Patent ID: 10880036

Abstract:
Disclosed are a method for transmitting data, a terminal device and a network device. The method comprises: a terminal device determining an MCS level used to transmit a current target transmission block; the terminal device, according to the MCS level and a TBS mapping relationship when a pre-set first resource parameter is met, determining a first TBS corresponding to the MCS level, wherein the TBS mapping relationship comprises a mapping relationship between the MCS level and the TBS; the terminal device, according to a second resource parameter used to transmit the target transmission block and the first TBS, determining a second TBS; and the terminal device, according to the second TBS, sending the target transmission block to a network device, or receiving the target transmission block sent according to the second TBS of the network device. In this way, the terminal device can effectively obtain TBS information in the case that a value range of the resource parameter used to transmit data is relatively large.
