Idle Multicast Reception Negotiation With Reduced UE Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G multicast services face challenges in maintaining service quality due to inactive/idle reception by UEs, which leads to increased transmission errors without feedback, affecting radio transmission adjustments.
Innovation Solution
Implementing a mechanism to enable and control the transmission mode for inactive/idle reception of multicast services, allowing UEs to receive multicast sessions with reduced feedback, thereby improving service quality and reducing transmission errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If inactive/idle reception mode is used for multicast, then the number of UEs that can receive multicast increases, but transmission errors increase due to lack of feedback
Solution Approach 1:
The patent changes the operational parameters of UE by introducing inactive/idle reception mode with modified feedback behavior. UEs in this mode receive multicast transmissions but suppress or reduce feedback messages, effectively changing the interaction parameters between UE and network to accommodate higher UE density while managing transmission reliability through alternative means.
2Reliability
If feedback is sent from UE to network for multicast reception, then transmission quality is maintained, but network overhead increases
Solution Approach 1:
The patent extracts the feedback mechanism from the standard multicast reception process by introducing an inactive/idle reception mode where feedback is removed or significantly reduced. This separation allows the system to maintain reliable transmission quality for UEs that need it while allowing other UEs to receive multicast content with minimal network overhead by simply monitoring transmissions without sending feedback.

AI summary
An apparatus, in a user equipment, is provided, the apparatus comprising: at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to receive an indication whether a transmission mode for inactive/idle reception of multicast is applied for a multicast session, and based on the indication, perform procedures to enable reception of the multicast session using the transmission mode for inactive/idle mode reception.
