for example through increased throughput and/or decreased latency
