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 increasing the scheduling performance of a system supporting an uplink data service and total system stability by effectively UE status information to a Node B in a mobile communication system supporting the uplink data service are provided. UE status information including buffer occupancy information and transmit power status information is transmitted to a Node B periodically or upon generation of an event, irrespective of the presence or absence of uplink data to be transmitted. Since the buffer occupancy information and the transmit power status information are transmitted to the Node B by MAC-e signaling, physical channel resources are saved and E-DCH performance is improved.

摘要： A method and apparatus for scheduling uplink data transmission for a UE in a mobile communication system supporting an uplink packet data service are provided. A serving Node B and at least one non-serving Node B are included in an active set of a UE located in a soft handover region. The UE receives a dedicated scheduling grant from the serving Node B by dedicated scheduling and a common scheduling grant from the at least one non-serving Node B, controls an uplink data rate not to exceed a previous uplink data rate during a predetermined validity duration, if the common scheduling grant indicates a rate-down, and transmits uplink data at the controlled uplink data rate.

摘要： The present invention supposes a situation in which an Enhanced Uplink Dedicated transport Channel (EUDCH) is used in a Wideband Code Division Multiple Access (WCDMA) system. 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 present invention proposes an apparatus and method for allocating optimum OVSF codes and I/Q channels to EUDCH-related physical channels in order to minimize an increase in PAPR due to EUDCH.

摘要： A method and apparatus for transmitting a control channel in a base station for a wireless communication system. The base station transmits information including a number of channel elements constituting control channels, to a terminal; establishes a set of control channels that the terminal can receive, within the number of channel elements using an identifier (ID) of the terminal; and transmits control information to the terminal through a selected control channel among the control channels. The terminal is restricted to monitor only a proper number of control channels established without the need to monitor all control channels, thereby reducing reception complexity and avoiding unnecessary battery consumption.
