Traffic priority-based energy detection threshold adaption in unlicensed band

A second device comprising:

• at least one processor;
• and
• at least one memory including computer program codes,
• the at least one memory and the computer program codes are configured to, with the at least one processor, cause the second device at least to:
• in response to receiving, from a first device, uplink data transmitted based on a target configuration parameter, determine a target traffic priority for transmitting the uplink data, the target configuration parameter being associated with at least one candidate configuration parameter of an energy detection threshold for channel clearance assessment for the target traffic priority;
• and
• determine an allowable output power level for transmitting the uplink data at least based on the target traffic priority, wherein the allowable output power level is determined according to a regulator-driven computation that constrains maximum output power as a function of a maximum energy detection threshold,
• wherein the second device is further caused to:
• determine an expected candidate configuration parameter from the at least one candidate configuration parameter based on at least the following:
• a channel access probability for the target traffic priority being lower than a threshold probability,
• an interference level at the first device exceeding a first threshold level,
• an interference level at the second device exceeding a second threshold level,
• a co-channel interference from a further data transmission having a further target traffic priority being detected, and
• a channel occupancy time sharing between the first device and the second device being to be stopped;
• and
• transmit an indication of the expected candidate configuration parameter to the first device.

• receiving an indication of at least the following:
• a set of candidate offsets related to a reference energy detection threshold for the channel clearance assessment for the target traffic priority,
• a set of candidate energy detection thresholds for the channel clearance assessment for the target traffic priority, and
• a set of candidate offsets related to a reference power threshold of an output power level of the first device;
• and
• determining the at least one candidate configuration parameter based on the indication,
