LTE基站调度框架设计
首发时间:2009-12-07
摘要:由于采用了OFDMA/SC-FDMA的多址接入技术,LTE系统的资源调度与基于CDMA的3G系统有本质的不同。除了可以采用传统的时域,码域调度机制,LTE系统可以更加灵活的调度频域资源。同时,LTE中引入的关键技术MIMO对位于MAC层的系统调度功能产生了一定的影响,本文在简要介绍调度器,调度流程和控制信令的基础上,分析了调度相关的技术原理,从而提出一种适用于LTE的基站MAC层调度框架,并简要分析了其中的调度策略。本调度框架的提出对研究后续系统LTE-Advanced的调度有一定的启发。

LTE eNodeB Scheduling Framework Design
Abstract:As a result of taking OFDMA / SC-FDMA as the multiple access technology, LTE had a different resource scheduling scheme from 3G. In 3G system which is based on CDMA, the traditional scheduling is in time domain and code domain while the LTE scheduling scheme can be more flexible in frequency domain. MIMO as a key technology in LTE had an impact on scheduling function in MAC layer. In this paper, we introduced the scheduler, scheduling processes and scheduling related control signaling, based on the description of scheduling related technology theory, we give a LTE eNodeB scheduling framework on MAC layer, and a brief analysis of one of the scheduling strategy. The proposed scheduling framework had inspired on the future research object?LTE-Advanced system.
