DATA TRANSMISSION METHOD AND DEVICE

摘要

Provided are a data transmission method and device. The method includes: according to a preconfigured second table, selecting a TBS value, the second table being used for describing the correlation among a TBS value, the number of RBs, and a TBS index, the number of RBs corresponding to the selected TBS value being smaller than or equal to a specific value, the modulation mode corresponding to a TBS index which corresponds to the selected TBS value being QPSK, and the selected TBS value being capable of satisfying the rate requirement required during the transmission time interval TTI bundling transmission; and according to the selected TBS value, transmitting data borne by a PUSCH using a bundled TTI. The embodiments of the present invention can improve the coverage of a PUSCH at an intermediate data rate.
