Problem

Existing wireless communications systems face challenges in effectively sending and receiving remote interference management reference signals (RIM-RS) due to uncertainties in interference distance and delay caused by atmospheric ducting, leading to cross-link interference between network devices.

Innovation Solution

A method for determining transmission resources of RIM-RS based on identification and parameter information, including sequence, frequency, and time domain resources, allowing flexible configuration to meet varying network configurations and detection requirements, reducing detection complexity and improving interference coordination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional communication protocols are used for device-to-device communication, then compatibility and ease of operation are improved, but communication latency increases and productivity deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidproductivity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The communication system is segmented into two distinct protocols: a first protocol for device-to-device communication that prioritizes low latency and high productivity, and a second protocol for device-to-network communication that ensures compatibility. This segmentation allows each protocol to be optimized for its specific purpose without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically selects between different communication protocols based on the communication scenario. The processing circuitry determines whether to use the first protocol (for direct device communication) or the second protocol (for network-mediated communication), enabling adaptive optimization of communication performance.
