Embodiment Construction

[0042] Matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of exemplary embodiments of the present invention. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0043] Exemplary embodiments of the present invention propose a method and a transceiver thereof for determining the resource assignment priority of resource blocks assigned to a particular user according to reliability based on overall channel conditions, and assigning each resource according to the priority The systematic bits and the parity bits of the blocks are used to transmit the systematic bits in coded bits in a better channel environment in an Orthogonal Frequency Di...

Abstract

An apparatus and method for transmitting and receiving data in an Orthogonal Frequency Division Multiple Access (OFDMA) system using a plurality of resource blocks are provided, in which a transmitter generates a sub-packet to perform a Hybrid Automatic Repeat reQuest (HARQ) function on the data, performs interleaving on the generated sub-packet for each resource block for a receiver according to predetermined order, and transmits a control message including the sub-packet for each resource block and allocation information of the sub-packet to mobile stations. A mobile station deinterleaves the sub-packet received from the base station for each resource block, and combines the deinterleaved sub-packet based on the control message.

Description

technical field [0001] The present invention generally relates to devices and methods for transmitting and receiving data in mobile systems. More particularly, the present invention relates to an apparatus and method for transmitting and receiving data in an Orthogonal Frequency Division Multiple Access (OFDMA) system, and a system thereof. Background technique [0002] Mobile communication systems have been developed for providing communication services to users regardless of their locations. For communication, a mobile communication system uses its limited resources to identify users. There are various possible access schemes depending on how the limited resources are used. For example, a scheme that uses specific code resources to identify users is called a code division multiple access (CDMA) scheme, a scheme that uses time resources to identify users is called a time division multiple access (TDMA) scheme, and a scheme that uses frequency resources to identify users ...
