Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in configuring effective connection establishment timers for sidelink communication, particularly in scenarios involving UE-to-Network sidelink relays, which affect communication reliability and efficiency.
Innovation Solution
The proposed solution involves determining a set of sidelink connection timers for communication establishment with a network node using a UE-to-Network sidelink relay, where the respective values for each timer are based on initial sets received from system information blocks, and these timers are used to supervise communication establishment procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection establishment timers are configured for sidelink communication via UE-to-Network relays, then communication reliability is improved, but device complexity increases due to additional timer configuration and management requirements
Solution Approach 1:
The patent introduces an intermediary mechanism where the relay UE acts as a mediator between the remote UE and the network. The relay UE receives timer configurations from the network and forwards them to the remote UE, simplifying the overall system architecture while ensuring reliable timer management for sidelink communication establishment.
Solution Approach 2:
The patent segments the timer configuration process into distinct components: network-configured timers for general sidelink communication and relay-specific timers for relay-assisted communication. This segmentation allows independent optimization of each timer set and reduces the complexity of managing all timers uniformly across different communication scenarios.
2Adaptability or versatility
If multiple sets of connection timers are configured for different sidelink scenarios, then adaptability is improved, but device complexity increases due to multiple timer sets to manage
Solution Approach 1:
The patent implements dynamic timer selection where the UE can adaptively choose between directly configured timers and relay-determined timers based on the current communication scenario. This dynamic approach provides versatility for different sidelink scenarios while reducing the need to permanently maintain multiple complete timer sets, thereby managing complexity.
Solution Approach 2:
The patent creates a universal timer configuration framework where a single timer configuration mechanism can serve multiple purposes: direct sidelink communication, relay-assisted communication, and different QoS requirements. The relay UE determines appropriate timer values based on the specific scenario, making the system multi-functional without requiring separate dedicated timer sets for each function.

AI summary
Apparatuses, methods, and systems are disclosed for configuring sidelink (“SL”) connection timers. One method includes receiving a set of connection timers from a first system information block (“SIB”) transmission of a serving node and receiving first set of SL connection timers from an additional SIB of the serving node. The method includes determining a second set of SL connection timers for communication establishment with a network node-base station using a UE-to-Network (“U2N”) SL relay UE, where a respective value for each timer in the second set of SL connection timers is determined based at least in part on the first set of SL connection timers. The method includes using a respective connection timer to supervise communication establishment with the base station via the U2N SL relay UE.
