    • A method for managing and allocating radio resources (RRMA method) of multiple radio resource types to subscriber stations is disclosed. The RRMA method includes bandwidth partitioning, into parts comprising “slots” with a given reuse pattern, a selection rule, to select a “cell, reuse pattern” pair serving each user, and an allocation rule, for distributing to each user an appropriate number of bandwidth slots from the selected “cell, reuse pattern” pair. After an adaptation period, the method reaches a desired fairness, while simultaneously reaching a maximal mean throughput, possible under this fairness. For big networks, the method provides basically decentralized radio resource management. The RRMA method is useful to cellular networks having a single set of orthogonal sub-channels (frequency/time slots) being reused by all network cells, such as time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), or OFDMA/TDMA cellular systems. Particularly, the method is applicable in fractional frequency reuse cellular networks.
    • 公开了一种用于向用户站管理和分配多种无线电资源类型的无线电资源(RRMA方法)的方法。 RRMA方法包括带宽划分,包括具有给定重复使用模式的“时隙”的部分,选择规则,以选择为每个用户提供服务的“小区,重用模式”对以及分配规则,用于向每个用户分配适当的号码 来自所选择的“小区,重用模式”对的带宽时隙。 在适应期后,该方法达到期望的公平性,同时达到最大平均吞吐量,这在公平性下是可能的。 对于大型网络,该方法基本上提供了分散的无线资源管理。 RRMA方法对于具有由所有网络小区重新使用的单组正交子信道(频率/时隙)的蜂窝网络是有用的,诸如时分多址(TDMA),正交频分多址(OFDMA)或 OFDMA / TDMA蜂窝系统。 特别地,该方法适用于分数频率复用蜂窝网络。
