Abstract
Disclosed are a data transmission method and device. The method comprises: a sending end sending at least one synchronization signal (SI), with the SI carrying a first identifier; and at a time-frequency location of system information corresponding to the SI, sending the system information, the system information carrying information for indicating a second identifier, and identification information about the sending end comprising the first identifier and the second identifier. According to a mapping relationship between an SI and a first identifier, a receiving end can obtain the first identifier after detecting the SI; and by means of carrying information for indicating a second identifier in system information, the receiving end can obtain the second identifier after detecting the system information, so that the receiving end can obtain all the identification information about the sending end according to the first identifier and the second identifier.
