The method may be applied to internet of vehicles, for example, V2X, LTE-V, or V2V, or may be applied to fields such as intelligent driving and an intelligent connected vehicle. The method includes: A first device determines a first resource and a second resource; and the first device sends or receives first data on a resource other than at least one time domain symbol on the first resource, and sends or receives control information on the second resource, when the first resource and the second resource overlap in the at least one time domain symbol; or the first device sends or receives first data on the first resource, and discards or skips receiving control information in at least one time domain symbol. ## Claims ### Claim 1 A communication method, comprising: determining, by a first device, a first resource and a second resource, wherein the first resource is used to send or receive first data, the second resource is used to send or receive control information, and the control information corresponds to second data; and upon determining that the first resource and the second resource overlap in at least one time domain symbol, performing, by the first device, first operations or second operations, wherein the first operations comprise sending or receiving, by the first device, the first data on a resource other than the at least one time domain symbol on the first resource, and sending or receiving, by the first device, the control information on the second resource; wherein the second operations comprise sending or receiving, by the first device, the first data on the first resource, and discarding or skipping receiving, by the first device, the control information in the at least one time domain symbol; and wherein the first resource is located in a first resource pool, the second resource is located in a second resource pool, and the second resource pool comprises transmission resources that are for the control information and whose period is N; and the first resource pool does not comprise a transmission resource for sending the control information, or the first resource pool comprises transmission resources that are for the control information and whose period is M, wherein M and N are positive integers, and M is greater than N. ### Claim 2 (depends on 1) The method according to claim 1, wherein performing the first operations or the second operations comprises performing the first operations upon determining that a priority of the first data is lower than a priority of the second data. ### Claim 3 (depends on 1) The method according to claim 1, wherein performing the first operations or the second operations comprises performing the second operations upon determining that a priority of the first data is higher than a priority of the second data. ### Claim 4 (depends on 1) The method according to claim 1, wherein the control information is hybrid automatic repeat request (HARQ) acknowledgement information or scheduling information indicating data transmission. ### Claim 5 (depends on 1) The method according to claim 1, wherein the first resource and the second resource are located in a same frequency band, a same carrier, or a same bandwidth part. ### Claim 6 (depends on 1) The method according to claim 1, wherein the first resource and the second resource are located in a same slot, the second resource is located in the last K symbols in the slot in which the first resource is located, and K is a positive integer greater than or equal to 1. ### Claim 7 A communication apparatus, comprising one or more processors, and a memory configure to store program instructions that, when executed by the one or more processors, cause the communications apparatus to: determine a first resource and a second resource, wherein the first resource is used to send or receive first data, the second resource is used to send or receive control information, and the control information corresponds to second data; and upon determining that the first resource and the second resource overlap in at least one time domain symbol, perform first operations or second operations, wherein the first operations comprise sending or receiving the first data on a resource other than the at least one time domain symbol on the first resource, and sending or receiving the control information on the second resource; wherein the second operations comprise sending or receiving the first data on the first resource, and discarding or skipping receiving the control information in the at least one time domain symbol; and wherein the first resource is located in a first resource pool, the second resource is located in a second resource pool, and the second resource pool comprises transmission resources that are for the control information and whose period is N; and the first resource pool does not comprise a transmission resource for sending the control information, or the first resource pool comprises transmission resources that are for the control information and whose period is M, wherein M and N are positive integers, and M is greater than N. ### Claim 8 (depends on 7) The communication apparatus according to claim 7, wherein the communication apparatus is caused to perform the first operations upon determining that a priority of the first data is lower than a priority of the second data. ### Claim 9 (depends on 7) The communication apparatus according to claim 7, wherein the communication apparatus is caused to perform the second operations upon determining that a priority of the first data is higher than a priority of the second data. ### Claim 10 (depends on 7) The communication apparatus according to claim 7, wherein the control information is hybrid automatic repeat request (HARQ) acknowledgement information or scheduling information indicating data transmission. ### Claim 11 (depends on 7) The communication apparatus according to claim 7, wherein the first resource and the second resource are located in a same frequency band, a same carrier, or a same bandwidth part. ### Claim 12 (depends on 7) The communication apparatus according to claim 7, wherein the first resource and the second resource are located in a same slot, the second resource is located in the last K symbols in the slot in which the first resource is located, and K is a positive integer greater than or equal to 1. ### Claim 13 A non-transitory computer-readable storage medium comprising instructions that, when executed by a computer, cause the computer to: determine a first resource and a second resource, wherein the first resource is used to send or receive first data, the second resource is used to send or receive control information, and the control information corresponds to second data; and upon determining that the first resource and the second resource overlap in at least one time domain symbol, perform first operations or second operations, wherein the first operations comprise sending or receiving the first data on a resource other than the at least one time domain symbol on the first resource, and sending or receiving the control information on the second resource; wherein the second operations comprise sending or receiving the first data on the first resource, and discarding or skipping receiving the control information in the at least one time domain symbol; and wherein the first resource is located in a first resource pool, the second resource is located in a second resource pool, and the second resource pool comprises transmission resources that are for the control information and whose period is N; and the first resource pool does not comprise a transmission resource for sending the control information, or the first resource pool comprises transmission resources that are for the control information and whose period is M, wherein M and N are positive integers, and M is greater than N. ### Claim 14 (depends on 13) The non-transitory computer-readable storage medium according to claim 13, wherein the computer is caused to perform the first operations upon determining that a priority of the first data is lower than a priority of the second data. ### Claim 15 (depends on 13) The non-transitory computer-readable storage medium according to claim 13, wherein the computer is caused to perform the second operations upon determining that a priority of the first data is higher than a priority of the second data. ### Claim 16 (depends on 13) The non-transitory computer-readable storage medium according to claim 13, wherein the control information is hybrid automatic repeat request (HARQ) acknowledgement information or scheduling information indicating data transmission. ### Claim 17 (depends on 13) The non-transitory computer-readable storage medium according to claim 13, wherein the first resource and the second resource are located in a same frequency band, a same carrier, or a same bandwidth part.
