As shown in Figure 1, be the embodiments of the invention flow chart, below in conjunction with the flow chart of embodiment the present invention launched to elaborate.

S101: classify to terminal in the base station.

In the present embodiment, be example with the cellular mobile communication, support the base station of MIMO multi-antenna technology to send downstream signal to terminal, and the upward signal of receiving terminal transmission.The attribute of each terminal under its service area is understood by the information that terminal sends in the base station.In real-time system, may there be polytype terminal, for example, whether support the characteristics of MIMO technology to be divided three classes according to terminal, comprising: the category-A terminal, wherein the category-A terminal is not supported the MIMO technology, with single current mode downlink data receiving; The category-B terminal, wherein the category-B terminal is supported the MIMO technology, with single current mode downlink data receiving; The C Terminal Type, wherein the C Terminal Type is supported the MIMO technology, with double-current mode downlink data receiving.The base station will be determined the method for salary distribution of its Midamble sign indicating number according to the type of terminal after the attribute of understanding particular terminal.

In addition, terminal with the process of base station communication in, may make adjustment as the case may be, for example, the category-B terminal can switch to the C Terminal Type, with double-current mode downlink data receiving; The C Terminal Type also can switch to the category-B terminal, with single current mode downlink data receiving.

S102: the method for salary distribution of Midamble sign indicating number is selected according to the classification of terminal in the base station, and notifies terminal.

In the standard of existing TDD system, allocative decision to the Midamble sign indicating number is the situation that a data flow sends at the data of terminal reception only, utilize technical scheme of the present invention, can realize the terminal of supporting the MIMO technology is realized the distribution of Midamble sign indicating number simply, efficiently.

In the present embodiment, the method for salary distribution of multiple Midamble sign indicating number can be selected in the base station to various terminals.The Midamble sign indicating number method of salary distribution comprises the default allocation mode, in the default allocation mode, different Midamble sign indicating numbers is produced after cyclic shift by same basic Midamble sign indicating number, and the terminal of a certain class is distributed to the channelization code resource of Midamble sign indicating number and binding by the default allocation mode in the binding that each Midamble sign indicating number and channelization code resource are given tacit consent to, base station.

More specifically, the Midamble sign indicating number sends to terminal in the centre of each conventional time slot, and length is 144 chips.The Midamble sign indicating number that the different user of the identical time slot of same cells uses is produced after cyclic shift by same basic Midamble sign indicating number.The transmitting power of various piece must be consistent in time slot, namely the transmitting power of Midamble part with the transmitting power of data division and consistent, do not carry out spread spectrum and scrambling.The binding that each Midamble sign indicating number displacement and channelization code resource are given tacit consent to.For example when each displacement was 16 chips, a basic Midamble sign indicating number can derive 8 displacements of Midamble sign indicating number, i.e. 8 different Midamble sign indicating numbers altogether.So the displacement of each Midamble sign indicating number corresponding 2 spreading factor SF be 16 code channel, the channelization code resource of certain Midamble sign indicating number and binding is distributed to the terminal of a certain class in the base station.

In addition, the method of salary distribution of Midamble sign indicating number also comprises the public method of salary distribution, in the public method of salary distribution, different Midamble sign indicating numbers is produced after cyclic shift by same basic Midamble sign indicating number, each user uses in the displacement of all Midamble sign indicating numbers one jointly under the described base station, and specific channelization code resource is being bound in the displacement of any one Midamble sign indicating number all correspondence;
