Abstract

The various embodiments of the present invention disclose a system and method for multimedia broadcast multicast service (MBMS) operation, the method comprises of receiving, by a User Equipment (UE), a common notification configuration message for a Multi-Cast Control Channel (MCCH) and System Information (SI) change from a network, identifying one or more occasions where MCCH or SI change notification is to be scheduled, configuring, by the UE, a DRX sleep and wake up occasions for the UE based on the scheduling of the MCCH and the SI change notification period, monitoring for MCCH change or SI change notification on Physical Downlink Control Channel PDCCH Format 1C scrambled with M-RNTI on wakeup occasion, determining the change notification based on DCI bits pertaining to SI and/or MCCH of one or more MBMS area, and decoding indicated SI and/or MCCH on PDSCH on CAS sub-frames and/or PMCH channel of respective areas.

Dependent claims

A method for providing multimedia broadcast multicast service (MBMS) operation, the method comprising

receiving, by a User Equipment (UE), a common notification configuration message for a Multi-Cast Control Channel (MCCH) and System Information (SI) change from a network;
identifying one or more scheduled MCCH change notifications or one or more scheduled SI change notifications using one or more parameters received in the common notification configuration message;
configuring, by the UE, DRX sleep occasions and wake up occasions for the UE based on the one or more scheduled MCCH change notifications or the or more scheduled SI change notifications;
monitoring for a MCCH change notification or a SI change notification on a Physical Downlink Control Channel (PDCCH) Format 1C scrambled with a M-RNTI on one of the wake up occasions;
determining the MCCH change notification or the SI change notification based on DCI bits pertaining to SI or a MCCH of one or more MBMS areas;
and
decoding the MCCH change notification or the SI change notification on a PDSCH of CAS sub-frames or a PMCH channel.
