Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiple-access wireless communication systems face challenges in efficiently discovering and configuring peer-to-peer (P2P) links between user equipment devices without apparent optimal solutions, affecting communication efficiency and quality.
Innovation Solution
The method involves the base station providing P2P configuration information, including physical layer and medium access control resources, UE identities, and service credentials, to enable P2P communication directly between user equipment devices, allowing them to discover and establish P2P links autonomously or with base station assistance.

Engineering Contradiction Analysis
1Productivity
If user equipment devices perform autonomous peer discovery and P2P link establishment, then communication efficiency is improved, but system complexity and interference management become more difficult
Solution Approach 1:
The base station serves as an intermediary that provides P2P configuration information to user equipment, including resource allocation, synchronization parameters, and interference coordination data. This mediator approach enables autonomous P2P communication while maintaining network control and simplifying the complexity burden from devices.
2Reliability
If P2P configuration information includes detailed resource allocation, then communication quality is improved, but signaling overhead increases
Solution Approach 1:
The base station provides P2P configuration information in advance, including pre-allocated resource blocks, synchronization parameters, and interference coordination data. This preliminary action enables UEs to establish P2P links quickly without extensive real-time signaling, reducing overhead while maintaining communication quality.
3Reliability
If base station provides comprehensive P2P configuration information, then P2P link robustness is improved, but network control and coordination complexity increase
Solution Approach 1:
The P2P configuration information is segmented into distinct components including resource allocation, synchronization parameters, interference coordination data, and authentication credentials. This segmentation allows the base station to provide comprehensive configuration for robust P2P links while managing complexity through modular, organized information delivery.

AI summary
Configuring a peer-to-peer (P2P) link in a multi-access wireless network includes receiving P2P configuration information from a base station at a UE supporting P2P communication. The first UE communicates directly with a second UE based on the P2P configuration information received from the base station. The first UE may send a configuration request message to the base station, and receive a responsive configuration message with the P2P configuration information from the base station, which messages may be Radio Resource Control (RRC) messages supporting P2P. In the alternative, the P2P configuration information may be provided in a system information block (SIB) broadcast by the base station. The P2P configuration information may indicate allocation of physical layer or Medium Access Control resources, or both allocated for P2P communication, and other information.
