Background
At present, after receiving a Physical Downlink Shared Channel (PDSCH) sent by a base station, a User Equipment (UE) needs to feed back Acknowledgement (ACK)/Negative Acknowledgement (NACK) information to inform the base station whether the PDSCH is correctly received, and the auxiliary base station determines whether to retransmit the PDSCH subsequently according to the ACK/NACK.
In the NR-U scenario, since the UE needs to perform channel sensing first when sending ACK/NACK, it is determined whether the channel is busy or not, if the sensing result is busy, the UE cannot send information, and if the channel is idle, the UE may send uplink control information such as ACK/NACK.
However, when the listening result is busy, the UE cannot send ACK/NACK to the base station, so that the base station cannot know whether to retransmit the PDSCH, and the base station can only subsequently retransmit all the previously sent PDSCHs, thereby causing resource waste.

Fig. 2 is a schematic flow chart of a determination method according to an embodiment of the present invention, and as shown in fig. 2, the determination method may include the following steps:
step 201: the network device generates a first DCI.
Step 202: the network device transmits the first DCI to the terminal device.
The network device in the embodiment of the present invention may be a network device in the communication system shown in fig. 1, for example, a base station; the terminal device in the embodiment of the present invention may be a terminal in the communication system shown in fig. 1.

Step 203: and under the condition that the terminal equipment monitors the first DCI, the terminal equipment determines whether to send second information to the network equipment on the first resource or not according to the first information.
Optionally, in this embodiment of the present invention, the first information may be predefined, that is, specified by a protocol.
Optionally, in this embodiment of the present invention, the first information is configured by the network device for the terminal device.
Illustratively, as shown in fig. 3, before step 201 described above, the terminal device needs to configure the first information for the terminal device. Specifically, the method further comprises a step a 1:
step A1: the network device sends the first information to the terminal device.
With reference to step 201a, before step 203, or before the terminal device monitors the first DCI, the method further includes step a 2:
step A2: the terminal device receives first information from the network device.
In this embodiment of the present invention, the first resource is a PUCCH resource or a PUSCH resource corresponding to a PDSCH scheduled by the first DCI. The second information is ACK/NACK corresponding to part or all of the HARQ processes, that is, the second information is ACK/NACK corresponding to each HARQ process in part or all of the HARQ processes.
In this embodiment of the present invention, the first information is used to indicate a transmission condition of the second information, that is, the first information is used to indicate a transmission condition of the terminal device for transmitting the second information to the network device.
Optionally, in this embodiment of the present invention, the first information is used to indicate a target fallback DCI. Specifically, the first information is used to instruct the terminal device to send the second information to the network device when the target fallback DCI is monitored, that is, the sending conditions are as follows: and the terminal equipment monitors the target backspacing DCI.
Further optionally, in an embodiment of the present invention, the first information is used to indicate at least one of the following: information of a CORESET corresponding to a search space where the target fallback DCI is located, information of a Control Channel Element (CCE) of a Physical Downlink Control Channel (PDCCH) carrying the target fallback DCI, information of a time slot where the PDCCH carrying the target fallback DCI is located, and aggregation level information used by the target fallback DCI.
In one example, the first information includes at least one of: information of a CORESET corresponding to a search space in which the target fallback DCI is located (for example, ID number information of the CORESET), information of a search space in which the target fallback DCI is located (for example, ID number information of the search space), information of a starting CCE of a PDCCH carrying the target fallback DCI, information of a slot in which the PDCCH carrying the target fallback DCI is located, and aggregation level information used by the target fallback DCI.
Generally, an aggregation level refers to how many CCEs DCI is carried on, and the aggregation level may be, but is not limited to, 1, 2, 4, 8, 16, etc., for example, an aggregation level of 2 refers to that DCI is carried on 2 CCEs.
Optionally, in an embodiment of the present invention, after step 203, the method further includes:
step 203 a: and the terminal equipment sends the second information to the network equipment on the first resource according to the size of the identifier of the HARQ process under the condition that the terminal equipment determines to send the second information to the network equipment on the first resource according to the first information.
Illustratively, if the second information includes ACKs/NACKs corresponding to all HARQ processes, the terminal device sorts the identifiers of all HARQ processes in order from large to small, and then sequentially feeds back the ACKs/NACKs of each HARQ process in all HARQ processes to the network device on the first resource according to the order; and if the second information comprises ACK/NACK corresponding to part of the HARQ processes, the terminal equipment sorts the identifiers of the part of the HARQ processes according to the sequence from large to small, and then feeds back the ACK/NACK of each HARQ process in the part of the HARQ processes to the network equipment on the first resource in sequence according to the sequence. At this time, the terminal device does not feed back the number of bits of the ACK/NACK determined according to the semi-static codebook or dynamic codebook previously configured by the network device.
It should be noted that, in the embodiment of the present invention, when the second information is ACK/NACK corresponding to a part of HARQ processes, the part of HARQ processes are configured to the terminal device by the network device, for example, the network device configures an identifier of the part of HARQ processes for the terminal device.
Optionally, in this embodiment of the present invention, when the first information is used to indicate a target fallback DCI, step 203 specifically includes the following steps:
step 203b 1: and the terminal equipment determines whether the first DCI is the target backspacing DCI or not according to the first information.
Step 203b 2: and if the first DCI is the target backspacing DCI, the terminal equipment determines to send second information to the network equipment on the first resource.
The above-described processes of step 203b1 and step 203b2 will be described below with five examples:
example 1:
specifically, under the condition that the first information is used to indicate ID information of a core set corresponding to a search space where the target fallback DCI is located, when the terminal device detects the fallback DCI (the fallback DCI is the target fallback DCI) on the core set according to the ID information of the core set, the terminal device feeds back ACK/NACK corresponding to part or all HARQ processes to the network device, that is, when the terminal device detects the fallback DCI on the core set indicated by the first information, the terminal device feeds back ACK/NACK corresponding to part or all HARQ processes.
Example 1: the first indication information may indicate that the fallback DCI transmitted on the CORESET with the odd (or even) ID number of the CORESET is the target fallback DCI.
Example 2: the first indication information may indicate that the fallback DCI transmitted on the core set, whose ID number of the core set satisfies a condition of mod (core ID, X) ═ Y (X may be set according to a practical application scenario, and the present invention is not limited thereto), is the target fallback DCI.
Thus, when the terminal device monitors the target fallback DCI shown in example 1 or example 2, ACK/NACK corresponding to part or all of the HARQ processes may be fed back on the PUCCH resource corresponding to the PDSCH scheduled by the target fallback DCI.
Example 2:
specifically, in the case that the first information is used for indicating ID information of a search space in which target fallback DCI is located, when terminal equipment detects fallback DCI (the fallback DCI is the target fallback DCI) on the search space, the terminal equipment feeds back ACK/NACK corresponding to part or all HARQ processes to network equipment, that is, when the terminal equipment detects the fallback DCI on the search space indicated by the first information, the terminal equipment feeds back ACK/NACK corresponding to part or all HARQ processes.
Example 3: the first indication information may indicate that fallback DCI transmitted on a search space with an odd or even ID number of the search space is target fallback DCI. Thus, when the terminal device monitors the target fallback DCI, the terminal device can feed back ACK/NACK corresponding to part or all of HARQ processes on PUCCH resources corresponding to PDSCH scheduled by the target fallback DCI.
Example 3:
specifically, under the condition that the first information is used to indicate starting CCE information of a PDCCH where the target fallback DCI is located, when the terminal device detects the fallback DCI (the fallback DCI is the target fallback DCI) on the starting CCE information, the terminal device feeds back ACK/NACK corresponding to part or all of the HARQ processes to the network device, that is, when the terminal device detects the fallback DCI on the starting CCE information indicated by the first information, the terminal device feeds back ACK/NACK corresponding to part or all of the HARQ processes.
Example 4: the first indication information may indicate that the fallback DCI transmitted on the PDCCH whose starting CCE of the PDCCH is odd or even is the target fallback DCI. Thus, when the terminal device monitors the target fallback DCI, the terminal device can feed back ACK/NACK corresponding to part or all of HARQ processes on PUCCH resources corresponding to PDSCH scheduled by the target fallback DCI.
Example 4:
specifically, under the condition that the first information is used to indicate slot information where the target fallback DCI is located, when the terminal device detects the fallback DCI (the fallback DCI is the target fallback DCI) on the slot, the terminal device feeds back ACK/NACK corresponding to part or all of the HARQ processes to the network device, that is, when the terminal device detects the fallback DCI on the starting CCE information indicated by the first information, the terminal device feeds back ACK/NACK corresponding to part or all of the HARQ processes.
Example 5: the first indication information may indicate that the fallback DCI transmitted on the slot with the odd or even slot is the target fallback DCI. Thus, when the terminal device monitors the target fallback DCI, the terminal device can feed back ACK/NACK corresponding to part or all of HARQ processes on PUCCH resources corresponding to PDSCH scheduled by the target fallback DCI.
Example 5:
specifically, under the condition that the first information is used to indicate aggregation level information used by the target fallback DCI, when the terminal device detects the fallback DCI (the fallback DCI is the target fallback DCI) according to the aggregation level information, the terminal device feeds back ACK/NACK corresponding to part or all of the HARQ processes to the network device, that is, when the terminal device detects the fallback DCI on the starting CCE information indicated by the first information, the terminal device feeds back ACK/NACK corresponding to part or all of the HARQ processes.
Example 6: the first indication information may indicate that the DCI with the aggregation level of 4 is the target fallback DCI. Thus, when the terminal device monitors the target fallback DCI, the terminal device can feed back ACK/NACK corresponding to part or all of HARQ processes on PUCCH resources corresponding to PDSCH scheduled by the target fallback DCI.
In addition, in the embodiment of the present invention, the terminal device may also directly monitor the target fallback DCI according to the first information, and after monitoring the target fallback DCI, send ACK/NACK corresponding to part or all of the HARQ processes to the network device on the PUCCH resource or PUSCH resource corresponding to the PDSCH scheduled by the target fallback DCI.
In the determining method provided in the embodiment of the present invention, when the terminal device monitors the first DCI, the terminal device determines, according to the indication of the first information, whether to send the second information (i.e., ACK/NACK corresponding to a part or all of HARQ processes) to the network device on the first resource (i.e., PUCCH resource or PUSCH resource corresponding to PDSCH scheduled by the first DCI), and since the first information defines the sending condition of the second information, the terminal device can avoid the problem of resource waste caused by that ACK/NACK corresponding to the HARQ process cannot be fed back to the network device when the channel sensing result of the terminal device is busy, and can improve the resource utilization rate.
