FIELD: communication.
SUBSTANCE: invention relates to the field of communication, specifically to a method of transmission of feedback information. The technical result of the proposed technical solution is achieved by the proposed solution including a terminal device and a network device, wherein the feedback mode used for transmitting feedback information can be dynamically adjusted using said terminal device and network device, wherein the terminal device determines the target feedback mode used for transmission of feedback information, wherein the feedback information is feedback information for a transport block (TB) transmitted by the network device and received by the terminal device; and the terminal apparatus uses the target feedback mode to transmit feedback information, wherein the target feedback mode includes feedback via ACK/NACK with a size of 1 bit for TB or feedback via bitmap for TB.
EFFECT: improved utilization rate of transmission resources for the feedback channel.
