  • the scheduling algorithm of the user equipment plays a key role in obtaining the resources that satisfy the service requirements and ensuring the overall system throughput in the cell.
  • the main problem solved by the scheduling algorithm of the MAC layer is to decide which users to allocate to at what time.
  • kind of wireless resources to communicate for example, the Long Term Evolution (LTE) standard system developed by the 3rd Generation Partnership Project (3GPP).
  • the throughput generally refers to the amount of data transmitted per unit time.
  • the fairness refers to whether all user equipments (User Equipments, UEs) of the cell have obtained certain service opportunities.
  • the purpose of the MAC layer scheduling algorithm is to use the time-varying characteristics of the UE to obtain multi-user diversity gain, improve the overall throughput of the system, and ensure the fairness of the cell users. Therefore, a good scheduling algorithm should take into account both cell throughput and user fairness. .
  • the current MAC layer scheduling algorithms mainly have the following three types:
  • Max C/I Maximum carrier-to-interference ratio
  • the Max C/I scheduling algorithm always assigns resource blocks (RBs) to the C/I maximum, that is, the UE with the best channel conditions.
  • RBs resource blocks
  • the biggest advantage of this algorithm is that it can obtain the maximum cell data throughput and resources. Utilization, but unfavorable is that the fairness of resource allocation is not considered at all, resulting in UEs with poor channel conditions being blocked for a long time. For example, a UE at the cell edge may not be as good as a UE at the cell center because the C/I is not as good as the UE at the cell center. There is no chance of being assigned an RB at all;
  • the core of the RR scheduling algorithm is to assume that all UEs have the same scheduling priority, so as to ensure that resources are allocated to all UEs in the system with equal opportunities, so that the UEs occupy radio resources for communication in a certain order. From the perspective of resource occupation, the RR scheduling algorithm is the most fair, but since the channel conditions of the user are not considered, the reliability of the transmission is not high, resulting in extremely low cell throughput and resource utilization.
  • the PF scheduling algorithm allocates a priority to each UE in the cell, and at each scheduling moment, the UE with the highest priority is preferentially scheduled.
  • the PF scheduling algorithm not only considers the channel time-varying characteristics of the UE, but also ensures the balance between multi-user diversity and fairness of the system, so that the throughput of the system and the fairness of resource allocation can be considered.
  • the above three scheduling algorithms only distinguish the scheduling priority of the UE according to the quality of the wireless channel, and do not consider the actual demand of the UE for the resource.
  • the actual demand of the UE for resources is not directly related to the quality of the wireless channel.
  • the actual demand of the UE for the resource may be reflected from the historical throughput of the UE in the cell, and the historical throughput of the UE in the cell is larger, which indicates that the actual demand of the UE for the resource is greater to some extent. Therefore, an algorithm for measuring the UE scheduling priority according to the historical throughput of the UE in the cell has emerged. If the historical throughput of the UE is higher, the scheduling priority of the UE is also higher.
  • the above algorithm for measuring the UE scheduling priority according to the UE's historical throughput in the cell is used.
  • the target base station cannot know that the UE is in the source.
  • the base station corresponds to the historical throughput in the cell, and the historical throughput of the UE in the corresponding cell of the target base station can be referred to. Therefore, when the UE switches to the target base station, the target base station needs to count the historical throughput of the UE from zero, and cannot be based on the UE.
  • the existing historical throughput is used to calculate the scheduling priority of the UE, so that the scheduling of the target base station to the UE may not meet the requirements of the UE for resources, resulting in a decrease in scheduling performance.
