Abstract: PURPOSE: A method of allocating resources for cooperative diversity is provided to guarantee QoS(Quality of Service) of a fixed level for each user while improving a data transmission rate of the entire system. CONSTITUTION: Channel conditions about each source station are obtained(S610). One or more subcarriers are exclusively allocated to each source station based on the channel conditions. A relay station about each source station is selected(S620). Cooperative diversity is performed using the same subcarrier as a source station to which the relay station corresponds. The subcarrier is assigned to satisfy a minimum data rate necessary for each source station for service quality satisfaction of a user.
Abstract translation: 目的：提供一种分配资源以进行协同分集的方法，以保证每个用户固定级别的QoS（服务质量），同时提高整个系统的数据传输速率。 构成：获得关于每个源站的信道条件（S610）。 基于信道条件将一个或多个子载波专门分配给每个源站。 选择关于每个源站的中继站（S620）。 使用与中继站对应的源站相同的子载波来执行协同分集。 分配子载波以满足每个源站对用户的服务质量满意度所需的最小数据速率。

Abstract: PURPOSE: A resource allocation method of an E-node B and an apparatus thereof in a multiple user MIMO-OFDMA system is provided to increase transmission efficiency by properly allocating a resource in a channel environment. CONSTITUTION: An E-node B allocates UEs(User Equipments) to each sub carrier in one or more types(400). The E-node B calculates transmission power based on information related to a space path(402). The E-node B stores sum of data rate if the calculated transmission power is the maximum transmission power(406). The E-node B selects total sum in a resource assignment algorithm(409).
Abstract translation: 目的：提供多用户MIMO-OFDMA系统中的E节点B的资源分配方法及其装置，通过在信道环境中适当分配资源来提高传输效率。 构成：E节点B以一种或多种类型（400）为每个子载波分配UE（用户设备）。 E节点B基于与空间路径相关的信息来计算发送功率（402）。 如果所计算的发送功率是最大发送功率，则E节点B存储数据速率的总和（406）。 E节点B在资源分配算法（409）中选择总和。
