Hybrid CID Space for Wireless Peer-to-Peer Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies in spectrum utilization, particularly in peer-to-peer networks where identifying and communicating with disparate peers is challenging, leading to inefficient power use and interference management issues due to asynchronous operations and lack of effective identifier allocation.
Innovation Solution
The implementation of a hybrid transmission CID space that partitions resource units into orthogonal and non-orthogonal subsets, allowing devices to select and switch between them based on availability and robustness measures to maintain efficient peer-to-peer communication connections within shared frequency spectra.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peer-to-peer networks operate in an asynchronous manner allowing flexible peer discovery, then adaptability is improved, but interference management deteriorates due to lack of coordinated identifier allocation
Solution Approach 1:
The patent changes the parameter of identifier allocation from asynchronous/random to synchronous/coordinated. Connection identifiers are allocated in a synchronized manner within traffic management channel slots, transforming the operational mode from flexible but uncoordinated peer discovery to structured and coordinated identifier assignment, thereby reducing interference while maintaining adaptability
Solution Approach 2:
The patent introduces a traffic management channel slot as an intermediary structure that mediates identifier allocation between multiple peer-to-peer connections. This intermediary coordinates the assignment of connection identifiers, ensuring that identifiers are allocated in a structured manner that avoids interference while still allowing flexible peer discovery
2Device complexity
If connection identifiers are allocated without structured partitioning, then device complexity is reduced, but spectrum utilization deteriorates due to increased collisions and interference
Solution Approach 1:
The patent segments the connection identifier space into distinct subsets corresponding to different traffic management channel slots. Each subset is associated with specific orthogonal and non-orthogonal resource units, creating a structured partitioning that reduces collisions and improves spectrum utilization while maintaining manageable complexity through organized allocation
3Object-affected harmful factors
If orthogonal resource units are used for all connection identifiers, then interference is reduced, but spectrum utilization deteriorates due to inefficient use of non-orthogonal resources
Solution Approach 1:
The patent applies local quality by assigning different resource unit types to different connection identifier subsets based on local conditions. Orthogonal resource units are used for identifier subsets where interference avoidance is critical, while non-orthogonal resource units are used where spectrum efficiency is prioritized, optimizing both interference management and spectrum utilization

AI summary
An apparatus and method are disclosed for generating a transmission connection identifier (CID) for a transmitter/receiver pair in a wireless network. The CID may be selected from or mapped to a hybrid CID space comprising a first set of orthogonal CIDs and a second set of non-orthogonal (random or pseudo-random) CIDs. When a transmitter device wants to initiate a peer-to-peer connection with a receiver device, the transmitter and receiver devices attempt to obtain a CID to identify their connection within a traffic channel in a shared frequency space. The first and/or second device attempt to select a CID from the first set of orthogonal CIDs. However, if a CID collision is detected, the first and second devices select their CID from the second set of non-orthogonal CIDs. The selected transmission CID may be used during a time slot or interval to facilitate communications between the first and second devices.
