A user terminal group scheduling method and device

Abstract

Embodiments of the present invention provide a user terminal group scheduling method and device. The method includes: receiving measurement report information reported by the user terminal. The measurement report information includes the identification of the user terminal, the measurement time, and the primary serving cell and neighbors of the user terminal. Frequency point information and reference signal received power information corresponding to the districts respectively; according to the measurement report information, calculate the signal-to-interference ratio of the user terminal according to the first preset rule; use the user terminal with the signal-to-interference ratio greater than the preset threshold as the cell center user group, and The user terminals whose signal-to-dryness ratio is less than the preset threshold are used as the cell edge user group; according to the second preset rule, the first network resource scheduling algorithm and the second network resource scheduling algorithm are used for the user terminals in the cell center user group and the cell edge user group respectively. The scheduling algorithm schedules network resources. The device is used to perform the above method. The embodiment of the present invention reduces the time for network scheduling, and further improves the speed of network resource scheduling.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless networks, and in particular to a user terminal group scheduling method and device. Background technique [0002] With the development of science and technology, the LTE network is also constantly developing and improving, which greatly improves the service quality of the mobile communication network. With the development of the LTE network and the continuous improvement of various services, more and more users use the LTE network. How to allocate network resources for each user, that is, how to schedule network resources, has become a key technology. [0003] In the prior art, the following four scheduling strategies are mainly included: Max C / I, RR (Round Robin), PF (Proportional Fair) and EPF (Enhanced Proportional Fair). The selection of uplink and downlink scheduling strategies is determined by parameters respectively, among which Max C / I, RR, and PF are basic schedulin...

AI Technical Summary

Problems solved by technology

Network resource scheduling is carried out through CQI feedback uploaded by user terminals. In some scenarios with poor wireless environments (such as fast fading, strong interference, etc.) on the existing network, it is easy to cause delays in the process of CQI measurement, feedback and processing. And the scheduling results may be inaccurate, which not only affects user perception, but also increases the load on the terminal and the system virtually during the whole process
