    摘要: A transmission/reception apparatus for transmitting packet data in an Orthogonal Frequency Division Multiplexing (OFDM) system. The apparatus includes a transmission module for generating a frame of an OFDM symbol including pilot tones using the packet data, and transmitting the frame to a wireless network; and a controller for changing at least one of a Pilot-to-Data Ratio (PDR) of the pilot tones and a density of the pilot tones based on a length of the frame. The reception apparatus includes a reception module for receiving a frame of an OFDM symbol including pilot tones from a wireless network, extracting the pilot tone from the received frame, performing channel estimation thereon, and demodulating the packet data; and a controller for receiving at least one of a PDR of the pilot tone and a density of the pilot tone, both of which are in proportion to a length of the frame, and controlling the reception module so that the channel estimation is performed, based on the received information.

    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: A method for transmitting/receiving resource allocation information in a mobile communication system using a shared control channel. The transmission method includes performing scheduling for resource allocation to a plurality of terminals; generating, in a bitmap, information indicating allocation/non-allocation of resources which are not sequentially allocated beginning from a particular terminal using the scheduling result; and transmitting, over the shared control channel, resource allocation information including a terminal identifier and a resource allocation bitmap of each terminal. The reception method includes receiving from a wireless network a shared control channel including resource allocation information; determining whether a terminal identifier included in the resource allocation information is equal to a terminal identifier of the terminal; and updating a size of an available resource set according to a resource allocation bitmap for reception of next resource allocation information, if the included terminal identifier is not equal to the terminal identifier of the terminal.

    摘要: A method for transmitting/receiving a data control channel in a wireless communication system that transmits packet data. The transmission method includes transmitting packet data over a packet data channel, transmitting a control channel and receiving an ACKnowledgement (ACK) signal from a terminal that has received the control channel. The reception method includes receiving packet data and a control channel, acquiring control information by demodulating the control channel, and detecting an error in the control channel, and sending the error detection result to a base station as an ACK signal, if the control channel has been transmitted to the terminal itself.
