    摘要: 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) is provided, in which a multiplexing mode is selected for multiplexing a Distributed Resource Channel (DRCH) and Localized Resource Channel (LRCH) over orthogonal frequency resources, in which it is determined 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, resources are allocated in an Synchronous HARQ S-HARQ scheme if the persistent resource allocation is used, and resources are allocated in a Resource Adaptive S-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.

    摘要: An interleaving and deinterleaving apparatus and method in a wireless communication system are provided, in which it is determined whether coded bits to be transmitted in one modulation symbol are selected from a plurality of code blocks. The coded bits are interleaved on a modulation symbol basis if the coded bits to be transmitted in the modulation symbol are selected from a plurality of code blocks.

    摘要: A base station includes a transmit path circuitry to scramble CRC bits of a DCI format using a C-RNTI for dynamic scheduling, and scramble the CRC bits of the DCI format using an SPS C-RNTI for semi-persistent scheduling. If C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being a fallback format to indicate a transmit diversity transmission scheme or a single-layer beamforming scheme, and uses the DCI format being a dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme.If SPS C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being the fallback format to indicate a single-DRS port transmission scheme, and uses the DCI format being the dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme.

    摘要: Disclosed is an apparatus and a method for transmitting a control channel message, which can reduce resource waste in an OFDM system multiplexing and using a Block Resource Channel (BRCH) and a Distributed Resource Channel (DRCH) in a frequency axis. The apparatus includes a controller for generating a predetermined field and outputting a control channel message including the predetermined field, the predetermined field indicating a precoding index when a common pilot is used for data demodulation in a mobile station and indicating a pilot format of a dedicated pilot when the dedicated pilot is used for data demodulation in the mobile station, the precoding index indicating a weight value for beam-forming of each antenna; and a transmission module for converting the control channel message into a wireless signal and transmitting the wireless signal to the mobile station. The apparatus and method can reduce the resource waste of a control channel by inserting different pieces of information into a predetermined field included in the control channel message according to the channel type and the multiplexing mode of a resource channel in an Orthogonal Frequency Division Multiplexing (OFDM) system, and enables the efficient use of resources by transmitting different types of control information through redundant bits of a control channel message.
