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 apparatus for transmitting/receiving a Channel Quality Indicator (CQI) in a communication system are provided. It is determined whether there is any uplink data to transmit, when a CQI transmission time arrives according to a predetermined CQI transmission period. If there is uplink data to transmit, a part of the uplink data is punctured to insert the CQI therein, and the inserted CQI is multiplexed with the uplink data before transmission. It is determined whether there is any uplink data to receive from a terminal, when a CQI reception time arrives according to a predetermined CQI transmission period. If there is uplink data to receive, the uplink data is received from the terminal, and the received uplink data is demultiplexed to extract the CQI.

摘要： A sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal using the multiple antenna technique is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. Moreover, the sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. The sounding reference signal is transmitted through an antenna pattern in which the sounding reference signal can be transmitted through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead in this environment.

摘要： An apparatus and method in which an Enhanced Uplink Dedicated transport CHannel (EUDCH) is used in a Wideband Code Division Multiple Access (WCDMA) system is provided. In a User Equipment (UE), when physical channels for transmitting EUDCH data are transmitted in addition to existing physical channels, a Peak-to-Average Power Ratio (PAPR) of an uplink transport signal increases. The increase in PAPR depends upon Orthogonal Variable Spreading Factor (OVSF) codes allocated to the corresponding physical channels and In-phase/Quadrature-phase (I/Q) channels. Therefore, the apparatus and method allocate optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH.
