Method for transmitting feedback information, terminal device and network device

Abstract

The embodiment of the invention provides a method for transmitting feedback information, terminal equipment and network equipment, and the method comprises the steps: determining a target shift digitof cyclic shift according to a target determination mode in multiple determination modes; Circularly shifting the base sequence by the target shift number to obtain a feedback information sequence carrying feedback information; Sending the feedback information sequence to network equipment; Wherein the various determination modes comprise the steps of determining the target shift digits by adopting a mode of randomizing the shift digits between different time units, determining the target shift digits by adopting a mode of jumping the shift digits between different time units, and determiningthe target shift digits according to a preset corresponding relation between feedback information and the shift digits. According to the method provided by the embodiment of the invention, the terminal equipment can flexibly determine the shift digits of the cyclic shift from multiple determination modes, and the realization complexity of the terminal equipment is reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically relates to a method for transmitting feedback information, a terminal device and a network device. Background technique [0002] With the development of wireless communication technology, the future communication system needs to adapt to more diverse scenarios and business requirements. In order to meet different business requirements and different application scenarios, the New Radio (NR) system introduces different lengths of physical uplink control channel (Physical Uplink Control Channel, PUCCH), and at the same time, according to the size of the uplink control information (Uplink Control Information, UCI) payload (Payload) carried by the PUCCH, it is further divided into the PUCCH with the UCI Payload carried less than or equal to 2 bits and the PUCCH carried The UCI Payload is greater than the 2-bit PUCCH. For a PUCCH with a UCI Payload that is less th...
