A data communication method, applied to a transmitting terminal, comprising: notifying (102, 302) connection information to a preset second receiving terminal after establishing (101, 301) a wireless communication connection with a preset first receiving terminal; wherein the connection information comprises information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal, wherein the information of the communication channel comprises a communication frequency of the communication channel; wherein the connection information is used to instruct the second receiving terminal to monitor communication data in the communication channel, to enable the second receiving terminal to transmit data required to be transmitted to the first receiving terminal to the communication channel when the communication data is known after monitoring by the second receiving terminal, such that data is transmitted from the transmitting terminal and the second receiving terminal to the first receiving terminal through a same communication channel; wherein a first time period for the transmitting terminal to transmit data in the communication channel does not overlap a second time period for the second receiving terminal to transmit data in the communication channel; and wherein the first time period and the second time period are acquired through a preset time slice division, and the preset time slice is a time slice predetermined for the first receiving terminal to receive data, wherein after the notifying the connection information to the preset second receiving terminal, the method further comprises: transmitting data to the first receiving terminal through the communication channel in the first time period; wherein the connection information is used to instruct the second receiving terminal to monitor data transmitted from the transmitting terminal in the communication channel, to enable the second receiving terminal to transmit data required to be transmitted to the first receiving terminal to the communication channel within the second time period when the data transmitted from the transmitting terminal is known after monitoring by the second receiving terminal; and wherein the data required to be transmitted to the first receiving terminal is used to indicate whether the data transmitted from the transmitting terminal and known after monitoring by the second receiving terminal is correct. notifying (102, 302) connection information to a preset second receiving terminal after establishing (101, 301) a wireless communication connection with a preset first receiving terminal; wherein the connection information comprises information of a communication channel for performing wireless communication between the transmitting terminal and the first receiving terminal, wherein the information of the communication channel comprises a communication frequency of the communication channel;

and wherein the data required to be transmitted to the first receiving terminal is used to indicate whether the data transmitted from the transmitting terminal and known after monitoring by the second receiving terminal is correct. transmitting data to the first receiving terminal through the communication channel in the first time period; wherein the connection information is used to instruct the second receiving terminal to monitor data transmitted from the transmitting terminal in the communication channel, to enable the second receiving terminal to transmit data required to be transmitted to the first receiving terminal to the communication channel within the second time period when the data transmitted from the transmitting terminal is known after monitoring by the second receiving terminal; and wherein the data required to be transmitted to the first receiving terminal is used to indicate whether the data transmitted from the transmitting terminal and known after monitoring by the second receiving terminal is correct.
