The user of simultaneously traditional gsm system is fewer and feweri, provides the LTE system of more high data rate User gets more and more, and this makes the frequency spectrum of gsm system idle in a large number, and the frequency spectrum of LTE system is not enough. In order to meet the demand in market, operator is fundamentally changing them and is utilizing the mode of existing frequency spectrum, frequently Spectrum reformation (spectrum refarming) is one of which.
Frequency spectrum reform be solve business demand exponential increase and frequency spectrum resource limited between the one side of contradiction Formula, utilizes frequency spectrum to reform and can promote utilization ratio and the flexibility of frequency spectrum, by the idle frequency of gsm system Spectrum resource lends the LTE system being provided that more high data rate, including following several implementation:
1) the descending idle frequency spectrum of gsm system is lent LTE frequency division multiplexing (FDD, Frequency Division Duplexing) descending, the up idle frequency spectrum of gsm system is lent LTE FDD up；
2) the descending idle frequency spectrum of gsm system is lent time-division LTE (TD-LTE, Time Division Long Term Evolution)；
3) the up idle frequency spectrum of gsm system is lent TD-LTE；
4) the up-downgoing idle frequency spectrum of gsm system is lent TD-LTE.
