Communication scheduling

In communication services, spectrum resources and power resources are limited, but the number of users and traffic in the cell are different. The system cannot only consider some users. It must allocate resources reasonably so that users in the system can Normal good communication. This allocation method or strategy is a scheduling algorithm or a scheduling technique.

Maximum load-to-interference ratio and polling scheduling are two scheduling extremes based on maximization of throughput and fairness. The actual scheduling algorithms are somewhere in between, and the most commonly used is proportional fair scheduling. Proportional fair scheduling considers not only the fairness among users (so that all users are served), but also system throughput optimization (to maximize spectrum efficiency and solve costs).

In summary, the scheduler uses appropriate methods (such as PR (Premium Rate Preannouncement, prompting the user's tariff information before the call is connected), MAX C / I, and PF scheduling at the appropriate time (a specific transmission interval). Algorithm) allocate appropriate resources (such as PRB (Physical Resource Block), HARQ (Hybrid Automatic Repeat Request), and PDCCH CCE (Control Channel) to appropriate users (some users in the system) Element (control channel unit), power, etc.) to enable users in the system to communicate normally and well, is the scheduling technology in communication services.
