PROCÉDÉ DE TRANSMISSION D'INFORMATIONS DE COMMANDE, DISPOSITIF TERMINAL ET DISPOSITIF DE RÉSEAU

摘要

This application provides a control information transmission method, a terminal device, and a network device. The method includes: determining, by a terminal device, a bit length of downlink control information DCI based on a location of a target first time unit in a second time unit, where the DCI includes time domain resource location information, the time domain resource location information is used to indicate at least one of time domain length information of a third time unit and time domain start location information for data transmission scheduled based on the DCI, the DCI is carried in the target first time unit, and a time domain length of the third time unit is less than or equal to a time domain length of the second time unit; and receiving, by the terminal device, the DCI from a network device. The control information transmission method in the embodiments of this application helps to reduce bit redundancy of the downlink control information DCI, prevents the terminal device from performing blind detection on downlink control information of different bit lengths, and reduces complexity of a receiver.
