Abstract
An information transmission method and apparatus are provided. The method includes: determining, by a terminal device, a grant-free uplink GUL radio resource, where the GUL radio resource is used by the terminal device to send uplink data, and the GUL radio resource includes at least one time unit; and sending, by the terminal device in a first time unit in the at least one time unit, first feedback information for downlink transmission. Therefore, a feedback delay for downlink data can be effectively reduced.
Claims20
An information transmission method comprising:
- determining, by a terminal device, a grant-free uplink (GUL) radio resource, wherein the GUL radio resource is used by the terminal device to send uplink data, and wherein the GUL radio resource comprises at least one time unit;
- and
- sending, by the terminal device in a first time unit included in the at least one time unit, first feedback information for downlink transmission.
An information transmission apparatus comprising:
- a processing unit configured to determine a grant-free uplink (GUL) radio resource, wherein the GUL radio resource is used to send uplink data, and wherein the GUL radio resource comprises at least one time unit;
- and
- a sending unit configured to send, in a first time unit included in the at least one time unit, determined by the processing unit, first feedback information for downlink transmission.
An information transmission apparatus comprising:
- a processing unit configured to allocate a grant-free uplink (GUL) radio resource to a terminal device, wherein the GUL radio resource is used by the terminal device to send uplink data, and wherein the GUL radio resource comprises at least one time unit;
- and
- a receiving unit configured to receive first feedback information sent by the terminal device for downlink data, wherein the first feedback information is carried in a first time unit in the at least one time unit.
