In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

In some embodiments, a terminal receives downlink control information (downlink control information, DCI) sent by a network device, where the DCI is used to instruct the terminal to receive downlink data through a DCI scheduled physical downlink shared channel (physical downlink shared channel, PDSCH) and send uplink control information through a DCI scheduled physical uplink control channel (physical uplink control channel, PUCCH). After receiving data through the PDSCH scheduled by DCI, the terminal needs to perform HARQ-ACK feedback on whether the received data is successful or not. Wherein a HARQ-ACK information bit of 0 indicates NACK for indicating a data connection failure; a HARQ-ACK information bit of 1 indicates ACK for indicating successful data reception. Wherein either ACK or NACK is referred to as HARQ-ACK information.

When the terminal device receives multiple DCIs, the terminal device needs to perform HARQ-ACK feedback for each downlink data, for example, the HARQ-ACK information bits are X bits, and the X HARQ-ACK information bits form a HARQ-ACK codebook.

In some embodiments, the type of HARQ-ACK codebook may be different, the type of HARQ-ACK codebook including at least one of:

a first type of HARQ-ACK codebook (type 1HARQ-ACK codebook);

A second type of HARQ-ACK codebook (type 2HARQ-ACK codebook);

a third type of HARQ-ACK codebook (type 3HARQ-ACK codebook).

In some embodiments, the first type of HARQ-ACK codebook (type 1HARQ-ACK codebook) may be referred to as a semi-static codebook (semi-static HARQ-ACK codebook).

The construction principle of the first type HARQ-ACK codebook is as follows: in the uplink time slot, the terminal feeds back the HARQ of the PDSCH of the corresponding downlink time slot according to the indication of the K1 set. The HARQ corresponding to the transmitted PDSCH is included, the true ACK or NACK is fed back, and the HARQ which has the PDSCH transmission opportunity but does not have the actual PDSCH data transmission is also included, and the NACK is fed back. And then ordering the HARQ in the carrier according to time sequence and then according to the rule of carrier ordering to form a first type HARQ-ACK codebook.

The protocol is predefined or the base station is preconfigured with a feedback window containing a plurality of time slots, and when the HARQ-ACK feedback is needed by channels in the window, the terminal feeds back the HARQ-ACK information corresponding to all preconfigured channels in the feedback window.

In some embodiments, the second type of HARQ-ACK codebook (type 2HARQ-ACK codebook) may be referred to as a dynamic codebook (dynamic HARQ-ACK codebook).

The construction principle of the second type of HARQ-ACK codebook is as follows: in actual data transmission, the UE may miss DCI transmitted by the base station through the PDCCH. For example, a base station may send a certain DCI to a UE, but the UE does not receive the DCI, or does not decode the DCI correctly, which may result in one less bit (bit) of HARQ information that the UE feeds back to the base station. For example, the base station transmits 3 DCIs to the UE, and HARQ information corresponding to the 3 DCIs is 3 bits. However, for some reasons, the UE may miss one DCI and the feedback HARQ information may be only 2 bits. However, the base station does not know that the UE does not receive the DCI, which may cause the UE and the base station to be inconsistent in understanding the load size of HARQ information. The base station still splits and decodes the received data according to the expected load size of the HARQ information. Resulting in subsequent HARQ information bits and even subsequent decoding errors of other types of uplink control information (uplink control information, UCI).

To assist the UE in finding missed DCI, if feedback of PDSCH scheduled by multiple DCIs points to the same HARQ codebook, the base station may introduce a downlink allocation index (downlink assignment index, DAI) into these DCIs, to indicate what DCI the current DCI is, called counting DAI (C-DAI). For the case of DCI missed detection, in the case of multiple carriers, the concept of total DAI (T-DAI) is also introduced, which is used to indicate the number of DCIs on all carriers up to the current time.

And the terminal feeds back the HARQ-ACK to the actually scheduled downlink channel according to the actual downlink scheduling condition of the base station.

In some embodiments, the third type of HARQ-ACK codebook (type 3HARQ-ACK codebook) may be referred to as a one-shot HARQ-ACK feedback) 0.

The third type of HARQ-ACK codebook is constructed in principle: ordering the HARQ-ACK information according to the indication of the HARQ process identification (HARQ process ID) domain.

The terminal feeds back the HARQ-ACK to all the HARQ processes configured by the base station at one time, or feeds back the HARQ-ACK to a part of the pre-configured HARQ processes in the enhanced Type3 codebook.

In some embodiments, how HARQ-ACK feedback is performed for PDSCH may be agreed in the protocol.

In some embodiments, when a medium access control (medium access control, MAC) Control Element (CE) is used to carry an activation instruction or a deactivation instruction (the activation instruction is used to activate a cell discontinuous reception mode and/or a cell discontinuous transmission mode, and the deactivation instruction is used to deactivate the cell discontinuous reception mode and/or the cell discontinuous transmission mode), how to perform HARQ-ACK feedback may be agreed in the protocol, and the HARQ-ACK feedback manner may be the same as the HARQ-ACK feedback manner for PDSCH.

In view of the fact that, in order to guarantee reliability of DCI carrying activation information or deactivation information, HARQ-ACK feedback is required for the DCI, but there is no scheme for HARQ-ACK feedback for the DCI, a scheme for HARQ-ACK feedback for the DCI needs to be provided.

23. The method of claim 16, wherein the method further comprises:

and sending second configuration information, wherein the second configuration information is used for configuring the HARQ-ACK codebook to be a second type HARQ-ACK codebook.

24. The method of claim 23, wherein the receiving HARQ-ACK information for the DCI comprises:

receiving HARQ-ACK information of the DCI under the condition that the DCI bears a downlink allocation index DAI;

25. The method of claim 23 or 24, wherein the receiving HARQ-ACK information for the DCI comprises:

receiving HARQ-ACK information of the DCI under the condition that the DCI does not bear DAI;

26. The method of claim 23 or 24, wherein the HARQ-ACK information not receiving the DCI comprises:

And if the DCI does not bear the DAI, not receiving the HARQ-ACK information of the DCI.

27. The method of claim 15, wherein the method further comprises:

and sending third configuration information, wherein the third configuration information is used for configuring the HARQ-ACK codebook to be a third type HARQ-ACK codebook.

28. The method of claim 27, wherein the receiving HARQ-ACK information for the DCI comprises:

receiving HARQ-ACK information of the DCI under the condition that the DCI carries the HARQ process identifier;

29. The method of claim 27 or 28, wherein the receiving HARQ-ACK information for the DCI comprises:

receiving HARQ-ACK information of the DCI under the condition that the DCI does not bear the HARQ process identification;

30. The method of any one of claims 27 or 28, wherein the not receiving HARQ-ACK information for the DCI comprises:

and under the condition that the DCI does not bear the HARQ process identification, not receiving the HARQ-ACK information of the DCI.

31. A communication method for a communication system, the method comprising:

the terminal receives the DCI;

32. A first communication device, the device comprising:

33. A second communication device, the device comprising:

34. A communication device includes a processor and a memory, wherein,

one or more processors;

wherein the processor is configured to invoke instructions to cause the communication device to perform the communication method of any of claims 1-15, 16-30.

35. A communication system comprising a terminal configured to implement the communication method of any of claims 1-15 and a network device configured to implement the communication method of any of claims 16-30.

36. A storage medium storing instructions which, when executed on a communications device, cause the communications device to perform the method of any one of claims 1-15, 16-30.
