Solution Overview

Problem

Current communication systems in WWAN face inefficiencies in concurrent WWAN and peer-to-peer communication, as existing methods do not effectively utilize available resources, particularly in terms of bandwidth allocation and signal quality for peer-to-peer data transmission.

Innovation Solution

The method involves partitioning peer-to-peer data resources into two sets with different bandwidths, where one set is parallel in time with non-peer-to-peer resources, and determining data transmission based on estimated signal quality to optimize resource utilization by allocating links with lower signal quality to higher bandwidth resources and those with higher signal quality to lower bandwidth resources.

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If peer-to-peer communication uses dedicated time/frequency resources separate from WWAN resources, then interference between WWAN and peer-to-peer communication is reduced, but resource utilization efficiency deteriorates

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent merges WWAN resources and peer-to-peer resources into a unified resource pool, allowing dynamic sharing between the two communication types. The base station coordinates resource allocation to enable both WWAN communications and peer-to-peer communications to use the same time/frequency resources, thereby improving overall resource utilization while maintaining acceptable interference levels through scheduling and power control mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If peer-to-peer data transmission uses fixed bandwidth resources, then resource allocation is simple, but adaptability to different signal quality conditions deteriorates

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic resource allocation where the bandwidth and resource selection for peer-to-peer transmission adapt based on real-time signal quality conditions. The system determines channel quality indicators and adjusts the allocation of peer-to-peer resources accordingly, allowing links with lower signal quality to access higher bandwidth resources while maintaining manageable complexity through automated base station coordination and pre-defined resource pools.

Inventive Principle:

3Productivity

If peer-to-peer communication shares resources with WWAN communication, then resource utilization efficiency improves, but interference between communication types increases

Engineering Contradiction:

Solution Approach 1:

The patent employs feedback mechanisms where the base station monitors interference levels and channel conditions between WWAN and peer-to-peer communications. Based on this feedback, the base station dynamically adjusts resource allocation, power levels, and scheduling decisions to optimize the balance between resource utilization and interference management, allowing efficient shared resource usage while maintaining communication quality.

AI summary

A method of operating a wireless device includes communicating in one of peer-to-peer data resources or non peer-to-peer resources. The peer-to-peer data resources include a first set of peer-to-peer resources with a first bandwidth and a second set of peer-to-peer resources with a second bandwidth greater than the first bandwidth. The first set of peer-to-peer resources is parallel in time with the non peer-to-peer resources. In addition, the method includes estimating a signal quality for a data transmission on the peer-to-peer data resources. Furthermore, the method includes determining whether to send the data transmission in one of the first set of peer-to-peer resources or the second set of peer-to-peer resources based on the estimated signal quality.
