Sounding Reference Signal Measurement for Multi-Point Mode Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently switching to a multi-point communication mode based on reference signal measurements, leading to potential link blockages and increased latency during scheduled communications.
Innovation Solution
A method and apparatus for wireless communication that involves receiving a sounding reference signal (SRS) prior to a scheduled communication, measuring its quality, and transmitting an indication if it does not satisfy a threshold, thereby activating a multi-point communication mode before the scheduled communication to ensure reliable data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system waits to detect link blockage before switching to multi-point communication mode, then the system complexity remains low, but the latency increases and communication reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by measuring reference signal quality (RSRP/RSRQ) before the scheduled communication occurs. When the reference signal measurement indicates poor link quality, the system proactively switches to multi-point communication mode in advance, avoiding the need to wait for actual communication failures. This preliminary detection and switching mechanism reduces latency while improving reliability.
2Reliability
If the system proactively switches to multi-point communication mode based on reference signal measurements, then communication reliability improves, but the device complexity increases
Solution Approach 1:
The system monitors changes in reference signal parameters (RSRP, RSRQ) and triggers mode switching based on predefined thresholds. By using parameter-based decision-making rather than complex algorithms, the system achieves reliable multi-point communication activation while keeping the control logic relatively simple. The parameter thresholds provide clear switching criteria that balance reliability improvement with manageable complexity.
3Productivity
If the system uses traditional post-failure switching to multi-point mode, then the processing overhead is low, but the productivity decreases due to retransmissions
Solution Approach 1:
The system performs preliminary quality assessment using reference signal measurements before the actual data transmission. By detecting poor link conditions in advance and switching to multi-point mode proactively, the system prevents communication failures and retransmissions. This eliminates the need for post-failure processing and maintains high productivity by ensuring successful first-attempt transmissions.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive, from a second device, a sounding reference signal (SRS) prior to a scheduled communication. The first device may transmit, to the second device, an indication that a measurement of the SRS does not satisfy a threshold, if the measurement of the SRS does not satisfy the threshold. The first device may activate, based at least in part on the transmitting the indication and before the scheduled communication, a multi-point communication mode. Numerous other aspects are described.
