Patent drawing
Patent drawing from the official filing.

This filing describes a way for a phone to receive group data broadcasts, like emergency alerts or live streams, while it is in a low-power 'inactive' state. The phone receives specific instructions on which frequency bands to listen to, allowing it to check for updates without fully waking up its main data connection.

Why it mattersIt could help phones save battery by efficiently handling group messages without maintaining a full, high-power data connection.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present disclosure provides a method ( 200) for multicast broadcast service (MBS) multicast reception in a radio resource control (RRC)_INACTIVE state. The method includes receiving ( 201), by a UE from a network associated with the UE, a frequency resource configuration (multicast-bwp-inactive-config) from a plurality of frequency resource configurations for the MBS multicast reception in the RRC_INACTIVE state. The plurality of frequency resource configurations includes a bandwidth part (BWP) configuration and a common frequency resource (CFR) configuration. The method further includes performing ( 203), by the UE, one activity from a plurality of activities for one or more relevant MBS multicast sessions in the RRC_INACTIVE state, based on the received frequency resource configuration. The plurality of activities includes monitoring a physical downlink control channel (PDCCH) and receiving a physical downlink shared channel (PDSCH) in the RRC_INACTIVE state.
