Before the dispatching method to the embodiment of the present invention is described in detail, the adjustment mode of MCS is said first
It is bright：LTE supports link adaptation techniques to carry out the adjustment mode of MCS, includes mainly following several：For outer shroud, usually it is arranged
The benchmark that fixed initial target BLER is adjusted as MCS, and based on the initial adjustment amounts of fixed MCS and MCS promotions/reduction step
The long adjustment for carrying out MCS；Wherein, the initial adjustment amounts of MCS are preconfigured, it can be understood as, the adjustment of MCS is initial from MCS
Adjustment amount is adjusted as starting point, and during the adjustment, according to the MCS step-length is promoted/reduced as adjustment every time
Amplitude.It is described for data service, it is 10% maximumlly to give tacit consent to as throughput of system that initial target BLER, which is usually arranged,
Value, for speech business (VoLTE, Voice over LTE) speech business based on IMS, to reduce packet loss to voice quality
It influences, usual initial target BLER need to be set as 10%；The conservative initial adjustment amount of generally use (for example MCS lowers 3~4
Rank), much smaller than the step-length that MCS is reduced, (for example terminal feeding back ACK, MCS then promote 1% to the step-length that MCS is promoted；Terminal is fed back
9%) NACK, MCS are then reduced；For inner ring, the mapping of MCS is carried out after being usually filtered to the CQI of reporting of user, it is general new
CQI weight accounting about 20% or so.Wherein, the MCS of selection is associated with CQI；Specifically, carrying out reflecting for MCS according to CQI
