摘要:
A reverse data transmission apparatus and method in a mobile communication system. A mobile station receives information about an MADR (Maximum Allowable Data Rate) from a base station in a first predetermined frame period, determines a data rate equal to or lower than the MADR, and requests the determined data rate to the base station. If an MADR received from the base station in a second frame period following the first frame period is higher than the requested data rate, the mobile station starts data transmission. Then, the mobile station measures a traffic to pilot ratio (T/P) from the base station and controls the data rate according to the T/P during data transmission.

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.
摘要:
A reverse transmission controlling method in a mobile communication system. After receiving forward information commanding a reverse data rate change on a forward channel from a base station, a mobile station increases its reverse data rate to a data rate equal to or lower than a maximum data rate if the forward information commands a reverse data rate increase, determines whether the increased data rate can be further increased for the next frame, and transmits the determination result with information representing the increased data rate to the base station.

A PLP transmitting method in a mobile communication system is provided. A base station determines a forward data rate according to DRC information received from a mobile station, reads out temporary EPs of a maximum total size from the buffers, determines whether the temporary EPs can be transmitted at the data rate, forms a combination of logical EPs from the temporary EPs if the temporary EPs can be transmitted at the data rate and the total size of the temporary EPs is equal to or greater than a threshold, and transmits the logical EPs in a PLP.

An apparatus and method for controlling a reverse data rate in a mobile station. The method includes determining whether the mobile station has sufficient power to transmit at an increased data rate compared to a current data rate, and transmitting a determination result to a base station.
摘要:
A reverse link controlling method in a mobile communication system. To increase or decrease a reverse data rate, an MS receives threshold power information indicating a power threshold for a pilot channel from the BS and measures the reception power of the pilot channel received from the BS. When the MS is supposed to increase or decrease the current data rate, it increases the current data rate by two levels or decreases the current data rate by one level if the pilot reception power is higher than the power threshold, and increases the current data rate by one level or decreases the current data rate by two levels if the pilot reception power is equal to lower than the power threshold.

摘要:
A scheduling method for providing multimedia service and packet data service efficiently. The scheduling is a Round-Robin scheduling in an MQC (Multiple Quality Control) protocol structure. A transmitter in a base station transmits or retransmits TUs from different streams in a PLP using priority queues by the scheduling.
摘要:
A reverse transmission controlling method in a mobile communication system, after receiving forward information, commanding the increase or decrease of the reverse data rate received on a forward control channel from a base station, a mobile station determines whether the previous rate increase available information transmitted to the base station on a reverse control channel before reception of the forward information indicates that a reverse data rate increase is available, if the forward information commands a reverse data rate increase. The mobile station increases the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmits reverse data at the increased reverse data rate.

There is provided a novel architecture for transmitting multimedia data with different QoSs in a mobile communication system. In a protocol structure according to the present invention, an RLP layer receives data with different QoSs and dividing the data into datagrams according to the QoSs, a MUX layer multiplexes the datagrams received from the RLP layer and outputs multiplexed TU data, and a QCCH receives the multiplexed TU data and outputs TU blocks with the QoSs by puncturing and repeating information added according to the QoSs for the multiplexed TU data.
