The invention discloses a dispatching method and dispatching equipment. The method comprises the following steps that: the signal to noise ratio (SNR) information of user equipment is calculated according to the serving and neighboring path loss (SNPL) information of a serving cell and a neighboring cell, the ratio UPH (UE power headroom) information of the maximum transmitting power available for the user equipment and the transmitting power required by an enhanced physical uplink channel (E-PUCH), and the maximum code rate information; and the user equipment is dispatched according to the SNR information. In the embodiment of the invention, the user equipment is dispatched according to the maximum SNR of the user equipment (UE). Compared with the conventional proportional fair (PF) dispatching algorithm and a maximum carrier to interference ratio (MAXC / I) dispatching algorithm, the method can improve the cell throughput and enhance the system performance.
Description
A scheduling method and device technical field The present invention relates to the field of communication technology, in particular to a scheduling method and equipment. Background technique In the prior art, the PF (proportional fair) scheduling algorithm includes: (1) The PF algorithm suitable for uplink enhancement is: Among them, it indicates the current channel condition and the average rate; in addition, since it indirectly reflects the channel condition of the UE (User Equipment, user equipment), it indicates the location of the UE and the interference to neighboring cells, so a compromised throughput with the fairness method as: in: In actual calculation, the time is converted into TTI (TransmissionTimeInterval, transmission time interval), and the average measurement parameter is updated every TTI. In the non-scheduling period or in the scheduling situation, if the user's cache is empty, the user does not participate in queuing and does not update the...
