Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly Chu, it is fully described by.

See Fig. 1, it illustrates the distribution method flow process of the data a kind of to be dispatched that the embodiment of the present invention provides, The method can apply to the data to be dispatched of terminal are distributed the device respectively becoming sub-carrier being polymerized to this terminal In, the method may include that

S101: when current assignment period arrives, obtain the data to be dispatched of terminal；

It should be noted that the cycle of distribution can manually be arranged, implementing can be by an intervalometer It is managed.If the cycle setting BSR distribution is 1s, that is 1s carries out being retouched in a present embodiment The assigning process of the data to be dispatched stated.Current time reaches the assignment period of BSR, then proceed by and treat The distribution of scheduling data.

Exemplarily, the data to be dispatched obtaining terminal specifically may include that

Receive the buffer status report (BSR, Buffer State Report) that terminal sends；

Resolve BSR and obtain the data to be dispatched in terminal buffers district.

It should be noted that this BSR both can be descending BSR can also be up BSR, therefore, The data to be dispatched of terminal both can be the data that terminal needs to send in up buffer area, it is also possible to is eventually End needs the data received in down buffer storage district.Thus the present embodiment can realize the up and descending of terminal Data become at each distributes on sub-carrier, such that it is able to achieve terminal data on each one-tenth sub-carrier simultaneously The effect received and simultaneously send.

S102: obtain bandwidth information and the channel quality information of each one-tenth sub-carrier of terminal polymerization；Wherein, eventually The composition total number subcarriers of end polymerization is at least one；

S103: according to terminal polymerization each become the bandwidth information of sub-carrier and channel quality information and default What the data to be dispatched of terminal were distributed to terminal polymerization by allocation rule respectively becomes sub-carrier；

Exemplarily, step S103 specifically may include that the i-th composition being obtained terminal polymerization by formula (1) Data BSR_CC to be dispatched of the terminal that carrier wave is assigned to_i:

$\mathrm{BSR}\_{\mathrm{CC}}_i=\mathrm{ceil}\left(\frac{\mathrm{BSR}\_\mathrm{UE}\×W\_\mathrm{BW}\_{\mathrm{CC}}_i\×W\_\mathrm{CQ}\_{\mathrm{CC}}_i}{\underset{a=1}{\overset{N}{\mathrm{\Σ}}}(W\_\mathrm{BW}\_{\mathrm{CC}}_a\×W\_\mathrm{CQ}\_{\mathrm{CC}}_a)}\right)---\left(1\right)$

Wherein, ceil () represents the smallest positive integral being more than or equal to；BSR_UE is the number to be dispatched of terminal According to size；W_BW_CC_iI-th for terminal polymerization becomes the bandwidth of sub-carrier；W_CQ_CC_iFor terminal The i-th of polymerization becomes the weight corresponding to channel quality information of sub-carrier；W_BW_CC_aIt is polymerized for terminal The a one-tenth sub-carrier bandwidth；W_CQ_CC_aChannel matter for a one-tenth sub-carrier of terminal polymerization Weight corresponding to amount information；N is the composition total number subcarriers of terminal polymerization.

Preferably, the i-th of terminal polymerization becomes the weight corresponding to channel quality information of sub-carrier, permissible The i-th being polymerized by terminal becomes the channel quality of sub-carrier to indicate (CQI, Channel Quality Indicator) Or modulation and coding strategy (MCS, Modulation and Coding Scheme) or spectrum efficiency (SE, Spectral Efficiency) it is indicated；In an embodiment of the present invention, using become the CQI of sub-carrier as Weight corresponding to channel quality information illustrates, it is possible to understand that, become other channel qualities of sub-carrier Forms of information representations can also be applied to the technical scheme of the embodiment of the present invention, does not repeats them here.

Need illustrate, when terminal polymerization any one become sub-carrier be not scheduled or according to The fail-ure criterion strategy preset judges when the channel quality information of any one one-tenth sub-carrier of terminal polymerization lost efficacy, The weight corresponding to channel quality information of all the components carrier wave of terminal polymerization is the most equal；In the present embodiment, Now the weight corresponding to the channel quality information of all the components carrier wave all represents with 1.

And in the present embodiment, the fail-ure criterion strategy preset can be the channel quality letter of one one-tenth sub-carrier in office The most again dispatch in ceasing the prefixed time interval after being scheduling, then judge the channel matter of this one-tenth sub-carrier Amount information lost efficacy；In the present embodiment, the time interval preset can be 80ms.

Following two concrete condition is described in detail by the technical scheme next combining above-described embodiment:
