Description
Technical field
The present invention relates to communication technical field, particularly relate to the method and apparatus that a kind of resource is distributed.
Background technology
M2M (Machine-To-Machine, machinery compartment) communication is as a kind of novel communication theory, its objective is that the communication technology with number of different types organically combines, as: machine is to machine communication, machine control communication, man-machine interaction communication, mobile interconnected communication, thus the development of promotion social production and life style.The business of estimating following Human To Human's communication may only account for 1/3rd of whole terminal market, and the communication of bigger quantity is machinery compartment (little bandwidth system) communication service.
Current mobile communications network designs at interpersonal communication, as determining etc. of: network capacity.Support little bandwidth system communication just need be optimized according to the characteristics of the little bandwidth system communication mechanism to mobile communication system if wish to utilize mobile communications network, in order to can communicate by letter unaffected traditional person to person or be subjected to and realize little bandwidth system communication better under the less situation about influencing.
The characteristic that present MTC (Machine Type Communications, machine type communication) communication may exist comprises one or more in the following characteristic: the MTC terminal has Hypomobility; The time that MTC terminal and network side carry out transfer of data is controlled, and namely the MTC terminal can only insert in the time period of network appointment; The transfer of data that MTC terminal and network side carry out is less demanding to real-time to transfer of data, namely has the time tolerance; MTC terminal energy constraint requires lower power consumption; Only carry out the information transmission of small data quantity between MTC terminal and the network side; The MTC terminal can be that unit manages with the group, etc.
For supporting little bandwidth terminals at LTE (Long Term Evolution, Long Term Evolution) works in the system, existing existing program is considered to mark off separately one or more frequency bands and is used for the professional transmission of little bandwidth terminals (or claiming narrowband terminal) in LTE system works bandwidth range, at little bandwidth terminals, the resource of up-downgoing is distributed respectively as shown in Figure 1 and Figure 2.Because several OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbol before the control area of traditional LTE system has taken is so the primary sign of little bandwidth system is behind the control area of LTE.
The system works bandwidth that defines in the 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 |
In realizing process of the present invention, the inventor finds prior art, and there are the following problems at least:
In order to save cost, little bandwidth terminals generally can adopt the filtering device of bandwidth relative narrower (comparing LTE system works bandwidth), can adopt the filter of 5MHz such as the terminal of 5MHz bandwidth, but because the 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) when existing simultaneously, may cause the interference between signals problem of little bandwidth terminals and conventional terminal, make a concrete analysis of as follows: (following is 20MHz with the system works bandwidth, the bandwidth of operation of little bandwidth terminals filtering device is that 5MHz is example, and the bandwidth of operation of conventional terminal filtering device comprises 20MHz at least)
In the downlink business process; little bandwidth terminals is carried out filtering to system's broadband signal (20MHz); the interior signal of leaching respective bandwidth (5MHz) is done to detect and is handled; based on existing LTE system works band width configuration; actual 25 PRB (Physical Resource Block, Physical Resource Block) that take of little bandwidth terminals, the bandwidth of its actual signal is 25*180KHz=4.5MHz; and the bandwidth of operation of little bandwidth terminals filter is 5MHz, and remaining 0.5MHz is divided equally in both sides as the protection frequency band.When if system carries out the downlink data transmission, will enter the zone of roll-offing (nonlinear area) of the filter of little bandwidth terminals at the signal of the working band of the conventional terminal of the working band both sides of little bandwidth terminals, be illustrated in fig. 3 shown below, the amplitude-phase of this part signal changes filtered device, therefore can't guarantee to keep orthogonality with little bandwidth signal, therefore can cause the interference to little bandwidth signal.
In the uplink service process, the 5MHz signal of little bandwidth terminals emission enters base station receiver with the signal of conventional terminal emission.Because the characteristic of little bandwidth terminals filter is not desirable linear characteristic in edge, the signal at its edge is through behind the zone of roll-offing of filter when carrying out the signal emission, as shown in Figure 4, amplitude-phase all can change by filtered device, meeting causes interference to the signal of the working band of the conventional terminal of the working band both sides of little bandwidth terminals, be illustrated in fig. 4 shown below, be respectively the upward signal emission process of little bandwidth terminals and ordinary terminal.Particularly, at the working band edge of the little bandwidth terminals PUCCH that transmitting power is stronger probably (Physical Uplink Control Channel, physical uplink control channel) signal, therefore the interference to conventional terminal just more can not be ignored.
