A data indicating method, comprising: receiving (2a02), by a terminal, a downlink control signaling from a network side device, wherein the downlink control signaling comprises a first information domain and a second information domain, the first information domain is configured to indicate whether a transport block scheduled by the downlink control signaling is a new transport block, and the second information domain is configured to indicate a coding block group scheduled by the downlink control signaling; and determining (2a03), by the terminal, a number of coding block groups comprised in the new transport block according to the first information domain and the second information domain; wherein the determining (2a03), by the terminal, the number of the coding block groups comprised in the new transport block according to the first information domain and the second information domain, comprises: determining (2b03), by the terminal, that the transport block scheduled by the downlink control signaling is a new transport block according to the first information domain; determining (2b04), by the terminal, that values of first K bits in the second information domain are all a preset value, wherein K is a positive integer; and determining (2b05), by the terminal, the new transport block, wherein the number of the coding block groups comprised in the new transport block is K. receiving (2a02), by a terminal, a downlink control signaling from a network side device, wherein the downlink control signaling comprises a first information domain and a second information domain, the first information domain is configured to indicate whether a transport block scheduled by the downlink control signaling is a new transport block, and the second information domain is configured to indicate a coding block group scheduled by the downlink control signaling; and determining (2a03), by the terminal, a number of coding block groups comprised in the new transport block according to the first information domain and the second information domain; wherein the determining (2a03), by the terminal, the number of the coding block groups comprised in the new transport block according to the first information domain and the second information domain, comprises: determining (2b03), by the terminal, that the transport block scheduled by the downlink control signaling is a new transport block according to the first information domain; determining (2b04), by the terminal, that values of first K bits in the second information domain are all a preset value, wherein K is a positive integer; and determining (2b05), by the terminal, the new transport block, wherein the number of the coding block groups comprised in the new transport block is K. determining (2b03), by the terminal, that the transport block scheduled by the downlink control signaling is a new transport block according to the first information domain; determining (2b04), by the terminal, that values of first K bits in the second information domain are all a preset value, wherein K is a positive integer; and determining (2b05), by the terminal, the new transport block, wherein the number of the coding block groups comprised in the new transport block is K.
