Abstract:
1. A method for allocating resources in an Orthogonal Frequency Division Multiple Access (OFDMA) mobile communication system where data is transmitted by Hybrid Automatic Repeat reQuest (HARQ), the method comprising: selecting, from a plurality of multiplexing modes, a multiplexing mode for multiplexing a Distributed Resource Channel (DRCH) and a Localized Resource Channel (LRCH) over orthogonal frequency resources; determining whether to use persistent resource allocation for each slot, if the selected multiplexing mode is a multiplexing mode that punctures the DRCH onto the LRCH; allocating resources in a Synchronous HARQ (S-HARQ) scheme if the persistent resource allocation is used; and allocating resources in a Resource Adaptive Synchronous HARQ (RAS-HARQ) scheme if the persistent resource allocation is not used and resources are to be reused when early termination of HARQ transmission occurs, wherein during the persistent resource allocation, once resources are allocated, an initial transmission packet is sent without a control signal when packet transmission is performed within a predetermined transmission period.
