Solution Overview
Problem
Existing 5G wireless communication systems face challenges in efficiently managing varying resource demands from mobile devices, particularly in handling emergency paging messages while minimizing latency and maintaining reliability, especially in contexts like URLLC and eMBB.
Innovation Solution
Implementing a method where a radio network node transmits emergency paging occasion configurations to user equipment, enabling the use of discontinuous transmit off periods with specific emergency paging resources, allowing for efficient transmission of emergency messages during these periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If discontinuous transmit off periods are activated to reduce energy consumption, then energy efficiency is improved, but emergency message delivery reliability deteriorates
Solution Approach 1:
The patent segments paging resources into emergency paging occasions and non-emergency paging occasions. During discontinuous transmit off periods, the network node selectively transmits only emergency paging messages on emergency paging occasions, while non-emergency paging transmissions are suspended. This segmentation allows the system to maintain energy efficiency through discontinuous transmission while ensuring emergency messages are reliably delivered during available transmission windows.
2Loss of time
If emergency paging messages are transmitted during discontinuous transmit off periods, then latency is reduced, but resource usage efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the network node adapts paging transmission behavior based on the operational state (discontinuous transmit off periods). During these periods, the system dynamically switches to using emergency paging occasions for critical messages, accepting reduced overall resource efficiency in exchange for minimized emergency message latency. This dynamic adaptation allows the system to prioritize time-critical communications when needed.
3Reliability
If emergency paging occasion configurations are implemented, then emergency message delivery reliability is improved, but system complexity increases
Solution Approach 1:
The patent employs preliminary configuration where emergency paging occasion parameters are pre-established and communicated to user equipment before discontinuous transmit off periods begin. This advance setup includes configuring emergency paging resource indicators, time/frequency resources, and monitoring parameters. By performing this configuration work beforehand, the system achieves reliable emergency message delivery during operational periods without requiring complex real-time decision-making or configuration changes, thus limiting the increase in system complexity.

AI summary
A radio network node may receive, from a core network, an on-demand paging configuration comprising an indication to enable synchronization signal block transmission during discontinuous transmit off operation. The node may configure user equipment to be associated with a paging occasion group corresponding to one or more paging occasion resources. The node may broadcast a paging message indication via a synchronization signal block during a discontinuous transmit off period. The node may broadcast, using a broadcast scrambling code, a paging message indication via a configured emergency paging occasion if synchronization signal block transmission during discontinuous transmit off has not been enabled. A paging message indication may comprise a paging occasion group indication. User equipment corresponding to a paging occasion group indicated in a paging message indication may receive a paging message transmitted by the node, during configured discontinuous transmit off operation, via a paging occasion corresponding to the group.
