Abstract

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.
