Wireless communication method, first device, and second device

A first device, comprising a processor, a memory and a transceiver,

• wherein the memory is configured to store a computer program, and the processor is configured to call the transceiver to run the computer program stored in the memory, to perform operations of:
• when a gap between two neighboring transmissions within Channel Occupancy Time (COT) is greater than or equal to a first gap, performing Category 2 Listen Before Talk (Cat 2 LBT) before a last transmission of the two neighboring transmissions is performed;
• wherein the first gap comprises a first maximum gap and/or a second maximum gap, the first maximum gap is a maximum gap, in which none of beams has data transmission, within the COT, and the second maximum gap is a maximum gap, in which one beam has no data transmission, within the COT;
• and
• resuming the last transmission based on a performing result of the Cat 2 LBT.

A second device, comprising a processor, a memory and a transceiver,

• wherein the memory is configured to store a computer program, and the processor is configured to call the transceiver to run the computer program stored in the memory, to perform operations of:
• when a gap, which is between a transmission of a first device within Channel Occupancy Time (COT) and a transmission of the second device when the COT is shared, is greater than or equal to a second maximum gap, performing Category 2 Listen Before Talk (Cat 2 LBT) before the transmission of the second device is performed;
• wherein the transmission of the first device is a transmission on a beam, which corresponds to the second device, within the COT, and the second maximum gap is a maximum gap, in which one beam has no data transmission, within the COT;
• and
• performing the transmission of the second device based on a performing result of the Cat 2 LBT.
