P2P Resource Coordination via Distributed Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in efficiently supporting peer-to-peer (P2P) communication due to interference from wide area network (WAN) devices, and there is a need for effective resource management to optimize P2P communication performance.
Innovation Solution
The implementation of resource partitioning and distributed negotiation techniques, where a network entity allocates resources with minimal interference from WAN communication, allowing P2P groups to autonomously negotiate and assign resources for P2P communication, and a network entity can participate in resource negotiation to assist and reclaim resources as needed.

Engineering Contradiction Analysis
1Productivity
If resource partitioning is implemented to allocate resources for P2P communication, then P2P communication efficiency is improved, but device complexity increases
Solution Approach 1:
The patent divides available communication resources into separate partitions: some resources are allocated for WAN communication while other resources are designated for P2P communication. This segmentation allows P2P groups to use dedicated resources without interfering with WAN operations, thereby improving P2P communication efficiency while the network entity manages the partitioning to avoid excessive device complexity
Solution Approach 2:
The network entity acts as an intermediary that performs resource partitioning and manages resource allocation. By centralizing the complexity of resource management at the network entity level rather than at individual devices, the system achieves efficient P2P communication while preventing device complexity from becoming unmanageable
2Adaptability or versatility
If P2P groups perform autonomous resource negotiation, then network transparency is improved, but reliability decreases
Solution Approach 1:
P2P groups autonomously negotiate and allocate resources among themselves without requiring continuous network entity intervention. This self-service mechanism improves network transparency by allowing P2P communication to operate independently. The network entity provides initial resource partitioning and can intervene when necessary, maintaining reliability while preserving the autonomous nature of P2P resource management
Solution Approach 2:
The system incorporates feedback mechanisms where P2P groups report resource usage and negotiation outcomes to the network entity, which monitors and can intervene to maintain reliability. This feedback loop ensures that autonomous negotiation does not compromise overall system reliability while preserving network transparency
3Ease of operation
If distributed negotiation is used for resource allocation, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The network entity performs preliminary resource partitioning before P2P groups engage in distributed negotiation. This preliminary action establishes a structured framework that guides subsequent negotiations, reducing the complexity and potential for information loss during distributed exchanges. Devices negotiate within predefined resource boundaries, making the process easier to operate while minimizing information loss

AI summary
Techniques for determining resources to use for peer-to-peer (P2P) communication are disclosed. In an aspect, a network entity may receive feedback information (e.g., resource usage information and/or channel state information) from P2P devices and may perform resource partitioning based on the feedback information to allocate some of the available resources for P2P communication. The allocated resources may observe little or no interference from devices engaged in wide area network (WAN) communication. In another aspect, P2P groups may perform resource negotiation via a WAN connection (e.g., with little or no involvement by the WAN) to assign the allocated resources to different P2P groups. In yet another aspect, a device may autonomously determine whether to communicate with another device directly or via a WAN, e.g., whether to initiate P2P communication with another device and whether to terminate P2P communication. In yet another aspect, a network entity may participate in resource negotiation by P2P devices.
