P2P Communication Frame Structure for Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadband wireless communication systems face inefficiencies in Peer-to-Peer (P2P) communications due to the separate allocation of radio resources, leading to reduced cellular system performance and increased communication fees.
Innovation Solution
Implementing a method for P2P communications that utilizes a frame structure overlapping with cellular communication frames and employs a contention-based channel, along with P2P dedicated channels, to minimize resource loss and enable efficient data exchange between terminals without base station intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate resource region is allocated for P2P communications, then P2P communication capability is improved, but cellular system performance deteriorates
Solution Approach 1:
The patent merges P2P communication resources with cellular communication resources by allowing terminals to perform P2P communications in the uplink region during timeslots when no cellular communication is occurring. This integration eliminates the need for separate P2P resource allocation, thereby maintaining cellular system performance while enabling P2P communication functionality.
Solution Approach 2:
The uplink region is designed to serve multiple functions: it can be used for both cellular uplink communications and P2P communications depending on the timeslot allocation. This multi-functionality allows the same radio resources to support both cellular and P2P services without requiring dedicated separate resources, thus resolving the contradiction between P2P capability and cellular performance.
2Adaptability or versatility
If a separate resource region is allocated for P2P communications, then P2P communication capability is improved, but communication costs increase
Solution Approach 1:
By merging P2P communications into the existing cellular uplink region rather than allocating separate resources, the system avoids the additional cost burden that would result from dedicated P2P resource allocation. Terminals share the uplink resources with cellular communications, eliminating the need for extra communication fees that would be required to offset the loss of capacity from separate P2P resource allocation.
3Ease of operation
If terminals use base station intervention for P2P communications, then connection establishment is simplified, but communication efficiency deteriorates
Solution Approach 1:
The patent enables terminals to establish P2P connections and exchange data directly without requiring continuous base station intervention. Terminals autonomously manage P2P connection establishment and data transmission in the uplink region during appropriate timeslots, thereby improving communication efficiency while maintaining ease of operation through automated connection management.
