    Abstract: Systems and methods for triggering measurements before the completion of connection resumption are provided. In some embodiments, a method performed by a wireless device for performing measurements where a current Radio Resource Control (RRC) status is: IDLE or INACTIVE. The method includes monitoring for a potential reception of a downlink message in a cell that the wireless device is camping on; detecting, based upon the reception of the downlink message, information regarding performing measurements; performing measurements based on the information regarding performing the measurements; and reporting the measurement results. In some embodiments, the message is a paging message or a message multiplexed with the paging message. In this way, latency might be reduced to start performing measurements.

  • Patent number: 11832158
    Abstract: A network node obtains a message to be transmitted as a public warning system notification to multiple UEs, via one or more SIBs, and obtains area information corresponding to the message. The area information indicates an area for which the message is relevant. The network node determines how many SIBs are needed for transmitting the area information and segments the message into a plurality of segments, based on how many SIBs are needed for transmitting the area information. The network node transmits the message and the area information via SIBs, such that a segment of the message is included in each SIB and such that each portion of the area information included in a SIB is accompanied by a segment of the message. A UE receives the SIBs and assembles the message and area information, displaying the message if it is relevant.
