Abstract

The embodiments of the present disclosure provide a method for transmitting data, a base station, a terminal, a system, and a computer-readable storage medium. In the method for transmitting data, a base station sends control information to a terminal over a PDCCH, starts to receive a feedback signal which is sent by the terminal after decoding the control information, and sends information to the terminal after receiving the feedback signal.

First claim

What is claimed is:

1. A method for transmitting data performed by a base station, the method comprising:
sending control information to a terminal over a Physical Downlink Control Channel (PDCCH), wherein sending the control information to the terminal over the PDCCH comprises: in responsive to detecting that the number of error Physical Downlink Shared Channel (PDSCH) packets reported by the terminal exceeds a preset threshold, sending the control information to the terminal over the PDCCH;
starting to receive a feedback signal which is sent by the terminal after decoding the control information; and
in responsive to receiving a second indication signal from the terminal within a first preset time, or in responsive to receiving no signal within the first preset time, resending control information to the terminal over the PDCCH after a second preset time, wherein the second indication signal is a signal indicating that the terminal decodes the control information unsuccessfully.

2. The method for transmitting data according to claim 1 , wherein sending the control information to the terminal over the PDCCH further comprises:
in responsive to detecting that an application scenario of the terminal is a preset application scenario, sending the control information to the terminal over the PDCCH.

3. The method for transmitting data according to claim 1 , further comprising:
in responsive to receiving a first indication signal sent by the terminal, sending data information to the terminal over a Physical Downlink Shared Channel (PDSCH), wherein the first indication signal is a signal indicating that the terminal decodes the control information successfully.

4. The method for transmitting data according to claim 3 , wherein in responsive to receiving the first indication signal sent by the terminal, sending the data information to the terminal over the PDSCH further comprises: in a case of receiving a third indication signal, sending the control information to the terminal over the PDCCH, wherein the third indication signal is a signal indicating that the terminal fails to decode the data information which is sent, in responsive to receiving the first indication signal sent by the terminal, to the terminal over the PDSCH.

5. The method for transmitting data according to claim 4 , wherein in the case of receiving the third indication signal, sending the control information to the terminal over the PDCCH comprises:
in responsive to receiving the third indication signal from the terminal within the first preset time, immediately scheduling the control information previously sent to the terminal and resending the control information to the terminal over the PDCCH.

6. The method for transmitting data according to claim 4 , wherein in the case of receiving the third indication signal, sending the control information to the terminal over the PDCCH comprises:
in responsive to receiving the third indication signal from the terminal within the first preset time, resending the control information to the terminal over the PDCCH after a second preset time.

7. The method for transmitting data according to claim 1 , wherein the feedback signal is a signal sent by the terminal over a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

8. A method for transmitting data performed by a base station, the method comprising:
sending control information to a terminal over a Physical Downlink Control Channel (PDCCH), wherein sending the control information to the terminal over the PDCCH comprises: in responsive to detecting that the number of error Physical Downlink Shared Channel (PDSCH) packets reported by the terminal exceeds a preset threshold, sending the control information to the terminal over the PDCCH;
starting to receive a feedback signal which is sent by the terminal after decoding the control information; and
in responsive to receiving the second indication signal from the terminal within a first preset time, or in responsive to receiving no signal within the first preset time, immediately scheduling control information previously sent to the terminal and resending the control information to the terminal over the PDCCH, wherein the second indication signal is a signal indicating that the terminal decodes the control information unsuccessfully.

9. A method for transmitting data performed by a terminal, the method comprising:
in responsive to receiving control information sent by a base station over a Physical Downlink Control Channel (PDCCH), decoding the control information, wherein the control information is sent by the base station to the terminal over the PDCCH in responsive to detecting that the number of error Physical Downlink Shared Channel (PDSCH) packets reported by the terminal exceeds a preset threshold;
sending a feedback signal to the base station after decoding the control information, wherein sending the feedback signal to the base station after decoding the control information comprises: sending a second indication signal or sending no signal to the base station in a case where the terminal decodes the control information unsuccessfully, so as to trigger the base station to resend control information to the terminal over the PDCCH after a second preset time in responsive to receiving the second indication signal from the terminal within a first preset time or in responsive to receiving no signal within the first preset time, wherein the second indication signal is a signal indicating that the terminal decodes the control information unsuccessfully; and
receiving the control information resent by the base station over the PDCCH.

10. The method for transmitting data according to claim 9 , wherein sending the feedback signal to the base station after decoding the control information further comprises: sending a first indication signal to the base station in a case of decoding the control information successfully.

11. The method for transmitting data according to claim 10 , wherein sending the first indication signal to the base station in the case of decoding the control information successfully further comprises: decoding data information sent by the base station over a Physical Downlink Shared Channel (PDSCH), and sending a third indication signal to the base station in a case of decoding the data information unsuccessfully.

12. The method for transmitting data according to claim 9 , wherein sending the feedback signal to the base station after decoding the control information comprises: sending the feedback signal to the base station over a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH) after decoding the control information.

13. A method for transmitting data performed by a terminal, the method comprising:
in responsive to receiving control information sent by a base station over a Physical Downlink Control Channel (PDCCH), decoding the control information, wherein the control information is sent by the base station to the terminal over the PDCCH in responsive to detecting that the number of error Physical Downlink Shared Channel (PDSCH) packets reported by the terminal exceeds a preset threshold;
sending a feedback signal to the base station after decoding the control information, wherein sending the feedback signal to the base station after decoding the control information comprises: sending a second indication signal or sending no signal to the base station in a case where the terminal decodes the control information unsuccessfully, so as to trigger the base station to immediately schedule control information previously sent to the terminal and resend the control information to the te
