| 摘要 |
The present invention relates to a data transmission method and a terminal. The data transmission method includes: detecting, by a first user terminal, PDCCH of second user terminals beyond a cell of the first user terminal, and acquiring modulation and coding scheme information from the PDCCH; estimating interference between the first user terminal and the second user terminals according to the modulation and coding scheme information; selecting a second user terminal having a minimum interference on the first user terminal according to the interference; and multiplexing, by the first user terminal, an uplink time-frequency resource of the second user terminal having the minimum interference to perform D2D data transmission. |
