Data Transmission Method and Apparatus

A data transmission apparatus, comprising:

• a memory configured to store an instruction;
• and
• a processor coupled to the memory, the instruction causing the processor to be configured to:
• determine a redundancy time according to a delay requirement of a service, the redundancy time indicating a time used for transmitting redundant data of native data of the service, and the redundancy time being less than or equal to a time indicated by the delay requirement;
• determine a redundancy quantity indicating a quantity of times of transmitting the redundant data, the redundancy quantity being N, and the N being a positive integer;
• determine N redundancy transmission time intervals according to the redundancy time and the redundancy quantity, a total time of the N redundancy transmission time intervals being less than or equal to the redundancy time;
• and
• send the redundant data for an nth time according to an nth redundancy transmission time interval (Tp(n)) after transmitting the native data of the service and when feedback data is not received within the Tp(n), the n being 1, . . . , or N.

A non-transitory computer-readable medium storing computer instructions that, when executed by one or more processors, cause the one or more processors to:

• determine a redundancy time according to a delay requirement of a service, the redundancy time indicating a time of transmitting redundant data, the redundant data being a redundant data of native data of the service, and the redundancy time being less than or equal to a time indicated by the delay requirement;
• determine a redundancy quantity indicating a quantity of times of transmitting the redundant data, the redundancy quantity being N, and the N being a positive integer;
• determine N redundancy transmission time intervals according to the redundancy time and the redundancy quantity, a total time of the N redundancy transmission time intervals being less than or equal to the redundancy time;
• and
• transmit the redundant data for an nth time according to an nth redundancy transmission time interval (Tp(n)) after transmitting the native data of the service and when feedback data is not received within the Tp(n), and the n being 1, . . . , or N.
