Abstract

Provided is an LTE uplink resource scheduling method. According to the LTE uplink resource scheduling method, the optimal scheduling area of each user is determined by determining the resource grouping initial position of the user, and therefore it is ensured that certain resources can be scheduled for each user without being influenced by the small-scale change of the frequency domain. The method has low calculation complexity, and the spectral efficiency is remarkably improved on the premise that the user equality principle is ensured.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an LTE uplink resource scheduling method. Background technique [0002] In the future mobile communication system, high-bandwidth and high-speed data services are essential, which requires wireless communication technology to effectively eliminate the adverse effects of wireless channel fading on transmission, and achieve higher spectral efficiency. Take into account the equality among users. [0003] LTE (Long Term Evolution) is a long-term evolution of the UMTS (Universal Mobile Telecommunications System) technical standard formulated by 3GPP (Third Generation Partnership Project). The LTE system introduces key transmission technologies such as OFDM and MIMO, which significantly increases the spectral efficiency and data transmission rate. However, due to the limitations of other factors such as the size of the mobile terminal, it is difficult to configure...
