Abstract

A data transmission method includes: receiving, by a network device, uplink data sent by a terminal device based on a grant-free manner; and sending, by the network device, a response message for the uplink data to the terminal device according to a type of the response message for the uplink data, where the type of the response message for the uplink data is a first response type or a second response type, the first response type is that each time the terminal device sends the uplink data, the network device sends the response message for the uplink data to the terminal device once, and the second response type is that after the terminal device sends the uplink data for a plurality of times, the network device sends, to the terminal device once, the response message for the uplink data that is sent for the plurality of times.

Dependent claims

A data transmission method, implemented by a terminal device, wherein the data transmission method comprises:

receiving first indication information from a network device;
determining a type of a response message for uplink data according to the first indication information, wherein the type of the response message for the uplink data is a first response type or a second response type, wherein the first response type is that each time the terminal device sends the uplink data, the network device sends the response message for the uplink data to the terminal device once, and wherein the second response type is that, after the terminal device sends the uplink data a plurality of times, the network device sends the response message to the terminal device once for the uplink data that is sent for the plurality of times;
sending the uplink data to the network device based on a grant-free manner;
and
receiving, according to the type of the response message for the uplink data, the response message from the network device for the uplink data.

2 more elements

A data transmission apparatus, comprising:

a receiver configured to receive uplink data from a terminal device based on a grant-free manner;
and
a transmitter coupled to the receiver and configured to:
send first indication information to the terminal device before receiving the uplink data from the terminal device based on the grant-free manner, wherein the first indication information is for determining a type of a response message for the uplink data;
and
send the response message for the uplink data to the terminal device according to the type of the response message for the uplink data, wherein the type of the response message for the uplink data is a first response type or a second response type, wherein the first response type is that each time the terminal device sends the uplink data, the data transmission apparatus sends the response message for the uplink data to the terminal device once, and wherein the second response type is that, after the terminal device sends the uplink data for a plurality of times, the data transmission apparatus sends the response message to the terminal device once for the uplink data that is sent for the plurality of times.

3 more elements

A data transmission apparatus, comprising:

a processor configured to determine a type of a response message for uplink data according to first indication information, wherein the type of the response message for the uplink data is a first response type or a second response type, wherein the first response type is that each time the data transmission apparatus sends the uplink data, a network device sends the response message for the uplink data to the data transmission apparatus once, and wherein the second response type is that, after the data transmission apparatus sends the uplink data for a plurality of times, the network device sends the response message to the data transmission apparatus once for the uplink data that is sent for the plurality of times;
a transmitter coupled to the processor and configured to send the uplink data to the network device based on a grant-free manner;
and
a receiver coupled to the processor and configured to:
receive the first indication information from the network device before the processor determines the type of the response message for the uplink data;
and
receive, according to the type of the response message for the uplink data, the response message from the network device for the uplink data.
