Abstract
Embodiments of the disclosure generally relate to feedback of a HARQ acknowledgement. A network device transmits, to a terminal device, a first trigger indicating a feedback mode of a HARQ acknowledgement. The feedback mode is selected from at least one of: a trigger mode, a timing mode, and a mixed mode. In response to successful access to an unsilenced band allocated to the HARQ acknowledgement, the network device transmits, to the terminal device, a second trigger indicating at least one target terminal device that is to feedback the HARQ acknowledgement based on the feedback mode indicated by the first trigger.
Claims4
A method performed by a user equipment (UE), the method comprising:
- receiving, from a base station, a first information in a first Downlink Control Information (DCI) corresponding to a Physical Downlink Shared Channel (PDSCH), the first information relating to a Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) information of the PDSCH;
- multiplexing, if the first information does not indicate a timing for transmitting the HARQ-ACK information and the UE receives a second information in a second DCI from the base station, the second information indicating a timing for transmitting the HARQ-ACK information, the HARQ-ACK information of the PDSCH in a Physical Uplink Control Channel (PUCCH) transmission at the timing indicated by the second information;
- and
- transmitting, to the base station, the HARQ-ACK information multiplexed in the PUCCH transmission based on the second information.
A user equipment (UE), comprising:
- a processor;
- and
- a memory, the memory containing program including instructions executable by the processor, the processor being configured to cause the UE to:
- receive, from a base station, a first information in a first Downlink Control Information (DCI) corresponding to a Physical Downlink Shared Channel (PDSCH), the first information relating to a Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) information of the PDSCH;
- multiplex, if the first information does not indicate a timing for transmitting the HARQ-ACK information and the UE receives a second information in a second DCI from the base station, the second information indicating a timing for transmitting the HARQ-ACK information, the HARQ-ACK information of the PDSCH in a Physical Uplink Control Channel (PUCCH) transmission at the timing indicated by the second information;
- and
- transmit, to the base station, the HARQ-ACK information multiplexed in the PUCCH transmission based on the second information.
