Provided are a data transmission method and apparatus. A terminal side transmission method comprises: sending repeatedly, by a terminal, data packets to a base station through an uplink random access channel so that the base station correctly receives the data packets in an energy accumulation manner. Correspondingly, a base station side transmission method comprises: receiving, by a base station, data packets repeatedly sent by a terminal through an uplink random access channel; and merging, by the base station, all of the received data packets and parsing information about an obtained message part; wherein a prefix part of the data packets is repeatedly sent N times, and a message part of the data packets is repeatedly sent M times, where 1≤N, and 1<M. In the solution of the embodiments of the present invention, a terminal repeatedly sends data packets to a base station, and the base station performs merging processing on all of the data packets repeatedly sent by the terminal and then demodulates out information to be sent by the terminal from the merged data packets. The base station may realize super-range coverage in such an energy accumulation manner without increasing the transmission power. |
