Sidelink DRX Parameter Switching for V2X Power and Reception Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Vehicle-to-Everything (V2X) or New Radio (NR) V2X systems, the continuous power consumption of vehicle-mounted terminals due to continuous transmitting and receiving design hinders power saving, despite having continuous power supply, and existing solutions fail to address this issue effectively.
Innovation Solution
A method for processing discontinuous reception parameters is implemented, where different DRX parameters or parameter values are set based on various communication parameters such as transmission modes, service types, RAT types, interface types, and carrier frequencies to enable power-saving data transmission and reception on a sidelink.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If discontinuous reception is used to save battery power, then power consumption is reduced, but reception quality deteriorates due to packet loss
Solution Approach 1:
The system implements feedback mechanisms where the terminal notifies the network side of reception status, and the network side adjusts transmission parameters based on this feedback to maintain reception quality while enabling discontinuous reception for power saving
Solution Approach 2:
The system dynamically changes reception parameters such as reception window size, retransmission thresholds, and scheduling intervals based on channel conditions and power saving requirements to balance between power consumption and reception quality
2Reliability
If reception parameters are frequently adjusted to adapt to channel changes, then reception quality improves, but processing complexity increases
Solution Approach 1:
The system implements dynamic parameter adjustment where reception parameters are automatically adapted based on real-time channel conditions using algorithms that balance between responsiveness to channel changes and processing complexity
Solution Approach 2:
The system performs preliminary parameter configuration and pre-establishes parameter adjustment rules before actual reception occurs, reducing the complexity of real-time processing while maintaining adaptability to channel changes
3Use of energy by moving object
If discontinuous reception is implemented, then battery power is saved, but packet loss increases
Solution Approach 1:
The system implements error correction codes, redundancy packets, and buffering mechanisms before discontinuous reception causes packet loss, providing a cushion that compensates for potential information loss while maintaining power saving benefits
Solution Approach 2:
The system uses feedback mechanisms where the terminal notifies the network side of reception status, enabling the network to retransmit lost packets or adjust transmission to prevent packet loss while maintaining discontinuous reception for power saving

AI summary
The present application discloses a method for processing discontinuous reception parameters, a storage medium and a processor. The method comprises: user equipment receiving discontinuous reception parameters and parameter values, the discontinuous reception parameters corresponding to different communication parameters being different, or the parameter values of the discontinuous reception parameters corresponding to different communication parameters being different; and the user equipment performing configuration on the basis of the discontinuous reception parameters and the parameter values. The present application solves the technical problems in the related art of being unable to achieve the purpose of power saving as user equipment has a large power consumption when transmitting data (such as a direct communication request (DCR) message or a discovery message) on a sidelink.
