Peer Discovery Resource Block Hopping in LTE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE technology, face challenges in efficiently managing resource block pairs for peer discovery messages, leading to potential overlap and interference, which affects the ability of user equipment (UE) to effectively discover peers and optimize resource allocation.
Innovation Solution
The method involves determining a second set of resource block pairs for transmitting peer discovery messages based on a one-to-one mapping of the first set in a first time cycle to the second set in a second time cycle, allowing for efficient hopping of allocated resources to avoid overlap and improve peer discovery efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource block pairs are allocated for peer discovery messages in wireless communication systems, then peer discovery capability is enabled, but resource overlap and interference occur leading to reduced detection efficiency
Solution Approach 1:
The patent implements dynamic resource block pair allocation where the network device dynamically determines and assigns different resource block pairs to different user equipment for peer discovery message transmission. This dynamic allocation prevents fixed resource conflicts and reduces interference by adapting resource assignments to current system conditions and user requirements.
Solution Approach 2:
The patent applies local quality by allowing different user equipment to use different resource block pairs for peer discovery messages based on their specific needs and locations. Each UE can be assigned appropriate resources tailored to its situation, rather than using a uniform allocation scheme, thereby reducing overlap and improving detection efficiency in local areas.
2Productivity
If resource block pairs are allocated for peer discovery messages, then peer discovery function is provided, but resource allocation efficiency is reduced due to overlap
Solution Approach 1:
The patent implements feedback mechanisms where user equipment reports resource usage and detection status to the network device. Based on this feedback, the network device can optimize resource block pair allocations, identify and resolve overlaps, and improve overall resource allocation efficiency while reducing redundant resource assignments.
Solution Approach 2:
The patent enables user equipment to autonomously select and use assigned resource block pairs for peer discovery message transmission without requiring continuous network intervention. This self-service approach improves resource allocation efficiency by reducing signaling overhead and allowing UEs to independently manage their discovery resources.

AI summary
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines a second set of resource block pairs on which to transmit a peer discovery message in a second time cycle based on a mapping of a first set of resource block pairs in a first time cycle to the second set of resource block pairs in the second time cycle. The mapping is a one-to-one mapping between each resource block pair in the first set of resource block pairs to a corresponding resource block pair in the second set of resource block pairs. Resource block pairs in the first set of resource block pairs may be in adjacent allocated resources. The UE transmits the peer discovery message in the determined second set of resource block pairs.
