Abstract
Embodiments of this application provide a data transmission method, a terminal device, and a network device. The method includes: receiving, by a terminal device, a first indication sent by a network device; receiving, by the terminal device, downlink data based on the first indication, and generating feedback information of the downlink data; receiving, by the terminal device, a second indication sent by the network device, where the second indication indicates a start location of an uplink time unit; determining, by the terminal device based on the first indication and the second indication, a resource location for sending the feedback information; and sending, by the terminal device, the feedback information at the resource location.
Claims21
A data transmission method, comprising:
- receiving, by a terminal device, a first indication sent by a network device;
- receiving, by the terminal device, downlink data based on the first indication;
- generating, by the terminal device, feedback information of the downlink data;
- receiving, by the terminal device, a second indication sent by the network device, wherein the second indication indicates a start location of an uplink time unit;
- starting, by the terminal device, a first timer when the second indication is received;
- during running of the first timer, refraining, by the terminal device, from monitoring a downlink physical channel;
- determining, by the terminal device based on the first indication and the second indication, a resource location for sending the feedback information;
- and
- sending, by the terminal device, the feedback information at the resource location.
A data transmission method, comprising:
- sending, by a network device, a first indication to a terminal device, wherein the first indication is used by the terminal device to receive downlink data based on the first indication and generate feedback information of the downlink data;
- after obtaining an unlicensed channel, sending, by the network device, a second indication to the terminal device, wherein the second indication indicates a start location of an uplink time unit, wherein the second indication triggers the terminal device to start a first timer, and during running of the first timer, the terminal device refrains from monitoring a downlink physical channel;
- and
- receiving, by the network device, the feedback information sent by the terminal device at a resource location, wherein the resource location is determined by the terminal device based on the first indication and the second indication.
A data transmission device, comprising at least one processor and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor that cause the data transmission device to:
- receive first indication sent by a network device;
- receive downlink data based on the first indication;
- generate feedback information of the downlink data;
- receive a second indication sent by the network device, wherein the second indication indicates a start location of an uplink time unit;
- start a first timer when the second indication is received;
- during running of the first timer, refrain from monitoring a downlink physical channel;
- determine, based on the first indication and the second indication, a resource location for sending the feedback information;
- and
- sending the feedback information at the resource location.
A data transmission device, comprising at least one processor and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor that cause the data transmission device to:
- send a first indication to a terminal device, wherein the first indication is used by the terminal device to receive downlink data based on the first indication and generate feedback information of the downlink data;
- after obtaining an unlicensed channel, send a second indication to the terminal device, wherein the second indication indicates a start location of an uplink time unit, wherein the second indication triggers the terminal device to start a first timer, and during running of the first timer, the terminal device refrains from monitoring a downlink physical channel;
- and
- receive, the feedback information sent by the terminal device at a resource location, wherein the resource location is determined by the terminal device based on the first indication and the second indication.
A non-transitory computer-readable storage medium, comprising a program, wherein when being executed by at least one processor, the program instructs the at least one processor to perform operations comprising:
- receiving first indication sent by a network device;
- receiving downlink data based on the first indication;
- generating feedback information of the downlink data;
- receiving a second indication sent by the network device, wherein the second indication indicates a start location of an uplink time unit;
- starting a first timer when the second indication is received;
- during running of the first timer, refraining from monitoring a downlink physical channel;
- determining, based on the first indication and the second indication, a resource location for sending the feedback information;
- and
- sending the feedback information at the resource location.
A non-transitory computer-readable storage medium, comprising a program, wherein when being executed by at least one processor, the program instructs the at least one processor to perform operations comprising:
- sending a first indication to a terminal device, wherein the first indication is used by the terminal device to receive downlink data based on the first indication and generate feedback information of the downlink data;
- after obtaining an unlicensed channel, sending a second indication to the terminal device, wherein the second indication indicates a start location of an uplink time unit, wherein the second indication triggers the terminal device to start a first timer, and during running of the first timer, the terminal device refrains from monitoring a downlink physical channel;
- and
- receiving the feedback information sent by the terminal device at a resource location, wherein the resource location is determined by the terminal device based on the first indication and the second indication.
