Resource Indication for Interference Measurement in Full-Duplex
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In full-duplex communication mode, network-side devices face challenges in performing interference measurements on downlink resources due to limited self-interference suppression capabilities, leading to resource wastage and demodulation errors in terminals.
Innovation Solution
A resource indication method where a network-side device determines resources for interference measurement and sends first indication information to a terminal, allowing the terminal to configure resources accordingly, thereby avoiding interference and resource wastage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network-side device performs interference measurement on downlink resources in full-duplex mode, then interference measurement capability is improved, but resource wastage and demodulation errors occur due to limited self-interference suppression capabilities
Solution Approach 1:
The patent extracts the interference measurement function from the normal data transmission resources by designating specific resources exclusively for interference measurement. This separation allows the network-side device to perform accurate interference measurement without the terminal expecting data or reference signals on those resources, thereby eliminating resource wastage and demodulation errors while maintaining full-duplex operation
Solution Approach 2:
The network-side device performs interference measurement on predetermined resources before normal data transmission occurs. By conducting interference measurement in advance on dedicated resources, the system obtains accurate interference information without affecting subsequent data transmission reliability, resolving the contradiction between measurement accuracy and transmission reliability
2Productivity
If full-duplex mode is implemented on the network side, then throughput is increased, but more communication resources are interfered with due to limited self-interference suppression
Solution Approach 1:
The patent segments communication resources into distinct categories: some resources are allocated for uplink transmission, others for downlink transmission, and specific resources are designated exclusively for interference measurement. This segmentation allows the network-side device to operate in full-duplex mode for increased throughput while simultaneously monitoring and managing interference on dedicated measurement resources, thereby reducing overall interference impact on communication resources
3Reliability
If the terminal expects data or reference signals on all downlink resources, then communication reliability is maintained, but resource wastage occurs when interference measurement is performed
Solution Approach 1:
The network-side device informs the terminal in advance about specific resources designated for interference measurement. The terminal then adjusts its reception behavior accordingly by not expecting data or reference signals on those predetermined resources. This preliminary notification mechanism maintains communication reliability on actual data resources while eliminating resource wastage on interference measurement resources
