    • Provided is a data transmission method and device. The method includes: receiving IQ data from an uplink; according to the mapping of the IQ data in a Common Public Radio Interface (CPRI) basic frame, utilizing at least one storage unit to sequence the IQ data; combining a control word with the sequenced IQ data to form CPRI data, and transmitting the CPRI data. The solution utilizes at least one storage unit to sequence the IQ data, and extracts the sequenced data for a CPRI framing operation. This solution is simple in hardware processing and low in realization complexity. The change and upgrade of the transmission bandwidth of multiple modes (single mode or mixed mode) during system upgrade only occur on software layer without affecting the realization of hardware, thus having good flexibility.
    • 提供了一种数据传输方法和装置。 该方法包括:从上行链路接收IQ数据; 根据公共无线电接口(CPRI)基本帧中的IQ数据的映射,利用至少一个存储单元对IQ数据进行排序; 将控制字与排序的IQ数据组合以形成CPRI数据,并发送CPRI数据。 该解决方案利用至少一个存储单元对IQ数据进行排序,并提取CPRI成帧操作的排序数据。 该解决方案在硬件处理上很简单,实现复杂度低。 系统升级过程中多种模式(单模或混合模式)的传输带宽的变化和升级只发生在软件层,而不影响硬件的实现,具有良好的灵活性。
