Targeted MBS Paging Signaling via Segmented DCI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for paging in multicast and broadcast services (MBS) data transmission in wireless communication networks face inefficiencies in scheduling and data delivery, particularly in managing paging information across different radio resource control (RRC) states, leading to increased power consumption and unnecessary processing for non-interested UEs.
Innovation Solution
A method involving the reception of downlink control information (DCI) associated with a specific radio network temporary identifier (RNTI) for scheduling paging information, allowing UEs to selectively process and receive MBS data only when interested, thereby optimizing paging occasions and reducing unnecessary signaling and power usage.

Engineering Contradiction Analysis
1Reliability
If traditional paging methods are used for MBS data transmission, then all UEs receive paging information regardless of interest, but this causes increased power consumption and unnecessary processing for non-interested UEs
Solution Approach 1:
The paging information is segmented into two types: MBS-specific paging information (for MBS interest indication) and traditional paging information. UEs first receive and process the MBS-specific paging information to determine whether to activate MBS reception, thereby avoiding processing traditional paging information when not interested in MBS services.
Solution Approach 2:
The network performs preliminary action by sending MBS-specific paging information before traditional paging information. This preliminary notification allows UEs to determine in advance whether they need to process subsequent paging messages, enabling power-saving decisions before unnecessary processing occurs.
2Reliability
If traditional paging methods are used for MBS data transmission, then paging information is sent to all UEs, but this leads to increased system overhead and unnecessary signaling
Solution Approach 1:
The paging message structure is segmented with an MBS-specific indication field separated from traditional paging content. This segmentation allows the network to send targeted MBS paging information only to UEs that need it, reducing overall signaling overhead while maintaining reliable delivery for interested UEs.
3Productivity
If all UEs process paging information regardless of MBS interest, then paging delivery is simple, but this causes unnecessary processing for non-interested UEs
Solution Approach 1:
The paging processing logic is segmented into two stages: first, UEs process the MBS-specific indication field to determine MBS interest; second, based on this determination, UEs either proceed to process traditional paging information or enter power-saving mode. This segmentation improves overall processing efficiency by filtering out unnecessary processing while adding minimal complexity through a clear two-stage decision process.
Data Source
AI summary
A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives downlink control information (DCI) associated with a first radio network temporary identifier (RNTI) and used for scheduling paging information. The at least one of the first RNTI and the DCI indicates that the paging information, scheduled by the DCI, is associated with a first MBS service. The UE then receives MBS data based on the paging information.
