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.

An apparatus and method for providing a broadcasting service in a mobile communication system. The apparatus and method can transmit broadcasting service data using orthogonal frequency division multiplexing (OFDM) symbols in the mobile communication system. Broadcasting service data is encoded and modulated. The modulated data is demultiplexed into data streams corresponding to a number of orthogonal frequency subcarriers. The data streams are transformed using Fast Fourier Transform (FFT). The transformed data streams are multiplexed using OFDM. Information with a predetermined length placed in a last part of OFDM data is copied. The copied information is added as a cyclic prefix (CP) to a head part of the OFDM data, and OFDM symbols to be transmitted are generated. The generated OFDM symbols are multiplexed into a forward channel of the mobile communication system, and the multiplexed OFDM symbols are transmitted.

A system and method for controlling data rates of a reverse packet data in mobile communication system for transmitting reverse packet data from a mobile station to a base station over a reverse packet data channel at a plurality of data rates. The present invention provides an apparatus and method for improving throughput of an entire system by enabling a base station's scheduler to rapidly assign reverse resource for a mobile station that has completed its data transmission to other mobile stations.

Disclosed is a method for controlling a reverse data rate by a mobile station in a mobile communication system supporting high-rate packet data transmission. The method includes receiving average loading information (FRAB) from a particular base station when the mobile station attempts an initial access to the base station; setting the received average loading information as average loading information for the base station; and upon receiving reverse activity information (RAB) from the base station, controlling a rate of reverse data using the received reverse activity information and the set average loading information.

摘要:
A reduced slot cycle (RSC) mode control method is provided for observing a paging slot by a mobile station to receive a message transmitted from a base station in a mobile communication system. The method includes the steps of determining at least one parameter related to an operation time of the RSC mode and the number of operation periods where the mobile station operate with different slot cycle indexes (SCIs), through an exchange of at least one message with the base station, calculating a per-SCI operation time in the RSC mode operation time using the determined parameter, and starting the RSC mode, setting a reduced slot cycle index (RSCI) as an initial value of the SCI determined between the mobile station and the base station, wherein the RSCI has a value smaller than an SCI value of an idle state, increasing the SCI value step by step each time the SCI operation time of slot period arrives, and terminating the RSC mode if the increased SCI value reaches the SCI value of the idle state.
