D2D Communication Anchor Sub Resource Pool for Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device-to-device (D2D) communication technologies face challenges in achieving low power consumption while enhancing communication quality, particularly in wearable terminals and IoT devices, which require reliable and efficient communication with varying traffic volumes and mobility.
Innovation Solution
A communication apparatus and terminal apparatus that utilize a resource pool with multiple sub resource pools, where one sub resource pool acts as an anchor for control information, allowing efficient monitoring and resource allocation to reduce power consumption and improve communication quality by optimizing resource usage and handover processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device monitors all resource pools for control information, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The resource pool is segmented into multiple sub resource pools, with one designated as an anchor sub resource pool that contains control information. The device only needs to monitor the anchor sub resource pool for control information rather than all sub resource pools, reducing monitoring complexity and power consumption while maintaining reliable communication through centralized control information management.
2Adaptability or versatility
If multiple sub resource pools are used for different traffic types, then communication quality for various services is improved, but device complexity increases
Solution Approach 1:
The resource pool is divided into multiple sub resource pools, each potentially optimized for different traffic types or service requirements. This segmentation allows the system to support diverse communication services (e.g., voice, data, critical communications) with appropriate resource allocation while maintaining manageable complexity through the anchor sub resource pool structure that centralizes control information.
Solution Approach 2:
The anchor sub resource pool serves as a universal control structure that manages resources across all sub resource pools. This multi-functional anchor pool handles control information for diverse traffic types without requiring separate control mechanisms for each sub resource pool, reducing overall system complexity while maintaining adaptability.

AI summary
There is provided a communication apparatus including a setting unit that sets a resource for device-to-device communication, in which the setting unit sets a resource pool including a plurality of sub resource pools as a resource for the device-to-device communication. One of the sub resource pools is an anchor sub resource pool that stores control information for monitoring by the device that performs the device-to-device communication.
