Abstract: A mobile station in a control hold mode wakes up at a time slot on a wake-up channel received from a base station, assigned thereto, and detects at least one predetermined indicator bit. If the detected indicator bit indicates that the base station has data to transmit, the mobile station starts monitoring a forward packet data control channel from the base station, in order to determine whether to make a transition to an active mode. Otherwise, if the detected indicator bit indicates that the base station has no data to transmit, the mobile station maintains the control hold mode, thus preventing unnecessary power consumption.

Abstract: A method, apparatus, and system for negotiating a session between an access terminal (AT) and an access network (AN) that can simplify a repeated negotiation procedure when the session is configured/updated/deleted between the AT and the AN. The AN performs protocol-by-protocol negotiations with the AT for a session configuration. The AN sends, to the AT, a soft configuration complete message including a continue bit indicating if another session configuration is added. The AN and the AT store a negotiated session configuration mapped to a personality index indicated in the message. When all session configurations have been completed, the AN and the AT determine if a session configuration currently in use has been changed. If the session configuration in use has not been changed, the AT and the AN maintain a physical channel. Moreover, the AN sends information indicating if a specific session configuration is applied after session configuration negotiation is completed.

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.
