Embodiments of the invention are applied to LTE or LTE-A communication systems; shown in reference picture 2; each channel parallel carries out signal transmission; it is transmitted in the transmission bandwidth of signal in the channel; due to interference can be produced between signal; so fractional bandwidth beyond transmission bandwidth is reserved as protection interval, interfering with each other between the signal to weaken different channels.If these channels return same operator to manage, operator can solve between the signal of different channels the problem of interfering with each other, then protection interval need not be reserved, so as to cause the waste of resource.The present invention adds transmission bandwidth, relatively reduces protection interval, so as to improve the utilization rate of channel width resource by the way of extension transmission bandwidth.

Embodiments of the invention provide a kind of method for distributing bandwidth, shown in reference picture 3, comprise the following steps：

The extension transmission bandwidth information of base station configuration is obtained, for example, referring to the transmission bandwidth shown in Fig. 4, provided in the protocol after the corresponding extension of different size of channel（Or, it is necessary to the transmission bandwidth of extension）, base station extended accordingly according to the size of channel after transmission bandwidth（Need the transmission bandwidth of extension）.As a width of 3MHz of the band of channel, then available transmission bandwidth is 16 Physical Resource Block after being expanded（Physical Resource Block, abbreviation PRB) (transmission bandwidth of extension is 1 Physical Resource Block）, 1 PRB size is 180KHz.Certainly one or several in the transmission bandwidth, the transmission bandwidth of lower sideband extension that upper side band extension is indicated, lower sideband extends instruction, upper side band extends can also be configured.

Or, obtain the extension transmission bandwidth information that base station is calculated, for example, when channel width is 3 MHz, it is 16 (3MHz ÷ 180KHz=1 6 ... 120KHz) that then channel width, which can bear most PRB quantity, you can transmission bandwidth maximum is 16 PRB.Transmission bandwidth before extension is 15 PRB, then the transmission bandwidth extended is 1 PRB.One or several in the transmission bandwidth, the transmission bandwidth of lower sideband extension that upper side band extension is indicated, lower sideband extends instruction, upper side band extends can certainly be additionally configured according to result of calculation.

Wherein, because transmission bandwidth is a part for channel width, corresponding transmission bandwidth, which needs to meet, under one channel width is less than or equal to the channel width, available transmission bandwidth after extending in transmission bandwidth information is extended not to be restricted no more than the channel width, but specific transmission belt width values.

Optionally, when the transmission bandwidth for extension being obtained in base station is 1 PRB, while base station is only extended to upstream bandwidth, then the extension transmission bandwidth information obtained can be：The transmission bandwidth that the transmission bandwidth of extension is 1 PRB and upper side band extension is indicated and upper side band extends is 1 PRB, or, the transmission bandwidth that upper side band extension is indicated and upper side band extends is 1 PRB, or, the transmission bandwidth of upper side band extension extension is 1 PRB.Extension transmission bandwidth information is configured according to channel concrete condition, and the concrete mode of other situations is just repeated no more. 102nd, base station is extended according to extension transmission bandwidth information to transmission bandwidth.Extension transmission bandwidth information according to step 101, the extension transmission bandwidth information can at most include 6 sub-informations（It is minimum to include 1）, it is respectively：Available transmission bandwidth, the transmission bandwidth of extension, upper side band extension instruction, lower sideband extension instruction, the transmission bandwidth of upper side band extension, the transmission bandwidth of lower sideband extension after extension.Base station is transmitted the extension of bandwidth according to this 6 sub-informations.

If only according to default rule, such as transmission bandwidth is extended according to order from low to high comprising available transmission bandwidth or the transmission bandwidth of extension after extension；Indicated if only being extended comprising upper side band（Lower sideband extension is indicated；), then by the upper side band of the transmission bandwidth（Lower sideband）All extensions；If the transmission bandwidth only extended comprising upper side band（The transmission bandwidth of lower sideband extension）, then by the upper side band of transmission bandwidth（Lower sideband）Extend corresponding transmission bandwidth.The extension transmission bandwidth information of other modes than above-mentioned several instruction all include more sub-informations, be in order to ensure extend transmission bandwidth information reliability, just repeat no more here.
