Abstract
The present application relates to the field of wireless communication, and disclosed thereby are a method, apparatus and system for transmitting data. The method comprises flexibly configuring HARQ feedback in a HARQ mechanism of a terminal according to RTT of a wireless signal. Since the HARQ feedback of the terminal may be selectively turned on or off, unnecessary burdens are prevented from being created for the terminal.
Claims15
A method for transmitting data, applied to a terminal, and comprising:
- setting a hybrid automatic repeat request HARQ feedback of the terminal to be in an enabled state or a disabled state according to a round trip time RTT of a wireless signal,
- wherein the enabled state is a state in which an acknowledgement ACK or a negative acknowledgement NACK is fed back, and the disabled state is a state in which neither the ACK nor the NACK is fed back,
- wherein the setting the HARQ feedback of the terminal to be in the enabled state or the disabled state according to the RTT of the wireless signal comprises:
- receiving target signaling, wherein the target signaling is generated by the network side device according to the RTT of the wireless signal, and
- setting the HARQ feedback of the terminal to be in the enabled state or the disabled state according to the target signaling;
- wherein the target signaling is used to instruct to set HARQ feedback of each HARQ process among all of a plurality of HARQ processes used by each service type received by the terminal to be in the enabled state or the disabled state;
- and
- wherein receiving the target signaling comprises:
- receiving first signaling, wherein the first signaling is used to instruct to switch the HARQ feedback of the terminal from the disabled state to the enabled state;
- and
- receiving second signaling, wherein the second signaling is used to instruct to switch the HARQ feedback of the terminal from the enabled state to the disabled state,
- wherein the first signaling and the second signaling are both generated by the network side device according to the RTT.

A method for transmitting data, applied to a network side device, and comprising:
- setting a HARQ feedback of the network side device to be in an enabled state or a disabled state according to a RTT of a wireless signal,
- wherein the enabled state is a state in which an ACK or a NACK fed back by a terminal is received, and the disabled state is a state in which neither the ACK nor the NACK is fed back by the terminal,
- wherein the method further comprises:
- generating and sending target signaling according to the RTT;
- wherein the target signaling is used to set the HARQ feedback of the terminal to be in the enabled state or the disabled state;
- wherein the target signaling is used to instruct to set HARQ feedback of each HARQ process among all of a plurality of HARQ processes used by each service type received by the terminal to be in the enabled state or the disabled state;
- and
- wherein sending the target signaling comprises:
- sending first signaling, wherein the first signaling is used to instruct to switch the HARQ feedback of the terminal from the disabled state to the enabled state;
- and
- sending second signaling, wherein the second signaling is used to instruct to switch the HARQ feedback of the terminal from the enabled state to the disabled state,
- wherein the first signaling and the second signaling are both generated by the network side device according to the RTT.
9 more elements
A terminal, comprising a processor and a memory, wherein the memory stores at least one instruction, and the at least one instruction is configured to be executed by the processor to implement a method for transmitting data comprising:
- setting a hybrid automatic repeat request HARQ feedback of the terminal to be in an enabled state or a disabled state according to a round trip time RTT of a wireless signal,
- wherein the enabled state is a state in which an acknowledgement ACK or a negative acknowledgement NACK is fed back, and the disabled state is a state in which neither the ACK nor the NACK is fed back,
- wherein the setting the HARQ feedback of the terminal to be in the enabled state or the disabled state according to the RTT of the wireless signal comprises:
- receiving target signaling, wherein the target signaling is generated by the network side device according to the RTT of the wireless signal, and
- setting the HARQ feedback of the terminal to be in the enabled state or the disabled state according to the target signaling;
- wherein the target signaling is used to instruct to set HARQ feedback of each HARQ process among all of a plurality of HARQ processes used by each service type received by the terminal to be in the enabled state or the disabled state;
- and
- wherein receiving the target signaling comprises:
- receiving first signaling, wherein the first signaling is used to instruct to switch the HARQ feedback of the terminal from the disabled state to the enabled state;
- and
- receiving second signaling, wherein the second signaling is used to instruct to switch the HARQ feedback of the terminal from the enabled state to the disabled state,
- wherein the first signaling and the second signaling are both generated by the network side device according to the RTT.
