User terminal group scheduling method and device

Abstract

The embodiment of the invention provides a user terminal group scheduling method and device. The method comprises steps: measurement report information reported by the user terminal is received, wherein the measurement report information comprises the identity of the user terminal, measurement time, frequency point information corresponding to a main service cell and a neighbor cell of the user terminal and reference signal receiving power information; according to the measurement report information, the signal to interference and noise ratio of the user terminal is calculated according to a first preset rule; a user terminal with the signal to interference and noise ratio larger than a preset threshold is used as a cell center user group, and a user terminal with the signal to interference and noise ratio smaller than the preset threshold is used as a cell edge user group; and according to a second preset rule, a first network resource scheduling algorithm and a second network resource scheduling algorithm are adopted to carry out network resource scheduling for the user terminals in the cell center user group and the cell edge user group respectively. The device is used for executing the above method. The embodiment of the invention reduces the network scheduling time, and the network resource scheduling speed is further improved.

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
