TRS burst transmission method and apparatus

A tracking reference signal (TRS) burst transmission method, comprising:

• determining, by a transmit end, to send a second TRS burst in a first slot that is in a first maximum channel occupancy time (MCOT) and whose distance to a start slot of a previous tracking reference signal (TRS) burst is greater than or equal to Y slots, wherein Y is an integer greater than or equal to 2;
• if a length of the first MCOT is greater than the Y slots, a first TRS burst is sent in another slot in the first MCOT at distance greater than or equal to the Y slots;
• if a distance between an end slot in a previous MCOT and a start slot of the previous TRS burst is less than or equal to the Y slots, determining not to send the first TRS burst in the previous MCOT;
• and
• sending, by the transmit end, indication information to a receive end, wherein the indication information is used to indicate the first slot for sending the second TRS burst.

A tracking reference signal (TRS) burst transmission apparatus, comprising:

• a memory configured to store an instruction;
• a transceiver configured to communicate with another device and a processor configured to execute the instruction stored in the memory, so as to:
• determine to send a first TRS burst in a first slot of a first maximum channel occupancy time (MCOT);
• if a length of the first MCOT is greater than Y slots, determine to send a second TRS burst in a slot that is in the first MCOT and whose distance to a start slot of the first TRS burst is Y slots, wherein Y is an integer greater than or equal to 2;
• if a distance between an end slot in the first MCOT and a start slot of a last TRS burst of a previous MCOT is less than or equal to the Y slots, the first TRS burst is not sent, and determine to send the second TRS burst in the slot that is in next MCOT and whose distance to the start slot of the last TRS burst of the previous MCOT is greater than the Y slots;
• and
• sending indication information to a receive end, wherein the indication information is used to indicate the first slot for sending the second TRS burst.

• a memory configured to store an instruction;
• a transceiver configured to communicate with another device;
• and
• a processor configured to execute the instruction stored in the memory, so as to:
• determine a first maximum channel occupancy time (MCOT) in a first time period, and send a first TRS burst in a first slot in the first time period, wherein the first time period comprises Y slots, Y is an integer greater than or equal to 2, and the first time period is any one of a plurality of consecutive time periods into which a time axis is divided;
• if a distance between an end slot in the first MCOT and a start slot of a last TRS burst of a previous MCOT is less than or equal to the Y slots, the first TRS burst is not sent, and determine to send a second TRS burst in a slot that is in next MCOT and whose distance to the start slot of the last TRS burst of the previous MCOT is greater than the Y slots;
• and
• sending indication information to a receive end, wherein the indication information is used to indicate the first slot for sending the first TRS burst.
