1. a kind of data transmission method, for the data transfer between the Base Band Unit and remote radio unit (RRU) of distributed base station,It is characterised in that it includes the data transmitted between the Base Band Unit and remote radio unit (RRU) are frequency domain data, in the distal endTime-domain and frequency-domain conversion is carried out to data in radio frequency unit;

  • Before being additionally included in frequency domain data, the frequency domain data is carried outCompression;

    Wherein, the frequency domain data is transferred to remote radio unit (RRU) and includes by Base Band Unit:

    At in Base Band Unit by base bandFrequency domain data after reason is transferred to remote radio unit (RRU) by IR interfaces;

    Remote radio unit (RRU) is changed to the frequency domain dataObtain time domain data.
