A kind of GSM system and LTE system spectrum sharing method, including: the distribution of this cell and adjacent cell interference to the district's GSM system frequency, avoid the fixed channel cell LTE system; LTE distribution system PDSCH and PUSCH instructions to the user and the small frequency resource area and interference the area of the adjacent cell GSM system frequency in a frequency resource for the LTE system; PCFICH and PHICH, the distribution of this cell and adjacent cell interference to the district's GSM system frequency, avoid the LTE system more than two channels, or GSM system frequency LTE system with proper distribution of CellID to avoid this cell and adjacent cell interference to the district's. The invention also provides a shared spectrum system. By using the method and the system of the invention, the GSM system can be smoothly transferred to the LTE system when the efficiency of spectrum utilization is improved.
