Abstract
This application provides a communication method and apparatus. The method includes: implicitly indicating a quantity of time units for transmitting a data channel and a quantity of times of retransmission of the data channel by using a size of a resource for transmitting a control channel.
Claims22
A method, comprising:
- receiving, by a terminal device from a network device, a control channel;
- detecting, by the terminal device, the control channel;
- determining, by the terminal device, a size of a resource for transmitting the control channel by the network device, wherein the control channel carries a first parameter, and the first parameter is used to control transmission of data on a data channel;
- determining, by the terminal device, a quantity of times of retransmission of the data channel based on mapping relationships and the size of the resource for transmitting the control channel, wherein the mapping relationships map each control channel resource size of a plurality of control channel resource sizes to a different data channel retransmission number of a plurality of data channel retransmission numbers, wherein the plurality of control channel resource sizes are positively mapped to the plurality of data channel retransmission numbers, and wherein the mapping relationships include a first mapping relationship mapping the size of the resource for transmitting the control channel to the quantity of times of retransmission of the data channel;
- and
- receiving, by the terminal device, the data channel based on the quantity of times of retransmission of the data channel.

An apparatus, comprising:
- a receiver, configured to:
- receive a control channel from a network device, wherein the control channel carries a first parameter, and the first parameter is used to control transmission of data on a data channel;
- and
- at least one processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the at least one processor, the program including instructions for:
- detecting the control channel;
- and
- determining a size of a resource for transmitting the control channel by the network device;
- and
- determining a quantity of times of retransmission of the data channel based on mapping relationships and the size of the resource for transmitting the control channel, wherein the mapping relationships map each control channel resource size of a plurality of control channel resource sizes to a different data channel retransmission number of a plurality of data channel retransmission numbers, wherein the plurality of control channel resource sizes are positively mapped to the plurality of data channel retransmission numbers, and wherein the mapping relationships include a first mapping relationship mapping the size of the resource for transmitting the control channel to the quantity of times of retransmission of the data channel;
- and
- wherein the receiver is further configured to receive the data channel based on the quantity of times of retransmission of the data channel.

An apparatus, comprising:
- at least one processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the at least one processor, the program including instructions for:
- determining a size of a resource for transmitting a control channel, wherein the control channel carries a first parameter, the first parameter is used to control transmission of data on a data channel, and a first mapping relationship of mapping relationships exists between the size of the resource for transmitting the control channel and a quantity of times of retransmission of the data channel, wherein the mapping relationships map each control channel resource size of a plurality of control channel resource sizes to a different data channel retransmission number of a plurality of data channel retransmission numbers, and wherein the plurality of control channel resource sizes are positively mapped to the plurality of data channel retransmission numbers;
- and
- sending the control channel and the data channel.
