UPLINK LISTEN BEFORE TALK FAILURE HANDLING

Abstract:

Apparatuses, systems, and methods for a handling uplink listen before talk (LBT) procedure failures in unlicensed bands of 5G NR. A wireless device may count a number of failed transmissions due to LBT procedure failures, e.g., that may occur in one or more transmit/receive occasions. The wireless device may determine that the count has met a threshold, e.g., that a number of failed transmissions has reached the threshold. The wireless device may initiate a recovery procedure based on determining that the count has met the threshold.
