摘要:
A method and an apparatus for reporting a buffer status of a buffer storing packet data to be transmitted by a user equipment for a scheduling assignment of an uplink packet data service in a mobile communication system supporting the uplink packet data service are disclosed. A user equipment stores packet data having a priority corresponding to a plurality of priority queues having inherent priorities and relating to at least one service, and transmits buffer status information containing queue identifiers of the priority queues and buffer payload information representing an amount of the packet data stored in the priority queues. Herein, the user equipment inserts the buffer status information into a header part of a protocol data unit for the uplink packet data service, inserts the packet data into a payload part of the protocol data unit, and then transmits the protocol data unit.

An apparatus and method of transmitting scheduling information from a UE to a Node B to request Node B controlled scheduling in an asynchronous CDMA communication system supporting an E-DCH packet data service is provided. The UE generates a MAC-e PDU including only scheduling information representing a buffer status and a power status in relation to uplink data transmission, and transmits the MAC-e PDU on an E-DCH along with TF information indicating the transmission of the MAC-e PDU including the scheduling information. The Node B receives the scheduling information on the E-DCH and schedules uplink data transmission according to the scheduling information.

摘要:
Disclosed is a method and apparatus for providing uplink packet data services through an E-DCH in an asynchronous WCDMA system. A transport block size (TBS) for transmitting uplink transport channel data is determined. A combination of a spreading factor and a modulation scheme for uplink channel data transmission, corresponding to the determined TBS, is selected according to transmittable physical channel data bit sizes and puncturing limit values. The TBS is transmitted by incorporating it into control information of the uplink transport channel data. The modulation scheme and spreading factor combination is determined based on a physical channel data bit size that maximizes transmission efficiency and minimizes the number of punctured bits, without requiring an additional physical channel in transmitting the uplink data having the TBS. This method maximizes uplink transmission efficiency to save transmission resources and reduces signaling overhead required to transmit E-DCH control information.

A method and apparatus selects serving scheduling Node B for efficiently controlling and scheduling uplink traffic transmission from user equipments (UEs) located in a soft handover region. The UE selects a serving scheduling cell among cells included in its active set and transmits information on the selected serving scheduling cell to a Node B through uplink signaling. A service scheduling cell and non-serving scheduling cells efficiently control uplink traffic from the UE through independent scheduling. The efficient use of uplink resources contributes to an increase in the entire system performance and system stability.

Disclosed is a power setup method for minimizing a delay time caused by an HARQ of an E-DCH when an MAC-e PDU comprising scheduling information required for using a Node B controlled scheduling is transmitted in environments supporting a packet data service through the E-DCH in an asynchronous code division multiple access (CDMA) communication system. A user equipment (UE) generates packet data for transmitting through the E-DCH, determines if signaling information is included in Quality of Service (QoS) of the packet data and the packet data, sets a power gain preset according to each QoS of the packet data, applies a determined offset value to the set power gain when the signaling information is included in the packet data, and transmits the packet data through the E-DCH according to the power gain to which the offset value has been applied.

摘要:
A method and apparatus for efficiently controlling uplink traffic rates, performing scheduling accompanied by fast rate ramping, and transmitting uplink rate assignment information in an asynchronous WCDMA communication system. A Node B determines an allowed current rate for an uplink channel. If the difference between the current rate and the previous rate is two or more levels, the Node B transmits a rate indication indicating the current rate. If the difference between the current rate and the previous rate is zero or one level, the Node B transmits a rate up/down indicating a rate change from the previous rate to the current rate. Also the Node B may transmit the rate indication instead of the rate up/down, periodically or in an event-triggered manner.
