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.

摘要： Disclosed is a method for transmitting a dedicated physical data channel signal over a dedicated physical data channel in the absence of transmission data to be transmitted over the dedicated physical data channel in order to properly maintain a target SIR (Signal-to-Interference Ratio) when there exists new transmission data after the absence of the transmission data in a CDMA (Code Division Multiple Access) mobile communication system. The method comprises generating a dummy bit generation request signal in the absence of the transmission data; and upon receipt of the dummy bit generation request signal, generating a dummy bit stream, and transmitting a dedicated physical data channel signal created by attaching the CRC bit stream to the dummy bit stream.

摘要： In an asynchronous CDMA mobile communication system supporting HSDPA (High Speed Downlink Packet Access), in order to assign power to a high speed physical downlink shared channel (HS-PDSCH), a power offset is determined and then provided to a Node B and a user equipment (UE). For this, an HS-PDSCH power offset is determined by a controlling radio network controller (CRNC) and a Node B, and then transmitted to the UE or the Node B.

摘要： 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.

摘要： 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.
