US 11,082,963 B2 · Method, terminal device and network device for transmitting uplink control information

Abstract

Embodiments of the present disclosure disclose a method, a terminal device, and a network device for transmitting uplink control information, where the method includes: determining, by the terminal device, a second time domain resource set from a pre-configured first time domain resource set, where each time unit in the second time domain resource set is a candidate time domain unit for transmitting downlink data, wherein the first time domain resource set is determined according to an Acknowledgement (ACK)/Negative Acknowledgement (NACK) feedback timing sequence set of the downlink data; and transmitting, by the terminal device, in a target time unit, ACK/NACK feedback information corresponding to each time unit in the second time domain resource set to the network device. The method, terminal device and network device of the embodiments of the present disclosure are beneficial to reduce ACK/NACK feedback overhead.

A method for transmitting uplink control information, comprising:

determining, by a terminal device, a second time domain resource set from a pre-configured first time domain resource set according to a pre-configured downlink scheduling timing sequence set, wherein a value of each element in the downlink scheduling timing sequence set represents a time interval between downlink control information, DCI, and a corresponding physical downlink shared channel, PDSCH, wherein each time unit in the second time domain resource set is a time unit for transmitting downlink data, wherein the first time domain resource set is determined according to a target time unit and a pre-configured Acknowledgement (ACK)/Negative Acknowledgement (NACK) feedback timing sequence set of the downlink data;
and
transmitting, by the terminal device, in the target time unit, ACK/NACK feedback information corresponding to each time unit in the second time domain resource set to a network device.

A terminal device, wherein the terminal device comprising:

an input interface, an output interface, a processor, and a memory;
wherein
the processor, configured to determine a second time domain resource set from a pre-configured first time domain resource set according to a pre-configured downlink scheduling timing sequence set, wherein a value of each element in the downlink scheduling timing sequence set represents a time interval between downlink control information, DCI, and a corresponding physical downlink shared channel, PDSCH, wherein each time unit in the second time domain resource set is a time unit for transmitting downlink data, wherein, the first time domain resource set is determined according to a target time unit and a pre-configured Acknowledgement (ACK)/Negative Acknowledgement (NACK) feedback timing sequence set of the downlink data;
and
the output interface, configured to transmit, in the target time unit, ACK/NACK feedback information corresponding to each time unit in the second time domain resource set to a network device.

2 more elements

A network device, wherein the network device comprising:

an input interface, an output interface, a processor, and a memory;
wherein
the processor, configured to receive, in a target time unit, feedback information corresponding to each time unit in a second time domain resource set transmitted by a terminal device, wherein, the second time domain resource set is determined from a pre-configured first time domain resource set according to a pre-configured downlink scheduling timing sequence set, wherein a value of each element in the downlink scheduling timing sequence set represents a time interval between downlink control information, DCI, and a corresponding physical downlink shared channel, PDSCH, each time unit in the second time domain resource set is a time unit for transmitting downlink data, and the first time domain resource set is determined according to the target time unit and a pre-configured Acknowledgement (ACK)/Negative Acknowledgement (NACK) feedback timing sequence set of the downlink data.
