Method for determining feedback information, terminal device, and network device

A transmit end device, comprising:

• a transceiver configured to:
• send to a terminal device a set of hybrid automatic repeat request (HARQ) time sequence K1 values and time unit format information via one or more radio resource control (RRC) signalings, wherein a HARQ time sequence K1 value of the set of HARQ time sequence K1 values is a time relationship between a time unit of a physical downlink shared channel (PDSCH) and a time unit of a physical uplink control channel (PUCCH), or wherein a HARQ time sequence K1 value of the set of HARQ time sequence K1 values is a time relationship between a time unit of a PDSCH and a time unit of a physical uplink shared channel (PUSCH);
• and
• receive from the terminal device, HARQ feedback information, wherein a quantity of HARQ feedback information bits is associated with the set of HARQ time sequence K1 values and the time unit format information.

A device in a wireless communication network, comprising:

• a processor;
• and
• a memory storing program instructions, that when executed by the processor, cause the device to;
• send, to a terminal device, a set of hybrid automatic repeat request (HARQ) time sequence K1 values and time unit format information via one or more radio resource control (RRC) signalings, wherein a HARQ time sequence K1 value of the set of HARQ time sequence K1 values is a time relationship between a time unit of a physical downlink shared channel (PDSCH) and a time unit of a physical uplink control channel (PUCCH), or wherein a HARQ time sequence K1 value of the set of HARQ time sequence K1 values is a time relationship between a time unit of a PDSCH and a time unit of a physical uplink shared channel (PUSCH);
• and
• receive, from the terminal device, HARQ feedback information, wherein a quantity of HARQ feedback information bits is associated with the set of HARQ time sequence K1 values and the time unit format information.
