MIMO-OFDM中基于业务类型的跨层资源分配研究

Cross-layer Resource Allocations in MIMO-OFDM Wireless Networks Based on Diverse Service Types

提出了一种基于PHY层和MAC层的跨层资源自适应方案。该方案首先把业务类型划分为实时业务和非实时业务,并在此基础上针对业务类型在MAC层对分组进行调度和在PHY层对子载波和功率分配。

We proposed a scheme for cross-layer resource allocation between PHY layer and MAC layer. Firstly, our scheme differentiated the real-time services from non-real-time services. Secondly, based on diverse service types, we proposed a scheduler in MAC layer and an algorithm for subcarriers and power allocation in PHY layer.
