    摘要: A method for configuring gain factors in a WCDMA telecommunication system is provided in which the gain factor for defining power required for normal reception of uplink data in an environment supporting an uplink service over an E-DCH can be configured using minimal signaling information. First gain factors for first TFs corresponding to a part of a TF set including a plurality of TFs available for an uplink service are received. One of the first TFs is determined as a reference TF for a second TF other than the first TFs in the TF set. Then, a second gain factor for the second TF is calculated using the first gain factor for the determined reference TF. The second gain factor is used for transmitting or receiving uplink data.

    摘要: A method and an apparatus for data transmission in a mobile telecommunication system supporting an enhanced uplink service are provided. A Transport Format Combination (TFC) selector determines TF information for data to be transmitted through a first data channel not supporting Hybrid Automatic Repeat reQuest (HARQ) and a second data channel supporting HARQ, and determines gain factors for the first and second data channel, and first and second control channel carrying control information for the first and second data channel. The gain factors are input to a physical channel transmission controller, and the physical channel transmission controller scales-down the gain factor for the second channel if total transmit power required for transmission of the channels exceeds the predetermined maximum allowed power. A gain scaler adjusts transmit powers of the channels using the scaled gain factor and gain factors for the first data channel, the first control channel and the second control channel.

    摘要: A method and apparatus for transmitting a pilot signal in a wireless communication system. A reference cell scrambling code or one of a plurality of additional cell scrambling codes is selected for each combination of one of a plurality of first scrambling codes (PSCs) applied to a first synchronization channel (P-SCH) and one of a plurality of second scrambling codes (SSCs) applied to a second synchronization channel (S-SCH). It is determined whether to transmit the pilot signal using the reference cell scrambling code or one of the plurality of additional cell scrambling codes. The reference cell scrambling code or the additional cell scrambling code is generated according to the determination. The pilot signal is transmitted using the generated reference cell scrambling code or the additional cell scrambling code.
