Multi-Tier Resource Allocation for MBMS Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in efficiently supporting broadcast and multicast services, as existing methods do not effectively manage resources for multimedia broadcast/multicast services (MBMS), leading to suboptimal service delivery and user experience.
Innovation Solution
Implementing a multi-tier resource structure for MBMS services, where resources for the multicast control channel (MCCH) are signaled in a system information block (SIB), and subsequent resources for data channels are signaled via the MCCH, allowing base stations to determine and transmit these resources, and user equipment to receive and decode them efficiently.

Engineering Contradiction Analysis
1Productivity
If resources for MCCH are signaled in SIB and resources for data channels are signaled via MCCH (multi-tier structure), then resource allocation efficiency and service delivery are improved, but system complexity and signaling overhead increase
Solution Approach 1:
The patent divides resource signaling into two distinct tiers: first-tier resources (MCCH) are signaled in SIB, while second-tier resources (data channels) are signaled via MCCH. This segmentation allows efficient hierarchical management where general resource allocation is established first, then specific data channel resources are assigned, improving overall resource allocation efficiency while maintaining manageable system complexity through structured organization.
2Reliability
If a multi-tier resource structure is implemented for MBMS services, then service delivery and user experience are improved, but the complexity of resource management increases
Solution Approach 1:
The patent implements preliminary action by first signaling first-tier resources (MCCH) in the SIB before signaling second-tier resources (data channels) via the MCCH. This preliminary establishment of control channel resources ensures that the foundation for reliable service delivery is laid first, allowing subsequent data channel allocations to build upon this established framework, thereby improving service delivery while managing complexity through sequential resource establishment.

AI summary
Techniques for supporting multimedia broadcast/multicast services (MBMS) are described. In an aspect, resources used for MBMS services may be provided with a multi-tier structure. In the first tier, resources (e.g., subframes) used for a multicast control channel (MCCH) for MBMS services may be signaled in a system information block (SIB). In the second tier, resources (e.g., subframes) for channels carrying data for MBMS services may be signaled via the MCCH. In one design, a base station/cell may determine resources used to send a MCCH. The cell may generate a SIB comprising information indicative of the resources used to send the MCCH. The cell may send the SIB in a broadcast control channel (BCCH). The cell may send the MCCH on the resources indicated by the information sent in the SIB. The cell may send other channels carrying data for MBMS services based on information sent in the MCCH.
