摘要:
Disclosed is a method for allocating resources in a base station of a wireless communication system that performs communication using frequency resources. The method includes dividing subcarriers into subcarrier sets each including a predetermined number of consecutive subcarriers, and generating a resource index table mapped to consecutive indexes such that a distance between subcarriers in the subcarrier sets is maximized; and determining an amount of resources to be transmitted through a downlink according to a channel condition, for data to be transmitted to each terminal, and allocating resources to the terminal using the index value in the resource index table.

摘要:
An apparatus and method transmits a packet data symbol in a high-rate packet data (HRPD) mobile communication system for broadcasting service. A transmission processor generates a modulated symbol by encoding, interleaving and modulating a physical layer packet to be transmitted, and arranges the modulated symbol in a data tone. A tone inserter inserts a guard tone and a pilot tone into the data tone. A tone power allocator sets a different pilot-to-data tone power ratio according to a position of a slot, in which the packet data symbol is included, and allocates power according to the pilot-to-data tone power ratio. A transmitter transmits the packet data symbol.

An apparatus and method for multiplexing packets for broadcast services in a mobile communication system based on orthogonal frequency division multiplexing (OFDM). The OFDM system has a transmission structure in which one slot includes at least two symbols, and each symbol includes a plurality of subcarriers. Different broadcast service packets received from at least two channels are multiplexed into one slot and a result of the multiplexing is transmitted. Overhead information of the channel packets multiplexed into the one slot is generated and transmitted.

摘要:
A method for receiving resources allocated from a base station by a terminal in an OFDMA mobile communication system. The method includes receiving, for a data channel, a number of first components, which indicates an amount of resources used with a first resource allocation scheme, and a number of second components, which indicates an amount of resources used with a second resource allocation scheme, from the base station over a common control channel; determining first and second identifier lengths of channel elements for the first and second resource allocation schemes according to the number of first components and the number of second components; receiving resource allocation information including an identifier indicating at least one channel element allocated to the terminal, over a data control channel using one of the identifier lengths; and transmitting and receiving data over a resource of a channel element indicated by the received identifier.
