This article addresses downlink resource allocation strategies in LTE release 8, using orthogonal frequency division access (OFDMA). We consider 3GPP long‐term evolution resource allocation strategies for allocating higher‐layer data to the basic resource allocation units (slots) of OFDMA frames. Then, we introduce two simple allocation methods: adaptive slot allocation and reservation‐based slot allocation. Both approaches consider a fair resource allocation among different types of service data flow (SDF) by considering their quality of service (QoS) characteristics and their channel qualities. The ultimate objective of the proposed approaches is to maximize the capacity of the system subject to the QoS constraints for each type of SDF in terms of data rate and bit error rate.
