example 1

[0070] Specifically, when the first information is used to indicate the ID information of the CORESET corresponding to the search space where the target fallback DCI is located, when the terminal device detects the fallback DCI on the CORESET according to the ID information of the CORESET (the fallback DCI That is, when the target fallback DCI), the terminal device feeds back the 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 CORESET indicated by the first information, it feeds back part or ACK / NACK corresponding to all HARQ processes.

example 1

[0071] Example 1: The above first indication information may indicate that the fallback DCI transmitted on the CORESET whose ID number of the CORESET is odd (or even) is the target fallback DCI.

example 2

[0072] Example 2: The above-mentioned first indication information can indicate that the ID number of the CORESET satisfies the condition of mod(CORESET ID, X)=Y (the above-mentioned X can be set according to the actual application scenario, and the present invention does not limit this) on the CORESET The transmitted fallback DCI is the target fallback DCI.

[0073] In this way, when the terminal device detects the target fallback DCI shown in the above example 1 or example 2, it can feed back the ACK / NACK corresponding to part or all of the HARQ processes on the PUCCH resource corresponding to the PDSCH scheduled by the target fallback DCI.

Abstract

The embodiment of the invention provides a determination method, terminal equipment and network equipment, relates to the technical field of communication, and aims to solve the problem of resource waste caused by the fact that ACK / NACK cannot be fed back to a base station under the condition that existing UE is busy in channel interception result. The method comprises the steps of determining whether to send second information to network equipment on a first resource or not according to first information under the condition that the terminal equipment monitors first DCI; wherein the first resource is a physical uplink control channel PUCCH resource or a physical uplink shared channel PUSCH resource corresponding to a physical downlink control channel PDCCH scheduled by the first DCI; wherein the second information is acknowledgement information ACK / negative acknowledgement information NACK corresponding to part or all of hybrid automatic repeat request (HARQ) processes. The present invention is applied to a PDSCH transmission scenario.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a determination method, terminal equipment and network equipment. Background technique [0002] At present, after receiving the Physical Downlink Shared Channel (PDSCH) sent by the base station, the user equipment (User Equipment, UE) needs to feed back acknowledgment information (Acknowledgment, ACK) / denial information (Negative ACKnowledgment, NACK), in order to Inform the base station whether the PDSCH is received correctly, and assist the base station to determine whether to retransmit the PDSCH in the future according to the ACK / NACK. [0003] In the NR-U scenario, since the UE needs to monitor the channel first when sending ACK / NACK to determine whether the channel is busy or green, if the result of the monitoring is busy, the UE will not be able to send information, and if the channel is idle, the UE will be able to Send uplink control information such as A...
