Communication method, apparatus, device, and system, and storage medium for avoiding uplink transmission interference
This application provides a communication method, and apparatus. The communication method includes: a terminal device receives indication information from a network device, wherein the indication information indicates a first time-frequency resource, the terminal device adjusts sending of a sounding reference signal (SRS) in a second time-frequency resource based on the indication information.
1. A communication method, applied to a communication apparatus, comprising:
receiving indication information from a network device, wherein the indication information indicates a first time-frequency resource; and
in a case of the first time-frequency resource overlapping K1 symbols in K consecutive symbols in a time domain and not overlapping with K2 symbols other than the K1 symbols in the K consecutive symbols in the time domain, wherein the K consecutive symbols are configured for transmitting a sounding reference signal (SRS),
a sum of K1 and K2 is equal to K, and in a case of a third time interval being less than a fourth time interval:
transmitting the SRS to the network device on the K2 symbols; and
canceling SRS transmission on the K1 symbols,
wherein:
the third time interval is a time amount required by a terminal device to process the indication information, and
the fourth time interval is between a first time at which the terminal device receives the indication information and a second time at which the terminal device starts to send the SRS.
2. The method according to claim 1 , wherein the SRS is repeatedly sent on symbols in one slot.
3. The method according to claim 1 , wherein:
all of the K1 symbols are located in the first time-frequency resource.
4. The method according to claim 1 , wherein the indication information is group-common signaling.
5. The method according to claim 1 , wherein the indication information is an uplink cancelation indication.
6. The method according to claim 1 , wherein:
at least one symbol of the K1 symbols is located in the first time-frequency resource, and other symbols of the K1 symbols are located outside the first time-frequency resource.
7. A communication apparatus, comprising at least one processor coupled to at least one memory, and the at least one processor is configured to execute program instructions stored in the at least one memory, to cause the communication apparatus to perform the following:
receiving indication information from a network device, wherein the indication information indicates a first time-frequency resource; and
in a case of the first time-frequency resource overlapping K1 symbols in K consecutive symbols in a time domain and not overlapping with K2 symbols other than the K1 symbols in the K consecutive symbols in the time domain, wherein the K consecutive symbols are configured for transmitting a sounding reference signal (SRS),
a sum of K1 and K2 is equal to K, and in a case of a third time interval being less than a fourth time interval:
transmitting the SRS to the network device on the K2 symbols; and
canceling SRS transmission on the K1 symbols,
wherein:
the third time interval is a time amount required by the apparatus to process the indication information, and
the fourth time interval is between a first time at which the apparatus receives the indication information and a second time at which the apparatus starts to send the SRS.
8. The apparatus according to claim 7 , wherein the SRS is repeatedly sent on symbols in one slot.
9. The apparatus according to claim 7 , wherein:
all of the K1 symbols are located in the first time-frequency resource.
10. The apparatus according to claim 7 , wherein the indication information is group-common signaling.
11. The apparatus according to claim 7 , wherein the indication information is an uplink cancelation indication.
12. The apparatus according to claim 7 , wherein:
at least one symbol of the K1 symbols is located in the first time-frequency resource, and other symbols of the K1 symbols are located outside the first time-frequency resource.
13. A communication apparatus, comprising at least one processor coupled to at least one memory, and the at least one processor is configured to execute program instructions stored in the at least one memory, to cause the apparatus to perform the following:
sending indication information to a terminal device, wherein the indication information indicates a first time-frequency resource; and
in a case of the first time-frequency resource overlapping K1 symbols in K consecutive symbols in a time domain and not overlapping with K2 symbols other than the K1 symbols in the K consecutive symbols in the time domain, wherein the K consecutive symbols are configured for transmitting a sounding reference signal (SRS),
a sum of K1 and K2 is equal to K, and in a case of a third time interval being less than a fourth time interval:
receiving the SRS from the terminal device on the K2 symbols without receiving the SRS carried on the K1 symbols,
wherein:
the third time interval is a time amount required by the terminal device to process the indication information, and
the fourth time interval is between a first time at which the terminal device receives the indication information and a second time at which the terminal device starts to send the SRS.
14. The apparatus according to claim 13 , wherein the SRS is repeatedly sent on symbols in one slot.
15. The apparatus according to claim 13 , wherein:
all of the K1 symbols are located in the first time-frequency resource.
16. The apparatus according to claim 13 , wherein the indication information is group-common signaling.
17. The apparatus according to claim 13 , wherein the indication information is an uplink cancelation indication.
18. The apparatus according to claim 13 , wherein:
at least one symbol of the K1 symbols is located in the first time-frequency resource, and other symbols of the K1 symbols are located outside the first time-frequency resource.
