METHODS AND DEVICE FOR UPDATING SYSTEM INFORMATION Russian patent published in 2021 - IPC H04W48/08 

FIELD: wireless communication.

SUBSTANCE: invention relates to the field of wireless communication. The technical result is to increase the efficiency of mechanisms for notification and retrieval of updated system information (SI), as well as information of the earthquake and tsunami warning system (ETWS), information of the commercial mobile alert system (CMAS) and / or information of the extended access denial (EAB). In accordance with the claimed invention, a wireless device communicates with a base station using a contiguous subset of physical resources on a first carrier. A method in a wireless device comprises obtaining an indication of a subset of a plurality of paging occurrences during an SI update period that the wireless device is configured to monitor, wherein in response to an upcoming SI update, the base station is configured to report each of the plurality of paging occurrences during the SI modification period and tracking a subset of the plurality of paging cases for notifications of upcoming SI updates.

EFFECT: notification mechanisms efficiency for updated system information increased.
