Harq-Based Transmission Method and Apparatus

A hybrid automatic repeat request (HARQ)-based transmission method, comprising:

• sending, by a terminal device, a service request to a core network device by using a network device;
• receiving, by the terminal device, a HARQ configuration parameter that is configured for a service of the service request and that is sent by the network device;
• and
• configuring, by the terminal device, the HARQ configuration parameter for the service of the service request, and performing data transmission and retransmission with the network device based on the HARQ configuration parameter.

A hybrid automatic repeat request (HARQ)-based transmission apparatus, comprising:

• a transmitter, the transmitter configured to send a service request to a core network device by using a network device;
• a receiver, the receiver configured to receive a HARQ configuration parameter that is configured for a service of the service request and that is sent by the network device;
• and
• a least one processor, the at least one processor configured to:
• configure the HARQ configuration parameter for the service of the service request;
• and
• perform data transmission and retransmission with the network device based on the HARQ configuration parameter.
