Apparatus and method for transmitting/receiving packet data symbol in a mobile communication system

Abstract From the Canadian patent

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 pilotto-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-todata tone power ratio. A transmitter transmits the packet data symbol.
