Description
Technical field
The present invention relates to communication technical field, particularly a kind of method, system and device that large transmission bandwidth is provided for the Long Term Evolution broadband system.
Background technology
In the Long Term Evolution wide-band mobile communication system, for example LTE-Advanced or IMT-Advanced system, need provide higher peak rate by bigger transmission bandwidth, satisfy user's demand, but the expansion of transmission bandwidth be limited by the frequency resource that operator has.Because the frequency resource that operator has is limited, therefore in order to satisfy the bandwidth demand of LTE-A system, need to pass through with the polymerization of a plurality of continuous or discrete LTE frequency range, then each frequency range maximum bandwidth is consistent with the bandwidth of current LTE system, i.e. 20MHz.In addition, because the LTE-A system also needs and the good backwards compatibility of existing Long Term Evolution LTE system's maintenance, guarantee that the LTE terminal also can insert smoothly, therefore each frequency range in the LTE-A system is all wanted compatible LTE terminal works, so its center frequency point need be located at current definition is on the channel grid (Channel Raster) at interval with 100kHz.
The basic skills of expansion transmission bandwidth is: keeping existing LTE system parameters, as subcarrier spacing, on the basis of invariable such as system bandwidth, a plurality of LTE frequency ranges are aggregated into the LTE-A frequency range, keep the new LTE-A system compatibility for the LTE terminal simultaneously.At present when having a plurality of available continuous LTE frequency range, the method that they is aggregated into a LTE-A frequency range has following several:
Method one
As shown in Figure 1, polymerization schematic diagram for art methods one, this method is carried out polymerization with a plurality of continuous LTE frequency ranges provides the LTE-A system bigger biography bandwidth, and as the continuous LTE frequency range of three 20MHz directly can being connected, the basic parameter of each frequency range all is consistent with existing LTE system.This method realizes comparatively simple, and can guarantee each LTE frequency range center all on the channel grid, thereby to the LTE terminal as seen, promptly the LTE terminal can be worked in each frequency range.But this method has all been reserved the frequency protection band of twice between each frequency range, and is comparatively serious to the waste of frequency resource.
Ten thousand methods two
As shown in Figure 2; polymerization schematic diagram for art methods two; this method directly couples together the effective bandwidth of 3 LTE frequency ranges; wherein the radio frequency bandwidth of each LTE frequency range is 20MHz; the effective transmission bandwidth of physical layer is 18.015MHz; and the frequency range both sides after polymerization respectively keep 2.9775MHz as boundary belt, and then the LTE-A system can use continuous aggregate bandwidth.Simultaneously, it is on the channel grid at interval that the center frequency point of middle 18.015MHz bandwidth is positioned at 100kHz, makes the LTE terminal can search the synchronizing signal of LTE system on the channel grid, thereby correct the access communicates.But the 18.015MHz frequency range of the left and right sides is not because center frequency point and channel grid line up, so the LTE terminal can't search this frequency range, cause these two frequency ranges for LTE do not have afterwards to compatibility.Though the physical resource that this method can keep the LTE-A system to use is continuous; but there are two frequency ranges invisible to the LTE terminal; influence backwards compatibility, and too much frequency protection band has been reserved in the frequency range both sides after the polymerization, had the problem of frequency resource waste.
Method three
As shown in Figure 3; polymerization schematic diagram for art methods three; this method directly couples together the effective bandwidth of 3 LTE frequency ranges; wherein the radio frequency bandwidth of each LTE frequency range is 20MHz; the effective transmission bandwidth of physical layer is 18.015MHz; and between two adjacent effective frequency ranges, insert the protection subcarrier (sub-carrier number of Cha Ruing is 19 as shown in FIG.) of some, make all frequency range centers all be positioned on the channel grid.The center frequency point that this method can make all frequency ranges is all on the channel grid, thereby to the LTE terminal as seen, and the boundary belt between each frequency range is less.Its shortcoming is: because the boundary belt between the frequency range is too small; at the signal of the LTE of a certain frequency range work terminal emission/reception other LTE terminals of successive bands are caused interference; frequency range both sides boundary belt after the polymerization is reserved too much in addition, has the problem of frequency resource waste.
