Base Station Coordinated Sidelink Allocation for Pedestrian-to-Vehicle Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G communication systems face challenges in effectively providing pedestrian-to-vehicle (P2V) data transmission and reception, particularly in dangerous areas, with existing methods lacking efficient resource allocation and power management for pedestrian user equipment (P-UE) in vehicle-to-everything (V2X) communication scenarios.
Innovation Solution
The proposed method involves a base station identifying when a vehicle user equipment (UE) enters a dangerous area and transmitting a message to a pedestrian UE, allowing the P-UE to request and allocate sidelink resources for P2V data transmission, thereby reducing power consumption through assisted transmission and reception with a vehicle UE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pedestrian UE autonomously monitors and transmits P2V data continuously, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The base station acts as an intermediary that receives location information from both the vehicle UE and pedestrian UE, determines dangerous areas, and triggers P2V data transmission only when necessary. This mediator approach eliminates the need for continuous autonomous monitoring by the pedestrian UE, significantly reducing power consumption while maintaining communication reliability through base station-coordinated transmission.
2Productivity
If sidelink resources are allocated for P2V communication, then communication efficiency is improved, but resource allocation complexity increases
Solution Approach 1:
The base station pre-allocates sidelink resources for P2V communication before actual transmission occurs. By determining dangerous areas in advance and preparing resource allocations beforehand, the system achieves efficient P2V communication without complex real-time resource allocation decisions, simplifying the overall resource management process.

AI summary
Provided are a method and apparatus for transmitting or receiving data in a wireless communication system. An operating method of a base station for transmitting and receiving pedestrian-to-vehicle (P2V) data includes: identifying whether a vehicle user equipment (UE) enters a preset dangerous area; when it is identified that the vehicle UE enters the dangerous area, transmitting a message related to the dangerous area to a pedestrian UE (P-UE); receiving, from the P-UE, a request for allocation of sidelink resources for transmitting and receiving P2V data to and from the vehicle UE; and allocating the sidelink resources to the P-UE.
