Prioritizing Beam Failure Recovery Signals Over Scheduled Transmissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beam failure recovery procedures in wireless communication systems often face delays or failures due to signal overlap with scheduled transmissions, leading to undesirable outcomes.
Innovation Solution
A wireless device is configured to drop scheduled transmissions and transmit signals for beam failure recovery if the control channel overlaps with the scheduled transmission, allowing for successful and timely completion of the beam failure recovery procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless device transmits control signals for beam failure recovery, then the beam failure recovery procedure is completed successfully, but the scheduled transmission on another channel may overlap and cause transmission failure or delay
Solution Approach 1:
The wireless device performs preliminary detection to determine whether a control channel for beam failure recovery overlaps with a scheduled transmission on another channel before transmitting. This advance detection allows the device to proactively drop the scheduled transmission when overlap is detected, preventing transmission conflicts and ensuring timely beam failure recovery without causing delays from retransmissions or conflicts.
2Productivity
If the wireless device transmits control signals for beam failure recovery without dropping scheduled transmissions, then both transmissions can be maintained, but signal overlap leads to transmission failure
Solution Approach 1:
The wireless device acts as an intermediary that monitors and detects overlaps between control channels for beam failure recovery and scheduled transmissions on other channels. When an overlap is detected, the device selectively drops the scheduled transmission to prioritize the control signal, ensuring that critical beam failure recovery communications are not compromised by simultaneous transmissions that would cause interference and failure.

AI summary
Beam failure recovery (BFR) procedures are described for wireless communications. At least one transmission for BFR may overlap with a scheduled transmission. A wireless device may prioritize the at least one transmission for BFR, for example, over the scheduled transmission and may transmit the at least one transmission for BFR.
