For supporting that little bandwidth terminals is at LTE (LongTermEvolution, Long Term Evolution) work in system, existing existing program is considered in LTE system band of operation, mark off separately the transmission of one or more frequency band for little bandwidth terminals (or claiming narrowband terminal) business, for little bandwidth terminals, the Resourse Distribute of up-downgoing respectively as shown in Figure 1 and Figure 2.Control area due to traditional LTE system has occupied front several OFDM (OrthogonalFrequencyDivisionMultiplexing, OFDM) symbol, so the primary sign of little bandwidth system is behind the control area of LTE.
The system works bandwidth defined in existing protocol has following several:
Channel width (MHz) 1.4 3 5 10 15 20
Transmission bandwidth configuration (PRB number) 6 15 25 50 75 100
Realizing in process of the present invention, inventor finds prior art, and at least there are the following problems:
In order to save cost, little bandwidth terminals generally can adopt the filtering device of bandwidth relative narrower (comparing LTE system bandwidth of operation), the terminal of such as 5MHz bandwidth can adopt the filter of 5MHz, but because radio-frequency filter characteristic is not desirable linear characteristic in edge, when the medium and small bandwidth terminals of LTE system and conventional terminal (or claiming wide-band terminal) exist simultaneously, the interference problem between little bandwidth terminals and the signal of conventional terminal may be caused, make a concrete analysis of as follows: (below with system works bandwidth for 20MHz, the bandwidth of operation of little bandwidth terminal filter part is 5MHz is example, the bandwidth of operation of conventional terminal filtering device at least comprises 20MHz)
In downlink business process; little bandwidth terminals carries out filtering to system broad signal (20MHz); leaching respective bandwidth (5MHz) interior signal does check processing; based on existing LTE system bandwidth of operation configuration; little bandwidth terminals is actual takies 25 PRB (PhysicalResourceBlock; Physical Resource Block); the bandwidth of its actual signal is 25*180KHz=4.5MHz; and the bandwidth of operation of little bandwidth terminal filter is 5MHz, remaining 0.5MHz is divided equally in both sides as guard band.If when system carries out downlink data transmission, the signal of the working band of the conventional terminal in the working band both sides of little bandwidth terminals will enter the roll-off region (nonlinear area) of the filter of little bandwidth terminals, be illustrated in fig. 3 shown below, filtered device changes by the amplitude-phase of this part signal, therefore cannot ensure to keep orthogonality with little bandwidth signal, therefore can cause the interference to little bandwidth signal.
