Embodiment Construction
[0058] The present invention will be further described below in conjunction with drawings and embodiments.
[0059] Such as figure 1 The shown uplink scheduling correction method based on the LTE system includes:
[0060] S1. Calculate the signal-to-interference-plus-noise ratio at time t1+k according to the power headroom at time t1+k and the interference and noise power values at time t1+k, and use it as a reference value. Specifically, during the power headroom reduction process on the terminal side, at time t1, the modulation and coding strategy MCS value of the scheduled uplink shared channel PUSCH and the preset reference threshold value MCS threshold When the difference is less than the preset value m, get the spectral efficiency SE at time t1+k t1+k , the number of schedulable data channel RBs at time t1+k And the power headroom PHR reported by the terminal side between t1 and t1+k time t1 ; where k≥0, and the time t1+k is the scheduling time closest to the tim...
