Abstract: A packet data generating method and apparatus for supporting multiple services in a wireless packet data communication system where an MS transmits two or more traffics to a BS on one of a reverse PDCH, a reverse FCH, and a reverse DCCH. To generate a PDU using non-signaling traffic and/or signaling traffic for one of the reverse physical channels, a multiplex option is determined during service negotiations between the MS and the BS. The multiplex option defines a traffic format having a header and a payload including traffic data, and the header includes a service reference identifier field, a length indicator field indicating the presence or absence of a length field, and the length field indicating the length of the traffic data. A PDU is generated by formatting a reverse traffic to have a header and a payload according to the determined multiplex option.

Abstract: 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.
